Enter to fill hole axle in hole to coordinate；The conical surface collectively forms tail portion chamfering slot with casement.
Preferably, casement further includes insertion section and pedestal, and insertion section is step surface with pedestal interface, and top surface setting exists
On the top of insertion section, insertion section is inserted into filling hole.
Preferably, step surface is provided with escape.
Preferably, top surface constitutes recess portion with placement hole.
Preferably, the angular range of the conical surface and through-hole central axis is more than 0 ° and is less than 90 °.
Preferably, the conical surface extends in the range of casement insertion.
Preferably, top surface is provided with chamfering, and the conical surface collectively forms tail portion chamfering slot with chamfering.
Preferably, through-hole head and the tail both ends are respectively arranged with guide section.
Advantageous effect is：
Compared with prior art, a kind of good cold headers of processing quality of the utility model are by using a kind of knockdown
Mode is punched, is assembled to form by split type mode body and casement hole axle, is provided with placement hole on mode body, workpiece is placed
It is withstood in placement hole and by the top surface of casement so that product mounting is safe, and the conical surface is provided on the inside of the through-hole on mode body, leads to
It crosses the conical surface and casement and collectively forms tail portion chamfering slot in an axial direction so that riveting nut blank is vertically during cold-heading
Tail portion chamfering slot axial deformation occurs rather than radial direction so that riveting nut is not easy deviation in radial dimension, and finally so that cold
Upsetting machine good product quality.
Description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing, wherein：
Fig. 1 is a kind of part-structure schematic diagram of the good cold headers of processing quality of the utility model；
Fig. 2 is the assembling schematic diagram that component punches mode；
Fig. 3 is the structural schematic diagram of part mode body；
Fig. 4 is the structural schematic diagram of part casement.
Specific implementation mode
A kind of cold headers that processing quality is good punch mould as shown in Figure 1, including body 1, punching mode 2 and rushing stick 4
Benevolence 2 is detachably mounted to the punching station of body 1, and workpiece 3 is placed on punching mode 2, rushes stick 4 and 2 center of punching mode
Axis overlaps, and rushes stick 4 and punching mode 2 moves toward one another, be punched out to workpiece 3 by the stick 4 that rushes on body 1.Such as Fig. 2, Fig. 3 and
Shown in Fig. 4, punching mode 2 includes mode body 21 and casement 22.Mode body 21 is provided with through-hole 211, and casement 22 is arranged useful
In the punching 221 for rushing the impact of stick 4.Through-hole 211 includes one section of filling 212, one sections of hole placement hole 213 and the conical surface 215.Placement
It is connected by the conical surface 215 between hole 213 and filling hole 212.Placement hole 213 is for accommodating workpiece 3 so that workpiece 3 will not when work
Run out of the fixed range of punching mode 2.Wherein one end is provided with top surface 225 in the both ends of casement 22, and filling hole is inserted into this one end
Hole axle cooperation both in 212.The distance that casement 22 is inserted into should be proper can just touch the conical surface 215, that is, bores
Face 215 extends in the range of the insertion of casement 22.At this point, the conical surface 215 collectively forms tail portion chamfering slot 24 with casement 22.Tail
Portion's chamfering slot 24 extends along the direction of punching.Certainly, chamfering 228 is also provided on top surface 225, and by the conical surface 215 and chamfering
228 collectively form tail portion chamfering slot 24.So that during cold-heading workpiece 3 along tail portion chamfering slot 24 occur axial deformation rather than
It is radial so that workpiece 3 is not easy deviation in radial dimension, radial dimension is required for high workpiece, the production of cold headers production
Quality is more preferable.
Preferable embodiment, as shown in Figure 2 and Figure 4, casement 22 are in step-like, are provided with insertion section 223 and pedestal
224, the interface of insertion section 223 and pedestal 224 is step surface 226, and top surface 225 is arranged on 223 top of insertion section, insertion section
223 are inserted into filling hole 212, until step surface 224 is bonded with the bottom face of mode body 21 so that casement 22 is tight with mode body 21
Close fit, when punching, will not loosen.In addition the holds out against screw (not marked in figure) of fastening can be set on the side wall of casement 22,
So that casement 22 is connected firmly with mode body 21, and can easily dismantle when needed.
Preferable embodiment, as shown in figure 4, step surface 226 is provided with escape 227, step surface 224 and mode body 21
Bottom face fitting when will not be processed by nose angle be influenced so that so that casement 22 and mode body 21 are fitted close.
Preferable embodiment, as shown in Fig. 2, top surface 225 is used as bottom surface, placement hole 213 to limit common structure as surrounding
At recess portion 23, recess portion 23 is for placing workpiece 3 so that workpiece 3 will not run out of the fixed range of punching mode 2 when processing.
The angular range of preferable embodiment, the conical surface 215 and 211 central axis of through-hole is more than 0 ° and is less than 90 °, guarantee
The tail portion chamfering slot 24 of formation is the axial direction along through-hole 211 so that workpiece 3 is radial free according to preset axial deformation
Deformation so that good product quality.
Preferable embodiment facilitates workpiece 3 as shown in figure 3,211 head and the tail both ends of through-hole are respectively arranged with guide section 214
With being put into for casement 22.
Above example is only to illustrate the technical solution of the utility model and is not intended to limit it, all without departing from this
Any modification of utility model spirit and scope or equivalent replacement should all cover the range in technical solutions of the utility model
It is interior.
