Cold drawing machine for cold working extension of high-temperature alloy wire

Abstract

The invention relates to the technical field of alloy manufacturing, and discloses a cold-drawing machine for high-temperature alloy wire cold working extension, which comprises a workbench, a die device is placed on one side of the top end of the workbench, a die orifice is transversely formed in the die device, and a winding device is placed on the other side of the top end of the workbench. The alloy wire penetrates through a die opening of the die device and is connected with a winding roller of the winding device, and the shaping device is fixedly connected to the top end of the portion, located between the die device and the winding device, of the workbench. The shaping device is arranged between the mold device and the winding device, the lower roller and the upper roller are arranged in the shaping device and above and below the alloy wire, and the alloy wire just moved out of the mold device is kept in a horizontal state through the lower roller and the upper roller; the friction force between the alloy wire which is not cooled and shaped and each part of the die orifice of the die device is effectively promoted to be the same, the surface integrity of the alloy wire is enhanced, and the quality of alloy wire finished products is improved.

Description

technical field [0001] The invention relates to the technical field of alloy manufacturing, in particular to a cold drawing machine for cold working and stretching of high temperature alloy wires. Background technique [0002] Cold drawing is a processing technology of materials, which is often used for metal materials. Specifically, in order to achieve a certain shape and certain mechanical properties, the material is drawn at room temperature. The existing cold drawing machine is composed of a die device, a winding device, etc. Through the rotational force of the winding device, the alloy wire material is passed through the die device to be thinned and elongated, so as to achieve the required wire diameter specification. . Because the finished product after cold drawing has the advantages of higher dimensional accuracy and better surface finish than hot forming, this kind of cold drawing machine is widely used. [0003] However, the existing cold drawing machine still ha...
