Problems solved by technology

[0003] Diamond saw blades are mostly used in the actual cutting process. The main performance indicators of diamond saw blades include high strength, wear resistance, and corrosion resistance. The current technology has basically solved the problem of corrosion resistance, but However, there are big problems in strength and wear resistance, which lead to short service life of diamond saw blades and affect the cutting effect. To solve the problem of strength and wear resistance of diamond saw blades, we must not only start from its raw material formula, but also It is important to improve its production process, as well as the various equipment used in the production process, are direct factors affecting the performance of diamond saw blades, and according to the existing diamond production process, there are still many problems that need to be improved. aspect

Embodiment 1

[0038] Embodiment 1: A high-strength diamond dry wave saw blade, the diamond saw blade includes main materials according to the volume fraction: 12% diamond, 25% copper, 40% iron, 8% tin, 5% nickel, 5% cobalt and auxiliary materials Alloy powder 5%.

[0039] A high-strength diamond dry wave saw blade cold press forming process, comprising the following steps:

[0040] (1) Ingredients: select the main materials diamond, copper, iron, tin, nickel, cobalt and alloy powder according to the volume fraction ratio, and reserve;

[0041] (2) Screening: The ingredients prepared in step (1) are sequentially passed through 35, 40, and 45 mesh screens for three-stage screening; after three-stage screening, uniform powder particles that meet the requirements are screened out;

[0042] (3) Pre-mixing: Pre-mixing mechanism 1 is used to mix iron and cobalt first. The purpose of mixing iron and cobalt now is that the fluidity of iron is good, and cobalt is not easy to mix evenly, so it is nec...

Embodiment 2

[0055] Embodiment 2: A high-strength diamond dry wave saw blade, the diamond saw blade includes main materials according to the volume fraction: 15% diamond, 20% copper, 45% iron, 3% tin, 8% nickel, 6% cobalt and auxiliary materials Alloy powder 3%.

[0056] The difference with the technique of embodiment one is:

[0057] (3) Pre-mixing: Mix for 35 minutes. After the iron and cobalt are mixed, add the remaining diamond, copper, tin, nickel and alloy powder from the feeding equipment of the pre-mixing mechanism at the same time. The feeding speed of copper is set to diamond feeding. 1.5 times the speed of the material, the pre-mixing time of the dry material is 5h;

[0058] (4) Total mixing: use the total mixing mechanism 2, add wetting agent to the dry material pre-mixed in step (3), stir evenly, and the wetting time is 2.5h;

[0059] (5) Cold pressing: prepare the mold, install the matrix in the mold before cold pressing, and add the mixed material to the mold of the cold p...

Embodiment 3

[0065] Embodiment 3: A high-strength diamond dry wave saw blade, the diamond saw blade includes main materials according to the volume fraction: 14% diamond, 22% copper, 42% iron, 4% tin, 6% nickel, 8% cobalt and auxiliary materials Alloy powder 4%.

[0066] The difference with the technique of embodiment one is:

[0067] (3) Pre-mixing: Mix for 30 minutes. After the iron and cobalt are mixed, add the remaining diamond, copper, tin, nickel and alloy powder from the feeding equipment of the pre-mixing mechanism at the same time. The feeding speed of copper is set to diamond feed. 1.5 times the speed of the material, the pre-mixing time of the dry material is 5h;

[0068] (4) Total mixing: use the total mixing mechanism 2, add wetting agent to the dry material pre-mixed in step (3), stir evenly, and the wetting time is 2.5h;

[0069] (5) Cold pressing: prepare the mold, install the matrix in the mold before cold pressing, and add the mixed material to the mold of the cold pres...

Abstract

The invention discloses a high-strength diamond dry corrugated saw blade and a cold press molding technology thereof. The diamond saw blade comprises the following main materials according to volume fractions: 12-15% of diamond, 20-25% of copper, 40-45% of iron, 3-8% of tin, 5-8% of nickel, 5-8% of cobalt and 3-5% of alloy powder as an auxiliary material. A method for producing the diamond saw blade mainly comprises the following steps: batching, sieving, pre-mixing, total mixing, cold press molding, sintering, cooling, surface treatment, paint spraying, edging and the like. The strength and the wear resistance of the diamond saw blade produced by the formula and the technology of the invention are improved, the service life is prolonged in an actual using process, the production cost is saved greatly, resources are saved, and the technology is environmentally friendly, sanitary and safe in a production process.

Description

technical field [0001] The invention relates to a diamond saw blade, in particular to a cold-press forming process of a high-strength diamond dry corrugated saw blade. Background technique [0002] Diamond saw blade is a cutting tool, which is widely used in the processing of hard and brittle materials such as concrete, refractory materials, stone, and ceramics. Diamond saw blades are mainly composed of two parts; the base body and the cutter head. The substrate is the main supporting part of the bonded cutter head, while the cutter head is the part that cuts during use. The cutter head will be continuously consumed during use, but the substrate will not. The reason why the cutter head can cut The role of diamond is because it contains diamond, which is currently the hardest substance, and it rubs and cuts the processed object in the cutter head. The diamond particles are wrapped in metal inside the cutter head. [0003] Diamond saw blades are mostly used in the actual cu...
