Detailed description of the invention
For making the present invention become apparent, hereby with a preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Composition graphs 1 ~ Fig. 3, the invention provides a kind of cylindrical die of outer radius variable, is made up of support tube 1, driving link 2, left connector 3, right connector 4 and outer wall 5.
Composition graphs 4, support tube 1 has certain thickness, support tube 1 has inclined hole 11, and inclined hole 11 is along the distribution of support tube 1 even circumferential, and distributes vertically.
Composition graphs 5, outer wall 5 is divided into main part 53, skewback 52, baffle ring 51; Main part is circumferentially evenly cut by the cylindrical drum that internal diameter is identical with support tube 1 external diameter to form; Skewback 52 has multiple, is positioned at main part 53 inner surface centre position, and skewback 52 can cooperatively interact with the inclined hole 11 on support tube 1; Baffle ring 51 is separated along its circumference by circular baffle ring, is positioned on the outer surface of main part 53.
Outer wall 5 coaxial sleeve is outside support tube 1, and along the distribution of support tube even circumferential, the outer wall quantity along support tube circle distribution is more than or equal to three.Skewback 52 is positioned at inclined hole 11, thus makes outer wall 5 coordinate with support tube 1 and to move along support tube inclined-plane 11.Outer wall 5 number is identical along its circumferencial direction equally distributed inclined hole 11 number with on support tube 1, and like this, when the inclined hole on outer wall on skewback and support tube cooperatively interacts, the figure of multiple outer wall outer surface composition is the face of cylinder or approximate circle cylinder.
