  2. Drawer slides roll forming machine - Wikipedia

    en.wikipedia.org/wiki/Drawer_slides_roll_forming...

    The basic production flow of drawer slide machine is roll forming, punching, and cut off to length. Processes of drawer slides roll forming is a continuous cold rolled steel strip passing through a plurality set of upper and lower shaped rollers, and then punching, embossing, straightening, and cut off to length. Straightening is an important ...

  3. Roll forming - Wikipedia

    en.wikipedia.org/wiki/Roll_forming

    Roll forming, also spelled roll-forming or rollforming, is a type of rolling involving the continuous bending of a long strip of sheet metal (typically coiled steel) into a desired cross-section. The strip passes through sets of rolls mounted on consecutive stands, each set performing only an incremental part of the bend, until the desired ...

  4. Roof seamer - Wikipedia

    en.wikipedia.org/wiki/Roof_seamer

    In 1976, a German immigrant and inventor, Ewald Stellrecht, [1] helped develop an early version of a metal roof panel portable roll forming machine in Exton, PA. From this a version of the roof seamer was also created. Since that time, great strides and innovations have been made in the development of roof seaming machines.

  5. Structural shape rolling - Wikipedia

    en.wikipedia.org/wiki/Structural_shape_rolling

    Cross-sections of continuously rolled structural shapes, showing the change induced by each rolling mill. Structural shape rolling, also known as shape rolling and profile rolling, [1] is the rolling and roll forming of structural shapes by passing them through a rolling mill to bend or deform the workpiece to a desired shape while maintaining a constant cross-section.

  6. Rolling (metalworking) - Wikipedia

    en.wikipedia.org/wiki/Rolling_(metalworking)

    Rolling schematic view Rolling visualization. In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property.

  7. Plate rolling machine - Wikipedia

    en.wikipedia.org/wiki/Plate_rolling_machine

    The pinching roll holds the plate. Three-roller machines (variable pitch aka variable geometry) have one pressing top roll and two pressing side rolls. The three-roll variable pitch works by having all three rolls able to move and tilt. The top roll moves in the vertical plane and the side rolls move on the horizontal plane. When rolling, the ...

  8. Roll bender - Wikipedia

    en.wikipedia.org/wiki/Roll_bender

    Roll bender machine. A roll bender is a mechanical jig having three rollers used to bend a metal bar into a circular arc. The rollers freely rotate about three parallel axes, which are arranged with uniform horizontal spacing.

  9. Tandem rolling mill - Wikipedia

    en.wikipedia.org/wiki/Tandem_rolling_mill

    Off-line work roll pre-heaters use an electrical coil to induce currents in the work roll inserted through the coil. These currents heat the work roll and create a thermal camber before the roll is placed into the mill. This reduces the problems experienced when rolling the first few coils after putting cold work rolls into the mill.
