[0020] like Figures 1-2As shown, the utility model is a fixed-length cutting device for steel bars, comprising a fixed plate 1, and a driving device 2 for driving the steel bars to move is connected to the upper part of the fixed plate 1. The driving device 2 comprises: a fixed frame 21, a first motor 29, a rotating block 22, a threaded rod 23, a rotating rod 24, an extrusion block 25, a retaining ring 27, an arc ring 26 and a rotating wheel 28. The fixed frame 21 is fixedly connected to the upper part of the fixed plate 1, the first motor 29 is fixedly connected to the lower part of the fixed frame 21, the output shaft of the first motor 29 passes through the fixed frame 21 and is fixedly connected to the rotating wheel 28, and the rotating wheel 28 is driven to rotate by the first motor 29, and the rotating wheel 28 can drive the steel bars to move. A through slot 3 is opened through the upper part of the fixed frame 21, one end of the threaded rod 23 passes through the through slot 3 and is slidably connected to the through slot 3, and the threaded rod 23 is used to drive the arc ring 26 and other components to move. One end of the threaded rod 23 is threadedly connected with the rotating block 22, and the rotating block 22 is located outside the fixed frame 21. By rotating the rotating block 22, the rotating block 22 is pressed against the outside of the fixed frame 21 to prevent the threaded rod 23 from rising and falling. The threaded rod 23 is rotatably connected with the rotating rod 24, and the rotating rod 24 passes through the extrusion block 25 and is fixedly connected with the extrusion block 25. The rotating rod 24 passes through the arc ring 26 and is fixedly connected with the arc ring 26, and the arc ring 26 is used to prevent the steel bar from moving. The retaining ring 27 has two pieces respectively arranged on both sides of the arc ring 26, and the retaining ring 27 is used to prevent the steel bar from sliding out of the groove 4. The extrusion block 25 has two pieces respectively arranged on both sides of the retaining ring 27, and the extrusion block 25 is used to prevent the retaining ring 27 from sliding. A groove 4 is opened in the middle of the rotating wheel 28, and the groove 4 is used to place the steel bar.
[0021] like Figures 1-2As shown, the length of the arc ring 26 is adapted to the groove 4, and the arc ring 26 and the retaining ring 27 can be extended into the groove 4, so that steel bars of different sizes can be clamped. The fixing plate 1 is slidably connected to the fixing rods 5 on both sides, and the upper side of the fixing plate 1 is provided with a slide groove 13. The bottom end of the fixing rod 5 is slidably connected to the slide groove 13, and the distance of the cutting device 6 is adjusted by moving the fixing rod 5. The bottom end of the fixing rod 5 is connected to the fixing block 15, and the fixing block 15 has two blocks respectively arranged on both sides of the fixing rod 5. The fixing block 15 is used to stop the fixing rod 5 and prevent the fixing rod 5 from moving. The fixing block 15 close to the cutting wheel 66 is fixedly connected to the fixing rod 5, and the other fixing block 15 is slidably connected to the fixing rod 5. A spring 14 is connected between the two fixing blocks 15, and the spring 14 is used to push the fixing block 15 to contact the slide groove 13. A sliding rod 7 is connected between the two fixing rods 5, and the sliding rod 7 is penetrated by a clamping plate 8, and the two fixing rods 5 are moved synchronously by the sliding rod 7. The height of the arc ring 26 is higher than the height of the sliding rod 7, which facilitates the movement of the steel bar to the upper part of the sliding rod 7. Bolts 11 are threadedly connected between the clamping plates 8, and a push block 12 is threadedly connected to the outer side of the bolt 11. The clamping plates 8 are retracted to clamp the steel bar by rotating the push block 12. A cutting device 6 for cutting the steel bar is connected to one side of the fixing rod 5. A telescopic rod 16 is connected to the upper part of the fixing plate 1 to prevent the steel bar from falling on the ground and being difficult to pick up. A placement plate 17 is connected to the upper end of the telescopic rod 16. A guardrail 9 is connected to the side of the placement plate 17.
[0022] like Figures 1-2 As shown, the cutting device 6 includes: a first rotating shaft 61, a rotating rod 62, a second motor 63, a first rotating disk 64, a second rotating disk 65, a second rotating shaft 67 and a cutting wheel 66. The first rotating shaft 61 is fixedly connected to the fixed rod 5, and the second motor 63 is fixedly connected to the first rotating shaft 61. The first rotating shaft 61 passes through the rotating rod 62 and is rotatably connected to the rotating rod 62. The output shaft of the second motor 63 is fixedly connected to the first rotating disk 64, and the second motor 63 drives the first rotating disk 64 to rotate. The second rotating shaft 67 passes through the rotating rod 62 and is rotatably connected to the rotating rod 62. One end of the second rotating shaft 67 is fixedly connected to the second rotating disk 65. A belt 10 is connected between the first rotating disk 64 and the second rotating disk 65, so that the second rotating disk 65 rotates synchronously with the first rotating disk 64. The other end of the second rotating shaft 67 is fixedly connected to the cutting wheel 66, and the second rotating disk 65 drives the cutting wheel 66 to rotate.
[0023] The working process of the above scheme is as follows: when the steel bar is to be cut, the steel bar is placed on the groove 4, and the rotating block 22 is rotated so that the rotating block 22 no longer conflicts with the fixed frame 21. The threaded rod 23 is moved to move the arc ring 26 until the arc ring 26 fits the steel bar, and the rotating block 22 is rotated to conflict with the fixed frame 21 to fix the spacing of the threaded rod 23. At this time, the first motor 29 is started to drive the rotating wheel 28 to rotate, and the rotating wheel 28 drives the steel bar to move, so that the steel bar moves to the middle of the clamping plate 8 on the upper part of the sliding rod 7. At this time, the pushing block 12 is rotated to close the clamping block to close the steel bar to prevent the steel bar from being scattered. At this time, the steel bar continues to move. When it moves to the appropriate position and needs to be cut, the rotating rod 62 is rotated, and the second motor 63 is started to drive the cutting wheel 66 to rotate to cut the steel bar. The cut steel bar falls onto the placement plate 17. When the length of the cut steel bar needs to be adjusted, the fixed block 15 is pushed so that the fixed block 15 no longer conflicts with the slide groove 13, and the fixed rod 5 is moved to adjust the spacing between the cutting wheel 66 and the rotating wheel 28.
[0024] The above scheme has the following beneficial effects: the driving device 2 can be used to clamp and transport steel bars of different sizes; the threaded rod 23 drives the arc ring 26 to descend to fix and resist the steel bars in the groove 4, so that the steel bars can only move in the groove 4, and the retaining ring 27 can prevent the steel bars from slipping out of the groove 4, and the retaining ring 27 can be squeezed and pressed against the arc ring 26 by the extrusion block 25; the cutting length of the steel bars is controlled by the cutting device 6; the length of the steel bars cut by the cutting wheel 66 is controlled by moving the fixing rod 5; the distance of the fixing rod 5 is adjusted by the fixing block 15; the steel bars can be clamped and fixed by the clamping plate 8 to prevent the steel bars from shaking during cutting.
