Die box component of wire drawing machine

Abstract

The invention relates to a die box component for reducing the drawing diameter of a metal wire on a water tank wire drawing machine. The die box component comprises a die holder, a die sleeve, a joint bearing, a wire drawing die, a die pin and a limit screw, wherein the die holder is fixedly arranged on a tank body of the wire drawing machine; the die sleeve is arranged in the die holder through the joint bearing, and is provided with a shaft retainer ring for limiting the axial movement of the die sleeve in the joint bearing; the head end of the die sleeve is provided with a conical wire inlet; the tail end of the die sleeve is provided with a concave cavity; the wire drawing die is arranged in the concave cavity, and is compressed and fixed through the hollow die pin; the outer wall of the tail part of the die sleeve is provided with a limit groove; the tail part of the die holder is provided with the limit screw; and the inner end of the limit screw is pressed in the limit groove, and is used for limiting the rotation of the die sleeve. The die box component has a skillful, compact and reasonable structure; and the wire drawing die is arranged through the joint bearing, and can be finely adjusted in a certain angle range according to the height of the metal wire, so that the metal wire is prevented from being damaged, the final product quality is improved, and the service life of the die box component is prolonged.

Description

technical field [0001] The invention belongs to the technical field of metal product production, and relates to an accessory part of a water tank wire drawing machine, in particular to a mold box part used for drawing and reducing the diameter of metal wires. Background technique [0002] With the development of the metal products industry, high speed, high efficiency, low cost and strong process adaptability have become the pursuit goals of production enterprises. Wire drawing machine is a kind of mechanical equipment widely used in machinery manufacturing, metal processing, petrochemical industry, wire and cable and other industries. It is used to draw wire or rod to make the diameter, roundness, The internal metallographic structure, surface finish and straightening degree all meet the raw material processing requirements for the production of standard parts and other metal products. Therefore, the pretreatment quality of the wire or bar by the wire drawing machine is di...

AI Technical Summary

Problems solved by technology

In actual operation, there is often a certain height difference between the walking height of the metal wire and the height of the center hole of the wire drawing die, and the wire drawing die in the existing mold box parts is usually fixed, which causes the wire wire to enter the wire drawing at a certain angle mold, it is easy to cause damage to the wire, and the quality of the final product will be affected due to the uneven stress of the wire

In addition, the mold box parts work under this condition for a long time, and their service life is also affected
