Details for Toggle Presses
Definition, Function, Use
toggle presses are manually operated bench-top presses. Like all toggle presses the press force is generated with manual force applied to the lever, which starts up the transmission mechanism. The specialty of the toggle press is that while the long hand lever remains constant, the smaller lever is shortened during the press stroke so that at the end of the stroke the manual force applied generates a large amount of press force.
The maximisation of compressive force is caused by the double, moveable suspension of the connect-ing lever, which is located between the toggle lever and the plunger. That is why toggle presses are also called indirect-acting presses. The plunger conducted into the long, precisely honed plunger hole exerts a linear movement and transfers the force to the work piece. A spring, which is made taught with the stroke, not only makes the easy back-stroke of the press possible, but also gives the operator a feeling for the movement being executed through its initial tension. The factory precise adjusted limit stop ensures that the dead point of the press cannot be over-pressurised..
The position of the press head is infinitely adjustable using the controls on the press stand. This makes it possible to adjust the work height to accommodate the inserted tools and parts.
The exponential power flow towards the stroke end of toggle presses make them the ideal tool for work steps wherein full force is needed at the end of the stroke, for example for flanging, caulking, riveting, stamping, labelling and similar tasks.
toggle presses are ideal for flexible application in the most different industrial branches and for the use of various different tools and parts. Typical areas of use are in the building of prototypes or the production of smaller and medium lot sizes, whereby a full automation would exceed the budget.
