Explanation of the invention (9) Blade (11) and blank Rotation, swing and movement of the key blade (13). The specific arrangement shown in the figure makes ‘synchronous rotation, swing and movement by the transmission members (14), (15) and (16). The method for achieving synchronous axial movement is described below. In the specific arrangement shown in the figure, the 'tool head (21) is mounted on a movable carriage (24) connected to a cam carriage (19)'. The movable connection may be of any suitable type so that the two carriages (19) moves synchronously with (24) but in the opposite direction. As shown in the example, the transmission connection includes a rotatable gear (25) that meshes with two gear carriers (26) and (27). The gear carrier (26) is connected to or integrally formed with the trailer (19), and the gear carrier (27) is connected to or integrally formed with the trailer (24). Due to the aforementioned arrangement, turning the gear (25) causes the carriages (19) and (24) to move in opposite directions simultaneously. When the gear (2 5) rotates in one direction, the cam element (17) on the key blade (11) and the formed member (22) on the blank key blade (13) are simultaneously dragged. Any suitable reversible transmission (not shown) can be used to rotate the gear (25). k It can be understood that other types of devices cannot be required to move the carriages (19) and (24) in the opposite manner as described above. It is also understandable that the synchronous axial movement is somewhat different from the above special description. Special description of the modified device, the use of a separate forming tool instead of two 'The modified device can be controlled so that the forming tool handles blank blades to form two series of indexing surfaces and associated gradient surfaces (4) . The tool can be controlled to take turns forming a series of parts and then forming another series of parts. However, it is better to start another series after forming one series completely. 13 This paper size applies the national standard (CNS) A4 specification (210 X 297 public love) — — — — — — — — — — — — 111 — — — I 1111111 Please read the precautions on the back before (Fill in this page) 43 63 4 6 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention () 10 Figures 4 and 5 schematically illustrate another key copying device. The device includes a forming head (30) and a bracket assembly (31) which can be moved to the forming head (30). In the arrangement shown, the forming head (30) includes a guide pin (32) and a guillotine cutter (33) that rotates about a shaft (34). Both the guide pin (32) and the circular cutter (33) are mounted on the fixing element (35) in such a manner that their relationship does not change in the direction of the shaft (34). The bracket assembly (31) includes an arm (36) or other fixed equipment supporting two chucks (37) and (38) (Fig. 5), and is mounted on a bracket pivoted on a shaft (40) (39) on. The arranging bracket (39) can move the forming head (30) in the direction of the shaft (40). Both the chucks (37) and (38) can rotate on a general rotation axis (41) parallel to the axis (34). Any suitable transmission member (not shown in the drawing) operable to rotate the chucks (37) and (38), and any suitable member for synchronizing and correspondingly rotating the chucks (37) and (38) may be used. In this arrangement, there is no such transmission member and the chucks (37) and (38) can rotate freely, but the two chucks are connected to each other to cause synchronization and corresponding rotation. This interconnection and the interconnection of the aforementioned guide pin and the cutter (33) form individual parts of the synchronization member discussed previously. When the two elements are engaged, the key (1) moves the guide pin (32) longitudinally so that the key (1) interacts with the guide pin (32), thereby causing the chucks (37) and (38) to rotate accordingly. The collet (37) is modified so that it can grip the original key (1) in a releasable manner so that the longitudinal axis of the blade substantially coincides with the shaft (41). For the purpose of the following description, it will be assumed that the device is intended to reproduce the general kind of key (1) shown in Figure 1.
