[0002] Thermally expanded graphite is a new type of material made through heating and expansion treatment. Expanded graphite is mainly based on graphite as raw material. After high-temperature treatment, it forms tiny voids and cracks in its crystal lattice structure, thereby reducing its density and increasing its volume. Furthermore, thermally expanded graphite can be used to perform thermoforming of metal pipes.
[0003] However, the existing thermoforming tooling for thermally expanded graphite-assisted metal pipe fittings has a low degree of automation, and often requires multiple manual operations during the processing, resulting in low processing efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a thermoforming fixture for thermally expanded graphite-assisted metal pipe fittings, comprising a box body, a first electric telescopic rod provided at the upper end of the box body, heating devices provided at the output end of the first electric telescopic rod and the bottom end of the box body, the output end of the heating devices being connected to a heating plate, a thermally expanded graphite box provided inside the box body, a conveying pipe provided on the thermally expanded graphite box, a material pump provided on the conveying pipe, and a nozzle connected to one end of the conveying pipe, a first electric slide rail provided inside the box body, a first electric slider provided on the first electric slide rail, a support plate fixedly connected to the upper end of the first electric slider, and an extrusion molding component provided at the upper end of the first electric slider, a mold block provided at the bottom end of the box body, and a pushing component provided on the side wall of the box body.

[0010] As a preferred embodiment of this utility model, a switch door is provided on one side of the box, and a transparent window is provided on the switch door.
[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are: By placing the metal pipe onto the upper part of the heating plate and simultaneously activating the first electric telescopic rod, the heating device and heating plate are moved downwards until both heating plates are in full contact with the metal pipe. Simultaneously, the material pump is activated, causing the thermally expanded graphite in the thermally expanded graphite tank to be sprayed into the metal pipe through the conveying pipe and nozzle. The heating device is also activated, allowing the heating plates to heat the metal pipe, causing the thermally expanded graphite inside to expand. The first electric telescopic rod is then activated again, moving the heating device and heating plate upwards. Simultaneously, the second electric slide rail and second electric slider are activated until the second electric slider moves to the appropriate position. Finally, the second electric telescopic rod is activated, moving the push plate until... The push plate contacts the metal tube on one side, and then the second electric slide rail and the second electric slider are activated. This allows the push plate to move the metal tube to one side until the metal tube is completely inserted into the first groove on the mold block through the support plate. Then, the first electric slide rail and the first electric slider are activated, causing the first electric slider to move the fixed plate and the hydraulic rod to one side until the punch on the hydraulic rod is aligned with the metal tube in the first groove. The hydraulic rod is then activated, causing the hydraulic rod to drive the punch to squeeze the metal tube. Under the action of the second groove, the metal tube can be effectively thermoformed. This device can automate the thermoforming of metal tubes and avoid the need for multiple manual operations during the processing, which would otherwise result in low processing efficiency.

However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation are all within the protection scope of this utility model without creative effort. Example
[0014] Please refer to Figure 1 , Figure 2 and Figure 4 As shown, this utility model provides a thermoforming tooling for thermally expanded graphite-assisted metal pipe fittings. The mold block 12 has a first groove 20 and a second groove 21. A control panel 22 is provided on one side of the box body 1, and a switch door 23 is provided on one side of the box body 1. A transparent window 24 is provided on the switch door 23. The device is connected to an external power source through an electric wire, thereby ensuring that the device can be used normally. All electrical equipment on the device is controlled by the control panel 22. As a further implementation of this embodiment, such as Figures 1-4As shown, a first electric telescopic rod 2 is installed at the upper end of the inner cavity of the box 1. Heating devices 3 are installed at the output end of the first electric telescopic rod 2 and at the bottom of the inner cavity of the box 1. A heating plate 4 is connected to the output end of the heating device 3. A thermal expansion graphite box 5 is installed inside the box 1. A conveying pipe 6 is installed on the thermal expansion graphite box 5. A material pump 7 is installed on the conveying pipe 6, and a nozzle 8 is connected to one end of the conveying pipe 6. A first electric slide rail 9 is installed inside the box 1. A first electric slider 10 is installed on the first electric slide rail 9. A support plate 11 is fixedly connected to the upper end of the first electric slider 10. The box 1 is equipped with an extrusion molding component, and a mold block 12 is provided at the bottom of the box 1. The box 1 is also equipped with a pushing component on its side wall. The extrusion molding component is as follows: a fixed plate 13 is fixedly connected to the upper end of the first electric slider 10, a hydraulic rod 14 is provided on the fixed plate 13, and a punch 15 is fixedly connected to the output end of the hydraulic rod 14. The pushing component is as follows: a second electric slide rail 16 is provided on one side of the inner wall of the box 1, a second electric slider 17 is provided on the second electric slide rail 16, a second electric telescopic rod 18 is provided on the second electric slider 17, and a push plate 19 is fixedly connected to the output end of the second electric telescopic rod 18.
