Abstract

The invention relates to the technical field of metal wire production, in particular to a wire-separated wire drawing combination die, which includes a die body and a die cover. The die cover includes a lubricating powder cavity and a front core cavity without taper. The core cavity and the lubricating powder cavity pass through the center of the mold cover; the mold body includes a tapered rear core cavity and a non-tapered matching cavity, and the rear core cavity and the matching cavity pass through the center of the mold body; the front mold A cylindrical pressure mold core and a tapered finished mold core are installed in the core cavity and the rear core cavity respectively; the inlet end of the pressure mold core is provided with a groove with powder, and the wire separation type wire drawing combination of the present invention The mold adopts the double-core separation design, which has good sealing performance, stable working environment of the mold, and a good lubricating environment. The quality of the finished wire rod is significantly improved. In addition, there are heat dissipation grooves on the periphery of the rear core cavity on the mold body to avoid mold bursting.

Description

technical field [0001] The invention relates to the technical field of metal wire production, in particular to a wire separation type wire drawing combination die. Background technique [0002] In the field of steel wire processing, one kind of steel wire drawing is carried out in dry powder wire drawing equipment. The so-called dry powder wire drawing equipment is a kind of wire drawing equipment. It uses dry lubricating powder as the wire drawing lubricant material, and the current dry powder wire drawing equipment The drawing dies are all single-mode, and do not have any powder-carrying mechanism. The powder-carrying effect is very bad, resulting in poor adhesion of the lubricating powder, and insufficient lubrication of the product during drawing, resulting in low quality of the finished product after drawing, which directly affects The overall quality of the product; in addition, when the mold works under the premise of insufficient lubrication conditions, the temperatu...
