Hoisted feeding device for horizontal double-linkage bending machine

Abstract

The invention discloses a hoisted feeding device for a horizontal double-linkage bending machine. The hoisted feeding device is used by being connected to the double-linkage bending machine with a workbench, a PLC device, a mould base, a left bending device and a right bending device. The hoisted feeding device is arranged over the workbench and the mould base and comprises a conveying platform and a robot crane jib, and the robot crane jib conveys plates prepared on the conveying platform to the top of the mould base through a plurality of grippers arranged at the bottom of the robot crane jib; a plurality of pneumatic compressing devices are arranged on the tops of the grippers of the robot crane jib and connected with the PLC device to achieve synchronous coordinative control; the end, close to the workbench, of the conveying platform is provided with a flexible material blocking plate, and the flexible material blocking plate is of a half-I-shaped structure. According to the hoisted feeding device special for the horizontal double-linkage bending machine, the dual functions of hoisted feeding and compressing bending are achieved.

Description

technical field [0001] The invention relates to the technical field of plate bending equipment, in particular to a hanging feeding device for 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. 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...

[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
