Embodiment 1
[0060] The first solution is introduced here, reducing the width and / or thickness of the material at the fold.
[0061] It is very difficult to control the material width of the folded part simply by dislocation cutting. In fact, even if the width of the folding part is not controlled, it is difficult to perform ordinary misalignment cutting - completely cut off the upper plane and slope surface at the upper cutting part, and completely cut off the lower plane and slope surface at the lower cutting part; not to mention, The lower plane is partially cut off at the upper cutting position, and the upper plane is also partially cut off at the lower cutting position.
[0062] Therefore, our solution is to cut all the corrugated plates into corrugated strips, and weld the corrugated strips in dislocation. During the welding process, the width of the folded parts can be reduced, and the thickness and strength of the welded parts can also be reduced.
[0063] That is to say, in the c...
Embodiment 2
[0078] In the solution in Example 1, although the welding process is very simple, the subsequent folding process is very complicated. The process of stretching, over-rotation, and horizontal extrusion must be carried out continuously, and the force of horizontal extrusion cannot be removed before setting the shape, otherwise it will Gradually recover to Figure 7 , Figure 6 even Figure 5 In the state shown, all previous efforts have been for naught.
[0079] The following solution is another option, which can reduce the complexity of the folding process, but leaves the difficulty to the welding process. The specific steps are as follows:
[0080] 1) Cutting, the corrugated plate with upper plane, lower plane and slope surface (such as image 3 shown) cut into corrugated strips with upper plane, sloped plane and lower plane completely disconnected (such as Figure 4 shown);
[0081] 2) Welding is divided into the following four small steps,
[0082] a) separate the corr...
Embodiment 3
[0101] When the groove direction of the corrugated board is perpendicular to the running direction of the material, this dislocation connection folding process of complete cutting and partial welding has greater convenience.
[0102] In the cutting step, although the corrugated board is cut into corrugated slats, the cutting direction is consistent with the running direction of the corrugated board, so the cutting knife can cut the passing corrugated board into corrugated slats as long as the cutting knife rotates in situ, and the equipment is relatively Simple. Furthermore, corrugated slats are continuous in the direction of travel of the material and are relatively easy to handle.
[0103] As for the separation distance of the corrugated slats, excessive rotation, and horizontal extrusion operations, since the corrugated slats are continuous in the length direction, they can all be done at leisure and automatically completed when the material passes through. The structure o...
