Description

Technical Field

[0001] This utility model relates to the field of screw processing, and in particular to a thread rolling die for hexagonal screws. Background Technology

[0002] A thread rolling die for hexagonal screws is a tool used to process threads, commonly used in the manufacture of hexagonal screws, bolts, and other fasteners. It creates threads on the outer surface of the screw through a rolling process, allowing it to connect with a matching nut or other component.

[0003] Existing thread rolling plates, when rolling screws, use a moving thread rolling plate in conjunction with a fixed thread rolling plate to move the screw forward and roll the threads. However, during the movement of the screw, since there is no fixing device for the screw, the stability and accuracy of the thread rolling process cannot be ensured, which will cause the bolt to shift, resulting in uneven thread processing, affecting the shape and dimensional accuracy of the thread, and thus affecting the thread rolling effect. Utility Model Content

[0004] The main purpose of this utility model is to provide a thread rolling die for hexagonal screws, which can effectively solve the technical problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A thread rolling die for hexagonal screws includes a fixed thread rolling die, a movable thread rolling die on one side of the fixed thread rolling die, and a mounting plate on the top of the fixed thread rolling die. Two sets of movable slots are symmetrically distributed about the mounting plate on one side of the mounting plate. A clamping plate is movably disposed within each movable slot. A screw is rotatably connected to one side of each movable slot. One end of the screw passes through the mounting plate and is threadedly connected to one end of the clamping plate. A knob is fixedly connected to one end of the screw. A sliding component is provided on the fixed thread rolling die to facilitate the movement of the screw after it is fixed. A limit component is provided on the mounting plate to restrict the knob.

[0007] As a further embodiment of this utility model, the sliding assembly includes a sliding groove formed on the top of the fixed thread rolling plate, and a sliding column is slidably disposed in the sliding groove, with one end of the sliding column fixedly connected to the bottom of the mounting plate.

[0008] As a further embodiment of this utility model, a limiting rod is fixedly connected inside the sliding groove, and a circular through hole is provided on the sliding column, through which the limiting rod passes.

[0009] As a further embodiment of this utility model, the limiting component includes a mounting bracket disposed on one side of the mounting plate, a limiting groove is formed on one side of the knob, a limiting block is disposed in the limiting groove, and a movable rod is fixedly connected to one side of the limiting block.

[0010] As a further embodiment of this utility model, the limiting component also includes a spring disposed on one side of the mounting frame, one end of the movable rod passes through the mounting frame, a pull plate is disposed on one end of the movable rod, and one side of the pull plate is fixedly connected to one end of the spring.

[0011] As a further embodiment of this utility model, a connecting plate is provided on the top of the movable thread rolling plate, and a connecting groove is provided on one side of the connecting plate.

[0012] As a further embodiment of this utility model, a push plate is provided in the connecting groove, one side of the push plate is in contact with one side of the mounting plate, and a bolt is provided on the connecting plate, one end of the bolt being threadedly connected to the push plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] A screw is placed between two sets of clamping plates. Rotating the screw via a knob causes it to turn, and the screw, in conjunction with the thread, moves the clamping plates within a sliding groove, moving them to the screw surface and clamping it. A limiting component then secures the knob, preventing rotation and increasing the stability of the clamping plates. A moving thread rolling plate, working in conjunction with a sliding component, moves the screw, and the moving and fixed thread rolling plates perform thread rolling on the screw. This prevents bolt displacement, ensuring the stability and precision of the thread rolling process, resulting in uniform thread processing and preventing any impact on the thread shape and dimensional accuracy, thus improving the thread rolling effect.

[0015] The push plate is inserted into the connecting groove of the connecting plate, and the push plate is fixed on the connecting plate by using bolts and threaded connection. This connects the push plate with the movable thread rolling plate. When the movable thread rolling plate moves, the push plate drives the mounting plate to move with the movable thread rolling plate, which facilitates the thread rolling of the screw.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1-6 As shown, a thread rolling die for a hexagonal screw includes a fixed thread rolling die 1, a movable thread rolling die 2 on one side of the fixed thread rolling die 1, a mounting plate 5 on the top of the fixed thread rolling die 1, two sets of movable grooves 6 on one side of the mounting plate 5, the two sets of movable grooves 6 being symmetrically distributed about the mounting plate 5, a clamping plate 7 being movably disposed in the movable groove 6, a screw 8 being rotatably connected to one side of the movable groove 6, one end of the screw 8 passing through the mounting plate 5, the screw 8 being threadedly connected to one end of the clamping plate 7, and a knob 9 being fixedly connected to one end of the screw 8.

[0025] In this embodiment, a sliding component is provided on the fixed thread rolling plate 1, which facilitates the movement of the fixed screw; a limiting component is provided on the mounting plate 5, which is used to limit the knob 9.

