Automobile sliding door guide rail and processing process thereof

Abstract

The invention relates to an automobile sliding door guide rail and a processing process thereof, wherein the automobile sliding door guide rail comprises a guide rail body; the guide rail body is formed by bending a steel strip plate, a mortise sliding rail structure is formed in the length direction of the guide rail body, and reinforcing plates are integrally formed and fixedly connected to the two sides of the guide rail body respectively; and a high-strength coating is sprayed on the inner and outer surfaces of the guide rail body. The automobile sliding door guide rail is designed to be of the mortise sliding rail structure, when a sliding door is embedded in a mortise in the guide rail body in a sliding mode, compared with a traditional guide rail of a groove structure, the phenomenon that the sliding door falls off is not prone to occurring, the sliding door can stably slide in the guide rail, and the service life of the automobile sliding door is prolonged. And the reinforcing plates remarkably improve the mechanical property of the guide rail body, so that the guide rail body is not prone to deformation after being subjected to external force, and the structural strength of the guide rail body is improved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an automobile sliding door guide rail and a processing technology. Background technique [0002] Vehicle center door slide rail, commonly known as car guide rail, is the guiding and load-bearing component of the car sliding door. It is widely used in commercial vehicles with push-pull middle doors. It is an essential part of this type of vehicle. The structure is composite of PVC plastic and steel belt. The inner core of the product is steel belt, and the surface is covered with PVC plastic. Such a structure has the disadvantages of low surface material strength, easy damage, and complicated processing technology. [0003] In the existing technology, such as the Chinese patent whose publication number is CN106522714B, it discloses that the processing technology of the guide rail of the automobile sliding door includes preforming, sawing, forming, electrophoresis and installing...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned prior art scheme has the following defects: although the above-mentioned processing technology performs electrophoresis operation on the surface of the guide rail, the surface of the guide rail is coated with an electrophoretic paint layer, so that not only the appearance of the guide rail is beautiful, but also has good corrosion resistance

However, it has a groove-shaped structure as a whole, and its structural strength is low. After a long period of use, the limit edge is easily bent and deformed due to external collisions, so that the sliding door cannot slide stably in the guide rail. , reducing the service life of the car sliding door
