Sectional type bending device with capacitive thickness detecting function

Abstract

The invention relates to a sectional type bending device with a capacitive thickness detecting function. The sectional type bending device with the capacitive thickness detecting function comprises a driving motor, a clamping fixing seat, a main body, a capacitive sensing thickness detector, a pressure sensor, a proximity switch, a detecting feedback device and a controller, wherein the driving motor, the clamping fixing seat and the main body are arranged on a rack; a bending shaft is mounted on the driving motor; a machined piece is arranged on the clamping fixing seat; the pressure sensor and the proximity switch are arranged on a bent side of the machined piece; the detecting feedback device comprises an ultrasonic crack detector arranged on the clamping fixing seat; and the capacitive sensing thickness detector, the pressure sensor, the proximity switch and the ultrasonic crack detector are respectively connected with the main body through DSP data processing modules. By crack detecting and sectional bending, the proportion of cracks is greatly reduced, and machining quality is improved; and the bending angle is automatically controlled by the proximity switch, excessive bending is prevented, the height and the angle of the proximity switch can be adjusted conveniently, and therefore, the sectional type bending device is suitable for bending multi-size and multi-angle sheet metal parts.

Description

technical field [0001] The invention relates to the field of mechanical processing equipment, in particular to bending equipment. 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. [0003] At...

AI Technical Summary

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 speed is set by the experience of workers during work, and it cannot be adjusted in real time according to 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
