Description

Technical Field

[0001] This utility model belongs to the technical field of twist drill production, specifically relating to a spraying device for twist drill production. Background Technology

[0002] Twist drills are commonly used drilling tools, and their performance and lifespan directly affect processing efficiency and cost. Traditional twist drills suffer from frequent friction, leading to wear on the drill tip and cutting edge, resulting in decreased cutting performance and drilling accuracy, frequent replacements, and increased costs. Applying a wear-resistant coating to twist drills can improve their wear resistance and lifespan.

[0003] A search revealed a patent in the relevant field with publication number CN212215994U, entitled "A Spraying Device for Twist Drill Production with Thread Clamping Function." While this device facilitates the collection of excess material during the spraying process, the spraying operation is not conducted in a confined space. Dust and impurities can easily mix into the coating material, leading to defects such as particles and bubbles in the coating. This reduces the adhesion between the coating and the surface of the twist drill, affecting the coating quality and the wear resistance of the twist drill. Therefore, this paper provides another spraying device for twist drill production to solve the above-mentioned technical problems. Utility Model Content

[0004] To address the problem of existing twist drill production spraying devices where dust and impurities easily adhere to the coating material during spraying, reducing coating adhesion and affecting coating quality and the wear resistance of the twist drills, this invention provides a twist drill production spraying device that employs a magnetic suspension method. Magnetic columns are used to attract and suspend the twist drills below a connecting plate. The cooperation between the carrier plate and the sealing door creates a closed space within the processing chamber. During spraying, a geared motor drives the connecting plate, causing the magnetic columns and twist drills to rotate synchronously. Simultaneously, the spray nozzle evenly sprays the outer surface of the twist drills. The entire spraying process is completed in a closed environment, effectively preventing dust and impurities from mixing into the coating, thereby improving coating quality and enhancing the wear resistance of the twist drills. This effectively solves the problem of existing twist drill production spraying devices where dust and impurities easily adhere to the coating material during spraying, reducing coating adhesion and affecting coating quality and the wear resistance of the twist drills. The specific technical solution is as follows:

[0005] A coating device for producing twist drills includes a base, a processing box fixedly mounted on the upper surface of the base, and openings extending through the top and front of the processing box. A tiltable and adjustable carrier plate is mounted at the top opening. A geared motor is fixedly mounted on the upper surface of the carrier plate, and the output end of the geared motor passes through the carrier plate and is located inside the processing box. A connecting plate is fixedly mounted on the lower surface of the output end of the geared motor. A magnetic column is detachably mounted on the lower surface of the connecting plate. A groove is formed on the lower surface of the magnetic column, and a twist drill is inserted into the groove. The inner diameter of the top and bottom of the groove is the same as the diameter of two different sizes of twist drills. A sealing door is rotatably mounted at the front opening. A coating pipe is fixedly mounted on the inner wall of the processing box, and multiple nozzles are fixedly mounted at equal intervals on the side of the coating pipe near the twist drill.

[0006] In the above technical solution, a paint pump is fixedly installed on the left surface of the processing box, a feed pipe is connected between the discharge port of the paint pump and the inlet end of the spray pipe, and a feed pipe is connected to the inlet of the paint pump.

[0007] In the above technical solution, a bolt and nut assembly is installed between the connecting plate and the magnet post.

[0008] In the above technical solution, a magnet is embedded and fixedly installed on the rear surface of the sealing door, and an iron block is embedded and fixedly installed on the front surface of the processing box. When the rear surface of the sealing door is attached to the front surface of the processing box, the magnet is attracted to the front surface of the iron block.

[0009] In the above technical solution, lugs are fixedly installed on both the left and right surfaces of the processing box, and adapter posts are fixedly installed on both the left and right surfaces of the carrier plate. The adapter posts are rotatably connected to the corresponding lugs. A hydraulic telescopic rod is rotatably installed between the lower rear surface of the carrier plate and the rear surface of the processing box. Adapter A and adapter B are rotatably installed at the upper and lower ends of the hydraulic telescopic rod, respectively. Adapter A is fixedly installed on the lower rear surface of the carrier plate, and adapter B is fixedly installed on the rear surface of the processing box.

[0010] The spraying device for producing twist drills according to this utility model has the following advantages compared with the prior art:

[0011] I. This utility model employs a magnetic suspension method, using magnetic pillars to attract and suspend the twist drill below the connecting plate. The cooperation between the carrier plate and the sealing door creates a closed space within the processing box. During spraying, a geared motor drives the connecting plate, causing the magnetic pillars and twist drill to rotate synchronously. Simultaneously, the spray nozzle evenly sprays the outer surface of the twist drill. The entire spraying process is completed in a sealed environment, effectively preventing dust and impurities from mixing into the coating, thereby improving coating quality and enhancing the wear resistance of the twist drill.

[0012] Second, this utility model fixes the grooved magnet column to the connecting plate with a bolt and nut assembly. According to the specifications of the twist drill to be sprayed, the bolt and nut assembly can be disassembled to replace the magnet column with different specifications of groove, thereby enhancing the versatility and practicality of the device.

