Description

Technical Field

[0001] The utility model relates to the technical field of powder metallurgy sintering, and more specifically to a powder metallurgy sintering device. Background Art

[0002] Powder metallurgy sintering device is a heat treatment equipment used to shape and sinter metal powder or a mixture of powder and non-metallic powder into metal or alloy parts. It is usually processed using a sintering furnace. The sintering furnace is usually composed of a herringbone belt conveyor mechanism and a heating mechanism. The metal parts are usually placed on a mesh tray, and then the mesh tray is placed on the herringbone belt conveyor mechanism. The metal tube on the mesh tray is conveyed into the heating mechanism through the herringbone belt conveyor mechanism for heat treatment. During the sintering process, the powder particles will flow, diffuse, melt and recrystallize with each other. These processes make the powder body further densified, thereby eliminating some or all of the pores therein.

[0003] However, the existing powder metallurgy sintering device will experience slag falling when heat treating metal parts. A part of the fallen residue will pass through the mesh tray and the herringbone belt conveyor mechanism, and then fall to the bottom of the sintering furnace. The staff is required to clean it regularly to prevent the accumulation of residue from affecting the atmosphere distribution in the furnace. The accumulation of residue at the bottom of the furnace may hinder the heat transfer, resulting in uneven temperature distribution in the furnace, which in turn affects the sintering effect. However, the fallen residue is located at the bottom of the sintering furnace and is too scattered, which makes it inconvenient for the staff to clean it. Utility Model Content

[0004] In order to overcome the above defects of the prior art, the utility model provides a powder metallurgy sintering device to solve the problem that the fallen residues in the above background technology are located at the bottom of the sintering furnace and are too scattered, making it inconvenient for the staff to clean them.

[0005] The utility model provides the following technical solutions: a powder metallurgy sintering device, comprising a sintering furnace body, the sintering furnace body comprising a herringbone belt conveying mechanism and a heating mechanism in the prior art, a collecting port is provided on one side close to the bottom of the sintering furnace body, a collecting box is provided at the inner bottom of the sintering furnace body, the collecting box is slidably matched with the collecting port and blocks the collecting port, the top of the collecting box is opened, a feeding port is provided at the bottom of the collecting box, a blocking component for blocking the feeding port is provided at the bottom of the collecting box, a cleaning component is provided in the collecting box, and a locking component for limiting the collecting box is provided on the outer side of the sintering furnace body.

[0006] Furthermore, the blocking assembly includes two sliders, a rotating rod, a torsion spring and a baffle. The two sliders are fixedly installed at the bottom of the collecting box and slidingly cooperate with the bottom of the sintering furnace body. The rotating rod is arranged between the two sliders. The two ends of the rotating rod are respectively rotatably connected to the two sliders. One side of the baffle is fixedly connected to the rotating rod. The torsion spring is sleeved on the rotating rod. One end of the torsion spring is fixedly connected to the baffle, and the other end is fixedly connected to one of the two sliders.

[0007] Furthermore, the cleaning assembly includes a rectangular groove, a scraper and a support rod. The rectangular groove is opened on one side of the collection box. The scraper is arranged in the rectangular groove and slides with the bottom and inner walls of the collection box on both sides. One end of the support rod is fixedly connected to the scraper, and the other end passes through the collection box and slides with the collection box.

[0008] Furthermore, the locking assembly includes a fixed rod and a limiting rod. The fixed rod is fixedly mounted on the sintering furnace body and is located above the collecting box. The limiting rod is sleeved on the fixed rod and rotatably connected to the fixed rod. The limiting rod slides with the side of the sintering furnace body.

[0009] Furthermore, a fixing block is fixedly mounted on one end of the support rod that passes through the collecting box.

[0010] Furthermore, a plurality of support columns are arranged at the bottom of the sintering furnace body.

[0011] Technical effects and advantages of the utility model:

[0012] According to the utility model, the baffle contacts the bottom of the sintering furnace body and blocks the discharge port. When the collecting port moves, it drives the two sliders, the rotating rod, the torsion spring and the baffle to move synchronously, so that the two sliders and the baffle move along the bottom of the sintering furnace body. When the baffle is no longer in contact with the bottom of the sintering furnace body, the torsion spring rebounds and drives the rotating rod and the baffle to rotate, so that the baffle no longer contacts the bottom of the collecting box. At this time, the baffle no longer blocks the discharge port. At this time, the baffle is in a vertical state with the ground. The residue in the collecting box is pushed to the discharge port through the cleaning component, and the material is discharged through the discharge port, which is convenient for the staff to clean the residue.

DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.

[0021] Figure 1 to Figure 6 It is the best embodiment of the utility model, and the following Figure 1 ~Attached Figure 6 The utility model is further described.

[0022] The utility model discloses a powder metallurgy sintering device, comprising a sintering furnace body 1, the sintering furnace body 1 comprises a herringbone belt conveying mechanism and a heating mechanism in the prior art, a collecting port 2 is provided on one side close to the bottom of the sintering furnace body 1, a collecting box 3 is provided at the bottom of the sintering furnace body 1, the collecting box 3 is slidably matched with the collecting port 2 and blocks the collecting port 2, the top of the collecting box 3 is opened, a feeding port 4 is provided at the bottom of the collecting box 3, a blocking component 5 for blocking the feeding port 4 is provided at the bottom of the collecting box 3, a cleaning component 6 is provided in the collecting box 3, and a locking component 7 for limiting the collecting box 3 is provided on one side outside the sintering furnace body 1.

