Problems solved by technology

[0002] At present, in the mechanical processing industry, molds are generally used to process mechanical parts. Nowadays, drawing dies are more and more used in processing mechanical parts. Because the original drawing dies are not designed with pressure Edge rings and drawbeads, so it is easy to wrinkle the parts during the stretching process, and has the disadvantage of low qualified rate of stretched parts

Abstract

The invention discloses a drawing die. The drawing die comprises a blank holder fixing seat (1), a blank holder (2), a draw bead (3), an insert (4), a male die fixing seat (5), a male die (6), ejector rods (8), a forming cushion block (9), a female die (10) and a female die seat (11). The lower end of the blank holder fixing seat (1) is connected with the blank holder (2). The side of the blank holder (2) is connected with the draw bead (3). The insert (4) is arranged at the right end of the blank holder fixing seat (1). The side of the insert (4) is connected with the male die fixing seat (5). The lower end of the male die fixing seat (5) is connected with the male die (6). The forming cushion block (9) is arranged at the lower end of the male die (6). The lower end of the forming cushion block (9) is connected with the ejector rods (8). The female die (10) is arranged at the right end of the forming cushion block (9) and connected with the female die seat (11). The design of the blank holder and the draw bead is adopted in the drawing die, materials cannot be wrinkled or moved in the drawing process, and parts with better quality can be obtained fast and efficiently in a drawn mode.

Description

technical field [0001] The invention relates to a mold, in particular to a stretching mold. Background technique [0002] At present, in the mechanical processing industry, molds are generally used to process mechanical parts. Nowadays, drawing dies are more and more used in processing mechanical parts. Because the original drawing dies are not designed with pressure Edge rings and drawbeads, so it is easy to wrinkle the parts during the stretching process, which has the disadvantage of low qualified rate of stretched parts. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a design that adopts blank holder ring and drawbead, so that the material does not wrinkle or move during the stretching process, and can quickly and efficiently stretch out parts with better quality. Stretch die. [0004] In order to solve the above-mentioned technical problems, the present invention provides a drawing die, which includes a ...
