Abstract

The invention relates to the technical field of civil air defense doors, in particular to a manufacturing method of a civil air defense door frame. The manufacturing method is used for manufacturing the door frame formed by assembling two longitudinal steel angles, an upper steel angle and a lower steel angle. The manufacturing method includes the following steps that the four steel angles are derusted by a civil air defense equipment derusting device; locking holes and rib penetrating holes are stamped in the two longitudinal steel angles; compression strips are welded to the four steel angles; the four steel angles are straightened one by one through a straightening machine; the whole door frame is assembled by the four steel angles and an upper hinge base and a lower hinge base are welded on a welding platform; and quality inspection and paint brushing treatment are completed. According to the manufacturing method of the civil air defense door frame, by the adoption of the technicalscheme, the technical problems that an existing manufacturing process of the civil air defense door frame is complex, the welding process is high in requirement, and the quality is not stable are solved.

Description

technical field [0001] The invention relates to the technical field of civil air defense doors, in particular to a method for manufacturing a civil air defense door frame. Background technique [0002] "Civil air defense project" is a civil air defense project, also called a civil air defense fortification. basement. [0003] The civil air defense door is a more important part of the civil air defense equipment. The civil air defense door is composed of a steel structure civil air defense door frame, door leaf and accessories welded. [0004] Such as figure 1 As shown, the composition of the civil air defense door frame is composed of four angle steels, upper, lower, left and right, an upper hinge base and a lower hinge base. The door frame locking hole and reinforcement hole cutting system completes the cutting of the locking hole and the reinforcement hole of the two longitudinal angle steels; then splices the two longitudinal angle steels and the two transverse angle s...
