Abstract
The utility model provides metal plate electromagnetic forming equipment, which aims at solving the problems that the existing metal plate forming methods mostly adopt rolling processes, i.e., a rolling mill and a mold are used for implementing rolling forming on metal plates. The method belongs to contact type processing, mechanical friction marks can be easily formed on the plate surfaces, and in addition, the energy consumption is higher. The metal plate electromagnetic forming equipment has the main technical scheme that a power supply is connected in series with a coil and a loop switch after being connected in parallel with a high-voltage capacitor; metal plates and a mold with a clamp are sequentially placed under the coil, and the metal plates are fixedly arranged on the mold through the clamp. The metal plate electromagnetic forming equipment has the positive effects that the electromagnetic force is the workpiece forming motive power, and the equipment and workpieces do not have direct contact during workpiece forming, so no mechanical friction mark is formed on the surfaces of the workpieces, lubricating agents do not need to be added, and the surface quality of the workpieces is better.
Description
Technical field
The utility model relates to a kind of sheet metal former, is specifically to utilize electromagnetic force to make a kind of equipment of sheet metal moulding.
Background technology
Sheet metal moulding the current rolling mill practices that adopt of method more, use milling train and mould, at high temperature sheet metal implemented to roll forming, punch forming, shaped by fluid pressure, the method belongs to contact processing, easily plate surface is formed to mechanical scratch, and energy consumption is higher.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of sheet metal electromagnetic forming equipment that utilizes electromagnetic force.
The purpose of this utility model is achieved in that after power supply and high-voltage capacitor parallel connection, then connects with coil and circuit switching; Below coil, the direction of electromagnetic force (coil produce) places the mould of sheet metal and carrying jig successively, sheet metal by fixture be fixed on mould above.High-voltage capacitor by power supply full charge after, when circuit switching is closed, high-voltage capacitor is to coil (Microsecond grade) electric discharge fast, coil flows through electric current rapidly, and then the magnetic field changing, along with high-voltage capacitor constantly discharges, coil produces pulsed magnetic field in the direction of sheet metal, when this pulsed magnetic field passes sheet metal, sheet metal produces induced-current, and sheet metal just becomes electrical body.Sheet metal will be subject to the effect of magnetic field force in magnetic field jumpy, when this magnetic pressure reaches the intensity that makes sheet metal surrender, sheet metal is subject to the electromagnetic force of mould direction motion, and sheet metal is according to the shape generation plastic deformation of mould, i.e. moulding.
Compared with prior art, good effect of the present utility model is:
(1) electromagnetic force is the power of Workpiece shaping, during Workpiece shaping equipment with workpiece without directly contacting, so surface of the work machinery-free scratch, also, without adding lubricant, workpiece surface quality is better.
(2) because magnetic field can penetrate non-conductive material, can there is the sheet metal after nonmetallic coating or polishing to process by effects on surface, after being shaped, surface quality of workpieces is high.
(3) because sheet metal is subject to magneticaction, so sheet metal distortion is stressed, and evenly residual stress is little, and fatigue strength is high, and long service life does not affect machinery, physics, the chemical property of part after processing, do not need heat treatment yet.Electro-magnetic forming belongs to high efficiency manufacturing process, compares with routine is stamping, can effectively improve material plasticity deformability.Therefore, for the poor difficult moulding material of plasticity, be, a kind of desirable forming method.
(4) machining accuracy is high.The control of electromagnetic force is accurate, and error can be within 0.5%.During electro-magnetic forming, part is with very high speed pad pasting, and the impulsive force between part and mould is very large, and this is not only conducive to improve the pad pasting of part, and can effectively reduce part spring-go, improves significantly part forming precision.
(5) working (machining) efficiency is high, and the time is short, and cost is low, is convenient to realize the automation of producing.Adopt electromagnetic forming method can in a procedure, complete the part that just can complete with conventional manufacturing process multiple working procedure, be conducive to realize combination process.Therefore, can effectively shorten the production cycle, reduce costs.
(6) pollution-free.Electro-magnetic forming process can not produce the pollutants such as waste residue and liquid, is conducive to the protection of environment.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, further illustrate the utility model.
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
After power supply E and high-voltage capacitor C parallel connection, then connect with coil 4 and circuit switching K; Below coil, the direction of electromagnetic force (coil produce) places the mould 3 of sheet metal 2 and carrying jig 31 successively, sheet metal by fixture be fixed on mould above.High-voltage capacitor by power supply full charge after, when circuit switching is closed, high-voltage capacitor is to coil (Microsecond grade) electric discharge fast, coil flows through electric current rapidly, and then the magnetic field changing, along with high-voltage capacitor constantly discharges, coil produces pulsed magnetic field in the direction of sheet metal, when this pulsed magnetic field passes sheet metal, sheet metal produces induced-current, and sheet metal just becomes electrical body.Sheet metal will be subject to the effect of magnetic field force in magnetic field jumpy, when this magnetic pressure reaches the intensity that makes sheet metal surrender, sheet metal is subject to the electromagnetic force of mould direction motion, and sheet metal is according to the shape generation plastic deformation of mould, i.e. moulding.The 5th, auxiliary control circuit, for parameters such as the frequency in control impuls magnetic field, cycle, magnetic field intensities.The 1st, insulating part.
Claims (1)
1. a sheet metal electromagnetic forming equipment, is characterized in that: after power supply and high-voltage capacitor parallel connection, then connect with coil and circuit switching; Below coil, place successively the mould of sheet metal and carrying jig, sheet metal by fixture be fixed on mould above.
