Before the use of forestry equipment, it is necessary to check the overall situation of the working area, which is to prevent the blade from being damaged by stones and other debris when the forestry equipment is running. It should also be noted that the continuous working time of forestry equipment cannot exceed four hours, such as the area of mowing is too large, can be repaired in batches. For forestry equipment, it will not heat up due to long continuous use, and the operator will not feel tired due to too long working time.
Before the use of forestry equipment, it is necessary to check the overall condition of the equipment, especially the inspection of screws and wearing parts. This step is very simple but many people ignore it, requiring special attention.
So how to choose the right forestry equipment for you? Be clear about your needs, that is, how large the area of the maintenance lawn is, the main terrain, there are no obstacles, and there are working hours. This needs to be clear, the general garden lawn maintenance, household small forestry equipment can adapt to various occasions, and the efficiency is relatively high. In addition, the advantage of lithium battery forestry equipment is low noise, which is important for household use. Because noise is a very unfriendly behavior to neighbors and may affect interpersonal relationships.
forestry equipment is a very popular equipment in foreign countries, one of the reasons is that most families abroad have large lawns that need to be mowed regularly, so every family has forestry equipment. With the improvement of living standards, domestic demand is also increasing, so for domestic users, lithium battery forestry equipment is more suitable, or the same reason: low noise. The courtyard of the home is generally very close to the neighbors, so low noise is a factor that needs to be considered.

integrated transfer machine Tail frame with fast CAM clamping device, high working efficiency. There is a device in the tailstock sleeve to prevent the bit from rotating, which avoids the damage of the inner hole taper of the tailstock sleeve caused by misoperation, and effectively protects the tailstock components.
The tail seat is faulty. Generally, the tail seat is installed on the guide rail of the inclined bed. When moving, the hydraulic system builds pressure and compresses the disc spring inside the tailstock, releases the clamping device between the tailstock and the guide rail, and moves on the guide rail through the servo motor drive. When the drive is stopped at any position, the hydraulic system stops working, the pressure is unloaded, and the disc spring instantly restores the elasticity, so that the tail seat is clamped and positioned on the guide rail.
During processing, it was found that the tail seat shifted back when the workpiece was jacked up, so that the workpiece was in the condition that only the chuck was clamped separately, and the long-axis parts could not be processed. Below, Xiaobian analyzes and adjusts the integrated transfer machine from the inside out. The equipment is in an environment with high temperature, large dust and large water vapor content in the air, among which dust and high temperature are very harmful.
The friction plate may be stuck because the clutch plate is too loose, and when processing products, it is easy to hold the car. Too tight will not work, will accelerate the clutch wear. And you can't lift it too tight. When processing products, especially when picking thread with reverse car, the clutch plate is too tight and easy to crash.
Open the headstock cover, push the positioning pin in with a screwdriver, adjust it to the appropriate pin opening, and then pop it out. Adjust the pressure of the oil, the friction plate will not be adjusted. In the rear housing there is a spring with about 100 long screw, to the right of the rear spindle, the front two nuts are to regulate the clutch.
If the parking brake is not easy or the integrated transfer machine friction sheet is stuck, open the head cover to see a black wrench on the top of the clutch, tighten it and try again, if the smoke is generally the clutch is too loose or the lubricating oil is too little, the clutch has positive and negative sides, both sides should be evenly adjusted, if the clutch is burned, The noise will be larger, the speed difference will be larger.

What is a rail tie plate? With the progress of time and the development of The Times, universal data testing machines have gradually increased. It is recommended that you check whether there is oil leakage, whether the bolts can be tightened, whether the electricity is intact, check regularly, and adhere to the integrity of its parts.
When we talk about the rail tie plate, I believe there are many people who do not know much about it. I don't know what it is. In fact, the rail tie plate is mainly based on high pressure oil source as the power source, servo valve or proportional valve as the control element, closed-loop active control, therefore, in use is its high control function, generally can complete the load, displacement, strain three control methods. In addition, when we see it, we also need to understand that the equipment electro-hydraulic servo testing machine has a large tonnage and a strong carrying capacity, so its loading stability is good in this phone. The special software has a variety of control methods, so it has the characteristics of flexible application and high function. It is generally used in the form of half wave rectification, the positive terminal is connected to the high voltage output terminal, and its negative terminal will output a positive high voltage, if it is connected to the high voltage output terminal, the positive terminal will output a negative high voltage. If you explain it this way, I believe you will understand. In fact, from a structural point of view, its unit weight output power and unit size output power in the four types of transmission is quite good, this time its hydraulic universal testing machine moment of inertia ratio is very large.
rail tie plate also has the advantages of small size, light weight, high mechanical strength, easy to use and no radiation, it is because of these reasons that it is favored by everyone. So it can be seen in many places. In fact, the rail tie plate's working performance, speed, torque and power can be adjusted stepless. The hydraulic universal testing machine has fast response, fast reversing speed change, wide speed regulation range, and good action speed. In this case, it will naturally make its control and adjustment simple, easy to operate and labor saving, easy to cooperate with electronic control, and it is completely easy to connect with CPU(computer) at work, and easy to realize automation. At the same time, it is easy to realize overload protection and pressure preservation, safe and reliable; Components are easy to serialize, standardize and generalize.

