chrome silicon spring |
A mechanical spring made from steel containing the alloys chromium and silicon. |
chrome vanadium spring |
A mechanical spring made from steel containing the alloys chromium and vanadium. |
deep drawing |
A press operation that creates a hollow recess or cavity within sheet metal. The depth of the recess is greater than the width of the part. |
deflection |
The distance that a spring travels under a compressive force. |
fixed stripper |
A stripper that does not move within the die set. Fixed strippers strip the stock from the punch, but they do not hold down the stock during operation. |
floating stripper |
A stripper that is designed to move as press ram reaches the bottom of its stroke. Floating strippers hold down the stock during the stamping operation and strip the stock. |
ISO |
The International Organization for Standardization. ISO establishes standards and guidelines for various products and processes. ISO standards often contain metric units. |
mechanical spring |
A spring consisting of a coil of metal with a hollow center. Each mechanical spring is categorized according to the compressive force it can withstand. |
mechanical spring stripper |
A stripper consisting of a stripper plate and mechanical springs. |
nitrogen spring |
A spring consisting of a cylinder containing compressed nitrogen gas that applies pressure to a moveable piston. |
nitrogen spring stripper |
A stripper consisting of nitrogen springs, which are hollow cylinders containing compressed nitrogen gas. |
preloading |
The intentional compression of a spring before it is used in an operation. |
spring |
A device that yields under a compressive force and returns to its original shape once the force is removed. |
stripper bolt |
A bolt used to attach the stripper plate to the upper or lower die shoe. Mechanical springs may be fitted over the stripper bolt. |
stripper plate |
The metal plate that contacts the sheet to strip it from the punch. Stripper plates are commonly made from steel. |
stripper system |
The assembled components within a die set responsible for stripping the stock from the punch as it retracts. |
urethane stripper |
A stripper consisting of a hollow, cylindrical spring made from urethane rubber. The urethane spring bulges under compressive force. |
