Abstract
Description
Technical Field
[0001] This utility model relates to the field of screw production technology, specifically to a forming and manufacturing device for screw production. Background Technology
[0002] Screws are a common type of fastener in hardware products. They are tools that use the inclined plane, circular rotation, and friction of an object to gradually tighten objects and machine parts. When processing and producing screws, a cold forging machine is usually used to fasten the metal parts to a certain depth, so that the head is slightly recessed into the mold to be fixed, and the shape of the metal parts is cold-forged into screws.
[0003] As disclosed in the patent announcement CN222403268U, a screw forming device for hardware processing includes a worktable, a fixed platform fixedly mounted on the top of the worktable, a drive mechanism fixedly mounted on the top of the fixed platform, and screws disposed inside the fixed platform. The beneficial effects of this utility model are as follows: the fixed mechanism secures the screws, facilitating cold forging by the forming mechanism, ensuring stable processing, preventing screw misalignment, and the rotation mechanism allows for mold replacement, improving screw forming efficiency and avoiding mold replacement.
[0004] Although the aforementioned patent has four sets of abutments, and during operation, the staff pushes the lever outward, which drives the connecting rod to move outward to the outside of the fixed compartment, further allowing the abutments to be stored inside the movable slot, one staff member cannot operate all four sets of abutments at the same time. Thus, a process that could originally be completed by one person requires two or more people to work together, directly increasing labor costs. Utility Model Content

A servo motor 8 is fixedly connected to the outside of the workbench 1 near the transmission groove 2. The output shaft of the servo motor 8 is fixedly connected to the rotating shaft 5. The bottom center of the mold plate 3 is rotatably connected to the transmission groove 2 via bearings. Several forming grooves are evenly distributed circumferentially on the upper end of the mold plate 3. 9. Fixed platform 4, which is fixedly connected to the right side of the top center of the workbench 1. Limiting mechanisms are provided on all four sides of the top of the fixed platform 4. These limiting mechanisms include four guide grooves 10 with equal arcs opened at the top of the fixed platform 4, and abutment bars 11 horizontally slidably connected inside the guide grooves 10. Dovetail grooves 12 are symmetrically opened on both sides of the inner wall of the guide grooves 10. A circular groove 13, communicating with the guide grooves 10, is opened through the middle of the fixed platform 4. Dovetail guide bars 14, which slide and cooperate with the dovetail grooves 12, are fixedly connected to both sides of the abutment bar 11 at the end away from the circular groove 13. An inclined surface is provided on the top of the abutment bar 11 near the circular groove 13. Four vertical guide frames 15 are fixedly connected to the outer side of the workbench 1 near the fixed platform 4 with equal arcs. A transverse guide rod 16 is fixedly connected to the end face of the strip 11 away from the circular groove 13. The guide rod 16 is slidably engaged with the movable hole on the guide frame 15. A spring 17 is movably sleeved on the outside of the guide rod 16. The two ends of the spring 17 abut against the guide frame 15 and the abutment strip 11, respectively. The limiting mechanism also includes a rotating ring 18 rotatably connected to the outer periphery of the bottom end of the fixed platform 4, and four arc-shaped protrusions 19 arranged with equal arc on the outer periphery of the rotating ring 18. A driving block 20 is fixedly connected to the bottom end of the abutment strip 11 away from the fixed platform 4. The outer end face of the arc-shaped protrusion 19 is slidably engaged with the inner end face of the driving block 20. A rotating handle is fixedly connected to one side of the rotating ring 18, on the right side of the worktable 1 and near the top of the fixed platform 4. A cold heading mechanism is provided at the top. The cold heading mechanism includes a frame 21 fixedly connected to the upper right side of the workbench 1, and an annular cavity 22 opened below the fixed platform 4. A hydraulic rod 23 is fixedly connected to the middle of the top of the frame 21. The output shaft of the hydraulic rod 23 is fixedly connected to the cold heading head 24. A support sleeve 25 is movably sleeved inside the annular cavity 22. A circular boss 26 is fixedly connected to the outer periphery of the top of the support sleeve 25. A spring 27 is movably sleeved outside the support sleeve 25. The upper and lower ends of the spring 27 abut against the circular boss 26 and the inner bottom wall of the annular cavity 22, respectively. The diameter of the circular boss 26 is larger than that of the circular groove 13. The upper end face of the circular boss 26 is in contact with the inner top wall of the annular cavity 22.
[0025] In this embodiment, the synchronous opening and closing of the four sets of abutment bars 11 is achieved through the linkage of the rotating ring 18, the arc-shaped boss 19 and the drive block 20. The operator only needs to rotate the handle with one hand to complete the screw release process, which solves the problem of increased labor costs caused by the need for multiple people to operate the abutment in the prior art, and significantly improves the efficiency of single-person operation.
[0026] Working principle: The lower end of the nail-shaped metal part is placed against the inclined surface of the four abutment bars 11. When the nail-shaped metal part is pressed down, the abutment bars 11 move outward under the action of the inclined surface and compress the spring 17 until the nail body of the nail-shaped metal part is inserted into the support sleeve 25, and the nail head abuts against the upper end face of the circular boss 26 and is located inside and below the circular groove 13. At this time, the spring 17 pushes the abutment bars 11 back and abuts against the upper end face of the nail head to achieve axial positioning. Then, the hydraulic rod 23 drives the cold heading head 24 to descend and insert into the circular groove 13, pushing the nail-shaped metal part and the support sleeve 25 to move down synchronously and compress the spring 27 until the lower end face of the support sleeve 25 abuts against the support sleeve 25. The nail-shaped metal part, exposed on the support sleeve 25, is pressed into the forming groove 9 on the upper end face of the mold plate 3 to complete the cold heading. After forming, the hydraulic rod 23 lifts the cold heading head 24, and the spring 27 pushes the support sleeve 25 to rise and push out the formed screw. The operator rotates the handle counterclockwise to drive the rotating ring 18 to rotate. The arc-shaped boss 19 pushes the drive block 20 to make the four abutment bars 11 expand outward synchronously to release the screw. When it is necessary to switch the forming groove 9, the servo motor 8 drives the rotating shaft 5 to rotate through the preset program. The worm gear 7 drives the worm wheel 6 to make the mold plate 3 rotate precisely at a specified angle to ensure that the next forming groove 9 is automatically aligned with the circular groove 13.
[0027] It should be noted that the servo motor 8 is controlled by the PLC program to realize the automatic and precise rotation of the mold plate 3. The system presets the stop position corresponding to each forming groove 9. The servo motor 8 drives the worm gear 6 and worm 7 mechanism to make the mold plate 3 rotate accurately at a fixed angle each time.
[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
