A kind of manufacturing process of die-cutting knife plate

Abstract

The invention provides a die-cutting rule plate manufacturing process. The process includes steps: S1, designing and drawing drawings of a die-cutting rule plate, and performing laser cutting of the die-cutting rule plate according to the drawings; S2, processing the rule plate, to be more specific, shaping a die-cutting role, wherein a cutting edge angle of the rule plate is 60 degrees, a front angle of the rule plate is 25 degrees, and a rear angle of the rule plate is 10 degrees; S3, processing a die-cutting plate, to be more specific, polishing the surface of the die-cutting plate, and making a core plate groove and a core plate matched with the core plate groove in size on the die-cutting plate, wherein the core plate and the core plate groove are provided with positioning pin holes respectively, and the core plate is provided with a die-cutting rule groove; S4, mounting the rule plate, to be more specific, vertically fixing the rule plate into the die-cutting rule groove, putting the core plate in the core plate groove, and fixing through the positioning pin holes; S5, mounting material return sponge, to be more specific, adhering material return sponge to the rule plate. The die-cutting rule plate manufacturing process has advantages that a manufacturing process is scientific and reasonable, the manufactured die-cutting rule plate is long in service life, high cutting accuracy and great chip removal performance are realized, production efficiency is greatly improved, the rejection rate is decreased, and cost reduction is realized.

Description

technical field [0001] The invention belongs to the technical field of die-cutting knife plates, and in particular relates to a manufacturing process of die-cutting knife plates. Background technique [0002] In the field of die-cutting blade processing technology, the existing blades have low overall strength, low precision, and large deformation, resulting in unstable die-cutting quality of products, greatly increased scrap rate, and increased production costs. The temperature is high, if the heat dissipation is not good, it is easy to cause deformation of the blade and affect the quality of the molding; and during the cutting process, the blade is prone to knives, which will stick to the cardboard and affect the quality of the cardboard. At the same time, if the surface of the die-cutting board is not smooth enough, chips will stick to the die-cutting board, which will affect the positioning and cutting of the subsequent cardboard, resulting in deviations in molding.

Problems solved by technology

[0003] The purpose of the present invention is: for the above-mentioned existing die-cutting blade plate, the temperature of the blade is relatively high during the cutting process. If it does not dissipate heat well, it is easy to cause deformation of the blade and affect the molding quality; and during the cutting process, the blade Knives are prone to be formed on the surface of the die-cutting board, which will stick to the cardboard and affect the forming of the cardboard; at the same time, if the surface of the die-cutting board is not smooth enough, there will be chips sticking to the die-cutting board. Both positioning and cutting will be affected, which will lead to the problem of deviation in forming. The invention provides a production process of die-cutting knife plate
