Tool heads for presses

Abstract

The invention relates to a tool head (10) for a press (1) and a press for plastically deforming tubular workpieces, in particular joints, wherein the tool head comprises a base body (12), A fixed clamp (14) and a linearly movable clamp (16). The spring element (18) is provided for prestressing the movable press jaw against the workpiece without plastically deforming the workpiece.

Description

technical field [0001] The invention relates to a tool head for a press, in particular a tube press, for plastically deforming tube-shaped workpieces, in particular joints. Furthermore, the invention relates to a press and a method for operating such a press. Background technique [0002] Various methods are known in the prior art for connecting tubular workpieces. For example, the tubes can be welded or welded to each other. It is also known to insert the end of a smaller tube into the tube end of a larger tube and then press the two tube ends together. [0003] In other cases, extrusion is performed by means of (extrusion) joints. For this purpose, a press, for example a tube press, can be used to connect the tube with the extruded connection. Such a connection can be designed, for example, as a pipe connection, which can be used as a connection for pipes. The pipe ends to be connected are inserted into the fitting and the fitting is then pressed together with the pip...

Problems solved by technology

[0006] Furthermore, the known tool heads are bulky and can only be used to a limited extent in tight areas

In particular due to the relative pivoting of the pliers relative to one another, the surrounding volume of the known tool head changes very strongly when the pliers are opened, so that the known tool head is unsuitable or only limitedly suitable for use in confined areas ( e.g. when installing air conditioning or heating, especially when retrofitting air conditioning or heating modules)

[0007] Furthermore, the known tool heads are often difficult to position precisely enough so that the workpiece (joint) to be extruded is not ideally clamped prior to extruding

This can lead to deformations of the workpieces at locations that are not provided for deformations, so that the tightness of the joints of tubular workpieces cannot be ensured in the end.
