SU16408A1 - Device for strengthening the barrel barrel when turning it outside - Google Patents

Description

In the present invention, with regard to devices for strengthening the barrel core when turning it outside, a shaft with two couplings mounted on it, having conical grooves, into which the inclined parts of the elastic legs of the holders of the end parts of the frame can be pushed and pulled. at

When the holders are moved out of the conical recess to the outside, their tabs abut against the barrel and secure it with their elasticity silt.

In the schematic drawing, FIG. 1 depicts a top view of the proposed device; FIG. 2-view of the star holder.

The shaft 4 of the machine 1 is rigidly fitted with two couplings 5 with conical grooves 10, inside which the inclined parts 9 of the clamps 6 of the holder can move (Fig. 1). The star-shaped holders composed of these legs (Fig. 2) are mounted on the shaft 4, which at the ends is provided with sleeves 8 screwed onto it with handles 7.

When turning the core, the holders using the handle 7 are extended. it is secured from the recesses 10 to the outside and by the elastic force of the legs.

The turning is performed by a cutter fixed in a support 3 (Fig. 1), which can be moved along the machine 1 by means of a screw 2.

The subject of the patent.

A device for strengthening the skeleton of the barrel when turning it outside, characterized by the use of couplings 5 fastened to the shaft 4 of the machine with conical grooves 10, including, each, inclined parts 9 of the tabs 6 of two elastic star-shaped, for the end parts of the skeleton, holders squeezed out of the grooves 10 to the outside, for fastening the barrel, by its elasticity and moving inward, in order to remove the trimmed core and put on a new one, by rotating the handle 7, which are worn with screwed sleeves, on the cut parts of the shaft 4.
