How a bender works

The protection device of the bending machine is a kind of protective device against accidents in the process of sheet metal processing, to ensure the operation personnel of the bending machine during sheet metal processing, to avoid the occurrence of pressing accidents. 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. In the technical field of CNC sheet bending machine, the research and application of real-time intelligent control are developing along the following aspects: adaptive control, trance control, neural network control, expert control, learning control, feedforward control and so on. Because numerical control sheet material bending machine used electromagnetic force clamping, so that the pressure plate can be made into a variety of workpiece requirements, and can be processed on the side wall of the workpiece, the operation is also very simple.

Working principle of hydraulic bending machine: the rear baffle plate is first moved to a certain position. When the feeding mechanism moves the plate to contact with the baffle plate, the hydraulic cylinder drives the slider and drives the upper die downward. According to the required bending Angle, the slider drives the upper die down to the depth of the lower die, resulting in sheet metal forming and then fast return. Among them, the moving position of the slider of the hydraulic bending machine is read out by the measuring device at both ends -- the grating ruler at any time and compared with the required position. The oil intake of the cylinder is adjusted according to the position deviation, so as to ensure the synchronization accuracy and positioning accuracy of the slider in the process of movement.

Bending machine features:

1、 The bending times of the current working step are completed. When the trip switch is encountered, the position of horizontal block is adjusted automatically.

2、All work steps are completed. When the trip switch is hit, the continuous bending action of CNC sheet bending machine ends. 

3、Set the pressure holding time, pressure relief time, the distance between the advance and retreat of horizontal stopper, adjust the position of horizontal stopper of CNC sheet bending machine.

4、 Set the number of CNC bending machine steps and each step of the position of the block, bending tension.

5、 Select the continuous operation gear, and press the bending mechanism is not in the upstroke switch position. First, automatically return to the upstroke switch position; Step on the foot slowly forward, press down bending mechanism automatically press down; When the trip switch is touched, the horizontal baffle mechanism will go back to set the distance and maintain the pressure automatically. CNC sheet bending machine pressure holding time to the automatic unloading, the unloading time to the down bending mechanism automatically return, at the same time, the horizontal blocking mechanism automatically forward set distance; Hit the trip switch, a bending action ends, the next bending.
