Description
Technical field
The present invention relates to numerical control open die forging base technology, more particularly to a kind of open die forging movement anti-offsetting locking machine of anvil block
Structure.
Background technology
Numerical control open die forging base is to include a set of mechanisms such as press, operation machine, mobile swage block by program coordinated signals, real
The process of existing automatic forging blank.Wherein during forging, operation chance clamping workpiece constantly rotates, and it rotates certain angle
Positioning after degree is particularly important.Refer to shown in Fig. 1, workpiece well-located state diagram when Fig. 1 is numerical control open die forging base, if
Workpiece 10 is well-located, and upper anvil 11 is with lower anvil 12 not by side force.Refer to shown in Fig. 2, work when Fig. 2 is numerical control open die forging base
Part positions the state diagram for deviation occur, if deviation occurs in the positioning of workpiece 10, even very little, now above anvil 11 can be born with lower anvil 12
Certain side force, when anvil 12 can not lock instantly, its torsional angle will be aggravated in the loading process of workpiece 10, and if lower anvil 12 is tight
Gu motionless, in the range of certain deviation occurs in the orientation angle of workpiece 10, swage block can bear cross component force, and ensure work
Part eliminates original angular deviation in deformation process.So the retaining mechanism of swage block is directly connected to blank hit position
The accuracy of stability and final molding size.
At present, the most supporting mobile swage block mechanisms of meeting of domestic numerical control open die forging shaping equipment, to meet base under different work steps
Expect the requirement of structure and size.Refer to shown in Fig. 3 and Fig. 4, Fig. 3 is facing for existing open die forging movement anvil block retaining mechanism
Figure, Fig. 4 are the upward views of existing open die forging movement anvil block retaining mechanism.Swage block 13 passes through bolt and positioning key and mobile platform
14 are connected and position, and the horizontal locking device 15 vertical with its moving direction that mobile platform 14 is set by both sides is carried out tightly
Gu but once deflection occurs or the operation machine anglec of rotation has a deviation in forging process, swage block 13 be subject to compared with
Big cross component force, cross component force is also passed to the locking device 15 of mobile platform 14 while workpiece size is influenceed.And
The coupling mechanism force of current domestic numerical control open die forging shaping equipment retaining mechanism is relatively less than normal, and secondly swage block 13 deforms and operated machine rotation
The cumulative departure of gyration is also substantially inevitable.Occur in process of production when for a long time under the above situation, mobile platform 14
Locking device 15 because deforming coupling mechanism force deficiency or locking pin and pin-and-hole locking will be caused to fail, in turn result in " mobile flat
Platform 14 locks loosely → mobile platform 14 and the stress of swage block 13 occurs offsetting → workpiece shapes deviation → and then increases cross component force
→ mobile platform 14 and swage block 13 continue stress and offsetted " as vicious circle.
The content of the invention
It is an object of the invention to provide a kind of open die forging to move the anti-offsetting retaining mechanism of anvil block, and there is mobile platform to determine for it
The characteristics of accurate reliable and service life in position is long, it is above-mentioned existing for open die forging movement anvil block retaining mechanism in the prior art to solve
Problem.
To use following technical scheme up to this purpose, the present invention：
A kind of open die forging moves the anti-offsetting retaining mechanism of anvil block, and it includes swage block, mobile platform and Equipment Foundations, the type
Anvil is fixedly connected with mobile platform by connection component, wherein, it is vertically provided with convex in the middle part of the bottom surface of the mobile platform
Platform, the positioning boss is coordinated to be mounted in offering positioning spline, the corner of the mobile platform in the Equipment Foundations
Running gear, the running gear is coordinated to offer the accommodating hole for housing running gear in the corner of the Equipment Foundations,
The lifting body for mobile platform to be lifted is provided with the accommodating hole.
Especially, the section of the positioning boss and positioning spline is to work in coordination and up big and down small isosceles trapezoid knot
Structure, to form the detent mechanism with taper.
Especially, the running gear includes the mounting bracket for being installed on mobile platform corner, is provided with the mounting bracket
Shifting roller.
Especially, the swage block is attached positioning with mobile platform by bolt and positioning key.
Especially, the lifting body uses hydraulic lifting hydraulic oil cylinder driving.
Beneficial effects of the present invention are the shifting of the open die forging movement anti-offsetting retaining mechanism of anvil block compared with prior art
Shifting roller and conical surface location structure are arranged at moving platform bottom, and Equipment Foundations are provided with lifting body.When needing to change swage block, lead to
Cross lifting body to lift mobile platform and swage block, and move horizontally and change anvil；Lifting body falls after corresponding anvil position is moved to,
The conical surface location structure for making mobile platform be made up of with Equipment Foundations positioning boss and positioning spline is accurately positioned；Forging
Cheng Zhong, conical surface location structure is set to bear equipment hitting power because mobile platform falls, the hitting power suffered by swage block is mobile platform
With the coupling mechanism force of Equipment Foundations.Lifting body can be not only protected, while because Equipment Foundations can bear larger cross component force, really
Swage block does not offset during protecting whole strike, and then extends the service life of retaining mechanism.
