Description

Technical Field

[0001] This utility model relates to the field of metal smelting equipment technology, and in particular to a metal ingot scraping device. Background Technology

[0002] In the lead smelting industry, during the ingot casting process, a pouring device injects molten metal into a mold. After cooling and demolding, the metal ingot is placed on a conveyor chain for transport. During the molding process, burrs form on the surface of the metal ingot, affecting its appearance quality. Current methods for removing burrs involve manual scraping with tools, but the freshly demolded ingot is still very hot, posing a risk of burns to workers and requiring significant physical exertion. Summary of the Invention

[0003] To address the problem of high labor intensity in manually cleaning burrs from metal ingots, this invention proposes a metal ingot scraping device. After the metal ingot on the conveyor chain is lifted by a lifting and clamping mechanism, the scraping mechanism removes the burrs from the metal ingot, reducing the workload of workers.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A metal ingot scraping device for scraping burrs off metal ingots on two conveyor chains, comprising a base, a lifting and clamping mechanism, a support and a scraping mechanism;

[0006] The lifting and clamping mechanism is located between the two conveyor chains. The lifting and clamping mechanism includes a first telescopic member, a support plate, and a clamping member. The first telescopic member is fixed on the base, the support plate is fixed on the output end of the first telescopic member extending upward, and the clamping member is fixed on the end of the support plate for clamping the metal ingot. The lifting and clamping mechanism lifts and clamps the metal ingots on the two conveyor chains.

[0007] A power assembly is fixed on the support, and the scraping mechanism is slidably mounted on the support and located on the upper side of the metal ingot. The power assembly drives the scraping mechanism to move between two conveyor chains to scrape off burrs on the metal ingot.

[0008] Preferably, the scraping device further includes a positioning mechanism located in front of the lifting and clamping mechanism, between the two conveyor chains. The positioning mechanism includes a second telescopic member and a first positioning plate. The second telescopic member is fixed to the base, and the first positioning plate is fixed to the upwardly extending output end of the second telescopic member. A limit plate is fixed on the first positioning plate to block the metal ingots. The limit plate serves two purposes: firstly, it blocks the metal ingots, allowing each metal ingot to be scraped sequentially; secondly, the limit plate corrects the position of any metal ingots placed on the conveyor chains that may be slightly tilted.

[0009] Preferably, the limiting plate is perpendicular to the conveyor chain. The limiting plate ensures that the metal ingot is placed perpendicular to the length of the conveyor chain in front of the ingot support plate, preventing instability in the clamping of the metal ingot on the support plate.

[0010] Preferably, a second positioning plate is fixed on the bracket, and the second positioning plate is located on the upper side of the metal ingot. When the lifting and clamping mechanism clamps and lifts the metal ingot to the lower side of the scraping mechanism, the second positioning plate positions the height of the metal ingot to ensure the height position of the scraping mechanism for scraping the metal ingot.

[0011] Preferably, the scraping mechanism includes a fixed support and a scraper assembly. The fixed support is fixed to the output end of the power component. The scraper assembly includes a scraper seat and a scraper disposed at the lower end of the scraper seat. The scraper seat is disposed on the lower side of the fixed support, and the position of the scraper relative to the scraper seat is adjustable.

[0012] Preferably, scraper assemblies are provided on both sides of the fixed support.

[0013] Preferably, the lower end of the scraper holder has a strip-shaped groove, and the scraper is equipped with bolts. The bolts pass through the scraper and the strip-shaped groove in sequence and are then screwed with nuts. The extending direction of the strip-shaped groove is consistent with the conveying direction of the conveyor chain.

[0014] Preferably, one end of the scraper seat is rotatably mounted on a fixed support, and the fixed support is further provided with an elastic component, which includes a first elastic seat, a limiting rod, a spring, and a second elastic seat.

[0015] The upper end of the first elastic seat is rotatably connected to the fixed support, and the lower end of the second elastic seat is rotatably connected to the scraper seat. The upper end of the limiting rod passes through the first elastic seat and its end is fixed with a first limiting member, while the lower end of the limiting rod passes through the second elastic seat and its end is fixed with a second limiting member. The spring is sleeved on the limiting rod, with its upper end contacting the first elastic seat and its lower end contacting the second elastic seat. The upper side of a metal ingot is usually not flat and may have some unevenness. The elastic component adapts to these unevennesses, thereby improving the scraping effect on the edges of the metal ingot.

