Description

Technical Field

[0001] This utility model relates to the technical field of thread rolling equipment for steel wire, and in particular to a high-efficiency cold-rolled thread rolling die for steel wire. Background Technology

[0002] Cold-rolled threaded steel wire, with its high strength and stability, is widely used in construction, machinery manufacturing, and automotive parts industries. Thread rolling dies are the core equipment in the production process of cold-rolled threaded steel wire. Their main function is to roll the surface of the steel wire through a thread rolling mechanism, forming a threaded structure that meets specifications and subsequent assembly and usage requirements. Currently, thread rolling dies on the market typically include positioning components for fixing the steel wire and thread rolling components for rolling the threads, thus realizing the basic processing flow.

[0003] However, existing thread rolling dies have significant shortcomings in practical use: on the one hand, the positioning components mostly rely on manual adjustment of clamping force or use simple mechanical structures to fix the steel wire, making it difficult to accurately control clamping stability. During processing, problems such as steel wire deviation and shaking are prone to occur, leading to deviations in thread size accuracy and increasing the defect rate. On the other hand, the adjustment flexibility of the thread rolling components is poor. For steel wires of different diameters and specifications, it is often necessary to disassemble and replace the corresponding thread rolling components or adjust multiple complex structures, which is cumbersome and time-consuming. This not only reduces production efficiency but also increases the cost of adapting equipment to different products, making it difficult to meet diverse processing needs. Therefore, a high-efficiency cold-rolled thread steel wire rolling die is provided to solve the above problems. Utility Model Content

The die features stable positioning and clamping, ensuring processing accuracy, flexible adjustment of the rolling mechanism, and wide applicability, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency cold-rolled threaded steel wire rolling die, comprising: A wire positioning mechanism is used to position and clamp the wire to be rolled. The wire positioning mechanism includes a support platform. Two sets of first electric telescopic rods are fixedly connected to the lower part of the support platform. The movable ends of the two sets of first electric telescopic rods are fixedly connected to an I-shaped bracket. Each of the four extension ends of the I-shaped bracket is connected to two rotatable connecting transmission arms. Rotatable arc-shaped pressure arms are symmetrically installed on both sides of the support platform. Wire pressure rollers are rotatably connected to the upper two sides of the arc-shaped pressure arms. A wire rolling mechanism is provided above a support platform and is used to roll fixed steel wires.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0019] Reference Figures 1 to 6 In this embodiment of the utility model, a high-efficiency cold-rolled threaded steel wire rolling die includes: The wire positioning mechanism 1 is used to position and clamp the wire that needs to be rolled. The wire positioning mechanism 1 includes a support platform 11. Two sets of first electric telescopic rods 12 are fixedly connected to the lower part of the support platform 11. The movable ends of the two sets of first electric telescopic rods 12 are fixedly connected to an I-shaped bracket 13. The four extended ends of the I-shaped bracket 13 are each connected to two rotatable connecting transmission arms 14. Rotatable arc-shaped pressure arms 15 are symmetrically installed on both sides of the support platform 11. The lower ends of the four connecting transmission arms 14 and the four arc-shaped pressure arms 15 are rotatably connected one by one. Wire pressure rollers 16 are rotatably connected to the upper two sides of the arc-shaped pressure arms 15. The wire rolling mechanism 2 is set above the support platform 11 and is used to roll the fixed wire.

[0020] Using the above scheme: When it is necessary to position and clamp the steel wire, the two sets of first electric telescopic rods 12 below the support platform 11 are activated, and their movable ends drive the fixedly connected I-shaped brackets 13 to move in the vertical direction; when the I-shaped brackets 13 move, they will drive the four connecting transmission arms 14 to move synchronously. Since the extension ends of the connecting transmission arms 14 are respectively rotatably connected to the four arc-shaped pressure arms 15, and the arc-shaped pressure arms 15 are rotatably connected to the support platform 11, the connecting transmission arms 14 will drive the four sets of arc-shaped pressure arms 15 to rotate around the rotation point on the support platform 11, thereby causing the steel wire pressure rollers 16 rotatably connected on both sides above the arc-shaped pressure arms 15 to move closer to the steel wire and clamp it, thus completing the steel wire positioning; after the steel wire is positioned, the steel wire rolling mechanism 2 located above the support platform 11 is activated to perform the rolling operation on the fixed steel wire.

[0021] Four second electric telescopic rods 17 are also fixedly connected to the support platform 11. Two second electric telescopic rods 17 located at the same end of the support platform 11 form a group. The movable end of each group of second electric telescopic rods 17 is fixedly connected to a group of side brackets 18. Two groups of bottom support rollers 19 are rotatably connected between the two groups of side brackets 18. The two groups of bottom support rollers 19 and the four groups of steel wire pressure rollers 16 work together to clamp the steel wire.

[0022] The above scheme is adopted: During the steel wire positioning process, the four second electric telescopic rods 17 (two in a group) fixedly connected above the support platform 11 are started synchronously. The movable end of each group of second electric telescopic rods 17 drives the corresponding fixedly connected side brackets 18 to move in the vertical direction. Since two sets of bottom support rollers 19 are rotatably connected between the two sets of side brackets 18, when the side brackets 18 move, they will drive the bottom support rollers 19 to adjust their vertical position, so that the top of the bottom support rollers 19 is in contact with the bottom of the steel wire. At the same time, in conjunction with the steel wire pressure rollers 16 above the arc-shaped pressure arm 15, the steel wire that needs to be rolled is stably clamped between the bottom of the two sets of steel wire pressure rollers 16 and the top of the two sets of bottom support rollers 19, so as to avoid the steel wire from shifting during positioning or subsequent rolling, and improve the positioning stability.

