Pure electric drive wheel belt type numerical control bending machine

Abstract

The invention mainly provides a pure electric drive wheel belt type numerical control bending machine. The pure electric drive wheel belt type numerical control bending machine comprises vertical plates which are symmetrically installed at the two sides; the opposite sides of the vertical plates which are symmetrically installed at the two sides are each provided with a sliding chute; an upper movable plate is slidably installed between the sliding chutes of the vertical plates which are symmetrically installed at the two sides; a cavity is formed inside the upper movable plate; an upper stroke plate capable of moving up and down is arranged inside the cavity; the upper stroke plate is provided with driving motor units; inside the cavity, each electromotor unit sequentially makes transmission contact with a first roller units, a second roller unit and a third roller unit through a belt; and one end of each belt extends out of the corresponding third roller unit and is slidably connected with a fourth roller unit which is fixed to the corresponding vertical plate. According to the pure electric drive wheel belt type numerical control bending machine provided by the invention, a pureelectric drive belt wheel type structure is mainly adopted for replacing the existing servo motor transmission and hydraulic transmission structures, thus the precision is improved; meanwhile the safety coefficient is increased; and the phenomenon of human injury caused by automatic drop of an upper active plate is absolutely prevented.

Description

technical field [0001] The invention mainly relates to the technical field of bending machines, in particular to a pure electric drive wheel-belt type numerical control 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. When in use, the wire is energized to the coil, and after energization, an attractive force is generated on the pressure plate, so as to realize the clamping of the thin plate between the pressure plate and the base. Due to the use of electromagnetic force clamping, the pressure plate can be made into a variety of workpiece requirements, and the workp...

Problems solved by technology

[0006] In the application document 201310059303.6, a bending machine with a new structure is proposed, which mainly adopts the structure connecting the control system and the servo motor, which reduces the operation difficulty of the bending machine and improves the precision of the bending machine to a certain extent; However, fundamentally, the safety factor of the bending machine is still low, and the operation accuracy of the bending machine has not been optimized. Moreover, the bending machine with this structure needs long-term maintenance, which increases the cost and wastes labor.
