BUTTING METHOD FOR BROAD METALLIC STRIPS

摘要

PURPOSE:To improve the accuracy of a butt groove and welding by running a rotary grinding body along the weld line and cutting metallic strips. CONSTITUTION:A pair of roller 4 are attached to a frame body 5 and are engaged with a traveling rail 1. A driving motor 6 is disposed to the body 5 and the rotary grinding body 2 is connected to the motor 6. The preceding and succeeding broad metallic strips 3 are run on the traveling rails and are conveyed to a cutting position where the strips are held and fixed by a clamper. The body 2 is then run to cut the respective ends of the strips 3. The cut faces are held fixed and are formed by the grinding body 2 such as grinding wheel or grinder and therefore the high-accuracy working coinciding with the weld line is made possible. Since the weld groove is formed with high accuracy, the accuracy of laser welding is improved as well.
