DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] Reference Figure 1-Figure 4 , an automatic rolling forming and cutting machine, comprising a base 1, a rolling mechanism is arranged on the base 1, an L-shaped support block 2 is symmetrically fixedly installed on the base 1, a moving seat 3 is slidably placed on the upper ends of the two support blocks 2, a spring rod 4 is symmetrically fixedly installed on the moving seat 3, one end of the two spring rods 4 is respectively fixedly connected to the two support blocks 2, the rolling mechanism comprises a fixed plate 13 fixedly installed on the base 1, a plurality of rotating shafts 14 rotatably installed between the two fixed plates 13, a plurality of rolling rollers 15 respectively fixedly sleeved on the plurality of rotating shafts 14 and a driving device for driving the plurality of rotating shafts 14 to rotate simultaneously, and the plurality of rolling rollers 15 are divided into an upper and a lower layer;
[0023] When rolling the plate, the plate is inserted between the upper and lower layers of rolling rollers 15. The driving device can simultaneously drive multiple rotating shafts 14 to rotate, thereby driving multiple rolling rollers 15 to rotate. The upper and lower layers of rolling rollers 15 roll the plate and drive the plate to move toward the moving seat 3 at the same time.
[0024] A bracket 5 is fixedly installed on the movable seat 3, a telescopic cylinder 6 is fixedly installed on the bracket 5, and a shearing knife 7 is fixedly installed on the output end of the telescopic cylinder 6. When the plate moves below the shearing knife 7, the shearing knife 7 can be driven by the telescopic cylinder 6 to move vertically downward until the shearing knife 7 contacts the plate, thereby shearing the plate.
[0025] A connecting block 8 is fixedly installed at one end of the shearing knife 7, a rectangular block 9 is vertically slidably installed on the connecting block 8 through an elastic component, a moving rod 10 is horizontally fixedly installed at the lower end of the rectangular block 9, and a transmission component for driving the moving rod 10 to move is provided on the rolling mechanism;
[0026] A rectangular hole is sleeved on the rectangular block 9, the elastic component includes a vertical rod 11 fixedly installed in the rectangular hole and a telescopic spring 12 sleeved on the vertical rod 11, one end of the connecting block 8 is slidably sleeved on the vertical rod 11, and the two ends of the telescopic spring 12 are respectively fixedly connected to the surface of the connecting block 8 and the inner wall of the rectangular hole, and the transmission component includes a rotating disk 16 fixedly sleeved on the rotating shaft 14 and a plurality of rectangular clamping blocks 17 fixedly installed on the lower surface of the moving rod 10, and a plurality of rectangular clamping grooves 18 are opened on the rotating disk 16, and the rotating disk 16 is located directly below the moving rod 10;
[0027] When the shearing knife 7 approaches the plate, it will drive the connecting block 8 and the rectangular block 9 to move vertically downward, and then drive the moving rod 10 to move vertically downward through the rectangular block 9 until the multiple rectangular blocks 17 installed on the lower surface of the moving rod 10 contact the rotating disk 16, and the rotating disk 16 will rotate with the rotating shaft 14. During the rotation of the rotating disk 16, the rectangular slot 18 will engage with the rectangular block 17, thereby driving the moving rod 10 to move in the direction of the moving seat 3, and then drive the moving seat 3 to move in the direction of the spring rod 4 on the two supporting blocks 2 through the moving rod 10, and the spring rod 4 is compressed. As the shearing knife 7 continues to move downward, one end of the connecting block 8 will move vertically downward in the rectangular hole, and the telescopic spring 12 will be compressed. The shearing part of the shearing knife 7 and the plate moves forward together with the plate, thereby preventing the plate from bending and deforming at the part between the shearing knife 7 and the rolling mechanism, which affects the production quality of the product.
[0028] After the shearing is completed, the shearing knife 7 drives the moving rod 10 to separate from the rotating disk 16. At this time, under the action of the elastic force of the spring rod 4, the moving seat 3 moves to the initial position.
[0029] A slide bar 19 is vertically fixedly installed on the lower surface of the moving rod 10, and a connecting block 20 is fixedly installed on the side of the moving seat 3. A sliding hole is opened on the connecting block 20, and one end of the slide bar 19 is inserted into the sliding hole. When the moving rod 10 moves, the moving seat 3 can be directly driven to move through the slide bar 19 and the connecting block 20, so as to avoid the angle of the shearing knife 7 changing when the shearing knife 7 drives the moving seat 3 to move.
[0030] The upper ends of the two support blocks 2 are coated with lubricating oil, and the movable seat 3 is in sliding contact with the two support blocks 2. When the movable seat 3 moves on the upper ends of the two support blocks 2, the lubricating oil can reduce the friction between the movable seat 3 and the support blocks 2.
[0031] In the utility model, when the shearing knife 7 approaches the plate, the moving rod 10 is driven to move vertically downward through the elastic component, the connecting block 8 and the rectangular block 9, and then the moving rod 10 is driven to move in the direction of the moving seat 3 through the transmission component, and then the moving seat 3 is driven by the moving rod 10 to move in the direction of the spring rod 4 on the two supporting blocks 2, and the spring rod 4 is compressed. When the shearing knife 7 is in shearing contact with the plate, the shearing part of the shearing knife 7 and the plate moves forward together with the plate, thereby preventing the plate from bending and deforming at the part between the shearing knife 7 and the rolling mechanism, which affects the production quality of the product.
[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
