Description

Technical Field

[0001] This utility model relates to the field of bimetallic sheet powder spreading and sintering technology, specifically a powder spreading device for metal-based dispersed solid self-lubricating material sheets. Background Technology

[0002] Copper-steel bimetallic sheets, as a high-performance composite material, combine the friction-reducing, corrosion-resistant, and conductive properties of the copper alloy layer with the high strength and impact resistance of the steel matrix. This material typically uses low-carbon steel or low-alloy steel (such as Q355 steel) as the matrix to provide structural support and mechanical strength, while the copper alloy layer is enhanced with elements such as lead and tin to improve its anti-galling, friction-reducing, and conductive properties. To further improve the friction-reducing effect, a certain proportion of friction-reducing materials are also mixed into the copper layer powder.

[0003] However, both powder spreading machines and manual scraping methods have limitations in manufacturing such bimetallic sheets. Traditional powder spreading machines are limited by the fluidity of copper powder, making it difficult to ensure uniform spreading. More importantly, when solid lubricants such as graphite are added to the metal matrix to improve friction reduction, the graphite floats during the powder spreading process, resulting in a lower-than-expected graphite content in the actual sheet, thus weakening the friction reduction performance of the final product. On the other hand, while manual scraping allows for more precise control of powder distribution, it is inefficient and unsuitable for large-scale, multi-specification production, significantly limiting production capacity and increasing costs. Therefore, a powder spreading device for metal-based dispersed solid self-lubricating material sheets is proposed. Utility Model Content

[0025] 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.

[0026] Please see Figure 1-4 In this embodiment of the invention, a powder spreading device for a metal-based dispersed solid self-lubricating material plate includes:

[0027] Base 2, on which an electromagnetic chuck 3 is mounted;

[0028] Two guide rail structures are set on the base 2, and ball sliders 7 are slidably installed on the outer peripheral surface of the two guide rail structures.

[0029] The fixed plate 6 is connected to two ball bearing sliders 7 respectively. A scraper 8 is provided between the fixed plate 6 and the electromagnetic chuck 3, which can be adjusted in height. The scraper 8 is connected to the fixed plate 6 through an adjusting component. When adjusting the distance between the scraper 8 and the plate, the scraper 8 connected to it can be adjusted synchronously by adjusting the height of the adjusting component.

[0030] Specifically, the electromagnetic chuck 3 is fixedly installed in the middle area of ​​the upper surface of the base 2, which can flatten the slightly warped plate and ensure the uniformity of the powder coating thickness. The two guide rail structures are symmetrically arranged on both sides of the upper surface of the base 2 and are parallel to each other, providing a stable moving path for the fixed plate 6. The two ends of the fixed plate 6 are connected to the ball slider 7 by bolts, which not only ensures the stability of the structure, but also facilitates subsequent disassembly and maintenance.

[0031] The fixing plate 6 has a through hole 61 and a first internal threaded hole 62. The tension bolt 9 passes through the through hole 61 and is threaded to the scraper rod 8, which has a second internal threaded hole 81. The tightening bolt 10 is threaded to the first internal threaded hole 62. The plate is placed directly above the electromagnetic chuck 3. When the electromagnetic chuck 3 is powered on, it can firmly attract and fix the plate. The length of the scraper rod 8 is greater than the width of the plate, ensuring that the entire surface of the plate can be completely covered during the powder laying process, achieving uniform leveling. The thickness of the powder can be precisely adjusted by controlling the height of the scraper rod 8 through the adjusting component: when the scraper rod 8 rises, the distance between it and the plate increases, and the powder thickness increases accordingly; when the scraper rod 8 falls, the distance decreases, and the powder thickness becomes thinner, thereby achieving flexible control of the powder layer thickness.

[0032] In addition, the device uses a direct powder application method, eliminating the need for powder spreading, which effectively avoids problems such as floating and dust generation of powder (such as powder containing graphite) during operation, thus improving the working environment.

[0033] Through the above scheme, the coordinated action of the guide rail structure, the fixed plate 6 and the ball slider 7 effectively restricts and guides the movement direction of the scraper 8, ensuring smooth and linear operation of the powder scraping process; at the same time, combined with the cooperation of the adjusting component and the fixed plate 6, the height of the scraper 8 can be flexibly adjusted to adapt to the needs of powder laying of different thicknesses, improving the convenience of operation and the controllability of the process.

