[0049] like Figure 1-20 As shown, a flux-cored welding wire machine that integrates forming, drawing, and rubbing is shown, comprising a pay-off machine 1, a tensioner 2, a forming machine 3, an electrical control cabinet 4, a wire drawing machine 5, a wire rubbing machine 6, and a wire take-up machine 7, which are installed in sequence. The forming machine 3 includes several groups of roller structures, each group of which includes vertical roller structures 3-4 and flat roller structures 3-5. The pass profiles of each group of vertical roller structures 3-4 and flat roller structures 3-5 are different, and the pass profiles of the vertical roller structures 3-4 gradually decrease from the direction of steel strip entry to the direction of steel strip exit. The wire drawing machine 5 includes several groups of wire drawing assemblies, each group of which has a different speed, and the speed of each group of wire drawing assemblies gradually increases from the direction of steel strip entry to the direction of steel strip exit. The rollers of the vertical roller structure 3-4 are made of tungsten carbide, ensuring a long service life. The vertical rollers are driven by servo motors, while the flat roller structure 3-5 is unpowered. The upper rollers of the vertical roller structure 3-4 are adjustable both vertically and horizontally. The front and rear flat roller structures 3-5 are both movable and independently adjustable vertically, ensuring smooth transport of the steel strip. An electrical control cabinet 4 is located between the forming machine 3 and the wire drawing machine 5.

[0050] like Figure 2 As shown, the pay-off machine 1 and the take-up machine 7 have identical structures, both including a protective frame 1-1, on which a spool 1-2 is rotatably mounted. A telescopic sleeve 1-3 is detachably mounted on one end of the spool 1-2, and the other end is connected to a synchronous pulley via a main shaft 1-8. The synchronous pulley is connected to a pulley 1-6 via a belt 1-7, which is keyed to the rotating shaft of a motor 1-5. Telescopic cylinders 1-4 are symmetrically mounted on the telescopic ends of the telescopic sleeve 1-3, and pneumatic brakes 1-9 are symmetrically mounted on the main shaft 1-8. During operation, spool 1-2 loaded with steel strip is pushed into the center of the equipment. Two tips are located on either side of spool 1-2. A button is operated, and telescopic cylinder 1-4 pushes telescopic sleeve 1-3 with its tips into spool 1-2. Motor 1-5 drives spool 1-2 through pulley 1-6 and belt 1-6, rotating it, allowing the steel strip on spool 1-2 to be unwound or rewound. During operation, the unwinding and rewinding speeds are controlled by a frequency converter to match the overall equipment speed.

[0051] like Figure 3-4 As shown, the tensioner 2 includes a box body 2-3, and a fixed guide wheel 2-2 and a movable guide wheel 2-1 are symmetrically installed on the upper and lower parts of the box body 2-3. The movable guide wheel 2-1 is installed on the movable guide wheel slider 2-4, and a cylinder 2-7 is installed at the center position of the upper end of the movable guide wheel slider 2-4. A slidable guide light shaft 2-5 is symmetrically installed on the upper end surface of the movable guide wheel slider 2-4, and the guide light shaft 2-5 is installed in the box body 2-3. An inclined iron 2-9 is installed on one side wall of the movable guide wheel slider 2-4, and a proximity analog sensor 2-8 is installed on the other side of the inclined iron 2-9. The proximity analog sensor 2-8 is used to detect the distance between the inclined iron 2-9 and the proximity analog sensor 2-8. A pressure regulating valve 2-6 is installed on the outer side wall of the box body 2-3. The steel belt passes through fixed guide wheel 2-2 and movable guide wheel 2-1 before entering forming machine 3. Fixed guide wheel 2-2 is fixed, while movable guide wheel 2-1 moves up and down via cylinder 2-7, driving movable guide wheel slider 2-4. When the steel belt becomes too tight, movable guide wheel 2-1 is pulled to a higher position. Proximity analog sensor 2-8 detects the change in distance via inclined iron 2-9, transmits the data to the machine's PLC, and then adjusts the speed of the equipment.

[0052] like Figure 5 As shown, the forming machine 3 includes a speed measuring mechanism 3-1, a steel strip oiler 3-2, and several groups of roller structures, which are installed in sequence. A powder feeder 3-7 and an empty powder detection laser sensor 3-8 are installed in the middle of the several groups of roller structures. Figure 20As shown, the empty powder detection laser sensor 3-8 detects the powder height within the U-shaped groove of the steel strip, monitors the filling level, and directly issues an alarm to shut down the machine when the filling level is seriously insufficient. A production signboard 3-3 is installed at the top of the forming machine 3 to display production information during production line operation, such as the operator number, brand and batch number of the welding wire being produced, current output, current production speed, etc. Roller height display screens 3-6 are installed at the top of several groups of the roller structures to display the current upper and lower positions of the rollers. The speed measuring mechanism 3-1 presses the speed measuring wheel against the steel strip, detects the forward speed of the steel strip via an encoder, and transmits the signal to the electrical control cabinet 4 to ensure that the powder addition amount changes with the speed of the steel strip.

