Abstract
Method for forming tubular segments, wherein a metal strip is or a series of metal strips is pressed into a tubular or truncated conical shape, such that opposite longitudinal ends of the strip or strips meet, forming at least one seam, where after the seam is welded, joining the meeting ends together, wherein at least after welding the cross sectional profile of at least part of the segment is measured, at least at and/or near said welded seam or seams, and data of said measurement is fed into a control unit, where after a press is operated by the control unit based on said data, adjusting the cross sectional profile of the segment, at least at the or each seam.
Claims25
Method for forming tubular segments comprising:
- pressing a metal strip or a series of metal strips into a tubular or truncated conical shape, such that opposite longitudinal ends of the strip or strips meet, forming at least one seam;
- welding the seam, joining the meeting ends together;
- after welding, measuring the cross sectional profile of at least part of the segment at least at and/or near said welded seam or seams;
- feeding data of said measurement into a control unit;
- after the data of said measurement is fed into the control unit, a press is operated by the control unit based on said data, adjusting the cross sectional profile of the segment, at least at the seam or at each seam;
- and
- adjusting said cross sectional profile of the segment with a roller press.
Press system for forming a tubular or truncated conical metal segment, comprising:
- at least a press and a control unit for controlling the press, wherein the system further comprises a measurement tool for measuring at least part of a cross sectional profile of the tubular or truncated conical segment, which measurement tool is connected to the control unit for feeding measurement data into the control unit, and wherein the control unit comprises at least an algorithm for controlling the press, based on at least said measurement data, wherein the press is a roller press.
Computer program product comprising:
- a computer readable program for control of a pressing process for forming tubular or truncated conical metal segments, wherein the program is designed for receiving measurement data pertaining to a cross sectional profile of at least part of such segment and controlling a roller press for adjusting said profile.
