Abstract
The utility model belongs to the technical field of electromechanical devices, and particularly relates to an electromagnetic demagnetizer for the demagnetization of a workpiece, especially of a bearing. The electromagnetic demagnetizer mainly solves the problems that in the traditional manual demagnetization process, a magnetic field is started and closed manually, so that the labor intensity is large, the production efficiency is low and the resource consumption is large. The electromagnetic demagnetizer comprises a power supply, a demagnetizing coil, a conveyer belt and a motor driving the conveyer belt, wherein the conveyer belt penetrates through the demagnetizing coil; an alternating-current voltage regulating device and a control device are installed between the power supply and the demagnetizing coil; and inductive switches for controlling a power switch of the demagnetizing coil are arranged at two sides of the demagnetizing coil at the moving direction of the conveyer belt. In the utility model, as the inductive switches are arranged, the work of the demagnetizing coil can be completed automatically, so that the manpower is saved, and the work efficiency is improved; and the alternating-current voltage regulating device and the control device are arranged to change the demagnetizing mode, so that the energy resource is saved.
Description
Technical field
The utility model belongs to the technical field of electromechanical equipment, specifically, relates to a kind of electromagnetism demagnetizer that is used for workpiece especially for the bearing demagnetization.
Background technology
In Production of bearing is made, when carrying out Seiko, adopt the electric magnetic no-core clamp method for processing usually, processed bearing ring is adsorbed on the jig also fixes, process again.Like this, after workpiece machines, all can have remanent magnetism because workpiece has remanent magnetism, be assembled into bearing after, bearing also will have remanent magnetism.The existence of bearing remanent magnetism will influence the quality and the life-span of bearing greatly.
At present, when bearing remanent magnetism is demagnetized, generally adopt manual demagnetizing method.After manually demagnetizing method is the demagnetizer energized, respectively each part workpiece is demagnetized, its labour intensity is big, inefficiency.Next is that traditional demagnetization mode is: big air core coil of coiling, when the transmission workpiece passes through in air core coil, the magnetic field that the demagnetizer coil produces is along with space-alternating changes, but amplitude is constant, and the decay of amplitude is to realize away from coil gradually by the displacement of workpiece on conveyer belt; In order to produce high-intensity magnetic field, must be to coil by big electric current, the power of demagnetizer is bigger, and in order to cool off heat coil, must pass to recirculated water, makes the device complexity, and resource consumption is big.
Summary of the invention
The utility model has mainly solved: in the conventional manual demagnetization, start and close magnetic field by craft, make that hand labor intensity is big, the big problem of the low and resource consumption of production efficiency provides a kind of and has started automatically in demagnetization work and demagnetizer that close, with short production cycle, energy-conservation.
The technical solution adopted in the utility model is: demagnetizer, the motor that comprises power supply, degaussion coil, conveyer belt, driving conveyer belt, conveyer belt passes from degaussion coil, AC voltage adjusting equipment and control system are installed between power supply and the degaussion coil, on the conveyer belt direction, are provided with the inductive switch of control degaussion coil mains switch in the both sides of degaussion coil.
When having workpiece to prepare by degaussion coil on the conveyer belt, the inductive switch of a side has been sensed workpiece, and degaussion coil work starts; Workpiece has moved back magnetic when leaving degaussion coil, and the inductive switch of opposite side has been sensed workpiece and left, and the degaussion coil outage is closed.Can without manual operation, reduce artificial intensity so that the operating state of degaussion coil is controlled automatically like this, enhance productivity.
AC voltage adjusting equipment and control appliance make that magnetic field constant amplitude inverse change relationship change in time is all time dependent relation of amplitude and direction, so just when having guaranteed demagnetization effectiveness and efficient, have saved the energy.
As preferably, described AC voltage adjusting equipment and control system, form by autotransformer, stepping motor, single-chip microcomputer, the input of autotransformer is connected with power supply, stepping motor connects with the rotation axis of autotransformer, the carbon brush that is connected with rotation axis respectively, and the Stepping Motor Control end is connected with the output of single-chip microcomputer.
The rotation of Single-chip Controlling stepping motor, and then can control the rotation direction of carbon brush and the slewing rate of autotransformer.
The beneficial effect that the utility model is obtained: 1) by being provided with inductive switch, make the work of degaussion coil to finish automatically, save manpower, increase work efficiency; 2) change the demagnetization mode by being provided with AC voltage adjusting equipment and control appliance, saved the energy.
