[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] like Figure 1 As shown:

[0030] A steel strand cutting device comprises a base 1, a cutting box 2 fixedly connected to one side of the upper surface of the base 1, and a limit box 5 fixedly connected to the other side of the upper surface of the base 1.

[0031] In this embodiment: the existing disclosure (announcement) number: CN220497621U discloses a steel strand cutting device; in order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "most of the steel wires used to produce steel strands are cold-drawn high-carbon steel wires. During the process of stretching and thinning the steel strands into steel wires, tensile stress will be generated on the surface of the steel wires. The steel strands undergo elastic-plastic deformation at the moment of cutting and naturally rebound after breaking. The steel strands may rebound onto the operator, causing safety accidents." This problem is obviously a real problem that is difficult to solve. In view of this, in order to solve this technical problem, a cutting component 3 and a moving component 4 are added to the application document.

[0032] More specifically:

[0033] like Figure 1-Figure 5 As shown:

[0034] In combination with the above content, the cutting assembly 3 includes two groups of clamps 38 symmetrically slidably connected inside the limit box 5, a first spring 311 fixedly connected to the opposite sides of the two clamps 38, and two movable blocks 39 with a trapezoidal structure fixedly connected to the two groups of first springs 311 at one end away from the clamps 38, a push block 312 with a trapezoidal structure is slidably connected to one side of the limit box 5 close to the movable block 39, a first pressure plate 310 is fixedly connected to the side of the push block 312 away from the movable block 39, and a movable groove A is opened on one side of the limit box 5 close to the first pressure plate 310.

[0035] In this embodiment, when the steel strand cutting device is in use, the steel strand to be cut is first passed through the limit box 5 and the cut-off box 2, and then the cylinder 33 is started to drive the upper cutter 31 and the lower cutter 32 to cut the steel strand. During the cutting process, the lower cutter 32 drives the push block 312 to move upward through the movable rod 35, and then the inclined surface of the push block 312 squeezes the inclined surface of the movable block 39 to push the movable block 39 to move horizontally, and then the clamping plate 38 is pushed by the first spring 311, and the steel strand is clamped and limited by the two groups of clamping plates 38 to prevent sudden The stress inside the cut steel strand creates a danger, which improves the protection performance of the device. The first spring 311 is retracted and expanded, so that the clamping plate 38 can be adjusted according to the size of the steel strand to limit the steel strands of different radii. At the same time, as the push block 312 moves upward, the side of the push block 312 will conflict with the movable block 39. When it is necessary to release the limit on the steel strand, the push block 312 is driven downward by the first pressure plate 310 to release the conflict between the push block 312 and the movable block 39, thereby releasing the limit on the steel strand.

[0036] It should be noted that: the adjacent sides of the two sets of clamps 38 are fixedly connected with arc plates, and the surfaces of the arc plates are fixedly connected with rubber pads to improve the limiting effect on the steel strands; a sliding groove is opened inside the first pressure plate 310, so that when the cylinder 33 drives the lower cutting knife 32 to move downward, it will not drive the first pressure plate 310 to move downward through the movable rod 35, so as to avoid the lower cutting knife 32 driving the push block 312 to release the clamp 38 from limiting the steel strands after cutting.

[0037] Going further:

[0038] like Figure 1-Figure 5 As shown:

[0039] In order to cut the steel strands, in an optional embodiment: a cylinder 33 is installed at the bottom end of the cutting box 2, and the output end of the cylinder 33 is fixedly connected to the lower cutter 32, and two groups of movable rods 35 are symmetrically fixedly connected to the side of the surface of the lower cutter 32 close to the limit box 5, and a movable groove is provided on the side of the cutting box 2 and the limit box 5 close to the push block 312, and the end of the movable rod 35 away from the lower cutter 32 is slidably connected to the inside of the push block 312; an upper cutter 31 is arranged above the lower cutter 32, and the two sides of the upper cutter 31 are symmetrically fixedly connected to the second tooth plate 37, and the second tooth plate 37 is slidably connected to the inside of the cutting box 2, and the two sides of the lower cutter 32 are symmetrically fixedly connected to the first tooth plate 34, and the side of the cutting box 2 close to the first tooth plate 34 is rotatably connected to the gear 36, and the gear 36 is meshedly connected between the second tooth plate 37 and the first tooth plate 34.

