[0002] In order to efficiently utilize space, facilitate storage and transportation, and facilitate subsequent automatic feeding, the metal sheet is generally packaged into a coil after production in a compact winding form. This method significantly improves logistics efficiency.

[0003] However, during the handling, stacking and lifting of the coil, the significant risk brought by the self-weight is that if the coil is unevenly stacked, resulting in tilting or uneven force, or accidental falling, collision occurs during lifting operation, which is extremely easy to cause irreversible damage or deformation to the edge area of the coil. Such damage may manifest as local collapse, rolling, opening of the coil edge, or cause the entire edge to appear obvious undulating, bulging or even tearing. Such edge damage is extremely destructive, and its harmfulness lies in that it will directly damage the accuracy of all subsequent processing processes.

[0004] Edge damage or unevenness will seriously interfere with the stability of the sheet during uncoiling, flattening and running. In the final cutting link, the damaged or undulating edge will cause the material feed to shake and shift, making it difficult to accurately track the preset program, and inevitably causing the cutting edge to be irregular, the size to be out of tolerance, and the shape to be deformed.

[0036] The flattening roller structure 4 comprises two flattening rollers 41 arranged in parallel and side by side, and a feeding gap is arranged between the two flattening rollers 41;

[0037] Through the extrusion action of the upper and lower flattening rollers 41, the stress wrinkles remaining in the coil after uncoiling are preliminarily eliminated, and the coil is flattened to an approximately flat state, providing a basis for the accurate pressing of the subsequent spacing pressing device 5;

[0038] The spacing pressing device 5 comprises a base 51 and a pressing block 52, the bottom of the base 51 is fixed on the cutting platform 1, and the pressing block 52 is installed on the output shaft of the pressing cylinder 53;

[0039] The pressing cylinder 53 drives the pressing block 52 to move downward, and applies a concentrated pressure to the flattened coil, and the pressure value can be adjusted by the cylinder, so that the pressed coil forms a more flat plane due to plastic deformation.

[0040] The flat plane serves as a "temporary supporting surface" of the coil, offsets the deformation of the coil caused by its own bending stress, such as the natural sagging of the edge after uncoiling, so that the coil remains stable during cutting and avoids the cutting edge or burr caused by local bending.

[0041] The cutting device 7 comprises a lower blade 71 and an upper blade 72, and the lower blade 71 is located directly below the upper blade 72;

[0056] In this embodiment, the end of the lower blade edge 71 is provided with a discharging plate 9 for guiding the falling of the cut material.

[0057] Working principle:

[0058] 1. Unwinding and flattening of the material

[0059] The winding 3 releases the material under the action of the power, and the material enters the flattening roller structure 4 after passing through the winding support 2.

[0060] The upper and lower flattening rollers 41 press the material to eliminate internal stress wrinkles and flatten the material into an approximately flat state.

[0061] 2. Forming a support plane by spacing and pressing

[0062] The flattened material is conveyed to below the spacing and pressing device 5.

[0063] The pressing cylinder 53 drives the pressing block 52 to move downward, applies concentrated pressure to the material, and forms a more flat plane at the pressed position.

[0064] 3. Edge cutting and defect removal

[0065] When the front end of the material reaches the position of the edge cutting device 6, the upper cutting disc 611 and the lower cutting disc 612 of the cutting group 61 cooperate to perform rough cutting on the edge and remove burrs and defects caused by bending stress.

[0066] 4. Edge trimming to restore the flatness of the edge

[0067] The rough-cut material edge continues to be conveyed to the trimming group 62.

[0068] The upper trimming boss and the lower trimming boss of the trimming group 62 are pressed through the inclined surface to push the downward-bent edge upward after cutting, correct the shape, and restore the flatness of the edge.

[0069] 5. Precision cutting

[0070] The trimmed coil is conveyed to the cutting device 7.

[0071] The hydraulic cylinder 73 drives the upper blade 72 to move downward, and cooperates with the lower blade 71 to cut the coil, and the cut material falls into the discharge plate 9 and is guided and collected.

[0072] Based on the above, the present application can press the coil at equal intervals through a greater pressure after the coil is uncoiled, so that a more flat plane is formed at the pressed position, and the uncoiled coil has a more flat state through the plane as a support position of the coil still having bending stress.

[0073] From the common general knowledge, the present application can be realized through other embodiments without departing from the spirit or essential characteristics thereof. Therefore, the above disclosed embodiments are merely exemplary, and are not the only ones. All changes within the scope of the present application or equivalent to the scope of the present application are intended to be included in the present application.
