Embodiment Construction

[0013] A circular knife for stamping nanocrystals, see figure 1 : It includes a blade part 10 and a blade part 20, the blade part 10 protrudes outward from the blade part 20, the blade part 10 includes a blade 1 with a thickness of 0.008 mm to 0.012 mm, and one end face of the blade 1 has two directions of thickness. The outer slope is set at 4°-6°, the other end surface 3 of the blade thickness is inclined outward at 24°-26°, and the hardness of the entire blade part 10 is 66HRC-68HRC.

[0014] The material of the entire round knife 100 is specifically S290 steel, which is high-hardness, high-wear-resistant powder high-speed steel. The chemical composition and mass percentage ratio of the S290 steel is as follows: carbon C: 2.01%, tungsten W: 13.0%, cobalt Co: 11.0%, Chromium Cr: 3.75%, molybdenum Mo: 2.45%, vanadium V: 5.05%, and the rest is iron Fe;

[0015] The round knife 100 is made into a finished product after being processed by a heat treatment process for five days ...

Abstract

The invention provides a circular cutter for stamping nanocrystal. Through the width of a thickened cutter point of the circular cutter, the hardness of materials is improved, and the cutter point isoffset relative to the thickness of the overall circular cutter, so that the cutter body stability is improved; and the life of the circular cutter is prolonged, and machined nanocrystal is free of cracks and magnetic loss. The circular cutter comprises a cutting edge part and a cutter body part, and the cutting edge part protrudes out of the cutter body part; the cutting edge part comprises the cutter point with the thickness of 0.008 mm-0.012 mm, and one end of the thickness of the cutter point is inclined outwards at 4-6 degrees; the other end of the thickness of the cutter point is inclined outwards at 24-26 degrees; and the hardness of the whole cutting edge part is 66 HRC-68 HRC.

Description

technical field [0001] The invention relates to the technical field of nanocrystal cutting, in particular to a circular knife for stamping nanocrystals. Background technique [0002] The internal structure of nanocrystals is metal particles, and the main component is iron element with high hardness. The material of the existing knife die for cutting nanocrystals is GC53 with low hardness. left and right, unable to meet the needs of mass production, and the two sides of the existing round knife are arranged symmetrically with respect to the vertical plane of the blade. There are cracks. Contents of the invention [0003] In view of the above problems, the present invention provides a round knife for stamping nanocrystals, the thickened blade width improves the hardness of the material, and the blade is offset relative to the thickness of the overall round knife, which improves the stability of the blade , so that the life of the round knife is increased, and the processed...
