Ironworker shear blades are the core wear-resistant components of ironworker machines (combined punching and shearing machines), specially designed for cold shearing of various metal profiles including angle steel, flat steel, round steel, channel steel and square steel. Applied in steel structure factories, construction sites, metal processing plants and steel works, these blades bear high shear impact, edge extrusion and repeated friction during working, so their material selection, heat treatment and precision processing directly determine the cutting efficiency, workpiece quality and service life of the equipment.
The optimal material of ironworker shear blades is selected based on cutting profile specifications, working frequency and working conditions, with the core principle of balancing high hardness, wear resistance and toughness to prevent chipping and deformation. The three mainstream high-quality materials for industrial-grade ironworker shear blades are as follows:
Key Advantages: Low processing difficulty, easy on-site regrinding, high cost performance, moderate toughness and wear resistance
Applicable Scenarios: Light-load intermittent cutting, small-spec profiles , temporary cutting at construction sites
Suitable for: Small and medium-sized ironworker machines with low working frequency
Core Hardness: HRC 58-62 after vacuum quenching + low-temperature tempering
Key Advantages: Special for cold shearing, excellent hardenability, perfect balance of wear resistance and impact resistance, not easy to chip or deform, 2-3 times longer service life than 9CrSi
Applicable Scenarios: Medium and heavy load high-frequency continuous cutting, conventional industrial profiles , mass production in steel structure factories and metal processing plants
Suitable for: 90% of medium and heavy ironworker machines on the market
Core Hardness: HRC 52-56 after quenching
Key Advantages: Extreme substrate toughness, super anti-chipping and anti-fracture performance, strong adaptability to harsh working conditions with impurities on profile surface
Applicable Scenarios: Extra heavy load cutting, large-spec profiles (≥100mm angle steel, channel steel), high-strength alloy steel cutting, irregular shearing with weld scars/hard slag on workpiece surface
Suitable for: Super heavy-duty customized ironworker machines
Precision Hardness Control: The edge hardness is stable in the standard range, no over-hardening (easy to chip) or under-hardening (fast wear)
Excellent Toughness: Bear instantaneous shear impact without chipping, cracking or deformation
High Wear Resistance: Maintain sharp edge during high-frequency cutting, reduce regrinding and replacement frequency
Our ironworker shear blades are customized for different metal profile cutting, and the blade specifications are precisely matched with the ironworker machine model and the profile size to ensure cutting efficiency and workpiece quality:
Angle Steel Cutting: Adapt to equal angle steel/unequal angle steel of 30mm-200mm side length, the most common application scenario of ironworker machines
Flat Steel Cutting: Adapt to flat steel of ≤50mm thickness, smooth cutting edge, no burr
Round Steel Cutting: Adapt to round steel/steel bar of ≤25mm diameter, precise cutting without deformation
Channel Steel/Square Steel Cutting: Customized special blade design for non-standard profile cutting, adapt to heavy-duty industrial cutting demand
Scientific use and daily maintenance can effectively prolong the service life of shear blades and reduce the comprehensive production cost. The key operation points are as follows:
No Over-spec Cutting: Strictly match the blade specification with the cutting profile size, avoid small blades cutting large-spec profiles to prevent chipping and equipment damagePrecise Gap Adjustment: The shear gap between upper and lower blades = 0.05-0.1×profile thickness, too large gap causes burr, too small gap increases equipment load and blade wear
Clean Workpiece Impurities: Remove weld scars, hard slag and rust on the profile surface before cutting to avoid edge damage by hard foreign objects
Regular Equipment Lubrication: Add butter to the guide rail and pin shaft of the ironworker machine regularly to ensure smooth operation and avoid uneven force on the blade
Professional Material Customization: Select 9CrSi/Cr12MoV/H13 high-quality steel according to your working conditions, 100% raw material quality assurance with material certificate
Advanced Heat Treatment Technology: Adopt vacuum quenching, stable hardness, uniform tissue, perfect balance of hardness and toughness
High-precision Processing: CNC precision processing, strict size tolerance control, smooth edge, no burr, ensure cutting precision
Long Service Life: Industrial-grade wear resistance, the service life is far higher than ordinary carbon steel blades, reduce replacement and maintenance frequency
Customized Service: Provide non-standard blade customization for special ironworker machine models and cutting scenarios, support OEM/ODM
Complete After-sales Service: Provide on-site use guidance and regrinding suggestions, solve all your problems in the cutting process
