The push plate 18 is slidably connected in a placement groove 13. A servo motor 16 drives a threaded rod 15 to rotate. The threaded rod 15 drives the movable column 17 to move. The movable column 17 drives the push plate 18 to slide in the placement groove 13. The push plate 18 pushes the steel bar to move towards the lower feed port 2, so that one end of the steel bar can be moved to the cutting position. An electric push rod 5 is fixedly connected to the upper surface of one of the gantry frames 4. A movable plate 6 is fixedly connected to the piston end of the electric push rod 5. A pressing structure 7 is provided on the movable plate 6. A fixed column 8 is fixedly connected to the bottom of the movable plate 6. A quick-release structure 11 is provided on the fixed column 8. A snap-fit ​​groove is opened at the bottom of the fixed column 8. A snap-fit ​​block 9 is slidably connected inside the snap-fit ​​groove. A snap-fit ​​hole is opened on one side of the snap-fit ​​block 9. A cutting machine 10 is fixedly connected to the bottom of the snap-fit ​​block 9.

[0036] To achieve the pressing purpose, the pressing structure 7 includes an outer sleeve column 701 fixedly connected to the bottom of the movable plate 6, an inner sleeve column 702 slidably connected inside the outer sleeve column 701, a first spring 704 fixedly connected to the top inner part of the outer sleeve column 701, the other end of the first spring 704 fixedly connected to one side of the inner sleeve column 702, and a pressing block 703 fixedly connected to the bottom of the inner sleeve column 702.

[0038] Working principle: The reinforcing bar is placed in the placement groove 13. The servo motor 16 drives the threaded rod 15 to rotate, which in turn drives the moving column 17 to move. The moving column 17 drives the push plate 18 to slide within the placement groove 13. The push plate 18 pushes the reinforcing bar towards the downward feed opening 2. When one end of the reinforcing bar reaches the cutting position, the electric push rod 5 drives the moving plate 6 to move downward. The moving plate 6 drives the outer sleeve column 701 to move, which in turn drives the inner sleeve column 702 to move downward. The inner sleeve column 702 drives the pressing block 703 to move, thus pressing... Block 703 presses down on the reinforcing bar and compresses the first spring 704. The elasticity of the first spring 704 holds and fixes the reinforcing bar, reducing the probability of the reinforcing bar lifting due to downward pressure and reducing the risk of damage to the cutting equipment due to uneven cutting. The shift fork 114 is moved, which drives the sliding rod 112 to move. The sliding rod 112 drives the locking post 113 to move, causing the locking post 113 to disengage from the locking hole and compress the second spring 115. Then the locking block 9 is removed, making it convenient for staff to maintain and repair the cutting machine 10 on the locking block 9.
