Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stud processing, in particular to a stud thread rolling tooling capable of preventing gasket shedding. Background Art
[0002] A stud is a cylindrical fastener with threads at both ends. Studs are generally used to connect large parts, with one end screwed into the main body and the other end installed in an accessory that needs to be frequently disassembled. The processing and manufacturing process of studs generally can be divided into steps such as bar drawing, cutting, heating, forging and forming, turning, and thread rolling.
[0003] During the process of rolling the double - head thread, currently, a thread rolling machine is commonly used for the surface thread forming processing of double - head studs. The processing principle of the thread rolling machine is that the cleaned stud blank is placed into the processing area of the thread rolling machine through a feeding device, and then a push plate is used to push the stud between two thread rolling plates. At this time, the gasket on the double - head stud will enter the rolling grooves between the two thread rolling plates. Then, the thread rolling plates are started. With the relative movement of the thread rolling plates, the blank is extruded and gradually forms threads. At the same time, the gasket is restricted on the stud. During the processing, it is necessary to pay attention to observing the forming situation of the threads and timely adjust the parameters to ensure the quality and accuracy of the threads. Finally, the processed studs are sent out through a discharging device for inspection.
[0004] When rolling the double - head studs currently, most of them will place the double - head studs at a specified position and then start the push plate to send the double - head studs between the two thread rolling plates. However, when the existing tooling places the double - head studs, the gasket is likely to hit the thread rolling plate during the process of the push plate pushing the double - head stud, resulting in an incorrect position of the double - head stud when it enters between the two thread rolling plates. There may be a problem of gasket shedding. At the same time, inaccurate position may also pose a risk of uneven thread spacing and inconsistent thread depth. Summary of the Invention
[0005] The purpose of the utility model is to provide a stud thread rolling tooling capable of preventing gasket shedding to solve the problem that the position of the double - head stud when it enters between the two thread rolling plates is incorrect and there may be a problem of gasket shedding.
[0006] The utility model specifically adopts the following technical solutions to achieve the above - mentioned purpose:
[0007] A stud thread rolling tooling capable of preventing gasket shedding, including a base. A first fixed seat is fixedly connected to the top of the base.

[0008] By adopting the above technical solution, the stud is placed between the first fixing seat and the second fixing seat, and then the push plate is started to move between the first fixing seat and the second fixing seat. When the push plate moves, it will push the stud, so that the stud is pushed between the two thread rolling plates. Then, the two thread rolling plates are started to move, so as to carry out the thread rolling process of the stud. The gasket on the stud can be fixed by the fixing mechanism, so as to ensure the smooth progress of the thread rolling work.
[0009] Further, the fixing mechanism includes a plurality of springs fixedly connected to the outside of the second fixing seat at equal intervals.

[0011] Further, protective pads are fixedly connected to the inner sides of the two placing grooves, and the shape of the protective pads is adapted to that of the placing grooves.
[0012] By adopting the above technical solution, the protective pads can reduce the direct hard contact between the rotating plate and the stud and the gasket.
[0013] Further, a threaded rod is threadedly connected to the outside of the second fixing seat. One end of the threaded rod away from the second fixing seat is fixedly connected with a handle. A limiting groove is formed in the inner side of the second fixing seat. A limiting block is slidably arranged in the limiting groove. One end of the threaded rod close to the second fixing seat penetrates through the second fixing seat and is rotatably connected with the limiting block.
[0014] By adopting the above technical solution, flexible adjustment can be carried out according to studs of different sizes.
[0015] Further, a plurality of protrusions are fixedly connected to the side of the limiting block away from the second fixing seat at equal intervals, and one end of the protrusion away from the limiting block is conical.
[0016] By adopting the above technical solution, multi-point contact can disperse the pressure and make the contact more uniform and stable.
[0017] Further, an auxiliary rod is fixedly connected to the side of the limiting block away from the protrusion. One end of the auxiliary rod close to the second fixing seat penetrates through the second fixing seat, and the auxiliary rod is slidably connected with the second fixing seat.
[0018] By adopting the above technical solution, the auxiliary rod provides an additional supporting point for the limiting block.
