BRHF and BRHB type fixed and tilting

The BRH range is mainly designed for clamping the bottom parts of dies and rolling bolsters. However, it is possible to install these products on the slide. Clamping is centred around a double acting hydraulic cylinder that deploys a tractive force on the clamping hammer.

Two models are available. The first version is fitted with a fixed rod
attached to the traction piston. The second is fitted with an articulated rod that retracts by rocking to allow the dies to be removed.
These clamping systems present the advantage of fitting into the thickness of the bolster or the ram face.

Their operation requires a hydraulic power source and an actuating
distributor. These accessories can be supplied separately.
It is essential to follow the operating rules.

BRM_C type movable


In the event of mechanisation, BRM_C type clamps are moved
by pneumatic cylinders fitted into the slots.
A sensor monitors the position against the die and authorises
clamping by releasing the hydraulic pressure.
Mechanisation of the clamps allows automatic management
of die clamping and release operations.

BRI type impact

BRI impact clamping is a die clamping system that is a standard
in industry (mainly the automobile industry). It provides rapid
clamping and release of dies on large and medium drawing
presses.
This quick-clamping system has a hammer holding clamping force
of 70 kN and a lifting force of 50 kN. An independent electronic
control unit contains the control data providing a very high degree
of accuracy in clamping and release operations.
It is very quickly operational on site, being set and calibrated
on a test bench in our works before delivery.
