Embodiment Construction

[0040] figure 1 A very schematic illustration of a transport device 20 is shown for transporting round blanks or for transporting round blank parts 21 to stamping stations 22 . The transport device 20 may comprise one or more carousel feed plates 23, each carousel feed plate comprising a plurality of notches 24 on its circumferential area. When a particular turntable feed plate is rotated about its turntable axis, a round blank comprising a plurality of round blank portions 21 or at least one of the round blank portions 21 may be present in the recess 24 and transported.

[0041] In an exemplary embodiment, a multi-piece circular blank is provided from which a coin 27 is stamped in a stamping station 22 ( Figure 7 with Figure 8 ). In the exemplary embodiment, coin 27 or circular blank includes three distinct circular blank portions 21 : circular blank core 28 , outer ring 29 , and circular blank ring 30 . A circular blank ring 30 is arranged between the circular blank co...

Abstract

The invention relates to a method and an insertion device for inserting a circular blank ring into an outer ring. For this purpose, the outer ring is first transported to the insertion point (E) in the feed device. Simultaneously, the circular blank ring is brought into the starting position (P) in the feed device. The circular blank ring is first aligned coaxially with respect to the axis (A) by means of a centering body arranged coaxially with respect to the axis. The circular blank ring only moves radially relative to the axis (A). Then, the circular blank ring is inserted into the hole of the outer ring by means of a push block. During this movement of the circular blank ring from its starting position (P) into the outer ring, the circular blank ring is coaxially aligned relative to the axis (A) by means of a centering mechanism, preferably by means of a centering channel. The circular blank ring performs a superimposed movement in the axial direction (V) as well as in a radial direction radial to the axis (A).

Description

technical field [0001] The invention relates to a method and an insertion device for inserting a circular blank ring into an outer ring of a circular blank. Background technique [0002] A round blank comprising a plurality of round blank parts is known from DE 10 2010 013148 A1. The circular blank includes a circular blank core, an outer ring and a circular blank ring disposed between the circular blank core and the outer ring. The circular blank core and outer ring are made of metal material. The circular blank ring is essentially made of a plastic material, for example a polymer. [0003] When a circular blank ring made of plastic material is joined to another circular blank part made of metal, the circular blank ring may be deformed and damaged. After the center hole has been punched out, the outer ring has burrs. It is not known on which side of the outer ring the burr is located during bonding. In particular, such burrs may damage circular blank rings made of soft...
