This topic is the integration of hexagonal wrench and die design.
Traditional wrench only one size, to simultaneously access different hex nuts, equipped with all the different dimensions of a wrench, very inconvenient. Existing combined, some structure is more complex, there are several parts to connect, to replace the different dimensions of parts, operate. This design from structural break with tradition, according to the country as a wrench, hex nuts standard, the eight different sizes of Hexagon wrench into one, not only light weight, easy to carry and easy to use, from the selection and arrangement of the tool, suitable for all kinds of works and household use.
Wrench design uses the standard GB4388 ~ GB4393, use AutoCAD to implement integrated wrench design and molded parts design, analysis units forming quality and finish typing surface design and product design and tooling, secondary to the necessary calculation, the digital design and theory of computation, improve product design and mold design as to the accuracy, quality product prototyping.Keyword: integrated wrench;Die-casting mold; AutoCad