[0053] like Figure 6-7 As shown, the steel strip oiler 3-2 includes a workbench 3-2-12, which is vertically mounted on a base. On the right side of the workbench 3-2-12, guide wheels 3-2-1 with an S-shaped distribution are installed. The steel strip passes over the guide wheels 3-2-1 from bottom to top, forming an S-shaped curve.

[0054] A pressure roller 1 3-2-3 is mounted on the left side of the S-shaped guide roller 3-2-1, and a pressure roller 2 3-2-4 is mounted on the left side of the pressure roller 1 3-2-3. Pressure rollers 1 3-2-3 and 3-2-4 are located on the same horizontal line. An oiling roller 3-2-5 is mounted below the central axis of the pressure rollers 1 3-2-3 and 3-2-4. The steel strip is lubricated from below the pressure roller 1 3-2-3 to above the oiling roller 3-2-5, and then below the pressure roller 2 3-2-4, completing the lubrication process on the side of the steel strip that contacts the oiling roller 3-2-5. The right side of the oiling roller 3-2-5 is in frictional contact with an oil guide roller 3-2-6. An oil receiving box 3-2-7 is mounted below the oiling roller 3-2-5 and the oil guide roller 3-2-6. The oiling roller 3-2-5 is made of a resin material with good oil adhesion. An oil dripping pipe 3-2-2 is installed above the oil guide wheel 3-2-6. The oil dripping pipe 3-2-2 passes through the workbench 3-2-12 and is connected to the oil pipe 3-2-11. The oil pipe 3-2-11 is connected to an oil supply mechanism. The oil supply mechanism includes a peristaltic pump 3-2-10 connected to the oil pipe 3-2-11. The peristaltic pump 3-2-10 is connected to the oil storage tank 3-2-9 through a pipeline. The oil storage tank 3-2-9 has an oil level detection sensor 3-2-8 installed in it.

[0055] The steel belt passes through the guide wheel 3-2-1, the pressure wheel 1 3-2-3, the oiling wheel 3-2-5 and the pressure wheel 2 3-2-4 in sequence.

[0056] The guide wheel 3-2-1, pressure wheel 1 3-2-3, oiling wheel 3-2-5, pressure wheel 2 3-2-4 and oil guide wheel 3-2-6 are all driven wheels. The steel strip moves forward driven by the forming machine rollers, and the oil guide wheel 3-2-6 moves by the friction between it and the oiling wheel 3-2-5.

[0057] The operation of lubricator 3-2 is as follows: Driven by the forming machine rollers, the steel strip passes through the guide roller, the bottom of the first pressure roller, and then passes over the top of the oiling roller, which drives the oil guide roller to rotate. The oil dripping from the oil dripping tube onto the oil guide roller is transferred to the oiling roller, accurately and evenly coating one side of the steel strip before exiting from the bottom of the second pressure roller. During this process, a peristaltic pump precisely controls the oil flow, an oil level sensor monitors the oil level in the storage tank, and an oil collection box recycles the oil to avoid waste.

[0058] like Figure 8-10 As shown, it includes a base 3-7-1, with brackets 3-7-3 symmetrically mounted on the upper end of the base 3-7-1. A silo 3-7-6 is mounted above the bracket 3-7-3, and an observation port 3-7-9 is mounted on the side wall of the silo 3-7-6. A level detection sensor 3-7-16 is mounted on the silo 3-7-6 for detecting the powder content in the silo 3-7-6. A mounting plate 3-7-8 is mounted on the upper end of the silo 3-7-6, which is mounted to the base 3-7-1 via silo supports 3-7-7. A gate 3-7-10 is mounted below the silo 3-7-6. The gate is adjusted using a micrometer head for higher precision. A powder transfer mechanism is installed below the gate 3-7-10.

