Description
Technical field
The present invention relates to method for metal working and molds, and in particular to a kind of punching press side for air bag substrate production
Method and mold.
Background technology
Air bag substrate is a significant components, played in air bag assembling process fixed, fuse export, with
The effect of diffuser connection.The continuous modular form of component generally use is developed, and each step work is passed through on strip material upper mold
After sequence, the blanking after specific shape, shaping at its surface punching press finally obtains finished product.In it produces preparation process, metal
The stock utilization of material strip is an important indicator.Also, it also needs to ensure while improving metal material belt stock utilization,
Metal material belt still maintains secured after cutting, punching press with the junction of product, prevents the generation product in punching course from falling off
The phenomenon that.
Chinese invention patent CN201410159465.1 discloses a kind of metal tin cover continuous punch forming method and device,
The first forming section is stamped and formed out to the metallic plate using the first punch die of punching unit, and makes the metallic plate displacement, and should
Punching unit drives the second punch die to continue the first forming section punching press to formation, and makes first forming section be deformed into one to have
Second forming section of different cross section shape, while punching press is carried out to the metallic plate using first punch die, it can be in second forming
Portion side forms first forming section, and persistent loop aforesaid operations step can provide not the same position continuous punching
With the metal object of cross sectional shape, but the utilization rate of metal material belt is not studied.
For another example Chinese utility model patent CN201720782407.3 discloses a kind of for secure ram air bag component
Mold utilizes multiple corresponding forming convax moulds gradually secure ram of the multiple molding concave dies and lower template setting of stripper plate setting
Air bag component, improves the shape of air-bag module step by step, and when processing, multistep carries out punching press to air-bag module simultaneously
Molding, improves machining accuracy, a mold completes the processing of all air-bag modules, substantially increases the effect of production
Rate reduces processing cost, but does not study the utilization rate of metal material belt.
Invention content
