Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy technology, and in particular to a powder metallurgy material loading device. Background Technology

[0002] Powder metallurgy is an industrial technology that produces metal materials, composite materials, and various types of products by taking metal powders or using metal powders (or mixtures of metal and non-metal powders) as materials, and then forming and sintering them. Currently, powder metallurgy material loading mainly relies on manual labor, which is not only inefficient but also prone to problems due to the randomness, uncertainty, and low precision of manual operation. This often results in the material being placed too close to the boat wall, making it easy for the material to stick to the boat wall during sintering. Furthermore, close proximity between material piles often leads to sintered blanks sticking together, while large distances can cause sintering failure, resulting in poor quality sintered products. Utility Model Content

[0003] The purpose of this invention is to provide a powder metallurgy material loading device that enables rapid loading of powder metallurgy materials while arranging the material piles at set intervals, and simultaneously ensuring an effective distance between the material piles and the boat wall.

[0004] To achieve the above objectives, this utility model provides the following solution:

The limiting frame is located on the outer periphery of the placement plate and is connected to the placement plate.

[0020] The present invention achieves the following technical advantages over the prior art:

[0021] This utility model provides a novel and reasonable powder metallurgy material loading device. By opening loading holes on the loading plate of the material loading limiting device and setting the interval between any two adjacent loading holes to meet a predetermined interval, it enables the material piles in the sintering boat to be placed at the set intervals. This overcomes the interval errors caused by purely manual loading, preventing the sintered billets from sticking together due to excessively small intervals or sintering failure due to excessively large intervals, thus improving the quality of sintered products. Simultaneously, the limiting frame, located on the outer periphery of the loading plate, has a certain width and acts as a limit, ensuring that the loading holes at the outer edge of the loading plate maintain a certain interval with the boat wall. This prevents the material piles placed through the loading holes at the outer edge of the loading plate from being too close to the boat wall, which would cause the boat wall to stick to the material during sintering, further improving the quality of sintered products. Furthermore, the material loading limiting device has a simple structure, is easy to use, and enables rapid loading and unloading, thus improving loading efficiency.

[0022] In some technical solutions disclosed in this utility model, the powder metallurgy material charging device is also equipped with a sand flattening device. Through the combined use of the sand flattening device and the material placement limiting device, not only can the material pile be quickly and accurately discharged, but the sand can also be quickly compacted before discharge, ensuring the flatness of the sand layer, which can further improve the charging effect and sintering quality. Moreover, whether the sand flattening device and the material placement limiting device are used together or independently, they are easy to operate, ensuring the charging effect while improving charging efficiency.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] One of the objectives of this invention is to provide a powder metallurgy material loading device that enables rapid loading of powder metallurgy materials while simultaneously ensuring that the material piles are arranged at set intervals and maintaining an effective distance between the material piles and the boat wall. This avoids adhesion between materials and between materials and the boat wall during the sintering process, thereby improving the quality of sintered products and solving the problems existing in the prior art.

[0032] Another objective of this invention is to provide a powder metallurgy material loading device, which, in addition to a material placement limiting device, also includes a sand flattening device to compact and flatten the sand in the sintering boat before material loading, thereby further improving the quality of the sintered products.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Example 1

[0035] like Figure 1As shown, this embodiment provides a powder metallurgy material loading device 100, including a material placement limiting device 1 and a handheld component. The material placement limiting device 1 is used to place the material inside a sintering boat. The material placement limiting device 1 includes a limiting frame 11 and a placement plate 12. The placement plate 12 has multiple placement holes 13, and any one placement hole 13 penetrates the thickness direction of the placement plate 12. The interval 14 between any two adjacent placement holes 13 satisfies a set interval. It should be noted that the set interval here is determined according to the sintering process and is related to the material composition and... The sintering requirements of the final sintered product are related to this. This set interval is an ideal interval that can be estimated by those skilled in the art based on the actual sintering process. When processing the material placement plate 12 of this solution, the spacing between the holes 13 can be processed into a set interval value according to different sintering requirements. This set interval is not a fixed value, but can be flexibly adjusted according to different sintering process requirements, and material placement plates 12 of different specifications can be made. The material placement plate 12 of this solution can be used to ensure that the material pile is stacked according to the preset interval, but cannot determine the size of the preset interval. The aforementioned limiting frame 11 is located on the outer periphery of the stacking plate 12 and is connected to the stacking plate 12. The outer contour of the limiting frame 11 is adapted to the contour of the sintering boat wall (i.e., the inner wall of the sintering boat). When in use, the limiting frame 11 and the stacking plate 12 are placed into the sintering boat simultaneously. The limiting frame 11 mainly contacts and engages with the boat wall through its outer contour. The limiting frame 11 has a certain width to limit the material flow, ensuring that the stacking holes 13 on the outer edge of the stacking plate 12 are kept at a certain distance from the boat wall. This prevents the material pile placed through the stacking holes 13 on the outer edge of the stacking plate 12 from being too close to the boat wall, which could lead to sintering adhesion. At least one of the aforementioned limiting frame 11 and the stacking plate 12 is provided with a handle to facilitate personnel holding the stacking plate 12 for transfer and use.

