Embodiment 1

[0036] Refer to attached figure 1 , an integrated carbon fiber bicycle frame, comprising a front triangle 1, a seat stay 2 and a chain stay 3, one end of the seat stay 2 is provided with a first arc connector 21, and one end of the chain stay 3 There is a second arc-shaped connecting piece 31, and the first arc-shaped connecting piece 21 and the second arc-shaped connecting piece 31 are welded to the front triangle 1; the seat stay 2 and the first arc-shaped The connecting piece 21, the chainstay 3 and the second arc-shaped connecting piece 31 all use integral molding technology, and a reinforcing rod is arranged between the two brackets of the chainstay 2 and the chainstay 3 4.

[0037] In this embodiment, the integrally formed special rear upper fork 2 and rear upper chain 3 structure are used, and arc-shaped connectors are used to make the two firmly connected to the front triangle, reducing the number of connection points between components and increasing the number of co...

Embodiment 2

[0039] According to the vehicle frame structure described in embodiment 1, its processing technology comprises the following steps:

[0040] Step 1. Cut the carbon cloth by laser, and cut the raw material of the carbon cloth according to the demand;

[0041] Step 2, rolling;

[0042] The carbon cloth cut in step 1 is rolled on the mold layer by layer, and rolled into the front triangle, the rear seat stay and the rear seat stay, and the rear seat stay and the rear seat stay respectively. The lower fork is rolled together with the arc-shaped connector and the reinforcing rod; before rolling, it is necessary to make a 3D frame finished model and frame foam core model according to the structure and size of the frame, and according to the produced model Make corresponding finished molds, inner core molds and frame foam inner cores;

[0043] Step 3, preforming;

[0044] Put the parts rolled in step 2 into the inner mold and splice them into one, put them into the air bag, and wr...

Abstract

The invention provides an integrated carbon fiber bicycle frame and a machining process thereof. The arc-shaped connecting pieces are arranged at one end of a rear upper cross and one end of a rear lower cross. An integral forming technology is used for processing; the number of connecting points between the rear upper cross and the rear lower cross is reduced; a reinforcing rod is additionally arranged between the rear upper cross and the rear lower cross; and meanwhile, a frame produced through the machining process is simple in structure, various performance indexes can meet the requirements of the whole machine after testing and whole machine debugging, the machining process is simple, the cost is low, the reliability is high, and a powerful guarantee is provided for batch production.

Description

technical field [0001] The invention mainly relates to the technical field of bicycle frame processing, in particular to an integrated carbon fiber bicycle frame and a processing technology thereof. Background technique [0002] With the sustained and rapid development of my country's economy, the market demand for carbon fiber is increasing day by day, and the development of my country's carbon fiber I industry has great practical and far-reaching historical significance. Carbon fiber is a new type of fiber material containing more than 90% carbon. It not only has the inherent intrinsic characteristics of carbon materials, but also has the softness and processability of textile fibers. It is a new generation of reinforcing fibers. In addition to the characteristics of general carbon materials: high temperature resistance, friction resistance, electrical conductivity, thermal conductivity and corrosion resistance properties, etc., the shape has significant anisotropy, soft,...
