Edge curling is a special metalworking operation, to make the edges of a round or a flat sheet metal into hollow rings and this operation is carried out when there is a need of fixing one part on the other with air or watertight closure for safe handling. The rims of the round metal part are first cut (or also called trimmed) and then can be bent outside or inside by a special metal tool called “sheet metal curling tool”. In this way, the part has a better finishing and the rims have no longer the risk of cutting by usage.
The curling usually takes a few seconds more time in comparison to edge cutting operation. The operator needs to remove the edge cutting tool and put on the edge curling tool to go on with the curling.
Edge curling operation can be applied on metals such as:
- Stainless steel
- Black steel
- Aluminum
- Copper
- Tin
- Zinc
The edge curling (or edge closing) is also widely applied in bakeware production facilities. The stainless steel cake, aluminum or alusteel cake molds (or more generally bake molds) are also manufactured by a drawing hydraulic press and the rims of these molds are trimmed first by an edge trimming machine and then curled inside or outside depending on the application.
The curling of sheet metals can be applied to the parts as below
- Cake molds
- Teapots and coffee pots
- Milk canisters
- Water heater bodies
- Kettles
- Bakery products
What is curling in sheet metal?
Curling in sheet metal is a metalforming process that creates a rolled or curled edge on sheet metal components. It is a versatile and widely used technique that serves various purposes, including:
- Reinforcing edges: Curling strengthens the edges of sheet metal components, making them more resistant to damage and wear. This is particularly important for components subjected to frequent handling or potential impacts.
- Eliminating sharp edges: Curling eliminates sharp edges that can pose safety hazards or cause discomfort during handling. The rounded edge created by curling provides a smoother, safer finish.
- Enhancing aesthetics: Curling can enhance the aesthetic appearance of sheet metal components by creating a clean, uniform edge. This is often desirable for components that are visible or have decorative elements.
- Preparing for welding: Curling can prepare the edges of sheet metal components for welding by aligning them and providing a consistent surface for the weld bead. This can improve the quality and strength of the welded joint.
- Guiding fluid flow: In applications where sheet metal components are used to guide fluid flow, curling can help create a smooth, consistent internal profile that minimizes turbulence and enhances fluid flow characteristics.
Methods of Curling Sheet Metal
There are several methods for curling sheet metal, each with its own advantages and limitations. Some of the most common methods include:
- Manual Curling: Manual curling involves using hand tools, such as curling pliers or a hammer and dolly, to bend the edge of the sheet metal. While this method is simple and inexpensive, it can be time-consuming and may not provide the precision and consistency required for critical applications.
- Roll Forming: Roll forming utilizes a series of rollers to gradually bend the edge of the sheet metal into the desired curl radius. This method offers high precision and consistency, but it requires specialized equipment and may not be suitable for small-scale or complex shapes.
- Press Forming: Press forming utilizes a press brake or other stamping equipment to press the edge of the sheet metal into a die that forms the desired curl shape. This method is suitable for high-volume production and can produce complex curl profiles.
- Edge Cutting Trimming and Forming Machines: Edge cutting trimming and forming machines are versatile machines that can perform a variety of edge finishing operations, including curling. These machines offer a combination of precision, efficiency, and versatility, making them a popular choice for various sheet metal applications.
Factors Affecting Curling Process
The curling process is influenced by several factors, including:
- Sheet Metal Thickness: Thinner sheet metal is generally easier to curl than thicker sheet metal, as it requires less force and is more pliable.
- Sheet Metal Material: The material of the sheet metal also affects the curling process. Softer materials, such as aluminum, are generally easier to curl than harder materials, such as steel.
- Curl Radius: The desired curl radius affects the curling process. Smaller curl radii require more precise tooling and control, while larger curl radii are more forgiving.
- Lubrication: Lubrication can be applied to the sheet metal to reduce friction and prevent galling during the curling process.
- Tooling: The type and quality of the curling tool significantly impact the curling process. Proper tool selection and maintenance are essential for achieving consistent results.
- Machine Settings: Machine settings, such as speed, pressure, and feed rate, must be adjusted appropriately for the specific sheet metal thickness, material, and curl radius.
Curling is a valuable technique in sheet metal fabrication, offering a range of benefits and applications. By understanding the curling process, factors affecting it, and the appropriate methods and equipment, manufacturers can effectively curl sheet metal components to achieve the desired strength, aesthetics, functionality, and consistency.
Curling is one of the sheet metal forming applications to make the flat or round rims (edges) of a part hollow and circular roll. After the curling, the outer geometry of the edge changes completely. The thickness of the edge becomes the diameter of the hollow roll.
The curling operations can be made on the center of the roll or off the center of the roll. These two applications need separate machine tool designs
The curling tool moves vertically on the sheet metal edge of the part while the part rotates about its own axis. The curling tool has a special hemisphere geometry and needs to be manufactured with a harder material than the part itself to withstand the wear and friction. The curling tool moves up and the contact of the part edge must be on the edge of the curling tool inside, maximum closest to the hemisphere finishing corner. the diameter of this hemisphere determines the outer diameter of the curling roll of the sheet metal part.
The speed of the upward movement of the curling tool (or curling die) is critical. This speed is calculated according to the yield strength of the material of the part. The bigger the yield strength, the slower the curling die needs to move upward in order no to damage the part edge
In our edge cutting trimming beading or curling machines, the movement and the speed of the curling die is controlled by a servo motor (which is also controlled by a PLC) to make the process go smoother.
