Bending device

Abstract

A bending device (1) has ram start-up means (2) provided so as to be movable in the left-right direction and has control means (20E) for moving the ram start-up means (2) to in front of a work positioning position at each bending. In another example, the bending device (1) has the ram start-up means (2) provided so as to be movable in the left-right direction, foreign object detecting means (8, 9) for detecting the entry of a foreign object into the region of movement of the ram start-up means (2), and the control means (20E) not permitting the ram start-up means (2) to move when the entry of a foreign object is detected.

Description

technical field [0001] The present invention relates to a bending processing device having a foot switch capable of moving to the front of a workpiece positioning position in each bending sequence in step bending processing. Background technique [0002] Conventionally, bending processing devices, such as press brakes, determine the bending sequence (manually or automatically) by sequentially selecting bending lines according to product information. Moreover, after determining the mold and mold layout (processing station) in each bending sequence, according to the determined mold layout, after setting the specified mold on the specified position of the upper and lower worktables, the slide in the upper and lower worktables is activated by turning on the foot switch. The block starts to bend the workpiece. [0003] In this kind of bending processing equipment, along with the complexity of products, multiple processing stations are installed for multiple processing. In each b...

Problems solved by technology

[0005] However, in the step-by-step bending process, for a workpiece that is the processing object, the bending line may exist at the end of the workpiece in the left and right direction. The front of the center point moves, and the distance between the actual processing position (the end of the workpiece in the left and right direction) and the foot switch becomes larger

[0006] Therefore, the operator has to adopt an unnatural posture, and the operation is very difficult to carry out, so that the operation efficiency is low. In addition, the contact accuracy of the workpiece, which indicates the degree of proper contact state between the workpiece and the striker, is low, and it is impossible to obtain a high-precision flange size

[0007] On the other hand, in the prior art, if one process (bending sequence) ends, the foot switch starts to move towards the next processing station, but at this time, for example, the operator steps his foot on the foot switch on, and during the movement of the foot switch, part of the operator's body will enter the movement area

[0008] Therefore, the operator is in an extremely dangerous state, and safety cannot be ensured, and a major accident may occur
