Abstract

The invention relates to a bending machine based on PLC plate thickness detection and rotation speed control. The bending machine comprises a drive motor arranged on a rack, a clamping fixed base and a PLC host used for controlling the drive motor, wherein a bending shaft is arranged on a motor shaft of the drive motor, and a to-be-machined member is arranged on the clamping fixed base. The bending machine further comprises an ultrasonic thickness detector arranged on the rack by virtue of a first bracket, a detection feedback device and a motor speed setting controller connected with the PLC host, wherein the detection feedback device comprises an ultrasonic crack detector mounted on the clamping fixed base by virtue of a second bracket; the ultrasonic thickness detector and the ultrasonic crack detector are respectively connected with the PLC host by virtue of a DSP data processing module. The invention further provides a bending machining method adopting the bending machine. The bending machine is used for bending the to-be-machined member at a most suitable rotating speed, thereby preventing the to-be-machined member from being overlow or overlarge rotating speed, reducing a number of cracks, and improving the bending machining quality.

Description

technical field [0001] The invention relates to the field of metal processing equipment, in particular to a bending machine and a bending processing method for sheet metal processing based on PLC plate thickness detection and speed adjustment. Background technique [0002] The currently used sheet metal bending machines are commonly used in two types: mechanical and hydraulic. Mechanical bending machines use motors to move up and down through a series of gears and eccentric wheels. 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 their popularity is limited due to their high price and complex structure. 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 bend...
