Description
(54) СПОСОБ ФОРМОВАНИЯ РАСТРУБОВ С КОЛЬЦЕВОЙ ЗИГОВКОЙ(54) METHOD OF FORMATION OF RUBLES WITH RING SHOPPING
Изобретение относитс к переработке термопластичных полимерных материалов, в частности , дл изготовлени раструбов с кольцевьши канавками на трубах.The invention relates to the processing of thermoplastic polymeric materials, in particular, for the manufacture of sockets with annular grooves on the pipes.
Известны способы формировани раструбов 5 с кольцевым пазом или желобом, заключающиес в том, что раструб разогревают в месте , где должен быть образован паз, и внутрь его ввод т сердечник, снабженный камерой повышенного давлени и формующим коль- Ю цом, а вокруг трубы устанавливают разъемную форму. Затем производ т расширение кольца и формуют кольцевой паз на раструбе. Недостатком указанного способа вл етс некоторое утонение стенки раструба в месте 15 кольцевого паза, что приводит к снижению качества издели .Methods are known for forming sockets 5 with an annular groove or groove, consisting in that the socket is heated in the place where the groove should be formed, and the core equipped with the plenum chamber and the forming ring is inserted into it, and a detachable form. Then the ring is expanded and an annular groove is formed on the socket. The disadvantage of this method is some thinning of the wall of the socket in place 15 of the annular groove, which leads to a decrease in product quality.
Наиболее близким решением из известных вл етс способ формовани раструбов с кольцевой ЗИГОВКОЙ путем предварительного 20 нагрева формуемого участка с последуюш,им осевым осаживанием заготовки 2. Недостатком указанного способа вл етс невозможность обеснечени точных размеров изготавливаемой зиговки.25The closest solution known is the method of forming sockets with ring ZIGOVKA by preheating the molded section with the subsequent, axial settling of the workpiece 2 with them. The disadvantage of this method is the impossibility of finishing the exact dimensions of the zigging being made.25
С целью обеспечени точности диаметра зиговки используют полученную литьем под давлением заготовку с цилиндрическим раструбным участком, переход ш,им в цилиндрический-головной участок с большим диаметром, причем головной участок сужают в радиальном направлении, начина с торцевого конца.In order to ensure the accuracy of the zigzag diameter, an injection molded billet with a cylindrical socket part, a transition w, into a cylindrical-head section with a large diameter, the head section being narrowed in the radial direction, starting from the end end.
На фиг. 1-3 изображены этапы формовани раструба с кольцевой зиговкой.FIG. 1-3 depicts the steps of forming a bell with a ring zigovka.
Описанный способ заключаетс в следуюшем: трубчатую заготовку 1, полученную литьем под давлением с цилиндрическим раструбиым участком, переход щим в цилиндрический головной участок 2 с большим диаметром , устанавливают в опорной втулке 3 с упором в торцовую поверхность втулки 3; цилиндрический раструб с головным участком 2 нагревают и, перемеща подвил ную плиту 4, ввод т в него дорн 5. Одновременно с этнм формующее кольцо 6 деформирует передние кромки головного участка и при этом образуетс кольцева заготовка на конце головного участка 2.The described method consists in the following: a tubular billet 1, obtained by injection molding with a cylindrical socket part, passing into a cylindrical head section 2 with a large diameter, is installed in the support sleeve 3 with an emphasis on the end surface of the sleeve 3; the cylindrical bell with the head section 2 is heated and, by moving the basement plate 4, the mandrel 5 is inserted into it. Simultaneously with the forming ring 6, the forming ring 6 deforms the front edges of the head section and a ring blank is formed at the end of the head section 2.
После охлаждени формованного участка из него извлекают дорн 5 и формующее кольцо 6 и получают отформованную кольцевую зиговку на конце трубы.After cooling the molded section, the mandrel 5 and the forming ring 6 are removed from it and a molded annular zigovka is obtained at the end of the pipe.
