Description
Technical Field
[0001] This utility model relates to the field of bolt processing technology, specifically to a high-efficiency bolt thread rolling device. Background Technology
[0002] Bolts are a common type of fastener. They connect two or more components to form a complete system or machine. For example, in the construction and machinery industries, bolts are commonly used to connect bridges, building structures, vehicles, and machines. The main function of a bolt is fastening; it securely fixes two components together by rotating the nut, ensuring the stability and safety of the system or machine. In bolt manufacturing, thread rolling is particularly important, and it is generally done using a thread rolling machine. A thread rolling machine is a multi-functional cold extrusion forming machine tool. It can perform thread rolling, straight knurling, and oblique knurling on workpieces in a cold state within its rolling pressure range. Currently, during the processing, workers stand next to the thread rolling machine and hold the bolt with both hands to roll the threads. This manual operation makes the entire process more time-consuming and labor-intensive. Because workers hold the bolt with both hands, the bolt is easily affected by slight vibrations and the accuracy of visual inspection, which cannot ensure the accuracy of the thread rolling. Deflection can easily lead to poor processing results.
[0003] According to Chinese Patent CN202420457746.4, a bolt thread rolling device is disclosed. This application includes a worktable, support columns, a thread rolling structure, a sliding groove, a moving structure, and a clamping structure. Several support columns are vertically arranged at the lower end of the worktable, and the thread rolling structure for bolt thread rolling is symmetrically arranged at the upper end of the worktable. A sliding groove is formed at the upper end of the worktable. A moving structure is arranged inside the worktable and at the lower end of the sliding groove to drive the thread rolling structure. A clamping structure cooperating with the thread rolling structure is arranged on one side above the worktable. The thread rolling structure includes a support plate, a thread rolling wheel, a thread rolling shaft, and a first drive motor. The support plate has a U-shaped structure, and the thread rolling wheel is rotatably arranged at the upper end of the support plate. This allows for the insertion and removal of the clamped structure before and after processing, improving safety performance. Furthermore, the thread rolling wheel can move to process bolts of different specifications. Existing bolt thread rolling devices have limited functionality. After the bolt thread rolling process is completed, burrs will remain on the outer wall of the bolt, which need to be removed manually. This is time-consuming and affects the overall processing efficiency of the bolt.

The side of the vertical plate 2 away from the three-jaw chuck 3 is provided with a second drive motor 15. The driving end of the second drive motor 15 passes through the vertical plate 2 and is connected to the three-jaw chuck 3. The connecting assembly includes symmetrically arranged slots 26 at the bottom of the mounting post 13, and a plug-in post 27 extending into the slot 26 at the top of the arc-shaped burr scraper 14.

The take-up roller 24 pulls the take-up connecting line 25, which in turn pulls the slider 23 to move closer to the take-up roller 24. The slider 23 then moves the limiting rod 28 away from the limiting groove on the insertion post 27. At this time, the spring 29 is in a stretched state. Then, the operator pulls the arc-shaped burr scraper 14 downwards and inserts the insertion post 27 on the new arc-shaped burr scraper 14 into the slot 26. The knob 32 is then released, and the spring 29 returns to its original position, moving the slider 23 away from the take-up roller 24. The slider 23 then moves the limiting rod 28 into the limiting groove on the insertion post 27 to fix the new arc-shaped burr scraper 14. By setting up the connecting component, it is easy to disassemble and replace the arc-shaped burr scraper, reducing the disassembly and assembly time and further improving the bolt processing efficiency.
[0031] In practical applications, when performing thread rolling on bolts, one end of the bolt is fixed by a three-jaw chuck 3. Then, cylinder 10 is activated to move slider 5. Two sets of sliders 5 drive two sets of thread rolling wheels 7 to move close together and contact the outer wall of the bolt. Next, drive motor 8 is activated to rotate the thread rolling wheels 7 to perform thread rolling on the bolt. The generated waste chips enter the waste collection box 12 through the waste collection port 11 for unified processing. After the bolt thread rolling is completed, servo motor 21 is activated to rotate the lead screw 18. The lead screw 18 drives the moving block 19 downwards. The moving block 19, through mounting post 13, drives the arc-shaped burr scraper 14 downwards to contact the outer wall of the bolt. Then, drive motor 15 is activated to rotate the three-jaw chuck 3, which in turn rotates the bolt. As the bolt rotates, it rubs against the arc-shaped burr scraper 14, removing the waste chips. By setting up the mounting post, height adjustment component, and arc-shaped burr scraper, the outer wall of the bolt can be quickly deburred after the thread rolling is completed. No need for personnel to remove it from the thread rolling equipment for separate cleaning, saving time and effort and improving the overall bolt processing efficiency; when it is necessary to replace the arc-shaped burr scraper 14, the operator turns the knob 32 to drive the take-up roller 24 to rotate, the take-up roller 24 pulls the take-up connecting line 25, the connecting line 25 pulls the slider 23 to move closer to the take-up roller 24, the slider 23 drives the limit rod 28 to disengage from the limit groove on the plug post 27, at this time the spring 29 is in a stretched state, and then the operator pulls down the arc-shaped burr scraper. The new arc-shaped burr scraper 14 can be used. Insert the insertion post 27 on the new arc-shaped burr scraper 14 into the slot 26, and loosen the knob 32. At this time, the spring 29 returns to its original position, causing the slider 23 to move away from the take-up roller 24. The slider 23 drives the limit rod 28 to insert into the limit groove on the insertion post 27 to fix the new arc-shaped burr scraper 14. By setting the connecting component, it is easy to disassemble and replace the arc-shaped burr scraper, reduce the disassembly and assembly time of the arc-shaped burr scraper, and further improve the bolt processing efficiency.
[0032] In summary, by utilizing the above-mentioned technical solution of this utility model, after the bolt thread rolling process is completed, the outer wall of the bolt can be quickly deburred by setting up the mounting column, height adjustment component and arc-shaped burr scraper, without the need for personnel to remove it from the thread rolling equipment for separate cleaning, saving time and effort and improving the overall bolt processing efficiency.
