Embodiment Construction

[0021] The invention starts from two aspects of matrix powder composition and saw blade preparation process, and focuses on improving cutting performance and reducing cost. The saw blade cutter head of the present invention adopts a copper base carcass, adds a small amount of tin powder, cobalt powder, and alloys carcass powder with a total weight of 10 kg, and the ratio of carcass powder and diamond is shown in Table 1. The composition involved in the concrete implementation case of the present invention is as shown in table 1:

[0022] Table 1

[0023]

[0024] Diamond tool of the present invention is manufactured according to the following steps:

[0025] (1) Mixing

[0026] Mix Cu, Sn, Co powder and diamond according to the weight ratio in Table 1 to obtain alloy carcass powder, and dry mix them in a three-dimensional mixer for 1 to 2 hours. In the mixing process, pour 5wt% granulating agent into the mixer, the composition of the granulating agent is: paraffin and ga...

Abstract

The invention relates to a super-hard tool and a preparation method thereof in the field of powder metallurgy, in particular to a marble cutting saw blade and a preparation method thereof. The saw blade comprises a matrix (1) and a tool bit (2), wherein the tool bit (2) is formed by mixing, thermally pressing and then sintering the matrix powder and the diamond particle; the component of the matrix powder includes 65 to 75 wt% of Cu, 10 to 20 wt% of Sn and 5 to 20 wt% of Co; and the weight of the diamond particle is 2 to 2.5 wt% of that of the matrix powder. The diamond saw blade is prepared after the steps of batching materials, mixing materials, cold press moulding, hot press moulding and subsequent treatment. Compared with the similar products, the Cu-base alloy diamond saw blade of the invention prolongs 1 to 3 times of the service life and reduces 30 to 50% of the cost on the premise of ensuring the constant sharpness and saw-cutting flatness.

Description

technical field [0001] The invention relates to a superhard tool in the field of powder metallurgy and a preparation method thereof, in particular to a marble cutting saw blade and a preparation method thereof. Background technique [0002] In the prior art, diamond saw blades generally adopt cobalt-based carcass formula. The cobalt-based carcass has stable performance and good toughness, but cobalt is expensive, and the increase in cobalt content will increase the cost. At the same time, the common saw blades for cutting marble on the market are generally prepared by high-frequency welding process. Due to the high cost of raw materials and the limitation of the preparation process, the diamond saw blade obtained by adopting such cobalt-based matrix and high-frequency welding process has relatively high product cost and short service life. Contents of the invention [0003] The object of the present invention is to provide a marble cutting saw blade with low price, long s...
