Description

Technical Field

[0001] This application relates to the field of powder metallurgy technology, and in particular to a door structure and a vacuum sintering furnace. Background Technology

[0002] Powder metallurgy is a process technology that uses metal powders (or mixtures of metal and non-metal powders) as raw materials, followed by shaping and sintering, to manufacture metallic materials, composites, and various types of products. Powder metallurgy shares similarities with ceramic production; therefore, a range of new powder metallurgy technologies can also be applied to the preparation of ceramic materials. Due to its advantages, powder metallurgy technology has become a key to solving new materials problems and plays a crucial role in the development of new materials.

[0003] In the sintering process of powder metallurgy, to make full use of space, a material bin for multi-layer feeding is generally installed inside the vacuum sintering furnace. This material bin has a door panel. When retrieving or loading material, workers need to hold the top edge of the door panel with one hand and hook the bottom edge with the other to remove or install it. However, since the bottom edge of the door panel usually abuts against the bottom wall of the furnace, it is difficult to hook the bottom edge, causing the door panel to easily slip. This not only risks damaging the door panel or other components but also increases the risk of injury to workers. Utility Model Content

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] Reference Figures 1 to 4 The first aspect of this application provides a box door structure, including a material box 100, a door panel 200, and a locking mechanism.

[0031] Reference Figure 1The material bin 100 is a rectangular structure with openings at both ends. A material cavity is located in the middle of the bin, communicating with the openings at both ends to facilitate material entry and exit. Furthermore, slots are symmetrically arranged on both sides of the material cavity for inserting material plates 110. Before sintering, the material plate 110 containing material is inserted through the opening and along the slot into the material cavity to allow material to be placed in. After sintering, the material plate 110 is slid outwards along the slot to remove the material. It is conceivable that multiple slots are arranged vertically and evenly, allowing for the sintering of more material and improving work efficiency.

[0032] Reference Figures 1 to 4 Door panels 200 are located at the openings at both ends of the material box 100 to close the openings. A support portion 120 extends outward from the bottom of the material box 100 from the opening, and the door panels 200 are mounted on the support portion 120. The support portion 120 supports the door panels 200, preventing them from slipping off the openings, reducing installation difficulty, and improving work efficiency.

[0033] Specifically, the door panel 200 includes an inner door panel 210 and an outer door panel 220. The inner door panel 210 is sealed to the material box 100, forming a closed space to ensure sintering stability and improve product quality. The outer door panel 220 is located on the side of the inner door panel 210 away from the material box 100, and is fixedly connected to the inner door panel 210. By fixing the outer door panel 220 and the inner door panel 210 together, they are modularly combined, facilitating the assembly and disassembly of the door panel 200. The structure is simple and the operation is convenient. It is easy to understand that the inner door panel 210 has a first fixing hole 230, and the outer door panel 220 has a second fixing hole 240. The first fixing hole 230 and the second fixing hole 240 are connected by fasteners 250. By adopting the above structure, the stability of the connection between the inner door panel 210 and the outer door panel 220 can be improved.

[0034] In this embodiment, the outer door panel 220 is provided with an operating part 260, which is used to operate the door panel 200 to open or close the opening. During operation, the operator can easily lift the door panel 200 off the material box 100 or lift the door panel 200 onto the material box 100 through the operating part 260, thereby opening or closing the opening. By providing the operating part 260, it is not only convenient for the operator to move the door panel 200, reducing labor intensity, but it also prevents the door panel from slipping and damaging the door panel 200 or other parts, ensuring the personal safety of the operator.

[0035] It is conceivable that the operating part 260 is configured as a groove integrally formed with the outer door panel 220. The groove is located at the lower part of the outer door panel 220. At this time, when handling, the worker uses one hand to act on the top edge of the door panel 200 and the other hand to insert into the groove to hold the lower part of the door panel 200, thereby removing the door panel 200 from the material box 100 or moving the door panel 200 onto the material box 100, reducing labor intensity.

[0036] Of course, the operating part 260 can also be set as a through hole, which can simplify the production process of the outer door panel 220, reduce production costs, and improve work efficiency.

[0037] It should be noted that the operating unit 260 can also be set in other positions on the door panel 200, as long as it is convenient for staff to move the door panel 200. This application does not restrict the location of the operating unit 260.

[0038] It should also be noted that the operating part 260 can also be configured as a handle. Those skilled in the art can make a reasonable choice according to the actual situation, and this application does not impose any restrictions on this.

[0039] Reference Figures 2 to 4 In a specific embodiment of this application, a sandwich channel 270 is provided between the inner door panel 210 and the outer door panel 220. The inner door panel 210 is provided with an airflow hole 280, and the sandwich channel 270 is connected to the airflow hole 280. Specifically, the material box 100 is provided with an air intake device, which is connected to the sandwich channel 270. Gas is sent into the sandwich channel 270 through the air intake device and enters the material cavity through the airflow hole 280, creating a pressure difference between the inside and outside of the material box 100, which promotes unidirectional gas flow and thus improves product quality. The inner door panel 210 is provided with a first air intake groove 271, and the outer door panel 220 is provided with a second air intake groove 272. When the inner door panel 210 and the outer door panel 220 are connected, the first air intake groove 271 and the second air intake groove 272 together define the sandwich channel 270, and the airflow hole 280 is provided in the first air intake groove 271. The first air inlet groove 271 and the second air inlet groove 272 cooperate to form a sandwich channel 270, which can increase the volume of the sandwich channel 270 so as to accommodate more gas.

