Drawing die for automobile wheel cover supporting plate

Abstract

The invention belongs to the technical field of drawing dies, and discloses an automobile wheel cover supporting plate drawing die which comprises an upper die base and a lower die base, the upper die base is located above the lower die base, a male die is installed at the bottom of the upper die base, a female die is connected to the top of the lower die base, and a blank holder is fixed to the side edge of the top of the female die. A cavity groove is formed in the top end of the lower mold base, two limiting blocks are slidably connected into the cavity groove, and a first spring is fixed between the two limiting blocks. Through cooperation of the supporting rods, the limiting blocks, the cavity groove and the first spring, vibration impact during mold closing can be greatly reduced, then component vibration is effectively prevented, collision damage is reduced, and the service life of the component is prolonged. The stability of the device is improved, the service life of the device is prolonged, meanwhile, the female die can be supported and limited through cooperation of the positioning rods and the positioning holes, so that the female die is prevented from shaking and shifting during movement, and the positioning accuracy is greatly guaranteed.

Description

technical field [0001] The invention belongs to the technical field of drawing dies, in particular to a drawing die for an automobile wheel cover support plate. Background technique [0002] Drawing is a stamping process that uses a drawing die to turn a flat sheet into an open hollow part, and uses a punch to squeeze the sheet into the die to form a three-dimensional part with the shape of the cavity of the die, also known as drawing or drawing. Deep drawing is the most important three-dimensional forming method of sheet metal. [0003] In the Chinese patent with the patent number CN201520163856.0, a drawing die for the support plate of the automobile wheel cover is disclosed. It avoids the problem that the material is deformed in different directions, which makes it difficult to reshape the bending joint. However, there are still some defects in the use of this device. Vibration affects the stability, and the damage is large, which greatly shortens the service life of th...
