Device for stretching a metal semi-finished product in the form of individual plates along a stretching section with a stretching frame, and method for stretching a metal semi-finished product using the device

A device for stretching a semi-finished metal product in form of individual plates along a stretching section, comprising:

• a stretching frame (2), comprising
• a first pressure column (7) and a second pressure column (8) extending in an axial direction of the stretching section,
• a first stretching cylinder (5) supported on the first pressure column (7),
• a second stretching cylinder (6) supported on the second pressure column (8),
• a first stretching rod (9) aligned with the first pressure column (7), the first pressure column (7) forming an abutment for the first stretching rod (9), and
• a second stretching rod (10) aligned with the second pressure column (8), the second pressure column (8) forming an abutment for the second stretching rod (10);
• a first clamping head (3) in which a first short side of the semi-finished metal product to be stretched can be clamped, the first clamping head (3) being axially movable within the stretching frame (2) by the first stretching cylinder (5) and the second stretching cylinder (6);
• a second clamping head (4) in which a second short side of the semi-finished metal product to be stretched can be clamped;
• and
• an axial inlet and an axial outlet of the stretching frame (2),
• wherein the first clamping head (3) and/or the second clamping head (4) is designed such that the semi-finished metal product to be stretched can be guided axially through the first clamping head (3) and/or the second clamping head (4).
