Abstract
The invention relates to a spiral type chip dividing drill, which comprises a clamping part (1), a deep cutting edge part (2), a circular arc saw tooth cutting edge part (3) and a tapered cutting edge part (4), wherein the clamping part (1) is longer than the ordinary clamping part, and the front end of the deep cutting edge part (2) is additionally provided with a circular arc surface. The spiral type chip dividing drill is characterized in that the circular arc saw tooth cutting edge part (3) is a cutter point back part and is in a six-blade circular arc-shaped spiral saw tooth shape. Through the structure, by aiming at the characteristics of various special-shaped elements, the thorough innovation is carried out in aspects of cutter length, diameter, angle, circular arc degree and the like. The processing of various curve surfaces can be completed by one cutter as much as possible.
Description
Technical field
The invention belongs to the automatic equipment of the deburring of the special-shaped aluminium castings such as automobile and motorcycle wheel hub and engine, especially bore about a kind of spiral minute bits.
Background technology
The fluted drill that boring is used on all kinds of another parts is that a kind of very economical is practical, and adaptable instrument all takes much count of raising and innovation to the Twist Drill technology both at home and abroad.Domestic cutter or the manual fluted drill that grinds that mostly still uses general machine tool to use, this cutter just can't be processed for some specific curved surfaces, also have machine tool to add man-hour owing to considering stressed large problem, so cutter is not very long, this has just brought the interior burr of some deep holes of shaped piece to process and has put in place.The cutter that grinds by hand can satisfy on the length of cutter and angle, but grinding of some arc surfaces on cutter may just be difficult to realize, occurs irregular cut channel when causing processing curve.
Summary of the invention
For above deficiency, the novel purpose of this use is to provide a kind of spiral minute bits to bore, and is to be improved by original six sword vertical drills, lengthened the part of clamping, the increase of cutter front end has an arc surface, and point of a knife is one section cone angle, as much as possible allows a cutter complete the processing of various curved surfaces.
Technical scheme of the present invention is achieved in the following ways: bits bored in spiral minute, by retained part, dark cutting edge part, circular arc serrated knife blade part and tapering knife edge part, the length that described retained part is more common, the front end of dark cutting edge part is set up an arc surface, it is characterized in that: described circular arc serrated knife blade partly for the point of a knife rear portion, is six sword circular arc spiral saw dentations.
Described circular arc serrated knife blade partly is provided with two main cutting edges and chisel edge, and chisel edge is comprised of two long chisel edges and a hyphen sword.
Angle between described two main cutting edges is 135 ° ± 1 °.
The present invention is to be improved by original six sword vertical drills, and because burr processing does not need very large cutting force, this cutter has lengthened the part of clamping, and it can be processed the darker hole of the degree of depth; The cutter middle part keeps the original apperance of original six sword slotting cutters, and it has guaranteed the good cutting power of cutter; The increase of cutter front end has an arc surface, and cutter relieving has ability and processes concave Iy curved, can allow the level and smooth zero defect of cut channel of cutter, and point of a knife is one section cone angle, can rise up into tiny corner burr is removed.By the feature to various shaped pieces, carried out innovation thoroughly at aspects such as tool length, diameter, angle, circular arc degree.The cutter that allows as much as possible can be completed the processing of various curved surfaces.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the schematic diagram of circular arc serrated knife blade part.
In figure: 1 retained part, the 2 quick cutting tips of dark cutting edge, 3 circular arc serrated knife blade parts, 4 tapering knife edge parts, 5 two main cutting edges, 6 long chisel edges, 7 hyphen swords.
The specific embodiment
Known by Fig. 1, bits bored in spiral minute, formed by retained part 1, dark cutting edge part 2, circular arc serrated knife blade part 3, tapering knife edge part 4, two main cutting edges 5, long chisel edge 6 and hyphen swords 7, the more common length of described retained part 1, the front end of dark cutting edge part 2 is set up an arc surface.Circular arc serrated knife blade part 3 is the point of a knife rear portion, is six sword circular arc spiral saw dentations.The point of a knife of tapering knife edge part 4 is conical, and blade is the high density helical cutting edge, and cutting edge is more shallow, and diameter is thinner.
Being known by Fig. 2, is the schematic diagram of circular arc serrated knife blade part.Circular arc serrated knife blade part 3 comprises that two main cutting edges 5, two chisel edges 6 and a hyphen sword 7 form, and the angle between two main cutting edges is 135 ° ± 1 °.
The present invention, six sword processing of slotting cutter formula in the middle of using when the general workpiece burr of processing require process velocity fast, it is whole the darkest cutting edge in cutter, stock-removing efficiency is the highest.Use Roound edge when processing curve and unmanageable plane, it is good that Roound edge is followed workpiece shape performance, also easily adjust to the right place adding the man-hour cutter-orientation, this place's blade spiral angle all bores consistent with spiral minute bits with pitch, blade is zigzag, chip removal performance when jagged blade has improved Tool in Cutting, making it when high-speed cutting not can swaging clamp, improves the stability of work.The tapering knife edge part be process tiny burr and in the situation that in some small spaces cutter can't all rise up into and use, its cutting edge is the high density screw type, due to consider this part be cutter holding capacity minimum the cutting edge roundness of all designs of part more shallow.
Claims (3)
1. spiral minute bits bore, comprise retained part (1), dark cutting edge part (2), circular arc serrated knife blade part (3) and tapering knife edge part (4), the more common length of described retained part (1), (2) front end of dark cutting edge part is set up an arc surface, it is characterized in that: described circular arc serrated knife blade part (3) is six sword circular arc spiral saw dentations for the point of a knife rear portion.
2. spiral minute according to claim 1 bits bore, and it is characterized in that: described circular arc serrated knife blade part (3) is provided with two main cutting edges (5) and chisel edge, and chisel edge is comprised of two long chisel edges (6) and a hyphen sword (7).
3. spiral minute according to claim 2 bits bore, and it is characterized in that: the angle between described two main cutting edges (5) is 135 ° ± 1 °.
