In this comprehensive guide, we will delve into the ins and outs of metal stamping, covering its types, the equipment used, the design processes, and more. Whether you’re a professional in the field, a curious engineering student, or someone who simply wants to understand the underpinnings of everyday products, this guide will provide you with everything you need to know about metal stamping.
The Basics of Metal Stamping
Metal stamping is a manufacturing process that uses dies and stamping presses to transform flat sheet metal into specific shapes. It is a complex process that includes a range of metal forming techniques such as punching, blanking, embossing, bending, flanging, and coining.
The foundation of metal stamping lies in the precise application of pressure on the metal sheet, which is placed in a die that has the negative of the desired shape. A stamping press, which is a specially designed machine tool, applies a high-pressure downward force onto the metal, causing it to form into the specific shape outlined in the die.
Advatages of metal stamping
A key advantage of metal stamping is its versatility. By using customized dies, manufacturers can create a wide array of intricate designs and shapes. This manufacturing technique is capable of producing high volumes of consistent, high-quality metal parts efficiently. Moreover, metal stamping can be used with a variety of metals, including steel, aluminum, copper, brass, bronze, and stainless steel, making it a flexible solution for many industrial applications.
Disadvantages of metal stamping
While metal stamping is a cost-effective production method for large quantities, the initial tooling costs can be relatively high due to the design and creation of specific stamping dies. Nevertheless, when spread over large production volumes, the cost per unit becomes remarkably low.
How does Metal stamping work?
The metal stamping process begins with a flat sheet of metal, commonly referred to as a ‘blank’. This blank is placed into the stamping press, where the die and punch are located. The punch is a component of the stamping press that moves downward and forces the metal into the die, creating the desired shape.
Step 1: Material Preparation
The metal stamping process begins with material preparation. A flat sheet or coil of metal, often referred to as a blank, is selected based on the requirements of the part being produced. The material can vary in thickness, size, and type, depending on the specific application.
Step 2: Tool and Die Design
Once the material is prepared, the next step involves designing the tooling, including the dies and punches. The dies consist of a female die (containing a cavity) and a male punch (matching the cavity shape). The tool and die design is crucial as it determines the final shape and features of the stamped part.
Step 3: Setup and Alignment
In this step, the blank is fed into the stamping press, and the tooling is aligned to ensure precise positioning of the blank. Proper alignment is essential for consistent and accurate stamping throughout the production process.
Step 4: Stamping Operations
With the setup complete, the stamping process begins. The press applies force to the blank, forcing it into the cavity of the die. The metal deforms and takes the shape of the die, forming the desired features and contours of the part. The press stroke can be a single operation or a series of operations, depending on the complexity of the part.
Step 5: Secondary Operations
After the initial stamping operation, additional secondary operations may be performed to refine the part or add specific features. These operations can include bending, coining, embossing, piercing, or trimming.
Types of Metal Stamping
Once we have a firm understanding of the basics of metal stamping, we can delve into the different types of stamping processes. The type of stamping chosen largely depends on the complexity of the part, production volume, and the specific requirements of the project.
Progressive Stamping
In progressive stamping, a continuous metal strip is fed into the stamping press, which moves the strip through a series of stations. Each station in the press performs a specific operation on the metal strip, gradually transforming it into the final part shape. These stations can include operations such as piercing, blanking, bending, drawing, coining, or forming.
The strip is advanced by the press between each operation, allowing for sequential operations to be performed in a continuous manner. As the strip progresses through the press, the part undergoes a gradual transformation, with each station adding a specific feature or forming operation.
It is commonly used to manufacture components such as brackets, clips, connectors, terminals, electrical contacts, and intricate metal parts with precise tolerances.
Deep Draw Stamping
Deep draw stamping is a specialized metal stamping process used to create cylindrical or box-shaped parts with significant depth. It allows for the production of seamless, hollow components that have a higher depth-to-diameter ratio compared to other stamping techniques.
The working process is as below:
Blanking: A flat metal sheet is cut from a larger coil or sheet material to create a blank of the required size and shape.
Placing and Clamping: The blank is placed onto a draw ring, which holds it firmly in place during the deep draw stamping process. The draw ring prevents the blank from wrinkling or buckling during the forming operations.
