Part carrying prevention device for drawing die

Abstract

The invention provides a part carrying prevention device for a drawing die. The part carrying prevention device is arranged on a drawing female die and comprises air pipes and an air source for providing air into the air pipes, multiple through holes are formed in the drawing female die, one end of each air pipe is connected in the corresponding through hole in a sleeving mode, and the interior of each air pipe communicates with a gap between the drawing female die and a workpiece. The other end of each air pipe is connected with the air source. By arranging the part carrying prevention device is arranged, air is blown to the position between the drawing female die and the workpiece to form an air layer, the workpiece and the drawing female die are rapidly separated, it is guaranteed that the workpiece stays on a drawing male die, normal production of a die is guaranteed, and the production frequency is increased.

Description

technical field [0001] The invention belongs to the field of moulds, in particular to an anti-band device for a drawing mould. Background technique [0002] With the improvement of people's living standards, the increase in demand for cars has led to a substantial increase in car sales, which also requires car manufacturers to increase car production and increase production frequency. For the drawing dies of large-scale outer panel coverings such as automobile hood outer panels, door outer panels, and side door outer panels, which have a large plane area and a large drawing depth, after the drawing work is completed, the drawing die is lifted In the process, the drawing die will move upward together with the workpiece away from the drawing punch. Since the workpiece cannot stay on the punch, the normal production of the workpiece is affected and the production frequency is reduced. Contents of the invention [0003] In view of this, the present invention aims to propose a...
