Abstract
The present invention provides a kind of design method of large-scale blade roll forging die enabling on 1600mm forging rolls, including first of roll forging die enabling, second roll forging die enabling and the 3rd roll forging die enabling, and three passage roll forging die enabling be all enclosed roll forging die enabling, whole finish roll forging Track character is that the rollforming process in cavity length and die cavity thickness direction occurs for Main change.Main function of first and second forge rolling die during rollforming is to reduce area of section, forming rolls forging is set to pull out in the longitudinal direction, main function of 3rd forge rolling die during rollforming makes shape of the roll forging section almost close to blade, i.e., plays the role of die-forging forming during roll forging；And model cavity and roll forging lower die cavity are asymmetric on roller central line in first, second and third roll forging.
Description
Technical field
This application involves a kind of design method of large-scale blade roll forging die enabling on 1600mm forging rolls, especially a kind of application
In nuclear power field, net finish roll forging mould for conventional island steam turbine ultra-large type final blades.
Background technology
Ultra-large type final blades (67 inches (1700mm) are with blade) are in generation Ⅲ nuclear power conventional island Steam Turbine
Critical component, due to third generation reactor unit capacity than current 1000MW grades capacity increase by 20%~80%, especially
Be it is coastal and in, the north etc. using the area of relatively low coolant water temperature, the deficiency of existing exhaust stage blade leaving area will cause huge
Big steam discharge loss, therefore the ultra-large type final blades for developing bigger leaving area are high capacity highly effective rate nuclear steam turbine hairs
The key of exhibition.
Ultra-large type final blades still determine unit economy, the critical component of reliability.The design and manufacture of linear leaf
It is related to the subjects one such as pneumatic, vibration, intensity, material, antifatigue, water erosion resistent, large forgings forging technology, detection, experimental test
Serial cutting edge technology, only gets up these branches of learning comprehensive, can just produce the ultra-large type final blades of high quality, is nuclear power
Unit provides safeguard.
It is domestic also more than 67 inches especially big without producing before 2011 for 67 inches (1700mm) with blade
The ability of type blade, is completely dependent on import.In June, 2011, Wuxi turbine blade factory spend huge sums the 355MN fly presses of introduction
Operation, and successfully produce 67 inches of nuclear powers and just realize production domesticization with big blade.With the research and development of generation Ⅲ nuclear power, great Rong
The development of high efficiency nuclear steam turbine is measured, the size of final stage moving blade is also increasing, and present 70 inches of grade blades have designed
Into and come into operation.And the forging technology used now is：High-temperature electric resistance furnace heat, 750kg pneumatic hammer bases, die forging process be
Forged twice, then trimming (1200t forcing presses), reheated with 11200t clutch type screw press respectively after heating twice
And it is tempered with fly press school shape, last blade sand cooling.But this forging technology is problem appear to is that forging super thick, overweight
Problem.The research to blade forging forming technology is concentrated mainly on the research in terms of die forging at present, and the present invention is near net-shaped
Roll forging technology shaping blade, the particularly near net-shaped roll forging technical research of super large linear leaf are also rarely reported, this technology can be real
The forging of large-tonnage equipment is produced on present small tonnage plants, and significantly saves equipment investment.This net finish roll forging technique has
Beneficial to the structure organization performance for improving ultra-large type final blades material, the grain size of material, forging flow lines is set to have bigger raising,
So as to strengthen the intensity of blade.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of design of large-scale blade roll forging die enabling on 1600mm forging rolls
Method, net finish roll forging mould include three passage roll forging die enablings, i.e. first of forge rolling die, second forge rolling die, the 3rd roll forging
Mould, and three passage roll forging die enablings are all enclosed roll forging die enablings, first of roll forging die enabling, second roll forging die enabling and the 3rd roll forging
The upper model cavity and lower die cavity of mould are all asymmetric.
Convex high h17=27.4mm, h19=23.4mm, h21=48.4mm, h24=67mm, h25 of first of roll forging upper mold
=89mm, h12=103.9mm, h14=104.8mm, h16=101.8mm；The recessed depth h18=21.4mm of first of roll forging lower die,
H20=23.4mm, h22=42.4mm, h23=67mm, h26=89mm, h11=103.8mm, h13=104.8mm, h15=
101.8mm。
Convex high h27=18.8mm, h29=14mm of second roll forging upper mold, h230=32.6mm, h233=56.5mm,
H234=83mm, h222=99.1mm, h23=103mm, h226=103mm；The recessed depth h28=12.8mm of second roll forging lower die,
H229=13.9mm, h231=32.6mm, h232=56.5mm, h235=83mm, h21=99.1mm, h24=103mm, h25
=103mm.
Convex high h38=27.4mm, h39=23.4mm of 3rd roll forging upper mold, h341=42.4mm, h342=67mm,
H344=89mm, h32=103.9mm, h34=104.8mm, h36=101.8mm；The recessed depth h37=of 3rd roll forging lower die
27.4mm, h339=23.4mm, h340=42.4mm, h343=67mm, h345=89mm, h31=103.8mm, h33=
104.8mm, h35=101.8mm.
It is an advantage of the invention that on a kind of 1600mm forging rolls large-scale blade roll forging die enabling design method, in roll forging process
In make roll forging part close to blade net shape, the cross-sectional width size of same position is kept not during the roll forging of three passages
Become, and thickness is reduced, so that length direction increase reaches final blade dimensions, and whole process with this roll forging technology
Occur without overlap.This net finish roll forging technology not only improves stock utilization, but also is improved the grain size of material, energy
Forming more preferable metal streamline makes the performance of blade be greatly improved.
