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 and screw pump instantaneous flow uniform.
Efficiency: the total efficiency of the axial piston pump is the highest; The same structure of the pump, the total efficiency of the pump with large displacement.
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. Next xiaobian to introduce you to the adjustment of bending machine pin distance, I hope it will be helpful to you!
1. Loosen the upper and lower forming knife pressure plate, adjust the screw, adjust the upper forming knife to the required distance, and set the pressure plate;
2, adjust the helicobacter, so that the upper and lower forming knife to reach the required gap;
3, pay attention to the adjustment of the next forming knife to keep parallel to each other;
4. Adjust the handwheel 39 so that it is appropriate to form the contour of the anchor. The distance of wire feeding becomes shorter up, and longer on the contrary.
