Description

Technical Field

[0001] This invention relates to the field of rebar connection and processing technology, and more particularly to a rebar threading machine. Background Technology

[0002] Rapid connection of reinforcing bars is a new requirement that has emerged in the construction process in recent years. Achieving rapid connection of reinforcing bars can significantly shorten the construction cycle and improve economic efficiency.

[0003] Currently, a common method for connecting reinforcing bars is the straight thread sleeve connection. This method involves threading the end of the reinforcing bar to form an external thread, then threading the sleeve to form an internal thread, and finally connecting the reinforcing bar and sleeve via these threads. However, existing straight thread sleeve connection devices are generally quite simple and cannot achieve continuous connection, significantly impacting production efficiency and project progress. Furthermore, they have poor tolerance for rebar misalignment, leading to occasional deviations in the installation position of some rebars. Because the straight thread sleeve requires precise alignment, the connection is difficult, resulting in poor consistency of the manufactured rebar connectors; moreover, continuous production is not feasible, making it unsuitable for large-scale production.

[0004] In conclusion, there is an urgent need for a rebar threading machine to solve the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a rebar threading machine. This machine solves the problems of conventional straight thread sleeve connection devices, which are generally too simple and cannot achieve continuous straight thread sleeve connections, significantly impacting production efficiency and project progress.
