Description

Technical Field

[0001] The utility model relates to the technical field of steel cage manufacturing, in particular to an inner stirrup welding device. Background Art

[0002] At present, the inner reinforcing stirrups of circular steel cages are all made of threaded steel bars, and are fixed by spot welding at four positions of the intersection of the inner reinforcing stirrups and the main bars, thus forming the skeleton of the steel cage. This overlap and welding fixation method of the inner reinforcing stirrups and the main bars has the following disadvantages: 1. When the circular inner reinforcing stirrups intersect the circular main bars vertically, the intersection of the two is the intersection of two lines, that is, the intersection is a point, and a point can only be fixed by spot welding. The quality of the spot weld is not easy to control. When the quality of the spot weld is poor, it affects the quality of the steel cage; 2. When making the inner reinforcing stirrups of threaded steel, the specification requires that the two ends be connected by single-sided welding 10 times D and double-sided welding 5 times D. The weld is very long, which costs a lot of welding rods and workers, and the production cost is high; 3. The threaded steel is fixed in length. Whether it is 9 meters or 12 meters, when making the inner reinforcing stirrups, the remaining part of each threaded steel is wasted quite a lot, and the threaded steel cannot be used well. Secondly, the welding of internal reinforcing stirrups and main bars is usually achieved through manual welding, which has low welding efficiency and the quality of different welding points cannot be kept consistent.
