Multi-pass metal drawing device based on water lubrication drawing

Abstract

The invention discloses a multi-pass metal drawing device based on water lubrication drawing. The multi-pass metal drawing device comprises a support, a drawing cavity which is fixed in the support, a sealing ring, a mold group and a lubrication chamber group which are arranged in the drawing cavity, and a cover plate which is fixed on the support, wherein the mold group is an ultra-smooth nano diamond composite coating mold; a drawing cavity lubricant inlet is aligned with the center line of a support lubricant inlet; the sealing ring, the lubrication chamber group and the mold group are sequentially placed in the drawing cavity along the drawing direction of a pipeline material; and the opening direction of a lubrication chamber is aligned with the drawing cavity lubricant inlet and outlet. The multi-pass metal drawing device can ensure that the contact area between the pipeline material and the mold group is completely immersed in a lubricant during drawing, then the excellent water lubrication property of a diamond film is brought into play, and a drawing area is effectively lubricated and cooled, so that the service life of the mold is prolonged, and the processing surface quality and the surface smooth finish and cleanliness are improved; and meanwhile, the characteristics of safety and non-pollution of a water base lubricant also ensure that a processing environment is greatly improved.

Description

technical field [0001] The invention relates to a lubricating drawing device in the technical field of processing non-ferrous metals, stainless steel and other rods, pipes and wires, in particular to a multi-pass metal drawing device based on water lubricating drawing. Background technique [0002] In the field of modern manufacturing, metal cold drawing is the most commonly used processing technology. Drawing dies have become the most commonly used key components in industries such as metal products, wires and cables, etc., with a wide range of applications and a large market capacity. In the process of metal drawing, oil-based lubricants are widely used to reduce the friction coefficient between the die and the pipe and wire, and reduce the wear of the drawing die, so as to prolong the service life of the die, improve the processing quality and production efficiency, etc. . [0003] Chemical vapor deposition (Chemical Vapor Deposition, CVD) diamond film has excellent tri...

AI Technical Summary

Problems solved by technology

However, the viscosity of the water-based lubricant is low and cannot adhere to the pipe well. If the traditional drawing device is used, the water-based lubricant will not be able to enter the drawing work area and the lubrication effect will not be achieved. The traditional drawing device The supporting device of the drawing die cannot meet the requirements of water-based lubricant drawing processing
