Limit guarantees the length of the pipe fitting formed after pipe embryo 4 is processed.
Make the support core 22 horizontal sliding as shown in Fig. 2, being equipped between the locating part 23 in auxiliary rod assembly 2 and support core 22
The second dynamic return unit 24, the second return unit 24 include but is not limited to spring, elastic slice and rubber elastomer, are completed the process in pipe fitting
After taking-up, support core 22 slides to original position under the driving of the second return unit 24, waits the processing of next pipe embryo 4.
Further, auxiliary rod assembly 2 further includes guidance set, and guidance set includes shaft shoulder screw 21 and guide rod 25,
The cap head of shaft shoulder screw 21 acts against on the end face of support core 22, and the cylinder of shaft shoulder screw 21 is slidably mounted on support core 22 and locating part
23 inside, the threaded portion of shaft shoulder screw 21 are connected on guide rod 25, and the mounting structure of guide rod 25 is as follows, in upper mold
Guide groove is equipped between 11 and lower die 12, one end of guide groove is connected to card slot, and the other end of guide groove runs through the upper mold
11 and lower die 12, guide rod 25 be slidably mounted in guide groove, guide rod 25 can play guiding role, allow support core in the work of power
It can make straight reciprocating motion under.
Preferably, the cap head diameter of shaft shoulder screw 21 is less than the diameter of support core 22, while again smaller than the diameter of pipe embryo 4,
After processing is completed, the cap head of shaft shoulder screw 21 is located at the inside pipe fitting after processing to pipe fitting in whole or in part, since diameter is less than
The diameter of pipe embryo 4 has gap between the cap head of shaft shoulder screw 21 and the pipe fitting after processing, very easily can be by the pipe of processing
Part is removed.
As shown in fig. 6, the molding die of the present embodiment further includes the second formed punch 32, the second formed punch 32 includes the second jumper bar
321 and what is be mounted in the second jumper bar 321 second rush core 322,32 extruded tube embryo 4 of the second formed punch allows pipe embryo 4 to rush core 322 second
Upper further undergauge, while second rushes core 322 shaft shoulder screw 21 and support core 22 is pushed to make the disengaging pipe embryo 4.Wherein the second punching
The length that core 322 is included in the second undergauge groove formed in the second jumper bar 321 is greater than the undergauge length that pipe embryo 4 finally requires,
The internal diameter of second jumper bar 322 is the final undergauge diameter of pipe embryo 4, and second, which rushes 322 diameter of core, is less than the interior of the pre- final undergauge section of pipe embryo 4
Diameter.
Preferably, clamping assembly 1 further includes cover board 14, as shown in Figure 1, cover board 14 is located at the open-mouth of the slideway,
When pipe fitting is processed, it is ensured that the position after sliding block reset.
Fig. 7, Fig. 8 and Fig. 9 are please referred to, the main process principle of molding die provided in this embodiment is, by 4 sets of pipe embryo
It is connected in support core 22, the right end of pipe embryo 4 comes to locating part, and then the first formed punch acts, and 4 left end of pipe embryo is introduced into the first formed punch
Undergauge groove, when the step surface that first rushes core 312 is encountered in pipe embryo left end, the right side of the first formed punch 31 is also just struck against sliding block
End face, then the first formed punch 31 pushes sliding block 13 and pipe embryo left side to move right formation upsetting shoulder on earth together, so far, first
Under the same movement of formed punch, undergauge and upsetting shoulder are completed together, further, in order to make the pipe fitting undergauge after processing reach requirement,
Using the further undergauge of 32 extruded tube embryo of the second formed punch 4, while second rushes core 322 to push shaft shoulder screw 21 and support core 22 to make described
Support core 22 is detached from pipe embryo 4, reaches the tube forming of requirement.
Fig. 1 to Figure 10 is please referred to, the present embodiment processes pipe embryo using above-mentioned molding die, comprising the following steps:
A., one above-mentioned molding die is provided；
B. clamping assembly 1 is mounted on the clamping machine of pipe end forming machine, by pipe embryo 4 be placed in upper mold 11 and lower die 12 it
Between, one end set of pipe embryo 4 is connected on the locating part 23 that in the support core 22 and end end abuts against on auxiliary rod assembly 2, is closed
Mould 11；
C. 31 punching press of the first formed punch is used, in the present embodiment, the first formed punch 31 is mounted on same pipe end forming machine
The first station on, 311 extruded tube embryo 4 of the first jumper bar allow pipe embryo 4 close to one end of undergauge groove enter undergauge groove carry out just
Secondary undergauge, while the other end of pipe embryo 4 completes upsetting shoulder, at this time locating part 23 by the upsetting shoulder groove 16 under pressure
4 position of pipe embryo is limited, support core 22, support core are not encountered in shift position, the punching press of the first formed punch 31 during punching press
The upsetting shoulder to be formed is propped up in 22 original positions, guarantees that upsetting shoulder is not recessed；
D. 32 punching press of the second formed punch is used, in order to remove the trouble of replacement formed punch from, the present embodiment is using there are two tools
Or the pipe end forming machine of more than two stations, when using different formed punch punching presses, it need to only adjust station and 1 type chamber of clamping assembly
With one heart, 32 extruded tube embryo 4 of the second formed punch allows the further undergauge on the second jumper bar 321 of pipe embryo 4, while second rushes core 322
Push shaft shoulder screw 21 and support core 22 that the support core 22 is made to be detached from pipe embryo 4, the pipe fitting as shown in Figure 10 for needing to process is completed, this
When only have the cap head of shaft shoulder screw 21 in whole or in part still in the inside of the pipe fitting processed, due to 21 diameter of shaft shoulder screw
Less than the internal diameter of pipe embryo 4, upper mold 11 is opened, easily removes the pipe fitting after processing, sliding block 13 is also in the driving of the first return unit 15
Under original position is slided in slideway, support core 22 resets under the driving of the second return unit 24, wait next pipe embryo 4 processing.
It should be noted that in the present embodiment, mold materials are Cr12MoV or other alternative materials, and
It requires to be heat-treated accordingly before material processing, details are not described herein again.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.

One end of undergauge groove enters undergauge groove and carries out first undergauge, while the other end of the pipe embryo (4) is under pressure
Upsetting shoulder is completed by the upsetting shoulder groove (16)；
D. the second formed punch (32) punching press is used, the second formed punch (32) extruded tube embryo (4) allows pipe embryo (4) to rush core second
(322) further undergauge on, while described second rushes core (322) shaft shoulder screw (21) and support core (22) is pushed to make the support core
(22) pipe embryo (4) are detached from.
