Abstract
The invention relates to a diamond blade production, which comprises laminated cold compression shaping, integrated thermal compression sintering, to avoid penetration between working layer and non-working layer; and its cutter and groove are vertical, its cutting process is reliable. And it has low cutting resistance, 40% improved efficiency and 30% improved service life.
Description
Technical field
The present invention relates to a kind of preparation method of tool made of superhard material, relate in particular to the process of diamond cutter goods.
Background technology
For the quality and the life-span of improving diamond segment, its method of manufacturing technology is more and more meticulousr.At present, what people extensively adopted is the cutter and the manufacture method of a kind of " sandwich " formula, is about to working lining and inoperative layer powder and directly pours in order and carry out hot pressing in the graphite jig.Do not have diamond in its inoperative layer, its power formulations is also simplified relatively, relative low price, this cutter head in use forms several edges of a knife and several groove, adamantine utilization rate is improved greatly, and the groove of Xing Chenging also plays guide effect simultaneously, makes sawing steady.But its shortcoming is to interpenetrate between working lining and the inoperative layer, makes that the boundary line is not clear each other, and the edge of a knife and groove are difficult to guarantee straight line, do not reach ideal effect.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of diamond knife head manufacturing technique, it can guarantee that working lining and inoperative layer do not interpenetrate, and quality and life-span improve a lot, and sawing is steady.
Technical scheme of the present invention is that a kind of diamond knife head manufacturing technique is characterized in that:
A, cutter head design is decomposed into N working lining and N-1 inoperative layer, calculates the weight of each layer respectively according to job requirement;
B, weigh out the weight of each working lining and inoperative layer powder in the balance;
C, each layer powder is respectively charged into the standard punching block, on cold press, is pressed into the square shape;
D, press edge work layer-inoperative layer-middle working lining-inoperative layer ... the order stack of edge work layer attaches together in the graphite mo(u)ld;
E, this graphite mo(u)ld is placed on hot pressed sintering on the hot press;
Cutter head is polished in f, form removal;
G, be up to the standards packing.
The invention has the beneficial effects as follows: through using proof, the edge of a knife that cutter head forms is vertical with groove standardized, and sawing process is steadily reliable, on combination saw (a dress multiple blade saw), effect is more obvious, and the sawing resistance is little, cutting-rate improves more than 40%, and improve more than 30% service life.
The specific embodiment
The present invention is the innovation to prior art, and prior art production " sandwich " cutter head is that hot pressed sintering is shaped, and the present invention then is the layering cold-press moulding, concentrates hot pressed sintering, and implementation process has only been Duoed the cooling forming operation one than prior art.As the weight of making a kind of 22 * 9 * 14mm (length * thick * height) is 5 layers of cutter head of 23 grams, and its working lining is 3 layers, and the inoperative layer is 2 layers, and 3 working linings are respectively 6.5 grams, 6 grams, 6.5 grams, and 2 inoperative layers are 2 grams.After the powder weighing that compounding is good is accurate, be respectively charged into the standard punching block of length and width fixed size, on cold press, suppress certain thickness pane, the order of--inoperative layer-middle working lining (6 gram)--inoperative layer-edge work layer (6.5 gram) is packed in the graphite again according to edge work layer (6.5 gram), send into hot press hot pressed sintering setting, form removal then, polishing, be product of the present invention after the assay was approved.
