Abstract

The invention relates to a car covering part side drawing die which is composed of an upper die part and a lower die part. The upper die part is composed of an upper tapered wedge, a drive block, a piercing punch, a material-pressing core and nitrogen springs, the lower die part is composed of a lower die seat, a lower tapered wedge, a piercing female die, nitrogen springs, a side drawing punch, buffering polyurethane, a back spring structure, a side drawing female die and a position-replacing block. The car covering part side drawing die has the advantages of saving cost of the drawing die, improving economic performance, saving time of installment and debugging of the drawing die, greatly improving production efficiency of the car covering parts and economic performance, breaking the mode that a car covering part drawing die can only achieve positive drawing and therefore being novel in operation modes and ensures position accuracy of piercing and the lateral side because of achieving positive punching and lateral drawing of the car covering parts at the same time.

Description

technical field [0001] The invention relates to an automobile mold, in particular to a side stretching mold of an automobile cover part. Background technique [0002] Stretching dies are one of the most widely used dies in stamping production. Generally, stretching dies are used for positive stretching without lateral stretching. However, with people's demand for diversified car shapes, the requirements for the shape of car panels are getting higher and higher. And direction also puts more demands on it. In order to meet the special shape requirements of some automotive panels, some automotive panels not only require punching in the front, but also require stretching on the side. Contents of the invention [0003] The object of the present invention is to provide a side stretching die for automobile panels, which is specially used for automobile panels requiring forward punching and lateral stretching. It can realize positive punching and side stretching of automobile p...
