When the pipe fitting is specifically machined, the punching knives on two sides of the positioning pipe 200 can move towards the die core pipe 300, and the pipe fitting is inserted into the die core pipe 300, so that the punching knives can punch the pipe wall of the pipe fitting, so that the slotted holes are machined on the peripheral surface of the pipe fitting, but some specific pipe fittings need to punch a plurality of slotted holes on the peripheral surface of the pipe fitting, and the number of the cutters is generally two, so that after one-time punching is completed, the position of the pipe fitting needs to be adjusted, so that the corresponding pipe wall surface of the pipe fitting faces towards the punching knives, and then secondary punching or multiple punching is performed.

The positioning tube 200 is vertically disposed on the base 100, and the tube can be sleeved on the positioning tube 200, and the positioning tube 200 is fixed, which plays a positioning role.

The mold core tube 300 is sleeved on the positioning tube 200, and a clamping portion (not shown) for fixing a pipe fitting is formed between the mold core tube 300 and the positioning tube 200, so that when the pipe fitting is installed, the pipe fitting can be inserted into the mold core tube 300, and then the mold core tube 300 is sleeved outside the positioning tube 200.

The mold core tube 300 is detachably sleeved on the positioning tube 200, and since the mold core tube 300 is a tube body structure, a tube to be processed can be inserted into the mold core tube 300, then the mold core tube 300 is sleeved on the positioning tube 200 together with the tube, at this time, the tube is located at a clamping portion between the mold core tube 300 and the positioning tube 200, and the positioning tube 200 passes through the tube to support the tube, so that the tube can be punched after being fixed by the positioning tube 200 and the mold core tube 300.

The base 100 is provided with at least two indexing grooves 110, the die core tube 300 is provided with locking blocks 310, and it is worth to be noted here that the number of the indexing grooves 110 is greater than or equal to the number of the locking blocks 310, for example, when one locking block 310 is provided, the number of the indexing grooves 110 may be two or more, and when two locking blocks 310 are provided, the number of the indexing grooves 110 may be two or more, specifically, when the number of the indexing grooves 110 is at least two, the die core tube 300 can be locked at two different angular positions; theoretically, there are as many indexing slots 110 as possible to lock the core tube 300 in as many positions as there are corresponding numbers of indexing slots 110, for example, there are N indexing slots 110, and the core tube 300 can be at most N angular positions, so that N faces of the tube can be aligned with the cutter.

And each of the indexing grooves 110 is arranged in a ring shape, and the locking blocks 310 are disposed in the indexing grooves 110 to restrict the rotation of the die core barrel 300.

Preferably, the indexing grooves 110 are required to be arranged in a ring shape, the indexing grooves 110 are arranged around the positioning tube 200, when the mold core tube 300 is sleeved outside the positioning tube 200, the locking block 310 arranged at the lower end of the mold core tube can be embedded into one group of the indexing grooves 110, so that one pipe wall of the pipe fitting in the mold core tube 300 is aligned with the cutter, when the locking block 310 is embedded into the other group of the indexing grooves 110, the other pipe wall of the pipe fitting is aligned with the cutter, so that the locking block 310 and the indexing grooves 110 can be locked, the circumferential position of the mold core tube 300 is positioned, and during secondary punching, the positioning is not required to be performed, the wall surface to be processed of the pipe fitting can be aligned with the cutter only by embedding the locking block 310 into the other indexing groove 110, so that the indexing effect is achieved.

From the point of view of the overall structure, the die core tube 300 needs to be sleeved outside the positioning tube 200 so as to fix the pipe fitting in the clamping portion, and at this time, the die core tube 300 and the pipe fitting can also rotate around themselves, but this may cause the forming hole 320 on the die core tube 300 not to be aligned with the cutter, so that the locking block 310 needs to be embedded in the first indexing groove 110, so as to ensure that the cutter is aligned with the first forming hole 320 of the die core tube 300; after punching, the core tube 300 is lifted and then rotated to adjust the angle thereof, and the locking block 310 is embedded in the second indexing groove 110, so that the cutter can align with the second forming hole 320 of the core tube 300 without repositioning, and then a second set of slots is punched in the tube wall of the tube.

In summary, the locking blocks 310 are able to cooperate with the indexing slots 110 in different positions and allow the core tube 300 to be locked in at least two set angular positions, thereby indexing the tube about its axis, thus enabling the tube to be machined in separate passes without requiring repositioning.
