The History of The Stamping Press
Most people point to the 19th century when discussing the origins of the metal stamping press. Before this time, most stamping and metal forming were performed by hand-operated mechanisms, but as populations grew and demand increased, so did the complexity and capabilities of these machines. In the late s, presses powered by steam were developed. These early developments dramatically improved manufacturing operations' productivity, precision, and efficiency.
The 20th century introduced even greater machine capabilities when flywheels and electric motors were incorporated into stamping presses, allowing for dramatically faster production of metal components. Over the years as enhancements and innovations improved, the modern mechanical and hydraulic presses that we know of and use today were developed. These newer machine iterations offer greatly enhanced precision, productivity, control, and efficiency. Early into the 21st century, the servo press was introduced to the manufacturing world drastically furthering what could be accomplished in stamping.
The stamping press's evolution has helped manufacturers keep up with the needs of the modern highly demanding and technological society. Today, stamping presses are more versatile and efficient than ever, thanks to the ongoing improvements that accommodate various materials and complex geometries. The evolution of the stamping press has helped them remain as a key component in modern manufacturing environments by empowering industries with greater production capabilities and finer control over quality.
How Stamping Presses Work
A stamping press functions by converting rotational motion into linear motion, using force to form or cut sheet metal into desired shapes. The press uses a die&#;a specially designed tool&#;to shape, cut, or punch materials, such as steel or aluminum, to create specific components. The combination of speed, force, and precision allows stamping presses to produce large quantities of identical parts rapidly and efficiently.
The stamping process involves three key stages: feeding the material, forming the material, and removing the finished product. Raw metal is fed into the press, where the machine&#;s ram moves down with force, shaping or cutting the metal through the die. Depending on the type of stamping process&#;such as blanking, coining, or drawing&#;the press can create different parts with high repeatability and accuracy.
Anatomy of a Stamping Press
Becoming familiar with their main components is important to better understand stamping presses.
Frame
This is the main structural body that holds all other components in place. The frame must be robust enough to withstand the dynamic forces produced during stamping.
Press Drive Mechanism
The Drive mechanism of a press powers the movement of the ram. Based on the type of press, it can be mechanical, hydraulic, or servo-driven. From there the classifications are then broken down even further based on the type of connection between the drive and the ram, which we plan to discuss in a future article.
Ram
The moving part that applies force to the die and forms, cuts, or punches the material into the desired shape. It is powered by a drive system, which as mentioned above depending on the type of press machine can be mechanical, servo, or hydraulic.
Press Controls
The PLC (Programmable Logic Controller) allows the operator to program and monitor the operation of the press. Today state-of-the-art presses come with digital controls that have provisions and functions to make stamping more accurate and consistent, while also keeping operators informed about the status of the machine.
Die Set
The tool that gives the desired shape to the workpiece. Dies are typically comprised of an upper and lower portion with the upper portion mounted to the ram and the lower portion mounted to the press work table or bolster plate. Stamping dies can be custom-made for each specific part to be manufactured.
Work Table/Bolster Plate
The fixed lower part of the press, where the lower half of the die is mounted and withstands the working force. For some stamping operations, the scrap or complete parts fall through an opening in the bolster, which can be customized based on the needs of the user.
This is not an exhaustive list of press components and parts, as many other elements of a press are crucial to their operation, but this serves as a good starting point for those who are new to this type of machinery.
