Tuning roller-free straight wiredrawing machine, electrical system and tension calculation method

Abstract

The invention discloses a tuning roller-free straight wiredrawing machine, an electrical system and a tension calculation method and relates to the field of straight wiredrawing machines. The tension calculation method comprises the following steps: running current I1 of a reel motor is preset; output torque of the reel motor is calculated according to a formula as shown in the specification; pulling force of the reel motor on a steel wire is calculated according to the formula F pulling force=TeI / R; tensile force of the steel wire is calculated according to the formula F tensile force=F module + F pulling force + -F pulling force; whether F tensile force meets requirements is judged; if F tensile force meets requirements, the method is finished; and if F tensile force doesn't meet requirements, running current I1 of the reel motor is reset, and tensile force of the steel wire is recalculated. According to the invention, tensile force of the steel wire can be controlled and adjusted, and production requirements are met. In addition, the tuning roller-free straight wiredrawing machine has a simple structure and is convenient for people to use.

Description

technical field [0001] The invention relates to the field of straight wire drawing machines, in particular to a straight wire drawing machine without tuning rollers, an electrical system and a tension calculation method. Background technique [0002] Straight-in wire drawing machine is a common metal wire processing equipment, which can process high, medium and low-carbon steel wire, stainless steel wire, copper wire, alloy copper wire, aluminum alloy wire, etc. With the development of metal products, the straight wire drawing machine is widely used in the metal product industry (such as steel cord, bead wire, hose steel wire, steel strand, steel wire rope and welding consumables, etc.). The characteristics of high finished wire speed, stable drawing, small wire deformation, low wire breakage rate and low equipment failure rate are deeply loved by users. [0003] The straight wire drawing machine includes wire pay-off equipment, several reels equipped with wire drawing dies...

AI Technical Summary

Problems solved by technology

[0006] (1) When the straight wire drawing machine is used, the tuning roller needs to adjust the tension of the steel wire in a long-term state, which not only makes the structure of the straight wire drawing machine more complicated, but also the long-term moving tuning roller is easy to damage the parts connected to the tuning roller. Cylinder, the maintenance cost after the cylinder is damaged is high, which in turn increases the cost of use

[0007] (2) In the case of harsh external environment, the working efficiency of the tension sensor of the tuning roller is low (displacement sensor and potentiometer have signal attenuation and interference problems, and the tension sensor used is expensive and easily damaged), which is not convenient for people to use
