Wire compensation control method of water tank wire drawing machine

Abstract

The invention discloses a flat cable compensation control method for a water tank wire drawing machine. The flat cable compensation control method for the water tank wire drawing machine comprises the following steps: (1) determining fixing positions of a left approach switch and a right approach switch; (2) carrying out online acquisition of feedback values for reflecting displacement of a supporting point on a swinging rod of a tension arm; (3) respectively recording feedback values D1 and D2 for reflecting the displacement of the supporting point on the swinging rod of the tension arm after a flat cable moves to the position of the approach position and a position for receiving a reversing command to operate for a time T when the flat cable wheel moves to the edge of the inner side of an I-shaped wheel on one side of the approach switch by passing through the position of any approach switch; and (4) determining the next reversing delay time according to the D1 value and the D2 value. The flat cable compensation control method for the water tank wire drawing machine is capable of judging accumulation of wire or short of wire at arc R angle of the inner side of the I-shaped wheel by carrying out online acquisition of the feedback values for reflecting the displacement of the supporting point on the swinging rod of the tension arm, carrying out online regulation of reversing time points of the flat cables so as to change the reversing time of a motor and carrying out real-time compensation of flat cables on two sides of the I-shaped wheel so as to form closed-loop control, and thus the smoothness of the flat cables on the inner side of the I-shaped wheel is ensured and the quality of the flat cables is improved.

Description

technical field [0001] The invention relates to a production process of a water tank wire drawing machine, in particular to a wire arrangement compensation control method for a water tank wire drawing machine. Background technique [0002] Water tank wire drawing machine is the most common wire drawing machine in my country at present. It is widely used in the production and preprocessing of metal products such as steel wire, rope wire, prestressed steel wire, and standard parts. The quality of the wire arrangement is a very important indicator of the water tank wire drawing machine. , its main function is to reciprocate and orderly arrange metal wires of different specifications on the take-up I-shaped wheel. The quality of the wire arrangement directly affects the shift output, product quality and production cost of the later joint-stock production. Most of the water tank wire drawing machines on the market currently use variable frequency reduction motors to drive the belt...

AI Technical Summary

Problems solved by technology

Most of the water tank wire drawing machines on the market currently use variable frequency reduction motors to drive the belt drive. During the use of the I-shaped wheel, due to the tension and extrusion of the steel wire, the two sides of the I-shaped wheel will expand and there will be irregular deformation.

In order to enhance the mechanical strength of the I-shaped wheel and reduce the amount of deformation, it is necessary to leave an arc R angle on both sides of the I-shaped wheel during processing. It is easy to break the wire during use

In order to avoid the above problems, it is generally solved by manually adjusting the left and right proximity switches and adjusting the reversing position, but it is troublesome to adjust too many times, so it is necessary to design a cable compensation control method using closed-loop control