At present, our country Notebook Printing wholesale design still has many problems. For example, the name and batch number of the drug are not standardized, the use of the drug is inconsistent with quality standards, the terminology is not standardized, the drug is over-packaged, there is no manual, etc., and the design is not ethnic. It does not meet the country's cultural and public aesthetic needs. Experts said that the medical packaging design should also be humanized, pay attention to simple and practical easy to operate. However, a large part of the current domestic medical packaging design does not consider these links. These are the real headlines that pharmaceutical packaging companies must pay attention to and address. Seize the opportunity to achieve development. With the continuous deepening of China's medical system reform, the backwardness of pharmaceutical packaging will undergo fundamental changes.
At present, China continues to introduce and update pharmaceutical packaging machinery and materials, and the pharmaceutical packaging industry will present a new situation. In addition, the diversification of drug types also brings opportunities to the pharmaceutical packaging industry. In recent years, the packaging speed of solid drugs such as capsule injections in China is very fast, and the use of disposable plastic syringes for injection packaging and application With major changes, the improvement of infusion packaging is also developing in the direction of composite flexible packaging and plastic packaging.
In the national "Twelfth Five-Year" development plan, the pharmaceutical industry is listed as one of the key tasks of national economic development, which has injected new vitality into the pharmaceutical packaging industry. In recent years, with the clear registration standards related to pharmaceutical packaging, China's pharmaceutical packaging industry continues to develop and grow, safe and stable, cost control of medical packaging design has attracted more and more attention.
Notebook Printing wholesale machinery should shift its focus to technology
Due to the lack of technology, China's Notebook Printing wholesale machinery is mainly based on price war to attract foreign businessmen. As the demand for more and more high, low prices are not the focus of their pursuit. Pharmaceutical packaging machinery should transfer the price to technology, and technology upgrading is king.
Due to the technical level of product reliability and other reasons less, China's packaging machinery products face fierce international competition. In the past development of the road, the domestic packaging machinery due to low prices, is indeed very popular. However, with the improvement of industry requirements, pharmaceutical companies have gradually diversified their demand for packaging machinery, and the price has not become a competitive advantage. In the face of this situation, the domestic pharmaceutical packaging machinery needs to further accelerate the replacement of packaging machinery. Intelligence will enter the entire packaging machinery and production line. Therefore, the industry urgently needs to strengthen the reliability of equipment and production lines. Level of safety automation, such as unmanned operation. Introduce modern high-precision skills Electronic skills micro-electronic skills marginal skills fuzzy skills in order to strengthen competition.
New packaging machinery is usually the result of mechatronics, making full use of information products *. Some designers of Chinese companies are not familiar with electronic products and dare not choose, which greatly limits the improvement of packaging machinery. For example, many foreign new packaging machines use independent drive, so that the whole machine drive chain is greatly shortened, the structure is greatly simplified, and the working accuracy and speed are greatly improved. One of the core technologies is the use of multi-motor drive synchronization technology. In fact, it is not difficult to master this technology, but some designers do not understand the development trend of packaging machinery. Another core technology is the mass adoption of servo drives, but older designers would not design and select servo systems and their control systems.
The advanced Notebook Printing wholesale machinery uses a number of new inspection systems to ensure the stable and reliable operation of packaging machinery. With the increasing popularity of automation manufacturers and the development of information technology, more and more designers have accepted advanced automation technology and used advanced automation products to improve the performance of equipment.

