A part’s strength is defined by how much stress the part can take before it begins to fail or break. Excavators, backhoes, tractors, combines, conveyors, trucks… Heavy equipment components must have the strength to endure the most punishing environments. This is why there is more to a forged gear than the initial price tag.
A cheaper part does not always equal cost savings, especially if the component does not perform consistently during machining and equipment performance. Fortunately, there are cost-effective, turnkey forging techniques that can dramatically increase strength for more durability and reliability.
Metallurgy matters when it comes to how well an axle flange or drive gear will hold up for workhorse machinery like an off-road pickup truck or an excavator. An experienced engineer can design the process to ensure the grain flows, microstructures, and final mechanical properties in steel forgings create consistently stronger parts for more reliable, consistent performance.
These metallurgical factors can:
Multiple types of heat treating techniques exist that are designed to enhance the performance of steel, whether the goal is increasing strength, toughness, or machinability. These techniques can further enhance steel’s metallurgical properties in ways essential to heavy equipment components, such as drive and bevel gears.
Heat treating processes applied to raw forgings include:
In some cases, heat treating steps can be eliminated utilizing conveyor/controlled cooling. After hot forgings come off the press and are trimmed, they are cooled in still or accelerated air on conveyors to a specified temperature. This process is ideal for parts made from certain micro-alloy steels, or where the primary goal of heat treating would be to generate consistent machining characteristics.
A full-service forger can meet specific customer requirements for mechanical properties by selecting the appropriate heat treatment for each part. This means the forger can accommodate a wide variety of customer requirements.
Expected part performance should be assessed prior to part installation, or even machining. A variety of techniques exist to predict and assure product capability.
These testing techniques include:
These methods are used to ensure parts consistently meet performance criteria batch after batch, whether those criteria are simply consistent machining characteristics or in-service durability.
Presrite can design forgings that can reduce machining cycle times by minimizing excess material stock and maximizing machining consistency. Presrite forgings also maximize product strength to weight ratios by having superior grain flow and inherent strength than other manufacturing methods.