Drawing: The punch descends and pushes the metal blank into the cavity of the die, causing it to deform and take on the shape of the die. The material is stretched and thinned as it is drawn deeper into the die cavity.
Redrawing: In some cases, the process may involve multiple redraw operations to achieve the desired depth and shape. This is done by transferring the partially formed part to another set of dies for further shaping and redrawing.
Trimming: After the deep draw stamping process, excess material is trimmed off from the formed part to achieve the final shape and dimensions.
This process is commonly used to create parts like cans, tanks, sinks, and anything that requires depth and roundness.
Fourslide Stamping
Fourslide stamping, also known as multislide stamping or four-way stamping, involves a horizontal alignment of four sliding tools.Fourslide stamping utilizes a multislide machine equipped with multiple slides that move horizontally and vertically. Each slide carries various tools, including punches, forming tools, and cutoff tools. As the metal strip is fed into the machine, the slides work in synchronization to perform multiple operations simultaneously.
It’s an ideal process for creating complex components, such as wire forms or springs, with multiple bends or twists.
Fineblanking
Fineblanking is a precision metal forming process used when higher accuracy and smooth edges are required.
Fineblanking is an advanced metal stamping process used to produce precision parts with tight dimensional tolerances and superior edge quality.
Fineblanking is a specialized form of blanking that combines stamping, shearing, and extrusion operations. It involves the use of a fineblanking press, which consists of a punch, a die, and a counterpunch. The punch and counterpunch work together to hold the material while the die performs the cutting and extrusion operations.The process consists of the following steps:
Feeding: A metal strip is fed into the fineblanking press, positioning it between the punch and the die.
Initial Punching: The punch applies force to pierce a hole in the metal strip. Unlike traditional stamping, where the punch and die meet, in fineblanking, the punch is supported by a ring that surrounds it.
Reduction Shearing: After the initial punch, a secondary punch continues to apply force while the ring restrains the material around the punched hole. This results in a shearing action that cleanly separates the part from the surrounding material.
Coining and Forming: As the punch continues to press against the material, a third punch, known as the pressure pad, exerts counterforce to precisely control the part’s shape and form. This allows for the creation of intricate geometries and tight tolerances.
Ejection: Once the fineblanking operation is complete, the finished part is ejected from the press, while the remaining scrap material is removed.
It is often used in the automotive and tooling industries where precision is of utmost importance.
Types of Stamping Presses
Stamping presses are specialized machines that deliver the necessary force to stamp metals into specific shapes. They are a crucial element in the metal stamping process, with a variety of types available, each offering different capabilities depending on the requirements of the project.
Mechanical Presses
Mechanical presses function by converting rotational motion from a motor into linear motion. This process involves the use of a flywheel, clutch, and crankshaft. When the motor is activated, it drives the flywheel, storing energy within it. The clutch then engages, releasing the stored energy into the crankshaft, which in turn drives the ram to deliver a stamping action.
Mechanical presses come in a variety of sizes and capacities, typically rated by their maximum amount of force, measured in tons. The speed of these presses is measured in strokes per minute (SPM), and they can often reach high rates, making them ideal for high-volume production runs.
One of the advantages of mechanical presses is their high-speed operation and precision. The ram movement’s consistency provides uniformity in the parts produced, a crucial factor in many industries such as automotive and electronics. However, the stroke length and speed are not easily adjustable during operation, which could be a limitation when flexibility is required.
Mechanical presses are often used for blanking, piercing, forming, and drawing. Blanking is a process where the workpiece is cut from the primary metal sheet, while piercing creates holes in the workpiece. Forming alters the workpiece’s shape without removing any material, and drawing involves pulling a sheet metal into a die, producing a raised part.
Despite their advantages, mechanical presses also have certain limitations. They operate at a fixed speed, which may not be ideal for processes requiring varying speeds. Furthermore, the force they apply is highest at the bottom of the stroke, which can limit their effectiveness for certain applications.
On the safety front, while most mechanical presses come with built-in safety systems, improper use or lack of maintenance can potentially lead to accidents. These machines require regular inspection and maintenance to ensure safe and efficient operation.
