Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides an embodiment:

the utility model provides an arrow tooth type tool bit, including saw bit body 1, solid fixed ring 3 and cutter head 5, mounting hole 2 has been seted up to saw bit body 1's middle department, solid fixed ring 3 has been installed through welded fastening in saw bit body 1's the outside, gu evenly seted up first bolt hole 4 on the fixed ring 3, and the quantity of first bolt hole 4 is sixteen, gu be cyclic annular evenly installed cutter head 5 on the fixed ring 3, and cutter head 5's quantity is eight, one side that cutter head 5 kept away from saw bit body 1 has all seted up dead slot 11, and dead slot 11 is the recess of irregularity form, when the staff is through watering the cooling to saw bit body 1, a plurality of dead slots 11 that cutter head 5 backs were seted up have increased cutter head 5 and cooling liquid's area, the cooling effect to saw bit body 1 has been improved.

All seted up second bolt hole 7 on cutting tool bit 5, the quantity of every group second bolt hole 7 is two, all threaded mounting has fixing bolt 6 in the second bolt hole 7, fixing bolt 6 all passes first bolt hole 4, when the terrace with edge 12 of cutting edge 9 one end damages, or after the phenomenon appears damaging in cutting tool bit 5, when the staff safeguards the tool bit, through will damaging second bolt hole 7 on cutting tool bit 5 and unscrew, can take off this cutting tool bit 5 from solid fixed ring 3, then install new cutting tool bit 5 and can accomplish the maintenance to cutting tool bit 5 in the position of this cutting tool bit 5, need not to change whole saw bit body 1, the maintenance cost is reduced.

Mounting groove 8 has all been seted up to cutting tool bit 5's inboard, and mounting groove 8's both sides all closely laminate with solid fixed ring 3, the cavity has all been seted up to cutting tool bit 5's one end, and all there is cutting edge 9 through sintering fixed mounting in the cavity, cutting tool bit 5 all is the arrow tooth type, cutting edge 9's material all is the diamond, cutting edge 9's right-hand member all sinters on cutting tool bit 5 through matrix binder 10, prismatic table 12 has all been seted up to cutting edge 9's one side, and prismatic table 12's width is 1mm, arrow tooth's cutting tool bit 5 can provide stronger cutting force, prismatic table 12 of cutting edge 9 one side cuts as main stress point, when saw bit body 1 is rotatory, prismatic table 12's both sides earlier with by the contact of cut object, the resistance when having reduced the striking, cutting efficiency has been improved.

The working principle is as follows: when cutting, arrow cusp's cutting tool bit 5 can provide stronger cutting force, the terrace with edge 12 of cutting blade 9 one side cuts as main stress point, when saw bit body 1 is rotatory, the both sides of terrace with edge 12 earlier with by the contact of cutting object, resistance when having reduced the striking, cutting efficiency has been improved, simultaneously at the in-process of cutting, when the staff is through watering the cooling to saw bit body 1, a plurality of dead slots 11 that the 5 backs of cutting tool bit were seted up have increased the area of contact of cutting tool bit 5 with cooling liquid, the cooling effect to saw bit body 1 has been improved.

And when the terrace with edge 12 of cutting edge 9 one end damaged, or behind the damage phenomenon appears in cutting tool bit 5, when the staff safeguarded the tool bit, through will damaging the second bolt hole 7 on the cutting tool bit 5 and unscrew, can take off this cutting tool bit 5 from solid fixed ring 3, then install new cutting tool bit 5 and can accomplish the maintenance to cutting tool bit 5 in the position of this cutting tool bit 5, need not to change whole saw bit body 1, the maintenance cost is reduced, the practicality of tool bit has further been promoted.
