Abstract
The invention provides a process for manufacturing transmission shafts of automobiles. The process includes mixing raw materials; pressing the raw materials to obtain preformed blanks; sintering the preformed blanks until the preformed blanks are completely alloyed to obtain sintered bodies; carrying out hot forging on the sintered bodies instantly to obtain initial blanks after the sintered bodies are manufactured; carrying heat treatment and shot blasting treatment on the initial blanks to obtain finished products. The transmission shafts of the automobiles comprise components by mass percents. The process for manufacturing the transmission shafts of the automobiles has the advantages that the rigidity, the hardness and the flexibility of the transmission shafts can be improved, and the transmission shafts are high in torsion resistance.
Description
Technical field
The present invention relates to a kind of manufacturing process of truck drive shaft, belong to Manufacturing Technology for Automotive Parts field.
Background technology
The requirement of truck drive shaft is general higher, and surface quality requirements is high, and rigidity toughness requires high.
Summary of the invention
The invention provides a kind of manufacturing process of truck drive shaft, can improve the rigidity of power transmission shaft, hardness and suppleness, is that its anti-twisting property is strong.
In order to solve the problem, the technical solution used in the present invention is: a kind of manufacturing process of truck drive shaft, comprises the steps:
A, batch mixing: described truck drive shaft is made up of the component of mass percent:
B, compacting: described raw material is pressed into preform;
C, sintering: described preform is sintered to complete alloying, obtains sintered body;
D, forge hot: after described sintered body makes, carried out forge hot process immediately, obtain just base;
E, by described just base after heat treatment, bead, obtain finished product;
Intercept the raw material of the thick Steel Bar in the same transmission shaft lever portion etc. of certain length as power transmission shaft; Choose the raw material of flange blank as flange; Flange blank is carried out turning, processes the positioning reference plane required for flange surface precision drilling and clip position, then carry out holing, chamfering and drill centers; Flange good for fine finishining is crimped into whole truck drive shaft with power transmission shaft raw material by friction welded equipment; Whole power transmission shaft carried out turning, rub spline with the hands, be heated to 750-890 DEG C by intermediate frequency equipment and heat-treat, rear water-spraying control, more whole power transmission shaft is inserted the tempering furnace lonneal of 190 DEG C, then alignment is carried out to whole power transmission shaft; The grinding of power transmission shaft finish turning and rust prevention packaging: after whole power transmission shaft after alignment being carried out finish turning and being ground to required size, carry out antirust treatment, then pack warehouse-in.
Further, in described step c, the equipment adopted when preform sinters to complete alloying is sintering furnace; Environment during described preform sintering is oxygen-free environment; Temperature during described preform sintering is 600 ~ 650 DEG C, and the time is 30 ~ 45min.
Further, in described steps d, the forge hot process of sintered body carries out in grinding tool; Temperature during forge hot process is 1100 ~ 1180 DEG C, and pressure is: 600 ~ 650MPa.
The manufacturing process of this truck drive shaft that the present invention relates to, can improve the rigidity of power transmission shaft, hardness and suppleness, is that its anti-twisting property is strong.
