Embodiment Construction

[0030] The embodiment of the multi-stage molding machine 8 shown in FIG. 1 includes four molding stations from which one mold 81, 82, 83, and 84 can be seen. These molds 81, 82, 83, and 84 are supported in a fixed mold frame 85 which is indirectly connected to a frame 86. In order to transport the workpiece 9 to each forming station and then transport it away from there, a workpiece transport device with four clamps 1 is provided. The clamps 1 can move laterally on the one hand, for which purpose they are mounted on a lateral conveying assembly 4 which can be laterally moved by means of a lateral conveying pipe. On the other hand, the clamp 1 can be opened and closed and can be raised or lowered at the same time, which is achieved by a mechanism which will be described in detail below. In order to open or close the clamp 1, a driving rod 3 that is movable in the longitudinal direction is provided, and the driving rod is longitudinally movable by means of an adjustment mechanism 5,...

Abstract

A work transport device for a metal-forming machine comprises a pair of grips (1) which have two non-crossing gripper arms (11, 12) which are pivotable relative to one another and which each have a gripping end (111, 121) for gripping a workpiece (9). Each of the two gripper arms (11, 12) is coupled to a common guide head at the end (114) opposite the gripping end (111, 121) and to a separate link (13, 14) in a central region between the two ends. The two links (13, 14) are each rotatable about a fixed pivot (140). According to the invention, the fixed pivot (140) of the link (13, 14) of the one gripper arm (11, 12) is arranged closer to the other gripper arm (11, 12) than the fixed pivot (140) of the link (13, 14) of this other gripper arm (11, 12). As a result, the two gripper arms (11, 12) are swung outwards to a smaller extent when being swung apart.

Description

Technical field [0001] The invention relates to a workpiece conveying device for a forming machine according to the preamble of independent claim 1. Background technique [0002] In today's general forming machines, workpieces are usually placed in some forming stations by means of some workpiece conveying devices and / or taken out from these forming stations after forming. The multi-stage forming machine has a plurality of forming stations arranged in sequence, and a workpiece is processed in each forming station in sequence. In this case, the workpiece is transported between the various forming stations by means of a workpiece transport device. [0003] The known workpiece conveying device includes a plurality of clamps, which are used to simultaneously grasp, convey, and then release the workpieces in each forming station. For this purpose, a drive is used to jointly drive the clamps in the rhythm of the machine. [0004] There are various types of clamps in the prior art. For ...
