Position detecting system for edge of winding-up H-shaped wheel of wire drawing machine and control method thereof

Abstract

The invention discloses a position detecting system for the edge of a winding-up H-shaped wheel of a wire drawing machine and a control method thereof. The method comprises the following steps that: (1) two extreme positions are calibrated; in the process that a controller adopts a motor to drive a bracket to move on a lead screw, the controller acquires distances from displacement sensors to theinner edge of the H-shaped wheel by the two displacement sensors and calibrates the two extreme positions according to the distances; angle values of encoders corresponding to the two extreme positions are acquired; and (2) the bracket is controlled to do reciprocating movement between the two extreme positions, and the controller drives the bracket to move along the lead screw by the motor, and controls the motor to rotate reversely when the bracket reaches the extreme positions, so that the purpose that the bracket moves between the two extreme positions in a reciprocating manner till the wire arranging procedure on the H-shaped wheel is finished. The position detecting system has the characteristics of high detection accuracy and easiness in implementation and the like and can effectively avoid the phenomenon of wire stacking at the edge of the H-shaped wheel.

Description

technical field [0001] The invention relates to a wire drawing machine take-up I-wheel edge position detection system and a control method thereof, which are suitable for use in wire drawing machines, enamelling machines, and various bare wire rewinding machines. Background technique [0002] Wire drawing machine is a mechanical equipment widely used in machinery manufacturing, hardware processing, wire and cable and other industries in industrial applications. Finished steel wire take-up device is the key part. Due to the inaccurate positioning of the edge position of the I-shaped wheel when the wire is taken up, "stacked wires" appear on both sides of the I-shaped wheel, and even the deformation of the bulging wheel occurs, which seriously affects the quality of the wire and the flatness of the cable arrangement. [0003] At present, the problem of taking up the I-shaped wheel is mainly to use the proximity switch or the limit switch to change the direction of the cable f...

Problems solved by technology

Its disadvantages are: 1) The movement of the mechanical sensor is realized by the rotation of the manual control handle, which has low efficiency and low precision; 2) The sensor is of mechanical contact type, and long-term use will reduce the positioning accuracy due to wear; 3) The structure is complex and affects the processing accuracy. demanding

[0004] The main disadvantages of the existing equipment and methods are: the calibration of the edge position of the I-shaped wheel is generally done manually, and the accuracy is low; "Phenomenon
