Abstract
The utility model discloses an air control C-shaped circle mechanical expansion and shrink shaft which is used for metal and nonmetal foil and film shaped coiled materials and suitable for production of aluminium strips and foil. In order to solve the problem that an existing air bag and slant-to-slant type mechanical expansion and shrink shaft is rootless and low in precision and structural intensity in corrosion of a compressible and slant expansion block of an expansion strip, a slant-to-circle novel structure which has self retraction ability is proposed to replace a slant-to-slant typical old structure. The air control C-shaped circle mechanical expansion and shrink shaft comprises a main shaft pipe and an expansion and shrink mechanism which is formed by combining of a C-shaped circle and a plurality of cone wedge pipes which are symmetrically sleeved on the expansion and shrink mechanism. Opposite-direction advancing of the cone wedge pipes enables the C-shaped circle which has a plurality of anti-sliding blades to externally expand, wherein the C-shaped circle is sleeved on the cone face, so that the C-shaped circle becomes mechanical secondary reinforcement. Therefore, coiled core pipes are clamped tightly. The radial size of the slant-to-circle structure is small, and strength of an expansion shaft is improved. In the process of tightly clamping, and radial run-out-error of a shaft is reduced due to the fact that a gap between a blade and a shaft disappears. The air control C-shaped circle mechanical expansion and shrink shaft is suitable for production of batching of a thick pipe core and a wide format.
