Title: John W Daines: Innovator in Friction Bonding Technology
Introduction
John W Daines is a notable inventor based in Bristol, GB. He has made significant contributions to the field of friction bonding technology, holding a total of 4 patents. His work has been instrumental in advancing methods for attaching components in various engineering applications.
Latest Patents
One of his latest patents is the "Friction bonding clamp for a rotor blade." This invention describes an apparatus and method for attaching individual blades to a disc rotor of a BLISK. In this process, blade blanks or preforms are gripped between adjustable jaws of a rigid frame member of a linear friction bonding machine. The attachment occurs in a non-rotational friction bonding operation, allowing for the blade preforms to be finished to their final airfoil shape in a subsequent operation. This technique is particularly suitable for both repair work and original manufacturing.
Another significant patent by Daines is the "Friction bonding apparatus." This invention addresses the challenge of gripping delicate or awkward components that need to be friction bonded. A flange or similar formation is formed on the component, allowing it to be gripped firmly through a wedging action. The component is then loaded into a shuttle equipped with a releasable wedge clamp, which is carried by the output drive member of a friction bonding machine. The necessary machine forces for friction heating and bonding are transmitted through faces on the shuttle that abut the component flange.
