[0026] Embodiment

[0027] AsFigures 1-3 As shown in the figure, this embodiment provides a special-shaped pipe pressing machine, which includes a base 1. Inside the base 1, there is an oil tank 61 placed. A fuel pump 62 is fixedly installed by bolts on the upper part of the oil tank 61. The fuel pump 62 pumps the oil in the oil tank 61 into the oil cylinder 3 to drive the oil cylinder 3 to work. On the surface of the base 1, a main frame 2 is fixedly installed by bolts. An oil cylinder 3 is fixedly installed by bolts on the upper part inside the main frame 2. The oil cylinder 3 is connected to the fuel pump 62 through a pipeline to form an oil circuit. At the output end of the oil cylinder 3, a main die support block 4 is fixedly installed by bolts. One end of the main die support block 4 away from the oil cylinder 3 is in an inverted "V" shape structure. An upper die assembly 51 is arranged at the bottom of the main die support block 4. A lower die assembly 52 is arranged at the position corresponding to the upper die assembly 51 at the bottom of the main frame 2. A loading port 21 is arranged between the upper die assembly 51 and the lower die assembly 52 on the side of the main frame 2. The upper die assembly 51 is driven by the oil cylinder 3 and can move away from or close to the lower die assembly 52. When the upper die assembly 51 moves away from the lower die assembly 52, the pipe fitting can enter from the loading port 21 on the side of the main frame 2. Then the oil cylinder 3 drives the main die support block 4 to move downward, driving the upper die assembly 51 to move downward, so that the upper die assembly 51 and the lower die assembly 52 are closed to form a circle and gradually shrink to complete the pipe pressing operation.

[0028] Specifically, the upper die assembly 51 includes an upper fixing block 511, upper connecting blocks 512 and upper transition blocks 513. One end of the upper fixing block 511 is fixedly connected to the main die support block 4. There are two upper connecting blocks 512, and the two upper connecting blocks 512 are respectively movably connected to both sides of the upper fixing block 511. There are two upper transition blocks 513, and the two upper transition blocks 513 are respectively movably connected to the side of the upper connecting block 512 away from the upper fixing block 511. The upper fixing block 511 is fixed on the main die support block. When the upper connecting blocks 512 and the upper transition blocks 513 on both sides are squeezed, they move towards the upper fixing block 511, so that the upper fixing block 511, the upper connecting blocks 512 and the upper transition blocks 513 form a semi-circular structure.

[0029] In addition, the lower mold assembly 52 includes a lower fixed block 521, a lower connecting block 522 and a lower transition block 523, one end of the lower fixed block 521 is connected to the bottom of the main frame 2, there are two lower connecting blocks 522, and the two lower connecting blocks 522 are respectively movably connected to the two sides of the lower fixed block 521, and there are two lower transition blocks 523, and the two lower transition blocks 523 are respectively movably connected to the side of the lower connecting block 522 away from the lower fixed block 521; similarly, the lower fixed block 521 is fixed to the bottom of the main frame 2, when the cylinder 3 drives the upper mold assembly 51 to move downward, first the upper transition block 513 and the lower transition block 523 contact, push the lower transition block 523 and the lower connecting block 522 to move in the direction of the lower fixed block 521, and finally close to form a semicircular structure, which is combined with the upper mold assembly 51 to form a circular structure, so as to perform a pipe pressing operation on the pipe fittings located in the upper mold assembly 51 and the lower mold assembly 52.

[0030] Furthermore, a plurality of positioning posts 514 are fixedly connected to one end of the upper transition block 513 close to the lower transition block 523, and a positioning groove 524 is provided at a position of the lower transition block 523 corresponding to the positioning posts 514. In this embodiment, there are two positioning posts 514 and two positioning grooves 524, which are respectively arranged on both sides of the upper transition block 513 and the lower transition block 523, wherein the positioning post 514 is a cylindrical structure, and the positioning groove 524 is a semicircular groove structure. When the upper transition block 513 moves toward the lower transition block 523, the positioning post 514 is embedded in the positioning groove 524, so that the upper transition block 513 and the lower transition block 523 are accurately embedded to avoid misalignment.

