Abstract

The utility model discloses a drilling and milling double-purpose cutting tool. The utility model is provided with a drilling and milling part, a milling part and a clamping part. A conical drill tip of the drilling and milling part can accurately drill holes, and can process drilling and milling circle-arc lines and various curves. The drilling and milling cutting tool can process metal materials of iron, copper, aluminum, etc., can also process nonmetal materials of timbers, plastics, rubbers, etc., can vertically or horizontally drill holes, processes circle-arc lines and various curves, has the advantages of little resistance and large cutting output, improves work efficiency, and provides a practical cutting tool for iron wood process.

Description

Brill mills double-purpose cutting tool

The utility model belongs to the processing cutlery, and particularly a kind of brill mills double-purpose cutting tool.

Drill bit is the specific purpose tool of mechanical industry, also can be used for woodwork processing, and spiral bit commonly used is symmetrical cutting edge, and when the engineered wood product slotted hole, move front and back on the planer platform, repeatedly opens brill in the two ends, hole, just can finish ream operation; When door lock is installed, need have the bigger circular hole of diameter at doorjamb, with electric hand drill in the internal drilling of lockset circumference, can only vertical drilling, can not parallelly move, need repeatedly open brill, just can finish, periphery is not slick and sly, and time-consuming, the effort of drilling operation is made troubles to timber work.

The purpose of this utility model is to overcome above technical deficiency, provides a kind of and hole, process the brill of circular arc line and various curves to mill double-purpose cutting tool.

Task of the present utility model is, bore mill double-purpose cutting tool has bore mill portion, mill portion, clamping portion, bore and mill portion's circular cone apex point and accurately pierce perforate; It two can be processed to bore and mill circular arc line and various curve; It three bores metal materials such as milling cutlery processing iron, copper, aluminium, but also nonmetallic materials such as converted timber, plastics, rubber.

Specify with embodiment below in conjunction with accompanying drawing.

Fig. 1 shows that brill mills double-purpose cutting tool double end front view.

The A portion enlarged drawing of Fig. 2 diagrammatic sketch 1.

The vertical view of Fig. 3 diagrammatic sketch 2.

Fig. 4 shows that cutlery mills portion's lead angle.

The expanded view of Fig. 5 diagrammatic sketch 4.

Fig. 6 shows that brill mills three front views of double-purpose cutting tool.

The A portion enlarged drawing of Fig. 7 diagrammatic sketch 6.

The vertical view of Fig. 8 diagrammatic sketch 7.

Among the figure, 1-bores the portion of milling; 2-mills portion; 3-clamping portion; 1-1 circular cone apex point; The horizontal cutter of 1-2; The 1-3 cutting edge; 1-4 chisel edge relief angle; 1-5 cutting edge relief angle; 2-1 mills sword; 2-2 groove rib; The 2-3 dead slot; 2-4 mills edge clearance angle; 2-5 groove rib relief angle; The 2-6 helical guide groove; The 2-7 lift angle

With reference to accompanying drawing 1-5, be two cutlery embodiment, brill mills double-purpose cutting tool to have to bore and mills portion 1, mill portion 2 and clamping portion 3, brill mills the 1 end-cone apex point 1-1 of portion and mills the cutlery longitudinal axis with brill and overlap, uniform chisel edge 1-2 that intersects with major flank and circular cone apex point 1-1 be not or not same plane, and the sword 2-1 that mills that middle part cutting edge 1-3 joins has corresponding helical guide groove 2-6.60-90 ° of the helical guide groove 2-6 lift angle of cutting edge 1-3.Brill mills portion 1 and is divided into the 2-4 sword.The chisel edge 1-2 of every sword is on same plane, and the cutting edge 1-3 of every sword is on same plane.The anterior angle of every sword chisel edge 1-2 is higher than relief angle 1-4, and cutting edge 1-3 anterior angle is higher than cutting edge relief angle 1-5, mills sword 2-1 and is higher than and mills edge clearance angle 2-4.

With reference to accompanying drawing 6-8 is three cutlery embodiment.

Bench drill or electric hand drill clamping brill are milled double-purpose cutting tool, when processing metal or nonmetallic materials boring, the circular cone apex point 1-1 of cutlery aims at drill center, starts bench drill or electric hand drill, the chisel edge 1-2 of flank, the cutting edge 1-3 that joins vertically pierce, and rounding is holed to desired depth.

Bore big hole or slotted eye, circular cone apex point 1-1 is aimed at drill center, start bench drill or electric hand drill, the chisel edge 1-2 of flank, the cutting edge 1-3 that joins vertically pierce, hole to desired depth, mill the helical guide groove 2-6 that sword 2-1 connects, cutlery is translation to the left or to the right, the anterior angle of milling sword 2-1 is milled into, from cutting edge 1-3, mill sword 2-1, helical guide groove 2-6 chip removal at any time, move in circles processing boring or slotted eye, smoothly neat, the tenon angle is clearly demarcated.

Brill mills double-purpose cutting tool, can be vertically or translation boring, and the processing circular arc line, various curves, resistance is little, and cutting output is big, increases work efficiency, for hophornbeam processing provides a kind of practical cutlery.
