Definition and function of cast iron right angle bending plate

Cast iron right angle bending plate is a 90 ° right angle positioning device made of cast iron material, which is quickly connected to a three-dimensional welding platform through a T-shaped groove structure. It is mainly used for vertical positioning and support of heavy workpieces. Its core advantages include:

• High rigidity: Cast iron material (such as HT200/HT250) has high compressive strength and is suitable for heavy load conditions;

Wear resistance: After surface quenching treatment, the hardness reaches HRC40-45, and the ability to resist welding slag wear is strong;

Stability: Cast iron has low internal stress and is not easily deformed after long-term use.

Classification and characteristics of cast iron right angle bending plates

1. Standard cast iron right angle bending plate

• Structure: Double sided T-shaped groove design, right angle accuracy ± 0.03mm/m;

• Size: Common specifications include 200mm x 200mm x 15mm (length x height x thickness);

• Load bearing: Single point static load can reach 8-12 tons;

• Typical applications:

Vertical welding of large steel structural components (such as bridge support columns);

Multi sided positioning of construction machinery bases.

2. Reinforced cast iron bending plate

Design: Add triangular reinforcement ribs to the back to enhance bending strength;

• Applicable scenarios:

Workpieces with concentrated loads on one side (such as welding of crane boom);

Complex working conditions that require resistance to torque.

3. Adjustable angle cast iron bending plate

• Structure: Angle adjustment is achieved through a worm gear mechanism (such as 85 ° -95 °);

Locking method: bolt+cone locking, repeated positioning accuracy ± 0.1 °;

• Features:

Balancing the rigidity and angular flexibility of cast iron;

· Suitable for accurate positioning of slant support weldments.

Installation and adaptation of cast iron right angle bending plate

Installation method

1. Connect with the platform:

Fixed to the 3D platform using T-slot bolts, it is recommended to use flat washers and spring washers to prevent loosening;

Multiple curved plates can be combined to form a stepped positioning structure.

2. Connection with workpiece:

Directly fix the workpiece through pressure plates, bolts, or magnetic fixtures;

Thin walled workpieces need to be equipped with cushioning pads (such as rubber sheets) to prevent indentation.

Adaptation suggestions

Platform compatibility: It is necessary to match the size of the T-shaped slot on the platform (such as 14mm, 18mm);

• Workpiece adaptation:

For heavy workpieces with a thickness of ≥ 10mm, cast iron bent plates are preferred;

When frequent angle adjustment is required, an adjustable cast iron bending plate can be selected;

Anti deformation design: It is recommended to use symmetrical load distribution for long-term load-bearing.

Selection and maintenance suggestions

Key parameters for selection

Material: HT200 (normal load) or HT250 (heavy load);

Accuracy level: ordinary level (± 0.05mm) or precision level (± 0.02mm);

Surface treatment: Blackening treatment for rust prevention or hard chrome plating for enhanced wear resistance;

Attachment options: Customizable scale lines, eyelets, etc.

Maintenance points

1. Cleaning and maintenance:

Clean the welding slag in the T-shaped groove in a timely manner after welding;

Use kerosene or specialized cleaning agents to remove oil stains;

2. Anti corrosion: Regularly spray anti rust oil (recommended WD-40);

3. Accuracy testing: Use a ruler to measure angle deviation every six months. If it exceeds the tolerance, it needs to be returned to the factory for calibration.

Extended product recommendations

Cast iron magnetic bending plate: The bottom is embedded with a strong neodymium iron boron magnet, which quickly adsorbs onto the platform;

Cast iron bending plate component: including matching bolts, gaskets, and anti rotation pins, to achieve quick installation;

Cast iron bent plate bracket: with rollers and brakes, it can move and support large workpieces.

Additional explanation:

Comparison between cast iron bending plate and aluminum alloy bending plate:

Cast iron: high rigidity, low cost, suitable for static heavy load;

Aluminum alloy: lightweight, easy to process, suitable for dynamic adjustment.

For high-precision requirements, it is recommended to install and verify with a laser calibration system.
