DETAILED DESCRIPTION

[0030] 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.

[0031] See also Figures 1 to 7 , the utility model provides a technical solution:

[0032] The twisted steel straightening and cutting machine based on servo cam shearing comprises a workbench 1, a processing mechanism 2 for modulating and cutting steel bars is arranged on the top of the workbench 1, and an adjusting component 3 for adjusting steel bars of different diameters is arranged inside the processing mechanism 2;

[0033] The processing mechanism 2 includes a box 201, a first motor 202, a traction roller 203, a driven roller 204, a support portion 205, a straightening cylinder 206, a cutting box 207, a round hole 208, a round plate 209, a round rod 210, a connecting plate 211, a movable knife 212, a slide rail 213 and a slider 214. The box 201 is bolted to the top of the workbench 1, the first motor 202 is bolted to the inside of the box 201, the traction roller 203 is fixedly connected to the output end of the first motor 202, the driven roller 204 is rotatably connected to the inside of the box 201, and the support portion 205 is bolted to the workbench. 1, the straightening cylinder 206 is rotatably connected to the inside of the supporting portion 205, the cutting box 207 is bolted to the top of the workbench 1, the round hole 208 is opened in the cutting box 207, the round plate 209 is rotatably connected to the inner wall of the cutting box 207, the round rod 210 is rotatably connected to the side wall of the round plate 209, the connecting plate 211 is hinged to the outer wall of the round rod 210, the moving knife 212 is hinged to one end of the connecting plate 211, the slide rail 213 is welded to the inside of the cutting box 207, the slider 214 is welded to the top of the moving knife 212, and the slider 214 is slidably connected to the slide rail 213.

[0034] Specifically, Figure 6 As shown, a first pulley 4 is welded on the side wall of the straightening cylinder 206 , a second motor 5 is bolted inside the workbench 1 , a second pulley 6 is fixedly connected to the output end of the second motor 5 , and a belt 7 is arranged outside the first pulley 4 .

[0035] Specifically, Figure 1 As shown, a plurality of switch doors 8 are hinged on the outer wall of the workbench 1 for facilitating the inspection and maintenance of the electrical equipment inside the workbench 1 .

[0036] Specifically, Figure 1 As shown, a plurality of heat dissipation slots 9 are provided on the side wall of the switch door 8 for dissipating heat from the electrical equipment inside the workbench 1 , and the number of the heat dissipation slots 9 is several and evenly distributed.

[0037] Specifically, Figure 4 As shown, a mounting plate 10 is welded on the outer wall of the workbench 1, a screw groove 11 is opened inside the mounting plate 10, and the number of the mounting plates 10 is four and they are evenly distributed.

[0038] Specifically, Figure 6 As shown, a guide portion 14 for guiding the steel bars is bolted to the side wall of the cutting box 207 , and the guide portion 14 is connected to the circular hole 208 .

[0039] When in use, one end of the steel bar is placed between the traction roller 203 and the driven roller 204, and then the first motor 202 is started. The first motor 202 drives the traction roller 203 to rotate. At this time, the steel bar will be clamped by the traction roller 203 and the driven roller 204 and then the steel bar is pulled and then moved. Then the second motor 5 is started, and the second motor 5 drives the second pulley 6. The second pulley 6 drives the first pulley 4 and the straightening cylinder 206 to rotate through the belt 7. The straightening cylinder 206 rotates at a high speed. The steel bar passing through the straightening cylinder 206 is straightened during the rotation process, and the rust on the surface of the steel bar is removed by the straightening mold. Then the straightened steel bar continues to move, and the guide part 14 guides to the inside of the circular hole 208, and then the circular plate 209 is driven to rotate by an external servo motor. Because the round rod 210 is eccentrically arranged, when the circular plate 209 rotates, it will drive the connecting plate 211 and the moving knife 212 to move, thereby cutting the steel bar inside the circular hole 208. Every time the circular plate 209 rotates one circle, the length of the cut steel bar will be the same, and the accuracy is high.

[0040] Specifically, Figure 3 As shown, the adjustment component 3 includes a screw rod 301, a rotating part 302 and a sleeve 303. The screw rod 301 is threadedly connected to the inside of the box body 201, the rotating part 302 is welded to the top of the screw rod 301, the sleeve 303 is rotatably connected to the outer wall of the driven roller 204, and the bottom of the screw rod 301 is rotatably connected to the outer wall of the sleeve 303.

[0041] Specifically, Figure 4 As shown, the external thread of the screw rod 301 is connected with a nut 12 , and an inclined rod 13 is welded on the outer wall of the nut 12 for facilitating the rotation of the nut 12 .

[0042] When straightening steel bars of different diameters, the screw rod 301 can be rotated so that the screw rod 301 drives the sleeve 303 and the driven roller 204 inside the sleeve 303 to rise, thereby adjusting the distance between the driven roller 204 and the traction roller 203. After the adjustment is completed, the user rotates the nut 12 through the inclined rod 13, so that the nut 12 fixes the screw rod 301 to prevent the screw rod 301 from rotating.

[0043] By adopting the above technical solution, the problem of errors in cutting the steel bars caused by the existing twisted steel straightening and cutting machine based on servo cam shearing using a plurality of sets of springs to cooperate in cutting the steel bars is solved. When the springs are stretched or contracted, the elastic force of the springs will cause the slider 214 to shake continuously, thereby causing errors in cutting the steel bars.

[0044] Working principle: When in use, the first motor 202 and the second motor 5 are connected to an external power source, and then one end of the steel bar is placed between the traction roller 203 and the driven roller 204, and then the first motor 202 is started, and the first motor 202 drives the traction roller 203 to rotate. At this time, the steel bar will be clamped by the traction roller 203 and the driven roller 204 and then the steel bar is pulled, and then moved, and then the second motor 5 is started, and the second motor 5 drives the second pulley 6, and the second pulley 6 drives the first pulley 4 and the straightening cylinder 206 to rotate through the belt 7. The straightening cylinder 206 rotates at a high speed, and the steel bar passing through the straightening cylinder 206 is straightened during the rotation process, and the rust on the surface of the steel bar is removed by the straightening mold, and then the straightened steel bar continues to move, and the guide part 14 guides it to the round hole 208, and then the circular plate 209 is driven to rotate by an external servo motor. Because the round rod 210 is eccentrically arranged, when the circular plate 209 rotates, it will drive the connecting plate 211 and the movable knife 212 to move, thereby cutting the steel bars inside the circular hole 208. Every time the circular plate 209 rotates one circle, the length of the cut steel bars will be the same, and the accuracy is high. When straightening steel bars with different diameters, the screw rod 301 can be rotated to make the screw rod 301 drive the sleeve 303 and the driven roller 204 inside the sleeve 303 to rise, thereby adjusting the distance between the driven roller 204 and the traction roller 203. After the adjustment is completed, the user rotates the nut 12 through the inclined rod 13, so that the nut 12 fixes the screw rod 301 to prevent the screw rod 301 from rotating.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
