Description

Technical Field

[0001] The present invention relates to the technical field of steel strand cutting, and specifically refers to a steel strand cutting device. Background Art

[0002] Most steel strand cutting devices adopt a circumferential cutting method. The existing circumferential cutting method cutting device is composed of a shell, a disc with a central circular hole, a circumferential cutting device, and a driving device. The motor drives the disc to rotate through a crawler and a rotating shaft. The rotation of the disc makes the blade rotate at a high speed. The electric shrinker shrinks the circular iron sheet and pushes the control rod to make the blade move from the outside to the inside to cut the steel strand. This device is mostly used for cutting relatively thick steel strands, with neat cut surfaces, and is suitable for scenarios with high requirements for cutting quality;

[0003] However, in this cutting method, during the cutting process, after multiple strands are cut off, the steel strand to be cut becomes thinner. If the circumferential cutting device maintains a constant moving speed, it is easy to make the cut surface of the steel strand uneven. Therefore, it is necessary to decelerate the cutter during the circumferential cutting process. And when cutting the steel strand, it is necessary to cooperate with a propulsion device to send the steel strand in front of the cutting tool, and then use an automatic fixture to clamp one end before cutting can be carried out, resulting in a high cost.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Combined with the attached Figure 1 and the attached Figure 3 and the attached Figure 4 : A steel strand cutting device, which includes a device frame 1. A through slot 2 is provided on one side of the device frame 1. A cutting saw 3 that can move along the through slot is provided inside the device frame 1. A control component 7 that can drive the cutting saw 3 to move in multiple directions and control the moving speed is provided inside the device frame 1. The control component 7 includes an L-shaped frame body 701. The device frame 1 includes a rectangular frame body 101. A rotating shaft 702 rotatably connected to the rectangular frame body 101 is provided on the side of the L-shaped frame body 701 close to the through slot 2. A slide shaft 703 slidably connected to the rectangular frame body 101 is provided at the bend of the L-shaped frame body 701. First arc-shaped chutes 103 for the slide shaft 703 to slide are provided at the upper and lower ends of the rectangular frame body 101.

[0031] Both ends of the sliding shaft 703 exposed from the rectangular frame body 101 are respectively rotatably connected with an arc-shaped rack 713 and an arc-shaped sliding bar 714. One end of the rectangular frame body 101 is rotatably connected with a gear 712 for the arc-shaped rack 713 to move. On the side of the arc-shaped rack 713 away from the gear 712, there is an arc-shaped limiting bar 102 fixedly installed on the rectangular frame body 101. The other end of the rectangular frame body 101 is provided with an arc-shaped limiting rail 104 fixedly installed on the rectangular frame body 101 for the arc-shaped sliding bar 714 to move. On the rectangular frame body 101, there is a first driving motor 711 for the gear 712 to rotate.

[0032] With this structure, when the first driving motor 711 is started, the arc-shaped rack 713 is driven by the gear 712 to move along the arc-shaped limiting bar 102, so that the arc-shaped sliding bar 714 moves along the arc-shaped limiting rail 104. Furthermore, the sliding shaft 703 and the L-shaped frame body 701 rotate around the connection point between the L-shaped frame body 701 and the rectangular frame body 101 as the axis and move along the first arc-shaped chute 103, thereby the cutting angle of the cutting saw 3 can be adjusted.

[0033] Combined with attached Figure 1 、attached Figure 3 、attached Figure 4 and attached Figure 5 :

[0034] One end of the L-shaped frame body 701 away from the through slot 2 is rotatably connected with a plate body 705. At the bottom end of the plate body 705, a second driving motor 706 is fixedly installed. At the top end of the plate body 705, a driven shaft 708 is rotatably connected. On the side of the L-shaped frame body 701 close to the through slot 2, there is a second arc-shaped through slot 710 for the driven shaft 708 to move. The driven shaft 708 passes through one end of the L-shaped frame body 701 and is fixedly connected with the cutting saw 3. A belt pulley transmission assembly 709 is arranged between the driven shaft 708 and the driving shaft of the second driving motor 706;

[0035] Inside the L-shaped frame body 701, there is a first strip-shaped slot 719. Inside the first strip-shaped slot 719, a first threaded rod 721 is rotatably connected. A first shaft bracket 720 that can move inside the first strip-shaped slot 719 is threadedly connected to the first threaded rod 721. One end of the L-shaped frame body 701 is provided with a third driving motor 723 for the first threaded rod 721 to rotate. Inside the plate body 705, there is a second strip-shaped slot 715. Inside the second strip-shaped slot 715, a second threaded rod 716 is rotatably connected. A second shaft bracket 717 that can move inside the second strip-shaped slot 715 is threadedly connected to the second threaded rod 716. A connecting rod 722 is rotatably connected between the first shaft bracket 720 and the second shaft bracket 717. One end of the plate body 705 is provided with a fourth driving motor 718 for the second threaded rod 716 to rotate.

[0036] By means of the above structure, the third drive motor 723 is started to control the first shaft bracket 720 to move along the first threaded rod 721, and the fourth drive motor 718 is controlled to control the second shaft bracket 717 to move along the second threaded rod 716;

[0037] When the first threaded rod 721 and the second threaded rod 716 rotate in opposite directions, the plate body 705 rotates at an accelerated speed, thereby controlling the circumferential cutting speed of the cutting saw 3;

[0038] When the first threaded rod 721 and the second threaded rod 716 rotate in the same direction and the rotation speed of the first threaded rod 721 is less than that of the second threaded rod 716, the rotational acceleration of the plate body 705 increases, thereby controlling the circumferential cutting speed of the cutting saw 3;

[0039] When the first threaded rod 721 and the second threaded rod 716 rotate in the same direction and the rotation speed of the first threaded rod 721 is greater than that of the second threaded rod 716, the rotational acceleration of the plate body 705 decreases, thereby controlling the circumferential cutting speed of the cutting saw 3.

