Description
Technical field
The utility model relates to the automatic wet press of magnetic material, the quantitative material feeding control device of particularly a kind of magnetic material wet pressing.
Background technology
Ferrimagnet has been widely used in various uses, comprises equipment for example motor, motor etc. with rotor.Ferrimagnet has wetpressing and dry pressing in making moulding, wherein the ferrimagnet of wetpressing moulding fills in the demagnetization process in compacting, and the arrangement of particulate is more orderly, makes its performance be better than the ferrite of dry pressing.Existing wetpressing is at the flat 2-98106A of Japan Patent JP, and JP-A-2-98106 describes in Chinese patent 200610035698.6 patent documentations such as grade to some extent.
Above-mentioned wetpressing normally carries out press process in the ferrite magnetic material wet press.Starting materials for ferrites is that a kind of water content is about 32～38% slurry injecting (conveying) to the wet press mould, and the consistent in density of green compact compression moulding has direct relation with the amount of the slurry that injects mould.The shot of existing ferrite magnetic material wet press is controlled by oil cylinder stroke, and error is bigger; And can not effectively prevent the feed back phenomenon during material feeding, change greatly to the shot that makes each mould, cause the density error of each mould green compact bigger, thereby the green sintering distortion is big, make the mill allowance of back operation uncontrollable, waste of raw materials is bigger, can't directly utilize high efficiency four station through type grinding machines to carry out back processing.
The utility model content
The purpose of this utility model is: at the deficiencies in the prior art, provide a kind of device that can realize the quantitative material feeding control of wet press, realize not feed back of quantitative material feeding and material feeding, to reach the uniformity of control magnet green density.
The technical solution of the utility model is: the utility model comprises the material feeding oil cylinder, control circuit, and feeding materials valve, injecting device, jockey also comprises the stopping means by control circuit control; Described stopping means is connected with injecting device by jockey.Described control circuit is connected with cyclelog, the amount of control stopping means displacement, and the amount that reaches control injecting device material feeding or suction realizes quantitative material feeding.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are: the amount that material feeding is set by the control of stopping means follow procedure to the size of the amount of mould is carried out, and realizes quantitative material feeding or suction control.This plays crucial effect for the uniformity that guarantees the magnetic material green density, can reduce the sintering warpage of operation behind the green compact, for processing and utilization high efficiency four station through type grinding machines in back have been created condition, can reach and enhance productivity, can reduce simultaneously the mill allowance of back operation, improve utilization rate of raw materials, reduce manufacturing cost.

Working method of the present utility model is as follows:
1. the displacement control material feeding of stopping means 1 follow procedure controller setting or the amount of suction realize quantitative material feeding;
2. after the compression moulding of magnet blank, cyclelog compares moulding magnet blank thickness and setting thickness automatically, when the magnet blank thickness surpasses the tolerance that allows, illustrates that variation has taken place the amount of material feeding;
3. this moment, cyclelog will be controlled the displacement of stopping means 1, adjusted the amount of control material feeding or suction;
4. after adjustment reached and stablizes, cyclelog control stopping means kept the amount of material feeding or suction constant, realizes quantitative material feeding.
Described stopping means 1 can be by motor-driven jockey 7, and its control circuit is connected with cyclelog, and the amount of control connection device displacement realizes quantitative material feeding.
Described stopping means 1 can be grating chi, electronic ruler or the similarly quantitative material feeding of straight-line displacement measurement mechanism control realization.
The above only is preferred embodiment of the present utility model, not in order to restriction the utility model, all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
