Description

The invention relates to the production of building products, namely, devices for the manufacture of tubular products from hardening mixtures.

The purpose of the invention is to increase productivity.

FIG. 1 shows the proposed device, a general view; FIG. 2 is a section A-A in FIG. t; in fig. 3 - product, cut; in fig. 4 - device, section; in fig. 5 is a section BB in FIG. four; in fig. 6 is a sectional view BB in FIG. four. .

The device for the manufacture of tubular products has a cylindrical core 1, which is cantilever mounted on a support 2, connected through a reducer 3 with a drive 4 of rotation of the device. On the support 2 in bearings the worm gear 5 is mounted, made together with the cylindrical gear 6. The gears 5 and 6 form a synchronizing mechanism and a gear

The mounting on support 2 is rotatably free. Gear 6 engages with gear wheel of high-speed shaft 7 connected to drive 4. High-speed shaft 7 and bearing 2 are installed in bearings 8. Worm gear 5 engages with worm wheels 9 located around the circumference of cylindrical core 1. To each worm The wheel 9 is attached to the drive rollers 10, made in the form of sprockets, which can rotate on their own axles, mounted on brackets 11. On the driving 10 and driven 12 rollers, the tensioned traction elements in the form of chains 13, the outer branches of which are held in azah cylindrical core protrusion above the surface. Under the core 1, the pinch rollers 14 are mounted on their own frames. To form the inner and outer surfaces of the product 15, there are flexible elements wound on reels 16. Depending on the width of the paper tape 1202091

 The reel axis is set at a certain angle relative to the axis of the core 1. An apparatus with an outlet 17 serves to supply the hardening mixture between the flexible tapes 5 from the reel 16. A cutting device 18 is installed in the course of the finished product. the inner shell, between which is hardened mass.

The device works as follows.

Before starting work, the flexible tapes from the reels 16 are filled, for which two or three turns are formed on the core 1 without feeding the hardening mass. This operation is also carried out when replacing the consumed bobbins 16. After testing the tension and reliability of storing the tapes from the apparatus 17, a solid mixture is supplied, which is distributed between the flexible elements. The inner diameter of the pipe is calibrated by a cylindrical core 1, the outer diameter by rollers 14. Rotation from drive 4 through gear 3 and support 2 is transmitted to core 1. At the same time, through the high speed shaft 7 and gear 6, the rotation is transmitted to the worm gear 5, which rotates through wheel 9 rollers 10. Summing the rotation of the wheels 9 around the support 2 and the rotation of the gear 5 from the shaft 7, the chains 13 acquire the estimated speed of movement together with the product being manufactured. The movement of the finished product along the core 1 is due to the friction of the chains 13 that protrude beyond the surface of the core, and for one revolution of the core is ready | The pipe moves one step smaller than the width of the tape, which are overlapped. The process of manufacturing the product is carried out continuously and the pattern of the product continuously descends from the core 1. On the path of movement, the finished product is cut to a predetermined length of segment.
