Brief Introduction
Stainless steel wire drawing die
Drawing die is one of the important tools for stainless steel wire drawing production in metal products industry. The quality level of wire drawing die directly affects the quality of stainless steel wire, output, mold loss and economic benefits of product production. At present, the wire drawing die which is commonly used in China is made of hard alloy, and the service life of the wire drawing die is short. Therefore, research on the geometry of the wire drawing die and the die hole is to extend the service life of the wire drawing die, and realize high speed and continuous. One of the important ways to automate production. High-quality special steel stainless steel wire is the main product, and in the production process, the drawing die has a short service life and frequent mold change, thus affecting the output of the stainless steel wire. Since the drawing die of drawing special steel stainless steel wire is a hole type of ordinary carbon and spring stainless steel wire, it is an urgent task to reform the current mold and improve the service life of the wire drawing die. 2) The working cone is the main area where the stainless steel wire passes and undergoes plastic deformation, and it is subjected to large deformation force and friction force, and it is affected by the taper angle of the working surface. Therefore, under certain drawing conditions. There must be an angular range that minimizes the pull-out force when the stainless steel wire is plastically deformed in this angular range, and the frictional force of the wire drawing die is minimized. Therefore, the working cone (2a) of the drawing die plays a leading role in the service life of the wire drawing die. In order to find a suitable angle for drawing the working cone of special steel stainless steel wire drawing die, we have drawn the pull force test for several different angle drawing die. Due to the limitations of the test method and core material. The precision of the drawing part of the wire drawing die is not enough, and the horizontal core material can not meet the ideal requirements. Therefore, the in-depth study of the core alloy composition and structure should be carried out, and the further testing methods and advanced molding equipment and process technology can be used. Achieve a qualitative flyby.
