The quality of nuclear forging is to influence nuclear power generating equipment quality and the key in life-span.Nuclear power low pressure rotor forging is nuclear power machine
Group key components and parts, such volume of part is larger, forming difficulty, and production cost is high, and long-term work is therefore right in adverse circumstances
The combination property of part proposes high requirement.When being pulled out to rotor forging, typically using common flat anvil or without Mannesmann
Forging method (Free from Mannesmann effect, FM) method of effect, the deformation of forging are only operated at forging surface district
Domain, the as-forged condition in center portion region is not substantially changed.It is proposed V-shape anvil forging method to nuclear power low pressure rotor forging at this stage
When part is pulled out, its deformation zone stress state is good, and central area forging permeability is good.
The conventional nuclear power low pressure turn for being made as entirety, certain diameter scope can only being directed to of V-shape anvil block that V-shape anvil technique uses
Sub- forging forging.With the diameter increase of nuclear power low pressure rotor forging, and the V-shape anvil block of bigger specification is remake, certain
The waste of resource is caused in degree, adds production cost.
The content of the invention
Technical problem：The purpose of this utility model is to provide a kind of combined type V-shape anvil, in the pulling to nuclear power low pressure rotor
During, required according to the difference to V-shape anvil size, replacing activity anvil block, avoid the V-shape anvil block of remanufacturing, save significantly
About actual cost.
Technical scheme：A kind of combined type V-shape anvil of the present utility model includes：V-shape anvil base and movable anvil block；In V-shape anvil
Elongated dovetail groove is offered on the platform of base the right and left respectively, movable anvil block there are two pieces, respectively positioned at V-shape anvil base or so
On the platform on both sides, the dovetail coordinated with the dovetail groove is offered respectively on the platform of movable anvil block lower end；Movable anvil
The V-arrangement of block extends side and the V-shaped edge of V-shape anvil base is located in approximately the same plane, when the dovetail of movable anvil block lower end inserts V-arrangement
After the dovetail groove of anvil base, the V-shaped groove of V-shape anvil base is just extended.
Wherein：
The angle of the V-shaped groove of the V-shape anvil base is 60-120 °, and movable anvil block is trapezoidal by two of a variety of height dimensions
Block forms.
The V-shape anvil base is one v-depression of processing above square base, is provided with v-depression left and right plane
Elongated dovetail groove.
By dovetail groove into being slidably matched, gap is not easy to be more than the movable anvil block of the V-shape anvil base and its right and left
0.1mm。
The size relationship of the V-shape anvil base is：The long L1 of square takes 2800~3500mm, width W1 to take 800~1200mm,
Height H1 takes 800~1200mm.Depth of groove H2 takes 400~600mm, and the angle of V-shaped groove is 90 °.
The movable anvil block is shaped as trapezoid block, movable anvil block sidepiece inclined-plane with it is horizontal to angle be 45 °, with V-shape anvil
The angle of the V-shaped groove of base is consistent, and height H3 takes 300~1200mm, and bottom is a dovetail, and length L2 takes 400~
600mm, height H4 take 200~300mm.
Beneficial effect：Benefit caused by the utility model, the index reached.
1. by combined type V-shape anvil, the processing dimension scope of pulling can be increased, reduce different size V-shape anvils in production
Demand, saved cost, improved processing flexibility ratio.
, also need not be overall if trapezoidal supplement block surface has serious wear after 2. combined type V-shape anvil uses a period of time
V-shape anvil block is reformed, trapezoidal supplement block need to only be removed, separately be done two pieces and change can working on, greatly save cost.
Brief description of the drawings
Fig. 1 is the side structure schematic view of combined type V-shape anvil, wherein having：V-shape anvil base 1, movable anvil block 2.
Fig. 2 is the side structure schematic view of V-shape anvil base 1,

Embodiment
Illustrated according to encompassed content
The structure of combined type V-shape anvil of the present utility model as shown in figure 1, the combined type V-shape anvil by V-shape anvil base 1 and 2
Movable anvil block 2 is formed, and the two is combined by oat tail groove structure.Wherein movable anvil block 2 can be by two of sizes
Anvil block forms, and V-shape anvil base 1 forms different size of V combined types shape anvil, realizes the pulling process of nuclear power low pressure rotor.
Fig. 2 is V-shape anvil base 1, and a v-depression is processed above square base, is provided with v-depression left and right plane
Elongated notch, in dove-tail.The long L1 of square take 2800~3500mm, width W1 take 800~1200mm, height H1 take 800~
1200mm.Depth of groove H2 takes 400~600mm, and angle is 90 °.
