Device comprising a housing and a rotary element mounted in the housing such that it can be rotated and axially shifted

A device having a housing (2) and a rotary element (4) mounted in the housing (2) such that it can be rotated and axially shifted (14). In order to reduce bearing loads in the rotary element (4), with eccentric loading of the rotary element (4), the device provides at least one first support surface (6) on an end side (8) of the rotary element (4) and a second support surface (10) axially, opposite (40) the first support surface (6) on the housing (2). The rotary element (4) is then mounted in the housing (2) in such a way that, with the impact of an axial force (12) on the rotary element (4), the axial shiftability (14) of the rotary element (4) is limited by the support (16) of the first support surface (6) on the second support surface (10).

PROCESSING METHOD AND PLANT FOR WELDING METAL STRIPS
20230330728 · 2023-10-19 ·

A processing plant for metal strips (1) has a welding machine, a strip store downstream of the welding machine and a processing device downstream of the strip store. The metal strips are welded to form a continuous strip with the welding machine, which is stored in the strip store and output from there to the processing device. The metal strips are connected via diagonally extending weld seams. To join the weld seams, first the strip head (2) and the strip foot (3) of the metal strips are twisted and the two strips are connected by forming the weld seam. The weld seam extends only transversely to the transport direction (x) during the welding process. Finally, the strip head and the strip foot of the metal strips are twisted back again. As a result, the weld seam now extends diagonally to the transport direction (x).

Single shear for cutting and conveying multiple rolled sections

A shear for cutting and simultaneously conveying one or more pairs of rolling wires or bars includes a mobile diverter with at least two channels in each of which a wire or bar slides and at least two pairs of counter-rotating knives, each pair of which acts upon the wire or bar to produce cut segments of wires or bars. The cut segments of wires or bars are then conveyed by a conveying device including at least one pair of mobile elements that may be configured to move independent of each other and to be synchronized with each other and with the mobile diverter for facilitating insertion of each of the cut sections of wires or bars into an output channel of at least two pairs of output channels, each pair of output channels corresponding to one of the mobile diverters.

APPARATUS AND METHOD FOR PRE-FORMING A METAL STRIP FOR THE MANUFACTURE OF ROLL FORMED AND WELDED TUBES

An apparatus and method for pre-forming a metal strip, having an embossing tool and a strip edge chamfering tool, the embossing tool having an embossing roll having a cylindrical surface with a central embossing portion, and the strip edge chamfering tool having an edge chamfering roll having a recessed central section and side sections on each side of the central section, and an anvil roll, the edge chamfering roll and the anvil roll being configured to receive and pass the metal strip in a clearance formed between the rolls, the clearance having a reduced height in the side sections, which are located in a position where the longitudinal side edges of the metal strip will pass, so that the longitudinal side edges on each side of the metal strip, and on the embossed side of the metal strip become chamfered when being passed between the pair of rolls.

INTERMEDIATE BLANK CONNECTION SYSTEM FOR HOT-ROLLED STRIP HEADLESS ROLLING AND CONNECTION METHOD

The present invention relates to an intermediate blank connection system for hot-rolled strip headless rolling and a connection method, and belongs to the technical field of intermediate blank connection for strip steel headless rolling. The connection system and the connection method realize matching of an intermediate blank connection device and speed of a unit through a translation drive system. A mounting frame is used to provide support for cutting devices, and the cutting devices are divided into two groups arranged in the mounting frame to achieve clamping of a front slab and a rear slab respectively. Interlaced dovetail cutting edge structures are used to achieve cutting and ensure a good longitudinal stress state. Finally, a certain difference is set in sizes of width directions between cutting edges, to ensure that there is certain extrusion deformation in a process of forming dovetail cutting groove connection, and enhance a connection effect. At the same time of realizing a good intermediate blank connection effect finally, a structure of the connection device is greatly simplified, and investment and operating cost is reduced.

Cold rolling mill with alternative feed of a steel strip over two different paths

A first steel strip and a second steel strip (7) are rolled in succession in at least one roll stand (1) of a cold rolling mill. A rolling pause, in which no steel strip is rolled, is provided between the rolling of the first and the second steel strip (7). The first steel strip is fed over a first path starting from a first pay-off reel (2), and the second steel strip (7) is fed over a second path starting from the first pay-off reel (2), or from a second pay-off reel different from the first pay-off reel (2). The first steel strip is not heated as it is fed to the rolling mill (1), whereas, by contrast, the second steel strip (7) is heated. The second path is longer than the first path.
