Description

Technical Field

[0001] The utility model relates to the technical field of steel wire cutting, in particular to an adjustable steel wire cutting device. Background Art

[0002] In construction, it is often necessary to cut rolled steel wire into small pieces of steel wire according to a certain length to meet the needs of construction. At present, automated wire cutting machines are often used to cut steel wire, which can greatly improve processing efficiency, reduce manual errors, and ensure the accuracy of the cut length of the steel wire, thereby facilitating the subsequent use and installation of the steel wire.

[0003] Chinese patent publication number CN213944699U discloses a wire cutter with a length metering device. The device feeds the wire into the cutter. When the wire slides on the support frame to the bottom of the launch plate, the wire blocks the light curtain, causing the driver to operate and the cutter body to cut, thereby achieving fixed-length cutting. The inventor found that although this method achieves fixed-length cutting of the wire, because the cutting action of the cutter body is based on the wire blocking the light curtain, the driver drives the cutter body to operate. Workers need to remove the cut steel bars in time to avoid misjudgment of the light curtain between the launch plate and the receiving plate. Therefore, each cutting requires a removal operation, which is labor-intensive. Utility Model Content

[0004] In response to the deficiencies in the prior art, the present invention provides an adjustable wire cutting device, which solves the problem in the prior art that when cutting the wire to a fixed length, workers need to remove the cut steel bars frequently in order to ensure the accuracy of the next wire cutting, resulting in high labor intensity.

[0005] The cam is fixed on the support frame, and the cam is fixed on the support frame, and the cam is fixed on the support frame, and the cam is fixed on the support frame.

