The shearing machine uses a moving upper blade and a fixed lower blade, and uses a reasonable blade gap to apply shearing force to metal plates of various thicknesses, so that the plates can be broken and separated according to the required size.
Shearing machine working principle and structure Shearing machine is often used to cut the straight edge of the blank. The shearing process should be able to ensure the straightness and parallelism requirements of the shear surface of the sheared sheet, and minimize the distortion of the sheet to obtain high-quality workpieces.
Shearing machine is a kind of forging machinery, and its main function is the metal processing industry.
Carbon-bonded tool steel, low-alloy tools, alloy tool steel, etc. are often selected materials for shear blades. Carbon-bonded steel generally uses 65, 75 steel, T8, T10 and other materials. The heat treatment hardness of the blade produced by this material is HRC57— Within the range of 59 degrees, it is suitable for the recovery and shearing of ordinary low-carbon cold-rolled plates, ordinary A3 plates and waste materials. This feature is low cost and suitable for product prices. The commonly used materials for the blades of low-alloy tool steel are: 6Crw2sI, Cr5,o, 9CrSi, Cr12MoV, etc. The heat treatment hardness of the blade is within the range of HRC58-62 degrees. It is specially cut stainless steel, suitable for hot-rolled plates, stainless steel, medium and thick plates. Cut. The shear blade materials of alloy tool steel are: 4Cr5MoSiV1 (H13K), 7Cr7Mo2V2Si9 (LD), W6Mo5Cr4V2(6542)H13, etc. The blades of this material are used for hot-rolled steel billets, hot-shearing medium and thick steel plates, etc. This feature is high temperature resistance and not easy to anneal. The hot-rolling and hot-shearing process of Tiangang Works is used. It is suitable for various mechanical industries such as automobile, shipbuilding, electrical, engineering, meal, machinery industry, metallurgical industry, electronics industry, aerospace industry, and machinery manufacturing.
has a history of several years in the history of industry, and nowadays the shearing machine has become a common equipment in the machinery industry. However, in actual work, the purchasing departments of various companies often do not know how to choose a good and suitable shear blade. It is believed that the better the material, the better the use of the shear blade. In fact, the material used of the shear blades depends on the plates cut by the shears: T 10, Cr5Mo, 9CrS i shear blades are suitable for cutting ordinary A3 ordinary low-carbon cold-rolled plates and scraps. Recycling shear, this feature is low cost, the product price is reasonable. The 9CrSi shear blade is also suitable for cutting some harder thin plates, such as stainless steel plates. 6Crw2si, Cr12MoV shear blades are suitable for shearing hot-rolled plates, stainless steel, and medium-thick plates. 4Cr5MoSiV1(H13K), 7Cr7Mo2V2Si9(LD), W6Mo5Cr4V2(6542) and other shear blades are suitable for high-speed and high-temperature thermal shearing. The material features are high temperature resistance, not easy to anneal, and a necessary blade for thermal shearing. Shearing machine blade is an important part of shearing machine used to cut various metal materials. Its material and processing determine the use effect of the blade, determine the service life and cutting effect of the shearing machine blade, and the material selection of the shearing machine blade. , Processing and heat treatment determine the hardness and sharpness of the blade, so high-quality machine tools equipped with high-quality blades can greatly improve production efficiency, reduce labor, and improve the quality of shearing.
The blades have been strictly selected materials, carefully processed, high-standard heat treatment, meticulous iron grinding, and strict inspections to ensure the quality of each blade. The materials of the blade are: T8, T10, 9CrSi, 6CrW2Si, Cr12MoV, SKD-11, W6Mo5Cr4v2, H11, H13, etc. The blades have been strictly selected materials, carefully processed, high-standard heat treatment, meticulous iron grinding, and strict inspections to ensure the quality of each blade. Products are widely used in: light industry, aviation, shipbuilding, metallurgy, instrumentation, electrical appliances, stainless steel products, steel structure construction and decoration industries.
