Background technology
In the industrial production, many work pieces process adopt magnechuck absorption workpiece mode, and after completion of processing, need to eliminate magnetic again, ensure machining accuracy and the Detection job of product.But, for the multi items, different produced in enormous quantities, the demagnetization of the workpiece that size difference is large, just need one can be compatible strong to workpiece size, be suitable for the demagnetizer of multi items specification, reach the object of batch workpiece demagnetization.
At present, can meet the demagnetizer of above-mentioned this situation, what usually adopt is permanent magnetism demagnetizer.This
The feature of demagnetizer is, its inside is permanent magnet.Transport tape is respectively had one group of such demagnetizer by the workpiece that demagnetizes is upper and lower, and by motor band, it rotates, and the NS pole alternately change of permanent magnet, produces alternating magnetic field.
This demagnetization mode there are certain requirements workpiece size height, need according to different workpiece height, regulate the screw rod that demagnetizer moves up and down, it is made to select suitable height as far as possible, reach demagnetization effectiveness, for a lot of enterprise, when having every day the workpiece of multiple kind to need to demagnetize, repeatedly will adjust the height of which group demagnetizer of top, operation seems more loaded down with trivial details.This demagnetization mode has a problem to be difficult to avoid, during demagnetization work, when a collection of workpiece is when passing through permanent magnet demagnetizer with transport tape, above which is organized permanent demagnetizer and there will be the phenomenon of absorption by workpiece, by absorption of workpieces on the shell of a group permanent-magnet demagnetizer above, depart from transport tape.Under the NS pole rotational transform rotated, this workpiece is ceaselessly shaken on this demagnetizer shell, below this part shake workpiece, transport tape is ceaselessly passing through with the workpiece that demagnetized in batch, some workpiece will be subject to the collision of upper and lower shake workpiece, and workpiece can scratch, and chamfering can bump injury.
Summary of the invention
The object of the invention is the deficiency for solving the problems of the technologies described above, a kind of many magnetic poles group integration through type demagnetizer being provided, not only can effectively preventing workpiece from scratching, the bump injury of chamfering, the dimensional requirement of dissimilar workpiece demagnetization can also be met.
The present invention is for solving the problems of the technologies described above, the technical scheme provided is: a kind of many magnetic poles group integration through type demagnetizer, comprise belt conveyor, multiple demagnetization assembly and the fagging for supporting demagnetization assembly, described fagging is fixedly installed on below the conveyer belt of belt conveyor, multiple demagnetization assembly is along the throughput direction spread configuration of conveyer belt, described demagnetization assembly comprises the housing of upper end open, can the cover plate of closure casing, the coil windings being placed in the iron core group in housing and matching with iron core group, the upper surface of cover plate contacts for support belt with conveyer belt, iron core group is made up of bottom disk and multiple iron core column be arranged on the disk of bottom, each iron core column is all arranged with coil windings, all coils winding all accesses demagnetization circuit.
Further improvement as a kind of many magnetic poles of the present invention group integration through type demagnetizer: the cover plate of described demagnetization assembly is anti abrasive non-magnetic material.
Further improvement as a kind of many magnetic poles of the present invention group integration through type demagnetizer: the distance on described fagging between adjacent two demagnetization assemblies is all identical.
Further improvement as a kind of many magnetic poles of the present invention group integration through type demagnetizer: in described iron core group, multiple iron core column is disposed side by side on the disk of bottom.
Further improvement as a kind of many magnetic poles of the present invention group integration through type demagnetizer: the orientation of described multiple iron core column and the throughput direction of conveyer belt arranged in parallel.
beneficial effect
1, through type demagnetizer structure of the present invention is simple, combination by means of only iron core group and coil windings produces magnetic field, device is failure rate is low in running, and workpiece is in demagnetization process, field regions can be smoothly passed, the scuffing and the chamfering that avoid part are damaged, and the percent defective of demagnetization workpiece is reduced greatly;
2, through type demagnetizer of the present invention overlaps a coil windings in each iron core column, therefore the field homogeneity of operationally iron core group end face, magnetic field intensity is large, by demagnetization workpiece by the process of alternating magnetic field, eliminate magnetic, after demagnetization, workpiece residual magnetism amount is little;
3, through type demagnetizer of the present invention can meet the dimensional requirement of dissimilar workpiece demagnetization, according to the size treating demagnetization workpiece, selectivity increases or reduces the quantity of assembly that fagging demagnetizes, and does not need the transporting velocity reducing conveyer belt, and then can not reduce operating efficiency.
