The external thread of the reciprocating screw rod 141 is connected to a moving seat 143, and the top of the moving seat 143 is fixed with a second limiting plate 142 by bolts. The two second motors 14 are located at the bottom of the mounting frame 13 and are distributed on both sides of the cutting blade 121.

[0022] The mounting seat 1, the vertical plate 11 and the mounting frame 13 are used to provide mounting points for the installation of various parts. 120 and the cutting blade 121 cooperate with each other to form a cutting mechanism for cutting the steel bars. The second motor 14 and the reciprocating screw rod 141 are used together to drive the moving seat 143 and the second limit plate 142 to move in a straight line along the mounting frame 13 to drive the steel bars to move toward the cutting blade 121.

[0023] Embodiment 2: The pushing device 2 includes a third motor 21, a rotating frame 22, an electric push rod 23 and a moving rod 24. The third motor 21 is connected to the outer wall of the mounting frame 13 through a connecting seat, and the connecting seat is welded to the outer wall of the mounting frame 13. The third motor 21 is fixed to the U-shaped groove at the top of the connecting seat by bolts.

[0024] The third motor 21 is used to drive the rotating frame 22 to rotate with the rotating seat as the center, and the electric push rod 23 is used to drive the moving rod 24 to move linearly along the inner wall of the rotating frame 22. When the rotating frame 22 is in a horizontal state, the movement of the moving rod 24 can drive the clamping rod 241 to clamp the steel bar, so that the moving rod 24, the clamping rod 241 and the second limit plate 142 form a clamping cavity.

[0025] Embodiment 3: The mounting frame 13 is a U-shaped structure. The top of the mounting frame 13 is located on both sides of the cutting piece 121, and two first limit plates 131 are welded respectively. A gap is left between the two first limit plates 131. The clamping rod 241 can slide in contact with the first limit plate 131 through the gap. A clamping block 242 is welded to the outer wall of the clamping rod 241. The arc centers of the clamping block 242, the second limit plate 142 and the first limit plate 131 coincide with each other. When the steel bars are installed in the initial state, the steel bars can be placed in the U-shaped groove formed by the second limit plate 142 and the first limit plate 131. When the steel bars need to be clamped, the clamping rod 241 passes through the gap as the moving rod 24 moves, so that the clamping block 242 contacts with the upper part of the outer wall of the steel bars. At this time, the clamping of the steel bars can be completed.

[0026] A guide hole 133 is opened inside the mounting frame 13, and a guide bar 144 is fixed to the outer wall of the second limiting plate 142 by bolts, and a sliding groove is opened on the inner wall of the guide hole 133 to be slidably connected to the guide bar 144; the sliding of the guide bar 144 along the sliding groove can prevent the second limiting plate 142 from shaking when moving in a straight line along the mounting frame 13, so that it can move in a straight line stably and make the steel bar contact with the cutting blade 121 to complete the cutting.

[0027] A transverse plate 15 is welded to the outer wall of the mounting frame 13, and scale lines may be provided on the surface of the transverse plate 15, and a baffle 151 is slidably sleeved on the outside of the transverse plate 15, and a screw is connected to the external thread of the baffle 151. When locking the baffle 151, the screw is rotated so that the end of the screw contacts the transverse plate 15, and the locking of the baffle 151 is completed; according to the cutting size requirements of the steel bars, the baffle 151 can be pushed to move on the transverse plate 15 and positioned with bolts, and subsequently, only a thrust needs to be applied to the steel bars so that the end of the steel bars contacts the surface of the baffle 151.

[0028] The rotating frame 22 is a U-shaped structure, and a guide groove 221 is opened on the inner side wall of the rotating frame 22. A moving block 243 which is slidably connected to the guide groove 221 is welded on the outer side wall of the moving rod 24. The connecting frame is a U-shaped structure. The guide groove 221 and the moving block 243 can be used to control the moving trajectory of the moving rod 24, so that the moving rod 24 can always move in a straight line with the rotating frame 22, thereby preventing the end of the moving rod 24 away from the rotating frame 22 from falling when the rotating frame 22 is tilted, thereby affecting the use.

[0029] Working principle: The first motor 12, the electric push rod 23, the third motor 21, and the second motor 14 are connected to an external power supply and control device. When the steel bar needs to be cut, the baffle 151 is first pushed to move on the horizontal plate 15 and locked with a screw. In the initial state, the third motor 21 drives the rotating frame 22 to rotate, so that an angle is generated between the rotating frame 22 and the mounting frame 13. At this time, the steel bar only needs to be placed horizontally in the U-shaped groove formed by the second limiting plate 142 and the first limiting plate 131. The end of the steel bar contacts the surface of the baffle 151, and the control switches of the third motor 21 and the electric push rod 23 are operated. The third motor 21 drives the rotating frame 22 to rotate until it is horizontal, and the end of the clamping rod 241 contacts the top of the mounting frame 13. The electric push rod 23 drives the moving rod 24 to move through the connecting frame, and the clamping rod 241 and the clamping block 242 move toward the steel bar to complete the clamping of the steel bar. At this time, the electric push rod 23 completes the movement of the first section, and then operates the control switches of the second motor 14 and the first motor 12. The electric push rod 23 completes the second segment of movement, and the second motor 14 drives the reciprocating screw 141 to rotate. The reciprocating screw 141 drives the moving seat 143 and the second limit plate 142 to move toward the cutting blade 121 during rotation, and the moving arm of the electric push rod 23 moves synchronously, so that the second limit plate 142 and the clamping rod 241 and the clamping block 242 always keep the steel bar clamped. The first motor 12 drives the cutting blade 121 to rotate at a high speed. When the steel bar contacts the cutting blade 121, the cutting process is completed. , the second motor 14 stops working, and the third motor 21 drives the rotating frame 22 to rotate. When the rotating frame 22 rotates, the second motor 14 drives the reciprocating screw rod 141 to move in the opposite direction, so that the second limit plate 142 is reset, and the electric push rod 23 pushes the moving rod 24 to move out of the inside of the rotating frame 22 and reset. At this time, the two sections of the steel bar are respectively unlocked and fall downward, so that the automatic falling of the steel bar can be realized. After installing the above steps, the workers only need to load the steel bars and then stay away from the device, which can avoid the influence of sparks and smoke on the workers.

[0030] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
