Abstract
Description
Technical Field
[0001] This utility model relates to the field of spraying device technology, specifically a spraying device for coating a soft-cutting roller of cemented carbide. Background Technology
[0002] With the continuous improvement of gear manufacturing technology, especially for small-sized, low-module hobs, there is a growing trend to switch from high-speed steel as the main material to carbide cemented carbide as the main material. The hardness and wear resistance of these tools far exceed those of ordinary high-speed steel tools and powder metallurgy high-speed steel tools.
[0003] In the production process of carbide soft-cutting hobs, coating treatment is a crucial step. Traditional spraying equipment has significant shortcomings when adapting to hobs of different lengths. Due to the variety of hob lengths, a fixed spraying range often cannot ensure that every part of the hob surface receives a uniform coating. Furthermore, it is inconvenient to adjust the spraying range according to the hob length, which can easily lead to material waste. In addition, the material is usually stored inside the material shell, and due to the lack of an effective stirring and scraping mechanism, the material is prone to sedimentation, layering, or even clumping, affecting the spraying effect. Therefore, this utility model provides a spraying device for coating carbide soft-cutting hobs. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a spraying device for coating soft-cut carbide rollers. It solves the significant deficiencies of traditional spraying devices when adapting to rollers of varying lengths. Due to the diverse lengths of the rollers, a fixed spraying range often fails to ensure a uniform coating on every part of the roller surface. Furthermore, during spraying, it is inconvenient to adjust the spraying range according to the length of the roller, easily leading to material waste. Additionally, the material is typically stored inside the material shell; the lack of an effective stirring and scraping mechanism causes the material to easily settle, separate, or even clump, affecting the spraying effect.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a spraying device for coating a carbide soft-cutting hob, comprising a spraying housing, wherein the spraying housing is provided with a spraying mechanism for coating a carbide soft-cutting hob, the spraying mechanism comprising:
[0006] The mounting assembly includes a slide rod that is slidably connected through the side wall of the sprayed housing. The upper end face of the slide rod is provided with a threaded assembly for driving. One end of the slide rod is provided with a second mounting bracket that is rotatably connected via a rotating shaft. The interior of the second mounting bracket is provided with a clamping assembly for fixing the hob. The other side wall of the sprayed housing is provided with a first mounting bracket connected via a driving assembly.
[0007] A spraying assembly includes a spraying housing fixed to the rear side wall inside the spraying housing, a nozzle fixed to the output end of the spraying housing, a sealing rod connected by a guide assembly inside the spraying housing, a support plate fixed to the rear side wall of the spraying housing, a material shell fixed to the upper end of the support plate, and a stirring assembly to prevent accumulation inside the material shell.
[0008] Preferably, the threaded assembly includes a slide rail bracket fixedly connected to the right side wall of the sprayed housing, a threaded rod rotatably connected inside the slide rail bracket, a slider slidably connected to the inner wall of the slide rail bracket, the slider being threadedly connected to the threaded rod, and the lower end of the slider being fixedly connected to the slide rod.
[0009] Preferably, the clamping assembly includes a groove formed in the inner wall of the second mounting bracket, a bidirectional screw is rotatably connected inside the groove, a clamping plate is slidably connected inside the groove, and the clamping plate is threadedly connected to the bidirectional screw.
[0010] Preferably, the drive assembly includes a support shaft rotatably connected to the left side of the sprayed housing, and the first mounting bracket is fixedly connected to one end of the support shaft.
[0011] Preferably, the guide assembly includes a guide rod fixedly connected to the side wall of the slide bar, a sealing rod fixedly connected to the other end of the guide rod, and the sealing rod being slidably connected to the spraying housing.
[0012] Preferably, the stirring assembly includes a drive shaft rotatably connected inside the material shell, a stirring rod fixedly connected to the outer wall of the drive shaft, an L-shaped scraper bracket fixed to the upper outer wall of the drive shaft, and a guide pipe penetrating the lower end of the material shell, one end of the guide pipe being in a flow connection with the spray coating shell.
