sheet metal shearing machines Introduction to Blades

The blade material of the shearing machine is generally T10, 9CrSI, 6CrW2Si, Cr12MoV, H13, alloy steel, and other materials. Products are widely used in the light industry, aviation, shipbuilding, metallurgy, instrumentation, electrical appliances, stainless steel products, steel structure construction, and decoration industries sheet metal shearing machines.

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 sheets of various thicknesses to make the sheets break and separate according to the required size. The shearing machine is a kind of forging machinery, and its main function is in the metal processing industry. General shears can be divided into pedal type (manpower), mechanical type, hydraulic swing type, hydraulic brake type sheet metal shearing machines.

Shearing machines are often used to cut blanks with straight edges. The shearing process should be able to ensure the straightness and parallelism requirements of the sheared surface of the sheared sheet, and minimize the distortion of the sheet to obtain high-quality workpieces sheet metal shearing machines.

Blade material

The materials selected for the shearing blades are divided into three categories: carbon-bonded tool steel, low alloy tool steel, alloy tool steel, etc.

1. Carbon-bonded tool steel: Carbon-bonded steel generally chooses 65, 75 steel, T8, T10 and other materials. The heat treatment hardness of the blades produced by this material is within the range of HRC57-59 degrees, which is suitable for ordinary low-carbon cold-rolled plates and ordinary A3 plates. Compared with the recycling and cutting of waste materials, this feature is low cost and reasonable product price.

2. Low-alloy tools: The commonly used materials for the blades of low-alloy tool steel are: 6Crw2sI, Cr5Mo1V, 9CrSi, Cr12MoV, etc. The heat treatment hardness of the blade is within the range of HRC58-62 degrees. Shearing of medium and thick plates sheet metal shearing machines.

3. Alloy tool steel: The shearing 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-cutting medium and thick steel plates, etc. This feature is high-temperature resistance, not easy to anneal, and is used for hot rolling and hot shearing processes in steel mills.
