Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mold changing device having four punch presses in which a plurality of mold changing devices are provided on a handling base and the handling base is movable.

Conventionally, mold changing devices for punch press machines equipped with stripper-type molds still exist, and tool changing devices used in processing machines such as machine tools Since there is no tool to process two pieces in a set, the handling for replacement is one piece type. Therefore, when this was used in a punch press machine, there was a drawback that it took a long time to replace the mold.

In addition, the tool handling of current machine tools such as machining centers is all installed inside the machine.
Since its operation is rotational, the space for storing tools is limited, and the number of tools that can be stored is therefore severely limited.

Furthermore, although many punch press machines are currently operated manually, the trend towards automation is rapidly gaining momentum. However, since a punch press machine has a pair of tools and uses a much larger number of tools than other processing machines, it is not applicable to the tool changing device of a cutting machine. Therefore, there is a need for a system in which a mold changing system is provided outside the punch press machine body, and a mold changing function can be added to the number of punch presses as needed.

This invention has been made in view of the above points, and provides a punch press machine in which the exchange of the upper and lower molds of the punch press machine is automated, and the lower mold exchange device is made movable and resistant. be. This invention will be explained below.

Next, the operation will be explained.

To perform processing with the punch press machine having the above configuration, the upper substrate 6 and the lower layer &9 are rotated, and the upper mold 1 and lower mold 10 necessary for processing are withdrawn and fixed under the hammer 3. Then, the workpiece W held in a cantilevered state by the workpiece holding device 21.21 is moved by the X-axis chinor 15 and the Y-axis chifurle 19, and the one direction where the workpiece W is to be processed is aligned with the upper mold 7. Position the lower mold 10. Work W
When the is positioned, the press s2 operates and the
is lowered and the head 8 of the upper mold 10 is struck to punch a hole in the workpiece W.

Next, in order to exchange the upper mold 1 and the lower mold 10 with the upper and lower mold exchange device, the no-end ring base 31 is moved for 1" and stopped at a predetermined position shown in FIG. let

Next, install the vertical 1M7-mm 35.39 for the upper and lower molds in Figure 2 (b).
) move up and down in the direction of the arrows to move the horizontal arm 3 for the upper and lower dies.
At step 2.36, the upper and lower molds 7 and 10 are stopped at a position where they can be gripped. Next, the upper and lower mold drive devices 33, 3? to move the upper and lower mold horizontal arms 32 and 36 in the direction of arrow E in Fig. 2.
, F all the way forward, and the upper and lower mold grips 34.
38, grasp the upper mold lifting fitting 25 and the lower mold 1u, raise the vertical arm 35.39 for the upper and lower molds a little, pull out the upper and lower pot molds 1.10 from the upper and lower substrates 6, 9, and Move the F-type horizontal arm 32, 36 backward (arrow E, F direction and anti-mowing direction).

Meanwhile, the handling base 31 runs on the rail 41 and returns the upper and lower molds 7, 10 to the mold storage shelf 42 for storage. Next, the required upper and lower molds 7 and 10 are grasped, and the upper and lower molds are moved again on the handling base 31 and stopped at the upper and lower mold mounting positions. Next, horizontal arms 3 for upper and lower dies
2. Move forward 36, open the upper and lower mold grips 34.38, and attach the upper and lower molds 1 and 10 to the upper and lower substrates 6 and 9, and then return the handling base 31 to its original position. .

As explained above, the present invention provides a punch press with a handle base having a lateral pressure, and a top die having an upper die on one side, and a lower die on the other side of the handling base. The punch press 1 is equipped with a lower mold exchange device for exchanging the punch press 1 and a rail for running the handling base.
The upper and lower molds can be molded at the same time. For this reason, the travel distance and time are reduced to less than 1/2 compared to the case where one die changing device is used for changing layers. In addition, even if the number of molds in the punch press machine increases, many mold storage shelves can be installed, which has the advantage of improving workability and reducing main seat costs.
