Description

Technical Field

[0001] The utility model relates to the technical field of wire shearing, in particular to a wire cutting device for construction engineering. Background Art

[0002] Steel wire is a common wire material in construction engineering, and is often used for strengthening building structures to enhance their seismic resistance and load-bearing capacity. The steel wire produced by the factory is generally coiled into a roll for convenient transportation. When taking steel wire in construction engineering, it is necessary to pull out the winding end of the steel wire from the coiled steel wire roll, and then use pliers to cut the steel wire. In order to make the subsequent construction operations such as bending, welding or connection of the cut steel wire easier, the bent steel wire will also be straightened for standby;

[0003] Although the existing mechanical devices for cutting steel wire can replace manual use of pliers to cut steel wire efficiently, after cutting a section of steel wire, it is necessary to manually assist in releasing the steel wire from the steel wire roll to the cutting device again. The feeding efficiency of the steel wire cutting device is low, and it is not conducive to straightening the steel wire for subsequent standby at the same time during the steel wire cutting process.

[0022] Compared with the prior art, the beneficial effects of the present utility model are:

[0023] 1. By fixing the steel wire coil to a plurality of clamping plates of the support mechanism, the pulled-out end of the steel wire coil sequentially passes through the positions between the first conveying rollers and the second conveying rollers and the positions between the first clamping rollers and the second clamping rollers from left to right. The first air cylinder drives the second clamping roller to move upward so that the first clamping roller and the second clamping roller cooperate to clamp and fix the steel wire. The first motor drives the lead screw to rotate, and the moving seat driven by the lead screw in a screwed transmission manner drives the first clamping roller and the second clamping roller to move to the right, facilitating pulling a certain length of steel wire from the steel wire coil to the cutting mechanism position. The second air cylinder drives the cutting knife on the cutting seat to move downward to cut the steel wire;

[0024] When the first cylinder on the traction mechanism contracts, the second clamping roller moves away from the first clamping roller, facilitating the removal of the cut wire. The lead screw rotates in the reverse direction, causing the moving seat to move the two separated first and second clamping rollers to the left end. Then, the first and second clamping rollers on the traction mechanism clamp the wire again and move to the right with the moving seat, pulling the new wire to be cut to the right. This process can be repeated multiple times to convey the wire to the right while being clamped by the first and second clamping rollers, facilitating the use of the cutting mechanism to cut long wires, thereby realizing automatic wire conveying and cutting, which is beneficial to improving the efficiency of wire cutting and conveying.

[0025] 2. A plurality of first support columns are fixed on the top surface of the machine table. A first conveying roller and a second conveying roller are rotatably arranged between two adjacent first support columns. When the traction mechanism pulls the wire through the positions between the plurality of first and second conveying rollers, the linearly arranged first and second conveying rollers are convenient for straightening the coiled wire, thereby straightening the wire while conveying it. During the process of the traction mechanism pulling the wire, the support rollers on the support mechanism can drive a plurality of clamping plates to rotate, facilitating the smooth conveyance of the coiled wire to the positions of the first and second conveying rollers.

Detailed implementation manners

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0033] Embodiment 1. Please refer to Figure 1 - Figure 5 , in the embodiment of the present utility model, a wire cutting device for construction engineering includes a machine table 100. One end of the machine table 100 is fixed with a support mechanism 200. One end of the top surface of the machine table 100 is fixed with a plurality of conveying mechanisms 300. The conveying mechanism 300 includes two first support columns 310. A first conveying roller 320 and a second conveying roller 330 are rotatably arranged between the tops of the two first support columns 310. The top surface of the machine table 100 is also fixed with a traction mechanism 400 and a cutting mechanism 500. The traction mechanism 400 includes a guide rail 410 fixedly connected to the machine table 100. Two moving seats 420 are slidably arranged inside the guide rail 410. Two second support columns 430 are fixed to the top of the moving seat 420. A first clamping roller 431 is rotatably arranged between the tops of the two second support columns 430. A U-shaped seat 440 is slidably arranged between the two second support columns 430. A second clamping roller 441 is rotatably arranged inside the U-shaped seat 440. The cutting mechanism 500 includes a U-shaped frame 510 fixedly connected to the machine table 100. Two second cylinders 520 are fixed to the top of the U-shaped frame 510. A cutting seat 530 is fixed between the output ends of the two second cylinders 520. A cutting knife 531 is fixed to the bottom end of the cutting seat 530.

