Embodiment Construction

[0016] Such as Figure 4 As shown, the side hole cover type progressive die of this specific embodiment divides the entire processing process flow into 25 stations from g1 to g25 when processing the inflatable cover. Among them, the g1 station is the punching guide hole and the process incision station; the g2 station is the punching process incision station; the g3 station is the empty station; the g4 station is the first step drawing station; the g5 station is the Empty station; g6 station is the second step drawing station; g7 station is the empty station; g8 station is the third step drawing station; g9 station is the empty station; g10 station is the shaping station station; station g11 is an empty station; station g12 is the first side punching station, and four symmetrical side holes are punched out on the side wall of the blank of the cover part blank drawn out; g13, g14, g15 three The first station is an empty station; the g16 station is the second side punching stat...

Abstract

The invention discloses a side hole cover progressive die comprising more than two sets of deep drawing devices which are arranged at a deep drawing working position for drawing material strips deep. The side hole cover progressive die further comprises a side punching device; the deep drawing devices draw deep in two steps or more than two steps; the side punching device is arranged on a side punching working position behind the deep drawing device for side punching of side holes on the side wall of a cover part blank drawn deep out by the material strip. With the adoption of the technical scheme, 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 die design, in particular to a side hole cover type progressive die. 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 processing of side hole cover parts requires not only deep drawing, but also side hole punching. The process is relatively complicated. At present, it is generally carried out in a single process with multiple molds, so the processing efficiency is low, and the quality cannot be guaranteed. for example Figures 1 to 3 Inflatable cover shown. The inflatable cover is the core key component of the airbag control of high-end cars. Its production material is generally SPCC cold-rolled steel plate with a thickness of 2mm. The he...
