Description

The invention relates to the processing of materials by pressure, in particular to equipment for the manufacture of corrugated elbows from metal or plastic sheet blanks.

A device is known for the continuous forming of profile products from a sheet blank, comprising a purple blank supply unit, a forming mechanism made in the form of parallel rows of end upper and lower chains with profile elements that are mounted green with the possibility of pairwise engagement (L1) , and gauge guides.

The disadvantage of this device is that it contains a separate table for transverse cutting of corrugated material, increasing its dimensions and material capacity, and also such a device does not provide corrugation of large and irina ribbons.

 Closest to the proposed is a device for corrugating the tape,

comprising a belt feeding unit and a forming mechanism including parallel endless chains mounted on pairs of sprockets, one in each pair of which is driven, and profiled prismatic working elements fixed on parallel chains.

The disadvantage of this device is the limited technological capabilities due to the corrugation of the tape of small width and only of metal tape, and only one step of the corrugations.

The purpose of the invention is the expansion of technological capabilities due to the corrugation of large-width tapes, the various steps of the corrugations after readjustment, and the corrugation of the tape from both metal and plastic, as well as the provision of both longitudinal and transverse cutting of the tape.

This goal is achieved by the fact that the device for corrugating the tape containing the site of the feed tape and the forming mechanism, including parallel

The working elements can be made of metal, thermosetting plastic, wood and in cross section triangular, hemispherical, wavy, etc., depending on the desired shape of the corrugations of the finished products. The working elements are fixed on the outside of the chain 9, c. e-- at the end of the transmission gear 7 i

5 is made in the form of groups of teeth placed inside the group with a nominal step, and between adjacent groups with a step that is a multiple of the nominal (Fig. 3 and 7). for traction with a chain of 9 gears

0 7, the last in the intervals between the groups of teeth have gaps 12, obtained by removing one or two teeth depending on the size of the screw head 11. On the working elements 10, knives 14 (Fig. 7) are installed with a given 5-step pitch for transverse cutting of products in the process of shaping them. Besides the fact that one shaft is driven and contains a drive sprocket 4 (Fig. 4), the other shaft additionally contains an asterisk 15 (Figs. 2 and 3), connected by a chain gear 16 through an asterisk 17 to a shaft 19 of the longitudinal cutting mechanism . The sprocket 17 on the shaft 19 is fixed with a nut 18 (Figs. 1 and 5). The mechanism of longitudinal cutting of products (Figs. 1, 5, and 6), in addition to the shaft 19 installed in the separable bearings 20, contains disk knives 21 fixed to it, between which spacers are installed

0 bushings 22, equal to the width of the cut products. Yozhi 21 is paired with a plate 24, the blades of which can be placed in the slot 23 with cutting edges along their perimeter. The device contains
