Abstract

The invention belongs to the technical field of bending machines, particularly relates to a forward holding bending device for a bending machine. By aiming at the problem that existing spiral workpieces are low in machining efficiency, the following scheme is provided, wherein the forward holding bending device comprises a workbench, a guide rod is fixed to the front ends of bending cylinders, a guide groove is formed in the guide rod in a penetrating manner, a guide screw is rotationally connected in the guide groove, a lantern ring is fixed to the top of a guide block, an outer rod is fixed to one side of the lantern ring, an inner rod is arranged on the other side of the outer rod, an electromagnet is fixed to the other side of the inner rod, a first sliding groove is formed in the top of a first fixed plate, a first sliding block is slidably connected in the first sliding groove, a first spring is fixed between the first sliding block and the first sliding groove, and a second fixed plate is fixed to the top of the first sliding block. In the device, an electromagnet generates attraction force to the insertion end of a workpiece, the bending cylinders rotate and meanwhile drive the electromagnet to rotate, so that the electromagnet moves synchronously along with the workpiece, and one end of the workpiece is pulled towards the front end through the attraction force, so that the workpiece is gradually in a spiral shape.

Description

technical field [0001] The invention relates to the technical field of bending machines, in particular to a front support bending device for a bending machine. Background technique [0002] The bending machine is a machine capable of bending thin plates. Its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench is composed of a base and a pressure plate. The base is composed 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. The pressure plate can be made into various workpiece requirements, and can process workpieces with side walls. It is also very simple. [0003] Due to the needs of development, the shape requirements of the workpiece are diversified, and the bending machine has also been continuously developed. The bending device is an indispensable part of the bending machine, but the existi...
