Sectional type bending machining device based on positioning control

Abstract

The invention relates to a sectional type bending machining device based on positioning control. The sectional type bending machining device comprises a driving motor arranged on a rack, a clamping fixing base and a host; a bending shaft is installed on the driving motor, and a machined workpiece is arranged on the clamping fixing base; the sectional type bending machining device further comprises an X-ray thickness detector installed on the rack, a supporting rod installed in a clamping groove of the clamping fixing base, a first pressure sensor installed on the side face of the machined workpiece, a second pressure sensor installed on the bottom face of the machined workpiece, a third pressure sensor and a controller, wherein the third pressure sensor is arranged on the clamping fixing base through a stopping block, and the controller is connected with the host; a proximity switch is connected to the upper end of the supporting rod, and the third pressure sensor is arranged in an installation groove of the stopping block through a spring; and pressing plates are symmetrically arranged on the inner side wall of the clamping groove, each pressing plate is evenly provided with a plurality of pressure detection points, and the pressure detection points are connected with the first 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. When working, the bending torque is set by the experience of the workers. It cannot be adjusted in real time with the thickness of the plate, and the constant bending force cannot be changed with the change of the bending angle. The bending effect is not good, and there are crack defects in the bent plate; the lack of angle control device is prone to excessive bending, and there are also potential safety hazards; according to experience, the workpiece to be processed is clamped, and the clamping force is too large to cause deformation Excessive, too small clamping force leads to loose defects; the installation and positioning of the workpiece to be processed is not accurate, the bending position is easy to shift, and there will be empty bending phenomenon
