Description
Technical field
The utility model is related to fastener processing and production industry, especially a kind of double click type cold headers are used with processing uropore
Movable mold.
Background technology
Bolt is common fastener, because its have can self-locking, be simple to manufacture, can be mass-produced, of low cost, tool is mutual
A variety of advantages such as transsexual and the extensive use in multiple fields.It is needed in certain fields using the bolt with uropore, it is so-called
Uropore is exactly opened in the hole on the inside of the bolt far from nut one end.Traditionally due to molding die and technologic limitation, lead
During cause can not operate again while the nut portion of bolt and uropore part are processed, may result in production efficiency in this way
Lowly, the problems such as increased production cost.Therefore need one kind being capable of solution to the problems described above or device now.
Invention content
The utility model is to propose that one kind is simple in structure, design is skilful to solve the above-mentioned deficiency present in the prior art
It is wonderful, it is rationally distributed, it can be in once-through operation, using the impact of two kinds of molds simultaneously by the nut portion of bolt and uropore part
The movable mold processed.
The technical solution of the utility model is：A kind of double click type cold headers processing uropore movable mold, feature
It is：The movable mold includes fixed block 1, and the tail end of mandrel 2 is fixedly plugged in fixed block 1, in 2 outer pivot bush unit of mandrel
There are limited block 3 and active module 4, the end face of the limited block 3 to be contacted with fixed block 1, and in limited block 3 and active module 4
Between be additionally provided with spring 5, the active module 4 is actively socketed in pilot sleeve 6, and the mandrel 2 is actively socketed on out
In the through-hole 7 at 4 axle center of active module, there is forming part 8 in the end set of mandrel 2.
The utility model compared with the existing technology, has the following advantages that：
The double click type cold headers of this kind of structure type processing uropore movable mold, simple in sturcture, ingenious in design, layout
Rationally, it is for being difficult in traditional cold heading technique simultaneously to process nut portion and uropore part in a process
Defect designs a kind of movable mold of special construction, it be internally provided with one can along the active module of impact direction play,
And coordinate with two Secondary Shocks of a diel and two times punch mold, while realizing the processing of nut and uropore, it is one
The processing that two parts can be completed in a process, substantially increases the progress of work, while improving working efficiency, can also drop
Low strap has the processing cost of the bolt of uropore class, and the manufacture craft of this movable mold is simple, and manufacturing cost is cheap, therefore can
To say that it has a variety of advantages, particularly suitable for promoting and applying in the art, market prospects are very wide.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Fig. 2 is motion state schematic diagram of the utility model embodiment under a punching press.
Fig. 3 is motion state schematic diagram of the utility model embodiment under two times punch.
Specific implementation mode
Below in conjunction with description of the drawings specific embodiment of the present utility model.As shown in Figure 1, Figure 2, Figure 3 shows：A kind of double-click
Formula cold headers processing uropore movable mold, it includes a fixed block 1, further includes mandrel 2, the tail end of this mandrel 2 is fixed
It is plugged in fixed block 1, has limited block 3 and active module 4 in 2 outer pivot bush unit of mandrel, opened up at the axle center of active module 4
There are through-hole 7, mandrel 2 to be just actively socketed in this mandrel 2, is additionally provided with forming part 8 in the end of mandrel 2, this forming part 8
There are distance between the end face of active module 4, which is the screw portion of the bolt processed using this movable mold
Length；The end face of above-mentioned limited block 3 is contacted with fixed block 1, and is additionally provided with bullet between limited block 3 and active module 4
Spring 5.
The double click type cold headers of the utility model embodiment are as follows with the course of work of processing uropore movable mold：Metal bar
After material is cut into appropriate length under the action of shear, it is inserted into the through-hole 7 in this movable mold（As shown in Figure 1）,
At this time under the action of spring 5, not in contact with gap width between the two is stroke between limited block 3 and active module 4；
Carrying out one-pass molding（It is preforming）Punching operation when（As shown in Figure 2）, one-time formed ram impacts bar
Expose on the part of active module 4, under the action of impact force, the part of one side bar can be formed with it is one-time formed
The identical shape of punch shape, another aspect active module 4 can also be transported under the action of the impact force towards the direction of limited block 3
It is dynamic, until the other end of active module 4 is contacted with limited block 3, since mandrel 2 is relatively-stationary, it is equivalent to movable mold
Block 4 drives bar thereon towards the direction of mandrel 2, quickly movement, and in the process, the forming part 8 of 2 end of mandrel will be
The tail portion of bar impacts uropore；
After one stroke, when carrying out the punching operation of post forming（As shown in Figure 3）, the punch continuation of post forming
Preforming bar is impacted, by the end impact of bar at required shape, forms nut, and in punch and movable mold
After block 4 detaches, under the action of spring 5, meeting counter motion has processed nut and tail to active module 4 in the process again
The bolt in hole can then be popped up from through-hole 7, complete the processing of a bolt with uropore at this time.
