[0021] Working principle: When processing the rolling, the rolling die 1 can be fixedly placed on a workbench of a device with a reciprocating impact head such as a punching machine. Then the plate surface of the sheet 4 is placed on the positioning surface of the guide block 12 for positioning, and the sheet 41 to be rolled is at least facing the contour rolling groove 111, and then the impact head of the punching machine can be used to hit the side of the sheet 4 away from the sheet 41 to be rolled, so that the sheet 4 moves toward the contour rolling groove 111 under the action of the punching machine, and during the movement of the sheet 4, the sheet 41 to be rolled is guided by the groove surface of the contour rolling groove 111, thereby completing the rolling.
[0022] Among them, preferably, before rolling, the plate 41 to be rolled of the plate 4 can be pre-bent on a bending machine so that the end of the plate 4 to be rolled 41 has a certain arc, so that the plate 4 can be rolled more smoothly on the rolling mold 1.
[0023] Please refer to Figure 2 As shown, further, a rotating shaft 2 is rotatably embedded on the positioning surface of the guide block 12, and part of the axial surface of the rotating shaft 2 protrudes from the positioning surface of the guide block 12, and the rotation direction of the rotating shaft 2 can guide the workpiece to move in the direction of the contoured rolling groove 111. Preferably, the rotating shaft 2 protrudes from the positioning surface of the guide block 12 by 1mm to 2mm. Most preferably, the rotating shaft 2 protrudes from the positioning surface of the guide block 12 by 1mm.
[0024] It can be seen from the above description that the rotation of the rotating shaft 2 can reduce the resistance of the sheet 4 on the rolling die 1, thereby facilitating the rolling of the sheet 4.
[0025] Please refer to Figure 2 As shown, further, the rotating shaft 2 is provided with limit blocks 21 at both ends along its own axis, and the limit blocks 21 can abut against the guide blocks 12 .
[0026] It can be seen from the above description that the limiting block 21 can prevent the rotating shaft 2 from falling off the guide block 12 .
[0027] Further, at least one of the limit blocks 21 is detachably connected to the rotating shaft 2. Preferably, the limit block 21 is threadedly connected to the rotating shaft 2.
[0028] It can be known from the above description that the rotating shaft 2 can be removed from the guide block 12 by disassembling the limit block 21 , so as to add lubricating oil to the connection between the rotating shaft 2 and the guide block 12 .

[0030] From the above description, it can be seen that the clamp 3 replaces the employee to grip the plate 4 and roll it on the punch press, wherein the plate 4 is clamped by the clamp 33, and the plate 4 is moved by the linear reciprocating device 31, so that each plate 41 to be rolled on the plate 4 is rolled one by one, and at the same time, when the impact head of the punch press moves while impacting the plate 4, the floating base 32 can move accordingly to avoid damage to the plate 4.
[0031] Please refer to Figure 2 As shown, further, the floating base 32 includes an assembly chassis 321, a guide column 322, a floating plate 323 and an elastic member 324; the assembly chassis 321 is arranged on the movable end of the linear reciprocating device 31, the guide column 322 is arranged on the assembly chassis 321, the floating plate 323 is slidably arranged on the guide column 322, the clamp 33 is arranged on the floating plate 323, and the elastic member 324 is compressed and arranged between the assembly chassis 321 and the floating plate 323.
[0032] From the above description, it can be seen that when the impact head of the punch press moves the impact plate 4, the plate 4 applies force to the floating plate 323 through the clamp 33, so that the floating plate 323 moves on the guide column 322, thereby further compressing the elastic member 324. When the impact head of the punch press removes the force on the plate 4, the elastic member 324 uses the elastic force to drive the floating plate 323 to reset, so that the linear reciprocating device 31 can drive the other plate 41 to be rolled of the plate 4 to be located at the rolling die 1 for rolling.
