DETAILED DESCRIPTION

[0018] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] See also Figures 1 to 3The embodiment of the present application provides a fully automatic round steel cutting machine, including a frame 1 and multiple groups of symmetrically arranged clamping frames 7. A liftable cutter 2 is installed on the frame 1. A card slot 3 is provided on the frame 1. An abutment block 4 is slidably engaged in the card slot 3. A linear actuator 5 is installed on the frame 1. The linear actuator 5 can be a multi-stage electric cylinder. A force sensor 6 is installed at the output end of the linear actuator 5. The force sensor 6 can be a pressure sensor. The force sensor 6 is arranged in conjunction with the linear actuator 5. Two air brakes are rotatably installed on the clamping frame 7. The two hollow turntables 8 are symmetrically arranged vertically. A drive mechanism for rotating the hollow turntables 8 is mounted on the clamping frame 7. A pressure cylinder 9, which can be either a pneumatic or hydraulic cylinder, is mounted on the hollow turntable 8. The input end of the pressure cylinder 9 is connected to the hollow turntable 8. The output end of the pressure cylinder 9 is mounted on an extrusion wheel 10, which has a curved extrusion surface. The input end of the hollow turntable 8 is connected to a pressure source input pipe 12 via a rotary joint 11. The corresponding pressure source input pipe 12 should be connected to a pneumatic or hydraulic pump. The drive mechanism, linear actuator 5, and the drive device driving the cutter 2 are all connected via processor electrical signals.

[0020] In this embodiment, the round steel is placed between the extrusion wheels 10 on the clamping frame 7. The two extrusion wheels 10 on the symmetrically arranged multiple groups of clamping frames 7 can transport the round steel. The pressure source is input through the pressure source input pipe 12 and transmitted to the pressure cylinder 9 through the hollow turntable 8, so that the extrusion wheel 10 can be pushed out, so that the extrusion wheel 10 with an arc-shaped extrusion surface can extrude round steels of different specifications. When the round steel is transported and cut by the extrusion wheel 10, the extrusion and fixing effect is better, so that the cutting effect is better; the rotary joint 11 enables the hollow turntable 8 to transport the pressure source and rotate; after the round steel is transported through the cutter 2, it squeezes the abutment block 4, causing it to slide in the slot 3. When the abutment block 4 is pushed to a specified distance by the round steel, pressure is applied to the force sensor 6 on the linear actuator 5, and the driving mechanism stops transporting the round steel. At this time, the cutter 2 can be controlled to cut the round steel. After a single cut is completed, the linear actuator 5 can be controlled to push the abutment block 4 back to its initial position. After the abutment block 4 abuts against the force sensor 6, the linear actuator 5 will not be retracted. The linear actuator 5 can drive the force sensor 6 to be located at different positions, so that the cutting machine can cut round steel of different lengths.

[0021] In some embodiments, to facilitate driving the extrusion wheel 10 to convey the round steel, a drive mechanism is provided including a rotary drive device 13. The rotary drive device 13 can be a servo motor. A gear 14 is mounted on the hollow turntable 8. Two gears 14 on the same clamping frame 7 are meshed and connected. The output end of the rotary drive device 13 is connected to one of the gears 14 via a belt drive assembly. The meshing of the two gears 14 allows the rotary drive device 13 to rotate the two hollow turntables 8 in opposite directions via the belt drive assembly, thereby driving the extrusion wheel 10 to convey the round steel.

[0022] In some embodiments, in order to facilitate the blanking of the cut round steel, a through slot 15 is provided on the frame 1, and the through slot 15 is located below the cutter 2 and the clamping slot 3. Thus, the cut portion of the round steel can fall directly from the wider through slot 15.

[0023] In some embodiments, in order to facilitate the cut portion of the round steel to fall from the through slot 15 , chamfers are provided on both sides of the through slot 15 .

[0024] In some embodiments, in order to facilitate driving the cutter 2 to move up and down, a second linear actuator 16 is installed on the frame 1, and the cutter 2 is installed at the output end of the second linear actuator 16.

[0025] In some embodiments, in order to facilitate the protection of the pressure cylinder 9 , a plurality of telescopic support rods 17 are installed on the hollow turntable 8 , and the output ends of the telescopic support rods 17 are connected to the extrusion wheel 10 .
