Abstract
The utility model discloses a numerically-controlled multi-tooth milling cutter for one-step moulding, comprising a cutter bar and a cutter blade, wherein the cutter blade is installed on the front part of the cutter bar; the cutting edge of the cutter blade is composed of a plurality of parallel cutter teeth; and the cutter blade is eccentrically compacted with the cutter bar via a flat-head bolt and a cone-end bolt. The numerically-controlled multi-tooth milling cutter for one-step moulding disclosed by the utility model avoids the defect that a plurality of grooves is formed by a single-edge numerically-controlled turning tool via step-by-step machining in a traditional machining method, shortens the machining time of a work-piece, and enables the machining chips to be much easily discharged from the cutter. Simultaneously, the cutter blade is easy to replace by being eccentrically compacted via a flat-head bolt and a cone-end bolt, so that the cutter-changing time is shortened.
Description
Technical field
The utility model relates to a kind of milling cutter, particularly relates to the multiple tooth one-shot forming milling cutter of a kind of numerical control.
Background technology
The application of CNC processing technology in machinery manufacturing industry more and more widely compared with traditional process technology, and CNC processing technology is complex-shaped at endoporus, has more advantage in the demanding workpiece processing of precision and fineness.Yet; Present numerically controlled lathe adopts single-blade CNC turning tool technology processing work mostly; This process technology has following shortcoming: 1, turning cutting tool because the turning endoporus is complicated and turning cutting tool adds disconnected the cutting of difficult formation in man-hour, makes that the cutting in the turning cutting tool is difficult to discharge when processing work; Cutting very easily is wrapped in and influences machined surface quality and precision on the cutter, even forges a knife.When 2, adopting the processing of single-blade CNC turning tool to have the workpiece of a plurality of grooves, can only carry out substep turning processing to workpiece and could on workpiece, form a plurality of grooves, working (machining) efficiency is very low.
The utility model content
The purpose of the utility model is to provide a kind of numerical control multiple tooth one-shot forming milling cutter in order to address the above problem, and this cutter can shorten workpiece process time, and can more easily the processing cutting be discharged.
The utility model is realized through following technical scheme:
The utility model comprises blade and knife bar, and said blade is installed in the front portion of said knife bar, and the blade of said blade is made up of several cutters tooth side by side.
Through after being provided with several cutters tooth on the blade, being processed to form a plurality of grooves simultaneously at surface of the work; Avoided traditional processing method single-blade CNC turning tool intelligence to be processed to form the shortcoming of a plurality of grooves through substep; Shorten workpiece process time, and reduced power consumption.
As preferably, said blade and knife bar compress through flat head screw and awl-end screw off-centre.
Through adopting flat head screw and awl-end screw off-centre to compress, only need Panasonic's screw, blade just can take off from knife bar, is easy to carry out the replacing of blade.
The beneficial effect of the utility model is:
Numerical control multiple tooth one-shot forming milling cutter has avoided traditional processing method single-blade CNC turning tool can only be processed to form the shortcoming of a plurality of grooves through substep, has shortened workpiece process time, has improved working (machining) efficiency, and has reduced power consumption.Milling cutter has also overcome turning cutting tool and has been difficult for forming the disconnected shortcoming that is difficult to discharge of cutting and cut.Adopt flat head screw and awl-end screw off-centre to compress simultaneously, when Panasonic's screw, blade is changed easily, and tool change time is short.
Description of drawings
Fig. 1: the structural representation of the utility model;
Fig. 2: the structural representation of blade in the utility model;
Among the figure: 1-blade, 2-knife bar, 3-installing hole, 4-chip area, 5-cutter tooth.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify:
As depicted in figs. 1 and 2, the multiple tooth one-shot forming milling cutter of the utility model numerical control comprises blade 1, knife bar 2, installing hole 3, chip area 4 and cutter tooth 5, and blade 1 is installed in the front portion of knife bar 2, and the blade of said blade is made up of several cutters tooth side by side.Through after being provided with several cutters tooth on the blade, being processed to form a plurality of grooves simultaneously at surface of the work; Avoided traditional processing method single-blade CNC turning tool can only be processed to form the shortcoming of a plurality of grooves through substep; Shorten workpiece process time, and reduced power consumption.Also overcome turning and be difficult for forming the disconnected shortcoming that is difficult to discharge of cutting and cut.Blade 1 compresses through flat head screw and awl-end screw off-centre with knife bar 2.Through adopting flat head screw and awl-end screw off-centre to compress, only need Panasonic's screw, blade just can take off from knife bar, is easy to carry out the replacing of blade.For the fineness that improves tool surface and the smoothness of chip removal, the surface of blade 1 is provided with one deck TiAlN coating.Coating has reduced diffusion and the chemical reaction between cutter and workpiece, thereby has reduced the crescent wearing and tearing.Coated cutting tool has that case hardness height, wearability are good, stable chemical performance, heat-resistant oxidized, characteristic such as friction factor is little and thermal conductivity is low.Knife bar 2 is a cylinder shape knife rod.In order to make arbor stiffness intensity high, durable in use, the hardness of knife bar 2 is 40～45HRC, and knife bar also requires certain toughness with holding capacity and impact.Knife bar is after heat treatment processed, to guarantee required precision.For practicing thrift the cost of charp tool, this Tool Design is a mechanical clamped cutting tool, and this cutter both can be used for the CNC machining center of interlock more than two, also can be used for the numerically controlled lathe through repacking, realizes the milling with whirling cutter processing and forming, also can be used for processing specially on the CNC special purpose machine tool of overcoat.Because therefore this overcoat product endoporus minimum diameter is merely ∮ 18mm., cutter structure must be compact through very, because structure is limit, a slice blade can only be installed.
The operation principle of the utility model: the curve form of workpiece is to be formed by the countless envelope curve of moulding cutting edge on the cutter.The cutter rotary speed is high more, and feed speed is low more, and workpiece surface finish is just high more.These lathes have the infinite stages governing system usually, can satisfy the requirement of this project cutter High-speed machining, and therefore High-speed machining is to improve the prerequisite of working (machining) efficiency under sufficient cooling situation.
The above preferred enforcement that is merely the utility model that discloses can not limit the claim scope of the utility model certainly with this, so according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
Claims (2)
