Existing automotive transmission input seniority among brothers and sisters carrier, is used in inside automobile gearbox, fixed Planetary Gear Transmission.Product plane is bad, product separating force does not reach the problems such as requirement, product size do not reach requirement after claw crackle, sintering, it is impossible to produce in enormous quantities.
The content of the invention
Goal of the invention：For the deficiencies in the prior art, it is an object of the invention to provide a kind of automotive transmission input seniority among brothers and sisters carrier, with high-precision size, firmly welding, meets use demand.
Technical scheme：In order to realize foregoing invention purpose, the scheme that the present invention is used for：
A kind of automotive transmission input seniority among brothers and sisters carrier, including planet carrier body and flange, described planet carrier body and flange are by the integrally welded structure of solder, and the integrative-structure is the polymorphic structure that the planetary gear structure shape being matched therewith matches, and planet hole is provided with integrative-structure.
The powder metallurgy of the speed changer input seniority among brothers and sisters carrier, which is constituted, is：Fe：Surplus；Cu：1.5~3.9%；C：0.3~0.6%；Other inevitable impurity are no more than 2%.
The density of the speed changer input seniority among brothers and sisters carrier is in 6.8 g/cm3 More than, perpendicularity：Below 0.036mm, cleannes：Below 1.09mg, takes off pull out force：More than 10000N, position degree：0.04 below mm.
The preparation method of described automotive transmission input seniority among brothers and sisters carrier, comprises the following steps：
1）Draw materials, flange is under the effect of 750T hydraulic presses, and planet carrier body is formed separately under the effect of DORST 500T hydraulic presses in water cooling mold；
2）Flange and planet carrier body are sintered into one with solder in continuous sintering furnace, 1130 DEG C of sintering temperature 4 section, guipure speed 120mm/min, atmosphere RX；
3）Use ultrasonic drilling machine full inspection planet carrier claw crackle；Humorous resonance machine full inspection whether solder skip material；
4）Using two end faces of lathe grinding product, machining center milling planet hole is used；
5）The residual at solder is removed using multiaxis special plane；
6）Use laser inscription machine engraving product ID and Quick Response Code；
7）Ground using oscillating mill, remove product surface burr；
8）Product examine；
9）The magnetic that product process is related to is eliminated in degausser；
10）Cleaned in rinsing machine, medium is water dispenser solution, is sprayed；
11）Packaging, shipment.
Beneficial effect：Compared with prior art, automotive transmission of the invention input seniority among brothers and sisters carrier, the planet carrier is made up of planet carrier body, flange and the part of solder three.Planet carrier body is that have the normal production of 750T shapings, flange is the shaping of DORST 500T hydraulic presses, wherein planet carrier body, flange it will weld together through oversintering, after the completion of sintering, solder will be melted between planet carrier body and flange, and product size and line position tolerance are ensured by machining, efficiently solve the high-precision Assurance of Size of powder metallurgy, local density of powder metallurgical product is inconsistent, the firm welding of two company single-pieces, with high-precision size, the features such as firmly welding.With good practicality.
Brief description of the drawings
Fig. 1 is the structural representation of automotive transmission input seniority among brothers and sisters carrier；
Fig. 2 is the sectional view of automotive transmission input seniority among brothers and sisters carrier.
Embodiment
With reference to specific accompanying drawing, the present invention will be further described.
As shown in figure 1, automotive transmission input seniority among brothers and sisters carrier, including planet carrier body（spider）1 and flange（flange）2, planet carrier body 1 and flange 2 pass through solder（braze）Integrally welded structure, the integrative-structure is the polymorphic structure that the planetary gear structure shape being matched therewith matches, and planet hole 3 is provided with integrative-structure.The powder metallurgy of automotive transmission input seniority among brothers and sisters carrier, which is constituted, is：Fe：Surplus；Cu：1.5~3.9%；C：0.3~0.6%；Other inevitable impurity are no more than 2%.
The preparation method of automotive transmission input seniority among brothers and sisters carrier, comprises the following steps：
1）Draw materials, flange 2 is under the effect of 750T hydraulic presses, and planet carrier body 1 is formed separately under the effect of DORST 500T hydraulic presses in water cooling mold；
2）Flange and planet carrier body are sintered into one with solder in continuous sintering furnace, 1130 DEG C of sintering temperature 4 section, guipure speed 120mm/min, atmosphere RX；
3）Use ultrasonic drilling machine full inspection planet carrier claw crackle；Humorous resonance machine full inspection whether solder skip material；
4）Using two end faces of lathe grinding product, machining center milling planet hole 3 is used；
5）The residual at solder is removed using multiaxis special plane；
6）Use laser inscription machine engraving product ID and Quick Response Code；
7）Ground using oscillating mill, remove product surface burr；
8）Product examine；
9）The magnetic that product process is related to is eliminated in degausser；
10）Cleaned in rinsing machine, medium is water dispenser solution, is sprayed；