[0040] Combined with attached Figure 2 、attached Figure 6 、attached Figure 7 、attached Figure 8 、attached Figure 9 and attached Figure 10 :

[0041] Support frames 4 are provided on both sides of the through groove 2. A pushing assembly 5 for pushing the steel strand to move and having a clamping function is provided on the support frame 4. An intermittent power assembly 6 for providing power for the pushing assembly 5 is provided below the pushing assembly 5. The pushing assembly 5 includes a slide rail frame 501 fixedly installed on the support frame 4. A fixed sleeve body 502 is provided at one end of the slide rail frame 501. A movable sleeve body 503 that can move within the slide rail frame 501 is provided inside the slide rail frame 501. Clamping assemblies 504 for moving the steel strand unidirectionally are provided inside both the fixed sleeve body 502 and the movable sleeve body 503;

[0042] Conical through grooves 507 are provided inside both the fixed sleeve body 502 and the movable sleeve body 503. The clamping assembly 504 includes a threaded sleeve 5041 threadedly connected to the conical through groove 507. A cylinder body 5049 is slidably connected inside the threaded sleeve 5041. A limiting ring 5042 that cooperates with the threaded sleeve 5041 is provided at one end of the cylinder body 5049, and a conical sleeve body 5043 located inside the conical through groove 507 is provided at the other end. A first spring 5048 sleeved outside the cylinder body 5049 is provided between the conical sleeve body 5043 and the threaded sleeve 5041. A number of uniformly distributed spherical through grooves 5046 are uniformly distributed inside the conical sleeve body 5043, and spheres 5047 are rotatably connected inside the spherical through grooves 5046;

[0043] A second spring 506 is provided between the fixed sleeve body 502 and the movable sleeve body 503. A toothed plate 505 is provided at the bottom of the movable sleeve body 503. The intermittent power assembly 6 includes a semi-toothed gear 601 rotatably mounted in the support frame 4. The semi-toothed gear 601 contacts the toothed plate 505. A fifth drive motor 602 for rotating the semi-toothed gear 601 is provided on the support frame 4.

[0044] With the above structure, the steel strand passes through the clamping assembly 504 in the fixed sleeve body 502 of the left pushing assembly 5, then passes through the clamping assembly 504 in the movable sleeve body 503 of the left pushing assembly 5, and then passes through the clamping assembly 504 in the fixed sleeve body 502 of the right pushing assembly 5, and then passes through the clamping assembly 504 in the movable sleeve body 503 of the right pushing assembly 5. A rope hole 5045 for the steel strand to pass through is provided in the limiting ring 5042 and the frustum-shaped sleeve body 5043. At this time, the two fifth drive motors 602 are synchronously started, and the two toothed plates 505 are driven by the semi-toothed gear 601 to make intermittent movements, so as to drive the two movable sleeve bodies 503 to intermittently move towards the fixed sleeve body 502 respectively. During the movement process, see attached Figure 8 and attached Figure 9 , when the movable sleeve body 503 moves towards the fixed sleeve body 502, the sphere 5047 rolls friction with the steel strand. The movable sleeve body 503 drives the threaded sleeve 5041 to move towards the fixed sleeve body 502. At this time, the steel strand does not move;

[0045] When the movable sleeve body 503 moves in a direction away from the fixed sleeve body 502, the movable sleeve body 503 drives the threaded sleeve 5041 to move in a direction away from the fixed sleeve body 502. The sphere 5047 rolls friction with the steel strand. The rolling friction overcomes the pre-tension of the first spring 5048, causing the cylinder body 5049 to move relative to the threaded sleeve 5041, so that the frustum-shaped sleeve body 5043 contacts the inner wall slope of the frustum-shaped through groove 507, and further increasing the pressure between the sphere 5047 and the steel strand, changing from rolling friction to sliding friction, so as to move the steel strand;

[0046] Since the entire steel strand is located on a wire roller (not shown in the figure) and needs to be driven by a driving device to rotate (not shown in the figure), this is the prior art and will not be elaborated here. Therefore, only one end of the steel strand needs to be fixed. When the cutting saw 3 cuts the steel strand, the two ends of the cutting point are stressed. One end is restricted by the wire roller, and the other end is clamped by the clamping assembly 504 of the right pushing assembly 5. The clamping principle is the same as above.

[0047] In the specific implementation of the present invention, the steel strand is passed through the pushing components 5 on the left and right sides, the intermittent power component 6 is started, so that the steel strand moves within the pushing components 5 on the left and right sides. When the required length is reached, the second driving motor 706 is started to drive the cutting saw 3 to rotate. The cutting angle is adjusted by controlling the first driving motor 711, and the acceleration of the circumferential movement of the cutting saw 3 is adjusted by controlling the third driving motor 723 and the fourth driving motor 718.

[0048] The present invention and its implementation manners have been described above. Such description is not restrictive, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the gist of the present invention, they shall fall within the protection scope of the present invention.
