AI Technical Summary

⚠Technical Problem

In the existing technology, the riveting structure of hardware and plastic parts is prone to cracking at the salad hole position of the plastic parts after riveting, resulting in a defect rate of up to 20% and affecting the service life of the product.

⚗Method used

Design a riveting and forming structure for hardware and plastic parts. A bud is set on the bending plate of the hardware part. The bud passes through the vertical section of the plastic part and is riveted to the inclined section. The opening angle of the inclined section is 120°±5°, the height of the vertical section is 0.25±0.13mm, the hole diameter is X±0.05mm, and the outer diameter of the bud is (X-0.2)±0.05mm. To avoid hard contact, an arc chamfer design is adopted.

🎯Benefits of technology

This effectively reduced cracking of the salad holes at the riveting locations, improved the yield rate, and extended the product's service life.

Abstract

The utility model discloses a hardware and plastic piece's riveting pressure forming structure, including hardware, first plastic guide rail and second plastic guide rail, and the both sides forming of hardware have the bending plate, and the bending plate is formed with the sprout on, and first plastic guide rail and second plastic guide rail all are provided with salad hole, and the vertical section and the inclined section are provided on the salad hole, and the sprout riveting pressure is in the inclined section after passing through the vertical section, and the vertical section is communicated with the inclined section, and the opening angle of inclined section is R, wherein R is 120 DEG +0 / -5 DEG, and the height of vertical section is h, wherein h is 0.25+0.13mm, and the aperture of vertical section is X, wherein X+0.05mm, and the outer diameter of sprout is phi, wherein phi is (X-0.2)+0.05mm. The hardware and plastic piece's riveting pressure forming structure reduces the height of vertical section, so that sprout does not press to the vertical section in the process of unfolding riveting pressure, and the plastic piece will not crack when the hardware and plastic piece do not produce rigid contact, maintains the good use state, prolongs the service life of structure.
