Description

Изобретение относитс  к области оборудовани  дл  переработки полимерных материалов , в частности к конструкции черв чных прессов. Известен черв чный пресс дл91 переработки полимерных материалов, оснащенный формующей головкой, дорн которой жестко соединен со шнеком |l. Недостатком пресса  вл етс  невозможность независимого вращени  дорна, что не позвол ет получать издели  высокого качества. Наиболее близким к изобретению по тех нической сущности  вл етс  черв чный прес дл  переработки полимерных материалов, содержащий корпус, полый черв к с приводом его вращени  и формующую головку с мундштуком и коническим дорном, снабженным валом, проход щим через полость чер- в ка и соединенным с приводом вращени  дорна 2. Недостатком указанной конструкции  вл етс  отсутствие осевого перемещени  дорна, что не позвол ет регулировать сте пень разогрева перерабатываемого материала и получать издели  хорошего качества. Цель изобретени  - повышение качества изготавливаемых изделий путем регулировани  степени ршзогрева перерабатываемого материала. Цель достигаетс  тем, что пресс снабжен механизмом осевого перемещени  дорна, выполненным в виде упорного подшипника дл  креплени  дорна и упорной гайки, соединенной кулачками с приводным валом, расположенным снаружи вала дорна в полости черв ка, который выполнен с внутренней нарезкой, взаимодействующей с резьбой гайки. Конструкци  черв чного пресса показана на чертеже. Черв чный пресс содержит корпус 1, в котором помещен полый приводной черв к 2, формующую головку, включающую конический дорн 3 и мундштук 4. Дорн снабжен приводным валом 5, проход щим через, внутреннюю полость черв ка 2 и установленным в радиально-упорном подшипнике 6.The invention relates to the field of equipment for processing polymeric materials, in particular, to the design of screw presses. Known screw press for 91 processing of polymeric materials, equipped with a forming head, the mandrel of which is rigidly connected to the screw | l. The disadvantage of the press is the impossibility of independent rotation of the mandrel, which does not allow to obtain high-quality products. The closest to the invention in terms of technology is a screw press for processing polymeric materials, comprising a housing, a hollow screw with its rotational drive, and a die with a mouthpiece and a conical mandrel provided with a shaft, passing through the cavity, and connected Rotary-driven Dorn 2. The disadvantage of this design is the lack of axial movement of the mandrel, which does not allow to adjust the degree of heating of the processed material and to obtain good quality products. The purpose of the invention is to improve the quality of manufactured products by adjusting the degree of heating of the processed material. The goal is achieved by the fact that the press is equipped with a axial movement mechanism of the mandrel, made in the form of a thrust bearing for fastening the mandrel and the thrust nut connected by cams to a drive shaft located outside the shaft of the mandrel in the cavity of the screw, which is made with an internal thread interacting with the nut thread. The design of the screw press is shown in the drawing. The screw press comprises a housing 1 in which a hollow drive screw to 2 is placed, a forming head including a conical mandrel 3 and a mouthpiece 4. The mandrel is equipped with a drive shaft 5 passing through the internal cavity of the screw 2 and installed in an angular contact bearing 6 .
