Basic Components of Custom Roll Forming
Roll Forming Machine
This is the primary piece of equipment used in the custom roll forming process. It consists of a series of roll forming stations, each containing a set of rollers or ‘rolls,’ which progressively shape the metal material into the desired profile. Typically, a roll forming machine is accompanied by auxiliary equipment such as a decoiler or uncoiler to handle the raw material, a straightener to ensure the metal strip remains flat, and a cut-off or punching system to produce the finished roll-formed components.
Roll (or Roller)
A cylindrical tool, typically made of hardened steel or carbide, that is mounted onto the roll forming machine’s spindle. The roll has a precisely shaped groove or profile, which sequentially deforms the metal material passing through the roll forming stations. Multiple rolls, in pairs or sets, work together within each station to achieve the desired cross-sectional shape of the roll-formed component.
Die
A die is a tool used in various manufacturing processes, including roll-forming, extrusion, and stamping. In custom roll forming, the term ‘die’ is often used interchangeably with ‘roll.’ The die or roll bears a specific shape or profile, which is transferred to the metal material as it passes through the roll forming stations.
Key Roll Forming Processes and Techniques
Progressive Dies
In the roll-forming process, progressive dies are a series of integrated die stations arranged in a linear fashion along the roll forming machine. As the metal strip feeds through the machine, each die station progressively contributes to the part’s shaping, resulting in the final profile. Progressive dies are advantageous for high-speed production and can often incorporate additional features such as hole punching or cutting during the roll-forming process.
Line Dies
Line dies, or single station dies, are dies that perform only one operation or form per station in the roll-forming machine. Each die set is assembled in a linear progression, with each station completing a specific shaping operation on the metal material. Line dies are best suited for applications that require complex bend sequences or the production of large, intricate components.
Pre-Punching and Inline Punching
Pre-punching refers to the process of performing various hole punching, notching, or cutting operations on the metal material before it enters the roll-forming machine. This technique is sometimes preferred when the part’s features are too complex to execute inline during the roll-forming process.
In contrast, inline punching involves performing punching, cutting, and other operations on the metal strip as it moves through the roll-forming machine. This method can increase production efficiency, as multiple processes are completed simultaneously, reducing material handling and production times.
Materials Used in Custom Roll Forming
Carbon Steel
This is a popular material used across various industries, thanks to its balance of strength, ductility, and cost-effectiveness. Carbon steel contains a mixture of iron and carbon, which properties can be altered by adjusting the carbon content. In custom roll forming, carbon steel is commonly chosen for its versatility, wide range of possible shapes, and excellent formability.
Stainless Steel
Stainless steel is a corrosion-resistant variant of steel, due to the presence of chromium in its composition. Custom roll forming can accommodate various grades of stainless steel, offering excellent strength-to-weight ratios, high corrosion resistance, and a sleek aesthetic appeal. Stainless steel is a popular choice for applications requiring durability, extended service life, and aesthetic considerations.
Aluminum
Aluminum is a lightweight yet strong metal that is often used in custom roll forming. It offers high corrosion resistance, excellent formability, and a range of surface finishes. Aluminum is often considered for applications where weight reduction, structural strength, and durability are paramount, such as in the transportation or aerospace industries.
Design Considerations in Custom Roll Forming
Profile Design
The profile design is the cross-sectional shape of the roll-formed component, which is determined by the precise shape of the rolls or dies in the roll-forming machine. Profile design is an essential aspect of the custom roll-forming process, as it dictates the component’s functionality, structural integrity, and connection abilities. Detailed profile design ensures a roll-formed part meets the desired requirements and performance specifications.
Material Thickness
In custom roll forming, the thickness of the metal material plays a vital role in determining the feasibility of a specific profile design and the overall structural strength of the finished component. Different material thicknesses may require unique roll designs, forming processes, additional dies, and tooling strengths. Understanding the correlation between material thickness and profile design is key to producing high-quality roll-formed components.
Tolerances
Tolerances in the custom roll-forming process refer to the allowable variation in the dimensional accuracy of the finished component. These tolerances are essential to ensuring precise fit and function of the roll-formed part in its intended application. Factors that can impact tolerances in custom roll forming include material properties, forming process accuracy, and die/tooling design. Roller Die is proud that we consistently hold tighter than industry standard tolerances and can, with additional tooling, hold even tighter tolerances.
Challenges and Solutions in Custom Roll Forming
Springback
Springback is a phenomenon that occurs when the metal material returns partially to its original shape after being deformed in the roll-forming process. It can affect the dimensional accuracy and overall quality of the roll-formed component. Springback can be mitigated through various methods, including adjusting the tooling design to compensate for potential material recovery, monitoring the roll-forming machine’s settings, and controlling the material properties, such as its thickness and yield strength.
Material Surface Defects
Maintaining the pristine condition of the metal surface during the roll-forming process is crucial for achieving a high-quality final product. Surface defects can result from material handling practices, contamination, or improper machine settings. Effective solutions to minimize surface defects include thorough material inspection, ensuring proper material handling, maintaining a clean production environment, and employing protective films or lubricants during roll forming. Material surface defects can also occur if the product is not shipped promptly to the customer, so our team works to ensure that we’re rolling enough product for just-in-time delivery and are not leaving parts outside longer than necessary.
Joining Methods and Techniques
Selecting the appropriate joining method is essential in custom roll forming to ensure the functionality and durability of the final component. Common joining techniques include:
– Welding: Traditional welding methods, such as MIG (Metal Inert Gas) or TIG (Tungsten Inert Gas) welding, can be utilized to join roll-formed parts. Laser welding is also becoming more popular in custom roll forming for its precision, speed, and minimal heat-affected zone.
– Mechanical Seaming: Involves folding or interlocking edges of roll-formed components to create a mechanical joint. This method is often used in the construction of standing seam roofing panels or HVAC ductwork.
