Abstract

The invention relates to devices for the manufacture of lengthy, including reinforced polymer products. The purpose of the invention is to improve the quality of products, as well as to ensure the possibility of manufacturing tubular products. For this, the calibrating rotating means is made of a coaxially arranged core 3 with radial 4 and axial 5 communicating with the opening 6 for supplying the reinforcement with polymer channels and the sleeve 7 connected to it, which has a supporting ring fixed to the core and an anti-friction element for interacting with the end of the device body. For the manufacture of tubular products, the device is completed with a calibrating tip connected to the sleeve 7 and the profiling head located on it, while the opening 6 for feeding long-length reinforcement is closed with a plug. During the supply of the polymer melt, the core and its associated elements are rotated to ensure that the coating or tubular product is even and the polymer is compacted. 1 hp f-ly, 2 ill.

Description

Phie.1

The invention relates to devices for the manufacture of long-length articles with fittings, such as electrical conductors, as well as for the manufacture of tubular products.

The purpose of the invention is to improve the quality of products, as well as to ensure the possibility of manufacturing tubular products.

Figure 1 shows the device section; Fig. 2 is the same, a variant for the manufacture of tubular products.

The device comprises a housing I with a channel 2 for feeding the polymer and a calibrating, rotating means, which is made up of coaxially arranged core 3 with radial 4 and axial 5 communicating with the opening 6 for feeding long-length reinforcement, channels for polymer and an associated sleeve 7, on which is mounted a support ring 8 which is rigidly connected to the core 3 with an antifriction element 9 for interacting with the end face of the housing 1. A gear JO is installed on the core for communication with the drive.

For the manufacture of tubular products, the device is provided with a calibrating threaded connection connected to the sleeve 7, with an axial 11 and radial 12 channels connected to it with a polymer tip 13, a plug 14, a hole 6 on the core 3 for feeding long fittings and located on the calibrating tip 13 and fixed to the housing 1 profiling nozzle 15.

Such a constructive solution ensures the equivalence of products and compaction of the polymer material.

The device works as follows.

The metal wire, which has passed through the degreasing process, is passed through the device, is fixed in the traction organ of the receiving drum of the production mechanized line, after which the prestressing is performed. Then, the wire is transmitted in a tensioned state. Simultaneously, a melt of polymer that covers the wire and, gradually lowering the temperature, moves through the sleeve 7 (the latter can be cooled, for example, with running water) to the gauge

 sealed by the surface of the sleeve. A plastic lining is formed on the wire surface, molded from the melt. In this case, due to the rotation of the sleeve 7 around the tensioned wire, the facing of the lining and compaction of the polymer layer of the material is ensured.

If necessary, the manufacture of plastic pipes, shells, hoses, etc. make changeover of the device. Install the plug 14 on the gasket closing the opening for feeding the fittings. On the sleeve 7, the tip 13 is coaxially fixed on the gasket, then the profiling nozzle 15 is mounted concentrically and fastened to the body 1 by means of a glass. When the polymer melt is supplied, the polymer enters the channel of the sleeve 7 and through the channels 11 and I2 of the tip 13 into the forming cavity formed by the profiling nozzle 15. As the polymer moves through the cavity, the polymer is mechanically calibrated and sealed by the outer surface of the rotating tip 13. lugs 13, profiling nozzles 15, can be produced over a wide range of sizes, coated electrical wires and polymer shells in the form of pipes, etc.
