Description
Technical field
The present invention relates to the field of metal processing, especially a kind of stamping die for the production of air bag gas outlet.
Background technique
Air bag is the important component of automobile safety system.If vehicle crashes in the process of moving,
Sensor Receiving collision signal in air bag, reach when the collision alarm as defined in intensity after, gas generator ignites gas
Body propellant is unfolded air bag rapidly in a short time, thus the shape in front of passenger or driver to generate bulk gas
At air cushion layer, has the function that shock absorbing energy, personal safety is effectively protected.Therefore, can air bag fill in a short time
It is most important to meet enough buffer gas, and gunpowder explosion gas outlet plays decisive role to this.In order to guarantee substitute
Capsule can timely and effectively be unfolded, and need the wall thickness of strict control gunpowder explosion mouth central area cross cutting.Therefore it was producing
Cheng Zhong need to be tested or be monitored to cutting wall thickness to guarantee that central score wall thickness meets design requirement.It liquidates in the prior art
The measurement of die pressing product usually measures under line, i.e., dimensional gaughing is carried out to it after the completion of product, the inspection result of this mode has
Certain hysteresis quality can not find that in time product is bad, and stop stamping press, be easy to cause the significant wastage of resources of production.
In addition, part measurement method still uses manual mode to measure, the error of measurement result is larger.
Chinese invention patent CN201610686734.9 discloses a kind of stamping parts detection device, including tool skeleton, bone
Frame is equipped with substrate, fixes a sliding rail on substrate, sliding rail is slidably connected with a detection module.Detection module include sliding bottom,
Support base, returning face plate and detection block, one end of returning face plate and support base are rotatablely connected, and the other end and the detection block of returning face plate are fixed
Connection.Stamping parts is fixed on the detection position on substrate, returning face plate is rotated to horizontal position, detection block end face is made just to liquidate
The tested surface of casting die measures the gap between detection block and stamping parts tested surface by using clearance gauge, so that measurement obtains punching press
Part size.The detection module can be moved along sliding rail, and mobile detection module may be implemented to each critical positions of stamping parts
Detection.But on-line measurement when this method and unrealized punching press, measurement result have certain hysteresis quality, are finding product size not
When qualified, punching press can not be stopped in time, cause the significant wastage of resources of production.Also, this method is to be measured manually using clearance gauge,
Measurement error is larger.
Chinese invention patent CN201510088984.8 discloses a kind of online vision inspection apparatus of punch process and detection
