Sheet metal bending device based on bending angle control and feedback torque adjustment

Abstract

The invention relates to a sheet metal bending device based on bending angle control and feedback torque adjustment. The sheet metal bending device based on bending angle control and feedback torque adjustment comprises a drive motor, a clamping fixing base and a host which are arranged on a machine frame; a bending shaft is installed on the drive motor; the clamping fixing base is provided with a processed workpiece. The sheet metal bending device based on bending angle control and feedback torque adjustment further comprises an ultrasonic thickness detector, an ultrasonic crack detector, a pressure sensor, a roller, a proximity switch and a controller connected with the host, wherein the ultrasonic thickness detector, the ultrasonic crack detector, the pressure sensor and the roller are installed on the machine frame; the ultrasonic thickness detector, the ultrasonic crack detector, the pressure sensor and the proximity switch are connected with the host through a DSP data processing module. Through combination of staged type bending and feedback control, the crack quantity is greatly reduced, and the processing quality is improved; the arranged roller carries out extrusion and friction on the concave surface of the processed workpiece, effectively removes protrusive burrs and cracks and omits the subsequent processing process; the proximity switch controls the bending angle, so that excessive bending is prevented, and the processing safety 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] The currently used sheet metal bending machines are of two types: organic pillow hydraulic pressure. The mechanical bending machine uses a motor to move up and down through a series of gear shifts and eccentric wheels. The hydraulic bending machine is realized by using hydraulic cylinders and a set of oil circuit control components. These bending machines play an important role in the mass production of large enterprises, but Bi Jing's high price and complex structure limit its popularity. With the development of the commodity economy, daily-use small commodity stamping parts are increasing day by day. Small businesses and even self-employed households urgently need low-priced, simple-structured sheet metal bending machines. [0003] At present, there are some small bending machines on the market, which can rea...

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; Later, due to cracks and burrs on the concave surface of the sheet material, further processing is required, resulting in a long processing cycle; lack of angle control devices, prone to excessive bending, posing safety hazards
