Hydraullic Shearing Machine / Sheet Bending

Working Principle

Uses a moving upper blade and fixed lower blade with a set blade gap to apply linear shearing force—similar to scissors—to cut sheets of various thicknesses.

Comparison with Laser Cutting

Shearing machines cut only straight lines, not curves.

They offer higher efficiency with average speeds of 10–15 cuts per minute.

No programming is required, making operation simpler and faster for straight-cut production.

  Key features include :

MD11-1 CNC System: Simple, economical controller offering precision control; directly drives motors and supports easy accessory replacement.

Blades: Upper and lower blades with two cutting edges; made from high-quality materials for wear resistance and long life.

Guardrail: Encloses the blade area for safety.

Blade Adjustment Screw: Allows easy blade alignment and removal.

Backgauge: Controlled by MD11-1; supports and positions the sheet for stable, accurate cutting.

Pressing Cylinder: Hydraulic press mechanism that holds the sheet firmly using multiple oil cylinders and tension springs.

Hydraulic Cylinder: Main power source; the motor drives the hydraulic cylinder to generate cutting force through oil pressure.

Workbench: Supports the sheet with an auxiliary knife seat for fine blade adjustment.

Roller Table: Includes feeding rollers for smooth operation.

Electrical Box: Located on the left; all controls are placed on the front panel, with symbols indicating each function. Includes a manual oil pump for lubrication.

Foot Switch: Controls start/stop and cutting operations, improving safety and convenience.

Return Nitrogen Cylinder: Provides nitrogen to return the knife holder; nitrogen is pre-filled and recyclable.

Solenoid Pressure Valve: Regulates hydraulic oil flow and pressure to protect the system and save energy.

Application Industries

Shearing and bending machines are widely used across industries—from small non-ferrous and ferrous sheet processing, appliances, décor, kitchenware, cabinets, and elevator doors, to large-scale sectors like automotive, shipbuilding, and aerospace. CNC shearing and bending machines continue to gain importance due to their precision and efficiency.

Aerospace

Requires extremely high precision; high-accuracy CNC shearing machines are used for efficient, accurate cutting.

Automobile & Shipbuilding

Large CNC hydraulic shearing machines handle major plate-cutting tasks before secondary processes such as welding and bending.

Electrical & Power

Used to cut plates into various sizes before bending to create computer cases, electrical cabinets, refrigerator or AC housings, etc.

Decoration Industry

High-speed shearing machines, often paired with bending equipment, are used for metal cutting, doors and windows, and specialized décor work.
