Abstract
The utility model discloses a plastic PC milling cutter. The plastic PC milling cutter comprises a cutter handle, wherein a cutter head is formed on the cutter handle, and consists of a dovetail groove-shaped blade connecting part, a vertical second blade part and an inverted dovetail groove-shaped first blade part, the blade connecting part is formed on the cutter handle, two ends of the second blade part are respectively connected to the blade connecting part and the first blade part, two straight tooth-shaped cutter teeth are arranged on the top end surface of the first blade part, a chip trough is formed between the two adjacent cutter teeth, and the cutter teeth penetrate through the first blade part and the second blade part. According to the plastic PC milling cutter disclosed by the utility model, the side blade of the milling cutter for plastic cutting is made to be in an inward inclined shape, so as to reduce the surface area of the chip trough, meanwhile the tooth shape is made to be an axe shape, so that the larger chip trough can be formed so as to be more conducive to the discharge of plastic chips, and the machining quality is not affected by the chips in a machining process of the milling cutter.
Description
Technical field:
The utility model relates to the technical field of milling cutter, more specifically to plastic cement PC milling cutter.
Background technology:
Milling cutter is the important cutter of one 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 in the time of 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.
Utility model content:
The purpose of this utility model 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 in the time 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 utility model comprises handle of a knife, on handle of a knife, form cutter head, cutter head is made up 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, two straight tooth-shaped cutters tooth 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.
The beneficial effects of the utility model are: its side edge by the milling cutter that carries out plastics cutting is made inside tilted shape, 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.
Brief description of the drawings:
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that enlarged drawing is looked on the right side of cutter head 2 of the present utility model.
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.
Detailed description of the invention:
See shown in Fig. 1 and Fig. 2: plastic cement PC milling cutter of the present utility model comprises handle of a knife 1, on handle of a knife 1, form cutter head 2, cutter head 2 is made up of the blade connecting portion 5 of dovetail grooved, vertical the second blade part 4 and the first blade part 3 of inverted dovetail grooved, 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, two straight tooth-shaped cutters tooth 6 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 straight tooth-shaped cutter tooth 6 of milling cutter is made axe shape by the utility model, 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 vertical milling cutter and reduced the surface area of chip trough 7 both sides.In the time of 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 utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
