punch machine hydraulic cylinder are widely used in Algeria，because of long service life，smooth movement，high work efficiency.So our company has designed punch machine hydraulic cylinder for customers from Algeria.

Introduction to punch machine hydraulic cylinder:

The definition of the minimum starting pressure of the punch machine hydraulic cylinder refers to the minimum working pressure of the punch machine hydraulic cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the punch machine hydraulic cylinder parts and the size of the sealing friction.

The machining accuracy of the punch machine hydraulic cylinder depends on the level of equipment, production technology and testing means. punch machine hydraulic cylinder processing methods are commonly used in two ways, one is rough boring - fine boring - rolling, generally with 45# seamless steel pipe, this method of processing quality is good, but the cost is high. Another method is to use 20# cold-drawn seamless steel pipe, and then honing, the cost is lower. The piston rod must be adjusted and straightened before processing, and the coating thickness of the piston rod is generally not less than 0.03mm. The piston must be machined in strict accordance with the groove size and tolerance requirements given in the seal manual.

If the punch machine hydraulic cylinder operation failure, you can start from these aspects to troubleshoot: (1) the hydraulic system control pressure is too low. The throttling resistance in the control line may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is disturbed. At this time, the control pressure source should be checked to ensure that the pressure is adjusted to the specified value of the system; (2) Air enters the hydraulic system. Mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced. (3) The initial action of the punch machine hydraulic cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow punch machine hydraulic cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the punch machine hydraulic cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the punch machine hydraulic cylinder includes the leakage caused by excessive wear of the punch machine hydraulic cylinder block seal, the piston rod and the seal cover seal and the piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time. The main cause of excessive piston seal wear is improper adjustment of the speed control valve, resulting in excessive back pressure and improper seal installation or hydraulic oil contamination. The second is that foreign bodies enter the assembly and the quality of sealing materials is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and punch machine hydraulic cylinder, and the phenomenon of "pulling the punch machine hydraulic cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.

The punch machine hydraulic cylinder is mainly composed of body, piston, piston rod, punch machine hydraulic cylinder head, punch machine hydraulic cylinder bottom, piston rod head and related auxiliary devices. The piston divides the punch machine hydraulic cylinder into two chambers, and moves reciprocally in the punch machine hydraulic cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the punch machine hydraulic cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the punch machine hydraulic cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the punch machine hydraulic cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the punch machine hydraulic cylinder bottom and the punch machine hydraulic cylinder head is serious, so the buffer deceleration should be set at both ends of the punch machine hydraulic cylinder The working medium of the punch machine hydraulic cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; punch machine hydraulic cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the punch machine hydraulic cylinder: The buffer structure of the punch machine hydraulic cylinder is to prevent the piston from colliding with the punch machine hydraulic cylinder head at the end of the stroke.

Answers to some questions about punch machine hydraulic cylinder:

PLC+ inverter + motor + pump + solenoid valve + cylinder combination, can control the accuracy of cylinder position?
In the case of extremely high accuracy requirements, you can not, please consider a few problems: 1, hydraulic oil can be compressed, it is elastic like a spring. Therefore, in the general hydraulic servo system, the valve control is far more accurate than the pump control. Because the valve can be installed very close to the hydraulic cylinder, or even installed on the hydraulic cylinder, but the pump must go through the tubing and then into the hydraulic cylinder, there is a long distance, which greatly reduces the rigidity of the system and increases the difficulty of control. 2, the quantitative pump is first of all leaking, and there is 10%-20% flow pulsation. Secondly, and more unfortunately, the leakage of the pump is related to the pressure and is non-linear.

What is the role of the cylinder on the plastic mold? The oil cylinder plays a great role in the mold, one is that the core distance is very large, or because of the mechanism of the product, only the oil cylinder is reasonable or more cost saving. Let the side core be extracted before opening the mold. Hot runner is mainly based on the product, sometimes customers require to use hot runner, the price is more expensive, but there are many benefits. It can save raw materials and shorten the molding cycle.
