Description

Technical Field

[0001] The utility model relates to the technical field of steel cage processing equipment, in particular to an automatic feeding device for a steel cage forming machine. Background Art

[0002] The main function of the steel cage is the same as the stress of the longitudinal steel bars of the column. It mainly plays a tensile role. The compressive strength of concrete is high but the tensile strength is very low. It plays a restraining role on the pile concrete so that it can withstand a certain axial tension.

[0003] At present, in the process of building construction, it is often necessary to tie a steel cage on site. In the prior art, the steel cage is generally composed of four main bars forming a rectangular structure and a number of secondary bars fixed to the outside of the four main bars by tying wires. When the steel cage is tied on site, the main reinforcement frame of the rectangular structure usually needs to bend the ends of the straight steel bars by a bending machine or weld two semi-bent steel bars into a rectangle. In the process of arranging the steel bars, all the transverse and longitudinal bars need to be manually lifted and placed on the reinforcement platform. This process is heavy physical repetitive labor with low efficiency and high labor intensity, which greatly affects the production efficiency of the steel cage and cannot meet the needs of mass production of the steel cage. In addition, the quality of the processed main reinforcement frame products is uneven, which can easily affect the construction progress.

[0004] Therefore, developing a new automatic feeding device for steel cages and changing the traditional structural form not only has urgent research value, but also has good economic benefits and industrial application potential. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the purpose of the utility model is to provide an automatic feeding device for a steel cage forming machine, which adopts automatic feeding to replace manual feeding, reduces the labor intensity of workers, and improves the production efficiency of the steel cage.
