Large plate double linkage bending machine

Abstract

Disclosed is a large-sized plate material double linkage bending machine, comprising a workbench (1), a PLC control device (2), a mold base (3), a left bending apparatus (4), and a right bending apparatus (5). The workbench (1) comprises a front transverse beam (11), a rear transverse bean (12), and at least two guiding columns (13). The at least two guiding columns (13) are fixed in parallel between the front transverse beam (11) and the rear transverse beam (12). A mold base track (6) also is fixed at the center position of several guiding columns (13). Several molds of different shapes and structures are connected in series on the mold base track (6). The double linkage bending machine is primarily applicable in the bending of large-sized plate materials, when bending, the positions of upper and lower molds of the machine allow the relative distance from each other to be adjusted by adjusting a sliding track, thus making use convenient. Left and right molds (21 and 22) are removable, thus further facilitating replacement. The machine is applicable in a range of processing and also in processing the bending of a small-sized part.

[0002] In the prior art, the length of the bending sheet is often greater than the width of a single bending machine. In order to bend such an ultra-long sheet, it is necessary to carry out a double-machine linkage operation, that is, splicing two bending machines together, and making them It works synchronously. This kind of bending machine can be called a double-machine linkage bending machine. It mainly includes the first bending machine and the second bending machine. Each bending machine is equipped with a workbench. The lower mold is fixed, and the two ends of each bending machine are equipped with side plates. The two ends of the workbench and the lower mold are flush with the outer sides of the corresponding side plates. , there is inevitably a gap between the first bending machine and the second bending machine, so that the gap between the worktable and the lower die on the first bending machine and the worktable and lower die on the second bending machine is 3-5mm, when the two-machine linkage bends the sheet, a discontinuous crease will be formed at the joint of the lower die, resulting in poor bending accuracy of the sheet

[0003] And the existing bending parts, especially large bending parts, due to their large size, the inspection process after processing needs to complete the inspection of various angles and size data, which is difficult and time-consuming

[0004] In the existing technology, when bending large-sized sheet metal parts, due to their complex design structure, multi-pass bending is usually required, and each bending requires positioning, transportation, calibration, queuing and other processes , the processing cycle is long, and the structure and process are complicated, which is not conducive to production
