Molding process of diamond segment

The mold loading process of diamond segment is divided into the following process requirements. This article introduces these process requirements to let everyone better understand the mold loading process of diamond segment.

1: The working layer and the non-working layer of the segment are separated: the working layer and the non-working layer of the segment must be separated and arranged. Generally, the working layer is located on the outermost side, and then the non-working and working layers are continuously extended and arranged inward. , and finally put the working layer and the non-working is located in the center part of the mold.

2: During the mold installation process of the segment, especially the high iron base segment, it is best to add a release agent: the iron powder in the high iron base segment has a strong carbon affinity, especially the high iron base segment, the iron element is too high. In many cases, the segment mold is very difficult to release, so in this case, adding a release agent can quickly help the segment to release the mold. Although the production cost of the release agent is increased, the labor cost is reduced.



3: The non-working layer of the segment is divided into iron sheet and powder layer: the non-working part of the segment is mainly the matrix part without the diamond part, while the iron sheet layer is mainly the iron powder sheet produced by the iron sheet manufacturer, which is cold pressed. In the future finished products, this product is quickly turned into iron during high temperature sintering, and is quickly consumed during the cutting process, helping the segment to remove chips during the cutting process.

4: The number of layers of the segment can be even or odd. The main structures are 1-2-1, 1-2-1-2-1, 1-2-1-2-1-2-1, of course, in special cases, 1-2-1-2-1-1- 2-1-2-1 is also possible, there are two working layers in the middle part to reduce the chip removal layer and increase the life of the segment.

5: In the process of installing the diamond segment, weight is the core factor: the weight and volume of the segment determine its density and compactness. Generally speaking, when the segment volume is constant, the segment weight is certain, then the segment Density and compactness are constant, and such a segment has an extremely uniform stability.

6: The thickness of the iron sheet of the diamond segment is extremely important, which is related to the quality of the product. The thickness of the diamond iron sheet is based on long-term experimental tests. The thickness is extremely critical. Under normal circumstances, if the thickness of the iron sheet of the segment is 1 mm, the life of the segment will increase or decrease by more than 10-30%, so many time, the thickness of the iron sheet determines the quality of the segment, so in the process of moulding the segment, it must correspond to the corresponding thickness of the iron sheet.



7: The more layers of the large diamond segment, the better the sharpness: the more layers of the segment of the inter layer big segment, the better the sharpness of the segment. During the cutting process of such segment, the discharge volume is more and the cutting edge of the segment sharpness is particularly high.

8: The working layer of the diamond segment is related to the life of the segment: the working layer of the segment is generally a little more than the non-working layer, but in terms of thickness ratio distribution, if the thickness of the non-working layer is thinner, then the working layer of the segment has a higher ratio. If it is high, the cutting life of the segment will be stronger. On the contrary, if the thickness of the working layer of the segment is insufficient, it will reflect that the cutting ability of the segment is insufficient, and the non-working layer cannot cut.this kind of segment sharpness will be good, but life must be short.

9: The tighter the bolt, the thicker the density of the segment,  of course,except the temperature aisle produces a lot of flow. In the last step of the segment moulding, the bolts must be tightened, which can help to quickly increase the density of the segment and ensure the stability of the segment.
