Embodiment Construction
[0019] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0020] The invention provides a device for bending stirrups on the main reinforcement of a square steel cage and welding the stirrups. The device for bending and welding the stirrups on the main reinforcement of the square steel cage comprises: a frame 1 and an insulating pad 16 arranged on The lower electrode 15 on the frame 1, the cross section of the lower electrode 15 is square;
[0021] It also includes four main ribs, namely: the upper left main rib 14a, the upper right main rib 14b, the lower left main rib 14c and the lower right main rib 14d; Corner curved edges. That is, the four main ribs coincide with the arc surfaces at the four corners of the lower electrode 15 .
[0022] It also includes a steel bar 13 pre-bent into a stirrup 13a. The steel bar 13 is perpendicular to the main bar and is supported on the left upper main bar 14a and the rig...

The invention discloses a device for bending and welding a stirrup on main reinforcements of a square steel reinforcement cage. The device comprises a rack and a lower electrode with a square section. The four main reinforcements are attached to the four corners of the lower electrode. A steel bar is perpendicular to the main reinforcements and is supported on the upper main reinforcements. A first pair of bending and welding mechanisms is arranged in the positions, above the main reinforcements and in the two diagonal extending lines of the main reinforcements, of the rack, and a second pair of bending and welding mechanisms is arranged in the positions, below the main reinforcements and in the two diagonal extending lines of the main reinforcements, of the rack. Each bending and welding mechanism comprises a bending mechanism body and a welding mechanism body. According to each bending mechanism body, a bending base is mounted on a piston rod of a bending air cylinder, a pair of bending plates is hinged to the bottom of the bending base, and a bending roller is hinged to the bending plates. According to each welding mechanism body, an upper electrode is connected to a piston rod of a welding air cylinder in an insulating mode. The device has the beneficial effects that screw rods are adjusted by adjusting hand wheels so as to drive sliding bases with the bending and welding mechanisms to move, and therefore the bending and welding mechanisms are adapted to bending and welding of stirrups of square steel reinforcement cages of different specifications; the device has the advantages of being compact in structure, high in production efficiency, small in occupied space and low in cost.
Description
technical field [0001] The invention relates to a device for bending stirrups on the main reinforcement of a square reinforcement cage and welding the stirrups. Background technique [0002] The square reinforcement cage is formed by welding multiple square stirrups at intervals on four main reinforcements. In the prior art, the square reinforcement cage is manufactured step by step by hand, that is, a plurality of square stirrups are manually bent in advance, and then the square stirrups are welded to the outer edges of the four main bars with square cross-sections at set intervals. In the prior art, the hand-welded square reinforcement cage adopts stirrup bending and welding to be carried out step by step, which has the defects of poor quality, slow speed and low efficiency. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned deficiencies in the prior art, provide a kind of on the main bar of square steel bar cage, steel...
