[0016] 2. In the present invention, the first transmission roller is driven to rotate by the second servo motor, and then the second synchronous wheel at one end of the first transmission roller is driven to rotate. The second transmission roller can be driven to rotate synchronously through the transmission synchronous belt and the first synchronous wheel, and then the roughening belts on the outer sides of the first transmission roller and the second transmission roller are rotated. When the electric telescopic rod drives the support plate to descend, the roughening belt on the lower side of the support plate can be dropped from the U-shaped opening of the U-shaped steel belt to its inner side, so that the inner side wall of the U-shaped steel belt is roughened, which is convenient for subsequently increasing the contact area of ​​the welding powder, thereby improving the bonding effect between the welding powder and the inner side wall of the U-shaped steel belt, and then improving the extrusion effect of the welding powder.

[0017] 3. In the present invention, the curling plate is driven to rotate by the curling hydraulic cylinder, so that the U-shaped opening of the U-shaped steel strip can be curled inward, which is convenient for the subsequent extrusion of the first layer of welding powder.

At this time, the cross plate 702 seals the U-shaped opening on the upper side of the U-shaped steel belt 19 to prevent waste chips from splashing during the roughening process, and roughens the inner side wall of the U-shaped steel belt 19, so as to facilitate the subsequent increase in the contact area of ​​the welding powder, thereby improving the bonding effect between the welding powder and the inner side wall of the U-shaped steel belt 19, and thereby improving the extrusion effect of the welding powder.

When in use, the vacuum cleaner 801 sucks air, so that the waste chips generated by the roughening of the inner wall of the U-shaped steel belt 19 can be sucked into the interior of the dust suction head 804, and then enter the interior of the two U-shaped dust suction pipes 803, and finally enter the interior of the vacuum cleaner 801 through the dust suction hose 802 at the upper end of the U-shaped dust suction pipe 803, so that the waste chips can be recycled.

[0028] like Figure 3 , Figure 4 , Figure 8 , Fig. 9 , Fig.14 As shown, both sides of the strip guide rail 2 are provided with a curling mechanism 17 located between the roughening mechanism 7 and the first powder discharging mechanism 9, and the curling mechanism 17 includes a curling plate 1703 rotatably arranged on the inner edge of the strip guide rail 2, the curling plate 1703 adopts a 1 / 4 arc segment, and the radius of the curling plate 1703 is smaller than the arc radius of the bottom of the U-shaped steel belt 19, and a fixed plate 1701 is fixedly arranged on the outer edge of the strip guide rail 2, and a curling hydraulic cylinder 1702 rotatably connected to one side of the curling plate 1703 is rotatably arranged on one side of the fixed plate 1701. Figure 8 It is a schematic diagram of the whole after the U-shaped steel belt 19 is curled. Fig. 9 1903 is a schematic diagram of the first welding powder layer 1904 on the inner wall of the U-shaped steel strip 19 after being pressed and fitted. After the first welding powder layer 1904 is pressed and fitted, the first welding powder layer 1904 can fill the area of ​​the fan-shaped steel strip 1903. After the U-shaped steel strip 19 is rolled, the U-shaped steel strip 19 includes a semi-annular steel strip 1901 at the bottom and straight steel strips 1902 integrally formed with both ends of the semi-annular steel strip 1901. The upper ends of the two straight steel strips 1902 are rolled inwardly to be provided with fan-shaped steel strips 1903. The fan-shaped steel strips 1903 are 1 / 4 arc segment, when in use, the curling plate 1703 is driven to rotate by the curling hydraulic cylinder 1702, so that the U-shaped opening of the U-shaped steel strip 19 can be curled inward, which is convenient for the subsequent extrusion of the first layer of welding powder, so that the inner wall of the U-shaped steel strip 19 is first formed with a first layer of welding powder layer 1904. On the one hand, it can prevent the first layer of welding powder from overflowing from the U-shaped opening of the U-shaped steel strip 19 during the extrusion process to avoid waste. On the other hand, it can make the welding powder squeezed into the U-shaped opening have a downward extrusion force, thereby improving the extrusion effect of the welding powder.

