More Information
Summary:The utility model discloses a star-shaped frame welding and assembling mould for dry type hollow parallel reactors, which comprises a circular bottom plate and a fixing hinge pin. The fixing hinge pin is arranged at the circle center of the bottom plate, radial fixing grooves are disposed on the bottom plate from the circle center to the edge of the bottom plate, the quantity of the fixing grooves is identical to that of star frame arms on a star-shaped frame, and positions of the fixing grooves correspond to those of the star frame arms. Welding accuracy of the star-shaped frame is guaranteed, welding deformation can be reduced after welding, required flatness of a reactor coil when the reactor coil is clamped is realized, the quality of the appearance of a reactor is effectively improved, and distortion of the reactor is decreased.