Hydraulic Presses
Hydraulic presses operate differently from mechanical presses. Instead of converting rotational motion into linear motion, these machines use hydraulic cylinders filled with hydraulic fluid (usually oil) to generate the force necessary for stamping. When the hydraulic pump is activated, it pushes the fluid into the cylinders, forcing the piston to move and thus driving the ram of the press.
One major advantage of hydraulic presses is the ability to deliver a large amount of force over a small area. This is due to the incompressibility of the hydraulic fluid, allowing for a strong and even distribution of pressure. It also enables the press to handle a wide range of materials and thicknesses, making it a versatile choice for applications such as deep draw stamping.
Hydraulic presses are also known for their controllability. Unlike mechanical presses, these machines allow for easy adjustment of force, speed, and stroke length during operation. This flexibility makes them suitable for complex and delicate stamping tasks. However, the speed of hydraulic presses is generally slower than that of mechanical presses, which can be a disadvantage in high-volume production settings.
Servo Presses
Servo presses utilize servomotors in the drive system, which results in highly precise, adjustable speed and position control. Unlike mechanical and hydraulic presses, the energy in a servo press is generated electrically, and the press force and position are controlled in real time by the servomotor. This allows for total control over the press stroke, leading to more versatility in the pressing process.
The advantages of servo presses include the flexibility of the stroke length and press speed, lower energy consumption compared to traditional presses, and improved productivity due to its ability to perform complex strokes and jobs that require precision. They are also quieter and have less vibration, leading to a better working environment.
Servo presses are ideal for jobs requiring a high degree of control and precision. They are used in a variety of applications, such as assembly, clinching, forming, and embossing. The use of a servo press can significantly improve the quality of the final product and enhance the efficiency of the metal stamping process.
Please note, just as in other types of presses, safety considerations should be at the forefront when operating a servo press. Proper training and adherence to safety protocols are necessary to prevent accidents and ensure a safe working environment.
Transfer Presses
Transfer presses differ from other types of presses in that they are specifically designed to move the workpiece from one station to the next during the stamping process. This is accomplished through the use of mechanical ‘fingers’ or other types of material handling equipment.
This process is ideal for the production of complex parts that require multiple stamping operations, such as punching, bending, and deep drawing, to be performed in a specific sequence. The main advantage of transfer presses is that they can execute these different operations simultaneously, leading to higher productivity and efficiency.
Furthermore, transfer presses are highly flexible and can handle various materials and part sizes, making them suitable for a wide range of stamping applications. They are commonly used in the automotive industry for the production of complex and large components such as engine blocks and chassis.
A potential downside of transfer presses is the requirement for larger upfront investment and space compared to other types of presses due to their complexity and size. Nevertheless, the high output rate and versatility often justify this initial investment.
As with all types of metal stamping equipment, safety is a key concern when operating transfer presses. Operators should be thoroughly trained on the equipment and always follow safety protocols to prevent any potential accidents.
What are Stamping Dies?
In the metal stamping process, stamping dies play a vital role. A stamping die is a specialized tool consisting of two parts: the female die and the male punch. The female die is a cavity or recessed area, while the male punch is the component that fits into the die cavity.
How They’re Used in the Stamping Process
Stamping dies are used to shape and cut the metal during the stamping process. When the metal sheet is placed between the female die and the male punch, pressure is applied by the stamping press, causing the metal to take the shape of the die cavity. The male punch exerts force on the metal sheet, allowing for various operations like piercing, blanking, bending, or forming to be performed.
Stamping dies are designed to precisely create the desired shape and dimensions of the final stamped part. They are typically custom-made to match the specific requirements of the project. The design process involves considering factors such as the material being stamped, the complexity of the part, and the required tolerances.
During the stamping process, the metal sheet is fed into the press, positioned accurately, and then the press applies the necessary force to drive the male punch into the female die. This action allows the metal to be deformed into the desired shape or cut into the required pattern.
The quality and precision of the stamping dies are critical to the overall success of the metal stamping process. Well-designed and well-maintained dies ensure consistent and accurate results, minimizing waste and increasing efficiency. Regular maintenance, inspection, and potential repairs or replacements are necessary to maintain the performance of the stamping dies over time.
Stamping dies can be categorized into various types, such as single-stage dies, compound dies, progressive dies, and transfer dies. Each type has its own specific characteristics and advantages, catering to different stamping requirements and complexities.
