Problems solved by technology

This existing drawing device has the following disadvantages: 1. The adhesion between the lubricating material and the wire blank surface is small, and the friction force between the drawing die and the wire blank is large. Find a balance between the drawing force and the drawing force - a suitable drawing angle of the drawing die; 2. The drawing die and the wire blank are not cooled well during the drawing process, a

Abstract

The invention discloses a double metal wire production device, particularly a pressure die drawing device used for producing double metal wires. The device comprises a die holder (9) and a drawing die (10) connected with the die holder (9). The device is characterized in that the wire feeding side of the drawing die (10) is provided with an oil pressure cavity (2) communicated with a hydraulic power device, and the wire feeding position of the oil pressure cavity (2) is provided with a sealing device. The device has the advantages that the lubricating material has large adhesive force on the wire blank surface; the drawing die has small friction with the wire surface; the drawing die and wire blank can be cooled and has balanced temperature at any time during drawing; and the device can achieve good metallurgical bonding, good wire surface quality with surface stress evenly distributed and more superfine radial dimension.

Description

technical field [0001] The invention relates to a bimetal wire production device, in particular to a pressure drawing die device for producing bimetal wire. Background technique [0002] At present, the production method of bimetallic composite wire blanks such as copper-clad aluminum or copper-clad steel is mainly the cladding welding method. The longitudinal joints formed after cladding are made into bimetallic composite wire blanks such as copper-clad aluminum or copper-clad steel; In one body, we can produce copper-clad aluminum or copper-clad steel and other bimetallic composite wires of various specifications required by users. [0003] The drawing die devices used in the drawing process of bimetallic wire blanks are all open, that is, a drawing die is installed on the die base, and one side of the drawing die is the wire inlet end, and the other side is the wire outlet end , the center hole of the drawing die on the side of the wire inlet is conical, and the center ...
