The surface of the chip body 7 is in contact with the inner wall of the guiding tube 502, and the bottom of the guiding tube 502 is in contact with the top of the metal flange body 1.

[0029] In this embodiment: By placing the chip body 7 to be sintered with the metal flange body 1 inside the guiding hopper 501, the chip body 7 can slide down inside the guiding tube 502 to the exact center position at the top of the metal flange body 1, which is convenient for subsequent sintering between the core metal flange bodies 1. By placing the chip body 7 at the exact center position at the top of the metal flange body 1, during the heating process, the center position of the chip body 7 can receive heat more evenly, which helps to ensure the consistency and quality of sintering, and helps to make each part of the chip body 7 receive relatively uniform pressure when applying pressure, improving the reliability of sintering.

[0030] Specifically, as shown in Figure 1 and Figure 2 , a slot 6 is opened on the left side of the top of the metal flange body 1, and a plug board 3 is arranged on the left side of the top of the metal flange body 1. The plug board 3 is movably inserted into the slot 6.

[0031] Specifically, as shown in Figure 3 , chamfers are opened on the front side and the rear side of the bottom of the plug board 3.

[0032] Specifically, as shown in Figure 3 , a pull ring 8 is fixedly connected to the top of the plug board 3, and the left side of the fixing plate 4 is fixedly connected to the right side of the plug board 3.

[0033] In this embodiment: By opening chamfers on the front side and the rear side of the bottom of the plug board 3, holding the pull ring 8 can conveniently insert the plug board 3 into the slot 6, thereby limiting the fixing plate 4 and making the sliding hole 9 located at the top of the center of the metal flange body 1.

[0034] Specifically, as shown in Figure 1 , Figure 3 and Figure 4 , a sliding hole 9 is opened in the fixing plate 4, and the guide tube 502 is slidably connected to the inside of the sliding hole 9.

[0035] Specifically, as shown in 1 and Figure 4 , pulling blocks 10 are fixedly connected to the front side and the rear side of the guide tube 502, and the bottom of the pulling block 10 contacts the top of the fixing plate 4.

[0036] In this embodiment: By sliding the guide tube 502 inside the sliding hole 9 and holding the pulling block 10, the guide tube 502 can be conveniently inserted into and pulled out of the sliding hole 9.

[0037] Specifically, as shown in Figure 6 , a protective layer 14 is sprayed on the surface and the inner wall of the guide hopper 501 and the guide tube 502, and the material of the protective layer 14 is polyurethane paint.

[0038] Specifically, as shown in Figure 1 and Figure 5 , a pressing plate 11 is movably arranged inside the guide tube 502. A pressing rod 12 is fixedly connected to the top of the pressing plate 11, a grip ball 13 is fixedly connected to the top of the pressing rod 12, and the bottom of the pressing plate 11 contacts the top of the chip body 7.

[0039] In this embodiment: By spraying a protective layer 14 made of polyurethane material on the inner walls and surfaces of the guiding hopper 501 and the guiding tube 502, the inner walls of the guiding hopper 501 and the guiding tube 502 can be made smooth and wear-resistant, facilitating the downward sliding of the chip body 7 on the inner walls of the guiding hopper 501 and the guiding tube 502. By holding the grip ball 13, the pressing plate 11 can be moved into the guiding tube 502 to press the chip body 7.

[0040] Working principle: By inserting the insertion plate 3 into the slot 6, the fixing plate 4 can be connected to the metal flange body 1, facilitating the positioning of the sliding hole 9 at the exact center of the top of the metal flange body 1. Then, the guiding tube 502 is inserted into the sliding hole 9, making the bottom of the guiding tube 502 contact the top of the metal flange body 1. At this time, the chip body 7 to be sintered with the metal flange body 1 can be moved into the guiding hopper 501, and the chip body 7 can move through the guiding hopper 501 into the guiding tube 502 and then fall to the exact center of the top of the metal flange body 1. By spraying a protective layer 14 made of polyurethane coating material on the inner walls of the guiding hopper 501 and the guiding tube 502, the inner walls of the guiding hopper 501 and the guiding tube 502 can be made smooth and wear-resistant, facilitating the downward sliding of the chip body 7. Then, hold the grip ball 13 and insert the pressing plate 11 into the guiding tube 502, press down the pressing plate 11 until it contacts the chip body 7. Then, hold the pulling block 10 and pull the guiding tube 502 upward, making the inner wall of the guiding tube 502 disengage from the surface of the chip body 7. Then, move the guiding tube 502 and the pressing plate 11 upward together, making the guiding tube 502 disengage from the sliding hole 9, and then disengage the insertion plate 3 from the slot 6, so that the chip body 7 is at the exact center of the top of the metal flange body 1, which facilitates the subsequent sintering of the chip body 7 and the metal flange body 1. During the heating and sintering process, the central position of the chip body 7 can receive heat more evenly, which helps to ensure the consistency and quality of sintering. It helps to make each part of the chip body 7 receive relatively uniform pressure when applying pressure, improving the reliability of sintering, and avoiding the problem that in some existing specific experimental or small-scale production environments, the chip is sintered after being manually placed on the top of the metal flange. Manually placing the chip is not convenient to place the chip at the exact center of the top of the metal flange, affecting the sintering effect of the chip and the metal flange.

[0041] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