[0006] Compared with the prior art, the present invention has the following beneficial effects: the steel wire is conveyed to the first cutter and the second cutter by adopting a conveying assembly, and after the end of the steel wire abuts against the rotating rod, the rotating rod is pushed to rotate, so that the rotating rod pushes the push rod to drive the connecting plate to rotate, and finally the hydraulic cylinder pushes the pressure plate downward to drive the connecting plate to move downward, so that the second cutter moves toward the first cutter to cut the steel wire, and this reciprocating process is repeated. The steel wire can be cut to a fixed length by only continuously conveying the steel wire through the conveying assembly. When it is necessary to cut steel wires of different lengths, it is only necessary to adjust the position of the assembly sleeve slider, which is very convenient. The cut steel wire will fall to the bottom plate, and the worker does not need to take the cut steel wire immediately. This part of the steel wire will not affect the subsequent cutting of the steel wire, thereby achieving fixed-distance cutting of the steel wire while significantly reducing the labor intensity of the workers.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1-4, the embodiment of the present invention proposes an adjustable wire cutting device, including a base plate 1, a support plate 2, a column 8 and a main support column. One end of the base plate 1 is provided with a conveying assembly for conveying the wire. The support plate 2 is composed of two pieces. A first cutter 3 and a second cutter 4 are fixedly provided between the two support plates 2 in the vertical direction. A reset assembly for limiting the downward sliding of the second cutter 4 is also provided on the two support plates 2. A top plate 5 is mounted on the top of the two support plates 2. A hydraulic cylinder 6 is fixed on the top plate 5. A pressure block 7 is provided vertically downward at the output end of the hydraulic cylinder 6. A core rod 9 is fixed on the top of the column 8. The core rod 9 rotates and slides A sleeve 10 is provided on the ground sleeve, a connecting plate 11 is provided on the side wall of the sleeve 10, a first spring 12 is provided between the sleeve 10 and the column 8, a support column 13 is provided on the side of the column 8 away from the conveying assembly, a mounting block 14 is horizontally mounted on the top of the support column 13, a push rod 15 is horizontally and slidably provided on the mounting block 14 through a guide rail, the push rod 15 is arranged opposite to the connecting plate 11, a slider 16 is slidably provided on the side wall of the mounting block 14, a rotating rod 17 is rotatably provided on one side of the slider 16, one end of the rotating rod 17 is rotatably connected to the push rod 15, and the mounting block 14 is also provided with an adjustment component for adjusting the position of the slider 16 on the mounting block 14.In this embodiment, the first spring 12 is a torsion spring, the first cutter 3 is fixedly arranged between the two support plates 2, the downward movement of the second cutter 4 cooperates with the first cutter 3 to cut the steel wire, and the first cutter 3 is provided with a through hole for the steel wire to pass through. When working, the steel wire is conveyed between the first cutter 3 and the second cutter 4 through the conveying assembly. When the steel wire is conveyed by the conveying mechanism, its end abuts against the rotating rod 17, the rotating rod 17 rotates, so that the rotating rod 17 drives the push rod 15 to move toward the direction of the connecting plate 11, so that the push rod 15 pushes the connecting plate 11 to rotate, so that the connecting plate 11 The connecting plate 11 is located just below the pressure block 7. The hydraulic cylinder 6 can be set to intermittent start through the PLC programmable logic controller, or a sensor can be set on the rotating rod 17. When the steel wire pushes the rotating rod 17 to rotate, the sensor transmits an electrical signal to the controller, and the controller controls the action of the hydraulic cylinder 6. Under normal circumstances, when the hydraulic cylinder 6 pushes the pressure block 7 downward, the pressure block 7 cannot contact the second cutter 4. When the connecting plate 11 rotates to the bottom of the pressure block 7, the thickness of the connecting plate 11 compensates for the distance between the first cutter 3 and the second cutter 4, so that the hydraulic cylinder 6 pushes the pressure block 7 to When the connecting plate 11 moves downward, the first cutter 3 and the second cutter 4 produce shearing, thereby cutting the steel wire. At this time, the first spring 12 is in a compressed state. After the second cutter 4 cuts the steel wire, the steel wire falls, so that the section of steel wire no longer abuts on the rotating rod 17. The first spring 12 drives the sleeve 10 to reset, so that the connecting plate 11 pushes the push rod 15 to reset, completing a wire cutting operation. This reciprocating process is repeated. When the length of the cut wire needs to be changed, the adjusting component is activated, and the adjusting component causes the slider 16 to move horizontally on the mounting block 14, thereby The movement of the slider 16 changes the position of the rotating rod 17, thereby changing the distance when the steel wire reaches the rotating rod 17 after passing the second cutter 4, and then adjusting the length of the steel wire cut each time, and at the same time extending or shortening the length of the push rod 15. In this embodiment, the push rod 15 can be composed of multiple sections of rod bodies that can be detachably connected. Since the position of the slider 16 is fixed, each section of the cut steel wire is of equal length, and the cut steel wire will fall naturally, without the need for workers to take the steel wire away each time. If necessary, a collection frame for the cut steel wire can be set on the base plate 1.

[0022] like Figure 1As shown in FIG. 3 , the adjustment assembly further includes: a first screw rod 18; a slot is provided on the side wall of the mounting block 14; a slider 16 is slidably disposed in the slot; the first screw rod 18 is horizontally and rotatably disposed in the slot; the first screw rod 18 is threadedly connected to the slider 16; a first motor 19 is fixedly disposed on the side wall of the mounting block 14; the output end of the first motor 19 is fixedly connected to one end of the first screw rod 18. When the length of the cut wire needs to be adjusted, the first motor 19 is started, and the first motor 19 drives the first screw rod 18 to rotate, so that the first screw rod 18 drives the slider 16 to move in the slot, thereby changing the distance between the rotating rod 17 and the second cutter 4. Then, the length of the push rod 15 is adjusted as needed so that the push rod 15 can always remain on one side of the connecting plate 11, thereby changing the length of the portion of the wire cut each time the second cutter 4 and the first cutter 3 cut the wire.

