The powder metallurgy molding die for a planet carrier base plate is mainly used to mold a planet carrier base plate in a powder metallurgy process.
Description
Technical field
A kind of planet carrier base plate of the utility model powder metallurgy forming mould belongs to the forming die for powder metallurgy technical field.
Background technology
What traditional planet carrier base plate used is cast member and forge piece, the general casting that adopts obtains blank, the interior tissue of foundry goods is inhomogeneous, coarse grains, service life is short, can produce casting flaw during casting, the intensity, process quality and the serviceability that affect planet carrier are unstable, the planet carrier base plate performance of Forging Technology preparation increases than cast member, but machining efficient is low, and the cost height can not be used for producing in enormous quantities.
The utility model content
The utility model overcomes the deficiency that prior art exists, technical problem to be solved has provided a kind of simple in structure, need not machining, the planet carrier base plate powder metallurgy forming mould of good product quality after the moulding after the moulding.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of planet carrier base plate powder metallurgy forming mould, comprise: upper punch and undershoot, the below of described upper punch is provided with undershoot, described upper punch comprises a upper punch and two upper punches, the inside of a described upper punch is equipped with two upper punches, described undershoot comprises shaping female mold, one undershoot, two undershoots, three undershoots and plug, the below of a described upper punch is provided with shaping female mold, one undershoot, two undershoots, three undershoots and plug, a described undershoot, two undershoots, three undershoots are arranged between shaping female mold and the plug, a described upper punch, two upper punches, shaping female mold, one undershoot, two undershoots, three undershoots and plug are matched in clearance between any two.
Be provided with external splines on the periphery of described two upper punches.
Be provided with boss and annular groove on the described upper punch end face.
The beneficial effect that the utility model compared with prior art has is: the utility model adopts powder metallurgy special C-shaped mould bases, the release method of pulling-down type, can one-shot forming with the planet carrier base plate of interior step, spline and boss, omitted original machining operation, effectively reduce simultaneously manufacturing cost, enhance productivity, saved material.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the outside drawing of mould in the utility model.
Fig. 2 is the cutaway view of mould in the utility model.
Among the figure: 1 is upper punch, and 2 is undershoot, and 3 is a upper punch, and 4 is two upper punches, and 5 is shaping female mold, and 6 is a undershoot, and 7 is two undershoots, and 8 is three undershoots, and 9 is plug.
The specific embodiment
Such as Fig. 1, shown in Figure 2, a kind of planet carrier base plate powder metallurgy forming mould, comprise: upper punch 1 and undershoot 2, the below of described upper punch 1 is provided with undershoot 2, described upper punch 1 comprises a upper punch 3 and two upper punches 4, the inside of a described upper punch 3 is equipped with two upper punches 4, described undershoot 2 comprises shaping female mold 5, one undershoot 6, two undershoots 7, three undershoots 8 and plug 9, the below of a described undershoot 3 is provided with shaping female mold 5, one undershoot 6, two undershoots 7, three undershoots 8 and plug 9, a described undershoot 6, two undershoots 7, three undershoots 8 are arranged between shaping female mold 5 and the plug 9, a described upper punch 3, two upper punches 4, shaping female mold 5, one undershoot 6, two undershoots 7, three undershoots 8 and plug 9 are matched in clearance between any two.
Be provided with external splines on the periphery of described two upper punches 4.
Be provided with boss and annular groove on a described upper punch 3 end faces.
The utility model powder metallurgy forming mould is installed on the C pattern frame.
The course of work of the present utility model is: when specifically using, a kind of planet carrier base plate of the utility model powder metallurgy forming die molding process is divided into powder filling, compacting, three rank of the demoulding.When powder is filled, carry out powder filling according to compression ratio, the powder feeding footwear are shaken 3-5 time on die cavity top according to default program, to guarantee closely knit being filled with in the die cavity of powder.During compacting, after the operation program of press started, a upper punch 3 moved down, and two upper punches 4 contact with plug 9 and float downwards, when a upper punch 3 contacts the beginning compressing powder with powder, moved down powder pressing forming after a undershoot 6 and two undershoots 7 are under pressure.During the demoulding, shaping female mold 5 is left behind, and adopts the mode of the protection demoulding, and upper punch 1 contacts with the section of part all the time, prevents because elastic after effect causes latent crack occurring in the position that part section changes.After moulding former 5, a undershoot 6, two undershoots 7 were deviate from fully, upper punch 1 was return, and plug 9 is left behind, and finishes the demoulding.Can utilize the powder metallurgical technique one-shot forming to go out such planet carrier base plate according to the compacting tool set design that the utility model adopts, through checking and checking, can substitute the technique of machining fully and can satisfy instructions for use.
The above has done detailed description to embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-described embodiment, in the ken that those of ordinary skills possess, can also under the prerequisite that does not break away from the utility model aim, make various variations.
