Forming property is poor at normal temperature for gold, magnesium alloy and titanium alloy etc., and elasticity modulus is small, and Forming Workpiece is easy to appear crackle and rebound
The defects of.Research shows that high-rate forming can effectively improve the forming property of light alloy at room temperature, most as current research
For one of extensive high-rate forming technology, electromagnetic forming technique has been widely used in the manufacture fields such as plate, pipe fitting.
During electro-magnetic forming, the electric current changed in coil can induce contrary electric current, the two phase in plate
Interaction, which generates, repels Lorentz force, and high-speed deformation occurs for workpiece under the action of Lorentz force.By taking plate shapes as an example, electromagnetism
FAQs is as follows in forming process: (1) repeatedly in manufacturing process, plate regional area is not bonded with mold, and at this time these
Farther out, the electromagnetic force that coil discharge generates is not enough to improve the mold in these regions to distance between region and coil, leads to plate
Part forming accuracy is poor.In order to solve this problem, it has been disclosed that patent CN107186039A propose coil outer different zones increase

Rebound wrinkling, influence the dimensional accuracy of workpiece.To two kinds of problems later, using the method for collection chinaware carry out part at
Shape can attend to one thing and lose sight of another, and be unable to improve the dimensional accuracy of workpiece.
Current most electro-magnetic forming is no mould free forming, and plate deforms no sized boundary constraint, causes to shape
Precision is low.Even there is contour forming, under high-speed deformation, plate collides with mold can generate rebound, this makes Forming Workpiece
With good mold degree so that it is also very difficult for reaching higher dimensional accuracy.In addition, (original blank small for radius-thickness ratio
Thickness and the ratio of diameter be usually less than for 3 workpiece ‰), corrugation is easy to happen in forming process or part corrugation is lost
Effect, this reduces the dimensional accuracies of Forming Workpiece.In electro-magnetic forming, it is limited by the limit of structure size between coil and mold
System, what coil position was usually fixed, naturally it is also possible to coil dimension is reduced, according to the deformation extent regulating winding position of plate
It sets, but the force distribution of coil is uneven, so often attending to one thing and lose sight of another when forming, Forming Workpiece precision is difficult to improve.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
The utility model provides a kind of electromagnetism orthopedic appliance and straightening method, and structure is simple, orthopedic effect is good, can be with
Forming Workpiece dimensional accuracy is low during solution electro-magnetic forming and is difficult to the technical issues of improving.
The utility model provides a kind of electromagnetism orthopedic appliance, comprising: power-supply system 1, driving coil 2 divide chinaware 3, pressure
Flange 4 and mold 6, wherein mold 6 is set in the plane, for constraining the deformed region of workpiece, improves the size essence of Forming Workpiece
Degree；Evacuation passageway is provided in the middle part of mold 6, channel both ends are connected with mold cavity and vaccum-pumping equipment respectively, for excluding mould
The intracavitary air of tool type, reduces or even eliminates the air drag in plate deformation process；Blank holder 4 is placed in orthopedic plate 5
Above flange region, pressure-pad-force is provided for flange region during electro-magnetic forming for plate, specifically, in formation
Main function is, by adjusting amount of flow of the kiss gating-feeder plate flange region material into mold cavity.Driving coil 2 can

Vortex is induced, and by dividing chinaware that this vortex is transmitted to plate surface on the surface of corresponding point of chinaware, wait rectify
Vortex is induced on shape plate, generation Lorentz force realization is orthopedic, improves the dimensional accuracy of plate.
For power-supply system 1, capacitor energy storage type power-supply system can be used, electric current be based on RLC circuit and more
Obtained by physic field coupling, specific waveform is as shown in Figure 7.
In the utility model, the orthopedic dimensional accuracy for improving workpiece, it is real for dividing the shape of chinaware identical as mold profile
Existing orthopedic specific means, basic goal is to make plate and mold mold, and mold is designed according to the requirement of specific workpiece,
Therefore good mold degree just can guarantee that workpiece has good dimensional accuracy.
In the utility model embodiment, for and use plate spiral winding orthopedic by double of elliposoidal housing component, line
When circle electric discharge, the upper plane of corresponding with coil point of chinaware takes the lead in inducing vortex, because chinaware is divided to be provided with gap, has blocked whirlpool
The circulation in upper plane is flowed, so vortex can be passed on N-Side surf, since the area of N-Side surf is greater than the area of upper plane,
So surface current density reduces in transmittance process, Gu this process becomes dispersion transmitting, transfer medium is known as a point chinaware.