[0059] A feeding device 3-7-17 is installed below the left end of the powder conveying mechanism. The left and right ends of the feeding device 3-7-17 are mounted on the outer wall of the bracket 3-7-3 via a feeding device bracket 3-7-18. A powder collecting box 3-7-2 is installed below the feeding device 3-7-17 to collect excess powder splashed during the feeding process. The powder conveying mechanism is installed on a sliding assembly bracket 3-7-14. A slider 3-7-13 is installed on the lower end surface of the sliding assembly bracket 3-7-14. The slider 3-7-13 is slidably mounted on a slide rail 3-7-12. The slide rail 3-7-12 is mounted on the upper end surface of the base 3-7-1. The slider 3-7-13 drives the sliding assembly bracket 3-7-14 to move on the slide rail 3-7-12, realizing the movement of the powder conveying mechanism, facilitating the maintenance of the powder conveying mechanism, and eliminating the need to disassemble precision components such as the gate during maintenance. The powder conveying mechanism is driven by a servo motor 3-7-5.

[0060] Several weighing sensors 3-7-11 are symmetrically installed on the lower end surface of the base 3-7-1. The weighing sensors 3-7-11 are electrically connected to the weighing control system, the weighing control system is electrically connected to the servo control system, and the servo control system is electrically connected to the servo motor 3-7-5, forming a closed-loop control of the weighing control system, servo controller, servo motor, and weighing sensors. That is, after the system sets the corresponding filling amount, the weighing control system sends a signal to the servo controller to drive the servo motor to operate, and the powder adding belt delivers powder. The weighing sensor detects weight changes in real time, feeds back signals to the weighing control system, and adjusts the servo motor speed in real time according to the weight changes.

[0061] The powder conveying mechanism includes a driving wheel 3-7-15 connected to the shaft end of the servo motor 3-7-5. The driving wheel 3-7-15 is mounted on the sliding assembly bracket 3-7-14. An adjustment plate 3-7-20 is installed on the side of the sliding assembly bracket 3-7-14 away from the driving wheel 3-7-15. The adjustment plate 3-7-20 is connected to the passive wheel bracket 3-7-21 via an adjustment bolt. The passive wheel bracket 3-7-21 is mounted on the passive wheel bracket 3-7-21. The driving wheel 3-7-15 and the passive wheel 3-7-19 are connected together by a powder feeding belt 3-7-4. The driving wheel 3-7-19 drives the driven wheel 3-7-15 to rotate via the powder feeding belt 3-7-4. A tensioning wheel 3-7-22 for adjusting the tension is installed between the driving wheel 3-7-15 and the passive wheel 3-7-19.

[0062] like Figure 11-12As shown, the wire drawing machine 5 includes a reel 5-2. The number of reels 5-2 varies depending on the material of the welding wire and the diameter of the finished wire. In the present invention, the number of reels is 10-14. A permanent magnet motor 5-1 is mounted at the lower end of the reel 5-2. A swing arm pulley 5-3 is mounted on the outer side of the reel. One end of the swing arm pulley 5-3 is hinged to the swing arm pulley mounting plate, and the other end is connected to a tension adjustment cylinder 5-5. A proximity sensor 5-6 for detecting the distance between the swing arm pulley 5-3 and the reel 5-2 is mounted on the swing arm pulley mounting plate. A drawing die box 5-4 is mounted to the right side of the swing arm pulley mounting plate. The wire drawing machine 5 is internally provided with a water inlet and return pipes. Cooling water is sprayed on the reel 5-2 and the drawing die inside the drawing die box 5-4 to cool the wire drawing die. After the steel strip passes around the reel 5-2 and the swing arm pulley 5-3, it passes through the drawing die box 5-4. The welding wire is wound onto the reel 5-2 of the wire drawing machine 5 and drawn. The wire enters the drawing die in the drawing die box 5-4 and is reduced in diameter by extrusion. With each reduction, the linear speed of the drawing reel 5-2 increases. At this time, the swing arm wheel 5-3 is close to the welding wire. As the speed of the reel 5-2 varies, the swing arm wheel 5-3 will change position due to different tensions. The tension adjustment cylinder 5-5 applies reverse tension to the swing arm wheel 5-3. The proximity sensor 5-6 detects the real-time position of the swing arm wheel. Based on the position of the swing arm wheel 5-3, the tension between the reels 5-2 is detected. Feedback is sent to the control system to adjust the speed of the reel 5-2.

[0063] like Figure 13-19 As shown, the cabinet includes a wire feed reel 6-1 and a wire discharge reel 6-2, symmetrically mounted on the outer wall of the cabinet. These reels stabilize the welding wire and facilitate the connection of the wire grater to the preceding and following equipment throughout the welding wire production line. The cabinet is internally mounted with a matrix of wire reels 1 6-3, 2 6-4, 3 6-5, and 4 6-6. These reels 1 6-3, 2 6-4, 3 6-5, and 4 6-6 increase the dwell time of the welding wire within the wire grater and increase the contact area between the welding wire and the scouring pad. A control box 6-9 is mounted on the outer wall of the cabinet to control the start and stop of the equipment within the cabinet.

