Abstract

The invention discloses a process optimization method for a drawing die. According to the process optimization method of the drawing die provided by the embodiment of the invention, the die surface function of the curved surface drawing die beneficial to metal flowing is constructed, and the calculation expression of the drawing force is obtained based on the die surface function of the curved surface drawing. When the curved surface drawing die provided by the invention is applied to the drawing die, the maximum stress and the external drawing force are effectively reduced, so that the quality and the yield of a drawn product are favorably improved, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of manufacturing metal wire drawing dies, in particular to a process optimization method for drawing dies. Background technique [0002] At present, for the production method of wire rods, most of the drawing dies used by some wire rod manufacturers are traditional tapered drawing dies. Some scholars have made in-depth research on the existing drawing dies. For example, Liu Youqiang designed an oil hole on the tapered die surface so that the lubricating oil can enter the die for lubrication during drawing, so as to reduce the stress during drawing. Frictional resistance; Ma Shentong has a cylinder with a through hole in the middle of the mold core to reduce the wear of the mold core and shorten the life. composition. However, these studies only improved on the basis of the tapered mold, and did not make a targeted study on the shape of the mold surface. Therefore, there is no fundamental solution to the p...
