Abstract
A material 1 to be shaped is reduced and formed by bringing dies with convex forming surfaces, when viewed from the side of the transfer line of the material 1, close to the transfer line from above and below the material 1, in synchronism with each other, while giving the dies a swinging motion in such a manner that the portions of the forming surfaces of the dies, in contact with the material 1, are transferred from the upstream to the downstream side in the direction of the transfer line.
Claims4
A plate reduction press apparatus comprising:
- a press-side speed adjusting roll and a rolling-mill-side speed adjusting roll, each speed adjusting roll having a transfer speed and disposed to measure a length of a material to be pressed, the speed adjusting rolls arranged between a reduction press machine and a rolling mill, with a space provided in which the material to be pressed can be deflected;
- and
- a control apparatus for controlling the operations of the reduction press machine and adjusting the transfer speed of the press-side and the rolling-mill side speed adjusting rolls according to a measurement of the press side and the rolling-mill side speed adjusting rolls.
