Description

Technical Field

[0001] This invention belongs to the technical field of bolt production equipment, specifically a bolt production equipment with a grinding structure and its usage method. Background Technology

[0002] A bolt is a cylindrical threaded fastener that is fitted with a nut. It consists of two parts: a head and a shank (a cylinder with external threads).

[0003] Bolt production equipment is a type of mechanical equipment used to manufacture bolts, encompassing multiple production stages from raw material processing to finished bolts.

[0004] A search revealed a patent, CN215033264U, for example, a forming device for producing cold-forged bolt components for high-speed rail. The device includes a machine body; a base is located at the bottom of the machine body, and multiple damping springs are arranged between the machine body and the base. A gantry frame is located at the top of the machine body, and multiple first telescopic rods are located at the top of the gantry frame. A pressure plate is located at the bottom of the first telescopic rods, and multiple punching heads are located at the bottom of the pressure plate. A holding groove is located on the upper side of the machine body directly below the punching heads, and a top plate is located inside the holding groove. A top rod is located at the bottom of the top plate, extending into the machine body. A second telescopic rod is located at the bottom of the top rod, and both ends of the second telescopic rod are fixedly installed at the bottom of the top rod and the bottom of the machine body by bolts. During processing, the damping springs between the machine body and the base can buffer the vibration generated by the machine body, reducing the vibration amplitude and preventing large vibration amplitudes from affecting the processing effect on the workpiece.

[0005] Current bolt manufacturing systems undoubtedly excel in improving production efficiency. However, during the bolt manufacturing process, burrs may appear on the surface of the bolts due to factors such as process, equipment, or materials. The presence of these burrs not only affects the appearance quality of the bolts but may also adversely affect their performance. Therefore, in order to ensure the quality and performance of the bolts, a grinding process needs to be added to the production process. Specialized grinding equipment is used to perform meticulous grinding on the bolts to further improve the overall quality of the bolts. Summary of the Invention

[0006] The purpose of this invention is to provide a bolt production apparatus with a grinding structure and a method for using it, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a bolt production device with a grinding structure, comprising a production device body, a grinding box being provided at one end of the production device body, and a grinding assembly being provided inside the grinding box;

[0008] The grinding assembly includes a grinding roller disposed inside the grinding chamber. One end of the grinding roller is fitted with a protective cover by connecting bolts, and the other end of the grinding roller is fixedly connected to a first rotating shaft. One end of the first rotating shaft is fitted with a first motor, which is disposed on the inner wall of the grinding chamber.

[0009] As a further technical solution of the present invention, the inner wall of the grinding roller is provided with a second through hole, and the second through hole is uniformly arranged in a ring array.

[0010] As a further technical solution of the present invention, the grinding roller has a third through hole inside, and there are multiple third through holes. Each third through hole has a baffle embedded in its inner wall. Each baffle is fixedly connected by a connecting plate. A magnetic block is fixedly connected to one end of the connecting plate. An electromagnet is provided at the end of the magnetic block away from the connecting plate. The electromagnet is installed inside the grinding roller.

[0011] As a further technical solution of the present invention, the magnetic block is slidably installed inside the grinding drum, and a tension spring is connected between the magnetic block and the grinding drum.

[0012] As a further technical solution of the present invention, a collection box is provided below the grinding roller. The collection box is slidably installed inside the grinding box. The inside of the collection box is evenly provided with first through holes. A toggle component is provided above the collection box. A scraper is fixedly connected to the bottom of the collection box. Two scrapers are symmetrically arranged.

[0013] As a further technical solution of the present invention, the actuating assembly includes a movable rod disposed above the collection box. Multiple third rotating shafts are embedded inside the movable rod. A fixing plate is fixedly installed at one end of each third rotating shaft. A lever is fixedly installed at both ends of the fixing plate. Second rotating shafts are fixedly connected to both ends of the movable rod. A slider is rotatably connected to the ends of two second rotating shafts away from the movable rod. Both sliders are slidably mounted on the inner wall of the grinding chamber. A threaded rod is threadedly connected inside one of the sliders, and a second motor is installed at one end of the threaded rod.

