Abstract

The utility model relates to the technical field of milling cutters, in particular to a milling cutter for processing plastic workpieces. Aiming at the defects that chip removal is unsmooth and the plastic workpieces are easy to stick on the milling cutter when a common milling cutter directly processes the plastic workpieces in the prior art, the utility model provides a leaf-shaped milling cutter. The leaf-shaped milling cutter comprises a cutter handle, a cutter bar and a cutter bit which is connected with the front end of the cutter bar, wherein the cutter bit comprises a plurality of evenly distributed leaf-shaped blades; both sides of the leaf-shaped blades are arcs the concave directions of which are consistent; the tangent included angle of the arcs of both sides at the cutter point is 30-60 degrees; and the tangent included angle of the arcs of both sides at the cutter root of the leaf-shaped blades is 15-45 degrees. The utility model can be used for directly processing various workpieces, in particular to the plastic workpieces, can make the chip removal smooth, improves the product quality and improves the working efficiency.

Description

A kind of leaf milling cutter
Technical field
The utility model relates to the milling cutter technical field, relates in particular to a kind of milling cutter that is used for plastics part processing.
Background technology
In the prior art, exist many can be to the milling cutter of metal works smear metal processing, typically, notification number is that the utility model of CN201239818Y discloses a kind of T type milling cutter, comprise handle of a knife and cutter head, its main points are that said cutter head is side set and both sides tooth punching, and both sides tooth degree is 1-2 °, and side set tooth degree is 10-12 °.This utility model cutting is light and handy, and part stress is even, and the vibrations of lathe obviously alleviate, and the variation of T type groove horizontal direction can be controlled in the 0.1mm, adopts this cutter to carry out interrupted cut, the efficient height, and surface quality of workpieces is good, and cutter consumption is few.But its cutter tooth is a linear pattern, and because the characteristic of plastics, when this T type milling cutter was applied to make plastics part, the milling cutter chip removal had some setbacks, and easily sticking cutter influences crudy.Therefore need a kind of milling cutter, can improve crudy the plastics part processing that is well on.
The purpose of this utility model is to overcome plain cutter in the prior art and plastics part is directly added the chip removal that exists man-hour has some setbacks, the defective of easily sticking cutter provides a kind of leaf milling cutter, can especially directly process for working of plastics various workpiece, can chip removal smooth and easy, guarantee crudy.
Summary of the invention
The utility model directly adds the chip removal that exists man-hour at plain cutter in the above-mentioned prior art to plastics part and has some setbacks, and easily the defective of sticking cutter provides a kind of leaf milling cutter.
The utility model mainly solves the problems of the technologies described above by the following technical programs: a kind of leaf milling cutter, comprise handle of a knife, knife bar and the cutter head that is connected with the knife bar front end, cutter head is made up of the equally distributed leaf blade of multi-disc, the both sides of leaf blade are recessed arc to unanimity, the tangent line angle of both sides arc at the point of a knife place is 30 ° ~ 60 °, the tangent line angle of both sides arc at the cutter root place of leaf blade is 15 ° ~ 45 °, and cutter head and handle of a knife, knife bar centering are installed, and guarantee machining accuracy.When entering cutting, the point of a knife cutting force of leaf blade is big, and when withdrawing from cutting, leaf blade can withdraw from stably.Leaf blade is recessed big to chip space, centrifugal the dishing out that cutting energy is quick and smooth.
As a kind of preferred version of such scheme, it is characterized in that the junction between the described leaf blade is an arc transition, can reduce stress and concentrate, improve local pressure, thereby improve milling cutter service life.
As a kind of preferred version of such scheme, it is characterized in that described cutter head and knife bar front end by being threaded, can be convenient for changing the cutter head of damage, improve economy.
As a kind of preferred version of such scheme, it is characterized in that described leaf blade is two, chip space is big, makes quick and smooth the dishing out of cutting, guarantees carrying out smoothly of processing.
Therefore, the utility model can especially directly be processed for working of plastics various workpiece, and is can chip removal smooth and easy, improved product quality, improved operating efficiency.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the utility model from cutter head a kind of schematic diagram of direction down;
Fig. 3 is a kind of schematic diagram of the utility model implementation process.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings the technical solution of the utility model is described in further detail.
Shown in accompanying drawing 1, accompanying drawing 2, a kind of leaf milling cutter, comprise handle of a knife 1, knife bar 2 and the cutter head 3 that is connected with the knife bar front end, it is characterized in that, described cutter head is made up of the equally distributed leaf blade 31 of multi-disc, the both sides of leaf blade are recessed arc to unanimity, and the tangent line angle of both sides arc at the point of a knife place is 30 °, and the both sides arc is 30 ° at the tangent line angle at the cutter root place of leaf blade.When entering cutting, the point of a knife cutting force of leaf blade is big, and when withdrawing from cutting, leaf blade can withdraw from stably.Cutter head and handle of a knife, knife bar centering are installed, and guarantee machining accuracy.Junction between the leaf blade is an arc transition, can reduce stress and concentrate, and improves local pressure.Cutter head and knife bar front end can be convenient for changing the cutter head of damage by being threaded, and improve economy.Leaf blade is two, and chip space is big, makes quick and smooth the dishing out of cutting, guarantees carrying out smoothly of processing.
As shown in Figure 3, adopt this leaf milling cutter on plastics part 4, circumferentially to mill out side position groove 41 one, workpiece is fixed on the rotary table, with the milling handle cutter chuck of packing into, adjust the tool position, make the position to be processed of leaf blade point of a knife alignment pieces, apply power, leaf blade wedging workpiece begins cutting, cutting is dished out from curved channel between blade is centrifugal quick and smoothly, avoids sticking cutter, along with the rotation of rotary table, leaf blade is finished the circumference cutting to workpiece, finally mills out peripheral side position groove.
Especially, the utility model is applied in making plastic shaping exemplar workshop, because plain cutter can not directly be processed the side position of exemplar, the side position groove or the line attractive in appearance of a lot of exemplars all can't directly cut, exemplar need be disassembled processing, whole by the bonding one-tenth of post processing again, so just influenced the attractive in appearance and bulk strength of exemplar, and after using this leaf milling cutter, implementation process is identical with the foregoing description, can the side position of plastic shaping exemplar directly be processed, and has reduced the fractionation operation of plastic shaping exemplar, improve operating efficiency, improved product quality.
The utility model can especially directly be processed for working of plastics various workpiece, and is can chip removal smooth and easy, improved product quality, improved operating efficiency.