As a kind of high speed, high efficiency, cost-effective production equipment, Full Automatic Hydraulic Machine is convenient to operate, simple process, to a great extent reduce labor waste. However, sometimes there will be faults such as unstable processing accuracy in internal or external situations, increasing the difficulty of problem elimination. Below, Yuhuan Yonggao summarizes several main reasons for the instability of machine tool processing accuracy to help everyone deal with it.
1, the workpiece size is accurate, the surface finish is poor
Fault cause: the tool tip is damaged, not sharp; The machine tool resonates and is not placed smoothly; Machine tool crawling phenomenon, processing technology is not good.
Solution: The tool is not sharp after wear or damage, then re-sharpen the tool or choose a better tool to re-set the tool; The machine tool has resonance or is not placed smoothly, adjust the level, lay the foundation, and fix smoothly.
The reason for mechanical crawling is that the guide rail of the drag plate is badly worn, the ball of the lead screw is worn or loose, the Full Automatic Hydraulic Machine should pay attention to maintenance, the wire should be cleaned after commuting, and the lubricating oil should be added in time to reduce friction; Choose the coolant suitable for workpiece processing, and choose a higher spindle speed as far as possible when it can meet the processing requirements of other processes.
2, the workpiece produces taper size head phenomenon
Fault cause: The level of Full Automatic Hydraulic Machine placement is not adjusted well, one high and one low, resulting in uneven placement; When turning a long shaft, the contributing material is relatively hard, the cutting tool is relatively deep, resulting in the phenomenon of letting the knife, and the tail seat thimble is different from the spindle.
Solution: Use the level to adjust the levelness of the machine tool, lay a solid foundation, fix the machine tool to improve its toughness; Choose a reasonable process and appropriate cutting feed to avoid cutting tool force, adjust the tail seat.
3, the driver phase light is normal, and the size of the workpiece processed is large and small
Fault cause: Full Automatic Hydraulic Machine drag plate long-term high-speed operation, leading to screw and bearing wear; The repeated positioning accuracy of the tool holder has a deviation in long-term use, and the drag plate can accurately return to the starting point of processing every time, but the size of the machined workpiece still changes. This phenomenon is generally caused by the spindle, the high-speed rotation of the spindle makes the bearing wear seriously, resulting in the change of processing size.
Solution: Use the dial indicator to lean against the bottom of the tool holder, and edit a fixed cycle program through the system to check the repeated positioning accuracy of the drag plate, adjust the lead screw clearance, and replace the bearing.
Check the repeated positioning accuracy of the tool holder with a dial indicator, adjust the machine or replace the tool holder; Use a dial indicator to check whether the workpiece is accurately returned to the program starting point, if possible, then overhaul the spindle and replace the bearing.

Generally speaking, stepper wire cutting machine is mainly composed of three parts, respectively: mechanical, working fluid system and electrical, each part has its own different roles and functions, among which:
1, working liquid system: the working liquid system is generally composed of working liquid tank, working liquid pump, liquid inlet pipe, liquid return pipe, flow control valve, filter cover or filter element. The main function is to concentrate the discharge energy, take away the discharge heat to cool the electrode wire and the workpiece, and eliminate the electrical corrosion products.
2, mechanical: stepper wire cutting machine mechanical part is the foundation, its accuracy directly affects the working accuracy of the machine tool, but also affects the full play of the electrical performance. The mechanical system consists of machine tool bed, coordinate table, wire transport mechanism, wire frame mechanism, taper mechanism, lubrication system, etc. Machine tool bed is usually box-type structure, is to provide the installation platform of each component, and is closely related to the accuracy of the machine tool. Coordinate table is usually composed of cross drag plate, rolling guide rail, screw moving pair, gear transmission mechanism and so on. It is mainly the relative motion between the electrode wire to complete the processing of the workpiece. The wire transport mechanism is composed of a wire storage cylinder, a motor, a gear pair, a transmission mechanism, a reversing device and an insulating part, etc. The motor and the wire storage cylinder are connected and rotated to drive the electrode wire to move at a certain linear speed, and the electrode wire is neatly wound on the wire storage cylinder. The line frame is divided into single column cantilever type and double column gantry type. Single column cantilever type divided upper and lower arm, the lower arm is generally fixed, the upper arm can be lifted and moved, and the guide wheel is installed on the online frame to support the motor wire. Taper mechanism can be divided into swing type and cross drag plate structure, swing type is the upper and lower arm through the lever rotation to complete, generally used in large taper machine. The cross drag plate type is completed by moving the electrode wire to expand and expand, which is generally suitable for small taper machines. Lubrication systems are used to alleviate wear, improve mechanical efficiency, and reduce power losses. It can play the role of cooling, corrosion inhibition, vibration absorption and noise reduction.
3, electrical: stepper wire cutting machine electrical part includes machine tool circuit, pulse power supply, drive power and control system. The machine tool circuit mainly controls the operation of the wire motor and the working liquid pump, so that the electrode wire can continuously cut the workpiece. The pulse power supply provides the spark discharge energy between the electrode wire and the workpiece for cutting the workpiece. The drive power supply is also called the drive circuit, which is composed of a pulse distributor, a power amplifier circuit, a power supply circuit, a predischarge circuit and other control circuits. It is a power supply that provides power to the stepper motor and is used to control the stepper motor. The control system is mainly to control the movement of the table drag plate (trajectory control) and the discharge of the pulse power supply (machining control).
