となるのである。(Function) The metal plate 1 is moved up and down by the ram 15 as described above.
The metal plate 1 is intermittently transferred by a certain length each time, and four window holes 9a, 9b, 9 are formed on the metal plate 1.
c, 9d and four ribs 12a, 12b, 12c,
12d, the ram 5 is driven up and down seven times in total. That is, the metal plate 1 passes through the following seven stages to become a handrail body having a window hole with a beaded edge.
金属板1の前端部だけが挿入された第1段階で

9aが穿設される。 In the first stage, in which only the front end of the metal plate 1 is inserted, only the punching of the first window hole 9a is required, and three steps are performed: forming the raised part, forming the bead, and punching out the ribs. Since different types of press working are not required, the press upper molds 2b, 2c,
2d does not require any pressing operation. Therefore, the operation blocks 7b and 7 corresponding to these press upper molds are
c, 7d are the block drive devices 8b,
It is moved back and forth by the operations of 8c and 8d, and when the ram 5 moves downward, it descends between adjacent press upper molds and performs blank firing. That is, only the upper press mold 2a for punching the window hole moves downward, and the other press upper molds 2b, 2c, and 2d do not move downward. Thus, the first window hole 9a is bored as shown in FIGS. 5 and 6.

c・2dは下動しない。 In the second step, in which the metal plate 1 is further inserted for a predetermined length, as shown in FIG. Since only the punching of the window hole 9b is required, the operation block 7c for forming the bead and the operation block 7 for punching out the ribs are operated in the same manner as described above.
When the ram 5 is moved back and forth and the ram 5 is moved downward, blank firing occurs in the same manner as described above. In this way, only the press upper die 2a for window hole punching and the press upper die 2b for start-up work move downward, and the other press upper die 2 move downward.
c.2d does not move downward.

aの形成がなされる。 Similarly, in the third stage, only the upper press die 2a for punching the window hole, the upper press die 2b for raising the punch, and the upper press die 2c for forming the bead are moved downward; Therefore, as shown in Figure 8, 3
Punching the second window hole 9c, raising the peripheral edge of the second window hole 9b, and punching the bead 11 to the first window hole 9a.
A is formed.

リブ12bの打出しがなされる。 In the fifth stage, the upper press die 2a for punching the window hole does not move downward and the press die 2b performs the rising process, the upper press die 2c for forming the bead, and the upper press die 2d for punching out the ribs. The chisel moves downward to raise the peripheral edge of the fourth window hole 9d and form a beaded edge 11c in the third window hole 9c, as shown in FIG.
A second rib 12b is punched out between the second and third window holes 9b and 9c.

Only the upper die 2d moves downward, forming the beaded edge 11d in the fourth window hole 9d and forming the bead edge 11d in the third and fourth window holes 9c, 9 as shown in FIG.
The third rib 12c is punched out between the parts b.

and press lower die 3c are sequentially installed in parallel, and a block support frame 6 is attached to the push-down ram 5 of a single press 4.
The block support frame 6 is equipped with operation blocks 7a, 7b, . ...metal plate 1
It is further equipped with block drive devices 8a, 8b, etc., which move the ram 5 back and forth individually along the transfer direction, and when the ram 5 is moved up and down multiple times to perform press processing on the metal plate 1, unnecessary presses are removed at that time. A controller 20 for setting the operation order of the block drive device is provided, which has a circuit configuration such that the operation block corresponding to the upper die is moved downward into the side space of the unnecessary press upper die, and each block drive device 8a, 8b is ... to the controller 20
Since the operation is controlled by electrical signals from the press die, there is no need to attach and detach the press die each time the type of press work to be performed on the metal plate 1 changes. Therefore, the labor burden required for attaching and detaching the press molds is completely eliminated, and it is possible to improve the overall working efficiency of press working.

The lower press mold 3a, the upper press mold 2b and lower press mold 3b for raising the window hole peripheral edge, and the upper press mold 2c and lower press mold 3c for forming the beaded edge are:
Since they are installed in parallel at the same interval equal to the transfer length of the metal plate 1 at one time, as mentioned above, the operation blocks corresponding to the press upper molds that are not needed at that time can be moved to the unnecessary press upper molds. By simply moving the ram 5 up and down several times and intermittently transporting the metal plate 1 while blankly lowering it into the side space, the process from punching the window hole to raising the peripheral edge of the window hole, etc. A series of steps up to the formation of a beaded edge for rounding the raised periphery are sequentially executed for each window hole, and at the stage when the metal plate 1 has passed through the processing equipment, a plurality of windows with beaded edges are formed. A metal plate product with holes formed at predetermined intervals is completed.

There is no need to set up the periphery of the rim or to install a separate press processing device to circularly bend the erected periphery to form the bead. There is no increase in the floor space occupied by the building.
