[0021] During processing, the steel bar is pushed forward by utilizing the arc groove opened at the top of the guide plate 11, and the rotating motor 13 is utilized to drive the gear 1 131 to rotate, and the engagement with the two gear 2s 15 can drive the two rotating rods 14 and the left and right straightening wheels 16 at the top to rotate in opposite directions, thereby clamping and straightening the steel bar and conveying it forward. When it reaches below the level of the inverted U-shaped bracket 21, the hydraulic telescopic device 22 is utilized to drive the fixed plate 23 to move downward, so that the steel bar pressing wheel 25 between the two pressing wheel brackets 24 is pressed against the top of the steel bar, and the concave part in the middle of the steel bar pressing wheel 25 is utilized to extrude and straighten it, and the steel bar pressing wheel 25 is driven to rotate by the driving motor 26 to continue to push the steel bar forward.

[0022] like Figure 4As shown, the cutting mechanism 3 includes an upright bracket 31, the upright bracket 31 is located at the front side of the inverted U-shaped bracket 21, an extension plate 32 is fixedly installed on the top of the upright bracket 31, an electric push rod 1 33 is fixedly installed on the top of the extension plate 32, the output shaft of the electric push rod 1 33 passes through the bottom of the extension plate 32 and is fixedly installed with a cutter 34, a through hole 35 that passes through the front and back is opened at the bottom of the upright bracket 31, steel bar introduction plates 36 are fixedly installed on the left and right sides of the rear end of the upright bracket 31, and electric push rods 2 37 are fixedly installed on the opposite back surfaces of the two steel bar introduction plates 36, and the output ends of the two electric push rods 2 37 pass through the opposite surfaces of the two steel bar introduction plates 36 and are fixedly installed with arc edge clamps 38;

[0023] By starting the two electric push rods 37, the arc edge clamp 38 can be driven to clamp and fix the steel bars, and then the electric push rod 33 on the top of the extension plate 32 can be started to drive the cutter 34 to move downward to cut the part extending out of the through hole 35. The cut steel bars will directly slide into the loading trough 18 using the inclined plate 17 for collection.

When steel bars of different lengths are needed as the motor shaft, the threaded rod 42 in the adjustment box 41 is driven to rotate clockwise or counterclockwise through the forward or reverse knob 43, so that the moving block 44 moves back and forth on the outer wall of the threaded rod 42, and the slide groove opened on the left side of the adjustment box 41 is used to maintain stability, drive the baffle 45 to adjust forward and backward, and at the same time observe the distance measuring ruler 48 on the top of the adjustment box 41 to facilitate adjustment to the required steel bar length.

The sensor 47 senses it, thereby controlling the electric push rod 2 37 on the back side of the two steel bar introduction plates 36 to start, driving the arc edge clamp 38 to clamp and fix the steel bar, and then the electric push rod 1 33 on the top of the extension plate 32 can be started to drive the cutter 34 to move down, and cut the part extending out of the through hole 35. The cut steel bars will directly slide into the loading trough 18 for collection using the inclined plate 17. When steel bars of different lengths are needed as the motor shaft, the threaded rod 42 in the adjustment box 41 is driven to rotate clockwise or counterclockwise through the forward or reverse knob 43, so that the moving block 44 moves back and forth on the outer wall of the threaded rod 42, and the slide groove opened on the left side of the adjustment box 41 is used to maintain stability, driving the baffle 45 to adjust back and forth, and at the same time observing the distance measuring ruler 48 on the top of the adjustment box 41 to facilitate adjustment to the required steel bar length.
