Description

II

Изобретение относитс  к машиностроению и может быть использовано при магнитно-абразивном полировании листового материала, лент, а также деталей типа цилиндров, конусов, обечаек и т.п.The invention relates to mechanical engineering and can be used in the magnetic-abrasive polishing of sheet material, belts, as well as parts such as cylinders, cones, shells, etc.

Известен способ магнитно-абразивной обработки, при котором деталь помещают между полюсами электромагнитов , расположенных с зазорами над деталью и под ней, причем рабочий зазор между деталью и полюсом верхнего электромагнита заполн ют магнитно-абразивным порошком, а детали и электромагнитам сообщают рабочие движени  Dl .A known method of magnetic abrasive treatment, in which a part is placed between the poles of electromagnets arranged with gaps above and below the part, the working gap between the part and the pole of the upper electromagnet is filled with a magnetic abrasive powder, and the parts and electromagnets are reported by workers movements Dl.

Однако при таком способе обработки значительна  часть энергии магнитного пол  тер етс  на преодрлении нерабочего воздушного зазора между полюсом нижнего электромагнита и обрабатываемой деталью, что ведет к уменьшению сил резани , которые завис т от величи)1Ы магнитной индукции в рабочем зазоре, а следовательно , приводит к уменьшению производительности обработки.However, with this method of processing, a significant part of the magnetic field energy is lost in overcoming the inoperative air gap between the pole of the lower electromagnet and the workpiece, which leads to a decrease in cutting forces that depend on the magnitude of magnetic induction in the working gap, and therefore leads to reduced processing performance.

Целью изобретени   вл етс  повышение производительности обработки.The aim of the invention is to improve processing performance.

Поставленна  цель достигаетс  тем, что согласно способу нерабочий зазор заполн ют порошком м гкого железа .This goal is achieved in that according to the method, the non-working gap is filled with soft iron powder.

На чертеже представлено устройство дл  реализации предлагаемого способа .The drawing shows a device for implementing the proposed method.

Устройство содержит верхний электромагнит- I с П-образным сердечником и аналогичный ему нижний электрона нит 2, между которыми располо сена деталь 3.The device contains an upper electromagnet I with a U-shaped core and a similar electron lower nit 2 between them, between which the part 3 is located.

Обрабатываема  деталь 3 перемещаетс  возвратно-поступательно между соосно расположенными cepдeчникa fи электромагнитов 1 и 2. Верхний электромагнит I установлен с технологически необходимым зазором, заполненным магнитно-абразивным порошком.The workpiece 3 is moved reciprocally between coaxially located cores f and electromagnets 1 and 2. The upper electromagnet I is installed with a technologically necessary gap filled with magnetic abrasive powder.

,Нижний электромагнит 2, ycтaнoвлeнный с минимальным относительно детали зазором d , заполненным порошком магнитом гкого железа 4, вращаетс  принудительно и за счет заполнени  нерабочего зазора порошком магнитом гкого железа, имеющего магнитную проницаемость-в 3-4 раза вьш1е магнитной проницаемости воздуха, ведет к уменьшению потерь магнитного потока и увеличению сил резани , а следовательно, увеличению производительности обработки в 1,5-2 раза.The lower electromagnet 2, installed with a minimum clearance of d, filled with a powder of soft iron 4, is forced to rotate and by filling the non-working gap with a powder of a soft iron magnet having a magnetic permeability of air that leads to a decrease in the non-working gap loss of magnetic flux and an increase in cutting forces, and, consequently, an increase in processing productivity by 1.5-2 times.
