[0002] The raw material for saw blade manufacturing is a steel strip with a required width, and the saw blade needs to be notched on the steel strip. At present, the equipment used for notching mainly includes stamping equipment and laser cutting equipment. The stamping equipment needs to use a die, and different tooth shapes correspond to different stamping dies, which has the problem of high cost. The laser cutting equipment can realize the cutting processing of various tooth shapes by programming the displacement trajectory of the cutting head. Therefore, the laser cutting processing equipment is gradually widely used in the notching processing field of saw blades.

[0003] Because the steel strip is long, the saw teeth on the steel strip are continuous, and therefore a large number of saw blade production lines appear on the market to continuously notch the steel strip. However, when the existing production line is used, the steel strip is thin, the temperature of the steel strip rises during laser cutting, and the steel strip is prone to warping deformation in the cutting area, resulting in bending stress of the notched steel strip, which needs to be corrected subsequently, reducing the production efficiency. The common solution is to use a pressure roller to extrude, but the contact area between the pressure roller and the saw teeth of the steel strip is small, which can cause incomplete correction. In addition, in the prior art, the steel strip needs to be limited to keep the steel strip centered during processing and conveying. However, because there are multiple structural parts on the production line, it is inconvenient to adjust them one by one. SUMMARY

After the clamping device 3 clamps the steel belt 9, it moves back and forth along the slide rail on the bed 1, and at the same time drives the first tooth plates 101 staggered on both sides to move. The first tooth plates 101 on one side of the slide 31 are provided with two rows at the upper and lower ends of the first gear 103. There is a gap between each row and they are connected by connecting rods 102, and the upper and lower rows of first tooth plates 101 are staggered, so that when the clamping device 3 moves from the feeding roller group 2 to the anti-warping roller group 8 position, the first gear 103 will experience multiple alternating upper and lower ends to engage with the first tooth plate 101, and the second gear 104 will also rotate back and forth. The second tooth plates 105 on both sides respectively drive the second pressure plate 122 to move up and down along the slide rod 123 and the mounting frame 121 to flatten the steel belt 9 passing through the middle position, because this method has a larger contact surface with the serrations on the side of the steel belt 9, and no matter whether the curved surface of the serrations is facing up or down, it can be flattened by the second pressure plate 122, thereby further strengthening the correction of the flatness of the steel belt 9.

[0042] When the device is used, the steel strip 9 is introduced from the upper feeding roller group 2 and passes through the clamping device 3, and then passes through the upper pressure roller 81 and the lower roller 82 on the anti-warping roller group 8. When adjusting the distance between the first limit plate 111 and the second limit plate 116, the positioning bolt 86 is unlocked, and the steel coil is guided by the inclined plate 112 into the first limit plate 111 of the feeding roller group 2. The guide rod 114 moves the compression spring 115 to maintain the limit on both sides of the steel coil. At the same time, the position of the second limit plate 116 and the remaining first limit plates 111 are adjusted synchronously to ensure The steel coil conveying and processing position is kept at the center of the bed 1. Because the vertical frame 88 and the connecting frame 89 on the top of the anti-warping roller group 8 slide along the movable slide 13, the position of the sawtooth cutting head 7 can be adjusted by the connecting frame 89 at the position of the slide 13 to keep it corresponding to the edge position of the steel coil. The positioning bolts 86 are pressed and contacted with the surface of the bed 1 to locate the positions of the first limit plate 111 and the second limit plate 116, and the anti-warping cylinder 84 is controlled to move, so that the upper pressure roller 81 and the lower roller 82 press the steel strip 9, and the Z The shaft cutting frame 6 moves horizontally, driving the sawtooth cutting head 7 to be located above the toothed part of the steel strip 9, and then controlling the sawtooth cutting head 7 to descend so that the laser emitter at its bottom is close to the steel strip 9, and then starting the production line, the clamping device 3 conveys the steel strip 9 downstream, and when the clamping device 3 moves from the feeding roller group 2 to the anti-warping roller group 8 position, the first gear 103 will experience multiple times of alternating upper and lower ends to mesh with the first tooth plate 101, and the second gear 104 will also rotate back and forth, and the second tooth plates 105 on both sides will respectively drive the second pressing plate 122 along The slide bar 123 and the mounting frame 121 move up and down to flatten the steel strip 9 passing through the middle position, because this method has a larger contact surface with the serrations on the side of the steel strip 9, and whether the curved surface of the serrations is facing up or down, it can be flattened by the second pressing plate 122, thereby further strengthening the correction of the flatness of the steel strip 9, and cooperating with the left and right translation of the Z-axis cutting frame 6 to continuously perform tooth opening processing on the steel strip 9. During this process, the dust removal fan 16 is started, and the dust removal fan 16 sucks away the smoke and dust generated in the tooth opening area, eliminating smoke and dust pollution.
