DETAILED DESCRIPTION
[0024] The present invention is described below with specific examples, but is not intended to be limiting of the invention.
[0025] Example 1
[0026] like Figure 1-Figure 7As shown, in this embodiment, a metal sheet cutting device for automobiles is provided, comprising a conveyor body 1 for conveying a sheet 15 and a cutting device installed on the conveyor body 1 for cutting the sheet 15. The sheet 15 can move along the conveying direction of the conveyor body 1 on the conveyor body 1. After moving to a specific position, it is cut by the cutting device. The cutting method is generally end cutting. Support blocks 2 are fixed on both sides of the conveyor body 1. A conveying channel 4 for the movement of the sheet 15 is provided inside the conveyor body 1. A plurality of horizontally arranged and rotatable driving rollers 5 are provided inside the conveyor channel 4. The contact position between the driving roller 5 and the sheet 15 is The arrangement has an anti-slip function. During the rotation, the driving roller 5 can drive the plate 15 to move along the conveying direction inside the conveying channel 4. The lower ends of the multiple driving rollers 5 form a molding surface. The upper surface of the plate 15 is in contact with the molding surface and moves on the molding surface. The surface of the plate 15 in contact with the molding surface is the positioning surface for processing. The positioning surface provided in this embodiment is the upper surface of the plate 15. When the above surface is the positioning surface, the positioning position during cutting can be made more accurate. Compared with the conventional method of using the bottom surface as the positioning surface, the thickness of the plate 15 can be ignored, and there is no need to readjust the positioning position due to the different thickness of the plate 15.
[0027] The bottom of the plate 15 is provided with a clamping device that can press the plate 15 against the forming surface, and the clamping device can apply a clamping force to the plate 15, and the clamping force ensures that the workpiece is always in contact with the forming surface. Under the premise that there is friction between the driving roller 5 and the plate 15, the driving roller 5 can drive the plate 15 to move when it rotates. A gap is left between two adjacent driving rollers 5, and the cutting device can pass through one of the gaps and contact the plate 15. Both ends of the driving roller 5 are rotatably mounted on both sides of the conveying channel 4 through a rotating wheel 18. Multiple rotating wheels 18 on one side are connected to each other by a hinge 21. A motor for driving one of the rotating wheels 18 to rotate is fixed on the conveying body 1. A rotatable pre-tightening roller 6 is installed at the bottom of the driving roller 5. The pre-tightening roller 6 can apply a pushing force to the workpiece. The pre-tightening roller 6 is arranged symmetrically on the left and right. The pre-tightening rollers 6 on both sides are rotatably mounted on the side walls of the conveying channel 4 respectively. A gap is left between the pre-tightening rollers 6 on both sides, and a positioning body 13 can be installed between the two gaps. The positioning body 13 can be in various forms. The most common one is connected to the output shaft of the oil cylinder. The oil cylinder is installed inside the conveyor body 1. When the output shaft of the oil cylinder is extended, the positioning body 13 blocks the front end of the plate 15 to position the plate 15. The gap left between the pre-tightening rollers 6 on both sides can also ensure that the workpiece is easier to fall. Vertical grooves are provided on both sides of the conveying channel 4. Side bodies 19 are slidably installed in the vertical grooves through elastic bodies 20. The elastic body 20 is connected to the bottom of the side body 19. The pre-tightening roller 6 is rotatably installed on the side body 19. Under the action of the pre-tightening roller 6, the plate 15 will be exerted with a pressure. Under the action of the pressure, the plate 15 will always be in contact with the driving roller 5. When the driving roller 5 rotates, it can drive the plate 15 to move. A pushing cylinder is installed at the bottom of the transmission channel 4. A clamping plate 24 is installed at the output end of the pushing cylinder. The clamping plate 24 can exert pressure on the plate 15. Under the action of the pushing cylinder, the clamping plate 24 will exert a clamping force on the plate 15. When cutting is required, this clamping force will fix the plate 15 to prevent the plate 15 from shaking.
