Orbital Forming
Orbital forming is a cold forming process using a peen tool held at a fixed angle to create a sweeping line of pressure around the part, progressively forming the material with each rotation. This process reduces the amount of forming force required by approximately 80% of a standard press.
In orbital and radial forming, the head is formed by a peen attached to a rotating spindle that simultaneously exerts downward force on the workpiece. In roller forming, the peen is replaced with multiple rollers. With the head rotating at 300 to 600 rpm, each pass of the rollers gently pushes and smooths the material into a seamless, solid form. In contrast, an orbital forming operation typically runs at 1,200 rpm.
Press Riveting
Press riveting is an assembly process that uses a hydro-pneumatic press head to apply a downward force to form the material. Press riveting is typically used with 20 mm diameter rivets or larger.
Hot Upset Forming
The hot upset forming and riveting process uses heat and pressure to form the fastener. The material being formed becomes malleable and collapses under pressure applied by the powerhead. Using this process, it is possible to form a round fastener into a square hole, creating very high torque joints. This process is excellent for forming parts that will incur high vibrational fatigu
Impact Riveting
Impact riveting is an assembly process that uses force to permanently fasten two surfaces together. There are a variety of rivet and material possibilities, including solid or semi-tubular rivets. The advantage of impact riveting is the cycle time is fast and the assembly operation is simple.
Radial forming and riveting process
The radial forming and riveting process is similar to the orbital riveting and forming process. But with radial, the material is displaced from the center outward in a rosette or floret pattern. The radial riveting process is often the optimal assembly solution when working with small rivet shank diameters, delicate rivet materials, or unsupported rivet assembly applications.
