In forging scheme, it can not realize and being switched fast for anvil block configuration is descended in same pneumatic hammer, constrain forging production efficiency.
Utility model content
The utility model provides a kind of forging special lower anvil block of steam turbine steel, to solve above-mentioned prior art deficiency.Adopt
Existing anvil block structure is replaced with the two groups of anvil that can be rotated on base block monomers, feelings are set to the pad of anvil block monomer by adjusting cushion block
Condition, it is quick to realize lower anvil block configuration switching, so as to meet the different forging process requirements of steam turbine steel, be advantageous to improve production
Efficiency.
In order to realize the purpose of this utility model, intend using following technology：
One kind forging special lower anvil block of steam turbine steel, it is characterised in that including base, extension plate, anvil block monomer and pad
Block, the extension plate are fixedly installed at the base upper surface transverse ends extended line respectively, and the anvil block monomer is two pieces,
The both sides for being fixed on the base longitudinal central axis line are respectively articulated with, the cushion block is movably set on the extension plate.
Further, the base upper surface is provided with groove close to end along longitudinal direction, and the cushion block is wedge-shaped mesa-shaped, bottom
Close to end along longitudinal direction provided with the fin with the groove match.
Further, the anvil block monomer end bottom is provided with breach.
Further, the base position between the two anvil block monomers is provided with the abaculus of triangular prism shape.
Further, the cushion block end is provided with push rod, and the push rod end is provided with collet.
Further, the cushion block selects pressure-resistant hard metal material.
The beneficial effects of the utility model are：
1st, the utility model replaces existing anvil block structure using two groups of anvil block monomers that can be rotated on base, passes through adjustment
Cushion block sets situation to the pad of anvil block monomer, quick to realize lower anvil block configuration switching, so as to meet the different forgings of steam turbine steel
Procedure calls, be advantageous to improve production efficiency.
2nd, the utility model is simple in construction, it is easy to accomplish switching of the lower anvil block between various configuration.
Brief description of the drawings
Fig. 1 shows the utility model structure diagram.
Embodiment
As shown in figure 1, a kind of forging special lower anvil block of steam turbine steel, including base 1, extension plate 2, the and of anvil block monomer 3
Cushion block 4, the extension plate 2 are fixedly installed at the upper surface transverse ends extended line of base 1 respectively, the anvil block monomer 3
For two pieces, the both sides for being fixed on the longitudinal central axis line of base 1 are respectively articulated with, the cushion block 4 is movably set in the extension plate 2
On.The anvil block cell body of the base 1 and pneumatic hammer bottom-working surface coordinates, and using existing fixed structure, lower anvil block is fixed on
At pneumatic hammer bottom-working surface.The extension plate 2 is used to extend the upper surface of base 1, and the cushion block 5 is put with load.The anvil
Anvil block configuration under block monomer 3 is changed by being rotated above the base 1, so as to meet different forging technology requirements.It is described
Cushion block 4 selects pressure-resistant hard metal material, after wedging the bottom of anvil block monomer 3, by be arranged at the fin 41 of its bottom with
The groove 11 set at the upper surface of base 1 coordinates, so as to stablize the configuration angle of the anvil block monomer 3.
The end bottom of anvil block monomer 3 is provided with breach.It is easy to the insertion of the front end of cushion block 4, by the anvil block monomer 3
Load makes the anvil block monomer 3 change angle on the inclined-plane of the cushion block 4.
The abaculus 5 of triangular prism shape is provided with the base 1 between the two anvil block monomers 3.The bottom side of anvil block monomer 3
Side connects with the bottom side of abaculus 5.The bevel angle and the flank angle sum of the abaculus 5 of the cushion block 4 are 90 °, when
After the anvil block monomer 3 completes rotation, the front end of cushion block 4 connects with the fixation side of the anvil block monomer 3, the anvil block list
The side wall of body 3 is brought into close contact in the side wall of the abaculus 5, is advantageous to stable configuration.
The end of cushion block 4 is provided with push rod 6.The end of push rod 6 is provided with collet 61.Because forging temperature is higher, because
And use the push rod 6 with the collet 61 to assist operating personnel, to drive the cushion block 5 to complete corresponding operating.
Illustrate that the utility model embodiment is as follows in conjunction with the embodiments：
Round as a ball blanking：
The push rod 6 is promoted towards the direction of the base 1, drives the cushion block 4 along the extension plate 2 towards the bottom
Seat 1 slides.The front end of cushion block 4 enters the bottom of the anvil block monomer 3 from the breach, and the bottom of anvil block monomer 3 is pasted
Load is closed on the inclined-plane of the cushion block 4, the anvil block monomer 3 is rotated on the base 1.
After the fin 41 is embedded in groove 11, the stable pad of the cushion block 4 is located at the bottom of the anvil block monomer 3.
After carrying out same operation to anvil block monomer 3 described in opposite side, the two anvil block monomers 3 form anvil block under V-type, and (such as Fig. 1 center lines are right
Shown in side).Coordinate with anvil block on flat pattern, realize round as a ball blanking.
Jumping-up, shaping etc.：
After completing blanking, the push rod 6 is above carried, after the fin 41 is departed from the groove 11, by the cushion block 4 from institute
The pull-out of the bottom of anvil block monomer 3 is stated, until after the bottom of anvil block monomer 3 is bonded the base 1, anvil block under flat pattern is formed, with putting down
Anvil block coordinates in type, carries out the processing such as jumping-up, shaping.
