Description

technical field

[0001] The invention relates to an electric connecting tool used in the construction industry for threaded connection of steel bars and connecting sleeves, and belongs to the technical field of steel bar connecting equipment. Background technique

[0002] The mechanical connection of steel bars is a thick steel bar connection method in the construction industry. When connecting, two steel bars are connected using a connecting sleeve. The connection between the steel bar and the connecting sleeve is through extrusion deformation, wedging between threads, etc. The form is realized. The main ways of connection are: radial and axial extrusion connection (cold extrusion connection), taper thread connection, upsetting straight thread connection, rolling straight thread connection and other forms. The connection between steel bars and connecting sleeves has the advantages of reliable joint performance, stable quality, not affected by climatic conditions, simple pro...
