Before diving into the working mechanism, let’s explore the key components of a typical slip roll forming machine. These include:
- Çerçeve: The sturdy frame provides the foundation and support for the entire machine.
- Rollers: There are three main rollers – two lower and one upper. The sheet passes through the lower rollers, and the upper roller applies pressure to bend the material.
- Adjustment Mechanism: This allows operators to adjust the distance between the rollers to accommodate different sheet thicknesses.
3.2 The Rolling Process
The rolling process with a slip roll forming machine involves the following steps:
- Preparation: The operator sets the machine and adjusts the rollers based on the desired bend radius and material thickness.
- Sheet Insertion: The metal sheet is carefully inserted between the lower rollers.
- Bending: As the sheet is pulled through the rollers, the upper roller exerts pressure on the sheet, bending it to the desired shape.
- Repetition: For multiple bends or longer sheets, the process is repeated until the entire sheet is formed.
3.3 Material Options and Thicknesses
Slip roll forming machines can handle various materials, including mild steel, stainless steel, aluminum, and copper. The thickness of the material that can be bent depends on the machine’s capacity, with some machines capable of handling thicker sheets than others.
