CNC Hydraulic Sheet Metal Press Brake Bending & Shearing Machine

Through the specification selection, the following principles should be followed while choosing the punching machine's specification:  1, The nominal pressure of the press  punching machine  must be greater than the stamping process force. However, when it comes to the long working process of the procedure, it should not only meet the size of the craft force, but also consider to meet its workload curve .  2, The press slider stroke should be able to meet the workpiece height in the required size, and should be removed from the mold successfully after the stamping process .  3, Productivity requirements should be calculated according to its free frequency.  4. The closure height, table size, slider size, mold handle hole size must be able to meet the correct installation requirements of the molds. For crank pressure machine, the closing height of the mold should  be between the maximum mold height and the minimum mold height. The size of workbench should generally be greater than t

The upper roll of the hydraulic rolling machine is in the symmetrical direction of the two lower roller center through the hydraulic oil in the hydraulic cylinder. Through the last gear of the main reducer, the two lower roller gear rodents the cooperative rotation movement, which provides torque for the rolled sheet. Protection of hydraulic rolling machine: The maintenance of the  hydraulic rolling machine  is to refuel the oil cups and the artificial smooth points according to the requirements. After switching on the power supply, check whether all movements have normal card death. Strictly according to roll board process and operation method, we should pay attention to the safe operation of the equipment. According to the parameters of the rules of the hydraulic rolling machines, the thickness of the roll board is 20 mm and the maximum length is 2500 mm. The yield limit of coil material is less than 250 Mpa. In the process of operation, if irregular noise, impact and other abnormal

Before you are going to purchase a hydraulic shearing machine, come and check these five factors. We hope they are useful for your manufacturing. 1. According to the requirements of the factory, it is necessary to decide the shearing machine sizes that you need. Generally speaking, the sizes are depending on the the shape sizes, processing tonnage. And to buy the shearing machine, you can also care about the systems used. For the  hydraulic shearing machine , after the machine tool model is determined, or contact our technicians and understand how to choose the model, then place your order. 2. To know the manufacturers that produce shearing machines, and this process is often easy to be ignored. In fact, different manufacturers basically produce different machine tools, so you'd better choose the best professional manufacturer specialized in producing shearing machines. If you are going to choose from China hydraulic shearing machine manufacturers, first of all, it must be a fac

If the  hydraulic shearing machines  are used for long periods of time, there will be some failures. How should we diagnose the failure of the hydraulic shearing machine during daily use? Diagnostic methods for common faults The CNC hydraulic shearing machine is composed of mechanical, hydraulic, electrical and other devices, so there are many kinds of failures. A certain fault phenomenon may be caused by many factors. As a result, to analyze hydraulic failure, we must be able to understand the schematic diagram of hydraulic system and have a general understanding of the function of each element in the schematic diagram, then we can analyze and judge according to the fault phenomenon. It is difficult to understand the situation of working fluid in the hydraulic system. Therefore, it brings more difficulties for the analysis and diagnosis, so it is required that people have the ability to analyze and judge faults. It is necessary to find the failure cause in the complicated relationshi