[0023] The wire rolling mechanism 2 also includes a third electric telescopic rod 21, of which four sets are provided. The third electric telescopic rods 21 are fixedly connected to the upper surface of the support platform 11. The movable ends of the multiple third electric telescopic rods 21 are jointly fixedly connected to an upper support plate 22. An upper fixed plate 23 is fixedly connected to the upper support plate 22. A fourth electric telescopic rod 24 is fixedly connected to the inner side of the upper fixed plate 23. The movable end of the fourth electric telescopic rod 24 is fixedly connected to a rotating seat 25. The two ends of the rotating seat 25 are rotatably connected to upper rotating push plates 26. Two sets of lower mounting housings are also provided below the upper support plate 22. 27. A thread rolling disc 28 is rotatably connected to the inner side of the lower mounting housing 27. A drive motor 29 is fixedly connected to the side of the lower mounting housing 27. The rotation shaft of the drive motor 29 passes through the lower mounting housing 27 and is fixedly connected to the thread rolling disc 28. Two sets of symmetrical sliding grooves are opened on the lower surface of the upper support plate 22. A slider that matches the sliding groove is fixedly connected to the upper part of the lower mounting housing 27. A connecting post 210 is fixedly connected to the upper part of the lower mounting housing 27. A guide groove that extends in the same direction as the sliding groove is opened on the upper support plate 22. The upper part of the connecting post 210 passes through the guide groove and is rotatably connected to the upper rotating push plate 26 at the corresponding position.

[0024] Using the above scheme: When it is necessary to perform thread rolling on the fixed steel wire, the four sets of third electric telescopic rods 21 above the support platform 11 are activated. The movable end of the third electric telescopic rod 21 drives the fixedly connected upper support plate 22 to move vertically, so as to adjust the vertical distance between the component below the upper support plate 22 and the steel wire, ensuring that the thread rolling disc 28 can be accurately aligned with the steel wire processing position; then the fourth electric telescopic rod 24 fixedly connected to the side of the upper fixed plate 23 is activated. The movable end of the fourth electric telescopic rod 24 drives the fixedly connected rotating seat 25 to move horizontally. When the rotating seat 25 moves, it will drive the two sets of upper rotating push plates 26 connected to the upper rotating part to rotate around the rotation point; due to the upper rotating push... The plate 26 is rotatably connected to the connecting column 210 fixedly connected to the upper part of the lower mounting housing 27, and the slider above the lower mounting housing 27 is adapted to the slide groove below the upper support plate 22. When the upper rotating push plate 26 rotates, it will drive the lower mounting housing 27 to slide along the slide groove, thereby adjusting the horizontal distance between the two sets of lower mounting housings 27, so that the thread rolling disc 28 rotatably connected inside the lower mounting housing fits against both sides of the steel wire. Finally, the drive motor 29 fixedly connected to the side of the lower mounting housing 27 starts, and its rotating shaft passes through the lower mounting housing 27 and drives the fixedly connected thread rolling disc 28 to rotate at high speed. The rotating thread rolling disc 28 performs cold rolling thread rolling on the clamped and stable steel wire, completing the steel wire rolling operation.

[0025] The working principle of this utility model is as follows: First, the steel wire is initially placed and supported and adjusted. The operator places the steel wire to be processed on the support platform 11. The four second electric telescopic rods 17 on the support platform 11 are activated. The movable ends of the four second electric telescopic rods 17 drive the side brackets 18 to move vertically, thereby adjusting the position of the bottom support rollers 19 rotatably connected between the two sets of side brackets 18, so that the upper surface of the bottom support rollers 19 is in contact with the bottom of the steel wire, providing stable bottom support for the steel wire and ensuring that the steel wire is initially in the vertical position to be processed. Next, the steel wire is clamped and positioned. The two sets of first electric telescopic rods 12 below the support platform 11 are activated, and the movable end drives the I-shaped bracket 13 to move vertically. The four connecting transmission arms 14 rotatably connected to the I-shaped bracket 13 move accordingly. Since the connecting transmission arms 14 are rotatably connected to the four arc-shaped pressure arms 15 respectively, and the arc-shaped pressure arms 15 are rotatably connected to the support platform 11, the connecting transmission arms 14 will push the four sets of arc-shaped pressure arms 15 to rotate around the support platform 11, so that the steel wire pressure roller 16 above the arc-shaped pressure arms 15 moves closer to the steel wire, and finally cooperates with the bottom support roller 19 to stably clamp the steel wire between the two, preventing displacement during processing. Finally, the thread rolling operation is performed. The drive motor 29 on the side of the lower mounting housing 27 is started, and its rotating shaft passes through the lower mounting housing 27 and drives the thread rolling discs 28 to rotate at high speed. The two sets of rotating thread rolling discs 28 perform cold rolling on the steel wire that is stably clamped, rolling threads on the surface of the steel wire, thus completing the efficient cold-rolled threaded steel wire processing process.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
