Stainless steel products, steel structure buildings, electrical equipment, and engineering machinery.
Cutting materials include steel plates, copper plates, aluminum plates, and some non-metallic plates.
The commonly used materials for hydraulic shearing machine blades include T10 carbon tool steel, 9CrSi low-alloy tool steel, 6CrW2Si alloy steel, H13 hot work die steel, LD special steel, Cr12MoV high carbon and high chromium steel, etc.
Performance requirements: Must meet high wear resistance, fatigue resistance, and high temperature stability to cope with long-term high-frequency shear operations.
Processing requirements: It is necessary to ensure the verticality and flatness of the cutting surface, reduce plate distortion, and meet the precision requirements for subsequent welding or assembly.
Different materials correspond to different cutting requirements:
|
9CrSi |
Hardness HRC57-59, suitable for shearing ordinary carbon steel plates (such as A3 plates) |
|
6CrW2Si |
Can cut ordinary plates and stainless steel |
|
H13/LD/Cr12MoV |
High wear resistance, high temperature resistance, suitable for high-strength metals such as stainless steel and alloy steel |
Some blades also use hard alloy inlay or brazing high-speed steel technology to enhance durability.
Hydraulic shearing machine blades are divided into the following two categories:
1.Hydraulic swing blade: It completes cutting through arc-shaped swing and is suitable for medium and small thickness plates.
2.Hydraulic brake blade: moves straight up and down, with higher cutting accuracy, suitable for thick plates and high-precision requirements.
Before operation: Wear protective equipment and confirm that the equipment is in normal condition.
Parameter adjustment: Adjust the blade gap according to the thickness of the board, and calibrate the mold or fixture according to the width.
Material restrictions: Cutting of hard marks, welding slag, or excessive thickness materials is prohibited.
Maintenance requirements: Add lubricating oil every shift and regularly check the condition of bearings and blades.
Conventional dimensions: such as 1025 × 125 × 32, 1300 × 80 × 20, etc. (unit: mm).
Customized length: Supports customization of seamless blades ranging from 2 meters to 6 meters.
Hardness range: HRC48 ° -74 °, adjusted according to material and heat treatment process.
Daily maintenance: Regularly clean debris and avoid corrosive substances from contacting the blade.
Refurbished use: After wear and tear, the cutting edge can be re sharpened to improve utilization.
Through reasonable material selection, standardized operation, and regular maintenance, hydraulic shearing machine blades can significantly improve cutting efficiency and extend service life.

What materials are commonly used for hydraulic shearing machine blades?
Common materials include T10 carbon tool steel, 9CrSi low-alloy tool steel, 6CrW2Si alloy steel, H13 hot work die steel, LD special steel, and Cr12MoV high-carbon high-chromium steel. These materials ensure high wear resistance, fatigue resistance, and temperature stability.
Can guillotine shear blades cut different types of metal plates?
Yes, they are widely used to cut steel plates, stainless steel, aluminum plates, copper plates, and some non-metallic sheets, making them versatile for various metal processing industries.
How do I ensure safety when using guillotine shear blades?
Always wear protective equipment, check that the equipment is functioning normally, adjust the blade gap according to material thickness, and avoid cutting hard marks, welding slag, or excessively thick materials.
How can I maintain hydraulic shearing machine blades for longer lifespan?
Clean debris daily, avoid corrosive substances, regularly lubricate bearings and blades, and re-sharpen the cutting edge when worn. Proper maintenance significantly improves cutting efficiency and service life.
Can guillotine shear blades be customized?
Yes, blades can be customized in length from 2 meters to 6 meters, with conventional dimensions such as 1025 × 125 × 32 mm or 1300 × 80 × 20 mm. Hardness can be adjusted from HRC48° to 74° based on material and heat treatment.
What industries commonly use hydraulic shearing machine blades?
