Problems solved by technology

[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

Abstract

The invention discloses a double-linkage bending machine allowing molds to be rapidly replaced and used for large panels. The double-linkage bending machine comprises a worktable, a PLC control device, a mold base, a left bending device and a right bending device. The worktable comprises a front beam, a rear beam and at least two guide columns. The at least two guide columns are fixed between the front beam and the rear beam in parallel. A mold base rail is further fixed to the middle positions of the multiple guide columns. Molds of different shapes and structures are sequentially connected to the mold base rail. The left mold and the right mold of the mold base rail of the bending machine are directly connected to the mold base rail through sliding trolleys correspondingly, and meanwhile the sliding trolleys are fixed to the left bending device and the right bending device through connection rods correspondingly. The bending machine is compact in structure, suitable for bending multiple structures of the large panels and capable of rapidly unloading and unloading bent parts, and the bending machine can also conduct two-side same-time bending for large-width bending machines.
