Abstract

The utility model is a metal cutting tool, in particular an efficient cutting milling cutter with an indexable spiral taper. The cutting milling cutter comprises a handle and a tool bit, wherein the tool bit is a tapered cone; at least two sets of spiral slots are uniformly distributed on the cone; blades are fixed at lower edges of the spiral slots; the blades in a group are overlapped with each other; and the blades on a conical surface are such arranged that a connection of central points of outer cutting edges of the blades is an involute spiral line. The efficient cutting milling cutter can conveniently finish cutting processes of complicated structures, with a cutting efficiency 7-10 times faster than a high-sped steel cutter and 4-6 times faster than a welding cutter. Moreover, cutter body thereof is not easy to damage; and the use cost is about 2/3 less than the high-sped steel cutter and the welding cutter.

Description

Spiral tapering high-efficient cutting milling cutter
Technical field
The utility model is a metal cutting tool, particularly indexable spiral tapering high-efficient cutting milling cutter.
Background technology
To today that high-efficient automatic develops, it is especially important that the innovation of metal cutting tool technology just seems in Machine Manufacturing Technology.Particularly in recent years with Digit Control Machine Tool, machining center is the modern high accuracy of representative, the use of high efficiency lathe, and to tool precision, cutting ability, functional reliability and processing performance are had higher requirement.
At present, the development of cutting-tool engineering has both at home and abroad obtained significant progress, the application of hard alloy cutter also more and more widely, thereby make the development of cutter enter at a high speed the high-efficient development stage.Indexable milling cutter development at home and abroad is also very fast, and most of enterprise takes coating technology to improve cutter life, improves cutting speed and stock-removing efficiency simultaneously.
But the development of these cutters remains with the comparatively simple face milling cutters of structure, and slotting cutter and cylindrical bar milling cutter are main.These cutters can only satisfy the comparatively simple operation of those structures, as mill face, mill step, fluting etc.And for those structures than complicated step, as bevel, open operation such as tapering groove, can only rely on the Digit Control Machine Tool copy milling, same operation needs repeatedly feed just can finish during copying, the efficient of copy milling is lower, can not satisfy the market demand of Modern High-Speed, High-efficient Production.And the cutter of these labyrinths is at present still based on high-speed steel tool and brazed shank tool, the major advantage of these cutters be make simple relatively, the precision height; And that shortcoming is a cutting speed is low, efficient is low, cost is high.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of cutting speed fast, and the stock-removing efficiency height is conveniently finished the spiral tapering high-efficient cutting milling cutter of complicated cutting process of structure.
Solution of the present utility model is: a kind of spiral tapering high-efficient cutting milling cutter, comprise handle of a knife and cutter head, cutter head is the cone of band tapering, be characterized on cone, being uniform-distribution with at least 2 group helicla flutes, be screwed blade at the spiral fluted lower limb, overlap joint mutually between one group of blade, the arrangement of blade on taper seat is that the central point line of cutting edge outside the blade is for gradually opening helix.
Its course of work is: lathe drives the handle of a knife rotation, handle of a knife drives the cutter head rotation, and the blade elder generation contact workpiece at the helicla flute front end participates in cutting like this, and then second, third,,,,,, a blade participates in cutting successively, remove pre-chipping allowance, reach the purpose of processing.
Can make formed gradually open after the face that helix projects to cone center line place of the central point line of the outer cutting edge of blade become 30 ° of-48 ° of angles with the cone center line in the solution of the present utility model.Complete large helix angle cutting edge of corresponding formation has reduced cutting resistance, can be shaped by a cutter for the common conical surfaces such as groove.
The tapering that can make cutter head in the solution of the present utility model is 30 °-120 °.At the cone of this scope, the cutting milling cutter cutting effect of its formation is best.
Can make in the solution of the present utility model to be uniform-distribution with 3 groups of helicla flutes on the cone, the blade that is fixed in the helicla flute is 3 groups.
Advantage of the present utility model:
(1) normally chip breaking chip removal, blade is evenly distributed in the helicla flute of taper seat, plays bifurcating chip action, and the blade in the same helicla flute overlaps mutually simultaneously, forms complete cutting edge, the stock-removing efficiency height.
(2) cutting speed is fast: the indexable spiral tapering high-efficient cutting milling cutter and the cutter comparison amount of feeding of the same type can improve 1.5-2 doubly, by using coated chip, cutting speed can improve 2-3 doubly, and for those structures than complicated step, as bevel, open operations such as tapering groove, can only rely on the Digit Control Machine Tool copy milling, same operation needs repeatedly feed just can finish during copying.
(3) use cost is low: welding cutter cutting edge can only integral body scrap, and indexable spiral tapering high-efficient cutting cutting plate for milling cutters is fixed by screw in case damage just can't be remedied, and changes blade and just can recover its cutting function.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is Fig. 1 left view.
The specific embodiment
The utility model embodiment as Fig. 1, Fig. 2, shown in, a kind of spiral tapering high-efficient cutting milling cutter, comprise handle of a knife 1 and cutter head 2, cutter head 2 is the cone of band tapering, the cone tapering is 30 °-120 °, on cone, be uniform-distribution with 3 groups of helicla flutes 3, lower limb screw 4 fixed blades 5 at helicla flute 3, overlap joint mutually between one group of blade 5, the central point line of blade 5 outer cutting edges is formed gradually to be opened the face that helix projects to cone center line place and becomes 30 ° of-48 ° of angles afterwards with the cone center line.
The spiral tapering high-efficient cutting milling cutter and the existing milling cutter result of the test of present embodiment are as follows:
From above table data relatively, the surface roughness of present embodiment spiral tapering high-efficient cutting milling cutter machined surface can reach Ra3.2, and cutting linear velocity can reach 150m/min~200m/min, and processing length reaches 20 meters.In working (machining) efficiency, crudy all is better than existing milling cutter on several main cutter performance assessment criteria such as cutter life.
