SHENCHONG 30mm sheet metal shearing machine is a heavy-duty hydraulic guillotine shear designed specifically for cutting metal sheets ≤ 30mm thick. Common models include QC11Y-30×3200 / QC11Y-30×4000 / QC11K30×3200 / QC11K-30×4000. This equipment is widely used in shipbuilding, bridge construction, steel structures, heavy machinery manufacturing, mining machinery, and military manufacturing.

SHENCHONG 30mm hydraulic guillotine shear is a heavy-duty metal sheet shearing machine. It utilizes a hydraulic drive and guillotine shearing mechanism, capable of shearing steel plates up to 30mm thick (under standard Q235 carbon steel) in a single operation. It is particularly suitable for thick plate processing, heavy industrial manufacturing, and large-scale steel structure projects.

- The guillotine mechanism: The upper blade carriage moves in an arc around a fixed fulcrum, minimizing blade clearance during shearing, resulting in high cut straightness and precision.

- Hydraulic Drive: A hydraulic cylinder drives the upper cutter head, providing high pressure, smooth operation, and low noise.

- Applicable Plates: Carbon steel, stainless steel, low-alloy steel, etc. (For stainless steel, the cutting thickness should be reduced by approximately 30%).

1. 30mm Sheet Metal Shearing Machine Structure

Frame and Worktable

- The welded frame structure is annealed to eliminate internal stress, ensuring strong rigidity and long-term deformation resistance.

- The worktable is equipped with a ball bearing support or material support device for convenient feeding of heavy plates.

Upper and Lower Blade Holder

- The upper blade holder adopts a gate-type arc motion design to ensure cutting accuracy.

- The blade material is mainly 9CrSi, 6CrW2Si, or H13. After heat treatment, the hardness can reach HRC55 or above, and it is highly wear-resistant.

Hydraulic System

- Equipped with a high-pressure hydraulic pump (gear pump or plunger pump) and a relief valve protection.

- Hydraulically controlled cutting action ensures smooth operation and low impact.

Back Gauge

- A digital display or CNC back gauge system is used, with an accuracy of generally ±0.1 to ±0.2mm.

- The stroke range reaches 600 to 1000mm, suitable for cutting large plates.

Blade Gap Adjustment

- Manual or electric adjustment is set according to plate thickness and material to ensure cut quality.

Electronic Control System

- Utilizes PLC control, with push-button station or touch screen operation.

- Features single, continuous, and inching shearing modes.

3. Key Features

- Superior frame rigidity: The machine body is welded from high-strength steel plates and fully annealed, capable of withstanding extreme shearing forces without deformation.

- Hydraulic guillotine drive: Dual cylinders drive the upper blade carrier vertically, ensuring highly straight cuts.

- High-power main motor: Typically ≥ 37kW to ensure sufficient shearing force.

- Highly wear-resistant blades: Cr12MoV, 6CrW2Si, or H13 hot-work die steel are selected for their impact and wear resistance.

- Adjustable blade clearance: Precisely adjust the blade clearance based on different thicknesses and materials to minimize burrs and plate deformation.

- Hydraulic pressing system: multiple points of pressing to prevent thick plates from moving during shearing.

- Safety features: Photoelectric protection, mechanical limit stops, and a protective cover ensure safe operation.

4. Shearing capacity of different materials

When shearing thick plates and high-strength steel, the blades must be sharp and the gaps accurate, otherwise the tool and hydraulic system may be damaged.

- Mass production: Cut to length at steel processing and distribution centers to improve production efficiency.

6. Selection and Purchasing Recommendations

- Sheet Type: If you frequently cut stainless steel, you'll need to increase the power and blade material.

- Cutting Width: Select according to the maximum sheet width (common options are 2500, 3200, and 4000 mm).

- Automation: Optional front and rear feed systems and automatic stacking devices improve efficiency.

- Brand and After-Sales Service: For heavy-duty equipment, we recommend choosing an experienced manufacturer to ensure a long-term supply of parts.

30 mm sheet metal shearing machines are heavy-duty shearing equipment for extra-thick plate. They typically feature a hydraulic guillotine shear structure, equipped with a high-power hydraulic system and a high-strength blade carriage, specifically designed to meet the demands of cutting high-strength, thick steel plates.

SHENCHONG 30 mm metal plate shears are industrial shearing equipment capable of shearing plates up to 30 mm thick (based on Q235 carbon steel). They are typically hydraulically driven, and the blade carriage utilizes a guillotine structure (up and down linear motion), resulting in high shearing precision and strong rigidity.
