Bending device with feedback rotating speed control and positioning detection functions

Abstract

The invention relates to a bending device with feedback rotating speed control and positioning detection functions. The bending device comprises a drive motor, a clamping fixed seat and a host arranged on a frame; a bending shaft is installed on the drive motor, and a machined piece is arranged on the clamping fixed seat; the bending device further comprises a capacitive sensing thickness detector, a pressure sensor, a proximity switch, a detection feedback device and a controller, wherein the pressure sensor and the proximity switch are arranged at the bent position of the machined piece; the detection feedback device comprises an ultrasonic crack detector arranged on the clamping fixed seat; the capacitive sensing thickness detector, the pressure sensor, the proximity switch and the ultrasonic crack detector are connected with the host respectively via a DSP (Digital Signal Processor) data processing module. The pressure sensor controls the clamping force and installation position of the machined piece, and crack detection and stage-by-stage bending are performed, so that the proportion of cracks is greatly reduced and the machining quality is improved; by controlling the bending angle, excessive bending is prevented, and the service safety of equipment is improved.

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 workpiece to be processed is clamped by manual adjustment, and the clamping force is often too large or too small, resulting in being caught during bending. The workpiece is loose or the deformation of the clamp is too large; the bending speed is set by the experience of the workers during work, which cannot be adjusted in real time with the thickness of the plate, and a constant bending force cannot be changed with the change of the bending angle. The processing quality of the plate is not high, and there are crack defects in the bent plate; the quality of the bent plate can only be detected by naked eyes, which is inaccurate and the effect is not good; lack of positioning and bending angle control devices, prone to bending deviation, Empty folding and excessive bending pose potential safety hazards
