Sheet metal bending device and method with torque regulating function and rolling bending function

Abstract

The invention relates to a sheet metal bending device and method with the torque regulating function and the rolling bending function. The device comprises a driving motor arranged on a rack, a clamping and fixing base and a main machine. A bending shaft is installed on a motor shaft of the driving motor. A machined workpiece is installed on the clamping and fixing base. The device further comprises an ultrasonic thickness detector installed on the rack through a support, a supporting rod installed in a clamping groove of the clamping and fixing base, a rolling shaft installed on the clamping and fixing base and located on the concave face side of the machined workpiece, and a controller connected with the main machine. The upper end of the supporting rod is connected with a proximity switch. The rolling shaft is rotationally connected to the upper end face of an adjusting plate, and the lower end face of the adjusting plate is installed in an installing groove of the clamping and fixing base through a rotating shaft and a spring. According to the device, bending is performed at the optimum torque, and machining quality is improved. The proximity switch is arranged to automatically control the bending angle so that excessive bending can be prevented. The rolling shaft is used for performing friction and extrusion on the inwards-concave face of the machined workpiece, and cracks and burrs on the concave face are effectively reduced.

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. When working, the bending torque is set by the experience of the workers. It cannot be adjusted in real time according to the thickness of the sheet. The processing quality of the sheet is not high. When the bending torque is not suitable, there are cracks in the sheet after bending. Defects; lack of angle control device, prone to excessive bending, and potential safety hazards; after bending, the concave plate material needs further processing due to cracks and burrs due to extrusion, resulting in a long processing cycle
