Description
Technical field
The utility model relates to aluminium alloy manufacture field, particularly relates to a kind of grooving cutter.
Background technology
Aluminium alloy, to add man-hour requirement cutting edge roundness sharp especially, could reduce friction and eliminate sticky cutter phenomenon.Present grooving cutter, adds contact area between man-hour and workpiece comparatively large, so cutting edge is sharp not, friction is comparatively large, and sticky cutter phenomenon is more serious; Simultaneously because aluminum alloy materials is softer, chip is not easy fracture, adds chip in man-hour and is easily entangled on cutter and affects machined surface quality and precision, scratch the alloy product processed, even forge a knife, cause percent defective to uprise at grooving.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of grooving cutter, and chip breaking is more prone to, and effectively eliminates sticky cutter phenomenon.
For solving the problems of the technologies described above, the utility model takes following technical scheme:
A kind of grooving cutter, comprise knife bar and the cutter head being arranged on knife bar one end, cutter head edge is arc-shaped, cutter head comprises front end blade part and chip breaking portion, rear end, front end blade part is provided with some blades, and chip breaking portion, rear end is provided with some L-type chip breaking swords, and center, chip breaking portion, rear end is provided with chip removal mouth.Aluminium alloy adds the larger volume chip produced man-hour, slides to L-type chip breaking sword, slides to chip removal mouth after being cut off by chip breaking sword two swords, and the chip centralized pool fallen earthward under gravity, certainly for increasing chip removal effect, chip removal mouth can connect vacuum pipe, carries out chip removal under vacuum.
Further, front end blade part is provided with some sword grooves and fixing hole, and sword groove is arranged on front end blade part arc surface, and blade is provided with the fastener hole corresponding with described fixing hole, blade inserts sword groove, and run through fixing hole by screw, blade is fixed on the blade part of front end by fastener hole.The utility model adopts sword groove to install blade, but not blade and cutter head are made of one structure, and one is consider that different aluminum alloys operation needs the cutter of different model, adopts sword groove to be convenient to change blade; Even if two is that blade is damaged in operation process, also only can change blade, if adopt integral structure, cutter head and blade all need to change, and will waste resource very much like this.
Further, sword groove upper surface connects with front end blade part upper surface, described sword groove upper and lower surperficial place plane is all horizontal by 18 degree of angles, blade is made to have larger anterior angle after insertion sword groove, front end blade part and chip breaking portion, rear end upper surface are 10 degree of angles simultaneously, blade has larger relief angle man-hour adding, can ensure that blade chip cutting edge is sharp like this, reduce and add the friction of man-hour and workpiece, front end blade part and chip breaking portion, rear end upper surface be that 10 degree angles are also convenient to the chip that blade cuts generation and are slided to chip breaking portion, rear end in addition.
Further, the number of sword groove is three, be respectively the front cutting edge of cutter head, left blade and right blade, the vertical plane of the right surperficial place plane of described left blade and right blade place sword groove from front to back horizontal by 5 degree of angles, make front cutting edge forward feed time, avoid the friction of left blade and right blade and workpiece, during left and right directions feed, under the effect of axial cutting force, knife bar produces about 2 degree of deflections, thus avoids the friction of front cutting edge and workpiece.
Further, the number of L-type chip breaking sword is seven, and is evenly arranged in chip breaking portion, rear end along cutter head outer arc, and L-type chip breaking sword is provided with screw hole, and chip breaking portion, described rear end correspondence is provided with fastener hole.L-type chip breaking blade tip end is all towards cutter head outer arc, and L-type chip breaking sword two sword length are identical, and its length is 5-7cm, and seven L-type chip breaking swords distance is between any two 2-4cm.
Beneficial effect: (1) the utility model is by arranging L-type chip breaking sword structure, chip breaking sword cuts the chip that aluminium alloy processing produces, there is good chip breaking effect, effectively can avoid the impact adding larger volume chip in man-hour, such as aluminum strip is to the winding of cutter head, and for increasing chip removal effect, chip removal mouth connects vacuum pipe, carries out chip removal under vacuum.(2) the utility model blade is provided with larger anterior angle and relief angle, can ensure that blade chip cutting edge is sharp, reduces the friction adding man-hour and workpiece.
Accompanying drawing explanation

Fig. 2 is the utility model sword groove structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of grooving cutter that the utility model provides, comprise knife bar 1 and the cutter head 2 being arranged on knife bar 1 one end, described cutter head 2 edge is arc-shaped, described cutter head 2 comprises front end blade part 3 and chip breaking portion, rear end 4, described front end blade part 3 is provided with some blades, and chip breaking portion, described rear end 4 is provided with L-type chip breaking sword 5, and center, chip breaking portion 4, described rear end is provided with chip removal mouth 7.
Front end blade part 3 is provided with some sword grooves 12 and fixing hole 8, described sword groove 12 is arranged on front end blade part 3 arc surface, described blade is provided with the fastener hole corresponding with described fixing hole 8, described blade inserts sword groove 12, and run through fixing hole 8 by screw, blade is fixed on front end blade part 3 by fastener hole.
