Description of the invention (|) The present invention relates to a method for manufacturing a hollow composite crank of a polymer composite material, especially a lightweight crank produced by it And a practical method with good tensile strength and buckling strength. At present, the common manufacturing process of bicycle crank structure is that the aluminum alloy material is first extruded and cut, and then heated to a temperature above the deformation temperature in advance, and placed in a molding die to forge a solid crank contour shape. After finishing the surface trimming, drilling and tapping, the finished crank is finished. However, 'the crank structures produced by this conventional crank manufacturing method are solid, although the whole is made of aluminum alloy' and the specific gravity of aluminum alloy material is already higher than that of stainless steel or cast iron cranks Lighter 'but its solid structure design will still cause excess crank weight' and there is the disadvantage of being overweight. In particular, the bicycle structure requires lightness and good handling, so the excess crank weight Will cause the overall weight of the bicycle to increase, affecting the lightness and handling performance of the bicycle "" In view of this, the inventor has devised the manufacturing method of the bicycle hollow crank of the polymer composite material of the invention to provide a weight that can be produced A method for manufacturing a crank that is lightweight and has excellent tensile strength and buckling strength. The main purpose of the present invention is to provide a method for manufacturing a hollow crank of a bicycle which has light weight and excellent tensile strength and buckling strength. The horizontal cross staggered between the two aluminum cylinders, and the outer side is affixed with a woven cloth patterned polymer composite material, which is covered with an air bag.

Through the above process design, the crank produced by the method for manufacturing the hollow composite crank of the polymer composite material of the present invention has the following advantages: 1. The crank produced is light in weight: because the whole is made of unidirectional polymer composite material And woven cloth pattern polymer composite material, and the molecular weight of the South molecular composite material is far lighter than that of the Shao alloy, and when the crank is formed, the interior is hollow, so it can effectively reduce the production Crank weight. 2. Good tensile strength: Because the unidirectional polymer composite material surrounded by each path is in the longitudinal and lateral interactive winding pattern, and both sides of the crank are provided with a woven fabric polymer composite material, the polymer The composite material itself has excellent tensile strength, so when the polymer composite material intersects with each other vertically and horizontally, it can make its tensile strength in all directions good. 3. The buckling strength is all good: Because the unidirectional polymer composite material surrounded by each path is in a longitudinal and horizontal interactive winding pattern, and the woven fabric polymer composite material is pasted on both sides of the crank, not only the Improve the impact resistance of the surface, and excellent resistance to buckling 9 4 · Good appearance: Because the two sides of the crank are woven with a woven fabric polymer composite material, the surface has a weave that intersects vertically and horizontally To improve its overall visual beauty. 5. The sleeve can be processed separately: Because the sleeve has a round and small size structure, the processing accuracy is higher during processing, and the positioning of the fixture with high precision is higher than (21〇χ 297 hair)-[IK — — — — — — — I ------ Order -------- I < Read the notes on the back before filling out this page> 4 6 1 8 6 6 A7 ~ ^ --- -——----_______ 5.
