However, for the flange with large diameter, it is difficult to process by forging, so the coiling process is generally used. The coiled flange is processed by the process of cutting the plate into strips, coiling into a round welding interface, and then flattening. The welding seam at the interface of the coiled flange needs to be processed flat by milling. In addition to the processing of the welding seam, subsequent operations such as rust removal, polishing and drilling are also needed on the surface of the flange. Currently, the processing of the welding seam is generally operated manually. However, in order to improve the processing efficiency, automatic milling equipment suitable for coiled flange vertical plate processing has also appeared.

[0068] When the flange moves to the processing position, start the two third motors 75 and the two second cylinders 73, the third motor 75 drives the cutter 76 to rotate when operating, at the same time, the second cylinder 73 extends to drive the rotating cutter 76 to move down to the same level as the top surface of the flange and the ground, then start the first cylinder 604, the first cylinder 604 extends when operating, which can push the movable frame 605 to slide along the second slide rail 602, the movable frame 605 slides, driving the U-shaped seat 601 to move, and driving the two milling assemblies 7 on the U-shaped seat 601 to move, so that the rotating cutter 76 moves along the surface of the flange welding point, at the same time, the top and bottom surfaces of the welding point are ground flat;

[0069] When the grinding of the top surface and the bottom surface of the flange welding point is completed, the third cylinder 614 is started, the third cylinder 614 is elongated to push the second rack 615 to slide, the second rack 615 moves to push the second gear 613 to rotate, the rotation of the second gear 613 drives the rotation of the rotating shaft 608 and the driving rod 609, the rotation of the driving rod 609 pushes the two short pins 611 to move through the strip-shaped holes 610 at both ends, and the moving directions of the two short pins 611 are opposite, the movement of the two short pins 611 drives the movement of the transmission sliding block 71 through the push rod 612, so that the two milling assemblies 7 move in different directions, and finally the positions of the two cutters 76 are staggered, at this time the two cutters 76 correspond to the inner side edge and the outer side edge of the flange welding point respectively, at this time the third motor 75 and the second cylinder 73 are started, the inner side edge and the outer side edge of the flange welding point can be ground, at the same time the second motor 51 on the sliding seat 41 is also started, the rotation of the second motor 51 drives the rotation of the rotating disc 52, the rotation of the rotating disc 52 drives the reciprocating movement of the connecting rod 53, and then pushes the first rack 54 to reciprocate, the reciprocating movement of the first rack 54 drives the reciprocating rotation of the first gear 32, and the reciprocating rotation of the first gear 32 drives the reciprocating rotation of the entire flange clamp 3 and the flange, when the flange rotates, the rotating cutter 76 grinds the inner and outer side edges of the flange within a certain angle range;

[0070] By arranging the flange clamp 3, the flange conveying assembly 4, the flange driving assembly 5, the adjusting assembly 6 and the two milling assemblies 7, the adjusting assembly 6 can be used to make the two milling assemblies 7 move to the top and the bottom of the flange welding point respectively, and then move to the inner side and the outer side of the flange welding point, which is beneficial to one-time grinding of the four sides without dead angle, and improves the processing quality and the processing efficiency compared with the existing equipment, and the flange driving assembly 5 can control the reciprocating rotation of the flange when the inner and outer edges of the flange are processed, which improves the processing effect of the inner and outer edges of the flange welding point.
