The first mold groove 121 passes through the upper mold plate 12 in the horizontal direction, and the groove space of the first mold groove 121 is set in a semicircular shape with an opening facing downward in cross section. The positioning column 15 passes through the first mold groove 121, and the outer surface of the positioning column 15 is separated from the inner wall of the first mold groove 121 by a certain distance. The guide plate 13 is provided with a guide hole (not shown in the figure), and the guide hole passes through the guide plate 13 in the vertical direction.

[0027] The lower die 20 includes a bottom plate 21, two positioning plates 22 mounted on the bottom plate 21, a limiting seat 24 slidably disposed between the positioning plates 22 and the bottom plate 21, a lower die plate 23 fixedly mounted on the limiting seat 24, a plurality of die protrusions 25 extending into the interior of the lower die plate 23, and a plurality of adjusting members 26 mounted on the limiting seat 24. The adjusting members 26 correspond to the die protrusions 25 one by one, and the bottom of the protrusion is limited by the limiting seat 24 or the adjusting members 26. A second die groove 231 is disposed on the lower die plate 23. By adjusting the position of the adjusting member 26 on the lower die plate 23, the length of the die protrusion 25 extending into the second die groove 231 can be further adjusted.

[0028] Specifically, the second die groove 231 of the lower template 23 is arranged at a position close to the upper end surface of the lower template 23, and the groove shape of the second die groove 231 is arranged in the opposite direction to the groove shape of the first die groove 121. A receiving groove 232 is provided at the bottom of the lower template 23, and a plurality of through holes 233 are also provided on the lower template 23, and the through holes 233 are used to connect the second die groove 231 and the receiving groove 232.

[0029] A locking plate 22 is provided at the bottom of the limiting seat 24, and the cross-section of the locking plate 22 is set in an inverted T shape. The bottom plate 21 and the two locking plates 22 form a slot 27 that is wide inside and narrow outside. The locking plate 22 is inserted into the slot 27 in the horizontal direction. The limiting seat 24 and the lower template 23 installed on the limiting seat 24 can slide along the extension direction of the slot 27.

[0030] The position limiting seat 24 is provided with a plurality of notches near the upper end surface, and a position limiting surface 242 is formed at the bottom of the notch.

In addition, the position limiting seat 24 is also provided with a plurality of position limiting holes 243, and the position limiting holes 243 correspond to the position limiting surfaces 242 one by one, and the position limiting holes 243 extend to the position limiting surfaces 242, and the extension direction of the position limiting holes 243 is perpendicular to the position limiting surfaces 242. The hole wall of the position limiting hole 243 is provided with an internal thread, and the outer side surface of the position adjusting member 26 is provided with an external thread.

[0031] During assembly, the upper end of the limiting seat 24 is inserted into the receiving groove 232, the die convex 25 passes through the through hole 233 and extends into the second die groove 231, the adjusting member 26 is installed on the internal thread of the limiting hole 243 through the external thread, and the bottom of the die convex 25 is against the limiting surface 242. When processing the functional groove on the surface of the metal tube 100, the metal tube 100 is first sleeved on the positioning column 15, and the driving assembly drives the upper die 10 to press down, so that the metal tube 100 extends downward into the second die groove 231, the upper die plate 12 fits with the lower die plate 23, the positioning column 15 supports the metal tube 100 from the inside, and the die convex 25 extending into the second die groove 231 squeezes the metal tube 100 from the outside, thereby processing the functional groove on the metal tube 100.

[0032] When the processing depth of the functional groove needs to be adjusted, the adjusting member 26 is rotated to extend from the limiting surface 242 and push the die protrusion 25, and the limiting of the die protrusion 25 by the limiting surface 242 is adjusted to the limiting of the die protrusion 25 by the adjusting member 26, thereby changing the depth of the die protrusion 25 extending into the second die groove 231.

[0033] In addition, in order to facilitate the removal of the metal tube 100 from the mold, the utility model also includes two guide columns 32 and two springs 31.

When the mold is opened, the driving assembly releases the upper mold 10, and the spring 31 pushes open the guide plate 13 to separate the upper mold plate 12 from the lower mold plate 23.

[0034] In addition, the utility model also includes a fixed seat 41 and a clamping column 42 slidably mounted on the fixed seat 41.

After the lower template 23 is adjusted on the bottom plate 21, the clamping column 42 and the clamping hole 234 are arranged opposite to each other, and the clamping column 42 is slid to make the clamping column 42 clamp into the clamping hole 234, thereby limiting the lower template 23.

[0035] The beneficial effect of the pipe-making mold with adjustable processing depth of the utility model is that: by arranging a limiting surface 242, an adjusting member 26 and a die protrusion 25 on the lower mold 20, the position of the adjusting member 26 on the limiting seat 24 is adjustable, and the die protrusion 25 passes through the through hole 233 of the limiting seat 24 and extends into the second die groove 231. When processing the functional groove, it is possible to choose to limit the die protrusion 25 by the limiting surface 242 or by the adjusting member 26, thereby changing the depth of the die protrusion 25 extending into the second die groove 231. The overall structure is flexible and adaptable.
