We will customize its width of RAM and shut height by your order for your new press.
The frame is a one-piece, stress-relieved casting with the sides extendedat the rear in box-form sections, which are utilised as air receivers.
Air piping for the clutch and brake systems is thus kept to a minimum,avoiding unnecessary air losses.
The casting is subjected to a rigorous code of inspection at all stages of production using the most modern methods.
All bearing surfaces are machined and machined and protected by replaceable bushes or liners. The base is also machined to ensure a good bed on the foundation.
For a given weight of frame the one-piece design has the shortest possible elastic circuit and provides the maximum effective cross-sectional area between the eccentric shaft bearings and the table.
Dynamic balancing of the ram and connecting rod assembly is effected by air cylinders, which automatically counterbalance the ram so that contact is maintained between the bearing surfaces throughout the working stroke. Static balancing is sufficient when ‘inching’ or slow running but dynamic balancing is required to maintain contact at high speed when approximately double the balancing forces are needed.
Two roller bearing assemblies, which support the eccentric shaft at each side of the frame, are pneumatically loaded and pre-load the main bearings so that the shaft is held firmly against the upper halves of the bearings at all times. Coupled with the dynamic balancing of the ram it takes up the beraing clearances in the connecting rod and eccentric shaft and provides the following advantages ;
