[0002] Flux-cored welding wire is also called powder-cored welding wire and tubular welding wire. It is divided into two categories: gas-protected and non-gas-protected. The surface of flux-cored welding wire is the same as solid welding wire. It is made of low-carbon steel or low-alloy steel with good plasticity. Its manufacturing method is to first roll the steel strip into a U-shaped cross-section shape, and then add the welding powder prepared according to the dosage into the U-shaped steel strip, roll it tightly with a rolling mill, and finally draw it into flux-cored welding wire of different specifications. During the processing of flux-cored welding wire, it is often necessary to cut the flux-cored welding wire into the required length. In order to ensure the high efficiency of flux-cored welding wire during processing and cutting and improve the degree of intelligence, a CNC cutting machine is needed to process the produced welding wire.

[0033] In summary, when the CNC cutting machine for welding wire processing performs online equal-length cutting of the flux-cored welding wire 2 to be cut, when the flux-cored welding wire production equipment delivers the flux-cored welding wire 2 to be cut, according to the diameter of the flux-cored welding wire 2 to be cut, the limiting bolt sliding sensing column 2 47 is removed, so that the sensing column 2 47 is convenient for sensing the flux-cored welding wire 2 to be cut, and then the position of the sensing column 2 47 is stabilized by the limiting bolt and the corresponding threaded hole on the sensing column 2 47, and when the speed and length measuring sensor 48 senses the online production and conveying speed of the flux-cored welding wire production equipment for the flux-cored welding wire 2 to be cut, the information is transmitted to the motor 3 37, the motor 3 37 is started, and the motor 3 3 The output end of 7 drives the incomplete gear 38 to rotate. Due to the rotation of the incomplete gear 38, the gear plate 33 is driven to move to one side by meshing with the gear plate 33 located above, and the gear plate 33 drives the annular frame 35 to move. The incomplete gear 38 is meshed with the gear plate 33 located below to drive the gear plate 33 to move to the other side, and the gear plate 33 drives the annular frame 35 to move. Therefore, the rotation of the incomplete gear 38 drives the annular frame 35 to reciprocate. The speed of the annular frame 35 is equal to the speed of the flux-cored welding wire 2 to be cut by adjusting the speed of the motor 37, so that real-time adjustment can be performed online. The annular frame 35 is provided with The movable clamping group 2 performs reciprocating motion. According to the diameter of the flux-cored welding wire 2 to be cut, the cylinder 5 40 is started. The output end of the cylinder 5 40 drives the clamping group 2 to move to the specified position, and the cylinder 3 13 there is started to retract the output end of the cylinder 3 13. The output end of the cylinder 3 13 drives the gear plate 14 to move. The gear plate 14 drives the two gears 16 to rotate relative to each other. The relative rotation of the two gears 16 drives the two clamping claws 17 to move relative to each other. The relative movement of the two clamping claws 17 causes the anti-slip plate teeth 18 to clamp the flux-cored welding wire 2 to be cut. Similarly, the anti-slip plate teeth 18 release the flux-cored welding wire 2 to be cut by pushing out the output end of the cylinder 5 40. When the anti-slip plate teeth 18 move through the annular frame 35 to the end that is about to move away from the flux-cored welding wire production equipment, they release the flux-cored welding wire 2 to be cut. After the anti-slip plate teeth 18 move through the annular frame 35 to the end close to the flux-cored welding wire production equipment, they clamp the flux-cored welding wire 2 to be cut. Through the above principle, by adjusting the starting interval between the two motors 37, the two clamping components can seamlessly clamp and convey the flux-cored welding wire 2 to be cut through the clamping claws 17, giving the flux-cored welding wire 2 to be cut an auxiliary conveying force, which is convenient for offsetting the friction force of the moving plate 4 inside the cutting through hole, and is not easy to affect the normal production of the flux-cored welding wire production device.

[0034] When the flux-cored welding wire is cut to equal length, the length of the flux-cored welding wire to be cut is detected by the speed and length measuring sensor 48. According to the length of the flux-cored welding wire to be cut, counting starts when the head end of the flux-cored welding wire 2 to be cut moves to the bottom of the cutting knife 11. When the flux-cored welding wire 2 to be cut is detected by the speed measuring sensor to move to the set cutting length, the flux-cored welding wire 2 to be cut is clamped by the anti-slip plate teeth 18 on the clamping group 1. The flux-cored welding wire 2 to be cut drives the clamping group 1 to move, and the clamping group 1 drives the moving plate 4 to move. The moving plate 4 moves with the cutting frame 6 and the cutting device. When the head end of the flux-cored welding wire 2 to be cut passes through the limiting mechanism, according to the diameter of the flux-cored welding wire 2 to be cut, the motor 2 24 is started. The output end of the motor 24 drives the gear 25 to rotate, the gear 25 drives the two tooth plates 26 to move in phase, the tooth plate 26 drives the limit plate 27 to move, the limit plate 27 drives the baffle 28 to move, the baffle 28 drives the roller 1 29 to move, and the multiple rollers 1 29 move in phase, so that the multiple rollers 1 29 are all fitted with the flux-cored welding wire 2 to be cut, and the lateral movement of the flux-cored welding wire 2 to be cut is restricted, and then the cylinder 4 31 is started, and the output end of the cylinder 4 31 drives the baffle 32 to move, and the baffle 32 drives the roller 2 33 to move in phase, so that the roller 2 33 is fitted with the flux-cored welding wire 2 to be cut, and the longitudinal movement of the flux-cored welding wire 2 to be cut is restricted, so as to stabilize the flux-cored welding wire 2 to be cut, and then the motor 1 is started, and the output end of the motor 1 The limit rod 9 is driven to move, and the limit rod 9 drives the cutting knife 11 to rotate, and then the cylinder 15 is started, and the output end of the cylinder 15 drives the cutting frame 6 to move downward, and the cutting frame 6 drives the cutting device to move downward to cut the flux-cored welding wire 2 to be cut. When the cutting knife 11 is cutting the flux-cored welding wire 2 to be cut, the water pump 20 is started, and the water inside the water tank 19 is sprayed from the inside of the water spray head 22 through the water pipe 1, the water pump 20, and the water pipe 21 to cool the cutting knife 11, so as to increase the service life of the cutting knife 11. When replacing the cutting knife 11, it is only necessary to remove the limit block 10 with bolts to replace the cutting knife 11. After the cutting of the flux-cored welding wire 2 to be cut is completed, the anti-slip plate teeth 18 on the clamping group 1 are loosened. Open the flux-cored welding wire 2 to be cut, wherein the sliding distance of the movable plate 4 inside the cutting through hole can fully meet the cutting device to complete the cutting of the flux-cored welding wire 2 to be cut, and then start the cylinder 2 7, and the output end of the cylinder 2 7 drives the push block 8 to move, and the push block 8 pushes the movable plate 4 to move, so that the movable plate 4 is restored to the state before cutting, and the position of the movable plate 4 is stabilized by the adsorption of multiple magnets 49, and then the cutting is repeated to obtain flux-cored welding wires of equal length. When the cut flux-cored welding wire is transported, when the cut flux-cored welding wire is pushed by the flux-cored welding wire 2 to be cut and moves to the conveyor belt 43 through the limit mechanism, the motor 44 is started, and the output end of the motor 44 drives the roller 42 on one side to rotate, and the rotation of the roller 42 drives the conveyor belt 43 to move.The cut flux-cored welding wire can be moved to the designated storage position by the movement of the conveyor belt 43.
