Detailed description of the invention
Please refer to Fig. 1, the utility model preferably embodiment provides a kind of cutter 100.Cutter 100 comprises cutter hub 10, handle of a knife 20 and cutting portion 30.
Cutter hub 10 is roughly in column, and its cross section is circular.Cutter hub 10 has central axis a.When cutter 100 carries out machining, with the central axis a of cutter hub 10 for rotating shaft rotates.Cutter hub 10 comprises front end 11 and rear end 12.Be understandable that, the cross section of cutter hub 10 also can be rectangle, triangle or other is polygon-shaped.
Handle of a knife 20 is formed on the rear end 12 of cutter hub 10, and it can be staight shank form, also can be taper shank form, for cutter 100 being connected to the main shaft of Digit Control Machine Tool (not shown), to keep adding the stability of cutter 100 in man-hour.
Cutting portion 30 is formed on the front end 11 of cutter hub 10, comprises main cutting portion 31 and secondary cutting portion 32.Main cutting portion 31 and secondary cutting portion 32 have common central axis a with cutter hub 10.Main cutting portion 31 is disposed adjacent on the central axis a direction of cutter hub 10 with secondary cutting portion 32, and main cutting portion 31 is positioned at the end of whole cutter 100.In addition, the cross-sectional area in main cutting portion 31 is less than the cross-sectional area of secondary cutting portion 32.Main cutting portion 31 is for carrying out machining to the cutting position of product (not shown), and secondary cutting portion 32 is for excising the burr produced along cutting direction in the edge at the cutting position of product.
Please refer to Fig. 2, main cutting portion 31 comprises the first cutting edge 311, second cutting edge 312 and the 3rd cutting edge 313.Be understandable that, the quantity of the cutting edge that main cutting portion 31 comprises also can be set to any number of according to Production requirement.In the present embodiment, in the direction of rotation of cutter 100, namely, in Fig. 2 on the direction shown in arrow, the first cutting edge 311, second cutting edge 312 and the 3rd cutting edge 313 circumferentially interval are arranged, and the first cutting edge 311, second cutting edge 312 and the 3rd cutting edge 313 are straight tooth shape formula.The clearance surface 3113 that first cutting edge 311 comprises the rake face 3111 being formed at its side, the rear knife face 3112 being formed at its other side and is connected at an angle with rake face 3111.The structure of the second cutting edge 312 and the 3rd cutting edge 313 is identical with the structure of the first cutting edge 311.
Please refer to Fig. 3, rake face 3111 is obliquely installed with central axis a is angled.Rear knife face 3112 comprises major first flank 3114, the arrange with major first flank 3114 one-tenth obtuse angle second rear knife face 3115 and the 3rd rear knife face 3116 arranged with knife face 3115 one-tenth obtuse angle after second.Be understandable that, the quantity of rear knife face 3112 also can be any number of.Clearance surface 3113 for derive when cutter 100 works produce chip, clearance surface 3113 by cutting portion 30 away from the oblique outer surface extending secondary cutting portion 32 of end face 33 of handle of a knife 20.
First cutting edge 311 offers breach 3117 on the direction being parallel to cutter 100 radial direction.Breach 3117 equals the product degree of depth to be processed apart from the vertical range of the end face 33 in main cutting portion 31; utilize the first cutting edge 311 by the feeding of product side with this; man-hour is added to product; breach 3117 is formed and dodges position; the diaphragm (not shown) of product surface is just contained in breach 3117, and the first cutting edge 311 can not be cut to diaphragm.Meanwhile, because the first cutting edge 311 rotates around central axis a, the revolving force of the first cutting edge 311 can tear diaphragm, thus diaphragm and product section are departed from.
After completing machining to multiple product, utilize air pressure gun can blow off disposable for the diaphragm of the plurality of product surface, high-effective and labour-saving.
Secondary cutting portion 32 comprises the first blade 321, second blade 322 and the 3rd blade 323.Be understandable that, the quantity of the corresponding cutting edge included by main cutting portion 31 of quantity of the cutting edge portion that secondary cutting portion 32 comprises is arranged, and can be any number of.First blade 321 and the coplanar setting of the first cutting edge 311, the secondary clearance surface 3213 comprising the lip surface 3211 being formed at its side, the rear edge face 3212 being formed at its opposite side and be connected with lip surface 3211.Lip surface 3211 is extended to form by rake face 3111.Extended to form to the external peripheral surface of cutter hub 10 by rear knife face 3112 one end away from end face 33.Rear edge face 3212 comprises the first rear edge face 3214, the second rear edge face 3215 arranged with the first obtuse angle, 3214 one-tenth, rear edge face and the 3rd rear edge face 3216 arranged with the second obtuse angle, 3215 one-tenth, rear edge face.Be understandable that, the quantity in rear edge face 3212 also can be any number of.After the angle of the first rear edge face 3214 and major first flank 3114, the second rear edge face 3215 and second, the angle of the angle of knife face 3115, the 3rd rear edge face 3216 and the 3rd knife face 3116 is afterwards obtuse angle.Secondary clearance surface 3213 is extended to form by the external peripheral surface of clearance surface 3113 to cutter hub 10, and the scrap produced product cutting processing is exported to the outside of cutter 100 through secondary clearance surface 3213 by clearance surface 3113.The structure of the second blade 322 and the 3rd blade 323 is identical with the structure of the first blade 321.
Cutter 100 can select suitable material to make according to its purposes.Generally, preferred material is intensity and toughness carbide alloy and high-speed steel all preferably.In addition, also by forming various dura mater to improve the cutting ability of cutter 100 on the surface of the first cutting edge 311, second cutting edge 312 and the 3rd cutting edge 313.The dura maters such as titanium carbide (TiC), TiAlN (AlTiN), TiAlN (TiAlN) or TiCN (TiCN) can be adopted according to the purposes of cutter 100.
Understandably, secondary cutting portion 32 also can not arrange cutting edge, only uses as the connecting portion connecting cutter hub 10 and main cutting portion 31.
Above-mentioned cutter 100 comprises main cutting portion 31 and secondary cutting portion 32, and main cutting portion 31 is for cutting product position to be processed.Main cutting portion 31 comprises the multiple cutting edges 311 arranged at equal intervals along cutter 100 circumference; the plurality of cutting edge 311 all offers breach 3117; breach 3117 equals the product degree of depth to be processed apart from the distance of the end face 33 in main cutting portion 31; utilize cutting edge 311 by the feeding of product side; product is processed; breach 3117 is formed and dodges position, and the diaphragm of product surface is just contained in breach 3117, and the first cutting edge 311 can not be cut to diaphragm.Simultaneously; because the first cutting edge 311 rotates around central axis a; the revolving force of the first cutting edge 311 can tear diaphragm; thus make diaphragm in the process of processing product; can depart from from product upper part; after machining is completed to multiple product, utilize air pressure gun can blow off disposable for the diaphragm of the plurality of product surface, can effectively improve striping efficiency.
Be appreciated that those skilled in the art also can do other changes in the utility model spirit, as long as it does not depart from technique effect of the present utility model.These changes done according to the utility model spirit, are included within the utility model scope required for protection.