[0034] Please see Figure 1 In one embodiment, preferably, the guide rail structure includes two support seats 4 disposed at the corners of the base 2. The two support seats 4 are connected by a guide rod 5. The ball slider 7 is slidably sleeved on the outer periphery of the guide rod 5. Furthermore, the support seats 4 are fixed to the corners of the base 2 by bolts. The guide rod 5 connects the two support seats 4 and is the moving path of the ball slider 7. The ball slider 7 has a lower coefficient of friction and requires less effort, making it easier for workers to pull the scraper 8 with less force.

[0035] Please see Figure 1 In one embodiment, preferably, the outer peripheral surface of the guide rod 5 is fitted with two sets of telescopic protective covers 13 connected to the ball slider 7, and the ends of the two sets of telescopic protective covers 13 away from the ball slider 7 are respectively connected to two support seats 4. Furthermore, both ends of the telescopic protective covers 13 are connected to the ball slider 7 and the support seats 4 by bolts, which facilitates subsequent replacement. The presence of the telescopic protective covers 13 can prevent powder from adhering to the outer peripheral surface of the guide rod 5, thereby increasing the friction and making operation more laborious.

[0036] Please see Figure 4In one embodiment, preferably, the adjusting component includes a tension bolt 9, which passes through the fixing plate 6 and is threadedly connected to the scraper rod 8. An adjusting nut 15 threadedly connected to the tension bolt 9 is rotatably connected to the fixing plate 6. Furthermore, the number of adjusting nuts 15 is the same as the number of tension bolts 9. By rotating the adjusting nuts 15 on the fixing plate 6, the tension bolt 9 is driven to rise and fall vertically, thereby driving the scraper rod 8 threadedly connected to the tension bolt 9 to rise and fall synchronously.

[0037] Please see Figure 4 In one embodiment, preferably, a tightening bolt 10 is installed on the fixing plate 6. The end of the tightening bolt 10 passes through the fixing plate 6 and keeps in contact with the upper surface of the scraper 8. Furthermore, since the adjusting nut 15 is rotatably connected to the fixing plate 6, it may loosen during the pulling of the scraper 8, causing the height of the scraper 8 to change. By rotating the tightening bolt 10, its end is pressed against the upper part of the scraper 8, which can prevent the scraper 8 from moving upward. At the same time, the downward pressure applied by the tightening bolt 10 to the scraper 8 is transmitted to the adjusting nut 15, thereby locking the adjusting nut 15 and preventing it from loosening.

[0038] Please see Figure 1 In one embodiment, preferably, a handle 11 is installed on the fixing plate 6 to facilitate the worker to move the scraper 8 by holding the handle 11.

[0039] Please see Figure 1 In one embodiment, preferably, a base frame 1 is mounted on the lower surface of the base 2 to provide stable support for the base 2.

[0040] Please see Figure 1 In one embodiment, preferably, the electromagnetic chuck 3 is provided with a material picking groove 31. The number of material picking grooves 31 is not limited. In this embodiment, preferably, there are two material picking grooves 31, which makes it convenient to remove the board from the electromagnetic chuck 3 after the powder is laid.

[0041] Please see Figure 1 In one embodiment, preferably, a powder leakage groove 21 is provided on one side of the upper surface of the base 2, and a receiving box 12 is installed below the powder leakage groove 21 on the base 2. The top and one side of the receiving box 12 are open structures (without a lid), which facilitates the insertion of the receiving box. When the receiving box is full of powder, it can be pulled out horizontally from the side of the receiving box 12 for easy cleaning and replacement.

[0042] Please see Figure 1 In one embodiment, preferably, a baffle plate 14 is provided along the edge of the upper surface of the base 2 to prevent excess powder from spilling onto the ground.

[0043] The working principle and usage process of this utility model are as follows: Place the plate to be powdered flat on the electromagnetic chuck 3, and then open the electromagnetic chuck 3 to the magnetic suction state. The plate will adhere tightly to the electromagnetic chuck 3 due to the magnetic attraction. Adjust the nut 15, the tightening bolt 10 and the tension bolt 9 according to the required powdering thickness. Use a feeler gauge to measure the gap between the scraper 8 and the plate to be powdered until the required gap is reached. When in use, push the handle 11 to push the scraper 8 away from the powder leakage groove 21. The plate will adhere tightly to the electromagnetic chuck 3 due to the magnetic attraction. Then, spread the prepared powder evenly on the plate. This will prevent the graphite from floating due to the falling powder. Slowly pull the handle 11, and the scraper 8 will spread the powder evenly on the surface of the plate. After spreading the powder, close the magnetic attraction and open the demagnetization. After demagnetization, slowly lift the powdered plate and put it into the sintering furnace. Excess powder will fall from the powder leakage groove 21 into the receiving box in the receiving box 12.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
