Problems solved by technology

Most of these processes need to be done manually, and it is difficult to ensure the consistency of batch quality; in addition, the welding process will cause many welded joints in the bicycle frame itself. These welded joints not only have rough surfaces, reduce the strength of the frame, but also increase the Structural failure risk point, and the welding cost is also high, so that it not only affects the overall appearance of the bicycle, but also affects the safety performance of the whole vehicle

Abstract

The invention provides a bicycle frame which comprises a first frame body, a second frame body and a plurality of rib plates. The rib plates are arranged between the first frame body and the second frame body and used for enlarging the bearing force of the first frame body and the second frame body. The first frame body, the second frame body and the rib plates are integrally formed through extrusion molding. A central shaft installation part is arranged on the second frame body. The invention further provides a method for manufacturing the bicycle frame. The method includes the steps of material preparing, die heating, ingot casting heating, extruding, dragging, straightening and saw cutting. In addition, the method provides a bicycle comprising the bicycle frame.

Description

technical field [0001] The invention relates to the field of manufacturing bicycles and accessories thereof, in particular to a bicycle frame and a manufacturing method thereof. Background technique [0002] my country is a big country in the production and use of bicycles. For a long time, bicycles have always been used as the main means of transportation for people to travel short distances in the same city. As the main structure of the bicycle, the bicycle frame connects the various parts of the bicycle and plays an extremely important role in the entire bicycle. With the development of science and technology, the material of the bicycle frame has also evolved from traditional cast iron and steel to lighter materials such as aluminum alloy and titanium alloy. Because the bicycle of aluminum alloy material has advantages such as lightness, attractive in appearance, cheap, be subjected to liking of people always in recent years. [0003] In the prior art, the bicycle fra...
