Closed Single Point Press Machine
Closed single point press machine is a type of mechanical pressing machine which is used to create a pressing force action on a work material. Closed single point presses can be used for a number of applications, such as plastic molding, stamping, forming and forging.
Closed single point press machines have a stationary bed, a moving ram which is driven by a toothed rack and pinion drive, and a fixed top platen. The pressure applied is transmitted via the toothed drive and a set of dies mounted on the ram. The main types of closed single point presses vary in their size and capacity, and include flywheel (or crank) operated machines, crank-shaft machines, mechanical clutches, and hydraulic presses.
The flywheel operated machines are the most common and feature a large stop flywheel which provides the force to drive the ram. The crank-shaft machines use a crankshaft and linkages for providing the power. Mechanical clutches are also used for some applications and use pulley and belt drives to operate the machine.
The force applied in a closed single point press machine is generally limited to the capacity of the press and the tonnage rating, which is determined by the size of the dies and the stroke of the pressing machine. Presses of higher capacity are generally used for larger tonnage operations, while those of lower capacity are used for smaller operations with lower tonnage.
Safety is an important consideration when using closed single point press machines. These presses must be properly supervised and inspected to avoid accidents. All work performed with a closed single point press should be done following the manufacturer’s instructions, and all safety devices should always be in place and checked before operating the press.
In conclusion, closed single point press machines are a type of mechanical pressing machines which are used for a wide range of applications, from plastic molding to forging. These mechanical presses must be operated with care and proper supervision to avoid any accidents or injuries, and all safety requirements should be followed for the safe operation of these machining tools.
