Abstract
The utility model discloses a drill used for machining carbon fiber reinforced composite materials and a titanium alloy laminated plate. The drill comprises a drill point portion, a chip removal portion and a handle portion, wherein the chip removal portion is provided with a chip removal groove (8) and a secondary cutting edge (7), and the chip removal groove (8) extends from the drill point portion to the handle portion. The drill is characterized in that a drill point angle of the drill point portion is designed as three apex angles, a first apex angle is 105-118 degrees, a second apex angle is 60-65 degrees, a third apex angle is 8-11 degrees, the drill point portion is provided with a front cutter face (1), a rear cutter face (2) and a cross cutter face (3), and the front cutter face (1) and the rear cutter face (2) are intersected to form a main cutting edge (4). According to the drill used for machining carbon fiber reinforced composite materials and the titanium alloy laminated plate, slotting is carried out through a radial large anterior angle, cutters are quite sharp, machined holes are free of the phenomena of tearing and rough edges; by means of the design of the three apex angles, axial force produced in the machining process is reduced, and stratification of machined products is reduced to the lowest.
Description
Technical field
The utility model belongs to the cutting tool technical field, relates to a kind of drill bit of processing carbon fibre reinforced composite and titanium alloy laminated plate.
Background technology
The module laminated body that carbon fibre composite and titanium alloy material consist of is widely used in aircraft wing and tail vane, needs a large amount of riveted joints or bolt apertures in the module laminated body assembling process.In these aeronautical product assembling drillings, best technique is to process simultaneously needed riveted joint or bolt apertures on carbon fibre composite and titanium alloy material module laminated body, and this is the Main Means of guaranteeing laminated material member product bonding strength, rigidity and security.
As seen, boring is very important operation in the carbon fibre composite product assembling processing technology.Because the characteristics such as carbon fibre composite has that hardness is high, intensity is large, poor thermal conductivity, anisotropy, interlaminar strength are low belong to difficult-to-machine material.Carry out the hole at carbon fibre composite and add man-hour, occur very easily that material burn, hole surface are of poor quality, layering, the defective such as tear, thereby cause the carbon fibre composite parts scrap.At present, the drilling technique on carbon fibre composite has been carried out many pilot studies both at home and abroad, also drawn some useful experience and conclusions, but these experiences and conclusion all are only applicable to the process of using plant equipment to hole usually.For manufacturing enterprise, use advanced automation equipment to carry out drilling operation at carbon fibre composite, can bring undoubtedly huge cost to drop into, therefore still selected the hand drill mode that cost is lower, technical experience is relatively ripe than multiple enterprises.Because hand drill is controlled relatively poor at aspects such as cutter stability, feed speed are stable, the therefore manual various holes manufacturing deficiency that on carbon fibre composite, more easily produces during drilling.This has become difficult point and the key point of using composite product to assemble by the traditional handicraft method.The carbon fibre composite performance is crisp, intensity is high, carbon fiber hardness is high, the capacity of heat transmission poor (thermal conductivity factor only be austenitic stainless steel 1/5-1/10), anisotropy, interlaminar strength is low, easily produces bit wear, material burn, layering during cutting under the effect of cutting force, tears and the defective such as burr, especially serious during hand drill, crudy is difficult to guarantee.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of novel suitable processing carbon fibre reinforced composite and the drill bit of titanium alloy laminated plate are provided.
The technical solution of the utility model:
Drill bit comprises apex point section, chip removal section and shank, described chip removal section is provided with chip area and the front cutting edge that extends to shank from apex point section, and the drill point angle of described apex point section is the designs of three drift angles, and the first drift angle is 105 °-118 °, the second drift angle is 60 °-65 °, and the 3rd drift angle is 8 °-11 °.
Described apex point section is provided with rake face, rear knife face and chisel edge; Rake face and rear knife face intersect the formation main cutting edge.
Chisel edge is the S type.
Main cutting edge comprises indent inner edge, Circular Nose Cutting Edge and straight line sword, and the straight line sword is connected with Circular Nose Cutting Edge is round and smooth.
The beneficial effects of the utility model:
1. cutter is very sharp, and the Kong Buhui that processes occurs tearing and the burr phenomenon.Can solve simultaneously material burn problem;
2. technique simply adds drill bit of the present invention by manual air drill and just can process qualified bolt apertures or riveted holes;
3. cutter has used up-to-date nano coating to make tool wear obtain soon good control;
4. adopt the design of three drift angles, lowered the axial force that in process, produces, make the lamination of processed product drop to minimum.

The specific embodiment
The utility model is by the following examples can the utility model will be further described, yet scope of the present utility model is not limited to following embodiment.
Embodiment 1:
Drill bit comprises apex point section, chip removal section and shank, described chip removal section is provided with chip area 8 and the front cutting edge 7 that extends to shank from apex point section, and the drill point angle of described apex point section is the designs of three drift angles, and the first drift angle is 105 °-118 °, the second drift angle is 60 °-65 °, and the 3rd drift angle is 8 °-11 °.Described apex point section is provided with rake face 1, rear knife face 2 and chisel edge 3; Rake face 1 and rear knife face 2 intersect formation main cutting edge 4, and chisel edge 3 is the S type, and main cutting edge 4 comprises indent inner edge 5, Circular Nose Cutting Edge 6 and straight line sword 9, straight line sword 9 and 6 round and smooth connections of Circular Nose Cutting Edge.
The carbon fiber-reinforced resin composite materials of the especially suitable processing high resin of the described drill bit of the present embodiment content and the laminated plate of titanium alloy can guarantee that drill bit pierces reposefully and cuts out in process.The hole surface roughness Ra of processing＜4.8 μ m, the aperture periphery is less than the layering of 1mm, without the cracked phenomenon of fiber.
