Key Driver / Wedge Striker
The NKH Hammers Key Driver (Wedge Striker) is a heavy-duty industrial solution designed for the precise installation, removal and adjustment of wedges in forging and mechanical equipment. It is widely used in metallurgy, mining, construction and machinery manufacturing industries.
By applying controlled hydraulic or mechanical force, the machine ensures accurate wedge positioning, improved equipment stability and reduced manual effort during assembly and maintenance operations.
Working Principle
Workpiece Clamping
The workpiece is securely clamped on the machine bed to maintain stability during operation.Force Application
A hydraulic cylinder or mechanical drive system generates strong pushing or pulling force to insert or extract the wedge smoothly and efficiently.Precision Control
The control system allows adjustment of force and speed to ensure safe, accurate, and consistent wedge installation or removal.
