Metal plate bending device with torque regulation and roll bending

Abstract

The invention relates to a metal plate bending device with torque regulation and roll bending. The metal plate bending device comprises a drive motor, a clamping fixed seat and a main engine which are installed on a rack, a motor shaft of the drive motor is provided with a bending shaft, and a machined workpiece is arranged on the clamping fixed seat; the metal plate bending system further comprises an ultrasonic thickness detector, a support rod, a roller and a controller, wherein the ultrasonic thickness detector is installed on the rack with the help of a support, the support rod is installed in a clamping groove of the clamping fixed seat, the roller is installed on the clamping fixed seat and is located on the concave surface side of the machined workpiece, and the controller is connected with the main engine, the upper end of the support rod is connected with a proximity switch, the roller is connected to the upper end face of an adjustment plate in a rotating mode, and the lower end face of the adjustment plate is installed in an installing groove of the clamping fixed seat with the help of a rotary shaft and a spring. Bending is conducted by using the most suitable torque, and the machining quality is improved; by means of the proximity switch, the bending angles are automatically controlled, and excessive bending is prevented; by means of the roller, friction and extrusion are carried out on the face, recessed inwards, of the machined workpiece, and cracks and burrs on the concave surface 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
