Description
Technical field
A kind of fluted drill is the utility model is related to, refers in particular to process a kind of processing stainless steel fluted drill, belongs to cutting element
Technical field.
Background technology
Fluted drill is to be relatively fixed the rotary cutting of axis by it with the instrument of the circular hole of drilling workpiece.Because of its chip pocket
Curl and be similar to fried dough twist and gain the name.Helicla flute has 2 grooves, 3 grooves or more groove, but most commonly seen with 2 grooves.Fluted drill can be pressed from both sides
Hold to hold in hand fluted drill manually, electrically and used on formula boring bar tool or drilling machine, milling machine, lathe or even machining center.Drill bit material
Material is generally high-speed tool steel or hard alloy.
But existing fluted drill processing stainless steel hardness is inadequate, and stainless steel belongs to difficult-to-machine material, existing fluted drill
Processing stainless steel by produce processing hardening and glutinous knife perplex normal process, it is impossible to meet its requirement for existing cutter.
Utility model content
The purpose of the utility model is to provide a kind of processing stainless steel fluted drill for overcome the deficiencies in the prior art, gram
Chip removal is difficult when having taken processing stainless steel and processing hardening causes the problems such as cutter rupture, can smoothly drill out institute on stainless steel
The hole needed, without beating internal point, production efficiency is greatly improved, has saved cost.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of processing stainless steel fluted drill, including
Drillstock, drill lip, transiting rod and chip area, one end of transiting rod are connected with drillstock, and the other end of transiting rod is connected with drill lip.
Chip area is twist arranged on the outer wall of drill lip, and the length L2 of drill lip is 5.0 ± 0.02mm, the end of drill lip
Drill bit is provided with, all sword margin width L3 of described drill bit are 0.13mm, and the unilateral wide L4 of cutter hub is 0.72mm after drill bit is slotted, and is bored
The apex point included angle A 1 of crown end two is 140o, and the helical angle A2 of chip area is 30o, and drillstock, drill bit and transiting rod use integral type knot
Structure forms cutter hub.
As the further optimization of the technical program, the length of the cutter hub described in the utility model processing stainless steel fluted drill
Degree L1 is 38 ± 0.2mm.
As the further optimization of the technical program, the material of the cutter hub described in the utility model processing stainless steel fluted drill
Material uses tungsten-cobalt series hard alloy.
As the further optimization of the technical program, drillstock described in the utility model processing stainless steel fluted drill it is straight
Footpath D1 is 3 0-0.005mm;The diameter D2 of drill lip is 1.3-0.005-0.015mm.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
The processing stainless steel fluted drill of the utility model, chip removal is difficult when overcoming processing stainless steel and processing is hard
Change causes the problems such as cutter rupture, can smoothly drill out required hole on stainless steel, without beating internal point, increase substantially
Production efficiency, has saved cost.
Brief description of the drawings
Technical solutions of the utility model are described further below in conjunction with the accompanying drawings：
Accompanying drawing 1 is the front view of the utility model processing stainless steel fluted drill.
Accompanying drawing 2 is the left view of the utility model processing stainless steel fluted drill.
Wherein：Drillstock 1, drill lip 2, transiting rod 3, chip area 4, drill bit 5.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
A kind of processing stainless steel fluted drill described in the utility model as shown in figure 1 and 2, including：Drillstock 1, bore
Sword 2, transiting rod 3 and chip area 4, one end of transiting rod 3 are connected with drillstock 1, and the other end of transiting rod 3 is connected with drill lip 2, transition
Bar 3 is tapered.
Chip area 4 is twist arranged on the outer wall of drill lip 2, and the length L2 of drill lip 2 is 5.0 ± 0.02mm, drill lip 2
End set has drill bit 5, and all sword margin width L3 of described drill bit 5 are 0.13mm, and the unilateral wide L4 of cutter hub is after drill bit 5 is slotted
0.72mm, the apex point included angle A 1 of 5 top of drill bit two are 140o, and the helical angle A2 of chip area 4 is 30o, drillstock 1, drill bit 2 and transiting rod
3 form cutter hub using integral structure.
The length L1 of described cutter hub is 38 ± 0.2mm.
The material of described cutter hub uses tungsten-cobalt series hard alloy.
The diameter D1 of described drillstock 1 is 3 0-0.005mm;The diameter D2 of drill lip 2 be 1.3-0.005-
0.015mm。
Drillstock 1, drill bit 5 and transiting rod 3 form cutter hub using integral structure, and each parameter that whole cutter hub uses is using tree
Fat diamond wheel grinding is reached, and the cutter hub surface roughness formed using resin diamond grinding wheel grinding is small, is favorably improved
The quality to be drilled, the material of cutter hub use the hardness HRA of tungsten-cobalt series hard alloy as 93 or so, more than the hardness of stainless steel,
And tungsten-cobalt series hard alloy has high hardness, wear-resisting, intensity and a series of premium properties such as toughness is preferable, heat-resisting, corrosion-resistant,
Particularly its high rigidity and wearability, is also held essentially constant at a temperature of 500 DEG C, still has at 1000 DEG C very high
Hardness, in processing stainless steel, caused cutting will discharge along chip area 4, and the high resistant to elevated temperatures cutter hub of hardness will not produce
The phenomenon of hardening is processed, can smoothly drill out required hole on stainless steel, while the unilateral wide L4 of cutter hub is after the fluting of drill bit 5
0.72mm, the 0.72mm width of drill bit 5 are big, and intensity is high, will not damage drill bit 5 during processing, while the drill bit 5 of high rigidity can one
Secondary property drilling forming, the drill bit without high rigidity, which is felt relieved, to punch, and production efficiency is greatly improved, has saved cost, has bored simultaneously
The diameter D1 of handle 1 is 3 0-0.005mm;The diameter D2 of drill lip 2 is 1.3-0.005-0.015mm, the drillstock 1 of small diameter
Less carry out reaming can be entered with drill lip 2, expands the use range of processing stainless steel fluted drill.
It the above is only concrete application example of the present utility model, do not form any limit to the scope of protection of the utility model
System.All technical schemes formed using equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it
It is interior.
