Abstract
The invention discloses a dry-type air cooling high-alloy composite grinding and cutting tool comprising a tool body and tool bits, wherein the tool body is in a disc shape; the tool bits are arranged around the disc-shaped tool body; the tool body is made of a metal base material; the tool bits are manufactured by a WCo alloy and artificial diamond with a powder metallurgy method; the tool bits are positioned around the tool body and are distributed discontinuously; and two sides of the tool bits are both provided with chip grooves. The dry-type air cooling high-alloy composite grinding and cutting tool has the advantage of simple structure; and the tool body and the tool bits are made of special materials; and an independently designed tool bit chip groove structure and a stress elimination groove structure are adopted, and a dry-type air cooling mode is adopted for cooling the tool, thereby greatly prolonging the service life of the tool. The tool is especially suitable for grinding and cutting black metals and casting alloy materials.
Description
Technical field
The present invention relates to the technical field of cutter, more particularly relate to be used for the high alloy compound tool of grinding cutting ferrous metal and casting alloy.
Background technology
In mechanical grinding cutting industry, cutter is one of its main machining tool, at present, when the cutting ferrous metal, main method is: sawing and cut with flame by hand, its operating efficiency is all lower, and can't finish this work with common disk machinery knives, and it general mainly is made of common circular cutter cutter hub and cutter head, and cutter hub is in the form of annular discs, cutter head is positioned at around the cutter hub in the form of annular discs, cutter is when the high speed rotary work, because cutter is not designed rational chip area, like this when work, the working resistance of the cutter rotation that has strengthened has on the one hand reduced operating efficiency; Also accelerated the aging speed of cutter on the other hand, in addition, common cutter its in when work, usually use cooling fluid to do meson and remove to cool off cutter, though like this can be to the cutter cooling effect fast of getting up, its fast during cooling cutter hub and cutter head because material is inequality, two kinds of material coefficient of thermal expansion coefficients are also different, just accelerate the fatigue failure speed of cutter easily, thereby shortened the service life of cutter greatly, the material of cutter own also is not suitable for doing the grinding cutting tool at present.
Summary of the invention
Purpose of the present invention provides a kind of simple in structure in order to solve above-mentioned deficiency exactly, and long service life especially can be carried out the air-cooled high alloy composite grinding of the dry type cutting tool that grinding is cut to ferrous metal and cast alloy materials.
The technical solution that the present invention adopts in order to solve the problems of the technologies described above is as follows:
The air-cooled high alloy composite grinding of dry type cutting tool, include cutter hub and cutter head, cutter hub is in the form of annular discs, cutter head is positioned at around the cutter hub in the form of annular discs, described cutter hub adopts metal base to make, described cutter head adopts powder metallurgy method to be made by WCo alloy and diamond, and described cutter head is positioned at and is discontinuity around the cutter hub and distributes, and the both sides that are positioned at cutter head all offer chip area.
The ratio of described WCo alloy and diamond is 7: 3.
The material of described cutter head is that T65Mn, 50Mo2V, 75Cr1 and 30CrMo are wherein a kind of.
The chip area of described cutter head both sides becomes 30 ° of-90 ° of angles with the tangent line at this place of cutter head.
The chip area of described cutter head both sides is interspersed.
The thickness of described cutter hub is than the little 0.5-1 millimeter of thickness of cutter head.
Be electroplate with the corundum coating on the card of described cutter hub, this corundum coating be with cutter hub rotation contrary to involute shape pattern.
Offer stress relief groove on the described cutter hub.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is: simple in structure, adopt specific material to make cutter hub and cutter head, and adopt the cutter head chip area structure and the stress relief groove structure of independent design, adopt the air-cooled mode of dry type to cool off cutter again, prolonged the service life of cutter greatly, this cutter is specially adapted to ferrous metal and cast alloy materials are carried out the grinding cutting.

The specific embodiment
By Fig. 1; Fig. 2; Fig. 3 and shown in Figure 4; the air-cooled high alloy composite grinding of dry type cutting tool; include cutter hub 1 and cutter head 2; the material of this cutter hub 1 adopts T65Mn; 50Mo2V; 75Cr1 and 30CrMo's is wherein a kind of; this cutter head 2 adopts powder metallurgy method to be made by WCo alloy and diamond; the ratio of described WCo alloy and diamond is 7: 3; cutter hub 1 is in the form of annular discs; cutter head 2 is positioned at around the cutter hub in the form of annular discs 1; described cutter head 2 is even discontinuity distribution around being positioned at cutter hub 1; and the both sides that are positioned at cutter head 2 all offer chip area 3; this chip area 3 becomes 30 ° of-90 ° of angles with the tangent line at cutter head 2 these places; can effectively improve the chip removal effect; strong for the degree that strengthens cutter head 2 simultaneously; the chip area 3 of cutter head 2 both sides is interspersed; with the thickness of cutter hub 1 the little 0.5-1 millimeter of thickness than cutter head 2; can effectively protect cutter hub 1 is not frayed; be electroplate with corundum coating 4 on the card of described cutter hub 1; this corundum coating 4 be with cutter hub 1 rotation contrary to involute shape pattern; in order to improve the service life of cutter; on cutter hub 1, offer stress relief groove 5; this can effectively reduce the fatigue failure degree of cutter hub 1, thereby has effectively protected cutter.
Cutter major function of the present invention is characterized as carries out the air-cooled grinding cutting of mechanical dry type and abrasive machine part burr, overlap to ferrous metal, especially to cutting, its function and the economic worth highly significant of bad burr such as the foundry goods hair of car, bullet train and urban light rail train security part etc., overlap finishing polishing, dead head.
Cutter of the present invention is not to adopt cooling fluid to do meson to remove to cool off cutter, but carry out heat exchange with the cutter that compressed air is done the cutting of meson and high speed rotary grinding, and then be that cutter head and cutter hub cool off to the cutter of grinding cutting, coefficient of thermal expansion is little, has effectively prolonged the service life of cutter.