[0019] Furthermore, a first resistance block is fixedly connected to the outer side of the push plate, a second resistance block is fixedly connected to the outer side of the rotating plate, the first resistance block is in contact with the second resistance block, and the contact surface between the first resistance block and the resistance block is set as an inclined surface.
[0020] By adopting the above technical solution, the stud can be pushed out smoothly.
[0021] Furthermore, a slide groove is provided on the top of the second fixing seat, a sliding block is fixedly connected to the push plate, and the sliding block is slidably connected to the slide groove.
[0022] By adopting the above technical solution, the push plate can remain stable when moving.

[0034] The following will further elaborate on the present utility model in conjunction with the attached Figures 1-6 drawings.
[0035] An embodiment of the present utility model discloses a stud rolling tooling that can prevent the gasket from falling off.
[0036] Referring to Figure 1 and Figure 2 , a stud rolling tooling that can prevent the gasket from falling off includes a base 1. A first fixing seat 2 is fixedly connected to the top of the base 1. A second fixing seat 3 is fixedly connected to the top of the base 1 on one side of the first fixing seat 2. A double-headed stud 4 with a gasket is placed between the first fixing seat 2 and the second fixing seat 3. The gasket is sleeved on one end of the double-headed stud 4. As Figure 6 shown, a push plate 5 is slidably connected between the first fixing seat 2 and the second fixing seat 3. A fixing mechanism is provided on one side of the second fixing seat 3 close to the second fixing seat 3.
[0037] When threading the double-headed stud 4, first place the double-headed stud 4 between the first fixing seat 2 and the second fixing seat 3, and then start the push plate 5 to move between the first fixing seat 2 and the second fixing seat 3. The movement of the push plate 5 will push the double-headed stud 4, so that the double-headed stud 4 is pushed between the two threading plates. Then start the two threading plates to move, so as to thread the double-headed stud 4. The gasket on the double-headed stud 4 can be fixed through the fixing mechanism, reducing the risk of the gasket falling off, thereby ensuring the smooth progress of the threading work.
[0038] Referring to Figures 1 to 3 , the fixing mechanism includes a plurality of springs 6 fixedly connected to the outside of the second fixing seat 3 at equal intervals. A rotating shaft 7 is fixedly connected to the top of the second fixing seat 3. A rotating plate 8 is rotatably connected to the outside of the rotating shaft 7. One end of the spring 6 away from the first fixing seat 2 is fixedly connected to the rotating plate 8. Placing grooves 9 are formed on the top of both the rotating plate 8 and the first fixing seat 2. The two placing grooves 9 are semicircular.
[0039] Among them, protective pads 10 are fixedly connected to the inner sides of the two placing grooves 9. The shape of the protective pads 10 is adapted to the placing grooves 9.
[0040] When fixing the stud 4, the stud 4 is placed in the placement groove 9. At this time, the elastic potential energy of the spring 6 acts on the rotating plate 8, so that the rotating plate 8 rotates outside the rotating shaft 7. The rotating plate 8 rotates and drives the stud 4 to be fixed in the placement groove 9, reducing the gasket from hitting the thread rolling plate when pushing it into the thread rolling plate. In combination with the push plate, the stud 4 can smoothly enter the thread rolling plate, reducing accidents caused by gasket collision.
[0041] When the rotating plate 8 clamps the stud 4, the protective pad 10 is made of rubber, which has a certain degree of softness. When the rotating plate 8 clamps the stud 4 and the gasket, the rubber protective pad 10 can reduce the direct hard contact between the rotating plate 8 and the stud 4 and the gasket, thereby effectively reducing scratches or wear on the surfaces of the stud 4 and the gasket.
[0042] Reference Figure 2 and Figure 4 The outer side of the fixed seat 23 is threadedly connected with a threaded rod 11, and the end of the threaded rod 11 away from the fixed seat 23 is fixedly connected with a handle 12. A limiting groove 13 is provided on the inner side of the fixed seat 23, and a limiting block 14 is slidably arranged inside the limiting groove 13. The end of the threaded rod 11 close to the fixed seat 23 passes through the fixed seat 23 and is rotatably connected to the limiting block 14.
