Description
Technical field
This utility model relates to Machining Technology field, specifically, is sphere efficient molding rose drill.
Background technology
Cutter is the instrument in machine-building for machining, also known as cutting element.Most of cutter is that machine is used, but also has hands.Cutter owing to using in machine-building is substantially all for cutting metal material, so " cutter " word is the most just interpreted as metal cutting tool.Drill bit is as an important ingredient in machining cutter, it is mainly used in hole machined, the development of machinery industry at any time, user is proposed higher requirement to the date of delivery of crudy, process reliability, working (machining) efficiency and the cutter of product, the intensity of workpiece material, hardness are the highest, and cutting speed should be the lowest；Otherwise, cutting speed should be higher.Better, cutting speed is the highest for the cutting ability of cutter, the most how to improve the cutting ability of cutter and the process velocity of workpiece is played to the effect of key.In sphere forming operation, typically requiring cooperates by multiple cutter could form sphere on an object, operation is loaded down with trivial details, multiple working procedure gets off, working (machining) efficiency is low, if the sharpness of the blade of cutter is not high enough to, it is impossible to realize high-speed cutting, it is impossible to meet requirement efficient to work pieces process in modern production.
Utility model content
Utility model purpose: for the problem and shortage of above-mentioned existence of the prior art, the purpose of this utility model is to provide sphere efficient molding rose drill.The blade design of bulb part is sharp, makes cutter be suitable for high-speed cutting, uses sphere forming of a cutter, reduces manufacturing procedure.
Technical scheme: for reaching above-mentioned purpose, sphere described in the utility model efficient molding rose drill, including: handle of a knife and blade, the diameter of described blade afterbody is more than the diameter of handle of a knife, the end of described blade is provided with depressed part, described blade head is sequentially provided with bulb cutting edge to afterbody, first ladder cutting edge, ladder angle, second ladder cutting edge, the knife back, described bulb cutting edge includes the cutting edge that 3 structures are identical, described cutting edge is provided with the first arc milling plane, second arc milling face and the 3rd arc milling face, chip area separately designs between the first ladder cutting edge and the second ladder cutting edge, between second ladder cutting edge and the knife back and between the knife back and blade afterbody, described ladder angle is 45 ° with the central axis angle of handle of a knife.
Preferably, described handle of a knife and blade are fixed by welding manner.Welding manner is abundant
Utilize cutter materials so that the cost of charp tool reduces.
Preferably, described handle of a knife and blade are made up of hard alloy material.
Preferably, described handle of a knife and the design of blade concentric.Coordinating with machine tool chief axis at a high speed
During operating, it is possible to well protect cutter, extend cutting-tool's used life.
Preferably, a length of 55mm-56mm of described handle of a knife, described blade a length of
78-79mm。
Preferably, described blade head is 29-30mm to the distance at ladder angle.
Preferably, the outer surface of described handle of a knife and blade is covered with thermal dispersant coatings.Thermal dispersant coatings
The heat produced when being designed for reducing workpiece processing tool, it is to avoid cutter is overheated makes cutter
Produce fragility.
Technique scheme is it can be seen that the beneficial effects of the utility model are:
Sphere described in the utility model efficient molding rose drill, the blade design of bulb part is sharp, makes cutter be suitable for high-speed cutting, uses sphere forming of a cutter, reduces manufacturing procedure, and Type of Welding makes the cost of charp tool reduce, and is suitable for major diameter cutter and makes.
