In this way, the welding process of the lower half of the steel reinforcement cage is completed. Then, the positioning top die 3 can be temporarily and detachably installed on the plurality of positioning bottom dies 2 through the connecting assembly 4. At this time, a plurality of main cables can be taken and placed in the steel reinforcement positioning grooves 5 on the positioning bottom dies 2 in sequence. Then, the main cables on the positioning top die 3 are combined with the main cables on the positioning bottom die 2 to form a circular ring, and the arrangement of the main cables of the entire steel reinforcement cage is completed. At this time, the point-welding between the main cables on the positioning top die 3 and the plurality of circular reinforcing bars is completed, so that the steel reinforcement cage is preliminarily formed by welding. Finally, the assembly of the plurality of positioning top dies 3 on the plurality of positioning bottom dies 2 is released through the connecting assembly 4, and the plurality of positioning top dies 3 are taken out of the steel reinforcement cage, thereby completing the main reinforcement 19 processing task of the steel reinforcement cage. In use, the positioning precision is high, the operation is convenient, the processing cost is low, the stability is good, the positioning device can be recycled, and no other auxiliary devices are needed. The main reinforcement 19 can be placed in the steel reinforcement positioning grooves 5 on the positioning top die 3 and the positioning bottom die 2 according to needs, and the steel reinforcement cage can be processed according to different specifications such as the interval, diameter and number of the main reinforcement 19 of the steel reinforcement cage, so the practicality is high. In addition, during the welding process of the steel reinforcement cage, a plurality of positioning devices are arranged at the steel reinforcement processing position and are fixed on the ground surface at certain intervals, so that the steel reinforcement cage does not need to be moved during the entire processing process. Under the premise of ensuring the processing precision, the processing efficiency of the steel reinforcement cage can be greatly improved.

[0031] Optionally, the positioning top die 3 comprises a first arc-shaped positioning plate 6 and a second arc-shaped positioning plate 7.
