Description

Technical Field

[0001] The invention relates to the technical field of strip processing, in particular to a burr-free slitting device for high-frequency and high-magnetic-permeability ultra-thin metal strips. Background Art

[0002] High magnetic permeability tape is a metal material with excellent magnetic properties, usually made of iron-based alloys, specially used for electromagnetic applications. It has high magnetic permeability and low loss characteristics, which can effectively reduce energy loss and improve equipment efficiency. It is widely used in transformers, inductors, motors and other fields. In the production process of high magnetic permeability tape, a slitting device is needed to slit the high magnetic permeability tape.

[0003] The Chinese patent with the patent announcement number CN210172652U discloses an automatic leveling device for longitudinal cutting of a slitting machine, including a base, a bracket plate symmetrically fixed on the top of the base, an upper knife roller and a lower knife roller respectively arranged above the base, and both ends of the upper knife roller and the lower knife roller are respectively connected to the side wall of the adjacent bracket plate through bearings for rotation. The patent can realize the extrusion of the strip by setting a U-shaped plate, a first connecting plate, a second connecting plate, an upper pressure roller and a lower pressure roller. When the upper knife roller and the lower knife roller are slitting the strip, the vibration amplitude of the strip can be reduced, thereby preventing the curling and side bending of the slitting strip, and preventing foreign matter on the strip from sliding to the position of the upper knife roller and the lower knife roller, thereby reducing safety hazards. By setting a support platform, a servo motor, a threaded rod, a cross plate and a slide rod, the spacing between the upper pressure roller and the lower pressure roller can be adjusted, so it can adapt to strips of different thicknesses.

[0004] However, the current slitting processing device has the following problems: the slitting processing device is not convenient for processing the burrs generated on the edge of the high magnetic permeability strip after slitting. The high magnetic permeability strip becomes unstable due to the burrs during subsequent processing (such as winding), resulting in reduced processing efficiency and material waste. Therefore, we propose a burr-free slitting processing device for high-frequency, high magnetic permeability ultra-thin metal strips. Summary of the invention

[0022] The foreign body removal device 3 also includes a plurality of elastic telescopic plates 34, a plurality of hinged rods 35, a U-shaped connecting frame 36, a plurality of positioning rods 37, a plurality of slide plates 38, and a plurality of sharpening plates 39. The two ends of the U-shaped connecting frame 36 are fixed to the top of the U-shaped rod 25, and the cross bar of the U-shaped connecting frame 36 is located above the mounting plate 12. The fixed ends of the plurality of elastic telescopic plates 34 are evenly and equidistantly fixed to the bottom of the cross bar of the U-shaped connecting frame 36, and the elastic telescopic plates 34 penetrate the mounting plate 12.

Through grinding, the passivated part on the single circular knife of the slitting roller 13 can be removed, so that the single circular knife of the slitting roller 13 remains sharp, thereby improving the cutting effect and accuracy of the single circular knife of the slitting roller 13.

[0023] When in use, the high magnetic permeability metal strip passes through the guide roller of the single guide roller frame 16, the slitting knife roller 13 and the slitting groove roller 14 in turn, and the slitting knife roller 13 and the slitting groove roller 14 are driven to rotate by the driving gear box 11. The slitting knife roller 13 and the slitting groove roller 14 will slit the high magnetic permeability metal strip, and the slit high magnetic permeability metal strip will pass under the two guide rollers of the double guide roller frame 15 respectively. Then, the slit high magnetic permeability metal strip will pass over the guide rollers 22 corresponding to the two deburring devices 2 respectively. When the slit high magnetic permeability metal strip is transmitted, the telescopic grinding plate 24 will grind the edge of the slit high magnetic permeability metal strip. The telescopic grinding plate 24 can effectively remove the burrs on the edge of the high magnetic permeability metal strip and reduce The influence of irregular edges on subsequent processing is improved, and the neatness of the product is improved; at the same time, when the high magnetic permeability metal strip after slitting is transmitted, the guide roller 22 will be driven to rotate, and the guide roller 22 will drive the wave ring groove wheel 26 to rotate. The U-shaped rod 25 is restricted by the wave ring groove of the wave ring groove wheel 26. The wave ring groove of the wave ring groove wheel 26 will drive the U-shaped rod 25 to move back and forth up and down, and the U-shaped rod 25 drives the telescopic end of the telescopic grinding plate 24 to move back and forth up and down, so that the telescopic end of the telescopic grinding plate 24 dynamically grinds the high magnetic permeability metal strip after slitting up and down.

The V-shaped scraper 45 can reduce the chance of foreign matter re-contacting the pressure roller 43. It is worth noting that the side of the pressure roller 43 located in the middle of the V-shaped scraper 45 is the contact surface with the high magnetic permeability metal strip, while the side of the pressure roller 43 located on both sides of the V-shaped scraper 45 does not contact the high magnetic permeability metal strip; the foreign matter guided to both sides by the V-shaped scraper 45 will fall into the arc baffle 46, and the arc baffle 46 will block the foreign matter, thereby reducing the risk of secondary contamination of the pressure roller 43.
