Scope

Scope: This document specifies the models and specifications, requirements, test methods, inspection rules, marking, packaging, transportation, and storage of thick blades for shearing machines. This document is applicable to blades for shearing machines used to cut metal materials with a thickness of 25 mm to 60 mm (hereinafter referred to as "blades"). Main technical content: This standard specifies the materials, hardness, machining requirements, and test methods for thick blades for shearing machines (hereinafter referred to as "blades"). The technical content of this standard is divided into 7 chapters, including: scope, normative references, models and specifications, requirements, test methods, inspection rules and marking, packaging, transportation, and storage. (1) Regarding "Scope": The market demand for shearing blades for thick metal plates is large, especially in steel rolling production enterprises. China is a major steel producer, and to meet market demand, this standard has been developed. This standard is applicable to blades for shearing metal materials with a thickness of 25 mm to 60 mm. (2) Regarding "Models and Specifications": The standard specifies the models and common specifications of blades to better interpret the technical requirements of the standard. (3) Regarding "Materials": Based on the working characteristics of blades, it is stipulated that the materials used for manufacturing blades should preferentially adopt materials with good comprehensive performance contained in GB/T 1299, and the chemical composition and mechanical properties of the materials should comply with the requirements of GB/T 1299. (4) Regarding "Hardness": To ensure the wear resistance and shearing performance of blades, the hardness of blades is stipulated. (5) Regarding "Machining": To ensure the working accuracy of blades, the dimensional accuracy, shape and position tolerances, and surface roughness of blades are stipulated in machining.