[0036] In some embodiments, the shape and size of the placement holes 13 can be flexibly set according to different sintering processes. The shape of the placement holes 13 includes, but is not limited to, circles, polygons (triangles, rectangles, or pentagons, etc.). The shapes of the placement holes 13 on the placement plate 12 can be the same or different, and the sizes of the placement holes 13 can be the same or different. At the same time, the distribution of the placement holes 13 on the placement plate 12 can be regularly and evenly distributed or randomly distributed, as long as the interval 14 between any two adjacent placement holes 13 meets the set interval. As a preferred embodiment, in order to facilitate the processing and production of the placement plate 12, it is preferable that the shape and size of the placement holes 13 on the placement plate 12 are consistent, for example, the placement holes 13 are circular holes, and the placement holes 13 are evenly distributed on the placement plate 12.

[0037] In some embodiments, the structure of the material handling plate 12 includes, but is not limited to, a rectangular material handling plate, a circular material handling plate, etc. Taking a rectangular plate as an example, the material handling holes 13 on it can be arranged in a regular matrix or a circular array. Generally, in order to improve the utilization rate of the material handling plate 12 and the material feeding efficiency, it is preferable that the shape of the material handling plate 12 and the array arrangement of the material handling holes 13 are consistent, such as... Figure 1 As shown, the material placement plate 12 is rectangular, and the material placement holes 13 are arranged in a matrix. The uniform distribution of the material placement holes 13 can improve the uniformity, accuracy and efficiency of material placement.

[0038] In some embodiments, the shapes of the limiting frame 11 and the material handling plate 12 can be the same or different. For example, the limiting frame 11 can be a rectangular frame, while the material handling plate 12 can be a circular plate inscribed within the limiting frame 11. To achieve multiple loading volumes at once, it is preferable to make efficient use of the space within the limiting frame 11, that is, to set the shapes of the limiting frame 11 and the material handling plate 12 to be the same, such as... Figure 1 As shown, both the limiting frame 11 and the sway plate 12 are rectangular structures. Regardless of whether the shapes of the limiting frame 11 and the sway plate 12 are the same or different, they can be connected by means of integral molding, welding or clamp assembly.

[0039] In some embodiments, to facilitate processing and eliminate the assembly process of the limiting frame 11 and the stacking plate 12, thereby improving sintering efficiency, it is preferable that the limiting frame 11 and the stacking plate 12 are integrally formed, that is, the limiting frame 11 and the stacking plate 12 are located on the same plate structure, such as... Figure 1 As shown, the overall plate containing the limiting frame 11 and the material shovel plate 12 is rectangular, and a ring of gaps is reserved around the outer periphery of the rectangular material shovel hole array on it. This gap is the limiting frame 11.

[0040] In use, with the handheld component facing upwards and the material placement plate 12 facing downwards, the operator holds the handheld component and places the rectangular material placement limiting device 1 onto the sand laid inside the sintering boat. At this time, the outer contour of the limiting frame 11 is in clearance fit with the wall of the sintering boat. Then, an appropriate amount of sintered material is placed into each of the placement holes 13 of the material placement plate 12. After placement, the material placement limiting device 1 is removed vertically upwards, and a uniformly distributed array of materials is placed on the sand laid inside the sintering boat.

[0041] As described above, this solution has a novel and reasonable structure. By opening material placement holes on the material placement plate of the material placement limiting device and setting the interval between any two adjacent placement holes to meet the set interval, it can realize that the material piles in the sintering boat are placed at the set interval, overcoming the interval error caused by purely manual loading. It can avoid the sintered billets sticking due to too small an interval between materials or the sintering failure due to too large an interval between materials, thus improving the quality of sintered products. At the same time, the limiting frame is located on the outer periphery of the material placement plate. The limiting frame has a certain width and plays a limiting role, which can keep the material placement holes on the outer edge of the material placement plate at a certain interval from the boat wall. This avoids the material piles placed through the material placement holes on the outer edge of the material placement plate being too close to the boat wall, which would cause the boat wall to stick to the material during sintering, further improving the quality of sintered products. In addition, the material placement limiting device has a simple structure and is easy to use, which can realize rapid loading and unloading and efficient loading, thereby improving loading efficiency. This solution is mainly applicable to powder metallurgy products, especially suitable for loading small-sized powder metallurgy balls, powder metallurgy blocks, powder metallurgy columns, and other materials.

