Abstract
The utility model discloses a plane rotary type permanent magnet demagnetizer, comprising a body and a supporting plate on which a driving magnetic disc is arranged. The center of the magnetic disc is provided with a spindle which is driven by an electric motor. Permanent magnets are uniformly arranged in the casing of the magnetic disc. A working surface used for making a demagnetized workpiece be put is arranged outside the driving magnetic disc. The plane rotary type permanent magnet demagnetizer can also be provided with a driven magnetic disc besides the driving magnetic disc. A belt transfers motive power through a belt pulley or the driven magnetic disc is arranged at the corresponding position of the driving magnetic disc. The driven magnetic disc inversely rotates through the acting force of a magnetic field. The working surface is fixed or is movable. The plane rotary type permanent magnet demagnetizer adopts the rotating magnetic disc, therefore, the magnetic utilizing rate is high. The workpiece is demagnetized under the action of an axial alternating magnetic field. The effect of demagnetization is good. The utility model has the advantages of compact structure and low cost.
Description
The utility model belongs to plane rotation permanent magnetism demagnetizer.
Existing electromagnetism alternating magnetic field demagnetizer power consumption is big, about 30W-60W, and coil, iron core generate heat easily, and be fragile, and equipment is bigger, the cost height, and also demagnetization effectiveness is also not ideal.Though a kind of rotating permanent magnet demagnetizer is arranged, this demagnetizer is owing to structural reason, and its rotating permanent magnet has only 1/4 participation work, the magnet coercive force is limited, some residual magnetism requires tighter workpiece (as bearing), does not reach the GB requirement, and this demagnetizer is not suitable for relatively large workpiece demagnetization.In addition, this machine occurs workpiece easily and is pind down by magnetic field, suspends on driving-belt, skids, and has reduced the qualification rate of workpiece demagnetization, therefore, is necessary this machine is made improvements.
The purpose of this utility model provides plane rotation permanent magnetism demagnetizer, this demagnetizer tray type structure, and magnet utilance height, demagnetization effectiveness is good, compact conformation.
For achieving the above object, the utility model adopts following structure: it comprises body, support plate, dress active disk on the support plate, there is axle at the disk center, axle is by driven by motor, and uniform permanent magnet in the disk shell, active disk are equipped with outward puts the working face that the demagnetization workpiece is used.
Utilize belt pulley, belt to join a plurality of by an active disk by movable magnetic disc, its quantity depends on the needs, also can install by movable magnetic disc, follow initiatively disk revolution, not need belt pulley, belt to drive because the action of a magnetic field makes by movable magnetic disc at the correspondence position of active disk.
The utility model is described in further detail below in conjunction with accompanying drawing:

Among Fig. 2, two-sided all have a disk, and top disk is identical with Fig. 1, following disk have three corresponding by movable magnetic disc with disk in the last disk, rely on the action of a magnetic field, following disk is followed disk and is turned round.Workpiece between upper and lower disk with manual operation.Or with the horizontal installation of disk, the centre is a raceway, is used for the rolling member demagnetization.(3) be by movable magnetic disc.
Among Fig. 3, Fig. 4, (11), (12) are axle, and (10) are on-metallic protective coating, and (5) are magnet, and Fig. 5 is seen in its uniform signal, (8), (9) be main, by the movable magnetic disc shell, main, by the compression molding of movable magnetic disc useable glass steel.
Among Fig. 6, Fig. 7, (1) is the active disk, and it is driven by adjustable speed motor (23), and initiatively disk is supported on the support, and slip coattail board (19) is arranged on the support, and adjusting handle (21) drives screw mandrel (21).Nut (20), is fixedly moving on the coattail board (18) (20), and scalable is the upper-lower position of disk initiatively, and to adapt to the different needs of workpiece height, (14) are protective cover.(4) be support plate, (2) be conveyer belt, (7) are drive, and (13) are for being fixed on the card article on the conveyer belt with screw or rivet etc., with smooth demagnetization, (3) be by movable magnetic disc, it is installed on the pivoting support (15), and (15) are fixed on the pivoting support plate (16), (17) be the demagnetizer body, initiatively disk can stepless speed regulation in 600～2800 rev/mins of scopes, and the conveyer belt linear velocity is at 0.5 meter～5 meters/minute, both couplings.When drive (7) with when initiatively disk is driven, conveyer belt band workpiece (6) passes through in two planar disks of axial alternating magnetic field, to reach the purpose of demagnetization.
The utility model has the advantages that: owing to adopt tray type structure, magnet utilization rate height, workpiece is axially demagnetizing under the action of alternating magnetic field, and demagnetization effectiveness is good, this machine construction compactness, cost is low.
