Bending system and method with detection feedback function and phased bending function

Abstract

The invention relates to a bending system and method with the detection feedback function and the phased bending function. The system comprises a driving motor arranged on a rack, a clamping and fixing base and a main machine. A bending shaft is installed on the driving motor. A machined workpiece is installed on the clamping and fixing base. The system further comprises a capacitance induction thickness detector, a pressure sensor, a proximity switch, a detection feedback device and a controller. The pressure sensor and the proximity switch are installed on the bending side of the machined workpiece. The detection feedback device comprises an ultrasonic crack detector installed on the clamping and fixing base. The capacitance induction thickness detector, the pressure sensor, the proximity switch and the ultrasonic crack detector are all connected with the main machine through a DSP data processing module. According to the system, the crack proportion is greatly reduced due to crack detection and phased bending, and machining quality is improved. The proximity switch is arranged to automatically control the bending angle so that excessive bending can be prevented, besides, the height and the angle can be conveniently adjusted due to the proximity switch, and the system can adapt to bending of multi-size and multi-angle sheet metal.

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 hydraulics. 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 realize sim...

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 crack defects 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; The angle control device is prone to excessive bending and poses safety hazards