[0023] like Figure 2 As shown in FIG. 4 , the embodiment further includes a return block 20 and a return plate 21. The return block 20 is fixedly mounted on the top of the mounting block 14, and the return plate 21 is fixedly mounted on the outer wall of the sleeve 10. A second spring 22 is connected between the return plate 21 and the return block 20. In this embodiment, the return plate 21 is located below the connecting plate 11. When the sleeve 10 rotates, causing the connecting plate 11 to extend below the pressure block 7, the second spring 22 is in an extended state. When the push rod 15 no longer pushes the connecting plate 11, the second spring 22 pulls the connecting plate 11 back to its original position, facilitating the next cutting operation.

[0024] like Figure 5 As shown, the reset assembly further includes a third spring 23. Mounting slots are defined on opposing sides of the two mounting plates. One end of a reset block 24 is fixedly connected to each end of the second cutter 4. The other end of each reset block 24 is slidably disposed within the mounting slot. One end of the third spring 23 is connected to the reset block 24, and the other end of the third spring 23 is connected to the bottom wall of the mounting slot. Driven by the third spring 23, the second cutter 4 remains separated from the first cutter 3 and positioned directly above it. When the hydraulic cylinder 6 pushes the pressure block 7 downward, it drives the connecting plate 11 downward, causing the second cutter 4 to move downward to shear the wire. After cutting, the second cutter 4, driven by the third spring 23, moves upward to return to its original position.

[0025] like Figure 1As shown in FIG. 5 , further, the conveying assembly includes: a mounting post 25, a through slot formed on the side wall of the mounting post 25, a connecting block 26 movably provided in the through slot, a first conveying disc 27 rotatably provided on one side of the connecting block 26, a second conveying disc 28 rotatably provided on the side wall of the mounting post 25, a second motor 29 fixedly provided on the mounting post 25, an output end of the second motor 29 fixedly connected to the second conveying disc 28, and a lifting assembly provided on the mounting post 25 for adjusting the distance between the first conveying disc 27 and the second conveying disc 28. Specifically, a receiving groove is formed on the circumferential outer wall of each of the first conveying disc 27 and the second conveying disc 28 to accommodate one side of the steel wire, so that the steel wire can be accurately conveyed. When conveying the steel wire, the second motor 29 is started, and the second motor 29 drives the second conveying disc 28 to rotate, conveying the steel wire through the gap between the first conveying disc 27 and the second conveying disc 28. The first conveying disc 27 and the second conveying disc 28 can straighten the steel wire to prevent the bent steel wire end from contacting the rotating rod 17.

[0026] like Figure 3 and 5 As shown, the lifting assembly further includes: a second screw rod 30, which is vertically and rotatably disposed in the through slot, and is threadedly connected to the connecting block 26. One end of the second screw rod 30 is fixedly provided with a handle 31 after passing through the through slot. When cutting steel wires of different diameters, it is necessary to adjust the spacing between the first conveyor disc 27 and the second conveyor disc 28. At this time, the handle 31 is rotated, and the handle 31 drives the second screw rod 30 to rotate, so that the connecting block 26 threadedly connected to the second screw rod 30 is raised or lowered in the vertical direction, thereby changing the spacing between the first conveyor disc 27 and the second conveyor disc 28 to accommodate steel wires of different diameters.

[0027] like Figure 1 and 3 As shown, further, an arcuate notch is provided on the end of the rotating rod 17 away from the push rod 15. The arcuate notch is provided on the rotating rod 17 so that the steel wire can be stably pushed to rotate after being abutted on the rotating rod 17.

[0028] like Figure 3 As shown, the invention further includes a bracket 32, a curved plate 33 is provided on the top of the bracket 32, and a curved groove is provided on the top of the curved plate 33. The curved plate 33 supports the steel wire when it enters between the first cutter 3 and the second cutter 4, thereby preventing the steel wire from being skewed and allowing the steel wire to enter between the first cutter 3 and the second cutter 4 smoothly.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
