Abstract
The present invention relates to a press of pressure cell type, a tray for use in a press of pressure cell type and a method. The tray comprises a tray frame, which defines a space for arranging a forming tool and/or a work-piece. Prestressing means are arranged on the external surface of the tray frame and induce a compressing prestress which acts in planes parallel to the plane of the tray. The tray frame presents a curvature along its entire circumference.
Claims41
A press of pressure cell type, which comprising a tray and a force-absorbing press body, wherein the press body encloses a press chamber, into which tray is introducible, and the tray comprises a tray frame which defines a space for arranging at least one of a forming tool and a workpiece, wherein prestressing means, which induce a compressing prestress which acts in planes parallel to the plane of the tray, are arranged on the external surface of the tray frame, and wherein the tray frame presents a curvature along its entire circumference.
A tray for use in a press of pressure cell type, the tray comprising:
- a tray frame which defines a space with the purpose of arranging at least one of a forming tool and a workpiece, and prestressing means, which induce a compressing prestress which acts in planes parallel to the plane of the tray, arranged on the external surface of the tray frame, wherein the tray frame presents a curvature along its entire circumference.
A method for manufacturing a tray for use in a press of pressure cell type, comprising the steps of:
- forming the tray of steel plate, the tray comprising a tray frame, wherein the tray frame is formed such that it presents a curvature along its entire circumference;
- and
- inducing a remaining compressing prestress in the tray, the prestress acting in planes parallel to the plane of the tray.