[0042] Example 2

[0043] like Figure 1 As shown, the powder metallurgy material loading device 100 proposed in this embodiment is also equipped with a sand flattening device 2. The sand flattening device 2 includes a flattening plate 21 and a second handheld component. The flattening plate 21 is used to flatten the sand in the sintering boat for subsequent material placement. The second handheld component is set on the flattening plate 21 and is connected to the first handheld component so that the flattening plate 21 and the material placement plate 12 are arranged opposite each other and form an integral structure. In use, the flattening plate 21 can be used to flatten the sand in the sintering boat first. Then, the powder metallurgy material loading device 100 is flipped and turned upside down. The material placement limiting device 1 is then placed face down on the sand in the sintering boat for loading. Then, sand is laid on the placed material, and finally, the above operation is repeated to achieve layer-by-layer loading of sand and material in the sintering boat. The flattening plate 21 is mainly used to flatten the sand at the bottom of the boat and the sand covering the surface of each material.

[0044] In some embodiments, the second handpiece and the first handpiece can be integrally formed or welded together, or they can be detachably connected. The detachable connection method is more flexible and can facilitate the separation and independent use of the sand flattening device 2 and the material placement limiting device 1 without affecting the integrated use of the sand flattening device 2 and the material placement limiting device 1.

[0045] In some embodiments, the flattening plate 21 and the limiting frame 11 are preferably identical in shape and size, and are arranged vertically aligned. This design ensures that both the flattening plate 21 and the limiting frame 11 are adapted to the wall of the sintering boat, facilitating positioning and guidance by the boat wall when the flattening plate 21 or the material handling plate 12 is placed into the sintering boat, thus enabling rapid and accurate placement of the flattening plate 21 or the material handling plate 12 within the sintering boat. Based on the above structure, the first handheld component includes multiple handheld rods 15, with multiple handheld rods 15 arranged on the side of the limiting frame 11 facing the flattening plate 21. Correspondingly, the second handheld component includes multiple handheld rods 22, with multiple handheld rods 22 arranged on the side of the flattening plate 21 facing the limiting frame 11. The first handheld rod 15 and the second handheld rod 22 correspond one-to-one, and any one of the first handheld rods 15 is plugged into and engaged with the corresponding second handheld rod 22. Handheld lever 15 and handheld lever 22 are detachably connected by a plug-in mechanism, which ensures connection strength while allowing for quick separation and independent use.

[0046] In some embodiments, such as Figure 1 As shown, the limiting frame 11 is a rectangular limiting frame, with a hand-held lever 15 at each of its four corners; correspondingly, the flattening plate 21 is a rectangular plate, with a hand-held lever 22 at each of its four corners. Each hand-held lever 15 has a plug-in structure 1 at its end, and each hand-held lever 22 has a plug-in structure 2 at its end that is compatible with the plug-in structure 1; one of the plug-in structures 1 and 2 is a plug-in hole, and the other is a plug-in block compatible with the plug-in hole.

[0047] In some embodiments, each hand lever 15 is preferably welded to or integrally formed with the limiting frame 11; at the same time, each hand lever 22 is preferably welded to or integrally formed with the flattening plate 21.

[0048] In this embodiment, the powder metallurgy material loading device 100 is used by first assembling the sand flattening device 2 and the material placement limiting device 1 together through the insertion of the first hand lever 15 and the second hand lever 22. Then, the sand flattening device 2 is placed face down into the sintering boat, and the sand laid in the sintering boat is compacted and flattened using the flattening plate 21. Then, the powder metallurgy material loading device 100 is taken out, and the material placement limiting device 1 is placed face down on the compacted sand in the sintering boat for loading. After loading is completed, a layer of sand is covered on the placed material, and then the above-mentioned operation of compacting with the flattening plate 21 and releasing material with the material placement limiting device 1 is repeated to achieve layer-by-layer loading of sand and material in the sintering boat until the set number of material layers in the sintering boat are completed.

[0049] The aforementioned powder metallurgy material loading device, through the combined use of a sand flattening device and a material placement limiting device, not only enables rapid and precise material discharge from the material pile but also allows for rapid compaction of the sand before discharge, ensuring a smooth sand layer and further improving the loading effect and sintering quality. Moreover, whether the sand flattening device and the material placement limiting device are used together or independently, they are easy to operate, ensuring loading effectiveness while improving loading efficiency. This solution is mainly applicable to powder metallurgy products, especially suitable for loading small-sized powder metallurgy balls, powder metallurgy blocks, and powder metallurgy columns.
