[0039] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0040] A tooling for cutting and beveling short-flange thick plate parts, such as Figure 1 As shown, the system includes a cutting worktable 1, with a folding plate holder 2 on one side. Since the workpiece to be folded is not easily laid flat on the horizontal surface of the cutting worktable 1, it is placed on one side of the worktable 1 and positioned by the folding plate holder 2, facilitating subsequent beveling. The folding plate holder 2 is used to fix the workpiece to be cut. A cutting device 3 is provided on the cutting worktable 1. After the workpiece is fixed, the cutting device 3 performs beveling on the required cutting position on the processing side 8 of the workpiece. During processing, the cutting device 3 is controlled by a traveling mechanism 4 to move along the processing direction of the workpiece.

[0041] As one embodiment of the folded edge plate jig 2:

[0042] Specifically, such as Figure 1As shown, the flanged plate jig 2 comprises a support frame 5, a plane support frame 6, and a slope support frame 7. The support frame 5 is vertically arranged on the ground. In actual use, a lifting device can be arranged on the support frame 5 to form a flanged plate jig 2 structure that can be adjusted in height. The support frame 5 is provided with the plane support frame 6 and the slope support frame 7. The opening angle between the plane support frame 6 and the slope support frame 7 is matched with the flanging angle of the workpiece. During processing, the flanging line of the flanged plate workpiece is aligned with the intersection of the plane support frame 6 and the slope support frame 7, so that the two sides of the flanged plate are in contact with the surfaces of the plane support frame 6 and the slope support frame 7, thereby increasing the contact area and the stability of the fixation. In the embodiment, the angle between the plane support frame 6 and the slope support frame 7 is a fixed angle. Therefore, the angle between the two is determined during the manufacture of the tooling, so as to be matched with the flanged workpiece after processing. In order to improve the fixation effect, the workpiece needs to be electrically welded with the flanged plate jig 2 after being placed on the flanged plate jig 2. In actual processing, as shown in Figure 1 、 2 , the workpiece side away from the cutting table 1 is the processing side 8. The processing side 8 extends out of the plane support frame 6. The hatched part in the figure is the excess amount added to the flanged plate. In actual processing, the excess amount needs to be cut off first, and then the processing side 8 is subjected to beveling operation in the second processing.

[0043] As shown in Figure 1 , the cutting device 3 comprises a walking base 9. The walking base 9 is provided with a cantilever frame 10 at the upper portion. The cantilever frame 10 is used to extend the cutting head 12 to the processing position. The cantilever frame 10 is provided with a vertical frame 11 that can adjust the horizontal position. The vertical frame 11 can vertically approach the processing position. The vertical frame 11 is provided with a cutting head 12 that can adjust the cutting angle. In actual use, the cutting head 12 is an acetylene gas cutting head or a plasma cutting gun head. As shown in Figure 1 、 2 , the vertical frame 11 can move horizontally on the cantilever frame 10 and be quickly fixed. In the vertical frame 11, a sleeve is arranged in a direction perpendicular to the vertical frame 11. The sleeve is slidably connected to the cantilever frame 10. A locking bolt screwed on the sleeve can fix the position. Similarly, a sleeve that can adjust the angle is arranged at the lower end of the vertical frame 11, so as to facilitate the adjustment and fixation of the angle of the cutting gun head. As shown in Figure 1 , the gun head marked as 1 is the position of the first cutting. At this time, the processing line of the cutting head 12 is in the vertical direction, so as to cut off the excess amount. Then, the position of the vertical frame 11 is moved, and the angle of the cutting head 12 is adjusted, so that the processing line direction of the cutting head 12 is the same as the angle of beveling, that is, Figure 1The position indicated by the gun head marked 2 is the location of the second cut. After cutting on both sides, a thick plate part with a short folded edge can be obtained.

