Home About Us Why Nelson? Problem Solving Capabilities Contact Us Punch Press/Stamping Punch press and turret punch press machines are part of Nelson's complete steel fabrication repertoire. Coil Feed Lines (up to .179" x 31") Progressive dies and manual blanking Stamping Unitized Tooling for lower tooling costs CNC Punching Up to 400 ton with a 10' bed Punch presses, turret punch presses (with several tools) and stamping presses are other workhorses of a steel fabricator. In a punch press, sheet metal is sized or shaped as pressure is applied to a die holding the material. The resulting configuration depends on the form and construction of the die. In a punch press, two components work together to create the desired shape. The punch is attached to the ram of the machine. The die is clamped onto a flat bed or anvil perpendicular to the ram. As the machine operates, the punch exerts pressure on the stock material held in the die. Blanking dies produce slugs of sheet metal to make blanks to fit dies for later punch-press operations. Punch presses range from small manually operated units to large powerful machines operated by computer numerical control (CNC). Regardless of the size, however, all punch presses use a die set to complete the punching process. Male punches and female dies make up a die set. As these pieces come together during the machine cycle, the sheet metal is shaped or cut into the predetermined form. Skilled craftsmen design the die set and set up the machine for production. Even though it may take considerable time to prepare a punch press, once properly set up, it is equipped for high-volume production, and one operator is capable of tending more than one unit. Capacities of punch press are measured in tonnage. Stamping presses also shape or cut metal through a process of deformation with a die. The bottom portion of the die is clamped to the bed or the press, which is essentially a large metal block. The bed remains stationary throughout the machine cycle. The other half of the stamping die is affixed to the ram which moves through an up and down cycle, producing parts from the sheet stock fed through it. Stamping presses are either mechanically or hydraulically driven. In many cases, presses are linked electronically with automatic feed units which keep raw material flowing through the die. As you can see from the capacities data given above, Nelson Steel Products is well equipped to meet customer needs for fabrication requiring punch presses, turret punch presses and stamping machines. 410 East 48th Street Holland, MI 49423 Phone: 616-396-1515 Fax: 616-396-5942 © 2021 Nelson Steel Products.
