Sheet Metal Blanking: The Science Behind It
The science behind sheet metal blanking is complex, even though it may seem simple.
Metal Deformation: Principles and Mechanisms
Plastic and Elastic Deformation
The first time a metal is deformed, it experiences elastic deformation. This is a temporary change in which the metal returns to its initial shape after removing the force. If the force applied to a metal goes beyond its elastic limits, it will cause plastic deformation.
Yield strength and ultimate tensile strength
Each metal has a Yield Strength — the maximum stress it can withstand without permanent deformation. When you stress metals beyond their yield strength, they begin to deform plastically—the point where a metal breaks is its Ultimate Tensile Strength.
Work Hardening
Metal undergoes plastic distortion, which causes it to become more robust and more complex. This phenomenon is known as strain hardening. This is important in blanking, as repeated blanking can change the metal’s properties.
Factors Influencing Sheet Metal Behavior
Material Composition
Metals differ in their atomic structure and composition. Metal alloys, impurities, and grain arrangement can all significantly impact the deformation of a metal. It’s easy to blank metals like aluminum, but harder metals like stainless steel need more force.
Direction and Size of Grain
Metals consist of tiny crystals, which we call grains. The size and orientation of these grains largely determine metal properties. Finer grains produce a stronger and more ductile metal, allowing for a smoother blanking process.
Temperature
The temperature can significantly impact a metal’s behavior when blanking. Metals become more ductile at higher temperatures, and this facilitates the deformation. The principle of hot working is based on this. However, metals usually work at room temperature during blanking, also known as cold working.
Sheet Thickness
The thickness of a metal sheet is crucial to the blanking procedure. The blanking of thicker sheets requires more force. As the thickness of the sheet increases, so does the possibility of defects or irregularities on the edges.
Residual Stresses
The blanking process can be affected by residual stresses in metal sheets resulting from previous manufacturing processes. These stresses can cause unexpected deformation or warping during the blanking process.
Blanking Machines & Equipment: A Deep Dive
Blanking machines are available in different types.
Mechanical presses
Mechanical presses were traditionally the primary tool for blanking. These machines use a mechanical flywheel for storing energy. From there, a clutch transfers it to the punch. These machines are suitable for blanking jobs that require high volumes of blanking.
Hydraulic presses
Hydraulic presses use fluid-filled hydraulic cylinders to create the force needed for blanking. They are ideal for blanking thicker, more complex materials because they can control the speed and power of the press with precision.
Servo Presses
The servo press is an improvement over traditional mechanical presses. It uses servo motors for the slide movement. The system is flexible because you can adjust the stroke lengths and speed to fit different blanking requirements.
High-Speed Blanking Machines
A high-speed blanking machine is the best choice for operations that require rapid production rates. These machines have been designed to run at higher speeds per minute and are, therefore, suitable for environments requiring mass production.
Safety Features and Design Improvements
Light Curtains
Light curtains demonstrate that safety is paramount. These photoelectric transmitters are positioned around the blanking machines and shoot light beams. The device will stop immediately if any object or person interferes with the light beam.
Pressure Sensitive Mats
These mats are placed around the machine and feel pressure (like someone stepping on them). They shut off the engine immediately when they detect pressure.
Dual Palm Button Controllers
Many blanking machines are now equipped with two palm buttons to prevent accidental machine operation. To operate the machine, one must simultaneously press both buttons. This design keeps hands safe from any moving parts.
Quick Die Change Systems
In production, time is crucial. Modern blanking machines have systems for quick die changes, cutting the time between tasks.
Integrated Monitoring Systems
Modern blanking machines have monitoring systems that continuously monitor the machine’s vital parameters. Alarms are triggered if any deviation from regular occurs, which allows for timely intervention to prevent damage or failure.
Ergonomic Design
Modern machines place a high priority on operator comfort. Operators can work longer without strain with ergonomically designed controls.
The Sheet Metal Blanking Process – Step-by-Step
Selection Sheet Metal
Material Exam
Each project thoroughly analyzes the sheet metal types, considering strength, elasticity, and corrosion resistance characteristics. The choice of alloys, whether malleable aluminum, robust stainless steel, or any other, depends on the requirements for the final product.
Thickness consideration
The thickness of sheet metal is crucial to the blanking process. Sheets can be very thin foils or thicker plates, depending on the final dimensions of the product and structural requirements.
Machine Preparation and Setup
Die and Punch Selection:
Die and punch combinations are the heart of blanking. A die and punch combination is selected or manufactured based on the component’s design. The punch pushes the metal sheet through the die.
Machine Calibration
Calibration is essential, whether you are using hydraulic presses or mechanical presses. The technicians ensure that the press exerts enough force depending on the type of metal and thickness. This step is crucial to achieving a clean cut and minimizing defects.
Sheet Metal Positioning:
The sheet metal must be placed on the blanking machine precisely before the actual blanking can begin. The placement of the sheet metal is precise to ensure efficient use and minimal waste.
Lubrication:
Sheet metal and cutting tools are often lubricated to prevent excessive machine wear and ensure a smoother process. This reduces heat and friction during the blanking procedure.
Punching & Cutting Process
Starting the Blanking Stroke
The blanking press can be activated once everything is ready. The punch is moved downwards and pushes the sheet metal into the die. This action shears metal and creates desired components.
Ejection Blank
The punch pulls back once the blank forms, and the effectiveness descends fully. This allows the blank to be removed or ejected from the die area.
Inspection and Quality Control
Each blanked part is inspected thoroughly to verify that it meets all design specifications. Shengen prioritizes quality. We send any component that doesn’t meet our high standards for reworking or recycling.
Collection of Scraps
After blanking the sheet metal, it’s gathered up. These scraps are recycled into new sheets or used in minor processes.
