Embodiment 1

[0040] Example 1 as figure 1 , figure 2 , image 3 Shown, a kind of manufacturing method of integrally formed bicycle frame, its step comprises:

[0041] (1) Production of modular wax parts for the overall frame.

[0042] The module wax parts include vehicle frame wax parts and process wax parts, wherein the vehicle frame wax parts include front triangle wax parts 111 and rear triangle wax parts 112, first make the front triangle wax parts 111, assemble and weld the rear triangle wax parts 112, and then Make the craft wax piece, then weld the front triangle wax piece 111 and the craft wax piece to obtain a complete module wax piece.

[0043] Wherein, in step (1), the overall frame wax is welded by a frame wax component that can be conveniently press-injected to form an outer contour with a molding material, and form an inner cavity by pressing or a core. Described vehicle frame wax part is made up of five parts of front triangle wax part 111, left and right flat fork wax pa...

Abstract

The invention provides a making method of an integrally formed bicycle frame. The method comprises the following steps: making a frame wax member and a process wax member, welding the frame wax member and the process wax member to form an integral module wax member, making a shell, dewaxing, baking, carrying out casting formation, and carrying out cleaning and polishing to obtain the integrally formed bicycle frame. The frame is divided into a plurality of assemblies, so the making process of the frame wax member is simplified, and the method can be widely used in integral formation of various bicycle frames without restriction by the structure, the dimension, the weight and the chemical components of the frame; no welded joints exist among all parts of the whole frame, so the whole frame has beautiful and simple profile, and the fatigue rupture resistance is improved; and the integral forming method is adopted, so the production efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of bicycle manufacturing, in particular to a method for manufacturing an integrally formed bicycle frame. Background technique [0002] Bicycle is a kind of green transportation tool and also a kind of exercise and fitness equipment, and its demand at home and abroad is huge. In the prior art, the bicycle frame is welded together with the frame pipe and joint pipe fittings to form an integral vehicle frame. This process method produces many welded joints on the frame itself. The welded joints not only affect the overall aesthetics of the bicycle, but also the structure of the heat-affected zone of the welded joints is very uneven, which becomes the source of failure of the entire frame, and the ability to resist fatigue damage is reduced. These welded joints will be advanced in the subsequent quality test and use damage, the service life is reduced, and it brings potential safety hazards to riders. [0003] In orde...