[0034] Specifically, by installing the wire coil on the support mechanism 200, one end of the wire pulled out of the wire coil passes through a plurality of conveying mechanisms 300 and traction mechanisms 400 from left to right in sequence, the clamping roller 1 431 and the clamping roller 2 441 on the traction mechanism 400 are close to each other to clamp the wire, the movable seat 420 moves right with the clamping roller (including the clamping roller 1 431 and the clamping roller 2 441) to move the wire toward the cutting mechanism 500 for a distance, and then the clamping roller releases the wire and moves left with the movable seat 420, the clamping roller clamps the wire at a different position again and pulls the wire toward the cutting mechanism 500 with the movable seat 420 moving right for the second time, and the clamping roller repeatedly clamps the wire and conveys the wire The steel wire to be cut can be transported to the cutting mechanism 500, and the cylinder 2 520 moves the cutting knife 531 on the cutting seat 530 downward to automatically cut the steel wire of appropriate length. After the steel wire is cut, the left end clamping roller of the traction mechanism 400 still clamps and fixes the steel wire. At this time, the movable seat 420 can continue to move the clamping roller holding the steel wire to the right to realize automatic conveying of the steel wire for cutting and standby, eliminating the need for manual assistance to release the steel wire from the wire roll to the cutting device multiple times, which is beneficial to improving the efficiency of steel wire conveying and cutting. When the steel wire passes through multiple conveying mechanisms 300, the conveying roller 1 320 and the conveying roller 2 330 limit the conveying of the steel wire, so as to straighten the coiled steel wire at the same time.

[0035] like Figure 3 and Figure 4 As shown, in this embodiment, an annular groove 600 is formed on the outer sides of the conveying roller 1 320 and the clamping roller 1 431 , and a limiting ring 700 is sleeved and fixed on the outer sides of the conveying roller 2 330 and the clamping roller 2 441 .

[0036] In this embodiment, the steel wire is arranged between two limit rings 700. Multiple linearly arranged limit rings 700 facilitate the conveying of the steel wire along a straight line. The conveying roller 1 320 and the conveying roller 2 330 rotate in one direction to convey the steel wire, so as to straighten the steel wire during the conveying process. When the limit ring 700 on the clamping roller 2 441 is extended at the output end of the cylinder 1 421, it will be inserted into the annular groove 600 on the outside of the clamping roller 1 431, so that the limit ring 700 limits the steel wire between the clamping roller 1 431 and the clamping roller 2 441 and is clamped and fixed by the clamping roller 1 431 and the clamping roller 2 441, so that the clamping roller 1 431 and the clamping roller 2 441 can move the steel wire conveniently.

[0037] like Figure 4As shown, in this embodiment, a lead screw 411 that is rotationally connected to the moving seat 420 is rotatably disposed inside the guide rail 410. One end of the guide rail 410 is fixed with a first motor 412 capable of driving the lead screw 411 to rotate. The first motor 412 driving the lead screw 411 to rotate forward and backward can drive the moving seat 420 to slide back and forth on the guide rail 410. When sliding to the left, it is convenient for the clamping roller to move to different positions outside the steel wire. When sliding to the right, it is convenient for the clamping roller to clamp and fix the steel wire and pull the steel wire to the right.

