Abstract

The invention discloses a bus seat processing technology. The bus seat processing technology comprises the following steps that P1, injection molding is carried out by adopting raw materials to obtaina seat blank; P2, surface finishing is carried out on the seat blank to obtain a treated blank; P3, surface treatment and shaping are carried out on the treated blank to obtain a process product; P4,size and hardness detection is carried out on the process product according to design requirements to obtain a primary survey product; P5, subsequent drilling and tapping processing are carried out on the primary survey product to obtain a finish product; and P6, accurate detection is carried out on the finish product, and a seat product is obtained after the finish product is qualified. The busseat processing technology adopts high-toughness polystyrene material, the structural strength of plastic products can be effectively improved, and the surface performance is good; and after the injection molding is completed, annealing treatment is carried out firstly, then a coating layer is sprayed, the surface hardness and the wear resistance are improved, the process is simple and easy to operate, the production cost is effectively reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of seat processing, in particular to a process for processing a bus seat. Background technique [0002] In today's daily life, the bus is the most used by people for daily travel, and the seats inside the bus are generally made of plastic, which is light in weight, good in appearance, and poor in thermal conductivity, which is conducive to ensuring comfort. [0003] However, the proportion of raw materials used in the processing of existing bus seats is unreasonable, resulting in poor structural performance and strength of bus seats, which are easy to break and break, and Jiang Gong's process is too complicated, which affects production efficiency, and the surface hardness of the seat is poor. It is easy to scratch, affects the aesthetics, and has a short service life. Contents of the invention [0004] The purpose of the present invention is to solve the shortcoming existing in the prior art, and propose...
