Clamping apparatus for welding equipment

Abstract

Abstract PURPOSE: To simplify the structure by eliminating the intermediate clamping beams which moves vertically, by making an arrangement so that clamp beams selectively absorb under vacuum upper and lower pass metallic plates which are carried to both sides of guide table by leaving intervals and cut simultaneously. CONSTITUTION: Vacuum absorbing pads 11 a and 11 b are assembled into clamping beams 3 and 4, and the vacuum pads 11 a and 11 b are connected to vacuum pumps 12 a and 12 b , respectively. When the shear position of a plate 14 of upper and lower pass metallic plates 13 and 14 is to be set, the plate 13 waiting on a guide table 2 is moved to a location where the plate touches one side of shear blades 8 and 9. Then, both the plates are fixed with beams 3 and 4 and , at the same time, one side of the plate 14 is fixed with clamping beams 6 and 7. When the fixing with beams 3 and 4 is completed, the plate 13 is absorbed to the beam 3 with the pad 11 a , and, after the plates 13 and 14 are cut simultaneously, the scrap tail of the plate 14 is pulled out by releasing the beam 3. Then, the beam 3 and the plate 13 are lowered again and fixed between the beam 4. After the cut edge of both the plates is superposed a seam welding is performed. After the welding is completed, the pump 12 a is stopped and the plate 13 is released. COPYRIGHT: (C)1982,JPO&Japio
