Problems solved by technology

[0010] 1. The steps are cumbersome
Requires multi-step close fit, resulting in a lot of time cost
[0011] 2. Low degree of automation
Each step requires a lot of manual production. With the current technical conditions, it is not easy to realize automation, so a lot of labor costs are generated.
[0012] 3. Low standardization rate
There are many manual operations, so it is not convenient to carry out more detailed standardization requirements, and it is not convenient to control product quality, so the product standardization rate is low
[0013] 4. Low quality control
The manual operation is uneven due to the technical level of the workers, and it is impossible to keep each batch of products relatively consistent, so the product quality control is low

Abstract

The invention relates to the technical field of bicycle production, in particular to a method for producing a bicycle frame through a three-dimensional printing technology. The method includes the following steps that A, the frame is divided into a plurality of structural members which comprise a head pipe, a plug-in side plate, an upper pipe and a lower pipe which are all arranged to be of plug-in structures; B, the three-dimensional printing technology is used for standardized production of each structural member; and C, the upper pipe and the lower pipe are connected with the head pipe in a plug-in manner, and then the whole is connected with the plug-in side plate in a plug-in manner. By means of the method, operation is simple, the product yield is high, the production process is high in automatic degree, the product quality is easily controlled, the standardization level is high, and the product quality is stable.

Description

technical field [0001] The invention relates to the technical field of bicycle production, in particular to a method for producing bicycle frames using 3D printing technology. Background technique [0002] Due to the single processing method of the traditional carbon fiber bicycle frame, its structure is mostly a one-piece structure. The frame production process is generally as follows: [0003] 1. Make the bicycle frame structure section. Divide the bike frame into structural sections such as seat tube, head tube, bottom bracket, dropouts, etc. After processing different structural sections into metal molds, according to the shape of each structural section, use the method of manual lamination layer by layer to paste carbon fiber cloth on the inner wall of the mold, then close the mold, pour resin liquid, and become an independent structural section after curing . [0004] 2. Make the support frame. Make a support frame for a complete frame, which can ensure the accura...
