Abstract
Guide sleeve structure, including guide sleeve body are rushed in a kind of forming of powder metallurgy gear hub class, it is characterised in that: are axially formed in the guide sleeve body and rushed the inner cavity that size matches on, the boss to match with upper jet-bedding mouth is formed on inner cavity.Guide sleeve has the inner cavity with upper punching cooperation, forms the boss to match with upper jet-bedding mouth on inner cavity, in this way by the cooperation of guide sleeve, makes to rush outer diameter and is supported, the deformation and fracture of formed punch when reducing compression.The utility model is simple and reasonable, good forming effect, solves the problems, such as tooth hub formed punch deformation and fracture in forming, while increasing the service life of the part mould structure.
Description
Technical field
The utility model belongs to powder metallurgically manufacturing technical field, is related to a kind of mold more particularly to a kind of powder metallurgy
Guide sleeve structure is rushed in the forming of tooth hub class.
Background technique
Powder metallurgy is to use metal or use metal powder as raw material, manufacture metal material, compound by shaping and being sintered
And the technology of various types product, it is widely used in every field, since powder metallurgy has unique chemical group
At with mechanical, physical property, be that traditional casting method can not obtain, can be used for manufacturing automobile, motorcycle, textile machine,
The various powdered metal parts such as electric tool, hardware tool, electric appliance.
Shaping dies be sintered metal product production during key equipment, iron powder used in metallurgy depended on pressure at
It is shaped in shape mold, the size of drip molding is the guarantee of finished parts size.Therefore, in the process of tooth hub class part, at
Shape formed punch is the important tool for guaranteeing product accuracy.
In conventional powder metallurgy gear hub forming punch design, forming punch is thin-walled and discontinuous, then pressing
During system, formed punch is easily deformed and is broken.Formed punch, which will not do how much quantity, to be scrapped, and the waste of mold is caused, while
Reduce working efficiency.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of structure for the above-mentioned state of the art and simply close
Guide sleeve structure is rushed in the good powder metallurgy gear hub class forming of reason, forming effect, deforms and breaks to solve tooth hub formed punch in forming
It splits, leads to the problem that die life is short.
Technical solution adopted by the utility model to solve the above technical problems is as follows: in a kind of powder metallurgy gear hub class forming
Rush guide sleeve structure, including guide sleeve body, it is characterised in that: axially form in the guide sleeve body and rush what size matched on
Inner cavity forms the boss to match with upper jet-bedding mouth on inner cavity.
As an improvement, the boss is circumferentially equi-spaced three corresponding with upper jet-bedding mouth.
As an improvement, the fit clearance that the width of the boss rushes width of rebate on is 0.015~0.025mm.
Further, it is 0.02~0.03mm that the intracavity diameter of the guide sleeve body rushes the fit clearance of tooth top diameter on.
Finally, the outer end of the guide sleeve body forms expanding ring-shaped step, guide sleeve body is set in by pressure ring
Ring-shaped step on fixed with rush-up seat.
Compared with the prior art, the advantages of the utility model are: guide sleeve has the inner cavity with upper punching cooperation, on inner cavity at
Type has the boss to match with upper jet-bedding mouth, in this way by the cooperation of guide sleeve, makes to rush outer diameter and is supported, reduces compression
The deformation and fracture of Shi Chongtou.The utility model is simple and reasonable, easily manufactured, good forming effect, solve tooth hub at
The problem of formed punch is deformed and is broken when shape, while increasing the service life of the part mould structure.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the guide sleeve of the utility model embodiment；
Fig. 2 is the side view of Fig. 1；
Fig. 3 is the structural schematic diagram of the upper punching of the utility model embodiment；
Fig. 4 is the side view of Fig. 3；
Fig. 5 is the assembling schematic diagram of the shaping dies of the utility model embodiment.
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
As shown in Fig. 1~5, guide sleeve structure, including guide sleeve body 1, guide sleeve sheet are rushed in a kind of forming of powder metallurgy gear hub class
Axially formed on body 1 with the inner cavity 11 that matches of 2 sizes of upper punching, form on inner cavity 11 match with upper jet-bedding mouth 21 it is convex
Platform 12, boss 12 are corresponding with upper jet-bedding mouth 21 circumferentially equi-spaced three, the width of boss 12 and upper jet-bedding mouth
The fit clearance of 21 width L2 is 0.015~0.025mm, 1 tooth top diameter D2's of the 11 diameter D1 of inner cavity of guide sleeve body 1 and upper punching
Fit clearance is 0.02~0.03mm, and the outer end of guide sleeve body 1 forms expanding ring-shaped step 13, is arranged by pressure ring 3
It is fixed on the ring-shaped step 13 of guide sleeve body 1 by bolt and rush-up seat.
In this way, passing through the cooperation of guide sleeve body 1, the effect of positioning and guiding is not only acted as, is also propped up 2 outer diameters of punching
Support, the deformation and fracture of formed punch when reducing compression.
The utility model is good and easily manufactured through implementing using effect, preferably solves and rushes change on tooth hub class product
The problem of shape and fracture.After the punch structure of the present embodiment, formed product size can reach requirement, also improve formed punch
Service life.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
