Abstract

The invention provides a device for conveniently detecting and controlling tension of a metal wire in the wire drawing process, which is used for solving the problem of higher failure rate due to a severe working environment in the conventional tension detection and control device. The technical scheme is that: the front end of the wire drawing machine is provided with a wire unreeling wheel (1), and the tail end of the wire drawing machine is provided with a wire reeling wheel (2) using a variable frequency motor; variable frequency motors (3) are used by wire drawing units and wire reeling units; each wire drawing unit comprises a revolving drum (4), a frequency converter (5), a mechanical braking device and the like; an analog signal of a set speed is connected to a programmable logic controller (PLC) control unit and is output to the input end of the frequency converter (5) by the PLC control unit; meanwhile, an ultrasonic sensor (6) is arranged between every two wire drawing units; and the ultrasonic sensors (6) are used for transmitting corresponding data signals to serve as feedback signals for control according to variation in distances from transmitting ends and receiving ends of the ultrasonic sensors (6) to an object to be measured so as to adjust the rotation speeds of the variable frequency motors (3).

Description

technical field [0001] The invention relates to the field of metal wire production, in particular to a wire drawing tension detection and control device. Background technique [0002] In metal processing, the straight wire drawing machine is a common one. In the past, it was usually realized by a DC generator-motor unit. The tension of the metal wire is controlled by the transmission speed of the adjacent wire drawing unit. The transmission speed of the wire drawing unit If the speed does not match, there will often be no tension or excessive tension in the wire, which will cause the accumulation of metal wire or the breakage of the metal wire, which will affect the production, or the roundness of the metal wire will be damaged, and the quality of the wire is difficult to guarantee. Tension is controlled. [0003] Now with the advancement of technology and the popularization of frequency converters, frequency conversion control has begun to be widely used in straight wire d...