[0040] It is conceivable that the inner door panel 210 is fitted to the end face of the material plate 110, and the airflow hole 280 corresponds to the material plate 110. By adopting the above structure, it is ensured that the gas passing through the airflow hole 280 is isolated from each other in each layer of material plate 110 in the material box 100, preventing gas from entering other material plates 110 from the end face of the material plate 110, so that the gas flowing out of the airflow hole 280 passes through each layer of material plate 110 in a predetermined manner, ensuring product quality.

[0041] It is easy to understand that an installation groove 290 is provided on the side of the inner door panel 210 away from the outer door panel 220. The installation groove 290 corresponds to the slot and is used together to place the material plate 110, thereby improving the stability of the material plate 110 and the tightness of the fit between the material plate 110 and the inner door panel 210. The installation groove 290 is staggered from the first air intake slot 271, thereby reducing the thickness of the inner door panel 210 and making the structure reasonable and compact.

[0042] It should be noted that the interlayer channel 270 may also be formed by only the first air inlet groove 271 or the second air inlet groove 272, and this application does not limit this.

[0043] Reference Figure 1 The locking mechanism is used to lock the door panel 200 onto the material box 100. Two locking mechanisms are provided, arranged vertically to improve the locking effect of the door panel 200. Of course, one, three, or other locking mechanisms can also be used; the number of locking mechanisms can be set according to specific circumstances.

[0044] Specifically, the locking mechanism includes a fixed base 310 and a locking rod 320. The fixed base 310 is disposed on both sides of the material box 100, with the cantilever end of the fixed base 310 extending towards the door panel 200. The locking rod 320 is connected to the cantilever end of the fixed base 310 and presses against the door panel 200, thus sealing the door panel 200 with the material box 100. During installation, the door panel 200 is placed over the opening, with the bottom of the door panel 200 abutting against the support part 120. Then, the locking rod 320 presses against the door panel 200, thereby achieving the installation of the door panel 200. The structure is simple and the operation is convenient.

[0045] As can be imagined, the cantilever end of the fixing base 310 is provided with a locking position 330, and the top of the locking position 330 is provided with a latch. The locking rod 320 is inserted into the locking position 330 along the latch to press against the door panel 200. In use, it is only necessary to insert the locking rod 320 from the latch into the locking position 330 or remove the locking rod 320 from the locking position 330 along the latch to press against or release the door panel 200, thereby locking or unlocking the door panel 200. The structure is simple and the operation is convenient. In particular, the cross-sectional area of ​​the locking position 330 gradually increases towards the latch side, thereby ensuring that the locking rod 320 presses firmly against the door panel 200, making the locking of the door panel 200 secure.

[0046] It should be noted that the fixing seat 310 can also be hinged to the material box 100. In this case, the fixing seat 310 drives the locking rod 320 to rotate, so that the locking rod 320 presses against the door panel 200, thereby locking the door panel 200. The structure is simple and the operation is convenient.

[0047] When it is necessary to open the opening, the worker takes out the locking rod 320 along the latch, at which point the door panel 200 is loosened. Then, one hand acts on the top edge of the door panel 200 and the other hand acts on the operating part 260 to remove the door panel 200 from the material box 100 for easy feeding or retrieval of materials. When it is necessary to close the opening, the worker acts on the top edge of the door panel 200 with one hand and the operating part 260 with the other hand to lift the door panel 200 and move it to the opening of the material box 100, so that the door panel 200 and the material box 100 are connected. Then, the locking rod 320 is inserted into the latch 330 along the latch, so that the locking rod 320 presses the door panel 200.

[0048] By providing an operating section 260 to the door panel 200, workers can easily remove the door panel 200 from or onto the material box 100 during installation or removal. This simplifies operation, reduces labor intensity, and prevents the door panel from slipping and damaging the door panel 200 or other components, ensuring worker safety. Furthermore, the locking mechanism allows the locking rod 320 to press the door panel 200 into place after it closes to the opening, creating a sealed connection between the door panel 200 and the material box 100. This facilitates locking the door panel 200, resulting in a simple structure and improved work efficiency.

[0049] A second aspect of this application provides a vacuum sintering furnace, including the door structure described in the first aspect of this application.

[0050] Applying the door structure described in the first aspect of this application to a vacuum sintering furnace, by providing an operating part 260 on the door panel 200, when installing or removing the door panel 200, the operator can use the operating part 260 to lift the door panel 200 off the material box 100 or move the door panel 200 onto the material box 100. This simplifies operation, reduces labor intensity, and also prevents the door panel from slipping and damaging the door panel 200 or other parts, ensuring the personal safety of the operator. By providing a locking mechanism, when the door panel 200 is closed in the opening, the locking rod 320 presses the door panel 200, making the door panel 200 and the material box 100 sealed together, thereby facilitating the locking of the door panel 200. The structure is simple and improves work efficiency.