[0013] Beneficial effects
[0014] This invention provides a spraying device for coating soft-cutting rollers of cemented carbide. Compared with the prior art, it has the following advantages:
[0015] Firstly, this utility model utilizes a rotating threaded rod to allow a slider to slide within a slide rail bracket. This, in turn, causes a sliding rod at the lower end of the slider to slide on the side wall of the spraying housing. This allows for adjustment based on the length of the carbide soft-cutting roller, enabling the device to accommodate rollers of varying lengths and improving its versatility and flexibility. The sliding rod, secured by a guide rod, slides within the spraying housing, synchronously adjusting the nozzle's spraying range according to the roller's length. This ensures that every part of the roller's surface receives a uniform coating, matching the nozzle's spraying range to the roller's length and preventing waste during spraying.
[0016] Secondly, this utility model utilizes the rotation of a bidirectional screw to cause the clamping plate to open and close along the interior of the slide groove, thereby clamping the roller cutter. The other end of the roller cutter is then fixed by a first mounting bracket, which rotates under the action of a motor via a support shaft, thus rotating the roller cutter. This rotation allows the coating material to be evenly covered on the roller cutter surface during spraying. The rotation process reduces manual intervention and lowers the labor intensity of workers. Furthermore, by adjusting the opening and closing degree of the clamping plate, the device can accommodate roller cutters of different sizes, improving the versatility and flexibility of the equipment. The stirring rod on the outer wall of the drive shaft stirs the material inside the material shell, ensuring uniform mixing of the coating material and preventing spraying quality problems caused by material sedimentation or stratification. It effectively prevents material agglomeration and ensures that the material maintains its fluidity during storage and transportation, allowing it to smoothly enter the spraying shell through the guide pipe. The scraper bracket rotates along the inner wall of the material shell, scraping off the material adhering to the inner wall, avoiding material waste and improving material utilization.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a spraying device for coating a carbide soft-cutting roller, comprising a spraying housing 1, on which a spraying mechanism for coating a carbide soft-cutting roller is provided, the spraying mechanism comprising:
[0025] The mounting assembly includes a slide rod 3 that is slidably connected through the side wall of the sprayed housing 1. The upper end face of the slide rod 3 is provided with a threaded assembly for driving. One end of the slide rod 3 is provided with a second mounting bracket 4 that is rotatably connected via a rotating shaft. The interior of the second mounting bracket 4 is provided with a clamping assembly for fixing the hob. The other side wall of the sprayed housing 1 is provided with a first mounting bracket 201 that is connected via a driving assembly.
[0026] The spraying assembly includes a spraying housing 5 fixed to the rear wall inside the spraying housing 1, a nozzle 501 fixed to the output end of the spraying housing 5, a sealing rod 502 connected by a guide assembly inside the spraying housing 5, a support plate 6 fixed to the rear wall of the spraying housing 1, a material housing 601 fixed to the upper end of the support plate 6, and a stirring assembly to prevent accumulation inside the material housing 601.
[0027] In a preferred embodiment, the threaded assembly includes a slide rail bracket 301 fixedly connected to the right side wall of the sprayed housing 1. A threaded rod 303 is rotatably connected inside the slide rail bracket 301, and a slider 302 is slidably connected to the inner wall of the slide rail bracket 301. The slider 302 is threadedly connected to the threaded rod 303, and the lower end of the slider 302 is fixedly connected to the slide rod 3. By rotating the threaded rod 303, the slider 302 slides inside the slide rail bracket 301 through the threaded rod 303, causing the slide rod 3 at the lower end of the slider 302 to slide on the side wall of the sprayed housing 1. This allows for adjustment according to the length of the carbide soft cutting cutter, enabling the device to adapt to cutters of different lengths and improving the versatility and flexibility of the equipment.
