Description
Technical field
The utility model is suitable for heavy cutting processing technique field, more particularly to a kind of for the indexable circle of heavy cutting
Shape cutter blade.
Background technique
AP1000 nuclear power unit is widely used in China's nuclear power station, and evaporator water chamber head is the core part of the unit,
Material is difficult-to-machine material 508III steel.In evaporator water chamber head heavy type milling process, cutting parameter is big, and (cutting speed is general
For 300 ~ 400m/min, feed speed is 1 ~ 1.2m/min, and for cutting depth up to 4mm or more), cutting force is big, and cutting temperature is high,
Chip is not easily broken, and causes tool wear serious；Water chamber head blank is solid forging shaping, there are surface hard oxide skin,
The defects of forging folds, burning into sand, cutter bears frequency conversion load and thermal shock in milling process, is also easy to produce breakage, and cutter uses the longevity
Order short, while repeatedly tool changing can reduce stock-removing efficiency, increase production cost.
Summary of the invention
The utility model for 508III steel forgings cutting force during heavy cutting is big, cutting temperature is high, chip not
The problems such as frangibility, cutter life are short, stock-removing efficiency is low devises band there are many reinforcing, shock resistance and reduces friction structure
Blade provides a kind of for the indexable circular milling cutter blades of heavy cutting for 508III molten steel room end socket forging machining.
In order to achieve the above object, technical solution adopted in the utility model is:
One kind being used for the indexable circular milling cutter blades of heavy cutting, and insert shape is truncated cone-shaped, blade thickness 3.97mm, on
Knife face diameter is 10.00mm, and blade basal diameter is 7.87mm, and blade hook angle is 10 °, and relief angle is 7 °, and upper knife face design has width
Degree is 0.26mm, and the negative chamfered edge sine wave Circular Nose Cutting Edge that chamfered edge angle is -20 °, blade, which designs, waveform rake face, blade bottom surface
Design has locating slot, and blade medium design has the fastening screw hole for assembling and fixing.
The beneficial effects of the present invention are:
1. the insert shape is truncated cone-shaped, blade thickness 3.97mm, upper knife face diameter is 10.00mm, blade bottom surface
Diameter is 7.87mm, and blade hook angle is 10 °, and relief angle is 7 °, and blade structure is symmetrical, and processing cost is low.
2. the blade design has sine wave Circular Nose Cutting Edge, blade cuts the effect impacted and sheared when workpiece, cutting
In the process by direct stress, sine wave Circular Nose Cutting Edge can effectively reduce cutting force and impact, enhance cutting hardness and shock resistance
Performance improves stock-removing efficiency, slows down blade breakages.
3. the blade design has waveform rake face, and uses periodic sinusoidal waveform, blade is being cut in process
Stress balance when entering and cutting out, cutting is more steady, while reducing the friction area of blade and chip in process, reduces mill
Damage, improves the integral strength of blade.
There is width for 0.26mm 4. the blade designs on upper knife face, the negative chamfered edge that chamfered edge angle is -20 °, reduction is cut
Vibration caused by cutting keeps cutting more steady.Shock resistance is improved, blade cut sword intensity is enhanced, point of a knife is protected, is conducive to
Blade durability is improved, more the mechanical impact load as caused by interrupted cut in adaptation milling process.
5. design has locating slot on the blade bottom surface, can to avoid during heavy cutting as caused by mechanical load
It clamps bad, plays the role of fixed and reinforce, reduce and vibrated caused by cutting, keep cutting more steady, improve cutter life.