[0023] In this embodiment, the herringbone belt conveying mechanism and the heating mechanism are both existing technologies and are not explained here. In the initial state, the collecting box 3 is located in the sintering furnace body 1, and the collecting box 3 is fixed inside the sintering furnace body 1 by the locking assembly 7. The blocking assembly 5 is contacted by the bottom of the sintering furnace body 1, so that the blocking assembly 5 blocks the discharge port 4. When in use, the staff places the parts on the mesh tray, and places the mesh tray on the herringbone belt conveying mechanism. The parts placed on the mesh tray are transported to the baking area through the herringbone belt conveying mechanism, and the parts on the mesh tray are heated by the heating mechanism. During the heating process, due to the effect of high temperature, the additives will decompose and volatilize. These substances may accumulate on the top of the furnace to form crystals. As time goes by, these crystals will gradually increase and may fall off by themselves. Part of the fallen residue will pass through the mesh tray and the herringbone belt conveying mechanism and fall into the collecting box 3. When the heating work is completed and the equipment is turned off, the staff will release the After the cleaning of the sintering furnace 3 is completed, the cleaning component 6 is manually restored to its original state, and the collecting box 3 is connected to the sintering furnace body 1 through the locking component 7.

[0024] Specifically, the blocking assembly 5 includes two sliders 501, a rotating rod 502, a torsion spring 503 and a baffle 504. The two sliders 501 are fixedly installed at the bottom of the collecting box 3 and slideably cooperate with the bottom of the sintering furnace body 1. The rotating rod 502 is arranged between the two sliders 501. The two ends of the rotating rod 502 are respectively rotatably connected to the two sliders 501. One side of the baffle 504 is fixedly connected to the rotating rod 502. The torsion spring 503 is sleeved on the rotating rod 502. One end of the torsion spring 503 is fixedly connected to the baffle 504, and the other end is fixedly connected to one of the two sliders 501.

[0025] In the present embodiment, in the initial state, the baffle 504 is in contact with the bottom of the sintering furnace body 1, and the baffle 504 blocks the discharge port 4. When the collecting box 3 moves, it drives the two sliders 501, the rotating rod 502, the torsion spring 503 and the baffle 504 to move synchronously, so that the two sliders 501 and the baffle 504 move along the bottom of the sintering furnace body 1. When the baffle 504 is no longer in contact with the bottom of the sintering furnace body 1, the torsion spring 503 rebounds and drives the rotating rod 502 and the baffle 504 to rotate, so that the baffle 504 is no longer in contact with the bottom of the collecting box 3. At this time, the baffle 504 no longer blocks the discharge port 4. At this time, the baffle 504 is at the ground In a vertical state, the residue in the collecting box 3 is pushed to the discharge port 4 through the cleaning component 6, and the material is discharged through the discharge port 4, which is convenient for the staff to clean the residue. When the residue is cleaned, the staff pushes the collecting box 3 into the sintering furnace body 1, and drives the two sliders 501, the rotating rod 502, the torsion spring 503 and the baffle 504 to move synchronously. When the vertical baffle 504 contacts the sintering furnace body 1, the baffle 504 is squeezed, so that the baffle 504 drives the rotating rod 502 to rotate, and the torsion spring 503 is deformed. When the baffle 504 is completely in contact with the bottom of the sintering furnace body 1, the baffle 504 blocks the discharge port 4.

[0026] Specifically, the cleaning component 6 includes a rectangular groove 601, a scraper 602 and a support rod 603. The rectangular groove 601 is opened on one side of the collection box 3. The scraper 602 is arranged in the rectangular groove 601 and slides with the bottom and the inner walls of the two sides of the collection box 3. One end of the support rod 603 is fixedly connected to the scraper 602, and the other end passes through the collection box 3 and slides with the collection box 3.

[0027] In this embodiment, when the collection box 3 moves and drives the scraper 602 and the support rod 603 to move synchronously, when the baffle 504 does not block the discharge port 4, the staff pulls the support rod 603, and the support rod 603 drives the scraper 602 to move, so that the scraper 602 scrapes the residue in the collection box 3, and the scraper 602 drives the residue to move toward the discharge port 4, so that the residue falls to the ground through the discharge port 4. When the cleaning is completed, the staff pushes the support rod 603, and the support rod 603 drives the scraper 602 to move into the rectangular groove 601. At this time, the staff cleans the residue that falls on the ground, which is convenient for the staff to clean.

[0028] Specifically, the locking assembly 7 includes a fixed rod 701 and a limiting rod 702. The fixed rod 701 is fixedly installed on the sintering furnace body 1 and is located above the collecting box 3. The limiting rod 702 is sleeved on the fixed rod 701 and is rotatably connected to the fixed rod 701. The limiting rod 702 slides with the side of the sintering furnace body 1.

[0029] In this embodiment, in the initial state, the limiting rod 702 resists the collecting box 3, so that the collecting box 3 is restricted in the sintering furnace body 1, and the collecting box 3 will not separate from the sintering furnace body 1. When the collecting box 3 needs to be taken out from the sintering furnace body 1, the staff rotates the limiting rod 702 so that the limiting rod 702 does not resist the collecting box 3. At this time, the staff pulls out the collecting box 3, and when the collecting box 3 enters into the sintering furnace body 1, the limiting rod 702 is rotated so that the limiting rod 702 resists the collecting box 3.

[0030] Specifically, one end of the support rod 603 that passes through the collecting box 3 is fixedly mounted with a fixing block 8 .

[0031] In this embodiment, the support rod 603 is more convenient to pull through the fixing block 8 .

[0032] Specifically, a plurality of support columns 9 are arranged at the bottom of the sintering furnace body 1 .

[0033] In this embodiment, a plurality of support columns 9 are provided to prevent the sintering furnace body 1 from contacting the ground, thereby keeping the sintering furnace body 1 stable.

[0034] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
