Technology Of 72-Tooth Ratchet Socket Wrench

The technology of the 72-tooth ratchet socket wrench

1. The 72-tooth ratchet socket wrench is a commonly used tool mainly used for tightening and loosening screws and nuts. It consists of a set of interchangeable sockets and a handle with a ratchet mechanism to accommodate screws and nuts of different sizes.

2. The manufacturing process of the tool mainly includes the following aspects:

1） Material selection: In order to ensure the safety and service life of the tool, it is necessary to select high-strength and high-wear-resistant materials as raw materials for manufacturing. Common materials are chrome-molybdenum alloy steel, chrome steel, etc.

2）Processing process: The manufacture of precise sleeves and handles requires multiple precise processing processes. The first is CNC turning processing, the raw material is processed into the shape and inner hole of the sleeve, then after grinding, heat treatment, and other processes, and finally the surface treatment.

3）Manufacture of the ratchet mechanism: The ratchet mechanism is processed at the part where the handle and the sleeve are connected, which can provide one-way tightening and loosening force, and further improve the performance of the tool.

4）Assembling and testing: At the final stage of the production process, assembly and testing of the sleeve and handle are required. Including testing the tightening strength and precision of the sleeve, the power transmission of the handle, and the reliability of the ratchet mechanism, etc.

3. In conclusion, the 72-tooth ratchet socket wrench is a high-precision and high-demand tool with a wide range of applications, and its manufacturing process requires various precision machining. Only an excellent manufacturing process can produce high-quality tools and improve the performance and service life of tools.
