Abstract
Due to the fact that powdery cutting chips will be generated in the drilling process of carbon fiber composite materials, the environment is polluted, meanwhile, the body health of workers is affected, and when a dust collector is used for sucking away cutting chips in a manual mode at present, direct suction cannot be achieved during generation due to the fact that suction can be achieved only from a hole inlet region, the invention relates to a drill bit capable of directly discharging cutting chips in the machining process, in particular to an air suction type automatic chip removal drill bit so as to achieve green machining of the carbon fiber composite materials. The air suction type automatic chip removal drill bit for CFRP machining comprises a drill body 1, a chip suction duct 2, a chip removal duct 3, a main cutting edge 4, a wiper 5, a spiral angle 6 and a balanced edge 7. According to the selective basis of the air suction type automatic chip removal drill bit, the drill bits of different diameters are adopted for different materials, cutting chips generated in the machining process can be smoothly discharged by reasonably designing the positions and sizes of air suction holes and chip removal holes, and the CFRP machining quality is ensured by selecting and reasonably designing the angles of the main cutting edge, the wiper and the spiral angle and reasonably designing the length of the balanced edge.
Description
Technical field
The present invention is applicable to comprise the chip removal process that carbon fibre composite processing is pulverous processing at interior all chips. Be specifically related to a kind of for air suction type from the air suction type of chip removal system from chip-removal drill bit.
Background technology
Carbon fibre composite drilling process can produce Powdered smear metal, and contaminated environment affects the healthy of workman simultaneously. And at present, adopt manual type to utilize dust catcher that smear metal is siphoned away, owing to drawing from hole entrance area, and can not in the time producing, directly draw. For this subject matter, the present invention proposed to design a kind of can be in process directly by the drill bit of chip discharge---air suction type is from chip-removal drill bit, the moment that smear metal is being produced, just can be by the suction hole of cutter, enter storage device through handle of a knife, main shaft etc., provide a kind of new-type cutter for realizing the processing of CFRP environmental protection.
Summary of the invention
The present invention designed a kind of CFRP processing with air suction type from chip-removal drill bit, its objective is that the smear metal in order to make to produce can be got rid of in time in process, realize green processing.
For achieving the above object, the technical solution used in the present invention is: a kind of CFRP processing mainly comprises from drill bit described in chip-removal drill bit with air suction type: the structures such as drill body, flock silk sucking opening road, debris port, main cutting edge, wiper edges, helical angle, weighing apparatus sword.
Described drill bit is applicable to the chip removal process that all chips are pulverous processing.
Described drill bit has debris port, and whether the size of its channel diameter, duct quantity, location class duct, duct shape can and can eject definite smear metal by the shape of drill bit completely.
Described drill bit has flock silk sucking opening road, and whether the size of its channel diameter, duct quantity, location class duct, duct shape can and can eject definite smear metal by the shape of drill bit completely.
The drill body that described air suction type is cut drill bit from row can be straight trough drill bit, spiral fluted drill bit, bore the drill bits such as ream one drill bit, treapanning drill, dagger drill bit, and it should have flock silk sucking opening road and debris port, and can be Powdered smear metal sucking-off.
The blade that described air suction type is cut drill bit from row can be to be one with drill body, also can be being welded to after blade on drill body, and it should have flock silk sucking opening road and debris port, and can be Powdered cutting sucking-off, and can realize the processing that CFRP guarantees both quality and quantity.
Described air suction type is cut the cutting edge of drill bit from row, can be main cutting edge and wiper edges and deposit, can be also to only have main cutting edge, and it should have flock silk sucking opening road and debris port, and can be Powdered smear metal sucking-off, and can realize the processing that CFRP guarantees both quality and quantity.
The operation principle of the air-breathing chip removal of described cutter, in the time that lathe starts, main shaft drives drill bit to carry out drilling and add man-hour, produce negative pressure by air-breathing/storage device, make the flock silk sucking opening road of drill bit absorb the Powdered smear metal that drill bit produces in drilling processing, smear metal is cut duct through debris port and the tangent row who answers and bits is transported in air-breathing/storage device, to realize the green processing of CFRP.
Beneficial effect of the present invention
For CFRP processing with air suction type from chip-removal drill bit, the effect of his maximum is discharged from air-breathing duct and debris port timely for CFRP being added to the smear metal producing man-hour, the smear metal contaminated environment being produced to avoid and the health that affects operator. (2) can make its drill bit that is applicable to any diameter of processing corresponding composite by the position, size and the quantity that change the air-breathing duct of drill bit, can both reach needed suction bits effect. (3) can make its drill bit that is applicable to any diameter of processing corresponding composite by the position, size and the quantity that change drill bit debris port, can both reach the effect of in time cutting being discharged.
Brief description of the drawings
Fig. 1 is that CFRP processing air suction type is intended to from chip-removal drill bit structure.
Wherein: 1-drill body, 2-flock silk sucking opening road, 3-debris port, 4-main cutting edge, 5-wiper edges, 6-helical angle.
