SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an efficient car hardware both sides right angle forming device that once bends of portion to raise the efficiency, and reduce the mould cost.
The utility model relates to a one-time bending forming device for right-angled bent parts at two sides of automobile hardware, which comprises an upper die base capable of moving up and down and a fixed lower die base; the lower surface of the upper die base is connected with a concave upper die forming punch, and a stripping block which can elastically lift relative to the groove is arranged in the groove of the upper die forming punch; the lower die forming punch is characterized in that an elastically liftable lower die forming punch is arranged on a lower die base, a pair of lower die forming inlet blocks which are symmetrical are further connected to the periphery of the lower die forming punch and the lower die base, the upper die forming punch and the stripping block are opposite to the lower die forming punch, the lower die forming punch is in a convex shape, and the upper part of the wall surface of the lower die forming inlet block facing the lower die forming punch protrudes towards the lower die forming punch.
The utility model relates to a one-time bending forming device of automobile hardware both sides right angle bending portion, place punching press material on lower mould shaping drift surface, its both ends are taken on the lower mould shaping income piece surface of corresponding side, the upper die base moves down and drives upper mould shaping drift and takes off the material piece and move down, it all contacts with punching press material to take off material piece and upper mould shaping drift, along with the continuation of upper die base moves down, take off the material piece and push down the lower mould shaping drift, and the punching press material is pushed down to the upper mould shaping drift, make punching press material both ends upwards buckle along the shape of lower mould shaping income piece, then the upper die base continues to move down, punching press material moves down along with lower mould shaping drift, until upper die base and die holder are totally closed, the punching press material continues to push down by the upper mould shaping drift, make punching press material bend down along lower mould shaping drift lateral wall, until upper die base and die holder are totally closed, realize punching, the two sides of the bending die can be formed with bending parts with an angle of 90 degrees at one time, then the upper die base moves upwards until the upper die base is separated from the lower die base, the stripping block returns to the original position under the elastic action, and the lower die forming punch also returns to the original position under the elastic action. This one-time forming device that bends of car hardware both sides right angle portion of bending can once only bend in punching press material's both sides and form the portion of bending at two 90 jiaos, and work efficiency is high, and the mould is with low costs.

Detailed Description
A one-time bending forming device for right-angle bending parts on two sides of automobile hardware is shown in figures 1 and 2 and comprises an upper die holder 1 and a fixed lower die holder 2, wherein the upper die holder 1 can move up and down; the lower surface of the upper die holder 1 is connected with a concave upper die forming punch 3, and a stripping block 4 which can elastically lift relative to the groove is arranged in the groove of the upper die forming punch 3; the upper die forming punch 3 and the stripping block 4 are opposite to the lower die forming punch 5, the lower die forming punch 5 is in a convex shape, and the upper part of the wall surface of the lower die forming punch 6 facing the lower die forming punch 5 protrudes towards the lower die forming punch.
An upper die spring 7 (preferably a nitrogen spring) is connected to the lower surface of the upper die holder 1, and after the upper die spring 7 downwards penetrates through the upper die forming punch 3, the free end of the upper die spring is connected with the stripping block 4. The upper die spring 7 can be replaced by a spring plate, and the replacement mode belongs to the conventional replacement mode in the field.
The upper surface of the lower die holder 2 is connected with a lower die spring 8 (preferably a nitrogen spring), and the free end of the lower die spring 8 is connected with a lower die forming punch 5. The lower die spring 8 can also be replaced by a spring plate, and the replacement mode belongs to the conventional replacement in the field.
The lower die springs 8 are two in number, so that the lower die forming punch 5 can descend smoothly when being pressed down.
An upper clamping plate 9 is arranged on the lower surface of the upper die holder 1, and the upper die forming punch 3 is fixed on the upper clamping plate 9.
The upper surface of the lower die forming insert 6 is provided with a positioning block 10 opposite to the upper clamping plate 9, when the upper die holder 1 moves downwards, the upper clamping plate 9 abuts against the positioning block 10, the upper die holder 1 and the lower die holder 2 are completely closed, and the upper die holder 1 does not descend any more.
