Abstract
The utility model belongs to a kind of tubaeform product mold of hard alloy；Undershoot including being located at mold bottom, the middle part of undershoot is provided with projection, the both sides of undershoot are provided with concave station, the projection is provided with tubaeform product, and the concave station is provided with die sleeve, and the inner side of die sleeve, which is provided with first, to be rushed, the inside rushed on first is provided with second and rushed, the middle part rushed on second is coated with core bar, and the middle part of core bar through tubaeform product is communicated with the bottom of undershoot, and snap ring is provided between being rushed on the die sleeve and first；With reasonable in design, can not only solve the problems, such as tubaeform formed product layered crackle, and horn mouth circular conical surface pressed density can also be improved, so as to realize one-shot forming, the advantages of greatly shortening the raising operating efficiency of production cycle.
Description
Technical field
The utility model belongs to sintered-carbide die technical field, and in particular to a kind of tubaeform product mould of hard alloy
Tool.
Background technology
All the time, manufacturer typically produces tubaeform product by the way of repaired biscuit, i.e., is first pressed into big cylinder, then
Carry out machine adds repaired biscuit, and such mode easily produces hierarchical crack in tubaeform formed product and produces tailing, production efficiency
It is low, once it is also very high damaged percent defective occur.
Utility model content
The defects of the purpose of this utility model is to overcome in the prior art, and provide it is a kind of reasonable in design, not only can be with
Solve the problems, such as tubaeform formed product layered crackle, and horn mouth circular conical surface pressed density can also be improved, so as to realize
One-shot forming, greatly shorten a kind of tubaeform product mold of hard alloy of production cycle.
What the purpose of this utility model was realized in：Undershoot including being located at mold bottom, the middle part of undershoot is provided with convex
Rise, the both sides of undershoot are provided with concave station, and the projection is provided with tubaeform product, and the concave station is provided with die sleeve, the inner side of die sleeve
Provided with rushing on first, the inside rushed on first is provided with second and rushed, and the middle part rushed on second is coated with core bar, and core bar passes through
The middle part of tubaeform product is communicated with the bottom of undershoot, and snap ring is provided between being rushed on the die sleeve and first.
Preferably, described snap ring is semicircle.
Preferably, the internal diameter of described die sleeve matches with the external diameter rushed on first.
Preferably, the internal diameter rushed on described first matches with the external diameter rushed on second.
The utility model has reasonable in design, can not only solve asking for tubaeform formed product layered crackle
Topic, and horn mouth circular conical surface pressed density can also be improved, so as to realize one-shot forming, greatly shorten the raising work of production cycle
The advantages of making efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to which the technical characteristics of the utility model, purpose and effect are more clearly understood, now control illustrates
Specific embodiment of the present utility model, in the various figures identical label represent identical part.To make simplified form, in each figure
The part related to utility model is only schematically show, they do not represent its practical structures as product.
As shown in figure 1, the utility model is a kind of tubaeform product mold of hard alloy, including it is located under mold bottom
Punching 1, the middle part of undershoot 1 are provided with projection 2, and the both sides of undershoot 1 are provided with concave station 3, and described raised 2 are provided with tubaeform product 4, described
Concave station 3 is provided with die sleeve 5, and the inner side of die sleeve 5, which is provided with first, rushes 6, and the inside of punching 6, which is provided with second, on first rushes 7, on second
The middle part of punching 7 is coated with core bar 8, and the middle part of core bar 8 through tubaeform product 4 communicates with the bottom of undershoot 1, the die sleeve
On 5 and first snap ring 9 is provided between punching 6.Described snap ring 9 is semicircle.Punching 6 on the internal diameter and first of described die sleeve 5
External diameter matches.The internal diameter of punching 6 and the external diameter of punching 7 on second match on described first.
The utility model, which uses, rushes split design, upper punching is divided on first 7 are rushed in punching 6 and second, 7 are rushed on second
Endoporus is furnished with core bar 8, and shaping pressed compact carries centre bore.The internal diameter of die sleeve 5 and the external diameter of punching 6 on first match, and 6 are rushed on first
Internal diameter and on second punching 7 external diameter match, on first rush 6 upper end be provided with annular groove, put two semicircular snap rings 9
It can limit on first that punching 6 is descending, and mold bottom is undershoot 1.
When compressing, two semicircular snap rings 9 will be fixed on die sleeve 5 the utility model in punching 6 on first, and second
Upper punching 7 is first suppressed, and after the compacting of punching 7 extremely and on first rushes 6 sustained heights on second, lays down snap ring 9, while suppress and rushed on second
Size as defined in punching 6 to tubaeform product 4 on 7 and first.
The utility model is using design is rushed in split, when compressing, punching substep pushes in split, solves circular conical surface and circle
Cylinder junction density is excessively good and the problem of causing hierarchical crack.Pressed compact does not need machine to add repaired biscuit, one-shot forming, greatly improves original
The utilization rate and production efficiency of material.
, it is necessary to illustrate in description of the present utility model, unless otherwise clearly defined and limited, term " setting ",
" being provided with " etc. should be interpreted broadly, for example, it may be being fixedly connected, be integrally connected or be detachably connected；Also may be used
To be the connection of two element internals；Can be joined directly together, can also be indirectly connected by intermediary, for this area
For those of ordinary skill, concrete meaning of the above-mentioned term in the utility model can be understood as the case may be.Above
Describe illustrating only for feasibility embodiment of the present utility model in detail, they simultaneously are not used to limit this practicality
New protection domain, all equivalent implementations made without departing from the utility model skill spirit, change and transformation all should wrap
It is contained within the scope of protection of the utility model.