[0044] As another embodiment of the folded edge plate frame 2:

[0045] In the aforementioned embodiment, the angle between the planar support 6 and the sloping support 7 in the folding plate jig 2 is fixed. Since the workpiece being folded can be processed at various angles, a fixed angle would make it difficult to securely place and fix the workpiece. As an improvement, specifically, such as... Figure 3 As shown, in this embodiment, the planar support 6 and the slope support 7 are controlled by an angle adjustment mechanism 13, allowing their angles to be flexibly adjusted according to the angle of the workpiece. Multiple planar supports 6 arranged in a comb-like pattern are evenly spaced on the upper part of the support frame 5 of the folding plate jig 2, with the upper edges of the multiple planar supports 6 forming a horizontal surface supporting the folding plate. Multiple slope supports 7 are arranged in a comb-like pattern, and the slope supports 7 and planar supports 6 are staggered. The opening angle formed between the slope supports 7 and planar supports 6 is controlled by the angle adjustment mechanism 13. A rotating shaft 14 is provided at the staggered position of the slope supports 7 and planar supports 6. The slope supports 7 can be rotated by the rotating shaft 14, and the lower end of the slope supports 7 is rotatably connected to the rotating shaft 14. Figure 5 , 6 As shown, the angle adjustment mechanism 13 includes a base plate 15, a cross shaft 16, an adjusting screw 17, and a support beam 18. The horizontal axis 19 of the cross shaft 16 is rotatably connected to the base plate 15, and the vertical axis 20 of the cross shaft 16 is provided with a screw hole 21. The adjusting screw 17 is screwed through the screw hole 21. The support beam 18 is fixedly provided on the back of the slope support 7. The upper end of the adjusting screw 17 is connected to the support beam 18 through a connecting component, and the lower end of the adjusting screw 17 is provided with an adjusting handle 23. In actual use, the position of the base plate 15 is fixed. The rotation of the adjusting screw 17 is controlled by the adjusting handle 23, thereby controlling the lifting or lowering of the support beam 18 and controlling the lifting angle of the slope support 7. Specifically, as shown... Figure 6 As shown, the connecting component includes a hinge 24 and a rotary joint 25. One end of the hinge 24 is fixedly connected to the support beam 18, and the other end is provided with a rotary joint 25. The rotary joint 25 is rotatably connected to the adjusting screw 17.

[0046] The traveling mechanism 4 includes a track 26, a chain 27, a sprocket 28, and a reduction motor 29. In actual use, after positioning the cutting head 12, the cutting device 3 can be controlled to move, thereby performing slant cutting operations on the workpiece.

[0047] Further, the cutting device 3 further comprises a profile following support part 30, which is arranged on the cantilever frame 10, as shown in the figure. Figure 7 As shown, the profile following support part 30 comprises a support arm 31 and a close wheel 32, the upper end of the support arm 31 is used to support the height of the cantilever frame 10, because the cantilever frame 10 extends transversely for a long length, so that the stability is reduced, therefore, in actual use, in order to improve the stability of the cutting head 12 in the moving process, it is necessary to improve the stability of the cantilever frame 10, so as to avoid the cutting line shaking caused by the up and down swinging amplitude in the moving process, specifically, the cantilever frame 10 is supported in the height direction at the end by the support arm 31, and the close wheel 32 is arranged at the bottom, the lower end of the support arm 31 is rotatably connected with the close wheel 32, so that the close wheel 32 is rollingly connected to the surface of the workpiece; so as to realize the support in the moving process with the movement of the walking base 9, and the included angle between the support arm 31 and the cantilever frame 10 is adjustable, so as to flexibly adjust the support position.

[0048] In the foregoing embodiment, the workpiece needs to be welded and fixed, which results in poor surface form of the workpiece and requires subsequent polishing operation, thereby increasing the processing procedure, the upper end of the slope support frame 7 is provided with a fixed chuck 33, the fixed chuck 33 is provided with a U-shaped clamping opening 34, the U-shaped clamping opening 34 comprises a first clamping wall 35 and a second clamping wall 36, the first clamping wall 35 is flush with the slope of the slope support frame 7, and the second clamping wall 36 is screwed with a clamping bolt 37.
