Production method for U-shaped stainless steel profiled bar and product of production method

Abstract

The invention discloses a production method for a U-shaped stainless steel profiled bar and a product of the production method. The production method includes the following steps that firstly, the first time of rough drawing is conducted; secondly, the second time of rough drawing is conducted; thirdly, soaking and lubricating are conducted; fourthly, a U-shaped eye die is prepared; and fifthly, precise drawing is conducted, wherein one end of a busbar obtained after the soaking and lubricating process penetrates into the U-shaped die, a wire drawing machine is started for conducting the precise drawing forming process, and the U-shaped stainless steel profiled bar is prepared. The processes of the production method are simple, and efficiency is high; surface defects of the busbar are removed through the first time of rough drawing so that the surface of the busbar can be smooth preliminarily; then surface stress of the busbar is eliminated through the second time of rough drawing so that it is ensured that the surface organization of the busbar is stable and does not crack during precise drawing; then the busbar is soaked into a lubricating agent so that a protection layer can be formed on the surface of the busbar, a lubricating effect is achieved between the busbar and the die when the busbar is subjected to precise drawing machining, and scratches caused by friction are avoided; and finally, the stainless steel profiled bar is prepared through precise drawing, the quality product is effectively ensured, and the enterprise competitiveness is better improved.

Description

Technical field [0001] The invention relates to a method for producing concave stainless steel profiles, in particular to a method for producing concave stainless steel profiles. 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 core. The steel sleeve is usually made of stainless steel. The core can be made of cemented carbide, 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 wire drawing die core, and the cross-sectional area of ​​the metal material is compressed to obtain the required cross-sectional area shape and size. [0003] With the diversification of products, the demand for concave stainless steel profiles is increasing; however, in the production process, when the metal material is forced to pass through the core of the drawing die, greater friction, heat and extrusion...
