Product Overview

Our cnc shearing line is a fully automatic CNC-controlled cut-to-length production line independently developed and manufactured by Taian Lishen Machinery Technology Co., Ltd. Founded in 1996, our factory has rich experience in metal sheet processing equipment and steel drum production machinery. This automatic shearing line integrates uncoiling, leveling, precise sizing and hydraulic shearing into one complete production workflow.

This metal coil shearing line is specially engineered for cutting metal coils into flat, burr-free rectangular sheets with consistent flatness and ultra-high dimensional accuracy. It can process carbon steel, stainless steel, galvanized steel and aluminum sheets, widely used for steel drum manufacturing, solar water heater tank production, sheet metal stamping and general metal fabrication industries. All our CNC shearing machines are certified with ISO 9001 quality system and pass strict 24-hour continuous running tests before shipment, helping factories achieve unmanned and high-efficiency sheet cutting.

Working Principle

The whole cnc shearing line adopts Siemens PLC centralized control system, supporting automatic continuous circulation without frequent manual intervention. The complete working process is simple and systematic:

Step 1 Uncoiling: The hydraulic decoiler steadily loads raw metal coils and feeds raw materials to the leveling unit to avoid material deviation and coil jamming.

Step 2 Leveling: Multi-row solid leveling rollers eliminate internal stress and surface radian of coiled materials, ensuring finished sheets maintain excellent flatness for subsequent welding and stamping processes.

Step 3 CNC Precision Positioning: Workers input target cutting length and quantity on the touch screen. The servo feeding system accurately controls feeding distance to realize fixed-length cutting.

Step 4 Hydraulic Shearing: The high-hardness integral shear blade finishes fast vertical shearing. The hydraulic buffer design effectively reduces burrs and sheet deformation during cutting.

Step 5 Automatic Stacking: Qualified flat sheets are automatically sorted and stacked by the stacking platform, easy for workers to transport and store.

Main Technical Parameters

Core Product Advantages

Ultra-high Cutting Accuracy: Equipped with high-response servo feeding system and original Siemens CNC controller. This automatic cut to length line keeps length error within ±0.5mm, perfectly meeting strict tolerance requirements for steel drum blanks and water heater tank sheets.

Powerful Material Compatibility: Our CNC shearing line can handle various common metal plates. It serves as essential pre-processing equipment for 18L-250L steel drum production lines, solar water heater tanks and pressure vessel manufacturing.

Save Labor & Improve Efficiency: Compared with traditional single shear machines, this integrated production line realizes one-person operation. The maximum running speed reaches 50m/min, greatly reducing manual feeding and measuring work and lowering long-term production costs.

User-friendly Operation & Low Maintenance: The intelligent touch screen can store more than 100 groups of customized cutting parameters for quick switching of different specifications. The centralized lubrication system and heat-treated shear blades extend service life and reduce daily maintenance difficulty.

Safe & Durable Structure: Adopts heavy-duty integral welded steel frame to avoid long-term working deformation. Equipped with emergency stop button and safety protection grating to eliminate potential safety hazards during continuous operation.

Application Industries

This CNC shearing line is widely recognized by global clients and mainly applied in multiple industrial fields: metal packaging industry for steel drum and tin can sheet blank cutting; new energy industry for solar water heater shell and pressure tank sheet processing; sheet metal processing factories for cabinet, enclosure and hardware accessories cutting; automobile parts and general metal stamping industries. It can be perfectly matched with bending machines, rolling machines and CNC welding equipment to form a complete metal processing workshop.
