Abstract
The invention discloses a cutter processing process, which comprises the following steps that A, the appearance of a cutter is processed by a lathe according to a drawing; B, cooling holes are processed, and two symmetrical through holes are processed in the cutter; C, straight chip discharging grooves are processed, and two straight chip discharging grooves are processed on the outer circumference of the cutter; D, high-temperature-resistant materials are fully filled in the cooling holes; E, high-frequency heating is carried out, the products are fixedly arranged on a clamp, a layer of high-frequency coil is arranged on the outer circle of the products, and the heating temperature is 300 to 450 DEG C; F, the straight chip discharging grooves are twisted into spiral grooves. The cutter processing process has the advantages that through the processing method, the processing difficulty is reduced, meanwhile, the step of forming a cooling groove in the center of the cutter is omitted, the rigid of the cutter is guaranteed, meanwhile, the depth of the chip discharging grooves is also increased, the depth of the chip discharging grooves twisted by a hot twisting process is greater than the depth of the chip discharging grooves processed by a traditional method, the chip accommodating space is greater, iron chips can be conveniently discharged out, the smoothness of inner holes and the precision of the hole diameter dimension can be perfectly guaranteed.
Description
Technical field
The present invention relates to a kind of processing technology, particularly a kind of tool sharpening technique of drilling tool.
Background technology
At present, traditional chip area processing is to utilize milling machine or special purpose machine tool to be processed into helicla flute.To cutter, carry out cooling adding man-hour requirement, Cooling Holes need be set on cutter, center cutter center Cooling Holes processing technology is in the hole of a diameter 4.3-4.5mm of middle subdrilling of cutter at present, then communicates at head two little Cooling Holes of brill and the main Cooling Holes of cutter.Such technique has a great impact chip area, and helical flute working depth is not dark, because the constraint of Cooling Holes in the middle of being subject to, center cutter, stays core to thicken, in order to guarantee that cutter has enough rigidity, so it is not the center of chip area stays core thickness to strengthen, dark thereby chip area is done.
Summary of the invention
The object of the invention is, in order to overcome the problems referred to above, provides a kind of tool sharpening technique.
For achieving the above object, the method that the present invention adopts is: a kind of tool sharpening technique, comprises the following steps;
A, according to drawing with lathe by the sharp processing of cutter out;
B, processing Cooling Holes are processed two symmetrical through holes on cutter;
C, process straight chip area, on the excircle of described cutter, process two straight chip areas;
D, in Cooling Holes, fill up exotic material;
E, high-frequency heating, be fixed on product on fixture, arranges last layer high frequency coil in product outer ring, and heating-up temperature is at 300-450 °;
F, straight type row is cut to groove be reversed into spiral groove.
As a modification of the present invention, described exotic material is one or more in carborundum, graphite, corundum.
As a modification of the present invention, described fixture comprises cutter handle of a knife retained part fixture, cutter head ejector pin clamp and intermediate holder.
The invention has the beneficial effects as follows:
The present invention is by adopting heat to turn round the processing method of technique, compare and reduced difficulty of processing with traditional diamond-making technique, reduced processing cost, saved the step of driving cooling bath at center cutter simultaneously, guaranteed the rigidity of cutter, the degree of depth intensification that also groove is cut by the row of making simultaneously, by heat, turn round the chip area that technique back-outs darker than traditional processing chip area, chip space is larger, and convenient iron filings are discharged, and well guarantees the precision of endoporus moral fineness and aperture size.

Fig. 1 is structural representation of the present invention;
Fig. 2 is A-A cutaway view of the present invention;
Fig. 3 is left view of the present invention;
Fig. 4 is A-A cutaway view of the present invention;
In figure, each parts are:
1 ejector pin clamp, 2 high frequency coils, 3 Cooling Holes, 4 clamping fixtures, 5 cutter bodies, 6 intermediate holder.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated;
Below in conjunction with embodiment and with reference to accompanying drawing, the invention will be further described, should understand the following specific embodiment and only for the present invention is described, is not used in and limits the scope of the invention.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in width figure, and word " interior " and " outward " refer to respectively the direction towards or away from specific features geometric center.
Embodiment 1:
A cutter, this cutter is hard alloy rotatable shallow hole drilling, is a kind of aperture knife tool, is mainly used in solid material boring.Be applicable to the equipment such as Digit Control Machine Tool, machining center, engine lathe, boring machine, drilling machine, its processing method comprises the following steps;
A, according to drawing with lathe by the sharp processing of cutter out, as the cutter of Φ 30mm, main diameter is Φ 29mm
B, processing Cooling Holes 3 are processed two symmetrical through holes on cutter, and the diameter of two through holes is Φ 2mm, and aperture axle core is 9mm apart from cutter body 5 axle core distances.
C, process straight chip area, on the excircle of described cutter, by milling machine, mill out two straight chip areas, the length of chip area is 95mm, and width is 10mm, and the degree of depth is 4.5mm.
D, in Cooling Holes, fill up the exotic material of fine granularity, exotic material is one or more in carborundum, graphite, corundum.
E, high-frequency heating, be fixed on product on fixture, and described fixture comprises the clamping fixture 4 of cutter shank portion, the ejector pin clamp 1 of cutter head and intermediate holder 6.In product outer ring, arrange last layer high frequency coil 2, give high frequency coil 2 energisings, heating-up temperature is at 300-450 °.
F, straight type row is cut to groove be reversed into spiral groove, by the good direct chip discharging groove of leading milling, utilize the fixture of holding cutter shank that one group of change gear is installed after fixture, change gear links with four axle horizontal boring and milling machine workbench again, thereby realize, direct chip discharging groove is twisted into helicla flute.Intermediate holder 6 is by the hemispherical bootstrap block of upper and lower two pairings, and in heating distortion, bootstrap block moves from left to right, thereby makes to form smooth helical flute in the middle of cutter.
The present invention is by adopting heat to turn round the processing method of technique, compare and reduced difficulty of processing with traditional diamond-making technique, reduced processing cost, saved the step of driving cooling bath at center cutter simultaneously, guaranteed the rigidity of cutter, the degree of depth intensification that also groove is cut by the row of making simultaneously, by heat, turn round the chip area that technique back-outs darker than traditional processing chip area, chip space is larger, and convenient iron filings are discharged, and well guarantees the precision of endoporus moral fineness and aperture size.
The above, be only preferred embodiment of the present invention, is not the present invention to be done to the restriction of any other form, and according to any modification or equivalent variations that technical spirit of the present invention is done, still belongs to the present invention's scope required for protection.
