Description

The invention relates to the processing of reinforced plastics by the winding method and can be used in various sectors of the national economy in the manufacture of long tubular articles.

The purpose of the invention is to increase reliability.

FIG. 1 shows a diagram of the device; figure 2 - section aa in figure 1; on fig.Z - scan the working surface of the device with cams and sector slats.

A device for manufacturing tubular products comprises a composite shaft of parts 1 and 2 mounted in rolling bearings 3, on which a drive gear 4 is rigidly fixed on one side. The connection of part 1 of the shaft with part 2 is carried out using a centering sleeve 5 and clamping flanges 6 and 7. Sector strips 8 are installed on shaft part 2, on which body 9 is located. Sector strips 8 are connected to shaft part 2 by means of a key 10 and are equipped with fingers 11 on which conical rollers are freely seated 12. Housing 9 is equipped with bearings 13, toothed stake by weight 14 and by a copier in the form of rings 15 and 16 with profile elements 17 and 18 rigidly attached to them with a slope of the profile edge equal to the angle of taper of the rollers 12 and forming a copier track that interacts with the conical rollers of 12 sector slats 8. On the body 9 pivotally mounted coils 19 with a release tape 20. The device is provided with a winding head (not shown) with a wound reinforced material 21. Sector strips 8 are made so that their outer surface corresponds to the inner surface of the forming pipe 2 2

The apparatus for making tubular products works as follows.

Through drive gear 4, the shaft of parts 1 and 2 is driven into rotational motion. The rotation of the shaft is transmitted to the sector bars 8 placed on it.

On the strips 8, anti-adhesive tapes 20, unwound from the reels 19, and the winding reinforced

material 21. When the planks 8 rotate on their working surface, a pipe 22 is formed. At the same time, the tapered rollers of the 12 sector planks 8, interacting with the copier track formed by elements 17 and 18, communicate the planks 8 with translational movement, moving the coiled pipe 22 along the strips 8. The profile of the copier track is designed so that at any time, a larger number of sector strips 8 move in the direction of movement of the product, and during one revolution of the shaft of the plank 8, two forward and two reverse moves are made along the shaft part 2. When a copier body 9 is connected through the gear 14 to the drive, it begins to rotate. At the same time the progress of the sector strips 8

in the longitudinal direction decreases depending on the ratio of the speeds of rotation of the shaft and the body 9 of the copier. The gap between the rollers 12 and the cams formed during the operation is eliminated by turning the rings 15 and 16, on which

fixed elements 17 and 18.

The proposed implementation of the track in combination with the tapered rollers of 12 sector slats 8, which interact with it, improves the reliability of the device.
