Online automatic real-time centering method and device for cold drawing forming

Abstract

The invention provides an online automatic real-time centering method used for detecting precision of a wire drawing module for wire rod drawing. The wire drawing module includes a supply machine, a cold drawing machine and a cold drawing mold arranged between the supply machine and the cold drawing machine. The method includes a preparing step. A sensing unit is arranged on the cold drawing mold. The sensing unit is connected with a control unit electrically. The method also includes an adjusting step. The cold drawing machine draws a wire rod to penetrate through a through hole of the cold drawing mold for making the wire diameter of the wire rod reduced after penetrating through the hole. When the sensing unit detects that shift of the cold drawing mold occurs, the cold drawing machine can be moved through the control unit, so that a center point of the through hole of the cold drawing mold can be overlapped with a projection point of a center point of the cold drawing machine on the same plane. The invention also provides the online automatic real-time centering device for cold drawing forming.

Description

technical field [0001] The present invention relates to a centering method and device, in particular to an online automatic real-time centering method and device for cold drawing forming. Background technique [0002] In order to process a metal wire with a thicker diameter into a metal wire with a thinner diameter, the metal wire is generally drawn and drawn by a cold pumping machine to reduce the wire diameter of the metal wire. [0003] refer to figure 1 , is the prior art disclosed in the No. M408421 patent case of China Taiwan Announcement. When it is desired to draw the metal wire rod, a mold is installed between the feeder (not shown) and the cold pump (not shown). 11. There is a tapered slot 111 inside the mold 11, and the wire 12 to be processed is inserted into the large-diameter end of the slot 111 and passed out from the small-diameter end of the slot 111 to carry out the pulling operation, and The slot 111 is used to constrict the extruded wire 12 so as to red...

AI Technical Summary

Problems solved by technology

Therefore, if the equipment is affected by external forces or deviates under long-term use, it is only after the metal wire has been drawn and the finished product is inspected that the equipment will be found to be deflected, resulting in inconsistent specifications or defects in the finished product.