[0029] It should be noted that, when using this flux-cored welding wire forming processing device, firstly, the U-shaped steel belt 19 is passed through the U-shaped groove 3 and placed on the inner side of the U-shaped groove 3, and the first transmission roller 704 is driven to rotate by the second servo motor 710, and then the second synchronous wheel 707 at one end of the first transmission roller 704 is driven to rotate, and the transmission synchronous belt 708 is driven to rotate, thereby driving the first synchronous wheel 706 at the other end of the transmission synchronous belt 708, which can drive the second transmission roller 705 to rotate synchronously, and then the roughening belt 709 on the outer side of the first transmission roller 704 and the second transmission roller 705 is rotated. When the electric telescopic rod 701 drives the cross plate 702 to descend, it can drive the support plate 703 on the lower side of the cross plate 702 to descend, so that the support plate 703 can be driven to rotate synchronously. 03 The roughening belt 709 on the lower side descends from the U-shaped opening of the U-shaped steel belt 19 to its inner side, so that the inner side of the U-shaped steel belt 19 is roughened, and then the curling plate 1703 is driven to rotate by the curling hydraulic cylinder 1702, so that the U-shaped opening of the U-shaped steel belt 19 can be curled inward, and then the first servo motor 406 drives a transmission rod 403 at one end of the strip guide rail 2 to rotate, which can drive the transmission synchronous wheel 404 on the transmission rod 403 to rotate, and drive the conveying synchronous belt 405 outside the transmission synchronous wheel 404 to rotate, and then drive multiple transmission synchronous wheels 404 inside the conveying synchronous belt 405 to rotate synchronously, and then drive the transmission rod 403 in the center of multiple transmission synchronous wheels 404 to rotate, and drive multiple transmission rods 403 down By rotating the conveying wheel 402 at the end, the U-shaped steel belt 19 can be conveyed on the inner side of the U-shaped groove 3, so that the U-shaped steel belt 19 at the curling edge moves to the lower side of the lower powder tube 902, and then the second solenoid valve 904 is opened to make the welding powder inside the lower powder tube 902 fall to the inner side of the U-shaped steel belt 19 inside the U-shaped groove 3, and then the first hydraulic cylinder 10 drives the ring pressing block 1501 to descend, so that the ring pressing block 1501 extrude the welding powder inside the U-shaped steel belt 19 for the first layer, so that the welding powder is evenly squeezed onto the inner wall of the U-shaped steel belt 19, and in the process of the ring pressing block 1501 descending, since the initial pressing block 1503 at the lower end of the ring pressing block 1501 contacts the welding powder first, the welding powder at the bottom of the U-shaped steel belt 19 is squeezed first, and When the ring pressure block 1501 descends and drives the initial pressure block 1503 to be squeezed, the initial pressure block 1503 will slide into the inner side of the slide groove 1502, thereby driving the slide bar 1504 and the slide plate 1505 to rise, driving the return spring 1506 on the upper side of the slide plate 1505 to be compressed, so that the squeezing force of the initial pressure block 1503 is slowly increased, thereby improving the squeezing effect of the welding powder at the bottom of the U-shaped steel belt 19, and in the process of the ring pressure block 1501 descending, the welding powder is evenly squeezed and coated on both sides of the inner wall of the U-shaped steel belt 19, completing the extrusion of the first layer of welding powder, and then through the lower powder tube 902, the welding powder inside the lower powder tube 902 continues to be discharged to the center of the first layer of welding powder, at this time, a transmission rod 403 at one end of the strip guide rail 2 is driven to rotate by the first servo motor 406,It can drive the transmission synchronous wheel 404 on the transmission rod 403 to rotate, drive the conveying synchronous belt 405 on the outside of the transmission synchronous wheel 404 to rotate, and then drive multiple transmission synchronous wheels 404 on the inside of the conveying synchronous belt 405 to rotate synchronously, and then drive the transmission rods 403 in the center of multiple transmission synchronous wheels 404 to rotate, and drive the conveying wheels 402 at the lower ends of multiple transmission rods 403 to rotate, so that the U-shaped steel belt 19 can be transported on the inner side of the U-shaped groove 3, so that the second layer of welding powder to be extruded moves together with the U-shaped steel belt 19 to the bottom of the powder pressing block 16, and then the second hydraulic cylinder 12 drives the powder pressing block 16 to descend, so that the second layer of welding powder can be squeezed in the center of the first layer of welding powder. After the extrusion of the second layer of welding powder is completed, the second hydraulic cylinder 12 drives the powder pressing block 16 to rise. At this time, the first servo motor 406 continues to drive the conveying wheel 402 to rotate, which can drive The U-shaped steel belt 19 is transported on the inner side of the U-shaped groove 3, so that the U-shaped steel belt 19 moves to the bottom of the closing block 13 after the second layer of welding powder is extruded. At this time, since the second hydraulic cylinder 12 drives the powder block 16 to rise, it can also drive the first rack 1803 on one side of the powder block 16 to rise. The rise of the first rack 1803 drives the central gear 1801 to rotate at the lower end of the fixed bracket 1802. The rotation of the central gear 1801 drives the second rack 1804 to descend, which can drive the closing block 13 on the side of the second rack 1804 to descend, and the upper opening part of the U-shaped steel belt 19 can be squeezed through the arc surface on the lower side of the closing block 13, so that the opening part is squeezed and closed. This can be carried out in sequence, so that the entire U-shaped steel belt 19 can automatically complete the feeding and extrusion of two layers of welding powder, and the U-shaped steel belt 19 can be automatically closed to form a cylindrical welding wire.
