Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to a bracket for bending machines. Background Art

[0002] A bending machine is a machine that can bend thin plates. Its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench consists of a base and a pressure plate. The base is connected to the clamping plate by a hinge. The base consists of a seat shell, a coil and a cover plate. The coil is placed in the depression of the seat shell, and the top of the depression is covered with a cover plate.

[0003] When the existing bending machine is bending the plate, the two sides of the plate will be forced to warp up. After the plate is bent, due to the warping of the two sides of the plate and the retraction of the bending head of the bending machine, the two sides of the plate are not well supported, and it is easy to fall over, causing the plate to collide with the workbench, which not only affects the production quality of the plate, but also makes it inconvenient to unload the plate, affecting the production efficiency of the device. In summary, the existing bending machine still has the following problems:

[0004] After the plate is bent, there is no good support on both sides of the plate, and it is easy to tip over, causing the plate to collide with the workbench, affecting the production quality and production efficiency of the plate. Utility Model Content

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The servo motor on the adjusting device drives the threaded rod to rotate in the slide groove. When the threaded rod rotates, it will drive the adjusting seat on its outer surface to slide back and forth in the slide groove, so that the No. 1 hydraulic cylinder on the bracket device moves accordingly and aligns it with the plate to be bent. When the plate is bent, the No. 2 hydraulic cylinder drives the limit support plate on its output end to make appropriate adjustments to limit the two sides of the plate to prevent the plate from shaking and deviating when it is bent. After the plate is bent, the No. 2 hydraulic cylinder drives the limit support plate to clamp the plate to prevent the plate from tipping over. Then the No. 1 hydraulic cylinder pushes the No. 2 hydraulic cylinder upward to move the plate out of the bending seat. At this time, the servo motor drives the threaded rod and the adjusting seat on it, so that the plate moves accordingly, which facilitates the unloading of the plate.

[0015] 2. When the plate needs to be bent, the plate can be placed on the movable shaft on the loading device, and the plate is then quickly pushed to the upper end of the bending seat through the movable shaft to facilitate the loading of the plate. BRIEF DESCRIPTION OF THE DRAWINGS
