Embodiment

[0023] The utility model relates to a stamping die of a stepped cylindrical part, which comprises a stamping lower die, a stamping upper die, a material return device and a transmission device. Such as figure 1 As shown, the stamping upper die includes an upper template 1 and a punch 2 connected to the lower surface of the upper template 1 by threads, the punch 2 is cylindrical, and a spring washer is installed at the threaded connection to prevent loosening. The stamping lower die includes two punching parts that are symmetrical about the punch 2 axis. The punching part includes a vertical shaft 3. The outside of the vertical shaft 3 is connected with a shaft sleeve 4 through a one-way bearing. The shaft sleeve 4 is welded axially symmetrically with a primary pull Stretching half of the die 5 and half of the stretch shaping die 6. Stretching pin 20 is inserted on the initial drawing die 5 . And the bottoms of the primary stretching die and the stretching and shaping die 6 a...

Abstract

The invention belongs to the field of stamping dies, and specifically discloses a stepped cylindrical part stamping die. The stepped cylindrical part stamping die comprises a rack, wherein a stampinglower die, a stamping upper die, a return device and a transmission device are installed on the rack; the stamping upper die comprises an upper die plate and a male die; the stamping lower die comprises two stamping parts which are axially symmetric relative to the male die; each stamping part comprises a vertical shaft and a shaft sleeve, and a half of a first-time drawing female die and a half of a drawing and shaping female die are welded on the shaft sleeve; the return device comprises a bearing plate, a return plate and a continuous return spring, and avoidance holes of the return plate are formed in the bottoms of the first-time drawing female die and the drawing and shaping female die; and the transmission device comprises a two-way hydraulic pump, a die changing hydraulic cylinder,an upper die hydraulic cylinder and a stamping hydraulic cylinder. When the technical scheme is adopted, the technical problems of high cost and manpower waste during exchange due to dispersion of the stamping die can be solved. Therefore, the scheme can be widely used for stamping stepped cylindrical parts.

Description

technical field [0001] The invention relates to the field of stamping dies, in particular to a stamping die for stepped cylindrical parts. Background technique [0002] A stepped cylindrical part is a cylindrical part with a stepped side wall. The side wall is stepped, which is convenient for manual picking, and can play the role of anti-slip. [0003] In the prior art, the process of manufacturing stepped cylindrical parts from medium-thick plates is relatively complicated. In the stamping process, several sets of dies are generally required to stamp medium-thick plates into stepped cylindrical parts to meet the needs of users. And when one set of dies completes stamping, it is necessary to manually replace the lower parts and move the parts to the next set of stamping dies to complete the stamping. Each set of stamping dies requires complete configuration, and manual operation is required when changing dies. The manufacturing and maintenance costs of the mold are very h...
