Abstract

The invention provides a production method of a rear fork part, and relates to the technical field of motorcycle production. The production method comprises the following steps that punching is conducted, specifically, one end of an edge pipe is placed on a first press machine to be pressed and fixed, and the edge of the other end of the edge pipe is punched by a punching device to form a semi-circular opening; necking is conducted, specifically, one end of the edge pipe is placed on a second press machine to be pressed and fixed, and the semi-circular opening of the edge pipe is subjected tonecking forming by a necking device; and welding is conducted, specifically, the rear fork part is formed by welding the edge pipe and a rear fork transverse pipe. According to the production method,the development and production cost of a notching die is reduced, and the production safety and production efficiency are improved; and the strength of the motorcycle rear fork part produced through the production method is improved, the appearance is flatter and smoother, and the attractive effect is improved.

Description

technical field [0001] The invention relates to the technical field of motorcycle production, in particular to a production method of flat fork parts Background technique [0002] The flat fork is one of the important parts of the motorcycle. In the prior art, the flat fork of the motorcycle includes two side tubes arranged symmetrically on the left and right and a transverse tube connecting the middle parts of the two side tubes (generally at the position where the side tube is close to one end of the frame). It is composed of tubes, and the whole is a left-right symmetrical structure. The flat fork part is located in the middle and lower part of the motorcycle, generally in the shape of an "H", and is installed between the frame and the axle of the motorcycle to play a supporting and connecting role. Among them, the ends of the two side tubes close to the frame are fixed on the frame through the shaft tube of the flat fork part. Specifically, a bushing for damping vibrati...
