Stamping punching device

Abstract

The invention discloses a stamping hole flanging device, and relates to the technical field of stamping die manufacturing. The stamping hole flanging device comprises a plurality of hole flanging female dies and a plurality of hole flanging male dies, wherein the hole flanging female dies are arranged on an upper die, and the hole flanging male dies corresponding to the hole flanging female dies respectively are arranged on a lower die. A plurality of seesaws are arranged on the lower die, and each seesaw is hinged to the lower die through a center shaft. One end of each seesaw is provided with a driving rod which is provided with a pushing rod and a guiding rod connected with the pushing rod, and the other end of each seesaw is provided with a pressing rod. When the upper die and the lower die are in a die assembling state, the hole flanging male dies are connected with the hole flanging female dies in an abutting mode. The guiding rods penetrate through the hole flanging male dies and the hole flanging female dies. The lower die is provided with guiding sleeves which are used for supporting the driving rods and lifting the pressing rods respectively. Compared with the prior art, the stamping hole flanging device has the advantages that the edge-folding and stretching processes on one face of a sheet metal part and the hole flanging process on the other face of the sheet metal part can be carried out at the same time through one-time die assembling, and working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of stamping die manufacturing, in particular to a punching hole turning device for automobile sheet metal parts. Background technique [0002] At present, the traditional mode of turning holes in the machinery industry is basically to directly transmit the downward pressure generated by the press to the parts to be turned through the machine, and use the mold to act on the sheet metal parts to realize the parts turning holes. The hole is generally turned downward from the upper surface of the part; if the hole is turned upward from the surface of the part, the sheet metal part must be placed on a floating mold, and the hole turning punch is fixed on the lower mold base, under the downward pressure of the press , the sheet metal part moves downward together with the floating part of the mold, and the hole-turning punch moves relatively upwards and acts on the sheet metal part to finally realize the hole-turni...

[0002] At present, the traditional mode of turning holes in the machinery industry is basically to directly transmit the downward pressure generated by the press to the parts to be turned through the machine, and use the mold to act on the sheet metal parts to realize the parts turning holes. The hole is generally turned downward from the upper surface of the part; if the hole is turned upward from the surface of the part, the sheet metal part must be placed on a floating mold, and the hole turning punch is fixed on the lower mold base, under the downward pressure of the press , the sheet metal part moves downward together with the floating part of the mold, and the hole-turning punch moves relatively upwards and acts on the sheet metal part to finally realize the hole-turning operation; and if the upper surface of the sheet metal part needs to be drawn, folded, and other multi-process operations At the same time, the lower surface of the sheet metal part needs to be turned upwards. The traditional stamping process cannot be realized through one-time mold loading, but requires secondary mold loading. At the same time, the mold should be designed into two sets. In this way, Not only the mold cost is increased, but the production efficiency is also greatly reduced
