Abstract
The utility model relates to the field of machine tool cutters, in particular to a three-blade spherical tungsten steel profile cutter. The three-blade spherical tungsten steel profile cutter comprises a cutter handle, a cutter neck and a cutter head, wherein the cutter neck is arranged between the cutter handle and the cutter head; the cutter neck is connected with the cutter head. The three-blade spherical tungsten steel profile cutter is characterized in that a conical transitional part is arranged between the cutter neck and the cutter handle; the cutter head is spherical; a circular arc abdicating groove is formed in the bottom of the cutter head; three cutting blades are arranged on the cutter head; chip discharging grooves are respectively formed below the cutting blades; a spherical surface is formed between every two chip discharging grooves; side cutter blades perpendicular to the cutting blade are arranged on the spherical surfaces. The utility model provides the three-blade spherical tungsten steel profile cutter with the advantages of suitability for processing curved surfaces of small parts, high processing precision, good chip discharging effect and long service life; according to the three-blade spherical tungsten steel profile cutter, cutters can be prevented from touching workpieces in the cutting process and the curved surfaces or circular arcs can be formed at one time.
Description
Technical field
The utility model relates to machine tool field, particularly the spherical tungsten steel forming knife of a kind of three sword.
Background technology
Aluminium alloy be take that aluminium is base the general name of alloy, the structure of the product that the aluminium alloy of take is produced as material also becomes increasingly complex, because the requirement that the variation of Al-alloy products makes it add tool setting in man-hour tool in forming and cutting is also more and more higher, the particularly processing to the little curved surface of some shape and structures or circular arc, traditional cutter tool wear aluminium when processing Al alloy parts is large, cutter life can not be guaranteed, and cannot time processing moulding, is difficult to the machining accuracy that reaches higher.
Summary of the invention
For above-mentioned technical problem, the utility model provides a kind of and can avoid cutter in working angles to encounter on workpiece, is applicable to finding Machining of Curved Surface, and machining accuracy is high, energy one-shot forming curved surface or circular arc, chip removal is effective, can cut into cut roll bits, the spherical tungsten steel forming knife of three swords of long service life.
Realize the technical solution of the utility model as follows:
The spherical tungsten steel forming knife of three swords, comprise handle of a knife, cutter neck and cutter head, cutter neck is located between handle of a knife and cutter head, cutter neck is connected with cutter head, it is characterized in that: between described cutter neck and handle of a knife, be provided with conical transition portion, cutter head is spherical, cutter head bottom is provided with circular arc avoiding hollow groove, on cutter head, be provided with three cutting edges, under cutting edge, being equipped with chip area, is spherical between chip area and chip area, and spherical is provided with the side tool sword vertical with cutting edge.
Described tool bit diameter is φ 6.3mm, and length is 6.02mm.
The tapering of described conical transition portion is 60 degree.
The overall length of described cutter neck and cutter head is 8.8mm.
The diameter of described cutter neck is φ 2.60mm.
Described overall length is 50mm, and handle of a knife diameter is φ
16mm.
Adopt such scheme, owing to being provided with conical transition portion between cutter neck and handle of a knife, the conical transition portion arranging can effectively avoid cutter in working angles to touch on workpiece, described cutter head is spherical, cutter head is provided with three cutting edges, be conducive to Machining Arc or curve form, cut energy one-shot forming, machining accuracy is high, under cutting edge, be equipped with chip area and be located at the avoiding hollow groove under cutting edge, all be conducive to the discharge of smear metal, the side tool sword vertical with cutting edge on spherical knife face, be conducive to the smear metal of rolling to cut off and get rid of, avoid smear metal long, be wound around cutter, avoid operating personnel to be injured by smear metal, avoid scorching of operating personnel's clothes, because cutter head adopts wolfram steel material, wolfram steel cutter head has good high temperature resistant and anti-wear performance, can extend the service life of cutter.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, the utility model is aforesaid will be become apparent with other object, feature and advantage.Wherein:
Fig. 1 is structural representation of the present utility model.
In figure, 1 is handle of a knife, and 2 is circular cone transition part, and 3 is cutter neck, and 4 is cutter head, 5 side tool swords, and 6 is avoiding hollow groove.
The specific embodiment
As shown in the figure: the utility model provides a kind of three sword spherical tungsten steel forming knife, comprise handle of a knife 1, cutter neck 3 and cutter head 4, cutter neck 3 is located between handle of a knife 1 and cutter head 4, cutter neck 3 is connected with cutter head 4, between described cutter neck 3 and handle of a knife 1, be provided with conical transition portion 2, conical transition portion 2 can effectively avoid the cutter in working angles to encounter on workpiece, cutter head bottom is provided with avoiding hollow groove 6, avoiding hollow groove 6 can effectively improve the chip removal ability of cutter, cutter head 4 is spherical, on cutter head 4, be provided with three cutting edges, be conducive to Machining Arc or curve form, cut energy one-shot forming, machining accuracy is high, under cutting edge, be equipped with chip area, be conducive to the chip removal in working angles, it between chip area and chip area, is spherical, spherical is provided with the side tool sword 5 vertical with cutting edge, be conducive to the smear metal of rolling to cut off and get rid of, avoid smear metal long, be wound around cutter, avoid operating personnel to be injured by smear metal, avoid scorching of operating personnel's clothes, cutter head 4 adopts wolfram steel material, wolfram steel cutter head has high temperature resistant and anti-wear performance preferably, extend the service life of cutter, described optimal way is that cutter head 4 diameters are φ 6.3mm, length is 6.02mm, the tapering of conical transition portion 2
2be 60 degree, described cutter neck 3 is 8.8mm with the overall length of cutter head 4, and the diameter of described cutter neck 3 is φ 2.60mm, described overall length is 50mm, handle of a knife diameter is φ 6mm, can obtain high accuracy like this for processing finding curved surface, and can one-shot forming when processing curve and circular arc.
The utility model is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention openly in scope, still can do some corrections or change, therefore the scope that rights protection scope of the present utility model limits with claims is as the criterion.
