Problems solved by technology

[0002] At present, there are two main types of matrix formulas for marble cutter heads. One type has only two elements, Cu and Sn. This type of matrix is ​​hard and brittle, has low wear resistance, and is sharp when cutting, but has a short lifespan.
The other is to add Fe

specific Embodiment 1

[0031] Specific embodiment 1, a kind of high-life marble cutter carcass, formula composition is made up of following percentage by weight: Cu-Sn-Si alloy 18%; Cu-Zn alloy 12%; Ni 12%; Cu-Sn alloy 58%.

specific Embodiment 2

[0032] Specific embodiment 2, a long-life marble cutter head carcass, the formula components are composed of the following weight percentages: Cu-Sn-Si alloy 25%; Cu-Zn alloy 15%; Ni 15%; Cu-Sn alloy 45%.

[0033] Carcass formula feature of the present invention is set forth below:

[0034] 1. Cu-Sn-Si alloy is a new type of high brittle powder. The addition of non-metallic Si increases the brittleness of the matrix, which can increase the height of the diamond edge and improve the sharpness of the product.

[0035] 2. The low-melting point elements Sn and Zn in the formula are added in the form of alloys. During sintering, the sintering range is wider, which can effectively control the loss of low melting point. The low melting point in the carcass is added in an alloy form and the carcass Ni is added together, which can relax the requirements for welding materials, and can use welding materials with lower silver content for welding, which can reduce welding costs.

Embodiment 1

[0053] A method for making a high-life marble cutter head, the steps are as follows:

[0054] 1) The carcass powder material is weighed according to the proportion, and stirred for 60 minutes with a three-dimensional mixer; the formula components of the carcass powder material are composed of the following weight percentages: Cu-Sn-Si alloy 18%; Cu-Zn alloy 12%; Ni12 %; Cu-Sn alloy 58%;

[0055]2) Use copper-coated diamonds with a content of 50% in 60 / 70 and 50% in 70 / 80, mix them thoroughly with a splitter, then add 3‰ of paraffin into the diamond, and mix by hand for 3 minutes;

[0056] 3) Mix 98% of the carcass powder and 2% of the diamond by weight, and mix them in a mixer for 45 minutes to obtain a compound of the carcass and the diamond;

[0057] 4) In the multi-layer automatic cold pressing machine, the mixture is pressed into a cutter body, and the cold pressing pressure is 1000kg / cm2.

[0058] 5) Put the green body into a multi-layer graphite mold and carry out sint...

Abstract

The invention discloses a high-service-life marble cutter head blank body and a manufacturing method of a cutter head. The high-service-life marble cutter head blank body comprises the following components, in percentage by weight, of 15%-25% of Cu-Sn-Si alloy, 10%-20% of Cu-Zn alloy, 10%-20% of Ni and 35%-65% of Cu-Sn alloy. According to the cutter head blank body, due to the introduction of specific new materials and the reasonable allocation among all components, the brittleness, the wear resistance and the toughness of the blank body are more reasonably fused, the universality of the blankbody is effectively enhanced, the diamond cutter head can be suitable for cutting various types of marble, and the service life is prolonged by 20%-30% under the condition that sharpness is kept.

Description

technical field [0001] The invention relates to the technical field of diamond cutter heads, in particular to a high-life marble cutter head carcass and a manufacturing method for the cutter head. Background technique [0002] At present, there are two main types of matrix formulas for marble cutter heads. One type has only two elements, Cu and Sn. This type of matrix is ​​hard and brittle, has low wear resistance, and is sharp when cutting, but has a low service life. The other is to add Fe element on the basis of the first type of carcass. The performance of Fe is soft, and the addition of Fe can indeed improve wear resistance and increase life. However, when cutting some hard marble, the diamond is exposed slowly, and the diamond blade reduced versatility. [0003] In view of this, the inventor of this case conducted in-depth research on the above-mentioned problems, and proposed a high-life marble cutter head carcass and a manufacturing method for the cutter head, and t...
