Sheet metal machining device based on torque adjustment and multi-point pressure detection

Abstract

The invention relates to a sheet metal machining device based on torque adjustment and multi-point pressure detection. The sheet metal machining device comprises a driving motor arranged on a rack, a clamping fixing base and a host for controlling the driving motor; a bending shaft is installed on the driving motor, and a machined workpiece is arranged on the clamping fixing base; the sheet metal machining device further comprises a capacitive sensing thickness detector installed on the rack through a support, a supporting rod installed on the clamping fixing base, a pressure sensor installed on the clamping fixing base and a controller connected with the host; the supporting rod is arranged in a clamping groove of the clamping fixing base, a proximity switch is connected to the upper end of the supporting rod, and the pressure sensor device is arranged on the side face of the machined workpiece; the capacitive sensing thickness detector, the pressure sensor and the proximity switch are connected with the host through a DSP data processing module; and pressing plates are symmetrically arranged on the inner side wall of a clamping groove, each pressing plate is evenly provided with a plurality of pressure detection points, and the pressure detection points are connected with the pressure sensor.

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. ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are some small bending machines on the market. The bending torque is set by the experience of the workers when working, and it cannot be adjusted in real time according to the thickness of the sheet. Therefore, the processing quality of the sheet is not high, and there are crack defects in the sheet after bending; there is a lack of angle control. device, it is prone to excessive bending, and there are safety hazards; the clamping part of the workpiece is prone to excessive deformation or loosening
