The most common mechanism is based upon the Sweet patent. Within the body of the punch, there are three principal moving parts arranged in line: The punch; The intermediate rod (tumbler) The hammer (hammer mass) The hammer mass is spring-loaded from the back of the punch by a large spring. (The spring's preload compression can usually be ...
These mechanisms have many advantages, including reduced part-count, reduced "slop" between joints (no parasitic motion because of gaps between parts [3]), energy storage, low maintenance (they don't require lubrication and there is low mechanical wear), and ease of manufacture. [4]
A coil spring is a mechanical device that is typically used to store energy and subsequently release it, to absorb shock, or to maintain a force between contacting surfaces. They are made of an elastic material formed into the shape of a helix that returns to its natural length when unloaded.
An actuator can be just a mechanism that is directly driven by the motions or forces of other parts of the system. An example is the camshafts that drive the intake and exhaust valves in internal combustion engines, driven by the engine itself. Another example is the mechanism that strikes the hours in a traditional grandfather clock or cuckoo ...
A gas spring consists of a sealed cylinder filled with a charge of high-pressure [5] gas, a piston rod attached to a piston with a sliding seal, and some oil. [1] The piston (or the cylinder wall) contains a number of channels that allow the gas to transfer between the lower chamber (between the piston and the closed end of the cylinder) and the upper chamber (between the piston and the head ...
Mechanisms are mechanical devices designed to transform forces and movement into a desired set of output forces and movement. Subcategories This category has the following 25 subcategories, out of 25 total.
A clockwork mechanism is often powered by a clockwork motor [4] consisting of a mainspring, a spiral torsion spring of metal ribbon. Energy is stored in the mainspring manually by winding it up, turning a key attached to a ratchet which twists the mainspring tighter. Then the force of the mainspring turns the clockwork gears, until the stored ...
