Abstract
The utility model discloses an overlength semi -axle flange section forming die, it includes upper connecting plate, goes up the mould buckle, goes up mould, lower bolster and lower mould, and upper connecting plate installs activity cylinder bottom face on the hydraulic press, goes up the mould buckle and goes up the mould dress bottom upper connecting plate, and the lower bolster is adorned on the table surface of hydraulic press, and the lower mould is installed in the lower bolster. The utility model discloses in the bar pressure reverse mould utensil die cavity with the heating, ring flange section blank has been formed. The intact back of shaping, the lower mould is automatic to be opened, takes out the blank. After the ring flange section turning of this mould processing, the semi -axis that forms after adopting friction weld is through to the test of components of a whole that can function independently friction weld semi -axis, quiet turn round intensity and twist reverse fatigue strength all conform with technical requirement.
Description
Technical field
This utility model belongs to machinery industry component structural and processing technique field, is related to a kind of automobile axle shaft structure and adds
Work technology is and in particular to a kind of overlength semiaxis flange sections mould.
Background technology
Automobile Design structure is more and more compacter, and function is more and more perfect, and some drive some strength members on forward and backward bridge
Structure becomes increasingly complex, such as car rear axle semi-axis, and because vehicle is continually changing, some half shaft length are more and more longer, connects wheel hub
Ring flange increasing.With half front axle flange typically all in below Φ 160mm, but the birth with SUV automobile, this half method of principal axes
Blue disk diameter is just increasing.Some semiaxis ring flange diameters have reached Φ 180mm, and length is also up to 1 meter.
It is known that semiaxis is a kind of longaxones parts, one is connected with main gearbox assembly in the form of spline, another
Head is connected with form of flanges with hub for vehicle wheel, is the tie of transmission power.Whole in the past semiaxis is all integral type, and centre does not have
It is partitioned from, its raw material is all using steel bar（Generally Φ 40mm）As original material, spline is processed in one end
Pattern, the other end is then processed into the pattern of ring flange.Semiaxis outside dimension at spline connection typically in Φ 30mm- Φ 38mm,
Once, but ring flange is then by the first heating of one section of bar and then reuse oil pressure or pendulum stone roller technology gathers pressure for bar machining
Become Flange-shaped Parts.
Utility model content
This utility model is in the case that overlength semiaxis is divided into flange sections and two sections of bar section, mainly for ring flange
Section molding, thus provide a kind of overlength semiaxis flange sections mould.
This utility model is realized in：
A kind of overlength semiaxis flange sections mould, it include mould connecting plate, upper die button plate, upper die and lower die plate and
Lower mould, upper mould connecting plate is arranged on the upper activity cylinder bottom face of hydraulic press, and upper die button plate and upper mould are contained in mould connecting plate bottom, under
Template is contained on the work top of hydraulic press, and lower mould is arranged in lower template.
Further, described lower mould is divided into symmetrical two piece, and one piece is fixed on and is locked in lower template, and another piece is connected to oil
On the movable cylinder that compressor operation table top is provided with.
Further, the movable cylinder that the upper activity cylinder of described hydraulic press is provided with hydraulic press operating platform face is by signal even
Connect.
Further, design a locating rod at the endoporus of described lower mould lower end.
This utility model overwhelms the bar of heating in mold cavity, defines flange sections blank.After molding is complete, lower mould
Automatically open up, take out blank.After the flange sections turning of this mould processing, the semiaxis being formed after using friction welding is by right
Split friction welding semiaxis is tested, and quiet torsion intensity and torsional fatigue strength are all in accordance with technical requirements.

Specific embodiment
This utility model passes through the following examples and can make progressive description to this utility model, however, this practicality
New scope is not limited to following embodiments.
Embodiment 1：Referring to the drawings：
The flange plate forming die of overlength semiaxis includes mould connecting plate 1, upper die button plate 2, upper mould 3, lower template 4, lower mould
5, wherein descend mould 5 to be split type.When producing flange sections, carry out according to the following steps：
The first step：Die-filling.By upper mould connecting plate 1 be arranged on hydraulic press upper activity cylinder above, go up simultaneously die button plate 2 and on
Mould 3 is contained on mould connecting plate 1, so also just keeps up with movable cylinder and connects together, then lower template 4 is contained on work top,
Lower mould 5 is divided into two pieces, and one piece is fixed on and is locked in lower template 4, and another piece is connected on the movable cylinder of equipment.Lower mould
A locating rod 6 is designed at the endoporus of 5 lower ends.
Second step：Heating.The bar heating one end that flange sections 100 are used is to the state being easy to molding.
3rd step：Molding.Bar tong of heating is clamped in the die cavity of lower mould 5, opens oil pressure unit, lower mould
Automatic die assembly, upper mould 3 at the uniform velocity moves downward with upper cylinder, gradually overwhelms the bar of heating in mold cavity, defines method
The blank of blue disk section.After molding is complete, lower mould automatically opens up, and takes out blank.
4th step：Turning.The blank of molding is processed into, with method for turning, the flange sections 100 designing.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all this
Any modification, equivalent and improvement made within the spirit of utility model and principle etc., should be included in this utility model
Protection domain within.
