Description of the invention: [Technical field to which the invention pertains] The improved method for the axial center of the present invention is based on various axial shapes, and the main body portion which is difficult to process is forged into a shape to directly form a hollow secret. Then, the rod body is connected to form a body to provide the axis of the desired shape, and the technical field is easy to process, save waste, and reduce the defect rate. [Prior Art] • According to each record, I crane's current fair forging is the main reason for the processing of the fuel lathe. However, due to the forging of the shaft, the size of the mold is relatively bulky, and the mold is relatively cumbersome. If there is such a machine, it will be a fabulous thing, and if it is meager, it will cost a lot of money, and it will be lighter and clearer. For the sake of convenience, the processing procedure of the piston axis is taken as an example. Your review board is easy to understand. Please refer to the m map and the third rider. As you can see, the φ active base shaft ~ structure 1 'is usually made by the automatic lathe machining, and the metal rod body is directly made into the annular main body portion 11 and the long rod portion 12 The basic configuration (refer to the first figure), and then the drilling tool A is drilled from the axial end surface of the long rod portion 12, and a circular hole 13' penetrating to the end position of the main body portion n is drilled. Forming; only the piston 1 made of metal rod 1 brakes has a lot of vehicle scraps (see the first figure), which not only has the trouble of scrap cleaning, but also the waste generated by molding. The cost is increased, so the formability is rather uneconomical; in addition, the distance from the end of the long rod portion 12 to the end portion of the main body portion is quite long, and the direct drilling of the round hole 13 is caused by the resistance of the cutter A being too large. 1272154 There is a problem of inconvenient processing 'plus long-distance drilling is not easy to control the cancer.' Therefore, its non-performing rate must be biased to ifj, which is the main reason for its cost: L time, labor and cost. [Summary of the Invention] -, the problem to be solved: 1, the shape of the self-scale bed plus jade, is directly made of the metal rod car into the required _ shape 'known piston to process directly to complete the structure of the body , two plus _ process will form a considerable amount of car waste, not only the waste cleaning is not easy, the problem of ϋ 更 更 该 该 该 废料 废料 废料 废料 废料 废料 废料 废料 废料 废料 废料 废料 废料 废料 废料 四 四 四 四 四 四2. The round hole 13 is controlled based on the long-distance drilling, so it is often difficult to form due to the hole-to-hole or drilling. ^ * Easy to form the addition of I, there will be labor and time-consuming missing, the material defect rate of scrapping and recording waste, will cause the cost of thieves to sink. Second, the means to solve the creation of the use of the desired The shape of the shaft is blueprinted. The main body that is difficult to machine is forged by forging, so that the shape and the inner hole are formed one by one, and then processed separately to improve the precision and waste waste. 2. The volume of the main body is small, which can be achieved by a small mold and a small machine, which saves working space and cost. ^ • Its enchanting rod is taken from the existing specifications, and the shirt can be directly processed by friction welding. It can only be processed without waste materials, up to 3 1272154. Age-age, community and pole view

The result of the production is simplified (the fourth process is simplified) and the finished casting is low, and a large number can be provided. [Implementation] Please refer to the fourth and fifth figures. As shown in the sixth and seventh figures, the present invention is an improved method for the shaft, which is mainly used for the vehicle, which is used to form a main body 21, which is a hard-to-machine part. The type of the sturdy and the rim is also the same, and the length of the rod with the same outer diameter as the outer diameter of the flange is exposed to the external frictional connection method of the fourth figure, so that the end face of the rod (four) and the phantom edge of the main body are strong. The frictional stagnation side S, the secret of the 23th ^ t into the inner hole 将 when the metal scraps S completely washed out (refer to the sixth figure), thousands of J where the essence 22 and the king body 21 combined into - The fineness of the body 2 (see the fifth figure and the first, as shown in the figure), the knot turning degree is the same as the live silk forming of the body marriage, and thus the painful processing and the reduction of the defect rate, and the rapid forming. The piston shaft 2 of the embodiment is not limited to the piston shaft type, but various shafts such as the transmission shaft (such as the '), can also be manufactured by the method of first, the main body is magical, forged, The portion that can be processed in the same manner can be directly forged in this way, so as to reduce the waste and processing time, and reduce the cost, and then cooperate with a rod 22 having an outer diameter corresponding to the connecting end 211' of the main body sinking 1272154. ', the friction welding is directly combined into one, and the molten scrap outside the welding position is processed and removed to form a complete transmission shaft and provide the same strength as the integral molding. 1272154 [Description of the schema] The first diagram: the basic configuration diagram of the conventional structure.