[0028] In a preferred embodiment, the clamping assembly includes a groove 401 formed in the inner wall of the second mounting bracket 4. A bidirectional screw 403 is rotatably connected inside the groove 401, and a clamping plate 402 is slidably connected inside the groove 401. The clamping plate 402 is threadedly connected to the bidirectional screw 403. The driving assembly includes a support shaft 2 rotatably connected inside the left side of the spray shell 1. The first mounting bracket 201 is fixedly connected to one end of the support shaft 2. By rotating the bidirectional screw 403, the clamping plate 402 moves along the inside of the groove 401 via the bidirectional screw 403. The device opens and closes to clamp the roller cutter, and then the other end of the roller cutter is fixed by the first mounting bracket 201. The first mounting bracket 201 rotates under the action of the motor via the support shaft 2, thereby rotating the roller cutter. This rotation allows the spraying material to be evenly covered on the surface of the roller cutter. The rotation process reduces manual intervention and the labor intensity of the workers. Furthermore, by adjusting the opening and closing degree of the clamping plate 402, the device can adapt to roller cutters of different sizes, improving the versatility and flexibility of the equipment.
[0029] In a preferred embodiment, the guide assembly includes a guide rod 503 fixedly connected to the side wall of the slide rod 3, and a sealing rod 502 fixedly connected to the other end of the guide rod 503. The sealing rod 502 is slidably connected to the spraying housing 5. When adjusting the slide rod 3 according to the length of the roller cutter, the side wall of the slide rod 3 slides inside the spraying housing 5 through the sealing rod 502 fixed by the guide rod 503, thereby synchronously adjusting the spraying range of the nozzle 501 according to the length of the roller cutter. This ensures that every part of the roller cutter surface receives a uniform coating, and the spraying range of the nozzle 501 matches the length of the roller cutter, avoiding waste during spraying.
[0030] In a preferred embodiment, the mixing assembly includes a drive shaft 602 rotatably connected inside the material shell 601. A stirring rod 603 is fixedly connected to the outer wall of the drive shaft 602. An L-shaped scraper bracket 604 is fixed to the upper outer wall of the drive shaft 602. A guide pipe 504 is connected through the lower end of the material shell 601. One end of the guide pipe 504 is in a flow connection with the spraying housing 5. The material shell 601 is used to store the raw material for rotary blade spraying. The raw material is then pumped through the guide pipe 504 into the interior of the spraying housing 5 for spraying. The drive shaft 602 is driven by a motor, which drives the stirring rod 603 on the outer wall of the drive shaft 602 to stir inside the material shell 601. This ensures uniform mixing of the coating material, prevents coating quality problems caused by material sedimentation or stratification, effectively prevents material agglomeration, and ensures that the material maintains its fluidity during storage and transportation. This allows it to smoothly pass through the guide pipe 504 into the coating shell 5. The scraper bracket 604 rotates along the inner wall of the material shell 601, which can scrape off the material adhering to the inner wall, avoiding material waste and improving material utilization.
[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0032] During operation, the rotation of the bidirectional screw 403 causes the clamping plate 402 to open and close along the inside of the slide groove 401 via the bidirectional screw 403, thereby clamping the hob. Then, the other end of the hob is fixed by the first mounting bracket 201. The first mounting bracket 201 then rotates under the action of the motor via the support shaft 2, thereby rotating the hob. This rotation allows the spraying material to be evenly covered on the surface of the hob. The rotation process reduces manual intervention. Then, by rotating the threaded rod 303, the slider 302 slides inside the slide rail bracket 301 via the threaded rod 303, causing the slide rod 3 at the lower end of the slider 302 to slide on the side wall of the spraying housing 1, thereby adjusting the length according to the length of the carbide soft cutting hob.
[0033] The material housing 601 is used to store the raw materials for roller coating. The raw materials are then pumped into the coating housing 5 through the feed pipe 504 by a pump. The drive shaft 602 is driven by a motor, which drives the stirring rod 603 on the outer wall of the drive shaft 602 to stir inside the material housing 601. This ensures uniform mixing of the coating materials. When the slide rod 3 is adjusted according to the length of the roller, the sealing rod 502 fixed by the guide rod 503 slides inside the coating housing 5, thereby synchronously adjusting the spraying range of the nozzle 501 according to the length of the roller. This ensures that every part of the roller surface receives a uniform coating.
