Claims (1)

[Scope of Claim for Utility Model Registration] (1) A die block that is detachably attached to a predetermined position on a machine base and holds a plurality of dies ranging from coarse to fine in parallel at regular intervals, and a die block that is detachably attached to the machine base. A chuck block is attached to the chuck block and supports the same number of material transfer chucks as the dies so as to be able to reciprocate in the direction in which the dies are arranged side by side, and the ram is detachably attached to the ram which is equipped on the machine base so as to face the die blocks. and a punch block to which the same number of punches as the die are fixed, an automatic tool changing device for a multi-stage heading forming machine, wherein a changing station is provided on the side of the machine base, a conveyor that travels on a conveyor rail constructed above the exchange station and the machine base so as to straddle them, and conveys each block between the exchange station and the mounting position of each block on the machine base and ram; A turntable for each block is disposed on the exchange station, and a turntable for each block can be placed on each of the blocks and replacement blocks for exchanging each of these blocks. An automatic tool changing device for a multi-stage molding machine, characterized in that the turntable is rotatable and slidable to a position where each block can be transferred to and from the conveyor. (2) The chuck block, the die block, and the punch block are each removably attached to predetermined positions on the machine base and the ram by hydraulically driven fixing means, and the carrier has an engaging portion with each block, An automatic tool changing device for a multi-stage heading forming machine as set forth in claim 1, wherein the engaging portion is configured to be driven by hydraulic pressure. (3) The automatic tool changing device for a multi-stage heading forming machine as set forth in claim 1 of the utility model registration, characterized in that the installation portion of each turntable in the changing station is a tool storage. (4) The die block turntable and punch turntable at the exchange station are
The die block and punch block placed on each block are placed in close proximity to each other so that they can be moved to a position where alignment adjustment work can be performed between a plurality of dies and punches respectively installed on each of these blocks. An automatic tool changing device for a multi-stage heading forming machine as set forth in claim 1 of the patented utility model.