[0014] As a further technical solution of the present invention, the third rotating shaft is rotatably mounted on the inner wall of the moving rod, and a torsion spring is mounted on the outer wall of the third rotating shaft.

[0015] As a further technical solution of the present invention, a gear is fixedly installed on the outer wall of the second rotating shaft, and a rack plate is meshed with the bottom end of the gear. The rack plate is fixedly installed on the inner wall of the grinding box.

[0016] As a further technical solution of the present invention, a protrusion is slidably installed inside the movable rod, and a spring is installed between the protrusion and the movable rod.

[0017] A method of using a bolt production apparatus with a grinding structure includes the following steps:

[0018] S1: When the bolts need to be ground during the bolt production process, first put the bolts and grinding balls into the grinding drum, then install the protective cover on one end of the grinding drum by connecting bolts, and then start the first motor. When the first motor starts, it drives the first rotating shaft to rotate. The rotation of the first rotating shaft drives the rotation of the grinding drum, so that the bolts and grinding balls rotate inside the grinding drum and the bolts are ground by the grinding balls.

[0019] S2: During the bolt grinding process, the burrs and iron powder that are ground off the bolt surface are discharged into the grinding roller through the second through hole.

[0020] S3: When the grinding balls need to be separated from the bolts after grinding, the electromagnet is activated to generate a magnetic force, causing the magnetic block to move to one side of the electromagnet. The movement of the magnetic block drives the movement of the connecting plate, and the movement of the connecting plate drives the movement of the baffle to open the third through hole, so that the grinding balls in the grinding roller are discharged from the third through hole.

[0021] S4: After the grinding balls are discharged from the grinding drum, they fall into the collection box and are collected.

[0022] S5: When discharging grinding balls, the second motor is started at the same time. The start of the second motor drives the rotation of the threaded rod. The rotation of the threaded rod drives the slider to move back and forth inside the grinding box. The movement of the slider drives the movement of the second rotating shaft. The movement of the second rotating shaft drives the movement of the moving rod. The movement of the moving rod drives the fixed plate and the lever to move back and forth inside the collection box, agitating the grinding balls inside the collection box.

[0023] S6: When the moving rod moves back and forth under the grinding cylinder, the movement of the moving rod drives the movement of the protrusion. When the protrusion contacts the bottom end of the grinding cylinder, the elastic potential energy of the spring causes the protrusion to move up and down back and forth to strike the surface of the grinding cylinder.

[0024] S7: The movement of the second rotating shaft drives the movement of the gear. When the gear moves and meshes with the rack plate, it rotates. The rotation of the gear drives the rotation of the second rotating shaft. The rotation of the second rotating shaft drives the rotation of the moving rod, causing the moving rod to drive the fixed plate and the lever to rotate, parallel to the collection box. After processing, the collection box is taken out.

[0025] S8: Finally, turn off the first motor, the second motor and the electromagnet, remove the protective cover from one end of the grinding roller and take out the ground bolts inside the grinding roller.

[0026] The beneficial effects of this invention are as follows:

[0027] 1. This invention, through the setting of a grinding component, allows for the grinding of bolts during the bolt production process. First, the bolt and grinding balls are placed into the grinding drum. Then, a protective cover is installed at one end of the grinding drum using connecting bolts. Next, the first motor is started, driving the first rotating shaft to rotate. The rotation of the first rotating shaft drives the grinding drum to rotate, causing the bolt and grinding balls to rotate inside the grinding drum. The grinding balls then grind the bolt. By adding a grinding step to the production process, the bolt production quality is improved.

[0028] 2. This invention utilizes the cooperation of an electromagnet and a magnetic block. When it is necessary to separate the grinding balls from the bolt after grinding, the electromagnet is activated to generate an attractive force on the magnetic block, causing the magnetic block to move towards one side of the electromagnet. The movement of the magnetic block drives the movement of the connecting plate, which in turn drives the movement of the baffle to open the third through hole. The grinding balls inside the grinding roller are then discharged from the third through hole. At the same time, the grinding roller can continue to rotate, which helps to separate the grinding balls from the ground bolt, making it easy to remove the ground bolt directly.

