However, in the transfer press shown in FIG. 1, the workability and visibility are poor due to the presence of the upright d between each step, and it is necessary to provide an idle station for each upright d. In addition to the large size of the press, it is difficult to set up, and the position of the work shifts at the idle station, which lowers productivity. Further, in the transfer press shown in FIGS. 2 and 3, it is necessary to change the dividing method every time the press specification changes, so that a large number of man-hours are required for design and assembly, which leads to an increase in cost, There are problems such as difficulty in standardization. In addition, in the transfer press shown in FIGS. 4 and 5, the placement of the press points and the mounting tie bolts restricts the installation space of the sub-slide, so there are many difficulties in designing and manufacturing, and a new sub-slide is added. Therefore, there is a problem that the structure is complicated and power is wasted because the weight of the movable portion increases. Moreover, any transformer
The key press also has a slide guide that guides the slide up and down.
Since the guide is laid on the upright side,
If the slide is divided for each station,
Each application has an upright and slides into these uprights
Because of the need to provide a guide,
As the number increases, workability and visibility deteriorate,
If an idle station is provided for each
