Abstract
Disclosed is a mixed permanent magnetic-electromagnetic force device, which is composed of a permanent magnetic system 17, an electromagnetic force system 18 and an isolation layer 5 disposed between the two systems. The utility model stacks or subtracts the constant permanent magnetic force and the electromagnetic force by changing the magnetic field direction and size of the electromagnetic force system, thus achieving the purposes of magnetic intensity control and demagnetization. Besides, the utility model is also provided with an electromagnetic force application system for increasing the magnetic force to a super strong level. When the emergency of circuit fault or power failure takes place, the permanent magnetic system will play a role in fixing the magnetic force independently. The utility model is applied to plastic injection machines, oil pressure clapper die spotting presses and magnet cranes with extremely high safety requirements.
Description
The utility model relates to a kind of permanent magnetism-electromagnetism hybrid magnetic power apparatus.Be used for machine industry as location and fixing magnetic force instrument.
Traditional permanent magnetic device all adopts the mode of machinery dislocation or rotary magnetic steel to reach the purpose that magnetizes, demagnetizes, and its shortcoming is:
1. the excessive or suspicion of inconvenient operation of magnetization, demagnetization operating physical force is arranged for large-scale permanent magnetic device.
2. be difficult to far distance controlled.
3. permanent magnetism disk card bearing capacity is poor usually, when disk is used for the bigger various press of pressure-bearing, the disk panel deformation might occur, has influence on the activity of magnet steel, and the operation of magnetization, demagnetization can't be carried out.
The utility model adopts fixedly the U-shaped permanent magnetism magnetic source magnetic circuit system and the U-shaped electromagnetism magnetic source magnetic circuit system composition hybrid magnetic device of magnet steel group.Direction and size by the conversion exciting curent realize the stack of magnetic force or the purpose of counteracting.
The utility model is achieved by the following technical solution: permanent magnetism-electromagnetism mixed type power apparatus has permanent magnetic circuit system and electromagnetic circuit system.Permanent magnet system by irreversible pole-changing to Nd-Fe-B magnet steel, form every magnetic copper coin (or stainless steel) and No. 10 steel magnetic conductive boards.Magnet steel is embedded in the magnetic copper coin, and is clipped between the magnetic conductive board of both sides, can form a constant permanent magnetic field.The electromagnetism magnetic system is by magnetizing coil, and iron core and magnet frame frame are formed.Be provided with the magnetic separator between two systems.This separator allows the magnetic line of force of electromagnetism magnetic system to pass through, and the magnetic line of force of permanent magnetic system system be difficult to by.Produce by the electromagnetism magnetic system with the identical or opposite magnetic line of force of permanent magnetic system system magnetic direction, reach the stack of two system's magnetic lines of force or subdue.When the electromagnetism magnetic system breaks down or cuts off the power supply, the permanent-magnet system will play the fixing effect of magnetic force separately.
The utility model has big, the good rigidly, safe and reliable of magnetic force compared with traditional magnetic means, remarkable advantage that can straighforward operation.
