Production method and product of oblong flat-wire stainless steel profiled bar

Abstract

The invention discloses a production method and a product of an oblong flat-wire stainless steel profiled bar. The production method comprises the following steps of 1), first-time coarse drawing; 2), second-time coarse drawing; 3), immersion lubrication; 4), the preparation of an oblong flat-wire hole die; and 5), fine drawing: making one end of a bus of which the immersion lubrication procedure is completed penetrate into a concave die, starting a wire drawing machine to carry out a fine-drawing forming procedure, so as to make and obtain the oblong stainless steel profiled bar. The production method provided by the invention is succinct in procedures and high in efficiency; the surface defect of the bus is hereby removed first through the first-time coarse drawing; afterwards, the surface stress of the bus is hereby relieved again through the second-time coarse drawing; the surface texture of the bus is guaranteed to be stable without rupturing during the fine drawing; subsequently, the bus is immersed in a lubricant, so that a protective layer is formed on the surface of the bus and the bus plays a lubrication role between the bus and the die during the fine drawing; the friction is prevented from causing a scratch; finally, through the fine drawing, the oblong stainless steel profiled bar is made and obtained; the quality of the product is effectively guaranteed; and the improvement of the competitive power of an enterprise is facilitated.

Description

technical field [0001] The invention relates to a production method of stainless steel profiled material, in particular to a production method of rectangular flat wire stainless steel profiled material. Background technique [0002] The wire drawing die is a tool for drawing metal wires. Its body is mainly composed of a steel sleeve and a mold core. The steel sleeve is usually made of stainless steel, and the mold core can be made of hard alloy, alloy steel, natural diamond or artificial diamond. During the implementation of the drawing process, the external force forces the metal material to pass through the core of the wire drawing die, and the cross-sectional area of ​​the metal material is compressed to obtain the required cross-sectional shape and size. [0003] With the diversification of products, the demand for rectangular stainless steel profiles is increasing; however, in the production process, when the metal material is forcibly passed through the core of the wir...

Problems solved by technology

[0003] With the diversification of products, the demand for rectangular stainless steel profiles is increasing; however, in the production process, when the metal material is forcibly passed through the core of the wire drawing die, there will be greater friction, heat and extrusion stress. It is easy to be scratched or broken, and it is difficult to guarantee product quality
