1 hoisting electric control permanent magnet principle and structure
Hoisting electric control permanent magnet is to convert the permanent magnetic circuit system through the current pulse is very short, so as to realize the workpiece holding and releasing a new hoisting equipment. The disk body is processed by the high quality low carbon steel CNC block formed, sealing with epoxy resin, the structure stable, strong, high precision, to ensure durable, reliable and insulation disk. The magnetic core with high performance rare earth permanent magnet manufacturing, magnetic pole arrangement in a checkerboard fashion at the disk surface, so that the magnetic field lines in the horizontal plane and cross flow on the workpiece generates a uniform and efficient suction force. The power only in the fixed and release process of the workpiece in the magnetization and demagnetization stage is short use, therefore in the workpiece hoisting process, the workpiece is only produced by high-energy permanent magnetic rare earth magnets to fixed, magnetic without power failure effect, product safety is good.
2 hoisting electric control permanent magnet productsTechnical characteristics of
2.1 hoisting electric control permanent magnet sucking force strong, safe and reliable; the clamping surface to maintain a "cold 'state, no deformation and swelling, the physical stability of workpiece holding good, safe and reliable.
2.2 hoisting electric control permanent magnet lifting workpiece positioning fast and flexible, since only the use of transient current, more electromagnetic sucking disc 95% energy saving, has the characteristics of safe and energy-saving.
2.3 hoisting electric control permanent magnet and Permanent Magnet Lifter need to manually rotate wrench for magnetizing and demagnetizing operation, high labor intensity compared to hoisting electric control permanent magnet can realize filling demagnetization, button operation can be power supply controller has the advantages of simple operation, convenient use, but also to facilitate remote or automatic control advantages.
2.4 hoisting electric control permanent magnet and lifting electromagnet work need to continuously maintain power,high power consumption, and in case of an external power-off or coil system fault, the electromagnet magnetic losscaused by workpiece drop accidents often occur, use safety is low compared to heavy electric control permanent magnet has the advantages of safety accidents more than 95% energy saving, can exclusion caused by power cutand the line fault.
3 hoisting electric control permanent magnet productsApplication of
Hoisting electric control permanent magnet because of its have the prominent characteristics, has been inshipbuilding, steel structure welding plant, factory, warehouse, workshop, freight yard and all kinds of liftingequipment for use in holding plate ferromagnetic material or workpiece can single use, can also be multiple workpiecein ferromagnetic materials suction big and long. In the yard, steel pretreatment production line, plate cutting line and other occasions instead of the lifting magnet steel. The product has a compact structure, convenient operation,suction to strength strong, low power consumption and safe and reliable, and is helpful to improve the handling of theworking conditions, improve the labor productivity. As a kind of efficient, safe, energy-saving model hoisting equipment, has been widely used in shipbuilding, engineering machinery, mold manufacturing industry.
4 Function and use method this product
4.1 the product function
The hoisting electric control permanent magnet system is mainly used for ordinary carbon steel plate in the form of lifting and handling, and the plate material stacking lift single sheet. The practical application with double beam and double gourd gourd driving, each supporting a 2T crane electric control permanent magnet.
The system has the following main function can:
A. hoisting electric control permanent magnet power supply special control box switch.
B. double key interlock control of magnetization and demagnetization, safe and reliable.
C. The controller is arranged warning lamp, instant indicating working state.
D. of the system is divided into strong and weak magnetization magnetization magnetization of two stalls, weak magnetizing strength according to the thickness of the workpiece 16 level linear adjustable, ensure every lifting a piece of steel plate.
E. after the lifting of the system automatically to the workpiece a strong magnetizing, strengthening of the workpiece holding.
F. of each disk configuration gating switch, can control alone.
G. the hoisting electric control permanent magnet system operation can be realized by remote control.

5 This product use matters needing attention
5.1 hoisting electric control permanent magnet must use, overloading is strictly prohibited in the rated lifting weight range, to prevent accidents.
5.2 in the process of lifting hoisting electric control permanent magnet, is strictly prohibited in the personnel and equipment through the sky.
5.3 The should always keep the hoisting electric control permanent magnet clean and smooth surface. In the transport and use process, should prevent knocking, bumps, so as not to affect the performance of.
5.4 lifting workpiece is big and long, should put the hoisting electric control permanent magnet is placed in the position of the center of gravity is absorbing materials. Note that a single hoisting electric control permanent magnet lifting workpiece length not greater than 3000mm; multiple hoisting electric control permanent magnet combination is hanging, two sets of hoisting electric control permanent magnet spacing also not more than 2500mm.
5.5 hoisting electric control permanent magnet must conduct a calibration every year since the day time use, to ensure safety.
5.6 hoisting electric control permanent magnet operation should strictly carry out operation regulations state hoisting apparatus.