[0029] 3. By setting up the agitator component, the second motor is started simultaneously when the grinding balls are discharged. The start of the second motor drives the rotation of the threaded rod, which in turn drives the slider to reciprocate inside the grinding box. The movement of the slider drives the movement of the second rotating shaft, which in turn drives the movement of the moving rod. The movement of the moving rod drives the fixed plate and the agitator to reciprocate inside the collection box, agitating the grinding balls inside the collection box. This helps to separate the grinding balls from burrs and iron powder, facilitating subsequent recycling. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] like Figures 1 to 7 As shown in the embodiment of the present invention, a bolt production device with a grinding structure includes a production device body 1, a grinding box 2 is provided at one end of the production device body 1, and a grinding component is provided inside the grinding box 2.

[0040] The grinding assembly includes a grinding roller 3 disposed inside the grinding box 2. One end of the grinding roller 3 is fitted with a protective cover 8 by connecting bolts 4, and the other end of the grinding roller 3 is fixedly connected to a first rotating shaft 5. One end of the first rotating shaft 5 is fitted with a first motor 6, which is disposed on the inner wall of the grinding box 2.

[0041] When bolts need to be ground during the production process, the bolts and grinding balls are first placed into the grinding roller 3. Then, the protective cover 8 is installed at one end of the grinding roller 3 by connecting bolts 4. The first motor 6 is then started. When the first motor 6 starts, it drives the first rotating shaft 5 to rotate. The rotation of the first rotating shaft 5 drives the grinding roller 3 to rotate, so that the bolts and grinding balls rotate inside the grinding roller 3. The bolts are ground by the grinding balls. Adding a grinding step to the production process to grind the bolts improves the production quality of the bolts.

[0042] The existing patent CN215033264U discloses a forming device for producing cold-forged bolt components for high-speed rail. This patent discloses a machine body 1. The main body 1 of the production device in this application adopts the same technical means as this prior art, which will not be described in detail here.

[0043] like Figures 1 to 7 As shown, the inner wall of the grinding roller 3 is provided with a second through hole 11, and the second through holes 11 are evenly arranged in a ring array.

[0044] During the bolt grinding process, the burrs and iron powder that are ground off the bolt surface are discharged into the grinding roller 3 through the second through hole 11. This prevents the burrs and iron powder from remaining in contact with the bolt inside the grinding roller 3 and easily entering the bolt thread, which would affect the bolt processing quality. Timely discharge of burrs and iron powder helps to improve the bolt processing quality.

[0045] like Figure 6 and Figure 7 As shown, the grinding roller 3 has a third through hole 12 inside. There are multiple third through holes 12. Each third through hole 12 has a baffle 13 embedded in its inner wall. Each baffle 13 is fixedly connected by a connecting plate 14. A magnetic block 29 is fixedly connected to one end of the connecting plate 14. An electromagnet 16 is provided at the end of the magnetic block 29 away from the connecting plate 14. The electromagnet 16 is installed inside the grinding roller 3.

[0046] When the grinding balls need to be separated from the bolt after grinding, the electromagnet 16 is activated to generate an attractive force on the magnetic block 29, causing the magnetic block 29 to move to one side of the electromagnet 16. The movement of the magnetic block 29 drives the movement of the connecting plate 14, which in turn drives the baffle 13 to move and open the third through hole 12. The grinding balls in the grinding roller 3 are discharged from the third through hole 12. At the same time, the grinding roller 3 can continue to rotate, which helps to separate the grinding balls from the ground bolt, making it easy to remove the ground bolt directly.

[0047] like Figure 7 As shown, the magnetic block 29 is slidably installed inside the grinding roller 3, and a tension spring 15 connects the magnetic block 29 and the grinding roller 3.