[0031] Furthermore, the upper fixed block 511 and the upper connecting block 512, and the upper connecting block 512 and the upper transition block 513 are connected via an upper return spring 515, and the lower fixed block 521 and the lower connecting block 522, and the lower connecting block 522 and the lower transition block 523 are connected via a lower return spring 525. In normal state, the upper return spring 515 uses its own elastic force to push the upper fixed block 511, the upper connecting block 512 and the upper transition block 513 apart from each other. When the upper mold assembly 51 and the lower mold assembly 52 are in contact and closed, the upper return spring 515 is squeezed and contracted. At this time, the upper fixed block 511, the upper connecting block 512 and the upper transition block 513 are closed together. When the oil cylinder 3 drives the upper fixed block 511 to move upward, the upper mold assembly 51 and the lower mold assembly 52 are separated. At this time, the upper return spring 515 recovers through its own elastic force and pushes the upper connecting block 512 and the upper transition block 513 to return to their original positions. The working principle of the lower return spring 525 is the same as that of the upper return spring 515.

[0032] Wherein, an upper backing plate 516 is fixedly connected to the connection part between the main mold carrier block and the upper mold assembly 51, and a lower backing plate 526 is fixedly connected to the connection part between the main frame 2 and the lower mold assembly 52. The upper backing plate 516 and the lower backing plate 526 are used for auxiliary guiding. Moreover, the surfaces of the upper backing plate 516 and the lower backing plate 526 are polished to make them smoother, so that the relative movement between the upper mold assembly 51 and the main mold carrier block is smoother.

[0033] Wherein, upper mold baffles 517 are arranged on both sides of the upper mold assembly 51. The upper mold baffles 517 are fixedly connected to the main mold carrier block 4. Lower mold baffles 527 are arranged on both sides of the lower mold assembly 52. The lower mold baffles 527 are fixedly connected to the main frame 2. The upper mold assembly 51 and the lower mold assembly 52 are limited on both sides by the upper mold baffles 517 and the lower mold baffles 527, so that they can only move in the up and down direction to avoid deviation.

[0034] Furthermore, an electronic ruler 71 is fixedly connected to the inside of the main frame 2 by bolts. A piston fixing plate 72 is fixedly connected to the side surface of the main mold carrier block 4 by bolts. One end of the piston fixing plate 72 is fixedly connected to the output end of the electronic ruler 71. The direction of the ruler rod (output end) of the electronic ruler 71 and the piston (output end) of the oil cylinder 3 are arranged in parallel. When the oil cylinder 3 drives the main mold carrier block 4 to move up and down, the ruler rod of the electronic ruler 71 is driven to move up and down, so as to accurately measure the stroke of the activity of the oil cylinder 3, which is convenient for control.

[0035] Furthermore, a lifting ring 8 is fixedly welded to the top end of the main frame 2. It is convenient to connect a lifting hook through the lifting ring 8 for transfer.

[0036] The working principle of the present utility model: The oil cylinder 3 drives the main mold carrier block 4 to move upward, so that the upper mold assembly 51 and the lower mold assembly 52 are separated. The special-shaped pipe fitting is placed through the feeding port 21 on the side surface of the main frame 2. Then, the oil cylinder 3 drives the main mold carrier block 4 to move downward, driving the upper mold assembly 51 and the lower mold assembly 52 to contact and close to form a continuously shrinking circular structure. The pipe pressing operation is completed during the shrinking process. Finally, the oil cylinder 3 drives the upper mold assembly 51 and the lower mold assembly 52 to separate, and the pipe fitting can be taken out.

[0037] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them; although the present disclosure has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present disclosure.
