The opposite surfaces of the two sliding blocks 15 are rotatably connected with upper calibration rollers 12.

[0033] Among them, the upper surface of the base 1 is fixedly connected to the support frame 3, and the support frame 3 is in an inverted "U" shape. The upper surface of the outer wall fixing plate at the lower end of the support frame 3 is fixedly connected to the first motor 2. The lower end of the support frame 3 is internally rotatably connected to the lower pressure roller 9.

[0034] Furthermore, when using the device, it is started by connecting an external power supply, firstly, the rotating block 21 is twisted to rotate and drive the rotating threaded rod 16 to rotate while driving the sliding block 15 to move up and down, then the sliding block 15 moves up and down to drive the upper calibration roller 12 to move up and down to adjust the distance between the upper calibration roller 12 and the lower calibration roller 13, so as to adjust according to the thickness of the material, then the material is passed through the upper calibration roller 12 and the lower calibration roller 13 for rough positioning, so that the material is subjected to a certain pressure and begins to be initially formed, and then the output end of the cylinder 17 moves in the opposite direction to drive the guide plate 10 to move in the opposite direction while adjusting the distance according to the width of the material. , then the material is transported to the upper surface of the lower pressing roller 9 through the cooperation of the conveying roller 11 and the guide plate 10, and then the output end of the second motor 5 rotates through the transmission wheel 7 and the transmission belt 6 to drive the threaded rod 19 to rotate, and then the threaded rod 19 rotates to drive the sliding seat 4 to move downward while driving the upper pressing roller 8 to move downward. At the same time, the lower pressing roller 9 is rotated through the output end of the first motor 2, so that the upper pressing roller 8 moves downward to press the material on the lower pressing roller 9, so that when the material passes through the lower pressing roller 9 and the upper pressing roller 8, it is restricted by the shapes of the lower pressing roller 9 and the upper pressing roller 8, resulting in continuous plastic deformation and finally forming a predetermined shape.

[0035] By twisting the rotating block 21 in the guide calibration device, the distance between the upper calibration roller 12 and the lower calibration roller 13 can be adjusted according to the thickness of the material, so that the material is subjected to a certain pressure and begins to be initially formed. Then, the cylinder 17 can adjust the distance between the two guide plates 10 according to the width of the material, so that the material is effectively placed to offset during feeding, effectively improving the quality of material forming, while reducing the scrap rate, thereby effectively improving the practicality of the equipment. The output end of the second motor 5 rotates through the transmission wheel 7 and the transmission belt 6 to drive the threaded rod 19 to rotate, and then the threaded rod 19 rotates to drive the sliding seat 4 to move downward while driving the upper pressure roller 8 to move downward. At the same time, the lower pressure roller 9 is rotated through the output end of the first motor 2, so that the upper pressure roller 8 moves downward to press the material on the lower pressure roller 9. In this way, the distance between the lower pressure roller 9 and the upper pressure roller 8 can be adjusted according to the thickness of the material, effectively improving the flexibility of the equipment, while reducing the workload of the staff and improving the work efficiency of the staff.

[0036] Working principle: First, twist the rotating block 21 to rotate and drive the rotating threaded rod 16 to rotate while driving the sliding block 15 to move up and down. Then the sliding block 15 moves up and down to drive the upper calibration roller 12 to move up and down to adjust the distance between the upper calibration roller 12 and the lower calibration roller 13. This is adjusted according to the thickness of the material. Then the material is roughly positioned between the upper calibration roller 12 and the lower calibration roller 13. In this way, the material is subjected to a certain pressure and begins to be initially formed. Then, the output end of the cylinder 17 moves in the opposite direction to drive the guide plate 10 to move in the opposite direction while adjusting the distance according to the width of the material. Then, it passes through the conveyor roller 1 1 and the guide plate 10 cooperate to transport the material to the upper surface of the lower pressing roller 9, and then the output end of the second motor 5 rotates through the transmission wheel 7 and the transmission belt 6 to drive the threaded rod 19 to rotate, and then the threaded rod 19 rotates to drive the sliding seat 4 to move downward while driving the upper pressing roller 8 to move downward. At the same time, the lower pressing roller 9 is rotated by the output end of the first motor 2, so that the material is pressed on the lower pressing roller 9 by the downward movement of the upper pressing roller 8, so that when the material passes through the lower pressing roller 9 and the upper pressing roller 8, it is restricted by the shapes of the lower pressing roller 9 and the upper pressing roller 8, resulting in continuous plastic deformation and finally forming a predetermined shape.

Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
