Abstract
The invention discloses a circular hole cutter for non-metal materials. The circular hole cutter comprises a cutter head (3), a cutter handle (2), a V-shaped notch (6) and an air exhausting hole (1), wherein the cutter head (3) is fixedly connected with the front end of the cutter handle (2); the air exhausting hole (1) is formed in the middle axis of the cutter head (3) and the cutter handle (2). The circular hole cutter is characterized in that the front end of the cutter head (3) is in a cylindrical thin wall structure; the V-shaped notch (6) is formed in the front end of the cutter head (3); an inclined plane cutting edge (4) is arranged on the V-shaped notch (6); the end face of the tail end of the cutter head (3) is an inclined plane; a circular-arc-shaped cutting edge (5) is arranged at the tail end of the cutter head (3). According to the circular hole cutter for the non-metal materials, the processing accuracy, the working efficiency and the safety can be improved effectively, and the rebound resilience of drilling can be reduced effectively; the circular hole cutter is simple in structure, convenient to operate and high in safety.
Description
Technical field
The invention belongs to manufacturing technology field, belong to specifically a kind of cutting knife for non-metal kind material borings such as rubber, plastics.
Background technology
For a long time, when for example rubber carries out Drilling operation to nonmetallic materials, because rubber elastic properties of materials is large, and soft, adopt the very bad processing of holing of standard spiral bit.If rotating speed that need not be too high when bit bore, is easy to knife, on the contrary the basic bundle of drill bit do not go down, do not cut rubber; Penetration of a cutting tool is very large, can add like this danger close in man-hour coming on rubber belt, dangerous, and inefficiency.
Summary of the invention
The object of the invention is to for addressing the above problem, and supplied a kind of circular hole cutting knife simple, non-metal kind material that stock-removing efficiency is high, safe of manufacturing.
Object of the present invention and solve its technical problem underlying and realize by the following technical solutions:
The circular hole cutting knife of non-metal kind material of the present invention, comprise: cutter head, handle of a knife, v-notch, steam vent, this handle of a knife front end is fixedly connected with cutter head, the axis of cutter head and handle of a knife is provided with steam vent, wherein: described cutter head front end is cylindrical shape thin-wall construction, and cutter head front end is provided with v-notch, and v-notch place is provided with inclined-plane cutting edge, the distal end faces of cutter head is clinoplain, and cutter head end is provided with circular arc cutting edge.
The circular hole cutting knife of above-mentioned non-metal kind material, wherein: the v-notch of described cutter head front end is two, is symmetric about the axis of cutter head.
The circular hole cutting knife of above-mentioned non-metal kind material, wherein: the inclination angle of the distal end faces of described cutter head is 5 °.
The circular hole cutting knife of above-mentioned non-metal kind material, wherein: the height of described v-notch is cylindrical shape thin-walled portion lower than cutter head front end.
The circular hole cutting knife of above-mentioned non-metal kind material, wherein: the basil of described circular arc cutting edge is 30 °.
The present invention compared with prior art has obvious advantage and beneficial effect.From above technical scheme, cutter head front end is cylindrical shape thin-wall construction, cutter head front end is provided with v-notch, the distal end faces of cutter head is clinoplain, overcome and adopted common fried dough twist to turn the slow-speed of revolution to be easy to knife, the basic bundle of drill bit does not go down, and does not cut rubber, penetration of a cutting tool is very large, the shortcoming of coming on rubber belt.The inclination angle of the distal end faces of cutter head is 5 °, and the basil of circular arc cutting edge is 30 °, the resilience while reducing drawbore, raising dimensional accuracy and surface smoothness.In a word, the circular hole cutting knife of non-metal kind material of the present invention, the advantage having has that range of work hole resilience wide, that get out is little, size accurately high, any surface finish is high, reduced labour intensity, increase work efficiency, simple to operate and safe feature.

The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the specific embodiment, structure, feature and effect thereof to the circular hole cutting knife of the non-metal kind material proposing according to the present invention, be described in detail as follows.
Referring to Fig. 1 and Fig. 2, a kind of circular hole cutting knife of non-metal kind material, comprise: cutter head 3, handle of a knife 2, v-notch 6, steam vent 1, these handle of a knife 2 front ends are fixedly connected with cutter head 3, and cutter head 3 is provided with steam vent 1 with the axis of handle of a knife 2, wherein: described cutter head 3 front ends are cylindrical shape thin-wall construction, cutter head 3 front ends are provided with v-notch 6, v-notch 6 places are provided with inclined-plane cutting edge 4, and the distal end faces of cutter head 3 is clinoplain, and cutter head 3 ends are provided with circular arc cutting edge 5.The v-notch of described cutter head 3 front ends is two, about the axis of cutter head 3, is symmetric.The inclination angle of the distal end faces of described cutter head 3 is 5 °.The height of described v-notch 6 is cylindrical shape thin-walled portion lower than cutter head 3 front ends.The basil of described circular arc cutting edge 5 is 30 °.
During use, select the bar of T8 steel, bar is modified to HRC27 °～33 °, according to required processing parts aperture finish turning, go out the cylindrical of cutter head 3, bore and expand endoporus, wall thickness is 2～3mm; The little cylindrical car of handle of a knife 2 is to holding suitable size, and bores a steam vent 1(steam vent and can carry out appropriate adjusting according to the size in required processing parts aperture).With handsaw, on cutting knife, process v-notch 6, the height of v-notch 6 is rubber desired thickness, then v-notch 6 both sides files will be repaired to inclined-plane cutting edge 4.It is that the inclined-plane of 5 ° is poured ，Bing bottom surface, angle file into as cutting and repaired circular arc cutting edge 5 that bottom surface file is accomplished to inclination angle.So greatly strengthened non-metal kind material circular hole cutting knife processing dimension accurately, processed surface smoothness, operating efficiency, security and reduced boring resilience.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, any technical solution of the present invention content that do not depart from, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present invention, all still belong in the scope of technical solution of the present invention.
