Description

The fish plate, also known as a splice bar or joint bar, is an essential accessory used in railway systems to connect and join two rail ends together. It provides structural integrity, stability, and continuity to the track system, ensuring safe and efficient train operations.

Specifications

Fish plates come in various specifications to match different rail types, track configurations, and operational requirements. Specifications may include parameters such as rail type compatibility, hole placement, dimensions (length, width, thickness), and bolt patterns. These specifications ensure compatibility between the fish plate and the specific rail profile for a secure and reliable connection.

Common Standard Sizes

Standard sizes for fish plates can vary depending on the specific railway system and regional regulations. Common standard sizes include lengths ranging from approximately 12 inches (30 cm) to 24 inches (61 cm), widths averaging between 4 inches (10 cm) and 6 inches (15 cm), and thicknesses varying between 0.5 inches (1.3 cm) and 1 inch (2.5 cm). However, it's important to note that these sizes can differ based on the specific rail type and regional standards.

Materials and Manufacturing Process

Fish plates are typically made from high-strength materials capable of withstanding heavy loads and providing long-lasting durability. Commonly used materials include steel or ductile iron. The manufacturing process involves precision machining, forging, or casting techniques to create the desired fish plate structure and dimensions. Surface treatments, such as galvanization or painting, may be applied to enhance corrosion resistance and longevity.

Installation and Usage

Fish plates are installed at rail joints to connect two rail ends securely. They are placed over the jointed rail ends and fastened using bolts and nuts. Proper installation, routine inspection, and maintenance are crucial for safe and reliable train operations. Compliance with industry safety standards and regular checks for bolt tightness and any signs of wear or damage are necessary to ensure the integrity and strength of the fish plates.

Processing advantage

1. The spiral blade produced by the continuous cold rolling method overcomes the shortcomings of the traditional spiral blade production process, such as poor precision, difficult forming and high consumption of materials, and low production efficiency.

2. After the blade is formed, the surface is smooth and the dimensional accuracy and surface hardness are high.

3. Provide continuous integral blades according to the helical length required by customers, with good rigidity, convenient and fast welding and assembly during use.