[0016] Preferably, a positioning wheel is rotatably mounted on the side of the scraper holder, and the positioning wheel contacts the upper surface of the metal ingot. When the scraper cleans the metal ingot, the positioning wheel remains in contact with the upper surface of the metal ingot, ensuring that the distance between the scraper and the metal ingot remains consistent and preventing the scraper from being too high or too low.

[0017] Preferably, a first rotating shaft is fixed to one end of the fixed support, the first rotating shaft passes through the scraper seat, a second rotating shaft is fixed to one side of the scraper seat, the second rotating shaft passes through the second elastic seat, a third rotating shaft is fixed on the first elastic seat, a sleeve is fixed on the fixed support, and the end of the third rotating shaft extends into the sleeve.

[0018] The beneficial effects of this utility model through the above technical solution are as follows:

[0019] 1. In this utility model, the first telescopic component of the lifting and clamping mechanism drives the ingot support plate to lift the metal ingot on the conveying chain, and the clamping component clamps the metal ingot. After the first telescopic component moves the metal ingot to a suitable height, the power component on the bracket drives the scraping mechanism to move between the two conveying chains to scrape off the burrs on the metal ingot.

[0020] 2. In the positioning mechanism of this utility model, the second telescopic component drives the first positioning plate at its upper end to move upward. After moving to a certain height, the limiting plate at the upper end of the first positioning plate contacts the side of the metal ingot and stops it on the conveyor chain. At the same time, the limiting plate is perpendicular to the conveyor chain, so that the metal ingot is placed in front of the ingot support plate and is perpendicular to the length direction of the conveyor chain, ensuring the subsequent lifting and clamping mechanism's clamping work on the metal ingot.

[0021] 3. The scraper on the scraper seat at the lower end of the fixed support of the scraper mechanism of this utility model is adjustable, which improves the application range of the scraper mechanism; at the same time, an elastic component is also provided on the fixed support. One end of the scraper seat is rotatably mounted on the fixed support, and the first elastic seat and the second elastic seat on the elastic component are rotatably mounted on the fixed support. When the scraper contacts the unevenness of the edge of the metal ingot, the scraper seat and the elastic component are compressed, so that the scraper can adaptively adjust according to the unevenness of the metal ingot.

[0022] 4. The present invention has a positioning wheel rotatably mounted on the scraper seat. When the scraper cleans the metal ingot, the positioning wheel will always be in contact with the upper surface of the metal ingot, ensuring the distance between the scraper seat and the metal ingot, thereby ensuring that the distance between the scraper and the metal ingot is consistent and preventing the scraper from being stuck and broken when it encounters the uneven parts of the metal ingot.

[0038] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0039] like Figures 1-10As shown, this embodiment provides a metal ingot scraping device for scraping burrs off the edges of metal ingots (lead ingots) 200 on two conveyor chains 100 of a conveyor. The metal ingots (lead ingots) 200 are located between the two conveyor chains 100. The device includes a base 1, a lifting and clamping mechanism 2, a bracket 3, and a scraping mechanism 4. (See reference...) Figure 1 The base 1 is located on the lower side of the conveyor, between the two conveyor chains 100, and the bracket 3 is fixed to the support body of the conveyor by bolts.

[0040] The lifting and clamping mechanism 2 is located between the two conveyor chains 100, for reference. Figures 3-6 The lifting and clamping mechanism 2 includes a first telescopic member 21, a support plate 22, and a clamping member 23. The first telescopic member 21 is fixed to the base 1 by bolts. The support plate 22 is bolted to the output end of the first telescopic member 21 extending upward. The clamping member 23 is fixed to the end of the support plate 22 and is used to clamp the metal ingot 200. There are two clamping members 23, which are welded and fixed to both ends of the support plate 22 respectively. The first telescopic member 21 can be a cylinder or a hydraulic cylinder. The clamping member 23 is a finger cylinder. Each clamping member 23 can clamp the lower end of the metal ingot 200 independently. It is purchased externally and is existing technology.

[0041] The scraping device also includes a positioning mechanism 5, which is located in front of the lifting and clamping mechanism 2. The positioning mechanism 5 and the lifting and clamping mechanism 2 are arranged sequentially along the conveying direction of the conveying chain 100. The positioning mechanism 5 is located between the two conveying chains 100. (Reference) Figures 3-4 The positioning mechanism 5 includes a second telescopic member 51 and a first positioning plate 52. The second telescopic member 51 is welded and fixed to the base 1, and the first positioning plate 52 is welded and fixed to the output end of the second telescopic member 51 extending upward. A limit plate 53 is fixed on the first positioning plate 52 to block the metal ingot 200. In this embodiment, the length direction of the limit plate 53 is perpendicular to the conveying direction of the conveying chain 100.

