Description

A machine for folding the edges of casing skins in en-tare by rolling between the profiling rollers is known.

In comparison with the known, the described machine has a higher productivity, which is achieved by double-sided folding by two pairs of profiling rollers, along the copier, and along the profile of the edges of the casing skin.

The profiling rollers are movable and, and the distance between the two is set to the width of the foldable skin.

The aaroTOBKiH clamp to the copier during the folding process can be provided with two circular, two (supporting M, and two pressure rollers) freely put on the shaft.

FIG. 1 shows a kinematic diagram of the machine; in fig. 2 is a diagram of a copier with forming rollers.

The drive shaft / reversibly rotates in stationary bearings. Two leading rollers 2 are mounted on the shaft 1 with the help of dowels. A gear system drives the shaft / transmits rotation to the movable shaft 3, on which two profiling rollers 4 are fixed, providing two-sided folding on 1capier, made along the profile of the fan casing trim. The movement of the shaft 3 up and down is carried out manually (by the drive 5 and allows the folding of the skins of the various shirina. On the shaft 5 between rollers: and 4, two steel red-hot ring rollers 6 are in contact with the two supporting rollers 7 and pressure rollers 8.

The purpose of the annular rollers 6 is to, in the place of flanging the casing, carry out a constant pressing of the spiral casing 9: to the copier 10, and the latter to the leading rollers 2. Diameter

holes of the annular rollers 6 is selected in such a way as to provide the necessary working movement of the shaft S.

Under the profiling rollers 4 there are two supporting knives 11, whose purpose is to bend the flange flange inward, to the required angle. On both sides of the leading rollers 2 there are rollers, 12, which hold the copier 10 from tilting during operation. The operation on the wall is carried out as follows: the spiral lining 9 of the fan is placed in the copier 10 in the direction indicated by arrow A, and pressed tightly against the inner surface of the copier so that K | ra the plating evenly protruded on its side. Further, rolling rollers 12 in the machine opened into the machine, close its shed and fix its folding part. Then, the profiling rolls on / 4 the depth of flanging, they drive the copier two times to the right and B1 to the left. Rolling a copier from the machine to the trolley and closing its mouth, lay the side posts. The fan's heels into the prepared abacus folds and with the help of pianmapic rammers, located on both sides of the copier, simultaneously and squeezing the folds gradually, turning the capir gradually. then rol-ikam on the te
