Production process of carbon fiber bicycle frame

Abstract

The invention discloses a production process of a carbon fiber bicycle frame, and relates to the technical field of machining of bicycle frames. The production process comprises the steps that a three-dimensional drawing model of the bicycle frame is established; the three-dimensional drawing model is input to a 3D printer, and a real bicycle frame model is obtained through 3D printing operation;fragile points are set on the real bicycle frame model; prepreg cloth pieces are laid on the real bicycle frame model layer by layer in different directions and in different sequences and then are compacted; the whole real bicycle frame model laid with the prepreg cloth pieces is placed into a forming mold for solidification and formation, so that a blank is formed; the blank is separated from themold, so that the carbon fiber bicycle frame is obtained; and finish machining is conducted on the carbon fiber bicycle frame. According to the production process, the 3D printing method is adopted for the whole bicycle frame, so that the defect that molds are needed for machining bicycle frames in the prior are is overcome; glue-based assembling is not needed, so that the production steps are simplified, the production efficiency is high, the integration degree is high, and the strength of part joints is high.

Description

technical field [0001] The invention relates to the technical field of bicycle frame processing, in particular to a carbon fiber frame production process. Background technique [0002] The bicycle industry has a history of more than 100 years. The demand for bicycles around the world remains at the level of 106 million units per year, and the annual transaction volume of bicycles is about 5 billion US dollars. As the income levels of people around the world increase, the global demand for bicycles will further expand. With the further structural upgrading of bicycles, it will bring greater profit margins to industry participants, and the development prospects of China's bicycle industry will also be broader. . [0003] Traditional bicycle frame materials are carbon steel, chrome-molybdenum steel, aluminum alloy, titanium alloy, etc. The conventional process flow is: tube blanking processing + welding forming + correction. Welding process is required in each process, which l...

Problems solved by technology

The accuracy of this process mainly depends on the machining accuracy of each mold, and the design and manufacture of multiple molds is relatively cumbersome. Many frame structures are difficult to process and shape at one time, and they need to rely on subsequent cutting processes, making the entire processing process longer. At the same time, the gluing process makes the strength of the joints of the components lower, the production efficiency is low, the dependence on skilled workers is high, and the product defect rate is high, which is not conducive to automatic production and increases production costs.
