Description
Technical field
Warm forging technique is the utility model is related to, more particularly to a kind of punch has the warm forging device of guide function.
Background technology
Warm forging refers in recrystallization temperature of steel product or so, improves punch and is molded to obtain the production of Structure of need
Product, in existing structure (as shown in Figure 2), the size of forming cavity is much larger than punch, and punch is fixed on punch and puts on, and punch set is by leading
It is oriented to set, guide sleeve is deposited above lower die between punch and punch set, punch set and guide sleeve, guide sleeve and lower die
In installation gap, the cumulative concentricity caused between punch and forming cavity in gap can not be guaranteed, and influence the reality of product
Warm forging effect.
Utility model content
Shortcoming present in regarding to the issue above, the utility model, which provides a kind of punch, has the warm forging of guide function
Device.
To achieve the above object, warm forging device of a kind of punch of the utility model offer with guide function, including base,
The lower die being concentrically mounted in the base, the lower die is interior to form forming cavity, and punch is located above the forming cavity, its feature
It is：
The punch is divided into pressing part, guide part, connecting portion, the size of the guide part and the forming cavity from the bottom to top
Matching, the connecting portion are fixedly connected with punch set.
As further improvement of the utility model, the lower end of the guide part is machined with chamfering.
The beneficial effects of the utility model are：
Device is additionally arranged guide part on punch, and concentricity during product warm forging improves, and product quality is high.
Brief description of the drawings
Fig. 1 is the warm forging device sectional view that a kind of punch of the utility model has guide function；
Fig. 2 is the sectional view before warm forging punch improves.

Embodiment
As shown in Figure 1, a kind of punch described in the utility model embodiment has the warm forging device of guide function, including bottom
Seat 1, the lower die 2 being concentrically mounted in base 1, lower die 2 is interior to form forming cavity 3, and punch 4 is located at the top of forming cavity 3, its feature exists
In：Punch 4 is divided into pressing part 41, guide part 42, connecting portion 43 from the bottom to top, and guide part 42 is matched with the size of forming cavity 3, even
Socket part 43 is fixedly connected with punch set 5；The lower end of guide part 42 is machined with chamfering.
Device is additionally arranged guide part on punch, and concentricity during product warm forging improves, and product quality is high.
When specifically used, the utility model is understood for convenience, is described with reference to attached drawing；
During work, punch is down moved with punch set, is played and is led between the external peripheral surface of guide part and the endoporus of lower die
To effect, pressing part completes the warm forging of workpiece in forming cavity, due in Warm Forging Process, the external peripheral surface of guide part with
Guiding role is played between the endoporus of lower die, even if making between punch and punch set there are certain inclination in the guiding of lower die
It can also be corrected under, have no effect on the shaping of product, and in original structure, the size of forming cavity is more than punch, punch
It is not directly directed to, but the cylindrical guiding role between the endoporus of guide sleeve covered by punch, punch and punch set, punching
The cumulative precision for causing product in the gap between headgear and guide sleeve, guide sleeve and lower die can not be protected.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the present invention, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on, should be included within the scope of protection of this utility model.
