METHOD AND SYSTEM FOR USING INDUCTION HEATING TO SHAPE OBJECTS
20210346932 · 2021-11-11 ·

A method and system are provided for using induction heating to shape a work piece panel into a preselected shape. The method includes positioning a work piece panel near or in abutment with at least a first induction coil. Alternating current (AC) having a preselected amplitude and frequency can be passed through at least the first induction coil while the work piece panel is subjected to at least one preselected shaping condition. An alternating electromagnetic field produced by the AC current, can cause eddy current in the work piece panel that can heat it to a preselected temperature for a preselected period of time while subjected to the preselected shaping condition, thereby causing the work piece panel to attain the preselected shape. The alternating electromagnetic field can also create a repelling electromagnetic force between the coil and the work piece panel, which could be a shaping condition.

Stepped pipe member and stepped pipe member production method

Formed in series along an axial-direction end portion of a large-diameter pipe member, in the following order from the pipe end, are: a large-diameter-pipe pipe-end expanding portion; a large-diameter-pipe reduced-diameter portion; a large-diameter-pipe bulging portion; and a tapered portion. Formed in series along an axial-direction end portion of a small-diameter-pipe member, in the following order from the pipe end, are: a small-diameter-pipe pipe-end expanding portion; a small-diameter-pipe enlarged-diameter portion; and a small-diameter-pipe bulging portion. The outer cylindrical surface of the small-diameter-pipe enlarged-diameter portion is in close contact with the inner circumferential surface of the large-diameter-pipe reduced-diameter portion; the inner cylindrical surface of the large-diameter-pipe bulging portion and the outer circumferential surface of the small-diameter-pipe pipe-end expanding portion are engaged; and the inner circumferential surface of the large-diameter-pipe pipe-end expanding portion and the outer cylindrical surface of the small-diameter-pipe bulging portion are engaged.

Electromagnetic manufacturing method and forming device of mesoscale plate

Electromagnetic manufacturing method and forming device of mesoscale plate are provided. The manufacturing method includes: oppositely and parallelly disposing a first workpiece to be formed on top of a mold, side-press restraining two ends of the first workpiece, and disposing a deceleration block on two sides of the mold; controlling the first workpiece to tend toward the mold and to be deformed under the drive of uniform electromagnetic force; and colliding a middle area of the first workpiece firstly with the mold under the drive of uniform electromagnetic force, and driving the speed of the middle area of the first workpiece to decelerate to zero.
