Metal plate bending machining device and method

Abstract

The invention relates to a metal plate bending machining device and method. The metal plate bending machining device comprises a driving motor arranged on a rack, a clamping fixing base and a main machine; a bending shaft is installed on the driving motor, and a machined piece is arranged on the clamping fixing base; the device further comprises an ultrasonic wave thickness detecting device installed on the rack depending on a support, a pressure sensor installed on the clamping fixing base, a proximity switch, a rolling shaft and a controller connected with the main machine; the ultrasonic wave thickness detecting device, the pressure sensor and the proximity switch are each connected with the main machine through a DSP data processing module. According to the metal plate bending machining device and method, staged bending is achieved, so that the crack number is greatly decreased, and the machining quality is improved; the rolling shaft is arranged to extrude and rub the internal concave face of the machined piece, so that protruding burrs and cracks are effectively removed, the follow-up machining process is saved, and the machining period is shortened; the proximity switch for controlling the bending angle is arranged, so that excessive bending is prevented.

Description

technical field [0001] The invention relates to the technical field of sheet metal processing, in particular to a sheet metal bending device. Background technique [0002] Currently used sheet metal bending machine, commonly used two types of organic pillow hydraulic, mechanical bending machine is to use the motor through a series of gear transmission and eccentric wheel to realize the up and down movement of the working joint. The hydraulic bending machine is realized by using a hydraulic cylinder and a complete set of oil circuit control components. These bending machines play an important role in the mass production of large enterprises, but due to their high price and complex structure, their popularization is limited. With the development of the commodity economy, there are more and more stamping parts for small commodities for daily use. Small enterprises and even self-employed households urgently need sheet metal bending machines with low price and simple structure. ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are some small bending machines on the market. When working, the bending torque is set by the experience of the workers. It cannot be adjusted in real time with the thickness of the plate, and the constant bending force cannot be changed with the change of the bending angle. The bending effect is not good, and there are crack defects in the bent plate; there are burrs and cracks in the concave surface of the bent plate due to material extrusion, and further processing is required, and the processing cycle is long; the lack of angle control device is easy to appear Excessive bending poses a safety hazard
