Description
Technical field
The utility model belongs to forging field, and in particular to a kind of V-type anvil.
Background technology
Traditional flat-anvils stretching is pulled out by upper and lower two flat anvils, and force way is that two power, stress are bigger up and down
The crowning of forging is bigger, runs into the poor material of metal fluidity and is just unfavorable for pulling out.
From the point of view of work step is deformed, flat anvil is forged during forging deformation, and workpiece can have corner always（It is i.e. polygon
Angle）, and the temperature drop in corner is always bigger.Whole workpiece is always and cooled during the ceaselessly side of walking, and causes work
Part temperature the more is beaten the more low.For workpiece corner temperature already below the temperature range of dynamic recrystallization, this often produces grain size not
Uniformly, crystal grain varies.
It is in existing forging technology again, because forging impulsive force is big, difficult positioning between upper and lower anvil, easily misplaces or sliding
Move, forging stability is poor, and finished size precision is not high, and condition is poor, and controllability is low.
Utility model content
The purpose of this utility model is to provide the V-type anvil that a kind of stability is good, controllability is strong to solve the above problems.
Above-mentioned technical purpose of the present utility model technical scheme is that：
A kind of V-type anvil, including upper anvil, the top that is embedded on pedestal have the lower anvil of V-groove, in addition to base, described
Pedestal is by the way that located at the dovetail auxiliary section of bottom, on the base, the pedestal is provided with the embedding of front and rear insertion and open top
Groove, integrally connected is vertically provided with positioning bar on the cell wall of caulking groove both sides, and the lower anvil both sides correspond to the positioning bar and offer positioning
Groove, the lower anvil bottom are installed with the one layer of cast iron bed course that repairs a die.
The material of V-type anvil is generally preferable steel, and such as H13 or 5CrNiMo, its cost is high, and the application is used under
Anvil bottom sets the mode for the cast iron bed course that repairs a die, when save anvil with material amount, it is special when having saved cost, while having needed to repair a die
It is not the bed course of bottom of can directly being polished when adjusting in the height direction, the waste of preferable steel will not be both caused, in anvil rank processed
Section can make relatively low lower anvil, beneficial to the saving of cost.And bottom cushion uses cast iron, repair a die also more convenient.
Preferably, the upper anvil is flat board anvil or the V-type with inverted V-groove corresponding with the V-groove on lower anvil
Upper anvil.
The pulling of V-type anvil is forged using upper flat lower V frame mode, and its force way is three-dimensional compressive stress, by
The pressurization of three points, forging both sides crowning is smaller, and extension is very fast so drawing efficiency is higher.Pass through the angle to V-type anvil
Modification, drawing efficiency highest is that angle is 90 degree.
V-type anvil is that of avoiding the excessive corner cooling that workpiece occurs in forging process from the point of view of work step is deformed.Forged
Workpiece is reduced temperature drop during dynamic deformation by ceaselessly rotating in journey, excite inside workpiece forging heat to make up work
The temperature drop on part surface, stress is also than more uniform, so that tissue obtains uniform grain size.
Preferably, being provided with guide block post positioned at the both sides of caulking groove at the top of the pedestal, led described in the upper anvil both sides correspondence
Block post offers guide groove, and the guide block column top is provided with buffer spring.
It is preferably, open on the outside of the guide groove.
The guide block post of said structure and the setting of guide groove, its structure is larger, guide block post and pedestal integrally connected and account for width
Degree account for more than 2/3 width at the top of base degree, and guide block post leads that power is big, and anti-impact force and twisting resistance are strong, and lower anvil consolidates.Using
Shi Gangcai is disposed on compressing anvil on lower anvil, coordinates the lower anvil structure with pedestal integrally connected, so that upper anvil is as far as possible
Elaborate position is led in ground with guide block post, and complete equipment is not easy to shift or damaged.And the set-up mode that guide groove outside is open, it is easy to
Observation also allows for the socket of guide block post and guide groove, while reduces the requirement of machining accuracy.
Preferably, offer the inward oriented hole of open top on the guide block post, being installed with the guide groove can be along interior
The guide pillar that guide pillar hole slides up and down, the outside that the guide block column top is located at the guide pillar can for being embedded provided with outside opening
The quantitative caulking groove of the quantitative pad of quantitatively upper spacing nearest between anvil and lower anvil, first piece of quantitative pad being embedded in quantitative caulking groove
Piece is highly higher than the quantitative caulking groove height.
Minimum distance between upper and lower anvil determines the specification of finished steel, can be adjusted by the setting of quantitative pad
Minimum distance between lower anvil, that is, limit the degree that guide groove pushes.The setting of quantitative caulking groove is easy to that pad need not be being quantified
When guide groove can the top of fully gland to guide block post be that groove top connects capital.It is high that first piece of quantitative spacer height is higher than quantitative caulking groove
Degree realizes first piece of quantitative pad i.e. adjustable speed minimum distance when needing to adjust the minimum distance between anvil up and down, it is not necessary to
Add two pieces.Certainly, require that specification is different according to steel, the quantitative pad of stackable polylith.
Preferably, the upper anvil include top base and be embedded at from the bottom to top top base bottom and have with lower anvil
The upper anvil block of inverted V-groove corresponding to V-groove, the upper anvil block is inserted in by level between the upper anvil block and top base
The positioning strip that both sides between top base are connected on cell wall is fixedly connected.
Preferably, triangular groove is correspondingly offered between the upper anvil block and the both sides joint face of top base, and upper anvil block
Corresponding triangular groove fills the span of a man's arms to form square slotted eye with top base, the positioning strip be inserted in it is in the square slotted eye and
It is topmost the corresponding upper anvil block and the square bar of the rib of the splicing seams of top base.
The frame mode of above-mentioned side's bar and square groove is the fixation for being easy to upper anvil, is easy to the adjustment of upper anvil again, while also have
There is preferable shock resistance buffer capacity, upper anvil is hardly damaged, and the stress of square bar is on the inclined-plane of both sides, and impulsive force is small, not rapid wear
It is bad.
Preferably, side's bar includes bearing against generous bar in seam on the square slotted eye and lower seam and small
Square bar, small side's bar book is in the generous bar.
Generous bar is first inserted in slotted eye, then in the suitably small side's bar insertion slotted eye of reselection, the setting drop of large and small side's bar
The low required precision of other side's bar, is conveniently adjusted and assembles.
It is symmetrically welded preferably, the lower anvil includes two pieces of edges using the gravity face at the axially place of V-groove as the plane of symmetry
Half anvil block.
For the lower anvil of some larger shapes, it is desirable to mould it is big, processing trouble, can by the way of above-mentioned half anvil block
Reduce difficulty, save processing cost.
Preferably, be inserted with positioning splicing bar on the face of weld between the half anvil block, the positioning splicing bar and two
The half anvil block welding is fixed.
Positioning splicing bar is easy to the positioning docking of two and half anvil blocks.
In summary, the utility model has the advantages that：