[0040] In this embodiment: when it is necessary to cut the steel strand, the cylinder 33 is started to drive the lower cutter 32 to move upward, and then the lower cutter 32 will drive the two sets of first tooth plates 34 to move, and drive the second tooth plates 37 to move downward through the gear 36, and then drive the upper cutter 31 to move downward, and the steel strand is cut by the relative movement of the upper cutter 31 and the lower cutter 32.

[0041] It should be noted that: the upper cutter 31 and the lower cutter 32 are staggered, and the adjacent sides of the upper cutter 31 and the lower cutter 32 are both arc-shaped structures; the flatness of cutting the steel strand is improved; the upper cutter 31 is electrically connected to the external power supply through a wire.

[0042] More specifically:

[0043] like Figure 1-Figure 5 As shown:

[0044] In combination with the above content, a movable component 4 is arranged inside the limit box 5, and the movable component 4 includes a first pressure roller 43 rotatably connected to the inside of the limit box 5 and a rotating wheel 42 fixedly connected to the side of the first pressure roller 43, a fixed seat 45 is arranged below the first pressure roller 43, a second pressure roller 44 is rotatably connected to the surface of the fixed seat 45, a second spring 46 is fixedly connected between the fixed seat 45 and the limit box 5, the side of the fixed seat 45 is fixedly connected to the second pressure plate 41, and a movable groove B is opened on the side of the limit box 5 close to the second pressure plate 41.

[0045] In the present embodiment: when the steel strand cutting device is in use, the second pressure plate 41 first drives the fixing seat 45 to move downward, so that the steel strand can be passed through between the first pressure roller 43 and the second pressure roller 44, and then the second spring 46 can push the second pressure roller 44 to clamp and limit the steel strands of different radius sizes, and then the first pressure roller 43 is driven to rotate by rotating the rotating wheel 42, thereby driving the steel strand to move between the first pressure roller 43 and the second pressure roller 44, so that the position where the steel strand needs to be cut is moved to the side of the upper cutter 31, thereby improving the convenience of cutting the steel strand.

[0046] It should be noted that the surfaces of the first pressing roller 43 and the second pressing roller 44 are both arc-shaped structures.

[0047] Working principle: When the steel strand cutting device is in use, the second pressing plate 41 first drives the fixing seat 45 to move downward, so that the steel strand passes through between the first pressing roller 43 and the second pressing roller 44, and then the second spring 46 can push the second pressing roller 44 to clamp and limit the steel strands of different radius sizes, and then the first pressing roller 43 is driven to rotate by rotating the rotating wheel 42, thereby driving the steel strand to move between the first pressing roller 43 and the second pressing roller 44, so that the position where the steel strand needs to be cut off is moved to the side of the upper cutter 31, thereby improving the convenience of cutting the steel strand; then the cylinder 33 is started to drive the lower cutter 32 to move upward, and then the lower cutter 32 will drive the two sets of first tooth plates 34 to move, and drive the second tooth plates 37 to move downward through the gear 36, thereby driving the upper cutter 31 to move downward, and the upper cutter 31 and the lower cutter 32 move relative to each other to cut the steel strand. The cutting operation is performed by the lower cutting blade 32 and the lower cutting blade 32 is performed by the movable rod 35. The lower cutting blade 32 drives the pushing block 312 to move upward through the movable rod 35. Then, the inclined surface of the pushing block 312 squeezes the inclined surface of the movable block 39 and pushes the movable block 39 to move horizontally. Subsequently, the clamping plate 38 is pushed through the first spring 311. The steel strands are clamped and limited by two sets of clamping plates 38 to prevent the stress inside the steel strands that are suddenly cut from causing danger, thereby improving the protection performance of the device. Moreover, the first spring 311 is retracted to facilitate the adjustment of the clamping plate 38 according to the size of the steel strands and to limit the steel strands of different radii. At the same time, as the pushing block 312 moves upward, the side surface of the pushing block 312 will conflict with the movable block 39. When it is necessary to release the limit on the steel strand, the pushing block 312 is driven to move downward through the first pressing plate 310 to release the conflict between the pushing block 312 and the movable block 39, thereby releasing the limit on the steel strand.

[0048] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention to solve the problems raised in the above background technology.
