Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] A method for processing an "8"-shaped grid, characterized in that it comprises the following steps:

[0016] a. If figure 1 As shown, adopt the existing steel bar bending equipment to bend the steel bar into a rectangle, and weld the ends to form a rectangular steel bar with a closed structure;

[0017] b. If figure 2 As shown, the two long sides of the rectangular steel bars are horizontally stamped with special stamping equipment to form "8" shaped steel bars;

[0018] During processing, special stamping equipment can be used to match the mold. First, the piston rod of the special stamping equipment is recovered to the shortest stroke. At this time, the rectangular steel bar is installed on the backing plate, the hydraulic pump is started, the piston starts to work, and the main formwork is pushed forward. The positioning pins cont...

Abstract

The invention discloses a method for machining a '8'-shaped grid. The method is characterized by comprising the following steps of: a. bending a reinforcing steel bar into a rectangle, and welding the ends of the reinforcing steel bar to form a rectangular reinforcing steel bar with a closed structure; b. horizontally stamping the two long sides of the rectangular reinforcing steel bar to form a '8'-shaped reinforcing steel bar; and c. vertically stamping the middle part of the '8'-shaped reinforcing steel bar so that the middle part of the '8'-shaped reinforcing steel bar sinks to form an inverted trapezoidal concave part. The method has the beneficial effects of simpleness in operation and process, needing fewer welding joints during mechanical operation, guaranteeing the shape of the '8'-shaped vertical surface, needing less labor force, realizing assembly line work, improving the machining efficiency and saving cost.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a processing method for an "8"-shaped grid. Background technique [0002] At present, the initial support grid steel frame of the tunnel is an "8"-shaped structure, which is difficult to process and manufacture. The traditional manufacturing method is: divide the "8"-shaped grid into 4 parts for cutting, and then The planar shape is bent out on the steel bar bending machine, and then welded together to form an "8"-shaped structure. This traditional production method has low work efficiency, cannot guarantee the shape of the "8"-shaped facade, cannot realize streamlined operation, and is difficult to guarantee the quality. Contents of the invention [0003] In view of the shortcomings of the above-mentioned prior art, the object of the present invention is to provide a processing method for "8"-shaped grille, which can ensure the shape of the "8"-shaped facade, ...
