Description

Как известно, стоимость лить  в посто нныеформы выше, нежели стоимость отливки в песке. Также и отливка бронзовых сплавов на машинах под давлением обходитс  дороже, нежели отливка в песке.As is known, the cost of pouring into permanent forms is higher than the cost of casting in sand. Also, casting bronze alloys on pressurized machines is more expensive than casting in sand.

Повышение стоимости отливок, полученных в посто нных формах, объ сн етс  наличием расходов на изготовление и содержание самой формы, так .как чугунные, а также и стальные формы при их высокой стоимости слишком быстро выход т из стро . Хот  стальные формы и сохран ютс  дольше, но их стоимость значительно выше чугунных. и поэтому предпочитают последние.The increase in the cost of castings produced in permanent forms is explained by the existence of costs for the manufacture and maintenance of the form itself, such as cast-iron as well as steel forms, at their high cost, come out too quickly. Although steel forms remain longer, their cost is much higher than that of cast iron. and therefore prefer the latter.

Причиной выхода из стро  формы  вл етс  главным образом рост чугуна в чугунных формах, внутренние напр жени  в чугунных и стальных формах, а также коробление стальных форм. Кроме того, изготовление чугунных форм негативным способом не всегда возможно , формы получаютс  не рельефные и требуют дополнительной обработки .The cause of failure of the mold is mainly the growth of cast iron in cast iron forms, internal stresses in cast iron and steel forms, as well as the buckling of steel forms. In addition, the manufacture of cast iron forms in a negative way is not always possible, the forms are not embossed and require additional processing.

Дл  увеличени  срока службы металлических форм предлагаетс  изготавливать их способом прессовани  и по (235)To increase the service life of metal molds, it is proposed to manufacture them by the method of pressing and according to (235)

следуюш,его спекани  из порошкообразных смеси металлических порошков, например, железа или меди с добавкой графита, талька, шамота и т. п.Next, its sintering of powdered mixture of metal powders, for example, iron or copper with the addition of graphite, talc, chamotte, etc.

Дл  этой цели достаточно изготовить лишь одну прессформу, прикрепив внутри ее образец будуш,ей отливки и по ней отпрессовывать и затем спекать .как это делаетс  при изготовлении металлокерамических изделий) форму дл  отливки в любом количестве.For this purpose, it is enough to manufacture only one mold, attaching a sample of a mold inside it, casting and squeezing it over it and then sintering it. As it is done in the manufacture of metal-ceramic products, the mold for casting in any quantity.

Применение нового способа изготовлени  форм дл  отливки в посто нные формы, отливки под давлением и отливки центробежным способом имеет в виду значительно удешевить изготовление формы, затем увеличить сроки службы каждой формы по сравнению с чугунной, так как не будет растрескивани  и короблени  формы; при этом форму можно делать более тонкой, так как теплопроводность металлокеракических изделий ниже, чем чугуна и стали.The use of a new method of making molds for casting in permanent forms, casting under pressure and casting by the centrifugal method means to significantly reduce the cost of making the mold, then increase the service life of each mold compared to cast iron, since there will be no cracking and warping of the mold; at the same time, the shape can be made more subtle, since the thermal conductivity of metal-carving products is lower than that of iron and steel.

При литье чугуна возможно, благодар  меньшей теплопроводности, гарантировать получение отливкиу-6 за1 аленного сло .When casting iron, it is possible, due to the lower thermal conductivity, to ensure that the casting-6 is obtained for the alene layer.

Предмет изобретени . Способ изготовлени  литейных форм, отличающийс  тем, что их получают известным самим пв себе способомThe subject matter of the invention. A method of making casting molds, characterized in that they are prepared in a manner known per se.

прессовани  и последующего спекани  порошкообразной смеси металлических порошков с добавкой графита, талька, шамота и т. п.pressing and subsequent sintering of a powdered mixture of metal powders with the addition of graphite, talc, chamotte, etc.