[0064] The wire wheel 2 6-4 is located directly below the wire wheel 1 6-3, and several groups of front and rear wiping mechanisms 6-8 are installed between the wire wheel 1 6-3 and the wire wheel 2 6-4; the wire wheel 3 6-5 is located directly below the wire wheel 4 6-6, and several groups of left and right wiping mechanisms 6-7 are installed between the wire wheel 3 6-5 and the wire wheel 4 6-6. Several groups of the front and rear wiping mechanisms 6-8 and the left and right wiping mechanisms 6-7 all include a scouring pad 6-12 wrapped around the welding wire to wipe the surface of the welding wire. The specific number of the front and rear wiping mechanisms 6-8 and the left and right wiping mechanisms 6-7 is four groups, and they are symmetrically distributed in pairs. The scouring pad 6-12 is installed on the movable plate 6-16 through the splint 6-11. The movable plate 6-16 is connected to an eccentric wheel structure. The eccentric wheel structure drives the movable plate 6-16 to move forward and backward or left and right to wipe the surface of the welding wire in two directions, thereby improving the cleaning efficiency. The upper and lower ends of the splint 6-11 are respectively installed with symmetrically distributed guide sleeves 6-14, and a matching guide rod 6-15 is installed in the guide sleeve 6-14. The other end of the guide rod 6-15 is installed on the middle sandwich panel inside the cabinet. The guide rod 6-15 moves in the guide sleeve 6-14, limiting the moving direction of the movable plate 6-11.

[0065] The eccentric wheel structure includes a motor 6-20, the shaft end of the motor 6-20 is connected to a reducer 6-21, the upper and lower output shafts of the reducer 6-21 are connected to the main shaft 6-22, the top of the main shaft 6-22 is installed with an eccentric wheel 6-23, and the eccentric wheel 6-23 is installed with a pin 6-24 away from the center.

A dust exhaust pipe 6-17 is installed inside the cabinet, and the top of the dust exhaust pipe 6-17 extends out of the outside of the cabinet. The branch pipes of the dust exhaust pipe 6-17 are all equipped with a dust suction port 6-18. The dust suction port 6-18 is located on the side of the cabinet where the wire wiping mechanism is installed, and the wiped dust is discharged out of the cabinet through the dust exhaust pipe 6-17. A dust collecting box 6-10 is installed at the bottom of the cabinet to collect heavier dust for easy disposal. The above two dust treatment schemes can effectively prevent the wiped dust from contaminating the welding wire again and improve the cleaning effect.

[0067] The action process of the present invention is as follows:

[0068] First, the welding wire enters the cabinet from inlet reel 6-1, then passes through wire pulley 1 6-3, wire pulley 2 6-4, wire pulley 1 6-3, wire pulley 4 6-6, wire pulley 3 6-5, and wire pulley 4 6-6. The wire is cleaned multiple times by the wire-wiping mechanism before exiting from outlet reel 6-2. During this process, air knife 6-13 removes lubricating powder adhering to scouring pad 6-12 and dust from the machine interior. Heavier dust is collected in dust box 6-10, while lighter dust is discharged from the cabinet through dust exhaust duct 6-17.

[0069] The process of the present invention is as follows:

[0070] The first step is to push the spool loaded with steel strip onto the pay-off machine and start the pay-off machine to pay off the strip;

[0071] In the second step, the steel belt passes through the tensioner, which detects the running status of the steel belt and transmits the signal to the electric control cabinet;

[0072] In the third step, after the steel strip has been speed-measured and oiled, it enters the forming machine for cold bending, transforming the flat steel strip into a steel strip with an upward groove. Powder is then added through the powder feeder, and then cold bending is performed again, finally becoming a round steel strip, i.e. welding wire.

[0073] In the fourth step, the steel wire is wound onto the wire drawing machine drum for traction, and then enters the wire drawing die in the wire drawing die box to reduce the diameter by extrusion;

[0074] In the fifth step, the wire machine moves the outer surface of the steel wire back and forth and left and right with a scouring pad to wipe off the residual lubricating oil and other impurities on the surface of the steel wire;

[0075] The sixth step is to take up the welding wire through the wire take-up machine.

[0076] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by persons skilled in the art should fall within the scope of protection defined by the claims of the present invention.
