Drawing processing forming mold for sheets with raised middle portions

Abstract

The invention discloses a drawing processing forming mold, capable of quick and accurate raw material positioning, for sheets with raised middle portions. The drawing processing forming mold, capable of quick and accurate raw material positioning, for the sheets with the raised middle portions comprises a lower mold holder and an upper mold holder, wherein a lower forming base is arranged on the lower mold holder, a lower forming block is detachably connected with the lower forming base, side boundary grooves which coincide with side boundaries of two sides of an unprocessed raw material are formed in the portions, at two sides of the lower forming block, on the lower forming base respectively, lateral forming blocks for conducting calendaring on corresponding raised surfaces of two sides of each workpiece are arranged at the portions, at the two sides of the lower forming block, on the upper mold holder respectively, a top forming block is arranged at the portion, between the two lateral forming blocks, on the upper mold holder, two positioning pins which match positioning holes in the workpieces are arranged on the lower forming block, a plurality of lower positioning and guiding blocks are arranged at the portions, at the two sides of the lower forming block, on the lower mold holder at intervals respectively, and upper positioning and guiding blocks in clearance fit with the adjacent lower positioning and guiding blocks are arranged on the upper mold holder.

Description

technical field [0001] The invention relates to a stamping forming die, in particular to a drawing processing forming die for a plate part with a convex middle. Background technique [0002] When the protruding plate in the middle is formed by drawing through the stamping die, the accuracy of placing the workpiece on the punch directly affects the quality of the subsequent forming, so the operator needs to spend more time carefully calibrating when placing the workpiece to ensure the accuracy of the workpiece accuracy. Moreover, when the shapes of the two workpieces on the left and right are close to each other, it is very easy to be confused, which requires more careful operation, has higher requirements on the operator, and reduces the processing efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a forming die for drawing processing of plate parts with a raised middle part that can quickly and accurat...
