Abstract

PURPOSE:To manufacture a light and cheap titled clamp plate easily by press working a semicircular arcuate piece formed by cutting a round steel tube and forming sleeves on both ends and reinforcing rims on both edges leaving an arcuate embracing part in the intermediate part. CONSTITUTION:A round steel tube 1 of specified diameter is splitted at a diameter line 2 into two semicircular tubes 2, 3 in the lengthwise direction, and the tube 3 is cut to a specified width along planes 4 perpendicular to the lengthwise direction, and many semicircular arcuate pieces 5 are formed. Next, the semicircular arcuate piece 5 is press worked in one process to bend the both ends to outside and flatten to form sleeves 7 leaving an arcuate embracing part 6 in the intermediate part. At the same time, both edges are bent to inside to form reinforcing rims 8. Holes 9 for joining are made next on the sleeves 7, 7 to complete a clamp plate for joining a cylindrical tube.