[0015] In use, the metal pipe is placed on top of the heating plate 4, and the first electric telescopic rod 2 is activated. The first electric telescopic rod 2 moves the heating device 3 and the heating plate 4 downwards until the two heating plates 4 are in complete contact with the metal pipe. At the same time, the material pump 7 is activated, and the thermally expanded graphite in the thermally expanded graphite box 5 is sprayed into the metal pipe through the conveying pipe 6 and the nozzle 8. The heating device 3 is activated, so that the heating plate 4 heats the metal pipe, causing the thermally expanded graphite inside the metal pipe to expand. The first electric telescopic rod 2 is then activated, moving the heating device 3 and the heating plate 4 upwards. At the same time, the second electric slide rail 16 and the second electric slider 17 are activated until the second electric slider 17 moves to the appropriate position. Then, the second electric telescopic rod 18 is activated, moving the push plate 19 until the push plate 19 moves to the appropriate position. One side of the plate 19 contacts the metal tube, and the second electric slide rail 16 and the second electric slider 17 are activated. This allows the push plate 19 to move the metal tube to one side until the metal tube is completely inserted into the first groove 20 on the mold block 12 through the support plate 11. Then, the first electric slide rail 9 and the first electric slider 10 are activated, causing the first electric slider 10 to move the fixed plate 13 and the hydraulic rod 14 to one side until the punch 15 on the hydraulic rod 14 is aligned with the metal tube in the first groove 20. The hydraulic rod 14 is then activated, causing the hydraulic rod 14 to drive the punch 15 to squeeze the metal tube. Under the action of the second groove 21, the metal tube can be thermoformed effectively. This device can automate the thermoforming of metal tubes and avoid the need for multiple manual operations during the processing, which would result in low processing efficiency.
[0016] Specific working principle: In use, the metal pipe is placed on the upper end of the heating plate 4, and the first electric telescopic rod 2 is activated simultaneously. The first electric telescopic rod 2 drives the heating device 3 and the heating plate 4 downward until the two heating plates 4 are in complete contact with the metal pipe. At the same time, the material pump 7 is activated, and under the action of the material pump 7, the thermally expanded graphite in the thermally expanded graphite box 5 is sprayed into the metal pipe through the conveying pipe 6 and the nozzle 8. At the same time, the heating device 3 is activated, so that the heating plate 4 heats the metal pipe, causing the thermally expanded graphite inside the metal pipe to expand due to heat. Then, the first electric telescopic rod 2 is activated again, which drives the heating device 3 and the heating plate 4 upward. At the same time, the second electric slide rail 16 and the second electric slider 17 are activated until the second electric slider 17 moves to the appropriate position. Finally, the second electric telescopic rod 18 is activated to drive the push plate 19 to move. Until one side of the push plate 19 contacts the metal tube, the second electric slide rail 16 and the second electric slider 17 are activated, which allows the push plate 19 to move the metal tube to one side until the metal tube is completely inserted into the first groove 20 on the mold block 12 through the support plate 11. Then the first electric slide rail 9 and the first electric slider 10 are activated, which causes the first electric slider 10 to move the fixed plate 13 and the hydraulic rod 14 to one side until the punch 15 on the hydraulic rod 14 is aligned with the metal tube in the first groove 20. The hydraulic rod 14 is then activated, which causes the hydraulic rod 14 to drive the punch 15 to squeeze the metal tube. Under the action of the second groove 21, the metal tube can be thermoformed effectively. This device can automate the thermoforming of metal tubes and avoid the need for multiple manual operations during the processing, which would result in low processing efficiency.
