A horizontal double linkage bending machine

Abstract

The invention discloses a horizontal double-linkage bending machine. The machine comprises a worktable, a PLC device, a die seat, a left bending device and a right bending device, wherein the worktable comprises a front cross beam, a rear cross beam, and at least two guide columns which are fixed in parallel between the front cross beam and the rear cross beam; a die seat rail is fixed among the plurality of guide columns; a plurality of dies with different shape and structure are sequentially connected to the die seat rail; at least one compressing device is arranged at each of the left side and the right side of the die seat rail, and each compressing device is connected to the front cross beam or the rear cross beam through a cantilever, a telescoping compressing shaft and a telescoping power source; the left bending device and the right bending device are correspondingly driven through a left sliding device and a right sliding device to move toward the die seat rail; a left bending servo power source and a right bending servo power source are synchronously connected to the PLC device so as to coordinately control the bending. The horizontal double-linkage bending machine is a double-linkage bending machine which is compact in structure, efficient in bending and applicable to wide boards.

Description

technical field [0001] The invention relates to the technical field of plate bending equipment, in particular to a horizontal double linkage bending machine. Background technique [0002] In the prior art, the length of the bending sheet is often greater than the width of a single bending machine.

[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
