专利说明:

The invention relates to the processing of metals by pressure, in particular to dies for bending shells.
A device for stepwise bending a cylindrical shell of a flat 5 plastically deformable blank of a sheet material or plate containing a matrix mounted on a base plate, made with two parallel bending ribs located 10 apart from each other, a bending support mounted on the side feed the workpiece and made with a height exceeding the height of the matrix, and fixed on a movable plate 15 punch with a working part located in the center between the bending ribs of the matrix [ij.
However, the known device does not provide a high-performance 20 bending of the edges of the workpiece.
The aim of the invention is to increase productivity.
The chain is achieved by the fact that the device for stepwise bending 25 of a cylindrical shell from a flat plastically deformable billet of a sheet metal or plate containing a matrix mounted on a base plate, made with two parallel 30 integral bending ribs located at a distance from each other, a bending support mounted on the supply side of the workpiece and made with a height exceeding the height of the matrix, ₃₃ and a punch secured to a movable plate. the working part, located in the center between the bending ribs of the matrix, is equipped with an additional support mounted externally to the second bending rib, and each bending support is equipped with a turning mechanism for withdrawing it from the working area and entering it connected with a hydraulic or electrical device _{45 with} water, and the base plate is mounted with the possibility of reciprocating movement along the feed direction of the workpiece.
The drawing shows a device for stepwise bending of a cylindrical shell.
The device comprises a base plate 1, a matrix mounted on the plate, with two parallel bending ribs 2 and 3 placed at a distance from each other, bending supports 4 and 5 with a height exceeding the height of the ribs 2 and 3 of the matrix, containing rotary parts 6 and 7.
The device contains a takke punch '8 with a working part 9, placed between the bending ribs 2 and 3.
The base plate 1 is installed with the possibility of reciprocating movement along the feed direction of the workpiece 10. On the rotary parts 6 and 7 of the supports 4 and 5 and the bending ribs 2 and 3 are replaceable inserts 11. The rotation of the parts 6 and 7 is carried out from the rotation mechanisms associated with the drives 12 and 13.
The device operates as follows.
The rotary part 7 of the support 5 is introduced into the working area, the base plate 1 is shifted to the right so that the axis of the punch 8 approaches the edge 3 by the amount of the bend end and bend one end of the workpiece 10. Then, the rotary part 7 of the support 5 is brought out of the working area and introduced the rotary part 6 of the support 4, move the base plate 1 to the left and similarly bend the other end of the blank 10.
At the end of the bending of the ends, the rotary part 6 of the support 4 is brought out of the working area and the base plate is moved so that the bending ribs 2 and 3 are symmetric to the axis of the punch 8, and stepwise bending the shell.
This device provides both cold and hot bending of shells.
