Abstract

A process for preparing the moulding-cutting roller, pressing-cutting roller or indentating roller includes making raw roller with carbon steel or alloy steel, preparing high-V alloy steel powder from V, C, Mn, Si, Cr, Mo, S and Fe, laser coating of said powder on the surface of raw roller, grinding and electrospark linear cutting to shape the cutting edges.

Description

(1) Technical field [0001] The invention relates to a method of laser cladding on the surface of a roller using low-carbon steel, medium-carbon steel, high-carbon steel, low-carbon alloy steel, medium-carbon alloy steel or high-carbon alloy steel as a blank, in particular to a die-cutting roller, The manufacturing method of pressure-cutting or creasing rollers with temperature-controlled laser surface powder metallurgy coating, which is used to manufacture high-vanadium alloy steel blades on the rollers. (2) Background technology [0002] Existing die-cutting rollers, pressure-cutting rollers or creasing rollers are all made of high-carbon or high-alloy steel, which has high material costs, complicated machining and heat treatment processes, low service life, and product quality problems. The laser cladding method is a new technology, which can greatly reduce the material cost and improve the service life of the roller. However, laser surface powder metallurgy coating has a...
