Description
Technical field
The present invention relates to automobile parts processing technique field, specially a kind of vehicle rear-axle housing and its processing technology.
Background technique
In automobile parts, it is that casting or steel plate are welded that vehicle rear-axle housing, which processes common method, both add
In place of work method all Shortcomings, casting manufacturing process is more complicated, and the process-cycle is long, and yield rate is low, and steel plate weldment welds
The steel for meeting place are more crisp after high-temperature soldering, and problem is easy to appear in use, research and develop a kind of new vehicle rear-axle housing and its
Processing technology is highly desirable to manufacturing process and raising product intensity is simplified.
Summary of the invention
The purpose of the present invention is to provide a kind of vehicle rear-axle housing and its processing technologys, to solve to mention in above-mentioned background technique
Out the problem of.
To achieve the above object, the invention provides the following technical scheme:
A kind of vehicle rear-axle housing, the differential carrier including intermediate approximation spheroidal, the left arm and right arm at differential carrier both ends are described
Differential carrier upper and lower surface is provided with symmetrical holes, the left arm and right arm as thick-walled pipe composition, and the arm end far from differential mechanism is straight
Diameter is less than intermediate caliber.
Preferably, the vehicle rear-axle housing is made of a heavy wall round steel pipe overall processing.
A kind of vehicle rear-axle housing, processing technology include the following steps:
Step 1: blanking: selection material be Q345,160-180 millimeters of diameter, the round steel pipe that 12-15 millimeters of wall thickness, by a scale
Very little severing.
Step 2: Su Guantou: carrying out the draw to predetermined size to round steel pipe both ends on machine for shrinking.
Step 3: opening: position symmetrical above and below respectively processes a rectangular opening, 120 millimeters of X40 millis of size among round steel pipe
Rice, size 120 are length of steel pipe direction.
Step 4: reaming: conical steel pricker being pressed into rectangular opening middle position with press machine, so that rectangular opening middle section
It expands outwardly and is deformed into circle hole shape.
Step 5: bulging: the dedicated bulging tool every two being made of four heads that rise symmetrically is put into middle circle hole site,
Four heads that rise are pulled out simultaneously with four hydraulic cylinders, hydraulic cylinder pull direction is divided into along round steel pipe length direction and perpendicular to circle
Length of steel pipe direction.
Step 6: shaping 1: four heads that rise of replacement, the External Shape phase of described four rise a shapes and detail drawing requirement
Seemingly, bulging among round steel pipe is partially placed into special die, pulls four heads that rise to make in round steel pipe shape and mold with hydraulic cylinder
Chamber is adjacent to, and reaches drawing requirement size.
Step 7: shaping 2: several cubic thickness iron blocks are put into round steel pipe bulging part interior, with press machine to steel
Pipe bulging part carries out compacting shaping, so that bulging part top and bottom are smooth, parallel.
Step 8: finishing: being processed to the round hole of bulging position top and bottom, make standard circular, simultaneously
Thread Pilot hole, tapping female bore are bored by drawing in circular, and tube head is finished.
Technical effect and advantage of the invention: avoiding that casting manufacturing process is more complicated, and the process-cycle is long, yield rate
It is low, and the steel of steel plate weldment weld are more crisp after high-temperature soldering, the phenomenon that problem is easy to appear in use, rear wall
Pipe overall processing is at finished product, and simple process, product intensity is high, long service life.

Specific embodiment
With reference to the attached drawing in the embodiment of the present invention, the embodiment of the present invention is described in detail.
In attached drawing, heavy wall round steel pipe 1 presses the blanking of technique desired size, and carries out the draw to technique to tube head on machine for shrinking
Then desired size processes rectangular opening 2 by technique desired size, heavy wall round steel pipe middle section is heated to 800 degree, with pressure
Steel pricker 3 is pressed into rectangular opening middle position by power machine, and steel pricker de-pegs downward through rectangular opening, and four are risen and first 4 is put into
In the round hole that steel pricker 3 expands, hydraulic cylinder push rod 6, which is fixed on, to rise on a pull rod 5, and hydraulic cylinder 8 is fixed on hydraulic cylinder fixed plate 7
On, start four hydraulic cylinders, four rise and first 4 while being pulled outwardly dynamic, force heavy wall round steel pipe 1 to be deformed into approximate circle, rise head
It is replaced with shaping and rises first 9 and 10, steel pipe bulging is partially placed into shaping mould 11, restarting hydraulic cylinder pulling rises first 9, by force
It makes approximate circle steel pipe to continue to be deformed into cavity-like in mold 11, unloads the head that rises, be put into iron block in round steel pipe bulging partial lumen
12, as support, carry out compacting shaping to round steel pipe bulging part with press machine, so that bulging part top and bottom are smooth, parallel,
The round hole of bulging position top and bottom is processed, makes standard circular, while boring by drawing in circular
Thread Pilot hole, tapping female bore, finish tube head, complete finished product.