[0048] When the magnetic block 29 moves to one side of the electromagnet 16, the tension spring 15 deforms under force and stores elastic potential energy. After the grinding balls are discharged, the electromagnet 16 is turned off, and the elastic potential energy is released through the tension spring 15 to drive the magnetic block 29 to reset, thereby moving the baffle 13 to below the third through hole 12, which facilitates the normal use of the subsequent grinding roller 3.

[0049] like Figure 2 and Figure 3 As shown, a collection box 7 is provided below the grinding roller 3. The collection box 7 is slidably installed inside the grinding box 2. The inside of the collection box 7 is evenly provided with first through holes 9. A toggle assembly is provided above the collection box 7. A scraper 10 is fixedly connected to the bottom of the collection box 7. Two scrapers 10 are symmetrically arranged.

[0050] After the grinding balls are discharged from the grinding drum 3, they fall into the collection box 7 for collection. At this time, the burrs and iron powder that are ground off the bolt surface can continue to be discharged downward through the first through hole 9, which makes it easy to separate the grinding balls from the burrs and iron powder, thus facilitating the recycling of the grinding balls.

[0051] When the collection box 7 needs to be removed, the movement of the collection box 7 drives the scraper 10 to move. When the scraper 10 moves, it scrapes the iron powder under the collection box 7 outward, which makes it easier to clean the burrs and iron powder that are ground off the surface of the bolt.

[0052] like Figures 3 to 5 As shown, the actuation assembly includes a movable rod 30 positioned above the collection box 7. Multiple third rotating shafts 19 are embedded inside the movable rod 30. A fixed plate 21 is fixedly installed at one end of each third rotating shaft 19. A lever 22 is fixedly installed at both ends of the fixed plate 21. A second rotating shaft 18 is fixedly connected to both ends of the movable rod 30. A slider 17 is rotatably connected to the end of each of the two second rotating shafts 18 away from the movable rod 30. Both sliders 17 are slidably installed on the inner wall of the grinding box 2. A threaded rod 27 is threadedly connected inside one of the sliders 17. A second motor 28 is installed at one end of the threaded rod 27.

[0053] When discharging the grinding balls, the second motor 28 is started simultaneously. The start of the second motor 28 drives the rotation of the threaded rod 27. The rotation of the threaded rod 27 causes the slider 17 to move back and forth inside the grinding box 2. The movement of the slider 17 drives the movement of the second rotating shaft 18. The movement of the second rotating shaft 18 drives the movement of the moving rod 30. The movement of the moving rod 30 causes the fixed plate 21 and the lever 22 to move back and forth inside the collection box 7, agitating the grinding balls inside the collection box 7. This helps to separate the grinding balls, burrs, and iron powder inside the collection box 7, facilitating subsequent recycling.

[0054] like Figure 4 As shown, the third rotating shaft 19 is rotatably mounted on the inner wall of the moving rod 30, and a torsion spring 20 is mounted on the outer wall of the third rotating shaft 19.

[0055] When the lever 22 moves inside the collection box 7, it rotates around the third rotating shaft 19 when it comes into contact with the grinding balls. When the third rotating shaft 19 rotates, the torsion spring 20 deforms and stores elastic potential energy. The elastic potential energy is released through the torsion spring 20, causing the third rotating shaft 19 to reverse and reset. This causes the lever 22 to rotate back and forth, actuating the grinding balls inside the collection box 7, further improving the separation effect of the grinding balls and burr iron powder.

[0056] like Figures 1 to 7 As shown, a gear 25 is fixedly installed on the outer wall of one of the second rotating shafts 18, and a rack plate 26 is meshed with the bottom end of the gear 25. The rack plate 26 is fixedly installed on the inner wall of the grinding box 2.

[0057] The movement of the second rotating shaft 18 drives the movement of the gear 25. When the gear 25 moves and meshes with the rack plate 26, it rotates. The rotation of the gear 25 drives the rotation of the second rotating shaft 18. The rotation of the second rotating shaft 18 drives the rotation of the moving rod 30, so that the moving rod 30 drives the fixed plate 21 and the lever 22 to rotate, which are parallel to the collection box 7, making it easy to remove the collection box 7 after processing.

