Problems solved by technology

In particular, when rotating at a high speed to improve manufacturing efficiency, it is necessary to increase the tension of the timing belt, and the radial load caused by this tension will incline the posture of the rotating laminated mold, reducing the rotation accuracy of the rotating laminated mold. Reduce the manufacturing accuracy of the motor core

Abstract

The present invention provides a rotating-layering mold whereby a punched sheet is rotated according to a prescribed angle and layered by an upper mold and a lower mold working in tandem, and providesa press apparatus comprising the rotating-layering mold. A rotating-layering mold (201) comprises a squeeze ring (202) in which is provided a retaining hole (203) for retaining a punched sheet, the squeeze ring (202) being capable of rotating with respect to a lower mold (105) so that an upper outer circumferential surface (211) of the squeeze ring (202) lies along an inner circumferential surface (109) of the lower mold (105). The rotating-layering mold (201) further comprises a first thrust bearing, a second thrust bearing, and a radial bearing in order to support the rotation of the squeeze ring (202) with respect to the lower mold (105).

Description

technical field [0001] The present invention relates to a rotary lamination die that rotates and stacks sheet materials punched out by cooperation of an upper die and a lower die at a predetermined angle, and a press device provided with the rotary lamination die. Background technique [0002] A plate-shaped rolled steel sheet is supplied between an upper die and a lower die of a press device in a state of being rolled and wound into a roll, and punched into a predetermined shape by cooperation of the upper and lower dies that can slide up and down. Furthermore, the rotary lamination die is used to laminate punched plate-shaped rolled steel sheets to form a rotor, a stator, and the like called a motor core. However, when the rolled steel sheet is rolled, there is a slight difference in the width direction because the pressure on the support portions of the rolling rolls at both ends in the width direction is different from the pressure at the center of the rolling rolls in t...