[0038] As Figure 4 shown, in this embodiment, a first cylinder 421 capable of driving the C-shaped seat 440 to move is fixed to the top of the moving seat 420. When the output end of the first cylinder 421 extends, the C-shaped seat 440 drives the second clamping roller 441 to approach the first clamping roller 431, so that the two clamping rollers clamp and fix the steel wire. When the output end of the first cylinder 421 contracts, the C-shaped seat 440 drives the second clamping roller 441 to leave the first clamping roller 431, so that the two clamping rollers release the steel wire, which is convenient for taking the cut steel wire and also convenient for the clamping roller to move to other positions of the steel wire for clamping and standby.

[0039] As Figure 4 shown, in this embodiment, the C-shaped seat 440 is slidably connected to the second support column 430, so that the C-shaped seat 440 drives the second clamping roller 441 to move up and down stably along the second support column 430.

[0040] As Figure 1 and Figure 2 shown, in this embodiment, the support mechanism 200 includes a T-shaped beam 210 fixedly connected to one end of the machine table 100. A support roller 220 is rotatably disposed at one end of the T-shaped beam 210. A third motor capable of driving the support roller 220 to rotate is fixed to one side of the T-shaped beam 210. A plurality of telescopic members 230 are fixed to the outside of the support roller 220. A clamping plate 240 is rotatably disposed at one end of the telescopic member 230.

[0041] In this embodiment, the length of the telescopic member 230 can be adjusted so that the support roller 220 uses the clamping plate 240 to support and fix steel wire coils of different sizes. The cross section of the clamping plate 240 is arc-shaped to facilitate clamping and supporting the steel wire coil. The outer shape of the clamping plate 240 also has an arc shape to facilitate adapting to the coiled shape of the steel wire coil, so that the clamping plate 240 can clamp and fix the steel wire coil in a fitting manner. The third motor driving the support roller 220 to rotate can rotate the steel wire coil, which is convenient for the steel wire coil to actively rotate and release the steel wire, and is convenient for the traction mechanism 400 to traction the steel wire.

[0042] In this embodiment, the telescopic member 230 includes a sleeve 231 fixedly connected to the support roller 220. A screw rod 232 is screwed inside the sleeve 231, and the screw rod 232 is fixedly connected to the clamping plate 240. Rotating the nut on the screw rod 232 can cause the screw rod 232 to be screwed out or screwed into the sleeve 231, so as to adjust the length of the entire telescopic member 230 and enable the plurality of clamping plates 240 to support and fix wire coils of different sizes.

[0043] As Figure 5 shown, in this embodiment, a knife groove 511 is formed on the top surface of the C-shaped frame 510. During the downward movement of the cutting knife 531, the cutting knife 531 can move into the knife groove 511 to enable the cutting knife 531 to complete the shearing work.

[0044] Embodiment 2. On the basis of Embodiment 1, in order to eliminate the sharp burrs on the shearing end face of the steel wire while the cutting mechanism 500 cuts the steel wire, and prevent the sharp burrs from damaging the user when holding the steel wire subsequently.

[0045] As Figure 1 and Figure 5 shown, in this embodiment, a connecting seat is fixed on one side of the cutting seat 530. A grinding disc 532 is rotatably connected to the bottom end of the connecting seat through a rotating shaft. The grinding disc 532 is rotatably embedded inside the cutting seat 530. A connecting shaft is rotatably provided at the top of the cutting seat 530. Belt pulleys 533 are sleeved and fixed on the outer sides of the connecting shaft and the rotating shaft respectively. The two belt pulleys 533 are connected by a belt. A second motor 534 capable of driving the connecting shaft to rotate is fixed on one side of the cutting seat 530.

[0046] Specifically, after the cutting knife 531 cuts the steel wire, the cutting seat 530 drives the cutting knife 531 to continue moving downward, so that the grinding disc 532 moves to the cutting position. The second motor 534 drives the connecting shaft to rotate. Under the driving action of the belt pulleys 533 and the belt, the grinding disc 532 rotates, and the grinding disc 532 can grind and eliminate the sharp burrs on the shearing end face of the steel wire.
