Method for expansion of thick walled sleeves, preferably of circular cross-section and expanding tool for application of this method

摘要

a pushing sleeve grubou015bciennych, especially of circular cross-section, is that we will walk is rozpychaju0105cym tool (2), with the tip of the working party (3) with obru00f3bczymi parts in the form of a path (4), connected through the central part of cfcs tau0142tuju0105cu0105 (5) with a part of kalibruju0105cu0105 (6) and the surfaces obwodowymi parts (4, 5, 6) of the actuator (3),combined bezstopniowo, and the peripheral part is (5), would help to the longitudinal axis (7) rozpychaju0105cego tools (2) in an angle (?) part a (4) fit to suwliwie or slightly luu017anie with axial hole initial work cores.the size of the angle (?) the peripheral part is (5) varies depending on the work material cores. the transverse dimension of kalibruju0105cej (6) fits to the required transverse dimension for the axial hole final work cores, preferably with regard to her spru0119u017cynowania phenomenon.the subject of the invention is also a tool to rozpychaju0105ce cores, particularly for wheeled grubou015bciennych cross-sections. the invention applies especially to the pushing tube grubou015bciennych with large naddatkami on treatment and tulejek metal rubber with initial stress, used for example in the automotive industry and machinery.
