Production method for hexagonal stainless steel profiled bar and product thereof

Abstract

The invention discloses a production method for a hexagonal stainless steel profiled bar and a product thereof. The production method comprises the following steps that (1), first roughing extracting is conducted; (2), second roughing extracting is conducted; (3), soaking and lubricating are conducted; (4), an hexagonal eye model is prepared; and (5), fine extracting is conducted, specifically, one end of a soaked and lubricated busbar is penetrated into a concave die, a wire drawing machine is started to conduct the fine extracting forming working procedure, and the hexagonal stainless steel profiled bar is prepared. The production method is concise in working procedure and high in efficiency. Firstly, through first roughing extracting, the surface defect of the busbar is removed; then, through second roughing extracting, and the surface stress of the busbar is eliminated, so that it is guaranteed that the surface structure of the busbar is stable and does not fracture; the busbar is soaked into a lubricating agent to form a protective layer on the surface of the busbar, the lubricating effect is achieved between the die and the busbar when fine extracting machining is conducted, so that scratching caused by friction is avoided; and finally, through fine extracting, the hexagonal stainless steel profiled bar is prepared, the quality of the product is effectively guaranteed, and the production method is favorable for improving enterprise competitiveness.

Description

Technical field [0001] The invention relates to a method for producing hexagonal stainless steel profiled materials, in particular to a method for producing hexagonal stainless steel profiled materials. 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 hexagonal stainless steel profiles is increasing; however, in the production process, when the metal material is forced through the core of the drawing die, greater friction, ...
