Title:
MULTISTAGE HEADING MACHINE
Document Type and Number:
WIPO Patent Application WO/2005/075128
Kind Code:
A1
Abstract:
A multistage heading machine capable of manufacturing micro parts without producing defective transportation and defective molding by swinging the chuck of a carrying means at an accurate stroke. A drive mechanism (85) operating a swing mechanism is disposed on a first drive shaft (88) forwardly and reversely rotated by the forward and backward movements of a drive rod (86) so that an operating member (89) can be rotated integrally with each other. An eccentric shaft (90) is disposed in the operating member (89) eccentrically from the first drive shaft (88), and the eccentric shaft (90) is swung in an arc shape as the first drive shaft (88) is rotated in the forward and reverse directions. The connection member (78) of the swing mechanism is connected to a sleeve (91) fitted onto the eccentric shaft (90), and the chuck swings between adjacent dies according to the swing movement of the eccentric shaft (90). Since a separate distance (L) between the axis (C5) of the first drive shaft (88) and the center (C4) of a through-hole (78a) in the connection member (78) is changed by rotating the eccentric shaft (90), the swing stroke of the chuck can be adjusted.
