hydraulic sheet bending machine equipment structure

1.Hydraulic sheet bending machine equipment appearance see Figure 1, its structure is mainly composed of frame, foot switch, bending Angle positioning mechanism, horizontal retaining gear positioning mechanism, bending mechanism and electrical control system.

Bending Angle positioning mechanism is composed of servo motor and chain drive mechanism, which can be adjusted or automatically adjusted according to the set bending Angle to ensure the accuracy of height positioning. The horizontal stopper mechanism is composed of servo motor and screw drive mechanism. It can position the width of the bending workpiece by fine tuning and automatic positioning. In continuous bending, multi-step automatic selection can be carried out to achieve positioning and bending of multiple positions in turn. The bending under pressure is carried out by hydraulic mechanism, and can be carried out under three working conditions of point movement, single operation and continuous operation with foot switch.

2 Hydraulic sheet bending machine working process

The working process of the bending machine can be divided into three working modes: point, single and continuous.

Click: select the click operation gear, step down the foot slowly, press down the bending mechanism automatically press down, touch the travel switch to stop pressing down; In the process of pressing down, the foot is loose and the foot moves slowly, stopping at the current operating position; Press down the process step down the foot return, press down the bending mechanism automatically return, hit the trip stop return; During the return journey, release the foot and stop in the current return journey position.

Single time: set the pressure holding time, pressure relief time, horizontal stopper into, back distance, adjust the horizontal stopper position; Select the single operation gear, the lower pressure bending mechanism is not in the upper travel switch position, first automatically back to the upper travel switch position; Step down the pedal slowly, press down the bending mechanism automatically press down; When the stroke switch is touched, the horizontal stopper mechanism sets the distance backward and automatically maintains the pressure; Pressure holding time to automatic pressure relief, pressure relief time to lower pressure bending mechanism automatic return, at the same time, the horizontal stopper mechanism automatic forward setting distance; Touch the travel switch, the end of a single bending action.

Continuous (working step) :

(1) Set the pressure holding time, pressure relief time, the advance and retreat distance of the horizontal baffle, adjust the position of the horizontal baffle;

(2) set the number of work steps and the stopper position of each work step and the number of bending sheets;

(3) Select the continuous operation gear, the lower pressure bending mechanism will automatically return to the upper travel switch position if it is not in the upper travel switch position; Step down the pedal slowly, press down the bending mechanism automatically press down; When the stroke switch is touched, the horizontal stopper mechanism sets the distance backward and automatically maintains the pressure; Pressure holding time to automatic pressure relief, pressure relief time to lower pressure bending mechanism automatic return, at the same time, the horizontal stopper mechanism automatic forward setting distance; Touch the travel switch, the end of a bending action, the next bending.

(4) When the bending times of the current working step are completed, touch the travel switch, the position of the horizontal stopper will be adjusted automatically and enter the bending action of the next working step.

(5) All work steps are completed, touch the travel switch, the continuous bending action is finished.
