Materials and Processes
Review the following jaw die clamping wedge material and process information when assessing specifications and alternatives.
Alloy Cast Steel
Verify clamping wedge material, heat treatment and hardness against the part drawing. The wedge face must fit the jaw plate backing accurately; contact and preload must meet the model-specific assembly specification.
Fastening system
The fastening system includes clamping and fill wedges, hammer-head bolts, spring assemblies, washers and nuts. Metso offers fastening kits; confirm the kit contents for the specific machine.
Installation considerations
Ensure the jaw plate backing faces seat fully against the frame or pitman, with even wedge contact. Tighten bolts progressively to the specified torque.
Wear and Replacement Criteria
Use the following clamping wedge wear patterns and replacement considerations during maintenance.
Main failure modes
Wedge-face wear, bolt-thread wear or breakage, and spring fatigue.
Replacement Criteria
Wedge wear that prevents effective jaw plate clamping, damaged bolt threads, or spring failure causing inadequate preload.
Recommended Actions
Inspect wedges whenever jaw plates are replaced. Check bolts and springs for damage and tighten bolts to the specified torque.
Information Needed for an Inquiry
Equipment model, such as C100; part number; clamping or fill wedge; whether a fastening kit is required; and quantity.
