Kinds of internal hollow materials are made of metal materials into a hollow hollow crank, which can be related to metal materials. More detailed and shape can be directly made into a scale-free processing-^ w γ various metals = hollow structure Products, for example, have reached the trend of light weight products since the second, and they have been constructed to achieve weight reduction. At present, they use the newer bicycle Republic of China Patent No. 368486 Manufacturing Method "invention patent case. It is a casting structure that first uses the mold; first it must be used first and then the inside of the mold is filled with a structure that melts the metal and is injected into the mold. In this way, it must be placed in the sand mold and heated. It is difficult to reduce the blank material of the hollow crank before the mold is opened. It is difficult to reduce the mass of the material. After the crank is formed, the sandy core of the crank is filled in the crank before the crank. The dug sand is dug out or the smooth running sand is usually difficult to be repeatedly recycled. Among the recyclable products, there are two-headed solid and inner cranks or exercise bike cranks. The inside of the crank must be hollow. The manufacturing method of the hollow crank can be found in “Cycle of hollow bicycle and its application method by 4 Shimano Co., Ltd., to obtain a mold of hollow crank blank to produce a sandy core, and to form the sandy hollow part of the crank Ruixin; 'To take out the hollow crank blank.

The pressing rod 31 is pressed against the metal material 20 from the original embryo / expanding cavity 133 with 10, and after a predetermined time, the metal material 20 is shown in the second figure ⑻. The bottom of the head cavity 132 is pushed through the Qiu ^ by the pressing rod 31, so that the metal material 20 fills and fills the entire shell die cavity 1 32, and because the pressing rod 31 continues to squeeze, the excess material That is, extending along the reserved gap between the squeeze rod 31 and the body cavity 131 to fill the entire gap and fill the expansion cavity 133 of the original embryo mold, a rough embryo 4 can be obtained. 〇. , As shown in the second (B) and third images, the rough embryo 40 has a first solid portion 4 which is formed in a spherical shape and is formed at the position of the head mold cavity 1 3 2. And 'a handle body 43 connected to the first solid portion 41 and formed by a reserved gap of the body mold cavity 31, the inside of the handle body 43 has a hollow formed by the squeeze rod exiting A slot 42 and a cylindrical expansion site 45 formed at the port 44 by the expansion cavity 133. Then, a liquid filling material 50 is poured into the hollow slot hole 42; the filling material 50 has a characteristic of being solid at normal temperature and being liquid when heated to a predetermined temperature; in this embodiment, the filling material 50 may be It is made of waxy material. When heated to a temperature of about 70 t to 80 ° C, it forms a liquid. As shown in the fourth figure, 'it can be easily poured into the hollow slot 42, and the operation is quite convenient. 'The filler 50 is cooled, and when it returns to normal temperature or a predetermined temperature, it turns into a solid state and accumulates and is embedded in the hollow slot 42. The rough embryo 40 is repeatedly closed at a predetermined position near the port 44 so as to form a second solid portion 46, and the filler 50 is closed inside the hollow slot 42. ; As shown in the fifth figure, in this embodiment

The standard object 50 is a stable limit. Next, the solid part 41 and the second tool 60 are integrated. The stamping die is further provided with a forging punch that is generally a self-pressing die 60 and is filled in the hollow slot 42. The moment of forging During the punching process, the round-shaped expansion part 45 is closed in a closed manner, and the closing process is performed to make the bundle closed to form a filler 50 close to the port 44 in the predetermined circumference of the closed hollow slot 42 or to a completely closed system. In the closed hollow type processing, as shown in the sixth figure, the crank thick tool 60 of the solid part 46 has an outer edge of the upper die 61 or the second solid part of the cylinder, and the processed part is covered, as shown in the slot 42. The embryo 40, and the mold cavity 63 of the appearance of the car crank.

Description of the invention (7) Outflow; Of course, you can also use hot air to spray from one of the through holes 75. The hot air that is accelerated and pressurized by high temperature is good for the outflow and cleaning of the liquid filler 50. 'Finally, the through hole 75 can be repaired to obtain the complete appearance of a bicycle crank 70. The above is an overview of the steps and technical characteristics of the method for manufacturing a double-headed solid hollow metal material according to the present invention. Then, the effects expected of the present invention are described as follows: The present invention is technically made into a metal rough and solid part. Among them, the hollow slot state, and then the heart, and then set out through a predetermined number of channels, so that the waste of manpower of the conventional bicycle of the present invention can reduce costs even more. The invention can be provided by wax material and can be used for irrigation. The inside of the handle body is filled with open ends through the shaping hole, and then a double crank is manufactured to increase the working time, and the double material is added to make the injection operation embryo. The handle is filled with liquid, and the handle is heated to make the double head. Solid head inside the solid crank, and the industrial head can be solid, which is filled and processed inside the body to form the heart of the curved solid. The hollow part is removed from the sand. The hollow hollow part is heated to the inner part. The hollow metal material in the shape of the filling part of the shank is inserted into the heart of the sand. The metal material is pre-heated. The metal material is pressed to the center of the core and connected to the first hollow slot. After it is cooled, it forms a solid bundle to form a second solid shape, and then drills into a liquid form on its shank. The finished metal material of the through hole. Method, because there is no need to waste materials such as sand cores, the method 'its filling system is formed into a liquid state, and the mouth is restored to normal temperature or a predetermined support structure to support the load' is made of waxy material The resulting filler changes to a solid state at temperature, making it sufficiently

Description of the invention (8) When forging, stamping or closing, the accuracy of the shape and size of the product is effectively exerted. Moreover, the solid state is made of waxy material to make it liquid, which is more conducive to flowing out of the slot. In addition, the waxy filler is relatively cheap, and the recycling of the material is used, which has significant industrial utility value. Various early molds can be set for simultaneous processing of multiple objects at the same time, which can reduce production costs. Stomach ^ In summary, the present invention is practical in similar products. At the same time, it has not been found that the same technology exists in domestic and foreign countries for such structures.
