In the bending process of the bending machine, the pressure between the upper die and the lower die is not the pressure, and the desired bending angle is obtained by adjusting the die depth of the die. This bending manner is called a bending gap. Into the mold die, bending machine bending angle is small, the greater, and vice versa. Due to the elastic material, there is also a need to consider when controlling the amount of rebound and excessive bending of the bend, the advantage of the bend gap is that you can use a smaller number of dies, achieve multiple forming angles, required handling and less stress. In general, to obtain the best bending effect, the ratio of the material thickness T and V to the width of the V-shaped opening under mold is based on T:1:8V:
Hydraulic bending machine operation should pay attention to the following points:
1. After the weak point is pressurized in this process, the drop will stop automatically, and the pressure or slowing down will not slow down or increase.
2, automatically stop when the pressure; increase is normal, not a rapid decline, but the normal pressure of the product.
3, when the high and low voltage products. Sometimes it's half normal, sometimes it's not half normal. But when it is normal, the two sides are not normal. The two sides are normal and not normal.
Hydraulic bending machine introduction and operation need to pay attention to what matters
The hydraulic bending machine includes a bracket, a worktable and a clamping plate. The worktable is placed on a bracket. The workbench is composed of a base and a pressure plate. The base is connected to the clamping plate through a hinge. The base is composed of a seat shell, a coil and a cover plate. Placed in the recess of the seat shell, the top of the recess is covered with a cover plate. In use, the coil is energized by the wire, and after the power is applied, a force is generated on the pressure plate, thereby clamping the thin plate between the pressure plate and the base. Due to the use of electromagnetic force clamping, the pressure plate can be made into a variety of workpiece requirements, and the workpiece with sidewalls can be processed.
