Abstract
A method of and an apparatus for the cropping of leading or trailing end portions of rolled workpieces in which downstream of the rotary shear, a diverter is provided and upstream of the shear there is a rocker guiding the workpiece to the shear and having a cardan type articulation allowing pivotal movement of the rocker about horizontal and vertical axes selectively.
Claims20
A method of cropping ends of elongated longitudinally displaced traveling rolled metal workpieces, comprising the steps of:
- (a) guiding successive elongated longitudinally displaced traveling rolled metal workpieces along a roll line toward a shear along a rocker upstream of said shear, said rocker having a cardan joint at an upper end thereof and being provided with means for raising and lowering a downstream end of the rocker about a horizontal axis with means for swinging said rocker about a vertical axis;
- (b) swinging said rocker about at least one of said axes to deflect said workpieces selectively onto a predetermined path out of said roll line in response to measurement of displacement of said workpiece;
- (c) at said shear, cropping at least one end portion of each of said workpieces to sever the respective end portion from a body of the respective workpiece and in response to the measurement of displacement of said workpieces;
- and
- (d) downstream of said shear intercepting said end portion with a fixed diverter diverting said end portion from said line while lifting the body of the respective workpiece over said diverter back along said line.
An apparatus for cropping ends of elongated longitudinally spaced travelled rolled metal workpieces comprising:
- a rolling line along which successive elongated longitudinally displaced travelling rolled metal workpieces are guided;
- a shear along said line for cropping selectively leading ends and trailing ends of said workpieces;
- a rocker along said line upstream of said shear and provided with a cardan joint at an upstream end of said rocker defining a pivot about a horizontal axis and about a vertical axis for said rocker;
- a diverter downstream of said shear and formed with a separating wedge;
- at least one position detector for producing signals representing a position of at least one of said shear and said rocker;
- electronic control means responsive to said signals for operating said rocker and said shear for cropping at least one end of a workpiece displaced along said line;
- and
- means at least in part rendered effective by displacement of said rocker about one of said axes for removing a cropped end of a workpiece from said line.
