Forging, evaporator water chamber head are integral forging and forming, and there are many forging defects for work surface, such as: forging shovel ditch, oxidation
Skin, forge crack and metal covering etc..Currently, the cutting way of processing water chamber head part mainly includes Large Heavy-duty Turning and again
Type milling two ways.Evaporator water chamber head heavy parts are processed as finished product, material removing rate is 70% or more；It is processed
Journey cutting depth apUp to 30mm, generates biggish cutting force, and cutter is easy to be formed at cutting edge by higher mechanical shock
Different degrees of breakage causes tipping phenomenon of rupture；And generate a large amount of cutting heats during the cutting process and be deposited in cutting zone,
Knife-bits bonding phenomenon is easily caused, causes cutter life low, number of changing knife is frequent, while in Large Heavy-duty Turning or heavy milling
Cut in processing blade used in terms of it is different, can not be general mutually, exist have a single function, application range
The problems such as narrow, poor universality, lead to that processing efficiency is low.
Summary of the invention
The utility model aim is to provide one kind for the indexable turnning and milling composite blade of big cutting-in hogging machining, mainly solves
During cutting using water chamber head as typical part hogging machining, larger cutting parameter rushes cutter by Frequency varying load machinery
Hit, thermal shock easily causes cutter tipping, fracture, and cutter radiating condition is poor during the cutting process, and cutting temperature is excessively high to be caused
The problems such as knife-bits bonding failure.
In order to achieve the above objectives, the utility model takes the technical solution to be: one kind is for big cutting-in hogging machining index lathe
Composite blade is milled, the blade is truncated rectangular pyramids shape, and four outer edges of blade rake face are machined with negative chamfered edge cutting edge respectively,
Circular Nose Cutting Edge transition is equipped between every adjacent two negative chamfered edge cutting edges；Cutter upper surface is equipped with square protruding platform, square protruding
Platform side and cutter rake face form trapezoidal chip-breaker, and reinforcing rib is equipped on blade rake face；Blade upper surface is rectangular convex
It rises and is equipped with fastening screw hole at platform geometric center.
The utility model has the beneficial effects that
The utility model is designed using monolithic construction, can reduce blade processing cost；Blade upper surface is equipped with rectangular convex
Platform is played, blade integral strength is increased, improves blade shock resistance, when cutting parameter is larger, cutter is able to maintain well
Stress, be not likely to produce tipping phenomenon of rupture.
Four outer edges of blade rake face process four negative chamfered edge cutting edges, a negative chamfered edge cutting edge failure respectively
Afterwards, another negative chamfered edge cutting edge will be can be used to continue machining after its 90 ° of indexings, to improve processing efficiency, dropped
Low use cost.
Blade uses negative chamfered edge cutting edge design method, can reinforce edge strength, generate in reduction cutting process
Vibration keeps cutting more steady；Per Circular Nose Cutting Edge transition is passed through between adjacent two negative chamfered edge cutting edges, point of a knife intensity can be enhanced,
Improve blade service life.
Blade rake face is equipped with rugby shape protrusion, and blade chip breaking ability can be improved in chip when flowing through rugby shape protrusion,
Slow down rake wear；Reduce chip and tool contact area simultaneously, increase the effective heat dissipation area of cutter, reduces cutting temperature.
Trapezoidal chip-breaker is formed between blade upper surface square protruding platform side and rake face, makes chip that curling occur and becomes
Shape improves blade chip-breaking performance；It, can if a small amount of cutting fluid can also be accommodated in trapezoidal chip-breaker using cutting fluid
The effect of its cooling and lubricating is given full play to, keeps chip outflow more smooth, cooling velocity is faster.
It is located on blade rake face in the trapezoidal chip-breaker of blade and is equipped with cutting edge reinforcing rib, can avoid leading to knife because of tipping
Piece failure increases edge strength, while playing segmentation and protective effect to major-minor cutting edge, improves cutting edge resisting breakage performance.
Blade is mounted on turning tool rod or facing cutter by the fastening screw hole at blade geometric center, can quickly be revolved
Rotor piece improves the service efficiency and processing efficiency of blade；It can play the role of fixing to clamp simultaneously, prevent blade processed
It rotates or slides due to the effect by cutting force or frictional force in journey.
