Abstract
A W-shaped cutter for processing a graphite boat is composed of a knife blade, a knife handle and a connecting part, wherein the blade and the connecting part are formed into an integrated structure through the knife handle. The blade is composed of a rectangle cutting edge and W-shaped cutting edges, wherein two sides of the rectangle cutting edge protrude outward, the W-shaped cutting edges are in the middle of the knife blade, and a pluralitiy of groups of the W-shaped cutting edges are arranged on the knife blade. The W-shaped cutter for processing the graphite boat has the advantages of being simple in structure, low in cost, and capable of completing processing of the graphite boat, avoiding the phenomenon of crack or break of the graphite boat, improving production efficiency of an enterprise and effectively reducing operation cost of the enterprise.
Description
Technical field
The utility model relates to a kind of production auxiliary of W shape graphite boat, specifically a kind of cemented carbide sintering W shape graphite boat tool.
Background technology
Carbide alloy is a kind of alloy material of being made by powder metallurgical technique by the hard compounds of refractory metal and binding metal.Have that hardness is high, wear-resisting, intensity and a series of premium properties, particularly its high rigidity and wearability such as toughness is better, heat-resisting, corrosion-resistant, even also substantially remain unchanged, still have very high hardness in the time of 1000 ℃ at the temperature of 500 ℃.Therefore, carbide alloy is widely used in cutter material, as lathe tool, milling cutter, planing tool, drill bit, boring cutter etc.
Need to use graphite boat in the production process of hart metal product, it plays carrying and supports in the sintering process of carbide alloy effect.Graphite boat is comprised of the groove of a series of W shapes, if or adopt the plain-milling machine machining center to process, there are waste man-hour and the low problem of product percent of pass, so just cause the raising of enterprise's production cost.In addition, although graphite is a kind of nonmetallic materials that can cut, the fragile material that it belongs to inhomogeneous structure has the characteristics such as structural inhomogeneity and porous, and phenomenon therefore easily cracks or fracture in the process of reciprocating.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of W shape graphite boat tool, it is simple in structure, can once complete the processing of W shape graphite boat, avoids graphite boat to crack or the phenomenon that fractures, enhance productivity, and then can effectively reduce the production cost of enterprise.
The utility model is the deficiency that solves the problems of the technologies described above, the technical scheme that adopts is: W shape graphite boat tool, formed by blade, handle of a knife and connector, blade is integrally formed structure by handle of a knife and connector, described blade is comprised of to the rectangle cutting edge of outer projection and the W shape cutting edge at middle part both sides, and W shape cutting edge is provided with many groups.
The utility model, the overall width of described blade are 100-450mm.
The utility model, the W shape cutting edge in the middle part of described blade is provided with 5-10 groups.
The utility model, in described W shape cutting edge, the angle of each tooth is 90 °-120 °.
The beneficial effects of the utility model are: W shape graphite boat tool of the present utility model, and simple in structure, cost is low, can once complete the processing of graphite boat, avoid graphite boat to crack or the phenomenon that fractures, improved enterprises production efficiency, can effectively reduce the operating cost of enterprise.

Fig. 3 is the structural representation of W shape graphite boat.
Reference numeral: 1, blade, 2, handle of a knife, 3, connector.
The specific embodiment
As shown in the figure, W shape graphite boat tool, formed by blade 1, handle of a knife 2 and connector 3, blade 1 is integrally formed structure by handle of a knife 2 and connector 3, described blade 1 is inverted U-shaped, is comprised of to the rectangle cutting edge of outer projection and the W shape cutting edge at middle part both sides, and W shape cutting edge is arranged on the recess of blade 1, W shape cutting edge is provided with many groups, and 5-10 groups can be set.As shown in Figure 1, in described W shape cutting edge, the best angle of each tooth is 90 °-120 °, and the angular range that is α is: 90 °-120 °, the overall width scope of cutter is: 100-450mm, whole cutter are the structures of one.The connector 3 of cutter is fixed on plain-milling machine, the graphite boat raw material are fixed on the milling machine processing platform, adjust raw-material position, the running of milling machine spindle and the reciprocating motion of processing platform, one completes the processing of graphite boat (shown in Figure 3), take off the graphite boat that has machined, so repeat above-mentioned operation.
