Electromagnetic orthopedic device and orthopedic method

Abstract

The invention discloses an electromagnetic orthopedic device and an orthopedic method, belonging to the technical field of metal forming manufacturing, comprising a uniform pressure drive coil, a magnetic field shaper, a conductive channel and a mold; the uniform pressure drive coil is arranged inside the conductive channel; the conductive channel and the The orthopedic workpiece forms a conductive circuit; the magnetic field shaper is arranged between the uniform pressure drive coil and the workpiece to be orthoped; the uniform pressure drive coil generates a pulsed magnetic field around it through pulse current discharge, and the pulsed magnetic field generates an induced eddy current on the surface of the magnetic field shaper; the magnetic field The shaper cooperates with the uniform pressure driving coil to generate an induced current in the conductive circuit, and the induced current generates a pulse electromagnetic force on the area to be shaped of the workpiece to be corrected; the area to be formed of the workpiece to be corrected is deformed to the mold under the action of the pulse electromagnetic force. The invention can flexibly and accurately control the orthopedic or multiple forming processes of the workpiece through the optimized design of the magnetic field shaper, effectively reducing the design difficulty and manufacturing cost of the forming device.

Technical field [0001] The present invention belongs to the field of metal forming manufacturing, and more particularly to an electromagnetic orthopedic device and an orthopedic method. Background technique [0002] Lightweight alloy materials provide effective implementation of industrial production of automobiles, aerospace and other fields. Meanwhile Studies have shown that high-speed forming can effectively improve the formation performance of light alloy at normal temperature. Therefore, electromagnetic forming techniques have been widely used in the field of processing of light alloy materials such as aluminum alloys. [0003] In the electromagnetic forming technique of non-axisymmetric panels, the use of a homogeneous driving coil is a functional method. In the electromagnetic forming of the panel, there is a common problem: (1) In the primary forming method, the panel may cause a certain error of the panel size and the mold size due to the bulk of the discharge energy or ...

Problems solved by technology

In the electromagnetic forming of the plate, there are the following common problems: (1) In the one-time forming method, the plate may have a certain error between the size of the plate and the mold size due to insufficient discharge energy or the rebound of the material, or it may be caused by the discharge Excessive energy leads to local wrinkling due to the collision between the plate and the mold; (2) In the multiple incremental forming method, the part of the plate has not yet been attached to the mold after the initial forming, and the distance between the local area of ​​the plate and the coil during subsequent forming If it is stretched, the magnetic field intensity generated during the forming process will be significantly reduced, resulting in insufficient electromagnetic force required for forming, which will affect the forming accuracy of the sheet; The required forming process (such as the forming of local complex features) is difficult

For the above problems, the method of using a special shape to drive the coil will increase the difficulty of coil design, resulting in increased manufacturing costs, poor flexibility, and a single application range of the coil.
