Drawing die with function of pressing materials in a moving mode

Abstract

The invention discloses a drawing die with the function of pressing materials in a moving mode. The drawing die comprises an upper die, a blank holder, a lower die seat, a convex die and a mandril mechanism. The blank holder and the convex die are both arranged between the upper die and the lower die seat, the mandril mechanism and the blank holder correspond. The blank holder comprises a main blank holder and a movable blank holder, the movable blank holder is movably arranged on the main blank holder, a movable concave die corresponding to the top of the movable blank holder is arranged below the upper die, and a lateral driving mechanism which drives the movable blank holder to move laterally is arranged between the movable blank holder and the convex die. The lateral driving mechanism drives the movable blank holder and the movable concave die to slide laterally, so that an outward lateral drawing effect to a plate before drawing work is conducted, and moving and pressing the materials are achieved. On the basis that the drawing depth is not added, blanks are drawn completely, the using ratio of the materials is improved, sliding lines are reduced, and the drawing die is suitable for drawing process of flat plates with caps.

Description

technical field [0001] The invention relates to the technical field of drawing dies, in particular to a drawing die with the function of moving pressing materials. Background technique [0002] With the continuous development of the manufacturing industry, the pursuit of product quality and the saving of manufacturing costs have become two major concerns of enterprises. At present, under the pursuit of lightweight requirements, the thickness of automobile panels is getting thinner and thinner, which causes a series of problems such as insufficient rigidity and collapse of panels, which affects the quality of the whole vehicle. In particular, shallow-drawn panels such as hair covers, top covers, and door panels are the most important stamping parts among various types of automobile outer coverings, and their quality directly affects the appearance and safety performance of the automobile. [0003] In order to improve the rigidity of the plate, the traditional method is to in...

AI Technical Summary

Problems solved by technology

In order to fully draw the blank and improve the rigidity of the part, the drawing depth can only be increased, which is prone to slip lines and affects the quality of the part

[0005] This method can solve the above-mentioned problems to a certain extent, but it is difficult to solve the rigidity problem of relatively flat hair cover boards by using this process; at the same time, it will reduce the utilization rate of materials, increase the cost of developing automobiles, and make the production of enterprises Reduced competitiveness
