Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to a hydraulic plate bending machine for facilitating the fixation of workpieces. Background Technique

[0002] A bending machine is a machine that can bend thin plates. During the use of the bending machine, the thin plate to be bent is placed on the workbench, and the bending upper die moves downward to bend the thin plate together with the bending lower die.

[0003] When the existing hydraulic plate bending machine is in use, it is not convenient to quickly place and position the plate. When placing the plate, it is necessary to first mark a marking line at the bending position of the plate, and then align the marking line with the bending lower die to position the plate. This not only has cumbersome operations, low work efficiency, but also is prone to deviation during placement, resulting in inaccurate bending positions and defective products. For this reason, we propose a hydraulic plate bending machine for facilitating the fixation of workpieces to solve the above-mentioned problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a hydraulic plate bending machine for facilitating the fixation of workpieces to solve the problems raised in the above background technique.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. The present utility model can position and fix the stock plate when the stock plate is placed through the two positioning plates provided. It only needs to place the stock plate between the two positioning plates. During the bending process of the stock plate, if the stock plate tilts, it will squeeze the positioning plates.
