Easily mounted/dismounted limiting device for numerically-controlled bending machine

Abstract

The invention relates to the technical field of forging technology, in particular to an easily mounted/dismounted limiting device for a numerically-controlled bending machine. The limiting device comprises a main base, a main frame and a hydraulic oil cylinder, wherein the lower end of the hydraulic oil cylinder is connected with a hydraulic sliding block; the lower end of the hydraulic sliding block is detachably connected with an upper die of the bending machine; and a fixing groove is formed in the upper surface of the main base and located at a position corresponding to the upper die of the bending machine. According to the easily mounted/dismounted limiting device for the numerically-controlled bending machine, an adjusting limiting groove, in which limiting blocks are arranged, is formed in the upper surface of the main base and located at a position near a lower die of the bending machine, and the positions and angles of limiting plates can be freely changed by changing the angles of the limiting blocks, so that the limiting plates can not only be placed in accommodating grooves to form a flat surface and but also be erected to form rear baffles and side baffles, thus greatly enlarging the application range of the limiting device; and by virtue of elastic pressing rods in the limiting blocks, the connection stability of the limiting blocks is greatly improved to improve the assembly firmness.

Description

technical field [0001] The invention relates to the technical field of forging, in particular to an easy-to-install and dismount limiting device for a numerically controlled bending machine. Background technique [0002] The CNC bending machine controls the up and down movement of the oil cylinder through the CNC system, thereby driving the mold installed on the slider to move up and down, and squeezes with the lower mold installed on the workbench to realize the bending of the workpiece. During the bending process, the position of the workpiece is mainly adjusted and fixed manually, which is not only time-consuming and laborious, but also the instability of manual operation can easily affect the bending position and accuracy of the workpiece, and it is currently used on the rear side of the bending machine The loading and unloading of the limit device is troublesome, the cost is high, and the operation method is also inconvenient.

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in order to solve the problems existing in the above-mentioned background technology, an improved easy-to-load and disassemble limit device for CNC bending machines is provided, which solves the problem that the current workpiece placement is mainly done by manually adjusting the position of the workpiece. Adjusting and fixing is not only time-consuming and laborious, but also the instability of manual operation can easily affect the bending position and accuracy of the workpiece, and the rear side limit device currently used for bending machines is troublesome to install and disassemble, the cost is high, and the operation method is not good.
