The airbag walnut wood grain cover plate is made by reserving a plastic hollow riveting column on the back of the decorative panel, and then riveting it together with a stamped thin metal plate skeleton. The airbag walnut wood grain cover plate perfectly combines the surface easy handling characteristics of plastic parts with the rigidity of the stamping metal skeleton, with good elasticity, no sharp edges and corners, uniform stress distribution, simple and light structure, etc., when encountering accidental collision, the product can still maintain the integrity of the structure, will not produce sharp fragments, not only can play the role of anti-collision and energy absorption, but also effectively reduce the consumption of materials, reduce the weight of the body, thereby providing better safety protection.

The upper part is a hollow riveting column (tubular hot pile) to ensure the strength of the fastening connection, and the lower part is a long rib wing rib rib, which can provide a gap of expansion and deformation while ensuring the connection strength, so as to facilitate the assembly of the curved surface structure. By combining the hollow riveting column flanging riveting with the ribbed vertical rib riveting, the elasticity of the plastic parts and the rigidity of the metal structural parts with the ability to resist deformation are perfectly combined, forming a collision resistant airbag assembly that is both lightweight and strong, and highly safe and reliable. The component has been tested under extremely harsh conditions and harsh environments, and is able to fully absorb the impact force in the event of an accidental impact; In the event of an emergency, the airbag is able to pop out quickly, thus greatly improving the body of the vehicle.

The application of riveting technology in the internal circuit of the roof light in the car. The reserved riveting post on the plastic seat of the roof lamp in the car passes through the pre-punching hole on the metal sheet, and then the hemispherical round cap is used to rivet the metal sheet conductor, and the vertical rib is used to isolate the parallel metal sheet to insulate it and rivet the upsetting head, which can effectively prevent the metal sheet conductor from vibrating and falling off, and fundamentally eliminate the short circuit phenomenon.

Various functional interior parts (such as audio grid grille covers, door handles, elbow rests, storage boxes, leather interior components, etc.) are riveted to the door frame molded from wood powder board or fiber laminate, which can achieve the functions of light weight, low price, sound insulation and heat preservation. The riveting process for the door trim is to first install the door trim in place on the door bone

frame, and then clamp them on the mold, the turntable type three-station door panel interior plastic riveting welding machine can make the back riveting posts (hot piles) located in different planes complete the riveting of each riveting point at the same time in one action. In this way, it can not only ensure the uniform distribution of forces, but also avoid local stress concentration, so that the overall structure of the door skeleton is firm and reliable, and can withstand the test of long-term severe vibration and environmental climate change.

Shown is a speaker cover grid assembly riveted to a molded laminated wood chalk door frame. In this application, the riveting method of hollow core riveting column turned outward is adopted, which has the characteristics of high connection fastening strength, single process and high production efficiency. The riveted speaker cover grid assembly can effectively avoid the influence of vibration and noise during driving, and the silent noise reduction effect is good, which can achieve high fidelity and high power output.
