Abstract

Disclosed is a truncated cone high-speed milling cutter. A cutter body is in the shape of a truncated cone, and cutting edges of alloy blades brazed on the conical surface deviate from the axis of the cutter body by a distance B ranging from 5mm to 7mm. The truncated cone high-speed milling cutter is simple in structure, easy in manufacture, low in cost, high in cutting efficiency and particularly suitable for production of high-volume products formed once by means of high-speed cutting.

Description

The truncated cone high-speed milling cutter

Technical field

The utility model belongs to the metal cutting tool technical field, is specifically related to a kind of milling machine and uses the truncated cone high-speed milling cutter.

Background technology

Milling machine is widely used in the machine industry as modern metal cutting processing capital equipment, is the plane, groove, the lathe commonly used of hole and the processing of other molded surface.Normally used cutter has: cylindrical milling cutter, taper-shank cutter, cover face formula milling cutter, face and side cutter, saw blade cutter etc.Though this type milling cutter obtains than high manufacturing accuracy, cutting output is little, and efficient is low, and cost is high, and tipping takes place easily in high-speed cutting, can not satisfy the processing of high efficiency typical products in mass production.

Summary of the invention

The purpose of the utility model provides a kind of simple in structure, and is easy to manufacture, with low cost, and stock-removing efficiency is high, is applicable to that the milling machine of high-speed cutting is used the truncated cone high-speed milling cutter.

The utility model achieves the above object through following technical scheme: a kind of truncated cone high-speed milling cutter, and the cutter hub of this milling cutter is shaped as truncated cone, and what the alloy blade cutting edge of soldering on the cone face departed from the cutter hub axis is 5～7mm apart from B.Alloy blade evenly distributes along the cone surface.

The angle a of said cone is 0＜a＜90.Can be fixed according to the angle of machined surface.

The degree of depth that cutter hub is gone in said alloy blade soldering is 2-4mm.To guarantee to have enough cutting impact resistances.

Said cutter hub divides left and right sides cutter hub.According to the shape of machined surface, can match and use or single use.

The material of cutter hub is a medium carbon steel, and alloy blade is chosen suitable alloy designations according to the material and the hardness that are cut article.

The outstanding advantage of the utility model is:

Said truncated cone high-speed milling cutter is simple in structure, easy to manufacture, with low cost, and stock-removing efficiency is high, is fit to very much the typical products in mass production production of high-speed cutting time processing moulding.

Fig. 2 is the left cone milling cutter vertical view of the said truncated cone high-speed milling cutter of the utility model.

Fig. 3 is the right cone milling cutter construction sketch map of the said truncated cone high-speed milling cutter of the utility model.

Fig. 4 is the vertical view of the right cone milling cutter of the said truncated cone high-speed milling cutter of the utility model.

Be labeled as among the figure: cutter hub 1, alloy blade 2.

The specific embodiment

Below through accompanying drawing and embodiment the technical scheme of the utility model is described further.

Map 1 and Fig. 2, the structure and the connected mode of the said truncated cone high-speed milling cutter of the utility model are: cutter hub 1 be shaped as truncated cone, the distance that the cutting edge of the alloy blade 2 of soldering on the cone face departs from cutter hub 1 axis is 5～7mm.At first the blade grinding is sharp before the use with cutter and tool grinding machine, with cutter hub be installed on the milling machine arbor and locking after, adjust cutter position, can carry out Milling Process.Blade and machined surface form certain gradient during milling, guarantee that every blade all is little by little to cut and break away from finished surface, realizes steadily cutting and helping chip removal.

The utility model milling cutter; Can use separately, promptly process single inclined-plane, also can about the pairing of two cutter hubs use; Can process two inclined planes simultaneously; The blade of two cutter hubs will stagger and relatively installs during use, and the impulsive force that two cutter hubs produce during milling can be cancelled out each other, and produces the steadily effect of cutting.When being used for roughing blade blunt, available abrasive machine hand grinding.

Claims

1. a truncated cone high-speed milling cutter is characterized in that, the cutter hub of this milling cutter is shaped as truncated cone, and what the alloy blade cutting edge of soldering on the cone face departed from the cutter hub axis is 5～7mm apart from B.

2. truncated cone high-speed milling cutter according to claim 1 is characterized in that, the angle a of said cone is 0＜a＜90.

3. truncated cone high-speed milling cutter according to claim 1 is characterized in that, the degree of depth that cutter hub is gone in said alloy blade soldering is 2-4mm.

4. truncated cone high-speed milling cutter according to claim 1 is characterized in that said cutter hub divides left and right sides cutter hub.
