Bending machine mold in actual use need to pay attention to: 1, bending machine die 88° why can press out 90°. Because the metal plate has a certain elasticity, ordinary cold rolled plate mold Angle 88° can be, but stainless steel only needs 86°, some elastic only 83° on the line, aluminum hardness is low, elasticity is small, the mold Angle must be 90°, so do you understand, in addition, the Angle of the mold is mainly determined by the… Read More »How to choose CNC bending machine die and use process need to pay attention to a few points?

 1. First turn on the power supply of 160 tons 4 meters hydraulic bending machine (160T/4000), turn on the button switch on the control panel, and then press the oil pump to start, so that you can hear the rotating sound of the oil pump. (The machine does not move at this time) 2, stroke adjustment, 160 tons 4 meters hydraulic bending machine (160T/4000) must pay attention to adjust the stroke, bending must be tested. At the bottom of the… Read More »160 tons 4 meters hydraulic bending machine (160T/4000) operation method

The electro-hydraulic control system in the wc67y hydraulic press brake can be divided into open loop control system and closed loop control system. The beam of the bending machine is the main control part of the system. 1. The closed loop The closed loop is also known as a feedback control system. The system compares the measured value of the system output with the expected given value, so as to produce the deviation signal, and then uses the signal deviation… Read More »What is the main control part of the wc67y hydraulic press brake?

CNC bending machine has been widely used, but the price is also different, in addition to related to hardware and specification, CNC bending machine much more compared to ordinary bending machine CNC system is an important point of comparison, the different types of numerical control system, can also lead to the price of CNC bending machine, today we take a look at what CNC system is the classification of CNC bending machine? First we need to know what is a… Read More »What are the classification of CNC bending machine CNC system?

CNC bending machine price  die in order to get long life, in the bending process should be as long as possible to adhere to continuous cutting. If the bending machine die enters and exits too frequently, the bending machine die life will be significantly shortened. This will increase thermal stress and thermal fatigue on the cutting edge. A uniform and high temperature in the cutting area is more favorable to modern carbide bending machine dies than a large shake. The… Read More »CNC bending machine price: how to extend the life of the bending machine

The principle of choosing hydraulic pump of bending sheet metal Whether variable: radial piston pump, axial piston pump, single acting vane pump is variable pump. Bending machine working pressure: piston pump pressure 31.5mpa; Vane pump pressure 6.3MPa, high pressure can reach 21MPa; Gear pump pressure 2.5mpa, high pressure after up to 25MPa. Working environment: gear pump has the best anti-pollution ability. Noise index: low noise pump internal gear pump, double acting vane pump and screw pump, double acting vane pump… Read More »A machine capable of bending sheet metal

Hydraulic bending machine is a kind of can be carried out on the thin plate bending machine, the structure mainly includes the bracket, workbench and clamping plate, workbench on the scaffold, workbench consists of base and the clamp, the base through the hinge is connected with the clamping plate, the base is composed of shell, the coil and plate, coil placed inside the shell of the sag, the depression at the top of the cover plate. When used, the wire… Read More »Hydraulic bending machine according to the way of movement can be divided into: moving up, moving down
