By rotating the hand wheel, the side tightening block 481 is driven to tighten the fine-tuning slot block 473 from the side.

[0123] Based on the structural description of the above device, the complete working process of this device is as follows:

[0124] First, the plate to be processed is loaded through the guide device 2. The guide device 2 mainly includes a guide support plate and a pressure wheel. A loading channel for the plate to be processed is formed between the guide support plate and the pressure wheel. The width of the loading channel is adjusted according to the width of the feed plate in the actual production process. The adjustment method is as follows: start the guide drive motor 23 to drive the first ball screw 24 to rotate, thereby driving the second guide support plate 22 to move along the length direction of the first horizontal mounting rod 30, and then adjusting the width of the loading channel formed by the second guide support plate 22 and the first guide support plate 21. During the movement of the second guide support plate 22 along the length direction of the first horizontal mounting rod 30, the second pressure wheel 26 is driven to move horizontally synchronously;

[0125] Secondly, after the head end of the sheet to be processed reaches the preset bending processing position, the material loading is stopped. At this time, the head end of the sheet to be processed needs to be fixed and pressed by the end head positioning structure 43 to improve the stability of the subsequent folding operation. The pressing method is as follows: the end head lifting unit is used to drive the head translation unit and the end head pressing strip 431 to move, and the end head pressing strip 431 is used to press the head end of the sheet to be processed. In the actual process, the horizontal position of the end head pressing strip 431 can be adjusted by the end head translation unit according to the part that needs to be pressed;

[0126] Finally, the folding operation is carried out, which involves the upper pressure plate device 4 and the flip plate device 3 mentioned in this scheme. The flip plate device 3 is arranged below the upper pressure plate device 4, and the upper pressure plate device 4 and the flip plate device 3 cooperate to realize the folding operation of the plate to be processed. The specific working process is as follows: when the head end of the plate to be processed is pressed by the end pressure strip 431, the first oil cylinder 111 arranged on the cylinder seat 11 is used to drive the upper pressure plate device 4 to move downward. After reaching the preset position, the first oil cylinder 111 stops moving, and the flip plate cylinder 33 is used to drive the flip plate 32 to flip, and the flip plate 32 is used to cooperate with the pressure foot of the upper pressure plate device 4 to complete the folding operation;

[0127] Among them, during the folding process, it is necessary to adjust the upper pressing plate device 4 according to the specific folding width. The upper pressing plate device 4 of this solution is provided with an upper die mechanism 46. The upper die mechanism 46 includes a fixed end presser foot 461 and at least one movable end presser foot. This solution takes two movable end presser feet as an example, namely a first movable end presser foot 462 and a second movable presser foot:

[0128] The effective presser foot widths of the fixed end presser foot 461 and the first movable end presser foot 462 are set to be the same, and the effective presser foot widths of the fixed end presser foot 461 and the second movable end presser foot are set to be different. Assume that the width of the fixed end presser foot 461 is X, the width of the second movable end presser foot 463 is Y, and X is greater than Y.

[0129] There are two combination modes. One is a combination of a fixed end presser foot 461 and a first movable end presser foot 462. The first movable end presser foot 462 is driven by the servo system to move along the mounting groove 47. When the first movable end presser foot 462 moves to the outermost side and is flush with the outer side of the fixed end presser foot 461, the minimum width X can be achieved. When the first movable end presser foot 462 moves to the innermost side of the fixed end presser foot 461, the maximum width 2X of this mode is achieved.

[0130] The other is that the fixed end presser foot 461 does not move, the first movable end presser foot 462 and the second movable end presser foot 463 move together, the first movable end presser foot 462 and the second movable end presser foot 463 are respectively controlled step by step by the servo system, and the servo system is distributed on both sides of the presser foot. When the first movable end presser foot 462 moves to the outermost side and is flush with the outer side of the fixed end presser foot 461, the first movable end presser foot 462 and the second movable end presser foot 463 are combined, and this is the minimum width X+Y of this mode. The first movable end presser foot 462 moves to the innermost side of the fixed end presser foot 461, and the first movable end presser foot 462 and the second movable end presser foot 463 are combined to form the maximum width 2X+Y of this mode.

[0131] The combination of the above two modes can achieve stepless adjustment of the width from X to 2X+Y.

[0132] At the same time, the sharp corner of the fixed end presser foot 461 is combined with the first movable end presser foot 462 and the sharp corner to form a new sharp corner, and the sharp point position remains unchanged from the respective sharp point positions, so that the bending radius can be kept consistent during processing.

[0133] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
