摘要： The invention is concerned with a method of forging a part of a predetermined shape from a workpiece comprising the steps of: radially closing opposed forging dies such that the forging dies move radially inward in a predetermined direction to contact the workpiece wherein the opposed forging dies define a cavity therebetween of the predetermined shape of the resulting part; applying axial and radial force to the workpiece with the radially closing forging dies, said applying step including the step of generating compressive and shear stresses within the workpiece such that the workpiece deforms outwardly to the predetermined shape defined by the opposed forging dies; and structurally reinforcing the opposed forging dies during the application of compressive and shear forces with a die housing which receives and circumferentially encompasses the opposed forging dies during the forging process.

摘要： A "snap-in" bit chuck assembly (10) for a rotary hand or powered tool, includes a body (20) having a hex shank (22) at its rearward end, a retraction collar (30) slidably disposed on the body, and an outer retaining collar (70) fixed to the forward end of the body. A polymeric cover (38), formed by a two-step process, is retained on the periphery of the retraction collar. The polymeric cover includes a molded base layer, over which an outer layer is molded, with the base and outer layers being preferably of contrasting colors and with a portion of the base layer protruding through the outer layer. This protruding portion of the base layer is flush with the outer surface of the outer layer so it can be used to display an indicia of the manufacturer of the chuck assembly.

摘要： A 'snap-in' bit chuck assembly (10) for a rotary hand or powered tool, includes a body (20) having a hex shank (22) at its rearward end, a retraction collar (30) slidably disposed on the body (20), and an outer retaining collar (70) fixed to the forward end of the body (20). The body (20) has a coaxial hex socket (24) formed therein to allow a tool bit (14) to be inserted thereinto. A slot (50) is formed in the body (20), between the outer surface of the body (20) and the internal hex socket (24). A coil spring (40) surrounds the body (20), inside the retraction collar (30), and normally biases the retraction collar (30) forwardly and biases a retaining clip (60) toward the bottom of the angular slot (50).
