Problems solved by technology

Overhead cranes in general also cost a lot of overhead and are often used for different purposes in a machine room or factory, so may not be available when a box needs to be converted
Sometimes an overhead crane is simply not available
More importantly however, the overhead crane is only allowed to carry one box away from or towards the production line at a time, so boxes can only be replaced one by one
Therefore, it is very time-consuming to replace the box with an overhead crane

Embodiment Construction

[0025] FIG. 1 shows a top view of an exemplary embodiment of a conversion system 1 according to the invention. As mentioned above, the conversion system 1 is suitable for use in metal forming machines, especially tube forming machines. The material flow to be formed, eg metal strip, is indicated by arrow F.

[0026] It can be seen from FIG. 1 that the conversion system 1 includes at least one pair of working assemblies, and each pair of working assemblies includes two working assemblies 10 and 11 . The two working assemblies 10, 11 (for example the forming pass and the frame) are adapted to pivot into and out of the line of work stations of the forming machine, as will be explained below. For example, the working assemblies 10, 11 are pivotably connected at opposite ends to a production line consisting of workstations. The working assembly 10 is located on the line of forming machines consisting of workstations, while the working assembly 11 is in an off-line position. Two ...

Abstract

A changeover system (1) for a metal forming mill, in particular for a tube-forming mill, comprises at least one pair of work modules (10,11), the work modules of which are adapted to be pivoted (P1,P2) into and out of a line of work stations of the mill. Each work module (10,11) has its own drive or drives. Within a pair of work modules the two work modules (10,11) are arranged such, that when one work module (10;11) is arranged in the line of work stations the other one (11;10) is arranged off the line. <IMAGE>

Description

technical field [0001] The invention relates to a switching system for a metal forming machine. Background technique [0002] In the manufacture of many types of metal products, such as in the manufacture of formed metal parts or pipes, the metal is formed to obtain the desired shape. Especially in tube forming machines for the production of welded seam tubes, the continuous metal strip advances through several stations making up the production line. In these stations, the metal strip is formed into a tubular shape having an open longitudinally extending slot formed by adjoining edges of the metal strip being formed. The seam is then welded, and a trimming operation may be performed to remove the bead in order to prevent the formation of unwanted weld beads. Obviously, the welding and subsequent trimming steps can be omitted when producing pipes other than welded seam pipes. [0003] Since this type of forming machine comprises many large-scale precision machines at great...
