IPC: B21B27/02
Filed: 1989-03-03
Abstract: PURPOSE:To prevent the damage of projections by lapping up by working grooves to work rolls in the axial direction thereof and setting the angle on a bite side larger than the angle on a release side in order to prevent the shape collapse of the grooves by the lapping-up of the work rolls. CONSTITUTION:The grooves are worked to the work rolls in the axial direction thereof at a certain length pitch without penetrating the grooves through the rolls to prevent the shape collapse by the lapping up of the work rolls. Since the already roll-molded projections exist at the time of parting the steel plate surface from the roll surfaces, the angle alpha0 of the wall surfaces of the roll grooves is set smaller than the angle alpha1 on the bit side in order to prevent the contact of the peak parts of the projections with the wall surfaces of the roll grooves and the consequent deformation. The thick steel plate with the projections which is entirely free from the damage of the projections by the lapping-up of the work rolls is obtd. in this way. The excellent production process which assures the smooth contact with back up rolls, produces no impact and abnormal noises and do not show the abnormality of patterns, etc., on the roll surfaces is obtd.
