Tool and Die changing

Pneumatic Die Rollers

To change press dies without support by Die Lifters with rolls needs, depending on the weight of the press die, very strong forces. Thereby already the change of smaller press dies by the operator is a show of strength. To change bigger press dies without support by Die Lifters with rolls or balls is nearly impossible.

Die Lifters with Balls allow a multi-directional movement of the die and give the bestpossible manoeuvrability. Caused by their smaller load capacity as well as their punctual contact to the press die (increased wear at the bearing surface at the bottom side of the press die) they normally are used in case of smaller die weight only.

Usual for purpose of die change therefore is the use of Die Lifters with Rolls, also in case of heavy die weights. Die Lifters with Balls are available with hydraulic as well as pneumatic lifting installation.

Pneumatically operated Die Lifters with Rolls do have the these advantages:
+ simple installation within existing T-slots without
workintensive and expensive hydraulic installation + Their construction principle allows the use of bigger rolls
+ best possible weight distribution onto a lot of big rolls
+ low friction only, thereby protection of the bearing surface of the die
+ lower purchase cost

Pneumatically operated Die Lifters with Rolls are available for T-slots indicated below :

T-Slot-Dimension       Load Capacity      max Load Capacity at
                                   at 6 bar                  max 12 bar working pressure
T22             1.300 kg / Meter           2.600 kg / Meter
T28            1.700 kg / Meter           3.400 kg / Meter
T36            2.700 kg / Meter           5.400 kg / Meter

Usual working pressure: 6 bar

The working pressure within the pneumatically operated Die Lifters with Rolls can be increased by means of the available pressure intensifier. By this the load capacity can be increased up to the double value.

Using the corresponding T-Slot-Housing, pneumatically operated Die Lifters with Rolls also can be screwed onto Die Change Tables and thereby can build an excellent bearing surface for manoeuvring of heavy dies.
Including suitable control pneumatically operated Die Rollers with different driving directions can be activated, so that the dies can be moved in any desired direction.

For change of very heavy press dies, which even on pneumatically operated Die Lifters with Rolls can be moved manually only very difficult (weight bigger than 5 tons), the system consisting of pneumatically operated Die Lifters with Rolls additionally can be equipped with the Die Moving System "Mark II". With the Mark II system it will be possible to move heavy dies into / out of the press and onto the stationary die change table by pushbutton.
Detailed information regarding the "Mark II Die Moving System" you will find on our page "Die Change Drive".

Pneumatic Die Rollers / Die Lifters with Rollers or Balls.
For Die Changing.
Simple installation at existing T-slots without work intensive and expensive hydraulic installation.
Rollers with larger Diameter can be used compared to hydraulic Die lifters. This also gives less friction and less force to push / pull the tool at the Die Change.
Installation only takes a few minutes and you do not have to worry about leaking hydraulic oil.
