[CN 201710658978.0] Disc shearing machine blade and preparation method thereof
[CN 201710658978.0] a disc shear blade and its preparation method title: a disc shear blade and its preparation method application number: CN 201710658978.0 applicant: antai science and technology co., ltd. application date: 2017-8-4 patent type: invention application the present invention relates to the field of preparation of mechanical blades. In order to provide a disc cutter blade with high cost performance for cutting stainless steel and high strength steel plates, the present invention proposes a method for preparing a disc cutter blade, in which a blade base body is prepared and a blade sheath is covered outside the blade base body, and alloy powder is filled between the outer side wall of the blade sheath and the outer side wall of the blade base body through a powder filling channel located on the annular cover plate on the blade sheath, after filling and vibrating, install the top cover on the powder loading channel; place the blade package with the blade matrix and alloy powder in a degassing furnace for vacuum evacuation and degassing and heat preservation, place it in a hot isostatic pressing furnace for hot isostatic pressing treatment to form a blade edge layer; remove the blade package by machining to obtain the blade blank, and then carry out annealing treatment, quenching treatment and tempering treatment in sequence, and finish machining to obtain the blade. The blade prepared by the method has uniform thickness and wear resistance, long service life, low cost and high cost performance.
