As the core cutting component of the shearing machine, the material selection, structural design, and technological innovation of metal cutting tools directly determine the cutting accuracy and equipment efficiency. The following are the key technical points:
1、 Classification of Tool Materials and Adaptation Scenarios
Carbon tool steel (T10/65/75 steel): hardness HRC57-59, low cost, suitable for ordinary A3 sheet, low-carbon cold-rolled sheet, and waste recycling scenarios.
Low alloy tool steel (6CrW2Si/Cr12MoV): hardness HRC58-62, strong wear resistance, designed specifically for stainless steel, hot-rolled plates, and medium thick plates.
Alloy tool steel (H13K/LD): high temperature resistance of 800-1000 ℃, strong resistance to quenching, used for hot rolling steel billets and thick steel plate shearing.
2、 Structural design and functional characteristics
Flat blade cutting tool: The cutting edge is flat (with minimal deformation), suitable for high-precision scenarios such as automotive coverings, but with high energy consumption.
Slant blade cutting tool (inclination angle of 1 ° -6 °): reduces shear force by more than 30%, significantly reduces motor power consumption, and is widely used in ordinary sheet metal processing.
Segmented combination cutting tool: customizable length (400-1300mm), flexible maintenance and replacement, suitable for different specifications of shearing machines.
3、 Core application areas
Precision manufacturing: The longitudinal cutting machine tool (made of Cr12WmoV material) achieves cutting from 0.1mm ultra-thin plate to 10mm thick steel plate, with a flatness of ± 0.15mm.
High temperature operation: The cutting tool of the hot shear machine is used to process red hot steel billets above 800 ℃, and the red hardness ensures continuous production stability.
Multi industry adaptation: covering differentiated needs such as ship steel plates, stainless steel products, and building curtain walls.
4、 Performance Enhancement Technology
Laser shock strengthening: After treatment, the cutting edge life of 6CrW2Si steel cutting tools has been increased from 1500 times to 4000 times, and the fatigue strength has increased by 300%.
Intelligent control system: The servo driven flying shear system is paired with a 0.01mm level grating ruler, and the cutting error of a 4000mm long plate is ≤± 0.15mm.
5、 Typical application cases:
Car battery tray: 12mm high-strength steel (tensile strength 980MPa) precision cut.
Stainless steel sink: The inclined blade cutting tool efficiently cuts 304 stainless steel plate, with no burrs on the cut.
