Abstract
A cutter for PC (polycarbonate)/PMMA (polymethyl methacrylate) production and processing comprises a cutter body; a cutting head is arranged on one side of the cutter body; blades are formed in the bottom end of the cutting head and comprise a slanting edge and a cutting edge; the slanting edge and the cutting edge tilt and approach to each other; the inclined angle between the slanting edge and the vertical direction is 4 degrees; the length proportion between the slanting edge and the cutting edge is 5 to 3.5; the cutting head is narrower than the cutter body; two sides of the cutting head become narrower and narrower from the lower end of the cutter body to the middle of the cutting head symmetrically, so that the cutting head is formed. The cutter has the advantages that the structure is simple; the use is convenient; the service life is long; the fracture period of the cutting head is long; the cutter replacement frequency is low; the production efficiency is improved.
Description
Technical field
The utility model relates to PC/PMMA production and processing cutter, and it is the cutter that a kind of edge strength is large, be difficult for breaking, belongs to cutter field.
Background technology
PC is the abbreviation of Merlon, and it is the macromolecular compound that contains carbonic ester structure in molecule chain and take its general name as the various materials that make of basis.By being with ester group difference can be divided into several large classes such as aliphatic, alicyclic, aromatic series and fat-aromatic series in molecular structure.And take bisphenol A-type polycarbonate as most important, molecular weight is generally 3-10 ten thousand.In without special instruction situation, usually said polycarbonate all refers to bisphenol A polycarbonate and modification kind thereof.Due to its good mechanical performance, be commonly called as shellproof glue.
PMMA is the abbreviation of polymethyl methacrylate, is commonly called as lucite, is that to synthesize up to now in transparent material quality the most excellent, and price is more suitable kind again.
After PC and PMMA production and processing moulding, need to cut with cutter, traditional cutter, when cutting, keeps same rotating speed conventionally, until cutter cutting surfaces does not reach requirement, changes cutter, causes the utilization rate of cutter not high, and the life-span is short.Cutter tool cutting edge angle is generally 75 °, and radial cutting force is excessive, and point of a knife is stressed to be concentrated, easily disconnected; Meanwhile, cutter side edge and cutting edge length ratio 2:5, tool diameter is less, after cutter is stressed, also easily produces fracture, causes cutter life very short, changes frequent.
Summary of the invention
In order to solve the problem of above-mentioned existence, the utility model discloses a kind of PC/PMMA production and processing cutter, this cutter life is long, and cutter head cloth easily ruptures.
PC/PMMA production and processing cutter, comprises cutter hub, and a side of cutter hub is cutter head, cutter head bottom is blade, blade comprises oblique sword and the cutting edge that mutual inclination is close, and tiltedly the angle of inclination of sword and vertical direction is 4 °, and tiltedly the length ratio of sword and cutting edge is 5:3.5.
The width of described cutter head is less than cutter hub width, and cutter head tilts symmetrical towards middle gradual change formation from cutter hub lower end.
The width of described cutter head is 1/2 ~ 2/3 of cutter hub width.
The utility model, simple in structure, easy to use, long service life, the cycle of cutter head fracture is long, and more the frequency of tool changing is low, enhances productivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Reference numerals list: 1-cutter hub, 2-cutter head, 3-oblique sword, 4-cutting edge.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.Should understand the following specific embodiment and only for the utility model is described, be not used in restriction scope of the present utility model.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, and word " interior " and " outward " refer to respectively the direction towards or away from specific features geometric center.
Visible by reference to the accompanying drawings, this PC/PMMA production and processing cutter, comprise cutter hub 1, one side of cutter hub 1 is cutter head 2, cutter head 2 bottoms are blade, blade comprises oblique sword 3 and the cutting edge 4 that mutual inclination is close, and tiltedly sword 3 is 4 ° with the angle of inclination of vertical direction, and tiltedly sword 3 is 5:3.5 with the length ratio of cutting edge 4.The utility model, oblique sword 3 and cutting edge 4 are crossed swords and are formed sharp point of a knife, point of a knife cutting PC/PMMA, tiltedly sword 3 is 4 ° with the angle of inclination of vertical direction, and namely tiltedly sword 3 is 86 ° with the angle of horizontal direction, and this angle can strengthen oblique sword 3 intensity greatly, and the intensity of whole cutter head 2, tiltedly sword 3 is 5:3.5 with the length ratio of cutting edge 4, and tiltedly sword 3 is suitable with cutting edge 4 ratios, than traditional oblique sword 3 and the more difficult fracture of cutting edge 4.
Visible by reference to the accompanying drawings, this PC/PMMA production and processing cutter, comprise cutter hub 1, one side of cutter hub 1 is cutter head 2, cutter head 2 bottoms are blade, blade comprises that the close oblique sword 3(of mutual inclination is for chip removal) and cutting edge 4(cutting edge), cutting edge 4 is 86 ° with the angle of inclination of vertical direction, tiltedly sword 3 is 3.5:5 with the ratio of the shared whole tool bit diameter width of cutting edge 4.The utility model, oblique sword 3 and cutting edge 4 are crossed swords and are formed sharp point of a knife, point of a knife cutting PC/PMMA, cutting edge 4 is 4 ° with the angle of horizontal direction, this angle can strengthen cutting edge semi-finals degree greatly, and the intensity of whole cutter head 2, and tiltedly sword 3 is 3.5:5 with the diameter width ratio of cutting edge 4, tiltedly sword 3 is suitable with cutting edge 4 ratios, than traditional oblique sword 3 and the more difficult fracture of cutting edge 4.
The width of described cutter head 2 is less than cutter hub 1 width, and cutter head 2 tilts symmetrical towards middle gradual change formation from cutter hub 1 lower end.After angled straight lines gradual change makes point of a knife stressed, power can, equably towards cutter hub 1 diffusion, be avoided stressed and concentrate.
The width of described cutter head 2 is 1/2 ~ 2/3 of cutter hub 1 width.The width of cutter head 2 will guarantee that cutter head 2 is convenient to the power being subject to be delivered to the middle part of cutter hub 1.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned technological means, also comprises the technical scheme being comprised of above technical characterictic.
