Abstract
The utility model relates to a hard alloy sheet dowelling jig, which comprises a cutter body, wherein a blade is arranged on the cutter body; and the cutter body is provided with a chip accommodating groove. The hard alloy sheet dowelling jig is characterized in that: a stepped positioning twist drill is arranged on the cutter body; and the bottom of the chip accommodating groove is provided with an oblique plane which forms an angle of 10-50 degrees with the central axis of the cutter body. The stepped positioning twist drill is fixed on the cutter body through a compression screw. The hard alloy sheet dowelling jig has a simple structure, high chip discharging performance and high processing accuracy; and the use safety of a cutter is enhanced, the use performance of a drill bit is enhanced, and the service life of the drill bit is prolonged.
Description
Technical field
The utility model relates to a kind of carbide alloy thin plate hole drill of suitable machining thick plates material.
Background technology
General carbide alloy thin plate hole drill is the iron filings that adopt chip pocket form processing cutting to get off in the existing market, and adopts no step location fluted drill.This way has several shortcomings: 1, the form of smear metal is very important, and the variation of processing dimension error, cutting material, smear metal abnormal deformation etc. all possibly cause chip space not enough, makes cutter not reach the maximum cutting-in of design; 2, in the location fluted drill drill moment the cutter blade with the often uncontrollable impact of appearance of surface of the work, cause the tipping and the fracture of blade.
Summary of the invention
The utility model technical problem to be solved is that to solve drill chuck clamping speed slow and need the technical problem of instrument, and a kind of carbide alloy thin plate hole drill is provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this carbide alloy thin plate hole drill; Comprise cutter hub; Blade is installed on the cutter hub; Cutter hub is provided with chip pocket, it is characterized in that being equipped with on the cutter hub step location fluted drill, and the chip pocket bottom has the inclined-plane that becomes 10～50 degree with the cutter hub central axis.
The utility model step location fluted drill is fixed on the cutter hub through housing screw.
The utility model is simple for structure, and through employing chip pocket bottom faces and cutter hub central shaft tape certain angle inclined-plane, and the inclined-plane is outside; Make chip pocket that certain chip removal performance arranged; Increased chip space virtually, a large amount of cutting heats are taken away in smear metal, have reduced the cutting heat of cutter and workpiece; Reduced of the influence of heat expansion effect, improved machining accuracy processing; Cutting force reduces when adopting the step fluted drill to make the centre drill location, locatees more convenient; After the head step drills, rear end step cutting edge is the reaming drilling,, cutting resistance is littler, has reduced centre drill and has drilled moment cutter blade and the impact possibility of workpiece, has improved the safety in utilization of cutter, and has improved drill bit serviceability and service life.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the A-A cutaway view of Fig. 2.
The specific embodiment
Referring to Fig. 1～Fig. 3; The utility model embodiment comprises cutter hub 1, blade 2, step location fluted drill 4, takes off material spring 5 and housing screw 6; Cutter hub 1 is provided with chip pocket 3 and several blades 2; Chip pocket 3 bottoms have the inclined-plane that becomes 10～50 degree with cutter hub 1 central axis, and step location fluted drill 4 is installed on the cutter hub 1 through housing screw 6, take off material spring 5 and are sleeved on the fluted drill 4 of step location.
Chip pocket 3 through band chip removal effect makes the chip space of cutter obtain bigger guarantee, and heat dispersion is better, adopts step location fluted drill 4, reduces the uncontrollable impact in the cutter use, improves drill bit serviceability and service life, improves machining accuracy.
The simple deformation or the combination of every the utility model embodiment technical scheme and technical characterictic all should be thought the protection domain that falls into the utility model.
