Description
Из авт. св. № 64508 известно устройство дл нагрева изделий под закалку по способу Лагранжа и Хого.From auth. St. No. 64508, a device for heating products for quenching according to the method of Lagrange and Hogo is known.
В этом устройстве под или над зажимами, в которых укрепл ют изделие, погружаемое в ванну с электролитом, расположен валик, несущий поворотные упоры дл торцов деталей.In this device, under or above the clips, in which the product is immersed, immersed in an electrolyte bath, there is a roller that carries pivoting stops for the ends of the parts.
Благодар указанным унорам фиксируетс глуби1 а погружени изделий в электролит, а следовательно, размеры нагреваемого участка издели , и сохран етс посто нным температурный режим в случае выполнени обработки одинаковых изделий.Due to these unores, the depth of immersion of the products in the electrolyte is fixed, and consequently, the dimensions of the heated area of the product, and the temperature is kept constant in the case of processing the same products.
Насто щее изобретение вл етс развитием изобретени по авт. св. № 64508 и заключаетс в том, что упоры дл торпов обрабатываемых изделий выполнены из огнеупорного изол ционного материала, с целью предохранени торцов обрабатываемых изделий от оплавлени .The present invention is a development of the invention by the author. St. No. 64508 and the fact that the stops for the torps of the processed products are made of refractory insulating material, in order to protect the ends of the processed products from melting.
На чертеже изобрал ;ена схема расноложени упора и нагреваемого издели в ванне с электролитом.The drawing shows a diagram of the disposition of the abutment and the heated article in an electrolyte bath.
В жидкий электролит, на который нодаетс напр жение от положительного полюса источника посто нного тока, помещают на строго определенную глубину упор, изготовленный из огнеупорного изол ционного материала, выполненный, например, в виде фарфоровой плитки /, вкладываемой в оправку 2.In the liquid electrolyte, on which voltage is applied from the positive pole of the DC source, an emphasis made of a refractory insulating material, made, for example, in the form of porcelain tile /, inserted into the mandrel 2 is placed at a strictly defined depth.
Нагреваемое изделие 3, соединенное через зажим 4 с отрицательным полюсом источника посто нного тока своим торцом упираетс в упор /, благодар чему торец издели 3 предохран етс от нагрева и оплавлени .The heated product 3, connected through the clamp 4 to the negative pole of the direct current source, abuts against the end / with its end face, due to which the end face of the product 3 is protected from heating and melting.
Предмет изобретени Subject invention
Форма выполнени устройства по авт. св. № 64508, отличающа с тем, что уноры дл торцов обрабатываемых изделий выполнены из огнеупорного изол ционного материала, с целью предохранени торцов обрабатываемых изделий от онлавлени .The form of the device according to ed. St. No. 64508, characterized in that the holes for the ends of the products to be machined are made of refractory insulating material, in order to protect the ends of the products being processed from chipping.