[0042] The second telescopic component 51 can be a cylinder or a hydraulic cylinder; the limiting plate 53 serves to block the metal ingots 200, allowing each metal ingot 200 to be scraped off in succession; on the other hand, the metal ingots 200 placed on the conveyor chain 100 will be slightly tilted. Through the contact between the limiting plate 53 and the side of the metal ingot 200, under the driving action of the conveyor chain 100, it is ensured that the metal ingots 200 can be perpendicular to the conveyor chain 100 in the top view, thereby ensuring that the metal ingots 200 can be stably clamped by the clamping component 23 on the ingot support plate 22.

[0043] refer to Figure 1A second positioning plate 32 is fixed on the bracket 3, and the second positioning plate 32 is located on the upper side of the metal ingot 200. The first telescopic member 21 moves the upper surface of the metal ingot 22 to contact the lower surface of the second positioning plate 32, ensuring that the height position of the scraping mechanism on the scraping edge of the metal ingot 200 remains consistent.

[0044] In this embodiment, a proximity switch sensor, model Pepperl+Fuchs GLV18-8-450-73-120, is also provided on the support body of the conveyor. It is fixed in a preset position. When it detects the metal ingot 200 on the conveyor chain 100, the second telescopic member 51 drives the first positioning plate 52 at its upper end to move upward. After moving a certain height, the limiting plate 53 at the upper end of the first positioning plate 52 contacts the side of the metal ingot 200 and stops it on the conveyor chain 100. After it is perpendicular to the conveyor chain 100, the second telescopic member 51 retracts, and the metal ingot 200 falls back onto the conveyor chain 100. After moving a certain distance, the first telescopic member 21 drives the ingot support plate 22 to lift the metal ingot 200 on the conveyor chain 100, and the clamping member 23 clamps the metal ingot 200. The first telescopic member 21 moves the metal ingot 22 to a suitable height, and the subsequent scraping work on the metal ingot 200 can begin.

[0045] refer to Figure 7 A power assembly 31 is fixed on the support 3. The power assembly 31 can be a rodless cylinder, which is purchased externally. The scraping mechanism 4 is slidably mounted on the support 3 and located above the metal ingot 200. The power assembly 31 drives the scraping mechanism 4 to move between the two conveyor chains 100 to scrape off burrs on the metal ingot 200. The scraping mechanism 4 is fixed on the slider of the rodless cylinder. When the power assembly 31 is activated, the scraping mechanism 4 moves with the slider.

[0046] refer to Figures 8-10 The scraping mechanism 4 includes a fixed support 41 and a scraper assembly. In this embodiment, scraper assemblies are provided on both sides of the fixed support 41. The fixed support 41 is fixed to the output end of the power assembly 31 and is fixed to the slider of the rodless cylinder by bolts. The scraper assembly includes a scraper seat 42 and a scraper 43 disposed at the lower end of the scraper seat 42. The scraper seat 42 is disposed on the lower side of the fixed support 41, and the position of the scraper 43 relative to the scraper seat 42 is adjustable.

[0047] For details, please refer to Figure 9The lower end of the scraper holder 42 is provided with a strip groove 421, the extension direction of which is consistent with the conveying direction of the conveyor chain 100. The scraper 43 is provided with a bolt 422, which passes through the scraper 43 and the strip groove 421 from bottom to top and is then screwed with a nut. When dealing with metal ingots of different sizes, the nut can be turned to adjust the position of the bolt 422 in the strip groove 421, thereby adjusting the horizontal distance between the scraper 43 and the metal ingot 200.

[0048] In another embodiment, one end of the scraper seat 42 is rotatably mounted on the fixed support 41. Specifically, one end of the fixed support 41 is fixed with a first rotating shaft 411, which passes through the scraper seat 42. The scraping mechanism 4 also includes an elastic component, which is mounted on the fixed support 41. The elastic component includes a first elastic seat 44, a limiting rod 45, a spring 46, and a second elastic seat 47.

