Abstract
Description
Technical Field
[0001] This utility model relates to the field of thread rolling head technology, and in particular to a thread rolling head. Background Technology
[0002] A thread rolling head is a tool used to process threads on metal materials. It is usually used in cold rolling processes. Unlike traditional thread cutting, thread rolling is a non-cutting processing method. Through the rotation and axial feed of the rolling head, the metal material is plastically deformed, thereby forming threads.
[0003] When threading is required, the workpiece is moved between multiple forming rollers on the rolling head, and the threads on the workpiece are processed by the forming rollers. When installing the forming rollers, the forming rollers are first fitted onto the column on one side of the rolling head, and then the forming rollers are pressed by a pressure plate. The pressure plate is then fixed to the rolling head with bolts. During workpiece processing, cooling water is sprayed to cool the rolling head. However, the bolts are corroded by the cooling water over a long period of time, and the bolt heads may rust, resulting in the bolts being unable to be turned. Therefore, this solution proposes a thread rolling head to solve the above problems. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] This utility model provides, for example Figure 1-4 The thread rolling head shown includes:
[0035] Roller head body 1;
[0036] Pressure plate 2 is disposed on one side of the roller head body 1;
[0037] Bolt 3, a mounting hole 201 is provided on one side of the pressure plate 2, and bolt 3 is inserted and connected to the inner wall of the mounting hole 201.
[0038] Sealing gasket 4 is inserted into the interior of mounting hole 201;
[0039] A rotating plate 5 is fixedly connected to one side of the sealing gasket 4. A rotating assembly 6 for moving and rotating the rotating plate 5 is provided on one side of the rotating plate 5. A positioning assembly 7 for limiting the rotation of the rotating plate 5 is provided on one side of the rotating plate 5.
[0040] It should be noted that the roller head body 1, pressure plate 2 and bolt 3 are MS-001 thread roller heads; the sealing gasket 4 is made of rubber, which is squeezed against the bolt head during use, and the sealing gasket 4 protects the hole on the bolt head to prevent rusting caused by prolonged contact with cooling water; the rotating plate 5 is used to squeeze the sealing gasket 4 towards one side of the bolt 3.
[0041] Specifically, the rotating component 6 includes:
[0042] A connecting rod 603 is fixedly connected to one side of the rotating plate 5. A through hole 601 is provided on one side of the pressure plate 2, and the connecting rod 603 is inserted into the through hole 601.
[0043] Rotating block 605 is fixedly connected to one end of connecting rod 603. A cavity 606 is opened on the inner wall of the through hole 601, and rotating block 605 is inserted into the cavity 606.
[0044] A pusher is provided on one side of the rotating block 605 and is used to push the rotating block 605.
[0045] It should be noted that the through hole 601 is adapted to the connecting rod 603, allowing the connecting rod 603 to be inserted into the through hole 601, and the through hole 601 restricts the movement direction of the connecting rod 603. When it is necessary to protect the bolt head of the bolt 3, first insert the sealing gasket 4 on the rotating plate 5 into the mounting hole 201 to seal the bolt head of the bolt 3. Then, the pushing component drives the rotating block 605 to press away from the rotating plate 5, so that the sealing gasket 4 on one side of the rotating plate 5 is always pressed towards the bolt 3, thereby preventing the sealing gasket 4 from moving away from the bolt 3. When it is necessary to tighten the bolt 3, first move the rotating plate 5 away from the bolt 3 and remove the sealing gasket 4 from the mounting hole 201. Then, rotate the rotating plate 5 around the connecting rod 603 in a circle until the rotating plate 5 is separated from the mounting hole 201. Then, tighten the bolt 3 with a wrench.
[0046] Specifically, the driving components include:
[0047] A connecting block 604 is provided on one side of the rotating block 605, and a limiting member 9 is provided on one side of the connecting block 604;
[0048] Elastic block 602 is fixedly connected to one side of connecting block 604 and to the inner wall of one side of cavity 606.
[0049] It should be noted that the elastic block 602 is made of rubber, which has the property of being deformable. During use, it is used to push the connecting block 604 away from the elastic block 602. The connecting block 604 is attached to the rotating block 605 but not fixed.
[0050] Specifically, the connecting block 604 has a first through hole in the middle, and the connecting rod 603 is inserted into the inside of the first through hole. The elastic block 602 has a second through hole in the middle, and the connecting rod 603 is inserted into the inside of the second through hole.
[0051] It should be noted that the first and second through holes are used for the connecting rod 603 to pass through the connecting block 604 and the elastic block 602, and to connect with the rotating block 605 on one side of the connecting block 604.
[0052] Specifically, limiting component 9 includes:
[0053] Slider 902 is fixedly connected to the bottom of connecting block 604;
[0054] The slide groove 901 is formed on the inner wall at the bottom of the cavity 606, and the slider 902 is inserted and connected inside the slide groove 901.
[0055] It should be noted that the movement direction of the slider 902 is determined by the restriction of the slide groove 901. The slider 902 is fixed to the bottom of the connecting block 604. When the connecting block 604 moves, it drives the slider 902 to slide inside the slide groove 901. When the connecting block 604 needs to rotate, the slider 902 on one side is restricted by the slide groove 901, thereby restricting the rotation of the connecting block 604 by restricting the movement direction of the slider 902.
[0056] Specifically, positioning component 7 includes:
[0057] Positioning block 701 is fixedly connected to one side of rotating plate 5;
[0058] The positioning groove 702 is opened on one side of the pressure plate 2, and the positioning block 701 is inserted and connected inside the positioning groove 702.
[0059] It should be noted that the positioning groove 702 is adapted to the positioning block 701, allowing the positioning block 701 to pass into the interior of the positioning groove 702. When it is necessary to restrict the rotation of the rotating plate 5, the rotating plate 5 is first rotated to align the positioning block 701 with the positioning groove 702. Then, the rotating plate 5 is moved to one side of the pressure plate 2 by the pushing member, so that the positioning block 701 is inserted into the interior of the positioning groove 702. The positioning groove 702 restricts the movement of the positioning block 701, and the rotation of the rotating plate 5 is restricted by the positioning block 701 that restricts the movement and the connecting rod 603 that restricts the movement.
[0060] Specifically, a lifting block 8 is fixedly connected to one side of the rotating plate 5, and the lifting block 8 is used to move the position of the rotating plate 5.
[0061] It should be noted that the lifting block 8 is fixedly connected to the rotating plate 5 and protrudes from the pressure plate 2. Thus, when it is necessary to move the rotating plate 5 away from the pressure plate 2, the lifting block 8 can be moved by the finger, and the rotating plate 5 can be moved by the lifting block 8.
[0062] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
