A kind of structure of typical decile rectangular end face tooth forging 100.The forging 100 of decile rectangular end face tooth include axle portion 101 and
Positioned at the head 102 of the one end of axle portion 101, the upper surface on the head 102 is recessed to form head chamber 103, the head chamber 103
Last week is provided with some rectangular end face teeth 104 equidistantly arranged at.
Very high, prior art is required to the equal indicative of rectangular end face tooth 104 with decile rectangular end face tooth forging 100
In, the general method being combined using warm forging extrusion process completes the shaping with decile rectangular end face tooth forging 100, i.e.,：Temperature
Forging extruding obtains the forging stock with the profile of head chamber 103, then last week edge at milling of the practical Digit Control Machine Tool in the head chamber of forging stock
Go out rectangular end face tooth 104.
The shaping efficiency of process for machining is low, and produces a large amount of waste materials, extends the production cycle of product, improves production
The production cost of product.Therefore, it is necessary to the production technology of the existing forging with decile rectangular end face tooth is improved.
The content of the invention
In order to solve the above-mentioned technical problem, the invention provides a kind of shaping work with decile rectangular end face tooth forging
Skill, its concrete technical scheme are as follows：
A kind of moulding process of the forging with decile rectangular end face tooth, it in turn includes the following steps：
Blanking：Obtain bar-shaped forging stock；
Jumping-up：Bar-shaped forging stock is inserted in the die cavity of heading die, jumping-up is carried out to forging stock, obtains one end formed with thicker
Head forging stock；
It is anti-to squeeze：Forging stock after jumping-up is inserted in the die cavity of anti-extruding mold, it is counter to forging stock to be squeezed so that the head of forging stock
Form the head cavity of indent；
Just squeeze：Forging stock after anti-squeeze is inserted in the die cavity of positive extruding mold, forging stock is carried out just to squeeze so that the head of forging stock
Upper surface formation of inner chamber etc. divides rectangular end face tooth.
Further, after the anti-crowded step, the step of just squeezing also includes face work step, the car before
End face step is used to carry out turning to the upper end on the head of the forging stock after anti-squeeze so that the upper edge of head cavity forms flat
Whole upper surface.
Further, also include having the following steps after the blanking step, before the jumping-up：
Ball blast cleans：Ball blast cleaning is carried out to the surface of forging stock using Shotblast cleaning machine, to remove the oxide skin on its surface,
So as to increase the surface area of forging stock；
Coating：Coating treatment is carried out to the surface of forging stock, makes one layer of graphite of its surface uniform fold；
Annealing：Forging stock is made annealing treatment using annealing furnace, to remove its internal stress.
Further, after the jumping-up step, also comprise the following steps before the anti-crowded step：
Normalizing：Normalized treatment is carried out to forging using normalizing furnace, to lift the toughness of forging stock.
Further, after the face work step, also comprise the following steps before the anti-crowded step：
Ball blast cleans：Ball blast cleaning is carried out to the surface of forging stock using Shotblast cleaning machine, to remove the oxide skin on its surface,
So as to increase the surface area of forging stock.
Compared with prior art, the moulding process of the forging proposed by the present invention with decile rectangular end face tooth, it is used
End-tooth mould completion etc. divides the extrusion forming of rectangular end face tooth, so as to shorten the forging for carrying decile rectangular end face tooth
Production cycle, reduce the production cost of product.
Brief description of the drawings

Fig. 2 is Fig. 1 top view；
Fig. 3 is the forming process figure of the forging with decile rectangular end face tooth of the present invention.
Embodiment
To make the above objects, features and advantages of the present invention, can be more obvious understandable, it is below in conjunction with the accompanying drawings and specific real
Applying mode, the present invention is further detailed explanation.
" one embodiment " or " embodiment " referred to herein refers to may be included at least one implementation of the present invention
Special characteristic, structure or characteristic." in one embodiment " that different places occur in this manual not refers both to same
Individual embodiment, nor the single or selective embodiment mutually exclusive with other embodiment.
As shown in figure 3, in a specific embodiment, the forging provided by the invention with decile rectangular end face tooth into
Type technique comprises the technical steps that：
1st, blanking：Bar-shaped forging stock is obtained, as shown in Fig. 3 (a)；
