Introduction

The steel bar sleeve working wrench is a specialized tool used in the construction of mechanical connection of steel bars, for tightening or loosening the steel bar sleeves. Its core function is to ensure that the connection between the sleeve and the steel bar reaches the designed strength and tightening requirements by precisely controlling the torque. It is a key equipment for guaranteeing the quality of mechanical connection of steel bars. The following provides a detailed analysis from aspects such as type, parameters, and operation specifications:

Core Function and Role

When connecting steel bar sleeves (such as straight thread sleeves, extrusion sleeves, etc.), a specific torque needs to be applied through the wrench to make the inner wall threads of the sleeve tightly engage with the end threads of the steel bar (or the extruded part) to form an axial fixation. The core functions of the wrench include:

1. Controlling the tightening torque to avoid looseness (insufficient connection strength) or tightness (deformation of the sleeve / steel bar);

2. Ensuring the coaxiality of the steel bar and the sleeve to reduce eccentric loading;

3. Adapting to different specifications of sleeves to achieve standardized construction.
