Preparation method of die-cutting knife edge with gradient function

Abstract

The invention discloses a preparation method of a die-cutting knife edge with a gradient function, and belongs to the technical field of laser cladding processing. The preparation method is characterized in that three cladding layers are cladded on the surface of a die-cutting knife by using a laser (1200 W-2000W) with stable cladding performance. The first layer is a base layer, the base layer is made of 100.00% of Ni60A powder, the three cladding layers are cladded, and two filling layers are cladded among the three cladding layers to form the base layer; the second layer is a dielectric layer, the dielectric layer is made of 87.20% of Ni60A powder, 6.60% of Co powder and 6.20% of WC powder, two cladding layers are cladded on the basis of the base layer, and a filling layer is cladded between the two cladding layers to form the dielectric layer; and the third layer is a tool nose layer, and the tool nose layer is made of 82.30% of Ni60A powder, 2.50% of Co powder and 15.20% of WC powder. According to the preparation method, and the existing laser cladding technology is controlled and improved, so that the laser cladding technology is suitable for preparing the die-cutting knife with the gradient function.

Description

technical field [0001] The invention belongs to the field of die-cutter tool processing, and in particular relates to a method for preparing a gradient function die-cutter blade. Background technique [0002] Die-cutting process is a cutting process in the post-processing of printed matter. Die-cutting process can make printed matter or other paper products into die-cutting knife plate for cutting according to the pre-designed graphics, so that the shape of printed matter is no longer limited to Straight sides and right angles. The die-cutting knife for die-cutting production can roll and cut the printed matter into the required shape under the action of pressure according to the product pattern. Such as bandages, masks, etc. The die-cutting knife is processed on the die-cutting roller with a diameter of 200-500mm, but the problem is that the blade is processed and fixed on the die-cutting roller. Once the blade is worn or damaged, it means that the entire die The cutting...

AI Technical Summary

Problems solved by technology

The die-cutting knife is processed on the die-cutting roller with a diameter of 200-500mm, but the problem is that the blade is processed and fixed on the die-cutting roller. Once the blade is worn or damaged, it means that the entire die Cutting rollers are scrapped together, resulting in great waste

Applying the controllability of laser cladding technology to the processing of die-cutting blades has broad prospects, but currently there is no effective solution for material selection and laser cladding methods
