Description

Technical Field

[0001] This utility model relates to the field of high-performance rebar rolling, and in particular to a steel roll adjustment structure. Background Technology

[0002] Rebar, commonly known as hot-rolled ribbed steel bar, is a type of small-section steel. Its grade is determined by HRB (High Strength Ratio) and yield strength characteristic value. It features high strength, good plasticity, and excellent weldability, and is widely used in civil engineering projects such as housing, bridges, and roads. Steel rolls are key components in rebar processing. During rolling, they apply pressure to the steel through rotation, causing plastic deformation and forming the desired cross-sectional shape and dimensions.

[0003] In the prior art, some steel roll adjustment structures require the use of a cylinder to move two rolls toward or away from each other to adjust the distance between the two rolls. Then, starting the cylinder will drive the rolls to rotate and process the threaded rod. However, because the tooth shape on the roll surface is fixed, it is difficult to adapt to different specifications of threaded steel (such as diameter and rib shape), thus narrowing the applicable range of the roll. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a steel roll adjustment structure to solve the problem that some steel roll adjustment structures mentioned in the background technology are difficult to adapt to different specifications of threaded steel (such as diameter and rib shape) due to the fixed tooth shape on the roll surface, thus narrowing the applicable range of the roll.

[0043] 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.

[0044] Please see Figures 1 to 6This utility model provides a technical solution: a steel roll adjustment structure, comprising: a support frame 1, a connecting seat 2 disposed within the support frame 1, a rotary motor 3 fixedly mounted on one side of the connecting seat 2, a roller shaft 4 rotatably connected within the connecting seat 2, the roller shaft 4 being fixedly connected to the output end of the rotary motor 3, the roller shaft 4 being cylindrical, with columnar flanges formed at both ends for mounting connecting plates 402 and transmission plates 404, clearance grooves 401 provided on both sides of the roller shaft 4, and connecting plates 4 fixedly connected to the surface of the roller shaft 4. 02. A threaded rod 403 is internally threaded to the connecting plate 402. One end of the threaded rod 403 is rotatably connected to a transmission plate 404. The transmission plate 404 and the roller shaft 4 are slidably connected. A transmission rod 405 is rotatably connected to one side of the transmission plate 404. A fixing block 406 is rotatably connected to the other end of the transmission rod 405. The first roller sleeve 5 and the second roller sleeve 6 are mated and fitted on the surface of the roller shaft 4. A first fixing groove 501 is opened on the inner side of the first roller sleeve 5, and a second fixing groove 601 is opened on the inner side of the second roller sleeve 6.

[0045] The rotary motor 3, installed on one side of the connecting seat 2, drives the first roller sleeve 5 and the second roller sleeve 6 to rotate via the roller shaft 4, thus processing the threaded steel. Rotating the threaded rod 403 causes it to move within the connecting plate 402 fixed to the surface of the roller shaft 4. Due to the restriction at both ends of the roller shaft 4, the transmission plate 404 will move along the axial direction of the roller shaft 4, thereby causing several transmission rods 405 connected to one side of the transmission plate 404 to swing. This, in turn, causes the fixing block 406 connected to the other end of the transmission rod 405 to move within the relief groove 401 until the fixing block 406 completely disengages from the first fixing groove 501 inside the first roller sleeve 5 and the second fixing groove 601 inside the second roller sleeve 6. The first roller sleeve 5 and the second roller sleeve 6 can then be removed from the surface of the roller shaft 4. This allows for the replacement of the first roller sleeve 5 and the second roller sleeve 6 with different tooth profiles according to the specifications of the threaded steel (such as diameter and rib shape), enhancing the applicability of the steel roll.

[0046] Furthermore, a sliding groove 407 is provided on the inner side of the clearance groove 401, and a slider 408 is fixedly connected to one side of the fixing block 406. The slider 408 and the sliding groove 407 are slidably connected.

[0047] As the fixed block 406 moves along the relief groove 401, the sliders 408 fixedly connected to both sides of the fixed block 406 will slide along the slide groove 407, thereby limiting the movement trajectory of the fixed block 406 and preventing it from leaving the relief groove 401.

[0048] Furthermore, a handle 103 is fixedly connected to the outside of the support frame 1, and a soft pad (not shown in the figure) is fitted on the outside of the handle 103. Several lifting slots 104 are provided on the inside of the handle 103, and the lifting slots 104 are square.

[0049] The handle 103 facilitates the handling of the entire steel roll structure, and the lifting groove 104 located inside the handle 103 facilitates the lifting of the structure.

[0050] Please see Figure 1 The present invention provides a technical solution: the support frame 1 has guide grooves 101 on both sides, the guide grooves 101 and the connecting seat 2 are slidably connected, and the support frame 1 has a cylinder 102 fixedly installed on the outside of the support frame 1, the cylinder 102 and the connecting seat 2 are fixedly connected.

[0051] The starting cylinder 102 will drive the connecting seat 2 connected to its output end to slide along the guide groove 101 opened on both sides of the support frame 1, thereby adjusting the distance between the two rollers 4, so that the structure can be adapted to different processing requirements and further improve the applicability of the structure.

[0052] Please see Figures 4 to 6 The present invention provides a technical solution: a positioning block 502 is fixedly connected to one side of the first roller sleeve 5, and a sealing ring 503 is sleeved on the surface of the positioning block 502; a positioning groove 602 is opened on one side of the second roller sleeve 6, and the size of the positioning groove 602 is the same as the size of the sealing ring 503.

[0053] When the first roller sleeve 5 is docked with the second roller sleeve 6, the positioning block 502 fixed on one side of the first roller sleeve 5 will be inserted into the positioning groove 602 opened on one side of the second roller sleeve 6, thereby preventing the first roller sleeve 5 from being misaligned after docking with the second roller sleeve 6. The sealing ring 503 sleeved on the surface of the positioning block 502 can improve the sealing performance of the first roller sleeve 5 and the second roller sleeve 6 during use.

[0054] Preferably, the dimensions of the first fixing groove 501 are the same as those of the second fixing groove 601, the inner walls of the first fixing groove 501 and the second fixing groove 601 are inclined, and the fixing block 406 is trapezoidal.

[0055] Since the inner walls of the first fixing groove 501 and the second fixing groove 601 are both inclined and the fixing block 406 is trapezoidal, the fixing block 406 can apply a thrust to the first roller sleeve 5 and the second roller sleeve 6 after being inserted into the first fixing groove 501 and the second fixing groove 601, so as to bring the two closer together, thereby further improving the sealing between the first roller sleeve 5 and the second roller sleeve 6.

[0056] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