[0026] First, place the screw to be thread-rolled between the two sets of clamping plates 7. Rotate the screw 8 by turning the knob 9. The screw 8, in conjunction with the thread, drives the clamping plates 7 to slide within the moving groove 6, moving the two sets of clamping plates 7 to the surface of the screw, clamping and restricting the screw. Then, fix the knob 9 by the limiting component to prevent the knob 9 from rotating, thereby increasing the stability of the clamping plates 7 in clamping the screw. Move the thread rolling plate 2, which, in conjunction with the sliding component, drives the screw to move. The moving thread rolling plate 2, in conjunction with the fixed thread rolling plate 1, performs thread rolling on the screw; preventing bolt displacement, thereby ensuring the stability and accuracy of the thread rolling process, making the thread processing uniform, and avoiding affecting the shape and dimensional accuracy of the thread, thus improving the thread rolling effect on the screw.

[0027] In this embodiment, the sliding component includes a sliding groove 3 opened on the top of the fixed thread rolling plate 1, a sliding column 4 is slidably arranged in the sliding groove 3, one end of the sliding column 4 is fixedly connected to the bottom of the mounting plate 5, a limit rod 16 is fixedly connected in the sliding groove 3, and a circular through hole is opened on the sliding column 4, through which the limit rod 16 passes.

[0028] The sliding column 4 slides on the fixed thread rolling plate 1 through the sliding groove 3. The sliding column 4 drives the mounting plate 5 to move, so that the screw can follow the moving thread rolling plate 2. At the same time, the limit rod 16 prevents the sliding column 4 from falling out of the sliding groove 3, ensuring the stability of the equipment during use.

[0029] In this embodiment, a connecting plate 17 is provided on the top of the movable thread rolling plate 2. A connecting groove 18 is provided on one side of the connecting plate 17. A push plate 19 is provided in the connecting groove 18. One side of the push plate 19 is attached to one side of the mounting plate 5. A bolt 20 is provided on the connecting plate 17. One end of the bolt 20 is threadedly connected to the push plate 19.

[0030] Insert the push plate 19 into the connecting groove 18 opened in the connecting plate 17, and use the bolt 20 to thread the push plate 19 to fix the push plate 19 on the connecting plate 17, thereby connecting the push plate 19 and the movable thread rolling plate 2 together. When the movable thread rolling plate 2 moves, the push plate 19 drives the mounting plate 5 to move with the movable thread rolling plate 2, which facilitates the thread rolling of the screw.

[0031] In this embodiment, the limiting component includes a mounting bracket 10 disposed on one side of the mounting plate 5, a limiting groove 12 formed on one side of the knob 9, a limiting block 13 disposed in the limiting groove 12, a movable rod 11 fixedly connected to one side of the limiting block 13, and a spring 14 disposed on one side of the mounting bracket 10. One end of the movable rod 11 passes through the mounting bracket 10, and a pull plate 15 is disposed at one end of the movable rod 11. One side of the pull plate 15 is fixedly connected to one end of the spring 14.

[0032] After clamping the screw, insert the limiting block 13 at one end of the movable rod 11 into the limiting groove 12 to fix the knob 9. At the same time, the pull plate 15, together with the spring 14 and the mounting bracket 10, applies pressure to the movable rod 11 to fix the limiting block 13 in the limiting groove 12, preventing the limiting block 13 from moving. Meanwhile, the pull plate 15 makes it easy to pull the limiting block 13 out of the limiting groove 12, making it easy to rotate the knob 9.

[0033] It should be noted that this utility model is a thread rolling plate for hexagonal screws. First, the screw to be rolled is placed between two sets of clamping plates 7. The screw rod 8 is rotated by turning the knob 9. The screw rod 8, in conjunction with the thread, drives the clamping plates 7 to slide in the moving groove 6, moving the two sets of clamping plates 7 to the surface of the screw, clamping and restricting the screw. The limiting block 13 at one end of the movable rod 11 is inserted into the limiting groove 12 to fix the knob 9. At the same time, the pull plate 15, in conjunction with the spring 14 and the mounting bracket 10, applies pressure to the movable rod 11, fixing the limiting block 13 in the limiting groove 12, preventing the knob 9 from rotating, thereby increasing the stability of the clamping plates 7 in clamping the screw. The moving thread rolling plate 2 moves, and the sliding column 4 slides on the fixed thread rolling plate 1 through the opened sliding groove 3. The sliding column 4 drives the mounting plate 5 to move, making it convenient for the screw to follow the moving thread rolling plate 2. The moving thread rolling plate 2, in conjunction with the fixed thread rolling plate 1, rolls the screw.
