Description
Technical field
The combined type punching mould that the utility model is related to be used on a kind of cold headers more particularly to cold headers.
Background technology
Cold headers are through cold forging by fastener wire to reach a kind of equipment of the shape and size of semi-finished product.Cold-heading
It is generally equipped with punching on machine and touches benevolence, effect is to fix riveting nut embryo material, facilitates and plays riveting nut embryo material punching when equipment cold-heading
It wears.Punching mould in the prior art is monoblock type punching mould, in punching since riveting nut tail portion periphery is not affected by mold limit
System is squeezed to easy to produce radial deformation and swell and causes tail portion bar diameter super poor, influences product quality in punching.
Utility model content
The utility model aims to solve the problem that above-mentioned mentioned technical problem, provides a kind of products radial and deforms small combined type
Punch mould.
The utility model is realized through the following technical scheme：
A kind of combined type punching mould, including mode body and casement；Mode body is provided with through-hole, and casement is provided with punching；
Through-hole includes one section of filling hole, one section of placement hole and the conical surface, is connected by the conical surface between placement hole and filling hole；It is set in casement
Hole axle cooperation in filling hole is inserted into the one end for being equipped with top surface；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, the utility model is led to by using knockdown separate structure by mode body and casement
Hole axle assembly is crossed, placement hole is provided on mode body, workpiece can be placed in placement hole and be withstood by the top surface of casement, made
Product mounting is safe, the conical surface is provided on the inside of through-hole on mode body, is collectively formed in an axial direction by the conical surface and casement
Tail portion chamfering slot so that during cold-heading the tail portion chamfering slot of riveting nut blank vertically axial deformation occurs rather than
It is radial so that riveting nut is not easy deviation in radial dimension, and finally so that cold headers 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 combined type punching mode assembling structure schematic diagram；
Fig. 2 is the combined type punching mode structure schematic diagram of the utility model；
Fig. 3 is the structural schematic diagram of part mode body；
Fig. 4 is the structural schematic diagram of part casement.
Specific implementation mode
As shown in Figure 1, a kind of combined type punching mould, including mode body 1 and casement 2, it is detachably mounted to cold headers
Punching station, workpiece 3 is placed on combined type punching mould, rushes stick and overlapped with the central axis of combined type punching mould, the two phase
To movement, workpiece 3 is punched out by the stick that rushes on cold headers.As shown in Figure 2, Figure 3 and Figure 4, mode body 1 is provided with through-hole
11, casement 2 is provided with punching 21.Punching 21 is used for by rushing stick.Through-hole 11 include one section filling 12, one sections of hole placement hole 13 with
And the conical surface 15.It is connected by the conical surface 15 between placement hole 13 and filling hole 12.When placement hole 13 makes work for accommodating workpiece 3
Workpiece 3 will not run out of the fixed range of punching mould.Wherein one end is provided with top surface 25 in the both ends of casement 2, this one end is inserted into and is filled out
Fill the two hole axle cooperation in hole 12.The distance that casement 2 is inserted into should be proper can just touch the conical surface 15, that is, bores
Face 15 extends in the range of the insertion of casement 2.At this point, the conical surface 15 collectively forms tail portion chamfering slot 4 with casement 2.It falls tail portion
Chamfered groove 4 extends along the direction of punching.Certainly, chamfering 28 is also provided on top surface 25, and by the conical surface 15 and 28 common structure of chamfering
At tail portion chamfering slot 4.So that along tail portion chamfering slot 4 axial deformation occurs for workpiece 3 rather than radial direction during cold-heading so that work
Part 3 is not easy deviation in radial dimension, radial dimension is required for high workpiece 3, and the product quality of cold headers production is more preferable.
Preferable embodiment, as shown in Figure 2 and Figure 4, casement 2 are in step-like, are provided with insertion section 23 and pedestal 24,
The interface of insertion section 23 and pedestal 24 is step surface 26, and top surface 25 is arranged on 23 top of insertion section, and insertion section 23 is inserted into and is filled out
It fills in hole 12, until step surface 24 be bonded with the bottom face of mode body 1 so that casement 2 and the tight fit of mode body 1, when punching
It 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 2 so that casement 2 and mould
Benevolence body 1 is connected firmly, and can easily dismantle when needed.
Preferable embodiment, as shown in figure 4, step surface 26 is provided with escape 27, the bottom of step surface 24 and mode body 1
End face will not be processed by nose angle when being bonded be influenced so that so that casement 2 and mode body 1 are fitted close.
Preferable embodiment, as shown in Fig. 2, top surface 25 is used as bottom surface, placement hole 13 to be collectively formed as surrounding limitation
Recess portion 5, recess portion 5 is for placing workpiece 3 so that workpiece 3 will not run out of the fixed range of punching mould when processing.
The angular range of preferable embodiment, the conical surface 15 and 11 central axis of through-hole is more than 0 ° and is less than 90 °, guarantee shape
At tail portion chamfering slot 4 be axial direction along through-hole 11 so that workpiece 3 is according to preset axial deformation rather than radial freely becomes
Shape so that good product quality.
Preferable embodiment facilitates 3 He of workpiece as shown in figure 3,11 head and the tail both ends of through-hole are respectively arranged with guide section 14
Casement 2 is put into.
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.