[0058] like Figure 4 As shown, a protrusion 23 is slidably mounted inside the movable rod 30, and a spring 24 is installed between the protrusion 23 and the movable rod 30.

[0059] When the moving rod 30 moves back and forth below the grinding roller 3, the movement of the moving rod 30 drives the movement of the protrusion 23. When the protrusion 23 contacts the bottom end of the grinding roller 3, the elastic potential energy of the spring 24 causes the protrusion 23 to move up and down back and forth to strike the surface of the grinding roller 3, which helps to remove the sand balls and burr iron powder inside the grinding roller 3.

[0060] A method of using a bolt production apparatus with a grinding structure includes the following steps:

[0061] S1: When the bolts need to be ground during the bolt production process, first put the bolts and grinding balls into the grinding roller 3, then install the protective cover 8 at one end of the grinding roller 3 through the connecting bolts 4, and then start the first motor 6. When the first motor 6 starts, it drives the first rotating shaft 5 to rotate. The rotation of the first rotating shaft 5 drives the rotation of the grinding roller 3, so that the bolts and grinding balls rotate inside the grinding roller 3, and the bolts are ground by the grinding balls.

[0062] S2: During the bolt grinding process, the burrs and iron powder that are ground off the bolt surface are discharged into the grinding roller 3 through the second through hole 11.

[0063] S3: When the grinding balls need to be separated from the bolts after grinding, the electromagnet 16 is activated to generate a magnetic force on the magnetic block 29, causing the magnetic block 29 to move to one side of the electromagnet 16. The movement of the magnetic block 29 drives the movement of the connecting plate 14, and the movement of the connecting plate 14 drives the baffle 13 to move and open the third through hole 12, so that the grinding balls in the grinding roller 3 are discharged from the third through hole 12.

[0064] S4: After the abrasive balls are discharged from the grinding roller 3, they fall into the collection box 7 for collection.

[0065] S5: When discharging the grinding balls, the second motor 28 is started at the same time. The start of the second motor 28 drives the threaded rod 27 to rotate. The rotation of the threaded rod 27 drives the slider 17 to move back and forth inside the grinding box 2. The movement of the slider 17 drives the movement of the second rotating shaft 18. The movement of the second rotating shaft 18 drives the movement of the moving rod 30. The movement of the moving rod 30 drives the fixed plate 21 and the lever 22 to move back and forth inside the collection box 7, agitating the grinding balls inside the collection box 7.

[0066] S6: When the moving rod 30 moves back and forth below the grinding roller 3, the movement of the moving rod 30 drives the movement of the protrusion 23. When the protrusion 23 contacts the bottom end of the grinding roller 3, the elastic potential energy of the spring 24 causes the protrusion 23 to move up and down repeatedly to strike the surface of the grinding roller 3.

[0067] S7: The movement of the second rotating shaft 18 drives the movement of the gear 25. When the gear 25 moves and meshes with the rack plate 26, it rotates. The rotation of the gear 25 drives the rotation of the second rotating shaft 18. The rotation of the second rotating shaft 18 drives the rotation of the moving rod 30, so that the moving rod 30 drives the fixed plate 21 and the lever 22 to rotate, which are parallel to the collection box 7. After the processing is completed, the collection box 7 is taken out.

[0068] S8: Finally, turn off the first motor 6, the second motor 28 and the electromagnet 16, remove the protective cover 8 from one end of the grinding roller 3, and remove the ground bolts from the grinding roller 3.

[0069] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

S7: The movement of the second rotating shaft (18) drives the movement of the gear (25). When the gear (25) moves and meshes with the rack plate (26), it rotates. The rotation of the gear (25) drives the rotation of the second rotating shaft (18). The rotation of the second rotating shaft (18) drives the rotation of the moving rod (30), so that the moving rod (30) drives the fixed plate (21) and the lever (22) to rotate, which are parallel to the collection box (7). After the processing is completed, the collection box (7) is taken out. S8: Finally, turn off the first motor (6), the second motor (28) and the electromagnet (16), remove the protective cover (8) from one end of the grinding roller (3), and take out the ground bolts inside the grinding roller (3).
