Abstract
Differential spider squeezes pre- forging, including cylindrical body and along four axle journals of cylindrical body radial direction setting, four axle journals are arranged in cross, plane where the downwardly projecting Yu Sigen axle journal bottom of the bottom of cylindrical body, it is generally aligned in the same plane at the top of the top of cylindrical body and four axle journals, the bottom of cylindrical body is provided with the lower groove of bottom opening, and the upper groove of open top is provided at the top of cylindrical body.The utility model carries out the operation of squash type blocking to the blank after upset using extrusion die, the bottom and top of the cylindrical body of the pre- forging of differential spider squeeze as upper groove and lower groove, sub-material effect is improved when squeezing, the pillar of bottom setting cooperates in the lower die of lower groove and finish-forging die simultaneously, position pre- forging after squeezing the type of finish-forging die is intracavitary, in finish-forging, pre- forging will not be moved horizontally, to improve the qualification rate of pre- forging.
Description
Technical field
The utility model belongs to automobile part production technique field more particularly to a kind of differential spider squeezes blocking
Part.
Background technique
Differential spider is the important part of automobile drive axle, and specification kind is more, and demand is big.Existing differential mechanism ten
The pre- forging of word axis carries out blocking by the way of card pressure, and the pre- forging for blocking pressure is as depicted in figs. 1 and 2, is bulk-solid items structure,
The two sides of pre- forging body 1 are plane, pre- forging body 1 with a thickness of 80mm, the opposite two piece axis of pre- forging body 1
Neck 2 blocks the shorter of pressure, and the length between two axle journals, 2 end is 130mm.The pre- forging of this structure and size is carrying out finish-forging
It is had the following problems when operation:
1, since the two sides of pre- forging body 1 are plane, pre- forging body 1 is placed in the lower die 3 of finish-forging die
When, as shown in figure 3, pre- forging cannot position well, when upper mold pushes, pre- forging body 1 is easy to move, to worker's
Proficiency is more demanding, increases the operation difficulty of worker, lower so as to cause finish-forging qualification rate；
2, since pre- 1 thickness of forging body is thicker and axle journal 2 is shorter, larger workload when finish-forging is not only shortened
The service life of finish-forging die, and influence the production efficiency of finish-forging.
Utility model content
The utility model in order to solve shortcoming in the prior art, provide one kind have in finish-forging location structure,
The differential mechanism ten for improving finish-forging qualification rate, reducing worker operation difficulty, reduce finish-forging workload, extending finish-forging die service life
Word axis squeezes pre- forging.
In order to solve the above technical problems, the utility model adopts the following technical solution: differential spider squeezes pre- forging,
Including cylindrical body and along four axle journals of cylindrical body radial direction setting, four axle journals are arranged in cross, the bottom of cylindrical body
It is generally aligned in the same plane at the top of plane where downwardly projecting Yu Sigen axle journal bottom, the top of cylindrical body and four axle journals, circle
The bottom of cylinder is provided with the lower groove of bottom opening, and the upper groove of open top is provided at the top of cylindrical body.
The height of cylindrical body is 60mm, and the distance between two journal outer end portions being oppositely arranged are 190mm.
By adopting the above technical scheme, the utility model has the following beneficial effects:
The utility model carries out the operation of squash type blocking to the blank after upset using extrusion die, and differential spider is pre-
The bottom and top of the cylindrical body of forging squeeze as upper groove and lower groove, and sub-material effect is improved when squeezing, while recessed
The pillar cooperation that bottom is arranged in the lower die of slot and finish-forging die determines pre- forging after squeezing the type of finish-forging die is intracavitary
Position, in finish-forging, pre- forging will not be moved horizontally, to improve the qualification rate of pre- forging.Due to outside two axle journals being oppositely arranged
The distance between end is 190mm, is longer than existing 130mm, and the height (thickness) for allowing for cylindrical body in this way is reduced, i.e. cylinder
Blank Xiang Sigen axle journal at body punishes material.To make finish-forging workload mitigate, finish-forging efficiency is greatly improved.

Specific embodiment
As shown in Figure 4, Figure 5 and Figure 6, the differential spider of the utility model squeezes pre- forging, including cylindrical body 4 and edge
4 radial direction of cylindrical body setting four axle journals 2, four axle journals 2 in cross arrangement, the bottom of cylindrical body 4 it is downwardly projecting in
Plane where four 2 bottoms of axle journal, the top of cylindrical body 4 and the top of four axle journals 2 are generally aligned in the same plane, cylindrical body 4
Bottom is provided with the lower groove 5 of bottom opening, and the top of cylindrical body 4 is provided with the upper groove 6 of open top.
The height of cylindrical body 4 is 60mm, and the distance between two 2 outer ends of axle journal being oppositely arranged are 190mm.
The utility model carries out the operation of squash type blocking to the blank after upset using extrusion die, and differential spider is pre-
The bottom and top of the cylindrical body 4 of forging squeeze as upper groove 6 and lower groove 5, the raising sub-material effect when squeezing, at present
The pillar of bottom setting cooperates in the lower die 3 of groove 5 and finish-forging die, make after squeezing pre- forging intracavitary in the type of finish-forging die
To positioning, in finish-forging, pre- forging will not be moved horizontally, to improve the qualification rate of pre- forging.Due to two axis being oppositely arranged
The distance between 2 outer end of neck is 190mm, is longer than existing 130mm, and the height (thickness) for allowing for cylindrical body 4 in this way is reduced,
Blank Xiang Sigen axle journal 2 i.e. at cylindrical body 4 punishes material.To make finish-forging workload mitigate, finish-forging efficiency is greatly improved.
The present embodiment not makes any form of restriction the shape of the utility model, material, structure etc., all foundations
The technical essence of the utility model any simple modification, equivalent change and modification to the above embodiments, belong to this reality
With the protection scope of new technique scheme.