[0013] Third, this utility model rotatably connects the carrier plate and the processing box, and rotatably installs a hydraulic telescopic rod between the lower rear surface of the carrier plate and the rear surface of the processing box. When installing and disassembling the twist drill, the hydraulic telescopic rod can be used to drive the carrier plate to flip, thereby driving the magnet column to adjust to the appropriate installation or disassembly angle of the twist drill, making the installation and disassembly between the twist drill and the magnet column more convenient and quick.

[0020] 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.

[0021] In this embodiment, front, back, left, right, top, and bottom are... Figure 1 Describe the reference plane. See [link / reference] Figures 1-5 This utility model provides a technical solution:

[0022] A spraying device for producing twist drills includes a base 1. A processing box 2 is fixedly installed on the upper surface of the base 1. The top and front end of the processing box 2 have through openings. A tiltable and adjustable carrier plate 3 is installed at the top opening. A geared motor 4 is fixedly installed on the upper surface of the carrier plate 3. The output end of the geared motor 4 passes through the carrier plate 3 and is located inside the processing box 2. A connecting plate 41 is fixedly installed on the lower surface of the output end of the geared motor 4. A magnet post 5 is detachably installed on the lower surface of the connecting plate 41. The lower surface of the magnet post 5 has a protrusion. Twist drills 6 are inserted into groove 51 and protrusion 51. The top and bottom inner diameters of protrusion 51 are the same as the diameters of two different sizes of twist drills 6. A sealing door 21 is rotatably installed at the front opening. A spray pipe 7 is fixedly installed on the inner wall of the processing box 2. Multiple nozzles 71 are fixedly installed at equal intervals on the side of the spray pipe 7 near the twist drill 6. A paint pump 8 is fixedly installed on the left surface of the processing box 2. A feed pipe 81 is connected between the discharge port of the paint pump 8 and the inlet end of the spray pipe 7. A feed pipe 82 is connected to the inlet of the paint pump 8.

[0023] Before use, connect the feed pipe 82 to the external paint source. When using, open the sealing door 21 and insert the twist drill 6 to be processed into the groove 51 of the magnetic post 5. The magnetic post 5 will attract and hold the twist drill 6 below the connecting plate 41. Then close the sealing door 21. At this time, the twist drill 6 is in a closed state in the processing box 2. Then, start the geared motor 4 and the paint pump 8. The geared motor 4 rotates at a constant speed, which drives the twist drill 6 to rotate at a constant speed through the connecting plate 41 and the magnetic post 5. The paint pump 8 supplies paint into the spray pipe 7 through the feed pipe 81 and the feed pipe 82. The paint is sprayed onto the outer surface of the twist drill 6 through the nozzle 71. During the rotation of the twist drill 6, the cutting edge is fully sprayed. The entire spraying process is carried out in the sealed processing box 2. Compared with the existing technology, it can effectively prevent the paint from being contaminated with dust or impurities during the spraying process, which can improve the coating quality and enhance the wear resistance of the twist drill 6.

[0024] Combination Figure 3 As shown, a bolt and nut assembly 411 is installed between the connecting plate 41 and the magnet post 5. The magnet post 5 can be separated from the connecting plate 41 by disassembling the bolt and nut assembly 411. When using the magnet post 5 to hold twist drills 6 of different specifications, the magnet post 5 with the corresponding specification of the protrusion 51 can be selected and installed under the connecting plate 41 for use, thereby enhancing the versatility and practicality of the device.

[0025] Combination Figure 5As shown, a magnet 211 is embedded and fixedly installed on the rear surface of the sealing door 21, and an iron block 23 is embedded and fixedly installed on the front surface of the processing box 2. When the rear surface of the sealing door 21 is in contact with the front surface of the processing box 2, the magnet 211 is attracted to the front surface of the iron block 23. When the sealing door 21 is closed, it is attracted and fixed to the front surface of the processing box 2 through the cooperation of the magnet 211 and the iron block 23.

[0026] It is worth noting that during the process of inserting the twist drill 6 into the groove 51, the operation was inconvenient due to the limited operating angle. To improve the operating angle, combined with... Figure 4 and Figure 5 As shown, lugs 22 are fixedly installed on both the left and right surfaces of the processing box 2, and adapter posts 31 are fixedly installed on both the left and right surfaces of the carrier plate 3. The adapter posts 31 are rotatably connected to the corresponding lugs 22. A hydraulic telescopic rod 9 is rotatably installed between the lower rear surface of the carrier plate 3 and the rear surface of the processing box 2. Adapter seats A91 and B92 are rotatably installed at the upper and lower ends of the hydraulic telescopic rod 9, respectively. Adapter seat A91 is fixedly installed on the lower rear surface of the carrier plate 3, and adapter seat B92 is fixedly installed on the rear surface of the processing box 2. The carrier plate 3 can be flipped by the extension and retraction of the hydraulic telescopic rod 9, thereby causing the magnet post 5 to flip and present the position of the protrusion 51 to the operator for placement of the twist drill 6. After placement, the carrier plate 3 is flipped back to its original position by the hydraulic telescopic rod 9 and placed over the top opening of the processing box 2.
