Steel bar bending machines are crucial in the construction industry, providing precise bending capabilities for steel bars of various diameters. Here’s an overview of the different types of steel bar bending machines, including their structures, working principles, and unique features:
Worm Gear Type Steel Bar Bending Machine
Structure:
- Components: Frame, electric motor, transmission system, working mechanism (working plate, insertion seat, holder, rotating shaft), and control system.
Working Principle:
- Operation: Motor power is reduced through spur and worm gears to rotate the working plate. Steel bars are fixed between the central axis and the forming axis, allowing the forming shaft to rotate and bend the steel bar.
Features:
- Flexibility: Can bend steel bars into various shapes.
- Adaptability: Central and forming axis holes accommodate different steel bar diameters.
Gear Type Steel Bar Bending Machine
Structure:
- Components: Electric motor, gear reducer, working mechanism, and electrical control system. Includes an automatic angle control mechanism and braking device.
Working Principle:
- Operation: Powered by a braked motor, with adjustable insert seats for bending different specifications of steel bars. Angle control is achieved using pre-selection mechanisms and limit pins.
Features:
- Precision: Provides precise angle control.
- Safety: Equipped with automatic braking and safety features such as emergency stop and motor protection.
Steel Bar Hoop Bending Machine
Structure:
- Components: Similar to other bending machines but designed specifically for stirrups. Includes an eccentric disk, connecting rods, racks, and a working plate.
Working Principle:
- Operation: Motor power drives the eccentric disk, which moves the connecting rods and racks to rotate the working plate and bend steel bars into stirrups.
Features:
- Adjustability: Adjustable bending angle.
- Production: Ideal for mass production of stirrups with consistent shapes.
Hydraulic Steel Bar Cutting and Bending Machine
Structure:
- Components: Hydraulic transmission system, cutting mechanism, rigid mechanism, engine, and body.
Working Principle:
- Operation: Electric motor drives hydraulic pumps for both cutting and bending operations. Hydraulic pressure drives the cutting piston and rotary hydraulic cylinder for bending.
Features:
- Automation: High automation with dual-purpose functionality for cutting and bending.
- Precision: Precise cutting with hydraulic pressure control.
Conclusion
Each type of steel bar bending machine has unique features tailored to specific bending and shaping needs in construction projects. Understanding their structures and working principles helps operators select the most suitable machine for efficient and precise steel bar processing, ultimately enhancing productivity and quality in construction operations.
