Bending device and method based on pressure detection and roll finishing

Abstract

The invention relates to a bending device and method based on pressure detection and roll finishing. The device comprises a driving motor arranged on a machine frame, a clamping and fixing base, and a main unit controlling the driving motor, wherein a bending shaft is installed on a motor shaft of the driving motor, and a part to be machined is arranged on the clamping and fixing base. The device further comprises a capacitive sensing thickness detector installed on the machine frame through a support, a first pressure sensor, a second pressure sensor, a third pressure sensor, a roller, and a controller connected with the main unit, wherein the first pressure sensor, the second pressure sensor, the third pressure sensor and the roller are installed on the clamping and fixing base, and the capacitive sensing thickness detector, the first pressure sensor, the second pressure sensor and the third pressure sensor are all connected with the main unit through a DSP data processing module. By means of staged bending, the number of cracks is reduced greatly, and machining quality is improved. The roller is arranged for extrusion friction of the inward-concave surface of the part to be machined, protruding burrs and cracks are effectively removed, subsequent processing is omitted, and process cycle is shortened.

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. The bending t...

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; the concave surface of the bent plate has burrs and cracks due to material extrusion, and further processing is required, and the processing cycle is long; the processed parts are processed manually according to experience Clamping and clamping, inaccurate clamping force will easily lead to excessive deformation or loosening of the plate, inaccurate positioning of the workpiece, prone to bending deviation or empty bending, and low processing reliability
