Description

The invention relates to the field of engineering, mainly chemical. .

A known installation for the manufacture of fiberglass pipes, comprising a mandrel, a coiled material stacker, polymerization chambers and a cutting device. Cl The disadvantage of this device is that it is manufactured. limited by the length of the mandrel.

A device is also known to produce fiberglass pipes, comprising a frame attached to it and equipped with a driving mechanism, a mandrel in a form. a number of joined sections, a stacker,; polymerization chambers and a detachable ,, device C2 ..

The disadvantages of this installation are the complexity of the design and the large laboriousness of manufacturing glass plastic pipes. ;

The aim of the invention is to simplify the design and reduce the TP5 dregs of fiberglass manufacturing of lx pipes.

This goal is achieved by the fact that in a plant for manufacturing fiberglass pipes, containing a frame, mounted on it and equipped with a drive-driven rotation mechanism, a mandrel in the form of a series of coupled sections, a stacker, polymerisation chambers and a cutting device, the transferring mechanism is made view of a fixedly mounted on the frame concentrically inside the mandrel of the 10 log rods with a rectangular thread, interacting with the pins attached to the sectors forming the sections of the mandrel with the ability An engagement with a rotating carriage mounted on the frame.

FIG. 1 shows the installation, general VIEW} in FIG. 2 - section: A-; in fig. 1 in FIG. 3 - node I on. FIG. one..

On the base 1, a rotating mechanism mounted in the form of a 25, made in the form of a hollow rod 4 fixedly mounted on the frame concentrically inside the mandrel of a hollow rod 4 with a rectangular thread, interacting with a pin 30 of iTajipi 5 mounted on the mandrel sectors 3. Sectors 3 are mounted to engage rotating carriage 6 mounted on frame 1 through openings 7 made in them. The carriage is driven by electric motor 8 through gear pair 9. The installation is also equipped with guide sleeves 10, basket-type gukadchik 12 and polymerization chambers 13. The installation operates as follows. An electric motor rotates a sliding carriage b, which rotates sections 2 of the mandrel. Sliding along the grooves on the rod 4, the pins 5 sectors perform axial movement of the entire set of sections 2 of the mandrel, and hence the finished pipe, which is molded with a stacker and polymerizes in the polymerization chambers. The finished pipe is cut off using a cutting device, the sectors are extracted and delivered to the beginning of the process line. Thus, the design of the installation is simplified and reduced by the difficulty of manufacturing pipes made of fiberglass at a high manufacturer (Installation details. Formula of the invention Installation for the production of fiberglass pipes containing a frame attached to it and equipped with a driving mechanism, rotating in the form of Yes, joined sections, a stacker, polymerization chambers, a cutting device, characterized in that, in order to simplify its design and reduce the labor intensity of manufacturing GRP pipes, The e-rotating mechanism is designed as a fixedly mounted on the frame concentrically in the morning of the mandrel of a hollow rod and a rectangular thread interacting with pins attached to the sectors forming the sections of the mandrel that engage with the rotating carriage mounted on the frame. taken into account during the examination 1.