[0028] The cutting device includes a cutting saw 12 capable of cutting a plate 15. The cutting saw 12 can move up and down and can move horizontally along the cutting direction. The cutting direction can be distributed at an angle to the moving direction of the plate 15. In this embodiment, only the case where the cutting direction and the moving direction are at a 90-degree angle is provided. When the cutting saw 12 moves downward to contact the plate 15, the plate 15 is in a fixed state. The up and down movement of the cutting saw 12 does not cut the plate 15. The plate 15 will only be cut when it moves along its horizontally arranged cutting direction. The lowermost end point of the cutting saw 12 forms a horizontally arranged axis a with the plane where the cutting saw 12 is located. The cutting saw 12 can rotate along the axis a. The cutting saw 12 can change the angle between it and the surface of the workpiece and cut it, thereby The cutting device can cut an oblique incision and change its cutting angle as needed. The cutting device includes a support body 7 that can move along the cutting direction. The support body 7 drives the cutting saw 12 to move. The bottom of the support body 7 is provided with an arc surface. The axis of the arc surface coincides with the axis a. The cutting saw 12 is installed inside the support shell, and the support shell is rotatably installed on the arc surface. When the axis of the arc surface coincides with the axis a, the support shell drives the cutting saw 12 to rotate, and the rotating shaft always coincides with the axis a. When the cutting device moves downward, the position where the axis a contacts the forming surface is the positioning position. The axis a can move according to the up and down movement of the cutting device and the cutting saw 12. The cutting saw 12 rotates along the axis a, which can ensure that an oblique incision is cut without changing the positioning position of the cutting saw 12.
[0029] The support shell includes an arc plate 10 and a support plate 23 installed in the center of the arc plate 10. The cutting saw 12 is rotatably installed inside the support plate 23 and a part of the cutting saw 12 extends out of the support plate 23. The extended part can cut the plate 15. A driving motor 11 is fixed on the support plate 23 to drive the cutting saw 12 to rotate. The arc surface of the arc plate 10 is in contact with the arc surface of the bottom of the support body 7. An arc-shaped slide 22 is provided on the arc plate 10, and a slide groove is provided on the arc surface. The slide 22 is slidably installed in the slide groove. The connection between the slide 22 and the slide groove ensures that the arc plate 10 can always be in contact with the arc surface of the bottom of the support body 7. A rack 9 is fixed on the arc plate 10, and the rack 9 extends to the inside of the support body 7. A first gear 8 meshing with the rack 9 is rotatably installed inside the support body 7. A motor for rotating the first gear 8 is fixed on the support body 7. The rotation of the first gear 8 can drive the arc plate 10 to rotate along the axis a, thereby tilting the cutting saw 12 and cutting a bevel on the plate 15.
[0030] Example 2
[0031] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6The present embodiment provides a specific moving method of the cutting device based on the first embodiment, and the specific details are as follows: the cutting device is slidably mounted on the slide 3, and a slider 14 is fixed on the support body 7. A groove is provided inside the slide 3, and the slider 14 is slidably mounted in the groove. A screw rotates in the groove, and a screw hole is provided inside the slider 14. The screw passes through the screw hole. When the screw rotates, the slider 14 can move in the groove. A motor for driving the screw to rotate is installed on the slide 3, and the slide 3 is mounted inside the support block 2 by sliding up and down through the slides 16 on both sides. One of the side walls of the slide 16 is provided with teeth, and a second gear 17 is rotatably mounted inside the support block 2. The second gear 17 is engaged with the teeth, and a motor that drives the second gear 17 to rotate is fixed on the support block 2. When the second gear 17 rotates, it can drive the slide 3 to move up and down through the slide 16, and the support body 7 is slidably mounted on the slide 3.
[0032] Working principle: When working, one end of the long strip of plate 15 is inserted between the driving roller 5 and the pre-tightening roller 6. The driving roller 5 rotates, and the pre-tightening roller 6 presses the plate 15 against the driving roller 5. The driving roller 5 rotates to drive the plate 15 to be transported. When the plate 15 moves to a suitable position, the angle between the cutting saw 12 and the plate 15 is adjusted as needed. When the cutting saw 12 is tilted, an oblique cut can be made at the end of the plate 15. When the cutting saw 12 is perpendicular to the plate 15, a straight cut can be made at the end of the plate 15. After adjusting the angle, the cutting saw 12 moves to the right position. The cutting work can be completed by moving from one side of the plate 15 to the other side. The length of the workpiece is positioned on the forming surface. The tilting of the cutting saw 12 will not change the cut length. The thickness of the cutting saw 12 can be corrected by the blade compensation of the cutting saw 12, so the thickness of the cutting saw 12 can be ignored. After the cutting is completed, the plate 15 can be conveyed out by the conveying channel 4. The cutting device has the function of cutting different shapes of incisions on the plate 15, and there is no need to consider the thickness of the plate 15, which saves positioning time and improves work efficiency.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
