Title: Production of fuel tank support for vehicle
Inventor: TANIZAWA TAKAO
IPC: B62D25/00
Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of wrinkles on an inward bent face by pressing a hat shaped ceiling part from inside with a press die and expanding both sides of a 90 deg. bent part in the width direction when the fuel tank support for vehicle to support/fix to a vehicle body is produced from a metal strip formed to a hat shape in its cross section. SOLUTION: Relief recessed parts 1b are arranged to both sides of a pressing face 1a of a bending press lower die 1 of a bent support 3, a press projecting part 2a corresponding to the lower die pressing face 1a is arranged to an upper die. By placing a strip plate, which is formed to the hat shaped in cross section beforehand by pre-working, on the lower die 1 and descending an upper die, the 90 deg. bent part 3a of the support 3 is formed by pressing the ceiling part of a hat part from inside by a pressing face 1a. At this case, a width of the bent part 3a in both directions is not restrained by the relief recessed parts 1b and expanded, as a result, a wrinkle is not generated both bending parts and flat state is maintained. A whole hat shape 3b except the 90 deg. bent part 3a of the support 3 produced has a diameter of the pre-working shape.

Title: Crater treating method for circular welding equipment
Inventor: HIGASHIJIMA SUMIO
IPC: B23K9/02
Filed: 1987-10-07
Abstract: PURPOSE:To prevent defective welding by rotating a torch from a prescribed point to weld the periphery of a work and rotating the torch reversely after attaining a prescribed point and decreasing a welding current gradually to carry out treatment of a crater part satisfactorily. CONSTITUTION:Inner and outer pipes 1 and 2 are joined together and those peripheries are welded while rotating the torch 3. With the titled circular welding equipment, the torch 3 starts welding from a point P1 and welds the peripheries of the pipes 1 and 2 while rotating in the arrow direction. When the torch 3 again attains the point P1 after rotating one time, the torch 3 is rotated reversely in the opposite direction to the arrow direction. At the same time with this, the welding current decreases gradually. By this method, even when the torch can not be moved more than one rotation, the crater part is welded satisfactorily and to occurrence of defective welding such as a leak is prevented without causing heat concentration on the crater part.
