AI Technical Summary

Technical Problem

After the polishing and grinding process of the vehicle-mounted cover plate, the difference in depth of the tempered layer on both sides exceeds the standard range, resulting in the arch size exceeding the required standard range and becoming a bad product.

Method used

The defective products are re-renovated by secondary tempering, shaped arch facet measurement and flat grinding polishing. The specific steps include secondary tempering of the defective product, measuring its convex surface and concave surface, and making the depth of the convex surface tempering layer equal to or close to the depth of the concave surface tempering layer through a polishing device.

Benefits of technology

Through the above steps, the shaped arch of the vehicle-mounted cover can be repaired to the standard range, reducing losses, and improving product quality and accuracy.

Abstract

The invention discloses a vehicle-mounted cover plate arch repairing method which comprises the following steps: secondary tempering: carrying out secondary tempering operation on a cover plate defective product to increase the tempered layer depth of two side surfaces of the cover plate defective product so as to form a secondary tempered cover plate; the secondary tempered cover plate is measured through a measuring tool, and the convex face and the concave face of the secondary tempered cover plate are separated; and flat grinding and polishing: placing the secondary tempered cover plate on polishing equipment with the convex surface facing upwards, and polishing the secondary tempered cover plate through the polishing equipment, so that the depth of a convex surface tempered layer of the secondary tempered cover plate is equal to or infinitely close to the depth of a concave surface tempered layer. According to the vehicle-mounted cover plate arch repairing method, secondary tempering, arch faceting and flat grinding polishing are sequentially carried out on the cover plate defective product, and therefore the arch of the cover plate defective product is repaired to be within the standard range. Therefore, the vehicle-mounted cover plate can be repaired, and loss can be reduced.
