Abstract
The invention discloses a PC (Poly carbonate) milling cutter for plastics. The PC milling cutter comprises a cutter handle, wherein a cutter bit is formed on the cutter handle and is composed of a dovetail-groove-shaped cutting edge connecting part, a second vertical cutting edge part and a first inverted-dovetail-groove-shaped cutting edge part; the cutting edge connecting part is formed on the cutter handle, two ends of the second cutting edge part are connected on the cutting edge connecting part and the first cutting edge part respectively, two axe-shaped straight-tooth-shaped cutter teeth are formed on the top end surface of the first cutting edge part, a chip trough is formed between the adjacent cutter teeth, and the cutter teeth run through the first cutting edge part and the second cutting edge part. According to the PC milling cutter, the side edge of the milling cutter for cutting plastics is manufactured into an inwardly inclined shape, the surface area of the chip trough is reduced, and the tooth shape is manufactured into the axe shape, so that the large chip trough is formed, plastic cuttings can be discharged conveniently, and the cuttings cannot influence the processing quality while the milling cutter works.
Description
Technical field:
The present invention relates to the technical field of milling cutter, more specifically to plastic cement PC milling cutter.
Background technology:
Milling cutter is a kind of important cutter using in modern industry machined, and present milling cutter can be divided into single head milling cutter, two blade milling cutters and common three blade milling cutters thereof etc. according to blade.And milling cutter can be processed various materials now, the side edge of the milling cutter of some straight tooth-shapeds is generally vertical-type, larger contact area between milling cutter tooth, and when some plastic products of processing, because producing friction between milling cutter operation and plastics, thereby the temperature that milling cutter is had increase, although there have cooling fluid to carry out to be cooling, but still have plastics smear metal to stick in chip trough, and these can concentrate on the chip trough of milling cutter end sword rear side with the extruding of milling cutter operation smear metal, thereby cause chip removal inconvenience, affect the crudy of product.
Summary of the invention:
Object of the present invention is exactly the deficiency for prior art, and plastic cement PC milling cutter is provided, and it can cut effective scrap fallaway groove by plastics when carrying out plastics cutting, thereby does not affect the crudy of product.
For achieving the above object, a kind of plastic cement PC milling cutter of the present invention comprises handle of a knife, on handle of a knife, form cutter head, cutter head is comprised of the blade connecting portion of dovetail grooved, vertical the second blade part and the first blade part of inverted dovetail grooved, blade connection shaping is on handle of a knife, the two ends of the second blade part are connected on blade connecting portion and the first blade part, the straight tooth-shaped cutter tooth of two axe shapes on the top end face of the first described blade part, between two adjacent cutters tooth, form chip trough, described cutter tooth runs through the first blade part and the second blade part.
As technique scheme preferably, the side edge of described cutter tooth moulding on the second blade part and the angle α of cutter head central axis are between 13.7 °～14.2 °, the angle β of blade connecting portion and handle of a knife central axis is 15 °.
As technique scheme preferably, the maximum gauge on the first described blade part equals the diameter of handle of a knife, the diameter of handle of a knife is greater than the diameter of the second blade part.
Beneficial effect of the present invention is: it makes inside tilted shape by the side edge that carries out the milling cutter of plastics cutting, from having reduced the surface area of chip trough, profile of tooth is made to axe-shape simultaneously and made to there is larger chip trough, thereby be more conducive to discharge plastics smear metal, make smear metal in milling cutter process not affect crudy.
Accompanying drawing explanation:
Below in conjunction with accompanying drawing, the present invention is described further:
Fig. 1 is structural representation of the present invention;
Fig. 2 is that enlarged drawing is looked on the right side of cutter head 2 of the present invention.
Symbol description in figure:,
1, handle of a knife; 2, cutter head; 3, the first blade part; 4, the second blade part; 5, blade connecting portion; 6, cutter tooth; 7, chip trough.
The specific embodiment:
See shown in Fig. 1 and Fig. 2: plastic cement PC milling cutter of the present invention comprises handle of a knife 1, on handle of a knife 1, form cutter head 2, cutter head 2 is by the blade connecting portion 5 of dovetail grooved, the first blade part 3 of the second vertical blade part 4 and inverted dovetail grooved forms, blade connecting portion 5 is molded on handle of a knife 1, the two ends of the second blade part 4 are connected on blade connecting portion 5 and the first blade part 3, the straight tooth-shaped cutter tooth 6 of two axe shapes on the top end face of the first described blade part 3, between two adjacent cutters tooth 6, form chip trough 7, described cutter tooth 6 runs through the first blade part 3 and the second blade part 4.
The side edge of cutter tooth 6 moulding on the second blade part 4 and the angle α of cutter head 2 central axis are between 13.7 °～14.2 °, and blade connecting portion 5 is 15 ° with the angle β of handle of a knife 1 central axis.
Maximum gauge on the first blade part 3 equals the diameter of handle of a knife 1, and the diameter of handle of a knife 1 is greater than the diameter of the second blade part 4.
Operation principle: the present invention makes axe shape by the straight tooth-shaped cutter tooth 6 of milling cutter, makes it have larger chip trough 7, is convenient to the discharge of smear metal in smear metal process; The head of milling cutter is made to inverted dovetail grooved simultaneously, compared the surface area that vertical milling cutter has reduced chip trough 7 both sides.When milling cutter cutting plastic goods, part smear metal meeting adheres on cutter head, but the smear metal of adhering in the new smear metal extruding producing of cutter head operation, but milling cutter tip rear side chip trough 7 two sides are less, the smear metal of its new generation and the smear metal of adhesion, can only be with cutter rotary rowed except working positions without attachment point.
Above content is only preferred embodiment of the present invention, for those of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, and this description should not be construed as limitation of the present invention.
