Feedback torque adjustment and metal plate bending system

Abstract

The invention relates to a feedback torque adjustment and metal plate bending system. The feedback torque adjustment and metal plate bending system comprises a driving motor arranged on a machine frame, a clamping fixing seat and a mainframe, wherein a bending shaft is installed on the driving motor, and a machined part is arranged on the clamping fixing seat. The feedback torque adjustment and metal plate bending system further comprises an ultrasonic thickness detector, an ultrasonic crack detector, pressure sensors, a rolling shaft, a proximity switch and a controller connected with the mainframe, wherein the ultrasonic thickness detector, the ultrasonic crack detector, the pressure sensors, the rolling shaft and the proximity switch are installed on the machine frame. The ultrasonic thickness detector, the ultrasonic crack detector, the pressure sensors and the proximity switch are respectively connected with the mainframe through a DSP data processing module. Staged bending and feedback control are combined, so that crack amount is greatly decreased. The arranged rolling shaft is used for conducting extrusion and friction on the inwards concave face of the machined part, and protruding burrs and cracks are effectively removed. A bending angle is controlled through the proximity switch so as to prevent excessive bending. A clamping pressure and positioning are controlled through the pressure sensors, plate deformation or drop is avoided, and machining reliability is improved.

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. ...

Problems solved by technology

[0003] At present, some small bending machines have appeared on the market, which can realize simple bending processing of plates, but they have the following disadvantages: the bending torque is set by the experience of workers during work, and cannot be adjusted in real time with the thickness of the plate, and a constant The bending force cannot change with the change of the bending angle. The processing quality of the sheet is not high, and there are cracks in the sheet after bending; the sheet after bending can only be detected by naked eyes, which is not accurate and the effect is not good; Afterwards, due to cracks and burrs on the concave surface due to extrusion, further processing is required, resulting in a long processing cycle; the lack of angle control devices is prone to excessive bending, which poses a safety hazard; the workpiece to be processed is manually adjusted and clamped. The holding force is often too large or too small, resulting in loosening of the processed part or excessive deformation of the clamping part during bending. The processed part relies on experience to locate, the positioning is not accurate, and prone to deviation or empty folding
