Study of dieless radial spinning for thick-walled cylindrical parts with external grooves

Thick-walled cylindrical parts with external grooves are widely used in the automobile and aviation fields. Traditional processes for fabricating such components can’t meet requirements of properties efficiency. The dieless radial spinning process was proposed to produce thick-walled grooves. forming characteristics effects various parameters on were studied by using orthogonal tests finite element simulations. During process, bulge thinning occur because material flow. Parameter study shows that load-yield ratio (ξ) has no significant effect quality. However, feed-thickness (η) initial wall thickness tube (t0) play a crucial role quality (e.g., heights bulges reduction groove area). Different thicknesses differ flexural capacities. inner surface is governed thickness. processing window defined recommend suitable eligible parts.
