Abstract

The invention discloses a swing arm type press fit mechanism. An upper support (3) is arranged on an upper material press core (1), a lower support (16) is hinged with the upper support (3), a recessed die insert (10) is arranged on the upper material press core (1), a terrace die insert (5) matched with the recessed die insert (10) is arranged on the lower support (16), and an elastic ejection mechanism used for ejecting the lower support (16) is arranged on the recessed die insert (10). The swing arm type press fit mechanism further comprises a driving mechanism used for driving the lower support (16) to swing. The driving mechanism drives the lower support (16) to swing and drives the terrace die insert (5) and and the recessed die insert (10) to close to finish press fit action. The mechanism resolves the problem of automation production of dies of metal plates with press fit structure and improves production efficiency of the dies of the metal plates with press fit structure.

Description

technical field [0001] The invention relates to the field of molds for processing automobile body sheet metal parts, in particular to a swing arm type pressing mechanism. Background technique [0002] The press-fitting of automobile body sheet metal parts means that under the action of the mold, firstly, the edge of the part is turned from a straight edge to a vertical edge, then the vertical edge is pre-bent to a 45° edge, and finally, it is crushed to a Stamping process in which the pressing surface is parallel to the surface of the part (such as image 3 shown). Therefore, in the existing mold manufacturing technology, if you want to complete the process in this state, the usual way is to use a common pressing mold for pressing. Ordinary mold pressing is to install the pressing mold on the press, run up and down through the slider of the press, drive the wedge plate to push the pre-bending punch, the vertical edge of the pre-bending outer plate is 45° and then exit, and ...
