Servo-Driven Automatic Shearing Machine for Blanks
Servo-Driven Automatic Shearing Machine for Blanks
The Automatic Shearing Machine is the precision cutting station in your steel drum production line. Following the leveling process, it takes over to produce the final, accurately sized blank. Its sole function is to make rapid, clean, and perfectly repeatable cuts. The length precision of each blank directly determines the circumference and quality of the final drum body, making this machine indispensable for maintaining dimensional consistency and high throughput. It is the essential step for preparing blanks for 200L/210L steel drums from cold rolled or galvanized steel.
The machine can be supplied individually for an existing cutting line or integrated with:
· Hydraulic coil decoiler
· Steel coil precision straightener
- Servo feed automatic shearing machine
· Automatic coil stacking and squaring system
The shear operates on a servo-driven feed and precision mechanical cutting principle for unmatched accuracy.
Core Structure: The machine consists of a rigid C-frame made from thick steel plate, a fixed lower blade, a moving upper blade, a precision gear drive system, a servo-driven feeder, and a PLC control cabinet with touchscreen HMI.
Control Logic: The cutting length is programmed into the PLC. The servo feeder advances the material to the exact set length, then signals the shear to execute the cut. The entire cycle is automated and synchronized with the line speed.
Process Flow:
The leveled sheet is fed into the shear by the servo-driven feeder.
When the sheet has advanced to the exact pre-programmed length, the feed stops with servo precision.
A clutch engages, and the powerful upper blade, driven by the gear system, descends to make a clean, instantaneous cut against the hardened lower blade.
The cut blank is discharged onto a conveyor or stacking system, and the cycle repeats.

Drum Types: For producing blanks for standard 200L, 210L, and other cylindrical steel drums.
Material Specification: Cold rolled steel, galvanized steel, aluminized steel strip.
Industries: A key component in steel drum manufacturing lines for the chemical, food, paint, and petroleum industries.
Cutting Length Range: The servo system can be programmed for a wide range of blank lengths to suit different drum diameters.
Speed & Throughput: Configured for low (1-2/min), medium (5-6/min), or high-speed (7-8/min) production lines.
Control Integration: PLC brand (Siemens, Mitsubishi, Omron) can be specified to match your plant's control architecture. Custom I/O interfaces for seamless line integration.
Blade Specification: Blades can be tailored for different materials or for specialized edge profiles if required.
Clean, Burr-Free Edges: Sharp, hardened blades and an immensely rigid frame produce clean cuts, minimizing the need for secondary deburring and providing ideal edges for welding.
High Repeatability & Consistency: Servo-driven feed length combined with PLC control ensures each blank is identical, which is vital for automated downstream processes like rolling and welding.
Reduced Operating Cost: The four-edge blade design quadruples service life between changes, significantly lowering consumable costs and reducing downtime for blade maintenance.
Simple & Robust Integration: Designed to work seamlessly with the preceding leveling machine and subsequent conveyor or stacking system, ensuring a continuous, trouble-free material flow.
PLC Brand Selection: Choice of Siemens, Mitsubishi, Omron, or other major brands.
Safety Package: Integration of safety light curtains, two-hand operation buttons, or emergency stop systems to meet local regulations.
Voltage & Frequency: Machine can be built for 380V/50Hz, 440V/60Hz, or other specific regional standards.
Discharge Options: Customized belt conveyors, stacking tables, or turnover devices for efficient blank handling.
Q: How do I determine the right shear for my needs?
A: Model selection should be based on material width, minimum and maximum thickness, steel yield strength, required blank length, cutting-length tolerance and production speed.
Please also provide information about the upstream straightener and downstream stacking system so that feeding height, line direction and control signals can be confirmed.
Q: What is the lead time and installation process?
A: Standard models have a lead time of 8-10 weeks. We provide detailed layout drawings and can offer on-site installation and commissioning services to ensure optimal integration with your line.
Q: Are your shears CE certified?
A: Yes, our machines are designed and constructed to comply with CE safety directives. Other certifications can be evaluated upon request.
Q: What is the typical blade life and are spare parts available?
A: Blade life depends on material and thickness, but the 4-edge Mo-V design offers extended life. We keep critical spare parts, including blades, in stock for rapid delivery to minimize your downtime.
