Abstract

The invention discloses a multi-station punching / assembling composite die. A punching positioning hole, a first punching assembly hole, a second punching assembly hole, a landing edge waste cut-off station, a first blanking station, an idle station and a second blanking station are provided in this order between upper and lower die holders with a progressive punching die as a base body. A furtheridle station and a press riveting assembly station are orderly added between the punching assembly hole and the landing edge waste cut-off station. A press riveting assembly terrace die is arranged on the upper die holder of the progressive punching die at the position of the press riveting assembly station, while a press riveting assembly female die module is arranged on the lower die holder. Two pressure heads are mounted on the two side faces of the upper die holder in a direction parallel to a tape feeding direction, respectively. The structure of the lower die holder of the progressive punching die is changed into a cross-shaped structure from a rectangular structure and the centre of symmetry of the cross-shaped structure is coincident with the centre of the press riveting assembly station. Besides, a gate type automatic feeding mechanism for automatically feeding pressure riveting nuts is mounted on the cross-shaped structure of the lower die holder right under the pressure heads which are disposed on the two side faces of the upper die holder of the progressive punching die. The composite die realizes the continuity and complete automation of production.

Description

technical field [0001] The invention relates to a composite mold, in particular to a multi-station stamping and assembly composite mold. Background technique [0002] At present, in the sheet metal industry, the connecting nuts used to fix the sheet metal parts generally use riveting to fix the nuts on the sheet metal parts. There are two ways to install the riveting nuts. It is mainly used for riveting sheet metal parts in small batches and single-piece repairs; the second is riveting with stamping dies, which is mainly used for riveting large-scale single-variety sheet metal parts. And the stamping forming of the sheet metal parts and the assembly of the rivet nuts are completed on two sets of molds respectively. In this way, a large amount of equipment, energy, materials and human resources will inevitably be wasted, and the production efficiency is low, the compatibility with the accuracy deviation of the nut is low, and the quality of the pressure riveting is unstable...
