Clamping
We offer a variety of clamps for both standard and exceptional working environments. Clamping and unclamping of dies is automatic or with minimal manual intervention.
The essential qualities of a clamp are the speed of opening and closing, and the ease of inserting and removing. Our comprehensive range of clamps will offer the best solution for your application.
The clamping force
It should at least be equal to the opening force of the ram – approximately 10% of the striking force in common applications. The clamping force is the same on bolster and ram. Divide this force by the number of clamps to be used on either part, bolster or ram, to obtain the capacity of each clamp. For large and heavy dies, and for high strike rates
(above 200 per minute), consider the relevant amount of inertia on moving the ram. For this, please contact our technical support.
Standardisation of tools
Is the key to efficient clamping, especially when automation is desired. But even without standardisation, SERAPID clamps will still improve efficiency. For all dies in use, the following parameters should be the same:
- dimensions of die plates
- clamping stroke
- clamping positions
This basic data is necessary to select the right type of clamp:
- Fixed clamp TBH (080-01*)
- Removable clamps BTSA (040-02*) / BTSC (040-07*)
- press tonnage and opening force in Newton [N]
- weight of dies in kg
- press stroke in cost / minute
- die change frequency in nombre /day
- space available for clamps on bolster and ram
(dimension)
Clamping elements can be either fixed or removable.
