Description

Technical Field

[0001] The utility model relates to the field of copper powder sintering production, and particularly relates to a prechamber of a copper powder sintering diffusion furnace. Background Art

[0002] The copper powder sintering process is to place copper powder in a mold with a specific shape, and then place the mold together in a high-temperature sintering furnace filled with a protective gas, so that the copper powder particles are fused into an irreversible block. This process has been widely used in the fields of heat pipe manufacturing, VC vapor chamber manufacturing, etc.

[0003] The high consumption of a large amount of protective gas and high energy consumption in copper powder sintering have always troubled production enterprises. The main reason is that an old-fashioned tunnel kiln without a gate is used. To prevent product oxidation problems, the current existing processing method is to use a large amount of protective gas (such as nitrogen, nitrogen-hydrogen mixture) to isolate the copper powder from the air. The processing technology is rough and the loss is relatively large.

[0040] A turnover device 40, the discharge end of the turnover device 40 is arranged perpendicular to the side of the feeding device A20 in the horizontal direction and is used to transfer the materials to the feeding device A20.

[0041] Specifically, in this patent, by setting the displacement chamber 10 at the feed port of the diffusion furnace (pusher furnace), connecting the discharge gate 102 to the feed port of the diffusion furnace, and providing a through hole 1021 on the discharge gate 102 to use the protective gas in the pusher furnace to displace the air entering the displacement chamber 10 during feeding or discharging, the waste of the protective gas is reduced. At the same time, the carrier plate and the materials can be preheated by the heated protective gas, improving the heat utilization rate. In addition, a turnover device 40 is provided, which can horizontally push the carrier plate of the materials onto the feeding device A20 to achieve continuous feeding.

[0042] Furthermore, a transition table 202 is arranged on one side of the feeding device A20 to connect the discharge end of the turnover device 40;

The horizontal cylinder A502 is fixedly connected to the end of the guide rod of the lifting cylinder A501. A push block A503 is fixedly connected to the end of the guide rod of the horizontal cylinder A502. Among them, the horizontal cylinder A502 is arranged below the conveying surface of the chain conveyor table A201. When the guide rod of the lifting cylinder A501 extends in place, the horizontal cylinder A502 can push the material on the chain conveyor table A201 into the set position in the replacement chamber 10;

[0046] The pusher device B60 includes a lifting cylinder B601 and a horizontal cylinder B602. The lifting cylinder B601 is fixedly connected inside the chain conveyor table B401. The horizontal cylinder B602 is fixedly connected to the end of the guide rod of the lifting cylinder B601.

In the turnover device 40, the lifting cylinder B601 lifts the horizontal cylinder B602, and the guide rod of the horizontal cylinder B602 drives the push block B603 to push the carrier plate into the pusher device A50. Subsequently, the chain conveyor table A201 moves, sends the carrier plate to the feeding gate 101, the lifting cylinder A501 lifts the horizontal cylinder A502, and the guide rod of the horizontal cylinder A502 drives the push block A503 to push the carrier plate into the replacement chamber 10 to complete the feeding. At the same time, in order to facilitate the detection of the position, a proximity switch can be set (not shown in this patent, which is a conventional technical means in the art and will not be elaborated).

[0048] Furthermore, the feeding device B30 includes a hydraulic cylinder 301 which is fixedly connected to the outside of the replacement chamber 10. Its guide rod is inserted into the replacement chamber 10, and a push plate 302 is fixedly connected to the end for pushing the material out of the replacement chamber 10.

[0049] Specifically, after the gas replacement in the replacement chamber 10 is completed, the discharge gate 102 is opened, and the guide rod of the hydraulic oil 301 pushes the carrier plate into the push plate furnace (not shown in the figure) for heating.

[0051] Specifically, when opening the gate, the guide rod of the lifting cylinder 1013 retracts upward, and the lifting frame 10131 moves upward along the door frame 1011, causing the gate plate 10133 to move upward, thus opening the gate. When closing the gate, the guide rod of the lifting cylinder 1013 extends and moves downward, and the lifting frame 10131 moves downward along the door frame 1011. Since the gate plate 10133 is rotatably connected to the lifting frame 10131 through the rotating plate 10132, after the lifting frame 10131 moves in place, the gate plate 10133 can be squeezed by the rotating plate 10132, which can make the gate plate 10133 better squeeze the door frame 1011 to form a better seal (a sealing rubber pad can be set on the gate plate for a better sealing effect).

[0052] Furthermore, in order to better guide and ensure the movement stability of the lifting frame 10131, a guide rod 103111 is also fixedly connected to the lifting frame 10131.
