Sheet metal blank

A process includes flexible rolling of a strip made of a metallic material, wherein a thickness profile with different sheet thicknesses along the length of the strip is produced such that successive regions of the flexibly rolled strip each correspond to a target thickness profile of a sheet metal blank to be cut out of same; determining a measured thickness profile of a plurality of successive regions of the strip; calculating a target position in the strip for a sheet metal blank to be cut out of the strip depending on the generated measured thickness profile of at least two successive regions of the strip; cutting the flexibly rolled strip by at least one cutting device along the target position for producing the sheet meal blank. A plant is further provided for producing a sheet metal blank.

Pulse current assisted uncanned rolling method for titanium-TiAl composite plates

The present disclosure provides a pulse current assisted uncanned rolling method for titanium-TiAl composite plates, including the following specific steps: 1. preparing titanium alloy sheets; 2. preparing TiAl alloy sheets; 3. uncanned lay-up; 4. pulse current assisted hot-rolling; 5. separation and subsequent processing, thus getting the titanium-TiAl composite plates. The composite plates are of good quality on the surface without oxide layer shedding, no cracks at the edges and the ends, with uniform and fine microstructures, good bonding interface and excellent mechanical properties.

WHEEL ENGRAVING EQUIPMENT

The present application discloses wheel engraving equipment, which includes a lower lifting system, lower flange engraving systems, inner rim engraving systems, a wheel positioning and clamping system, an upper lifting and rotating system, a synchronous clamping and rotating system and the like.

Apparatus and method for trimming a side of steel plate

A side trimming apparatus including a cutting unit which is installed on at least one side of a steel plate being transferred and trims a side of the steel plate by mechanical cutting and a laser processing unit which is installed in front of the cutting unit and emits a laser beam to a portion of the steel plate to be cut to form a groove at the portion to be cut or preheat the portion to be cut, and a side trimming method using the same are provided.

Changes enabling the elimination of processes for a torsion bar

In one aspect of the invention, a torsion bar assembly is provided. The assembly includes a first shaft having a first bore, a second shaft having a second bore, the second shaft operatively coupled to the first shaft, and a torsion bar positioned within the first and second bores. The torsion bar includes a splined first end having a first diameter extending to a first end face having a diameter generally the same as the first diameter, a splined second end having a second diameter extending to a second end face having a diameter generally the same as the second diameter, and an active diameter extending between the splined first end and the splined second end. The torsion bar is fabricated from a material having a hardness greater than 45 Rockwell C-Scale.

Method for processing a plate workpiece

A workpiece made of plate is subjected to a treatment which locally modifies its magnetic permeability. Subsequently, the magnetic permeability of the workpiece is examined locally resolved by a probe in order to find at least one surface region which is suitable for intended processing, and the processing is performed locally limited to the selected region.

HIGH PRODUCTION QUALITY ROUND WIRE ROD USING A SLIT ROLLING PROCESS

Disclosed within is a slit section pass formation unit having a pair of rolls and a de-ribbing means, where the pair of rolls has a roll profile configured to produce a pair of slit rods with symmetrical dimensions, the pair of slit rods connected via a rib, and the de-ribbing means to remove the rib in its entirety forming a first slit rod and a second slit rod.

HOT-ROLLED STEEL SHEET AND METHOD FOR MANUFACTURING SAME

A hot-rolled steel sheet not exceeding a coil opener allowable load during unwinding includes a steel sheet cut in unsteady portions at its longitudinal head and tail ends in a cutting step after a rough rolling step, having a width of 1,200 mm to 2,300 mm, a thickness of 13 mm to 25.4 mm, and at least an API standard X65-grade strength, and used in a state of being unwound after having been wound around a coil. A longitudinal end corresponding to the unwinding start includes a portion at its widthwise center recessed inwards in the longitudinal direction with respect to its two widthwise ends, the two widthwise ends projection sizes with respect to the recessed portion at the widthwise center are 20 to 295 mm, and the sum of the widths of projecting portions at the two widthwise ends is set to to of the sheet width.

EMERGENCY STOP CONFIGURATION FOR IRONWORKER

One aspect is a hydraulic ironworker system having a hydraulic ironworker configured with hydraulic power to deliver controlled force to metal workpieces. An accessory tool is coupled to the hydraulic ironworker via a harness assembly and configured to receive the hydraulic power from the hydraulic ironworker. A remote pushbutton assembly is removably coupled to the harness assembly and configured to control hydraulic power from the hydraulic ironworker to the accessory tool and further configured with an emergency stop button that, when actuated, disables all power to the hydraulic ironworker system. A safety plug assembly is configured to alternately couple to the harness assembly in place of the remote pushbutton assembly. Power to the hydraulic ironworker system is disabled until one of the remote pushbutton and safety plug assemblies is attached on the harness assembly.

Method and apparatus for producing flat metal products

Method for the production of flat metal products, in particular coils of strip, in endless and/or semi-endless mode, in which a metal product is continuously fed to a rolling mill consisting overall of at least 4 stands. The rolling stands are, in sequence, roughing stands, and finishing stands. It is provided to perform a flying gauge change of the metal product exiting from the rolling mill.
