Abstract

The invention provides an air rectification cap deep drawing die with deep drawing beads and relates to an air rectification cap deep drawing die. The air rectification cap deep drawing die is used for solving the problems that three sets of dies are used, drawing forming cannot be achieved, a spherical part of a deep drawn part is either ripped or wrinkled, and after a wrinkled part passes through the shaping process, the wrinkled part is not smooth, and wrinkles and folded marks still exist on the surface of the winkled part. Guide pillars are fixed to a lower die seat, and a male die is connected with the lower die seat; an edge pressing ring is arranged on the outer edge of the male die in a sleeving mode; lower die hanging rings are connected with the lower die seat; edge pressing ejecting rods in sliding fit penetrate into ejecting rod penetrating holes of the lower die seat; the edge pressing ejecting rods eject to the lower surface of the edge pressing ring; a female die is connected with an upper die seat; guide sleeves are fixed in guide sleeve fixing holes in the upper die seat; a part ejecting rod penetrates through the upper die seat and is connected with a part ejecting device; the part ejecting device is arranged in a female die counter bore; four upper die hanging rings are connected with the upper die seat, an annular boss is arranged on the lower end face of the female die, and an annular groove is formed in the upper end face of the edge pressing ring. According to the air rectification cap deep drawing die, a press is used for drawing and machining air rectification caps.

Description

technical field [0001] The invention relates to an air fairing cap drawing die, which belongs to the field of mechanical processing and stamping. Background technique [0002] Stamping is a process method of mechanical processing. It uses a press to pressurize a metal blank through a mold to cause plastic deformation to obtain parts of a certain shape, size and performance. It is one of the important processing methods in mechanical manufacturing. . There are many types of parts produced by stamping methods, and their forming methods are also varied. According to the types of forming processes, they can be divided into two categories, one is the separation process, and the other is the forming process. The forming process refers to the plastic deformation of the material without destroying the material, so as to obtain the required shape and size of the workpiece. The forming process includes bending, deep drawing, bulging, flanging, reaming, shrinking, curling, leveling, ...