[0049] The upper end of the first elastic seat 44 is rotatably connected to the fixed support 41. A third rotating shaft 441 is welded and fixed to the first elastic seat 44. A sleeve 412 is welded and fixed to the fixed support 41. The end of the third rotating shaft 441 extends into the sleeve 412. The lower end of the second elastic seat 47 is rotatably connected to the scraper seat 42. A second rotating shaft 423 is fixed to one side of the scraper seat 42. The second rotating shaft 423 passes through the second elastic seat 47. The upper end of the limiting rod 45 passes through the first elastic seat 44 and its end is fixed with a first limiting member 48. The lower side of the first limiting member 48 contacts the upper side of the first elastic seat 44. The lower end of the limiting rod 45 passes through the second elastic seat 47 and its end is fixed with a second limiting member 49. The upper side of the second limiting member 49 contacts the lower side of the second elastic seat 47. The spring 46 is sleeved on the limiting rod 45. The upper end of the spring 46 contacts the first elastic seat 44 and the lower end contacts the second elastic seat 47.

[0050] The metal ingot 200 has some uneven edges. When the scraper 43 removes the burrs from these uneven edges of the metal ingot 200, the vertical distance between the scraper 43 and the metal ingot 200 needs to be adjusted adaptively to avoid the scraper 43 being broken. When the vertical distance between the scraper 43 and the metal ingot 200 needs to be increased, the scraper holder 42 rotates counterclockwise around the first rotating axis 411 (e.g., Figure 8 The second elastic seat 47 rotates around the second rotating shaft 423, causing the limiting rod 45 to rotate and extend upward. The spring 46 is compressed, and the first elastic seat 44 rotates around the third rotating shaft 441, so that the scraper 43 adapts to the unevenness of the metal ingot 200.

[0051] Furthermore, a positioning wheel 300 is rotatably mounted on the inner side of the scraper holder 42, and the positioning wheel 300 contacts the upper surface of the metal ingot 200. During the process of the power assembly 31 driving the scraping mechanism 4 to scrape the burrs on the metal ingot, the positioning wheel 300 always moves on the upper surface of the metal ingot 200, ensuring that the vertical distance between the scraper 43 on the scraper holder 42 and the metal ingot 200 is always maintained within a certain range. This prevents the vertical distance between the scraper 43 and the metal ingot 200 from being too large or too small, thereby improving the scraping effect on the edges and burrs of the metal ingot 200.

[0052] The steps for cleaning burrs on the edges of metal ingots using this device are as follows:

[0053] The proximity switch sensor on the support body of the conveyor detects the metal ingot 200 on the conveyor chain 100. The second telescopic member 51 drives the first positioning plate 52 at its upper end to move upward. After moving a certain height, the limiting plate 53 at the upper end of the first positioning plate 52 contacts the side of the metal ingot 200 and stops it on the conveyor chain 100. After it is perpendicular to the conveyor chain 100, the second telescopic member 51 retracts. At this time, the metal ingot 200 continues to move a certain distance on the conveyor chain 100. The first telescopic member 21 drives the ingot support plate 22 to lift the metal ingot 200 on the conveyor chain 100, and the clamping member 23 clamps the metal ingot 200. The first telescopic member 21 moves the upper surface of the metal ingot 22 to contact the lower surface of the second positioning plate 32, and the subsequent scraping work on the metal ingot 200 can begin.

[0054] The power unit 31 drives the scraper 43 at the lower end of the fixed support 41 to move and clean the burrs on the edges of the metal ingot 200. The positioning wheel 300 on the scraper seat 42 always moves on the upper surface of the metal ingot 200. When it encounters uneven areas on the edges of the metal ingot 200, the positioning wheel 300 will adapt to these positions, thereby allowing the scraper seat 42 to rotate around the first rotating shaft 411. During this process, the second elastic seat 47 rotates around the second rotating shaft 423, driving the limit rod 45 to rotate and extend upward, compressing the spring 46, and the first elastic seat 44... The scraper 43 rotates around the third pivot 441, allowing it to adapt to the uneven surfaces of the metal ingot 200. On the flat surfaces of the metal ingot 200, the spring force of the spring 46 drives the limit rod 45, the first elastic seat 44, the second elastic seat 47, and the scraper seat 42 to reset. The positioning wheel 300 always contacts the upper surface of the metal ingot 200, preventing the vertical distance between the scraper 43 and the metal ingot 200 from being too small. The power component 31 drives the scraping mechanism 4 to reciprocate once to complete the cleaning of the burrs on the edges of the metal ingot 100, thus improving the cleaning efficiency.

Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
