[0028] like Figure 1 to Figure 5 As shown, the motor 1 9 , the telescopic rod 22 and the motor 2 14 are all electrically connected to the control panel 2 .

[0029] like Figure 1 to Figure 5 As shown, a plurality of arrays of equally spaced contraction grooves are provided inside the clamping plate 5 and the pressure plate 6, and the telescopic block 24 is slidably connected inside the contraction groove. A spring 25 is provided inside the contraction groove, and the spring 25 is connected between the contraction groove and the telescopic block 24.

During clamping, the setting of each separate telescopic block 24 and spring 25 can achieve perfect fitting to the surface of steel bars with different shapes, which is more stable during subsequent cutting. After fixing, start the motor 9, which is a servo motor. When the motor 9 rotates forward, it drives the threaded rod 10 to rotate to realize the upward movement of the transmission sleeve 11. During the upward movement, the rotating rod 17 is driven to rotate by the synchronous belt 16, thereby realizing the meshing of the active bevel gear 18 and the driven bevel gear 19, so that the reciprocating screw rod 20 is opened and rotated, and the reciprocating screw When the rod 20 rotates, it will drive the cleaning plate 23 to move along the direction of the thread to clean the surface of the steel bar. The function of the telescopic rod 22 is to drive it to adjust its height through electrical control. The initial position of the transmission sleeve 11 is in the middle of the threaded rod 10. During the cleaning process, it is in an upward state. When the transmission sleeve 11 moves to the top, the cleaning is completed. At this time, the cleaning plate 23 moves to one side of the steel bar and does not affect normal cutting. At this time, the motor 19 reverses. When the motor 19 reverses, the reciprocating screw rod 20 is ensured not to rotate by the setting of the one-way shaft 29. At this time, the transmission sleeve 11 drives the protective sleeve 13 to move downward along the thread, and the motor 2 14 is started to drive the cutting blade 15 to cut the steel bar. After cutting, the motor 2 14 stops, and the motor 19 rotates forward to drive the cutting blade 15 to move the cleaning plate 23 upward to start working.

[0035] Example 2

[0036] like Figure 1 to Figure 5As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the guide assembly 28 includes two symmetrically arranged springs 27, the springs 27 are welded inside the protective cover 13, and one end of the springs 27 is welded with a limiting plate 26. Through the arrangement of structures such as the springs 27 and the limiting plate 26, when the cutting blade 15 rotates for cutting, the direct contact with the steel bar will cause the cutting blade 15 to vibrate, thereby causing unstable cutting. The arrangement of the limiting plate 26 and the springs 27 can achieve the effect of limiting and shock absorption.

[0037] In this embodiment, during the operation of the cutting blade 15, vibration will occur due to direct contact with the steel bar. The vibration will cause the cutting line to shift and the cutting effect to decrease. Therefore, the position of the cutting blade 15 can be limited by setting a limit block, and the vibration can be reduced by the reaction force of the spring 27.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
