Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically a steel strand cutting device. Background Technology

[0002] In many engineering applications, steel strands need to be cut to specific lengths according to specific design requirements and construction conditions. For example, in prestressed concrete structures, the lengths of prestressing tendons in different parts may be different. Cutting steel strands can accurately obtain the required length of prestressing tendons, so that they can better adapt to the shape and stress requirements of the structure, and ensure the accuracy and effectiveness of prestressing application. Currently, integrated steel strand cutting machines are used to cut steel strands.

[0003] After the section of the steel strand to be cut is placed inside the cutting machine, both ends of the section are suspended in the air. When the tension of the external support equipment on the steel strand weakens, the suspended section of the steel strand will sag under its own weight, causing the section to be cut to be out of tension. As a result, multiple cuts are required when cutting the steel strand with a cutter, making it impossible to cut the steel strand effectively in one go, resulting in poor cutting efficiency. To address the shortcomings of existing technology, we propose a steel strand cutting device to solve the above problems. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] This application provides a steel strand cutting device that solves the problem that when the tension of the external support equipment on the steel strand weakens, the suspended part of the steel strand will sag under its own weight, causing the part of the steel strand to be cut to be not taut. This results in the need for repeated cutting when the steel strand is cut with a cutter. The device clamps and supports both ends of the part of the steel strand to be cut, ensuring that the part of the steel strand to be cut is taut.

[0025] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0026] This utility model discloses a steel strand cutting device.

[0027] According to the appendix Figure 1-5As shown, the machine includes a cutting machine body 1, a hydraulic cylinder 2 installed on the inner wall of the cutting machine body 1, a cutter 3 installed on one side of the hydraulic cylinder 2, and a control handle 4 rotatably installed on the top of the cutting machine body 1 to control the movement of the cutter 3. The cutting machine body 1, hydraulic cylinder 2, cutter 3, and control handle 4 constitute an integrated steel strand cutting machine, model QY-48. When in use, as shown in the attached diagram... Figure 1 As shown, one end of the steel strand is passed through the interior of the cutting machine body 1 so that the part to be cut corresponds to the position of the cutter 3. Then, by sequentially lifting and pressing the control handle 4, the hydraulic cylinder 2 is activated, and the cutter 3, driven by the hydraulic cylinder 2, sequentially cuts the steel strand.

[0028] See attached document Figure 1-4 The main body 1 of the cutting machine is equipped with support mechanisms 5 on both sides. When cutting the steel strand, the support mechanisms 5 can clamp and support both ends of the part of the steel strand to be cut, so that the part of the steel strand to be cut is in a supported state, so that the cutter 3 can cut the steel strand in one go, avoiding the need for repeated cutting operations. The support mechanism 5 includes a support box 51. Two sets of support boxes 51 are fixedly installed on both sides of the main body 1 of the cutting machine, and a first support column 52 and a second support column 53 are slidably installed inside the two sets of support boxes 51, as shown in the attached figure. Figure 5 As shown, the outer walls of the first pillar 52 and the second pillar 53 are provided with limiting grooves 57 for limiting the connection between the first pillar 52 and the second pillar 53 and the support box 51. Multiple sets of support blocks 54 are fixedly installed on the top surface of the first pillar 52 and the second pillar 53, and the outer wall of one end of the steel strand is clamped and supported by two adjacent sets of support blocks 54.

[0029] See attached document Figure 3-4 The electric telescopic rod 55 and the linkage assembly 56 are both located inside the support box 51. One end of the electric telescopic rod 55 is fixedly connected to the inner wall of the support box 51. The linkage assembly 56 includes a first toothed plate 561, a second toothed plate 562, and a gear 563 in a meshing state. One end of the first toothed plate 561 is fixedly connected to one side of the first support column 52, one end of the second toothed plate 562 is fixedly connected to one side of the second support column 53, one end of the electric telescopic rod 55 is connected to one side of the second support column 53, and the gear 563 is rotatably located inside the support box 51. Figure 4As shown, gear 563 is located between the first toothed plate 561 and the second toothed plate 562. The combination of electric telescopic rod 55 and linkage component 56 synchronously controls the two adjacent sets of support blocks 54. Before cutting the steel strand, the electric telescopic rod 55 is first activated, so that the electric telescopic rod 55 controls the second column 53 and the support block 54 set on the top surface of the second column 53 to move towards the steel strand. During this process, the second toothed plate 562 moves synchronously with the second column 53, so that the second toothed plate 562 drives the gear 563 meshing with it to rotate, and then the first toothed plate 561 meshing with the gear 563 also moves towards the steel strand. That is, the first toothed plate 561 drives the first column 52 connected to it and the support block 54 set on the top surface of the first column 52 to move towards the steel strand, until the two sets of support blocks 54 clamp the outer wall of the steel strand. At this time, the two sets of support blocks 54 clamp and support one end of the steel strand to be cut.

[0030] See attached document Figure 2-4 A connecting plate 6 is fixedly installed on the side of the first support column 52 and the second support column 53 away from the first toothed plate 561 and the second toothed plate 562. The other end of the connecting plate 6 is fixedly connected to one side of another set of first support columns 52 and second support columns 53. The outer wall of the main body 1 of the cutting machine is provided with a through hole 61 for limiting the sliding of the connecting plate 6. Through the connecting plate 6 and the through hole 61, when the two sets of support blocks 54 set at the first set of support boxes 51 clamp and support one end of the steel strand to be cut, the two sets of support blocks 54 set at the other set of support boxes 51 can move equally, so that the two sets of support blocks 54 set at the other set of support boxes 51 clamp and support the other end of the steel strand to be cut.

[0031] See attached document Figure 4-5 A protective component 7 is provided on one side of the support block 54. The protective component 7 includes a protective layer 71 provided on one side of the support block 54, such as a rubber pad or a wear-resistant pad, which is selected according to actual needs. The protective layer 71 increases the tightness of the connection between the support block 54 and the steel strand and extends the service life of the support block 54. A threaded rod 72 is fixedly connected to the outer wall of the protective layer 71, and a bolt 74 is used to fix the threaded rod 72 to the support block 54. The outer wall of the support block 54 is provided with a mounting hole 73 for the threaded rod 72 to be inserted. When the protective layer 71 is damaged, the bolt 74 is first rotated to loosen the connection between the threaded rod 72 and the support block 54. Then, the protective layer 71 is moved away from the support block 54 so that the threaded rod 72 at one end of the protective layer 71 is moved out of the mounting hole 73 so that the protective layer 71 can be replaced later.
