Embodiment Construction

[0015] Such as image 3 As shown, the cup-type progressive die with side holes in this specific embodiment divides the entire process flow into 22 stations from g1 to g22 when processing the ignition tube. Among them, the g1 station is the punching hole and the process incision station; the g2 station is the punching process incision station; g3 and g4 are empty stations; the g5 station is the first step drawing station; the g6 station is the Empty station; g7 station is the second drawing station; g8 station is the empty station; g9 station is the first step shaping station; g10 station is the empty station; g11 station is the second step Shaping station; g12 and g13 stations are empty stations; g14 station is the first side punching station, punching out twelve symmetrical side holes; g15 and g16 stations are empty stations; g17 station is The second side punching station, punch out six side holes; g18, g19 stations are empty stations; g20 station is the third step shaping ...

Abstract

The invention discloses a side hole progressive die comprising two sets or more than two sets of deep drawing devices and a side punching device. The side punching device is arranged behind the deep drawing device and comprises an upper die, a lower die, an elastic structure, a side punching structure and a discharge structure; the side punching structure and the discharge structure are arranged between the upper die and the lower die; and the elastic structure is positioned in the upper die and acts on between the discharge structure and the upper die. With the adoption of the technical scheme, the side hole progressive die can well finish deep drawing since two sets or more than two sets of the depth-drawing devices are arranged; the side hole progressive die can greatly improve the processing efficiency and make rapid large-batch production to ensure timely supply compared with the traditional processing mode of adopting multidie single procedure as the deep drawing die and the side punching die are combined together; and meanwhile, the labor cost is greatly reduced, and the labor of operators is lightened. In addition, the side hole progressive die avoids the precision error brought by the moving of a workpiece blank between different working positions, thereby having higher processing precision and better quality stability.

Description

technical field [0001] The invention relates to the technical field of mold design, in particular to a cup-type progressive mold with side holes. Background technique [0002] Progressive die is a relatively advanced die at this stage. Its most basic principle is to combine multiple original dies together to realize multi-process automation. It has the advantages of high efficiency and guaranteed processing quality. A major development direction of design. The ignition tube is the core and key component of the airbag control of high-end cars. Its structure is as follows: Figures 1 to 2 shown. It can be seen from the figure that the ignition tube is a cup-shaped structure, including a cup wall 12 and a cup bottom 13, and 6 groups are evenly arranged along the circumference of the cup wall 12, and each group has three groups, with a total of 18 round holes 14. The height of the cup wall is 20mm, and the diameter of the outer circle is φ20.5mm. Since the processing material...
