The upper part of the filter screen 53 is used to place the cut steel bars 4, and the inner cavity of the placing frame 5 below the filter screen 53 is used to place metal chips. The through holes on the surface of the filter screen 53 can effectively prevent the steel bars 4 from falling down, but will not prevent the passage of metal chips. A detachable baffle 52 is fixedly arranged on the outer side surface of the placing frame 5 through bolts. When the metal chips accumulate to a certain extent, loosen the bolts, open the baffle 52, and then centrally clean the metal chips.

[0021] Reference Figure 1 , on the upper surface of the machine base 1, at a position close to the side of the first through groove 11, a U-shaped bracket 2 is fixedly arranged. A control box 21 is fixedly arranged on the outer side surface of the U-shaped bracket 2. A first telescopic cylinder 22 is fixedly arranged on the lower surface of the U-shaped bracket 2. The lower end of the piston rod of the first telescopic cylinder 22 is fixedly provided with a mounting frame 24. A first motor 25 is fixedly arranged inside the mounting frame 24.

At the lower end of the piston rod of the telescopic second air cylinder 31, a support 32 is fixedly arranged. The upper feeding wheel 33 is rotatably arranged on the support 32, and the lower feeding wheel 33 is fixedly arranged on the surface of the output shaft of the second motor 35. An arc-shaped groove is formed on the surface of the feeding wheel 33. The two feeding wheels 33 cooperate to fixedly clamp the steel bar 4, and the rotation of the lower feeding wheel 33 can be driven by the second motor 35 to push the steel bar 4.

[0027] Further, after the steel bar 4 is placed in the arc-shaped groove of the lower feeding wheel 33, the telescopic second air cylinder 31 is started to lower the upper feeding wheel 33, then the steel bar 4 is clamped, then the second motor 35 is started to drive the lower feeding wheel 33 to feed and push the steel bar 4, and then the steel bar 4 is cut by the cutting blade 26.