[0043] In addition, a surface of the limiting block 14 away from the fixing seat 2 3 is fixedly connected with a plurality of protrusions 15 at equal intervals, and an end of the protrusion 15 away from the limiting block 14 is configured to be conical.
[0044] In addition, an auxiliary rod 16 is fixedly connected to a surface of the limiting block 14 away from the protrusion 15 , and an end of the auxiliary rod 16 close to the fixing seat 2 3 penetrates the fixing seat 2 3 , and the auxiliary rod 16 is slidably connected to the fixing seat 2 3 .
[0045] When the studs 4 of different sizes are used, the threaded rod 11 is driven to rotate by rotating the handle 12, and the fixing seat 2 is threadedly connected with the threaded rod 11, so that the threaded rod 11 moves inside the fixing seat, and the movement of the threaded rod 11 drives the limit block 14 to resist the rotating plate 8. The rotating plate 8 starts to rotate after being subjected to force, thereby increasing the area inside the placement groove 9, so that it can be flexibly adjusted according to the studs 4 of different sizes;
[0046] When the stop block 14 contacts the rotating plate 8, the stop block 14 drives the protrusion 15 to squeeze the rotating plate 8. The protrusion 15 makes the contact between the stop block 14 and the rotating plate 8 no longer a plane contact, but a multi-point contact. The multi-point contact can disperse the pressure and make the contact more uniform and stable.
[0047] When the limit block 14 moves, the auxiliary rod 16 provides an additional support point for the limit block 14 , so that the limit block 14 remains stable when moving.
[0048] Referring to Figure 1 and Figure 3 On the outer side of the push plate 5, a first abutting block 17 is fixedly connected. On the outer side of the rotating plate 8, a second abutting block 18 is fixedly connected. The first abutting block 17 abuts against the second abutting block 18, and the contact surface between the first abutting block 17 and the abutting block is set as an inclined surface.
[0049] Among them, a sliding groove 19 is opened at the top of the second fixed seat 3. A sliding block is fixedly connected to the push plate 5, and the sliding block is slidably connected to the sliding groove 19.
[0050] When the push plate 5 moves, the push plate 5 will drive the second abutting block 18 to abut against the first abutting block 17. Since the contact surface between the second abutting block 18 and the abutting block is set as an inclined surface, the second abutting block 18 will rotate after being stressed, so that the rotating plate 8 moves away from the first fixed seat 2, making the internal space of the placement groove 9 slightly larger, thus facilitating the push plate 5 to push the stud 4 between the two thread rolling dies. Then, through the elastic potential energy of the spring 6 and the limit of the protrusion 15, the rotating plate 8 is reset;
[0051] When the push plate 5 moves, the sliding block and the sliding groove 19 provide a guiding function for the push plate 5, so that the push plate 5 can move smoothly.
[0052] Working principle: Place the stud 4 between the first fixed seat 2 and the second fixed seat 3, and then start the push plate 5 to move between the first fixed seat 2 and the second fixed seat 3. The movement of the push plate 5 will push the stud 4, so that the stud 4 is pushed between the two thread rolling dies. Then start the two thread rolling dies to move, so as to carry out the thread rolling process of the stud 4. Place the stud 4 into the placement groove 9. At this time, the elastic potential energy of the spring 6 acts on the rotating plate 8, so that the rotating plate 8 rotates on the outer side of the rotating shaft 7. The rotation of the rotating plate 8 will fix the gasket of the stud 4 in the placement groove 9, which can ensure that the gasket will not hit the thread rolling die when being pushed into the thread rolling die, and cooperate with the pushing plate to make the stud 4 smoothly enter the thread rolling die.
[0053] By rotating the handle 12 to drive the threaded rod 11 to rotate, since the first fixed seat 2 is threadedly connected to the threaded rod 11, the threaded rod 11 moves inside the fixed seat, and the movement of the threaded rod 11 will drive the limiting block 14 to abut against the rotating plate 8. The rotating plate 8 will start to rotate after being stressed, so that the area inside the placement groove 9 becomes larger, so that it can be flexibly adjusted according to the studs 4 of different sizes. The auxiliary rod 16 provides an additional support point for the limiting block 14, so that the limiting block 14 moves smoothly.
