[0020] In this technical solution, the mounting ring 110 and the mounting plate 111 are used to provide mounting points for the installation of various parts, the motor 120 is used to drive the cutting disc 121 to rotate and cut the steel bars, and the guide column 130 and the connecting ring 131 are used to limit the movement of the first sleeve 210 and the second sleeve 220.

[0021] A plurality of push devices 200 are distributed in an annular manner outside the cutting disk 121. The push device 200 includes a first sleeve 210, a second sleeve 220, a second electric push rod 230, and a third electric push rod 240. The second electric push rod 230 and the third electric push rod 240 are fixed to the inner wall of the mounting ring 110 by bolts. The first sleeve 210 and the second sleeve 220 are symmetrically distributed on both sides of the cutting disk 121. The second electric push rod 230 is connected to the first sleeve 210 and the second sleeve 220 by a connecting frame 231. The connecting frame 231 is a U-shaped structure. The top of the connecting frame 231 is connected to the moving end of the second electric push rod 230, and the two ends of the connecting frame 231 are respectively welded to the first sleeve 210 and the second sleeve 220. The first sleeve 210 and the second sleeve 220 are respectively slidably connected to the guide column 130 through the slider 132. The outer walls of the first sleeve 210 and the second sleeve 220 are respectively provided with a socket, and the socket is slidably connected with an extrusion block 241. The extrusion block 241 is fixed to the moving end of the third electric push rod 240 by bolts;

[0022] In this technical solution, the interior of the first sleeve 210 and the second sleeve 220 is used to install steel bars, the second electric push rod 230 and the connecting frame 231 are used to push the first sleeve 210 and the second sleeve 220, so that the cutting disk 121 is placed in the middle of the first sleeve 210 and the second sleeve 220 to complete the cutting of the steel bars, and the third electric push rod 240 and the extrusion block 241 apply pressure to the steel bars inside the first sleeve 210 and the second sleeve 220 to fix them.

[0023] In some technical solutions, reference Figure 1 , Figure 3 and Figure 4 The inner wall of the mounting ring 110 is installed with a first electric push rod 140 through a connecting rod, the connecting rod is welded to the inner wall of the mounting ring 110, the fixed end of the first electric push rod 140 is fixed to the connecting rod by bolts, the movable end of the first electric push rod 140 is fixed with a guide ring 141 by bolts, the guide ring 141 is a trumpet-shaped structure, the discharge port of the guide ring 141 is connected to the first sleeve 210, the guide ring 141 includes two half rings, the two half rings are connected to the mounting seat by a torsion spring, the mounting seat is fixedly connected to the first electric push rod 140 by bolts, and the torsion spring is installed at the connection between the first electric push rod 140 and the mounting seat.

[0024] In this technical solution, the first electric push rod 140 is used to push the guide ring 141 to move toward the pushing device 200, and the smaller through hole in the guide ring 141 is aligned with the entrance of the first sleeve 210, so that the steel bars passing through the second sleeve 220 can be inserted into the interior of the first sleeve 210 along the inner cavity of the guide ring 141, so as to quickly complete the steel bars passing through the inner cavities of the first sleeve 210 and the second sleeve 220.

[0025] In some technical solutions, reference Figure 1-2 A mounting hole is opened on the outer wall of the first sleeve 210, and the mounting hole is located below the first sleeve 210. A rotating plate 211 is rotatably connected to the mounting hole through a rotating shaft. A fourth electric push rod 250 is distributed outside the first sleeve 210, and both ends of the fourth electric push rod 250 are respectively connected to the first sleeve 210 and the rotating plate 211 through a rotating seat.

[0026] In this technical solution, the use of the fourth electric push rod 250 can control the rotation of the rotating plate 211, so that the rotating plate 211 overlaps with the first sleeve 210 or maintains an angle. Before the steel bar is cut, the rotating plate 211 and the first sleeve 210 remain overlapped, and after the steel bar is cut, the fourth electric push rod 250 contracts to create an angle between the rotating plate 211 and the first sleeve 210, so that the cut steel bar slides from the inner cavity of the first sleeve 210 along the rotating plate 211, thereby completing the unloading.

[0027] In some technical solutions, reference Figure 2 A side plate 242 is welded to the top of the extrusion block 241, and the side plate 242 is in sliding contact with the inner wall of the socket.

[0028] In this technical solution, the use of the side plate 242 can ensure that the top of the third electric push rod 240 is always aligned with the socket, preventing the extrusion block 241 from being misaligned with the socket when moving, making it difficult to move the extrusion block 241 out of the socket.

[0029] In some technical solutions, reference Figure 1 and Figure 3 A guide groove is formed on the outer wall of the guide column 130, and the slider 132 is slidably connected to the guide groove.

[0030] In this technical solution, the sliding connection using the guide groove and the slider 132 can limit the movement state of the first sleeve 210 and the second sleeve 220, so that the movement posture of the first sleeve 210 and the second sleeve 220 always points to the center of the cutting disk 121.

[0031] The number of the pushing devices 200 installed inside the mounting ring 110 can be increased or decreased according to actual usage requirements.

[0032] Working principle: connect the motor 120, the second electric push rod 230, the third electric push rod 240, the fourth electric push rod 250, and the first electric push rod 140 to the external power supply and control switch. In the initial state, the first electric push rod 140 pushes the guide ring 141 to move and dock with the first sleeve 210. At this time, the steel bar is inserted into the second sleeve 220 through the guide ring 141. Then the first electric push rod 140 contracts to drive the guide ring 141 to separate from the steel bar. At this time, the third electric push rod 240 pushes the extrusion block 241 to move toward the center of the cutting disk 121, and the steel bar is firmly fixed on the inner wall of the first sleeve 210 and the second sleeve 220. Turn on the control switch of the motor 120, and the motor 120 drives the cutting disk 121 to rotate at high speed. At this time, operate the second electric push rod 230 and The control switch of the third electric push rod 240 allows the second electric push rod 230 and the third electric push rod 240 to work synchronously. The second electric push rod 230 pushes the first sleeve 210 and the second sleeve 220 to move as a whole through the connecting frame 231. When the first sleeve 210 and the second sleeve 220 are moving, the third electric push rod 240 and the extrusion block 241 can always apply pressure to the steel bar, and the steel bar contacts with the cutting disk 121 to complete the cutting until it is separated. At this time, the third electric push rod 240 and the fourth electric push rod 250 shrink synchronously, so that the extrusion block 241 is separated from the steel bar, and the rotating plate 211 forms an angle with the first sleeve 210, so that the cut steel bar slides along the rotating plate 211 to complete the falling. According to the above steps, multiple steel bars can be cut synchronously to improve the cutting efficiency of the steel bars.
