Stamping die with automatic material lifting function

Abstract

The invention discloses a stamping die with an automatic material lifting function. The stamping die comprises an upper die body, a lower die body and a guiding column. A mounting hole is formed in the lower die body and internally provided with a guiding column for lifting guiding of the upper die body, and a guiding sleeve matched with the guiding column is arranged on the upper die body. The upper die body is matched with the guiding column through the guiding sleeve, a machining area for stamping forming is arranged on the lower die body and penetrates in the width direction of the lower die body, and a protruding positioning block is arranged in the center of the machining area. A circular-arc-shaped positioning groove is formed in the positioning block, and grooves for positioning the upper die body are further formed in the end faces of the two sides in the length direction of the machining area. An arc-shaped hook plate for material lifting is further arranged on the upper diebody and fixed to the end face of one side of the upper die body, and the lower end of the arc-shaped hook plate is a hooking-up end. The hooking-up end is lower than the bottom face of the upper diebody, an arc-shaped area with the function of recovering deformation towards the die is arranged on the arc-shaped hook plate, and the hooking-up end is a circular arc upwards bending towards the die.A straight groove matched with the arc-shaped hook plate is formed in the side face of the lower die body and leads to the bottom face in the machining area.

Description

technical field [0001] The invention relates to the field of mold structure, in particular to a stamping mold capable of automatic material lifting. Background technique [0002] At present, in the process of cold stamping blanking on the stamping die, since the general blanking is blanking without waste around, the material is usually returned by the action of the unloading plate on the lower die, so that the edge of the material can lift the blank Remove from the lower mold, and then manually shake the steel plate to collect the blanks. This purely manual picking method is time-consuming, labor-intensive, and the production cycle is slow. In addition, if the production method of cutting off the edge of the material as waste is punched, it will bring a lot of inconvenience to take the material. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a punching die capable of automatic lifting, which solves the problem...
