Abstract
The utility model relates to a cutter structure which is composed of a cutter body, a cutter head, a hard alloy composite sheet or a polycrystalline diamond composite sheet and a cubic boron nitride composite sheet, wherein a groove is arranged on the cutter head, an included angle of 60 DEG-80 DEG is formed from the bottom surface of the groove and a straight wall, and one surface of the hard alloy composite sheet or the polycrystalline diamond composite sheet and the cubic boron nitride composite sheet have an included angle of 60 DEG-80 DEG. The utility model has the advantage of simple structure, and can bear impact which is generated by the cutting force of a cutter point and decompose the intense impact of weld; the intense impact is generated by the cutting force; the hard alloy composite sheet or the polycrystalline diamond composite sheet and the cubic boron nitride composite sheet are not easy to unsolder to drop from the cutter body, so the life of the cutter is prolonged.
Description
Technical field
The utility model relates to a kind of cutter structure.Belong to the machine tools field.
Background technology
The circular saw serrated knife uses in machined in a large number, its structure as shown in Figure 2, on cutter head 2, leave groove, carbide alloy or composite polycrystal-diamond, cubic boron nitride composite sheet are inlayed into above-mentioned groove and welded, make carbide alloy or composite polycrystal-diamond, cubic boron nitride composite sheet and cutter hub become one.Traditional structure as shown in Figure 2, the bottom surface of groove forms 90 degree angles with straight wall, the one side of carbide alloy or composite polycrystal-diamond, cubic boron nitride composite sheet also is 90 degree angles, coupling is set in the groove of 90 degree angles soldered.Add man-hour at the cutter that uses structure like this, the point of a knife of carbide alloy or composite polycrystal-diamond, cubic boron nitride composite sheet is subjected to cutting force and impacts, carbide alloy or composite polycrystal-diamond, cubic boron nitride composite sheet easily from the cutter hub sealing-off fall down.Cause cutter to scrap.
The utility model content
The purpose of this utility model is to improve the shortcoming of existing circular saw serrated knife structure and provides a kind of circular saw serrated knife to sign an undertaking.Can solve the sealing-off problem.
For achieving the above object, the utility model is taked following design: cutter structure is made up of cutter hub, cutter head and carbide alloy or composite polycrystal-diamond, cubic boron nitride composite sheet, leave groove on the cutter head, the bottom surface of groove forms 60-80 degree angle with straight wall, and the one side of carbide alloy or composite polycrystal-diamond, cubic boron nitride composite sheet also is a 60-80 degree angle.
The utility model is simple in structure, leave groove on the cutter head, the one side of groove leaves 60-80 degree angle, the one side of corresponding carbide alloy or composite polycrystal-diamond, cubic boron nitride composite sheet also is a 60-80 degree angle, coupling welds together mutually, and the cutting force that can bear from point of a knife impacts, and decomposes the impact of cutting force to weld strength, be not easy that sealing-off falls down from the cutter hub, prolonged the life-span of cutter.
