Description
Technical field
The utility model belongs to technical field of mechanical processing, concretely relates to a kind of cold-heading mandril.
Background technology
In rivet, slender bolt process, cold-heading mandril is needed to withstand on after processing part, due to rivet, bolt
Larger impact force is generated when head shape trimming is processed, cold-heading mandril is made to be also subjected to prodigious impact force.Existing cold-heading top
Bar is smaller when rivet, the diameter of bolt, and the diameter of cold-heading mandril is accordingly also smaller, therefore intensity is weaker, rivet, bolt head trimming
When be easy to fracture mandril, cause mandril to scrap.Mandril also more wasteful time is replaced, production efficiency is reduced, when serious
It will cause product rejection.

It is equipped with the first pilot hole with the top splenium clearance fit, the thimble is set in the pilot hole, and the top splenium is supported
Tightly in the thimble end, described thimble the other end enters the guide sleeve after passing through pedestal.
Preferred embodiment on the basis of said program and as said program：The guide sleeve is provided between the thimble
Second pilot hole of gap cooperation.
Preferred embodiment on the basis of said program and as said program：The top splenium is provided with connecting plate, institute
It states connecting plate top splenium is connected with the tube wall of casing, the guide part is provided with guide groove corresponding with the connecting plate.
Preferred embodiment on the basis of said program and as said program：The connecting plate is arranged symmetrically.
Preferred embodiment on the basis of said program and as said program：Thimble is arranged with the top splenium contact jaw
There are guide head, the guide head and the guide groove clearance fit.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：Shaping mould die holder, casing and guide sleeve
Setting, shaping mould die holder is provided with guide part, pilot hole is provided in guide part, and mandril is located in pilot hole, guide sleeve be arranged and
Guide part makes guide part and mandril intensity increase, improves the durability of mandril.

Specific implementation mode
To keep the purpose, technical scheme and advantage of the application clearer, below in conjunction with the attached drawing in embodiment, to reality
The technical solution applied in example is clearly and completely described, it is clear that described embodiment is only that the application part is implemented
Example, rather than whole embodiments.Based on the embodiment provided, those of ordinary skill in the art are not before making creative work
The every other embodiment obtained is put, shall fall in the protection scope of this application.
In the description of the present application, it is to be understood that the orientation or positional relationship of the instructions such as term "upper", "lower" is base
In orientation or positional relationship shown in the drawings, it is merely for convenience of description the application and simplifies to describe, rather than indicate or imply
Signified device or element must have a particular orientation, with specific azimuth configuration and operation, therefore should not be understood as to this
The limitation of application.
In the description of the present application, term " first ", " second " etc. are used for description purposes only, and should not be understood as instruction or
It implies relative importance or implicitly indicates the quantity of indicated technical characteristic.
Embodiment one
A kind of cold-heading mandril, including shaping mould die holder 10, casing 20, thimble 40 and guide sleeve 30, the shaping mould die holder 10
It being made of pedestal 11 and guide part 50, described sleeve pipe 20 is sheathed on the guide part 50, and described sleeve pipe 20 is provided with top splenium 23,
The guide part 50 is provided with the pilot hole 53 with 23 clearance fit of the top splenium, and the thimble 40 is set to the pilot hole
In 53, the top splenium 23 is pushed against 40 end of the thimble, and 40 the other end of the thimble enters described after pedestal 11
Guide sleeve 30.
The guide sleeve 30 is provided with the pilot hole 31 with 40 clearance fit of the thimble.
Since thimble 40 intensity is high, while its brittleness also can be larger, and the first pilot hole 53 and the second pilot hole 31 are set
It sets and provides support well for 40 circumferential surface of thimble, preventing from occuring bending and deformation when thimble 40 receives impact forces causes
It is broken.
The top splenium 23 is provided with connecting plate 21, and top splenium 23 is connected by the connecting plate 21 with the tube wall 22 of casing 20
It connects, the guide part 50 is provided with guide groove corresponding with the connecting plate 21 54.
Thimble 40 is provided with guide head 41 with 21 contact jaw of the top splenium, between the guide head 41 and the guide groove 54
Gap coordinates.
Preferably, seeing Fig. 4-6, connecting plate 21 is to be symmetricly set on 23 both sides of top splenium, forms "-" type structure, that
Guide groove 54 and guide head 41 are also "-" type structure accordingly, and such structure setting makes 23 intensity of top splenium increase
Adding, guide groove 54 and the setting of guide head 41 prevent casing 20 and thimble 40 from rotating during the motion, generate torsional moment,
Since the intensity of thimble 40 is high, while its brittleness is also larger, and torsional moment can be easy to make its torsional fracture.
Embodiment two
It is with the distinctive points of embodiment one, sees Fig. 7-9,23 side of top splenium is symmetrically set to centered on connecting plate 21
Form star（It is attached to be not shown in figure）Or decussate texture, then guide groove 54 and guide head 41 are also star or ten accordingly
Character form structure；
Preferably, connecting plate 21（See Fig. 7）, guide groove 54（See Fig. 8）, guide head 41（See Fig. 9）For decussate texture.
Certainly, connecting plate 21, guide groove 54, guide head 41 can also be the knot that guiding and support can be provided for thimble 40
Structure.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
It encloses, therefore：The equivalence changes that all structures, shape, principle according to the utility model are done, should all be covered by the protection of the utility model
Within the scope of.
