Description

[Detailed description of the invention] A. Industrial application field The present invention relates to a punching press, and more specifically, the invention is capable of discharging products and slugs of all sizes by providing a swinging mechanism on a table divided into multiple parts. This relates to a punching press that can.

B. Technical background of the invention and its problems Conventionally, when blanking is performed in a turret punch press, for example, the punched product or slug is dropped below the die through a hole in the die. However, recently, large products that cannot be machined with a single mold are sometimes blanked or large holes are machined by nibbling or punching.

In such cases, large blanks (products)
However, conventional punching presses have a chute for taking out products or slug, as shown in, for example, Japanese Utility Model Application Publication No. 182497/1983.
It is about 200 mm square and cannot be used, so
The machine had to be stopped temporarily and removed manually.

Therefore, when processing is controlled by a numerical control device, even though it is automated,
Currently, there is a problem that workers must monitor.

C. Purpose of the invention This invention was created in view of the problems mentioned above.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a punching press capable of discharging products and slugs of all sizes by providing a swinging mechanism on a table divided into a plurality of parts.

D. Means for solving the problem In order to achieve the above-mentioned purpose, this invention has a guide bar that is movable toward and away from the punching position, and a guide bar that is movable in the direction of movement of the guide bar. A punching press is provided with a work holding device movable in orthogonal directions, and a fixed table is provided between a front side table and a rear side table that are integrally provided on both sides of the guide bar. The fixed table is divided into a plurality of tables in the direction of movement of the guide bar, and one end of the front side table or the rear side table of each table is provided so as to be tiltable downward.

E. Embodiment Hereinafter, an embodiment of the present invention will be specifically described with reference to the drawings.

FIG. 3 schematically shows a turret punch press as a punching press, in which an upper frame 3 is integrally provided above the base 1.

A disk-shaped lower turret 5 and an upper turret 7 are rotatably mounted on the base 1 and the upper frame 3, respectively. The upper turret 7 and the lower turret 5 rotate synchronously in the same direction, and the lower turret 5 has a plurality of dies 9 arranged and mounted on a concentric circle. Further, the upper turret 7 is equipped with a plurality of punches 11 corresponding to the dies 9. A striker 13 for striking the punch 11 is mounted at a fixed position on the upper frame 3 so as to be movable up and down.

A workpiece moving and positioning device is mounted on the base 1 to move and position the workpiece W in the front, back, left and right directions with respect to the punching position of the punch 11 and the die 9, which are pressed by the striker 13. That is, guide bars 15 (one side guide bar is shown in FIG. 3) are attached to both sides of the base 1, and extend in the left-right direction in FIG. A sliding body 17 is supported in a slidable manner. The sliding bodies 17 on both sides support the second guide bar 19 near both ends thereof. This guide bar 19 is connected to the base 1
It extends in a direction perpendicular to the guide bar 15 beyond the upper surface of the fixed table 21 attached to the upper part of the guide bar 15, and as described above, the vicinity of both ends thereof are supported by the sliding bodies 17 on both sides. The second guide bar 19 movably supports a work holding device 23 that holds one side edge of the work W.

In the turret punch press having the above configuration, the workpiece W is placed on the fixed table 21, and one side edge of the workpiece W is held by the workpiece holding device 23.
Clamp and fix. Next, the sliding body 17 is appropriately slid along the guide bar 15, and the work holding device 23 is moved along the second guide bar 19 to position the work W in the front, rear, left, and right directions. Punching is performed by applying pressure to the punch 11 with a striker 13.

As mentioned above, in order to receive and discharge the product or slug separated from the workpiece W, the discharge device 25, which is equipped with a swinging mechanism on a table divided into a plurality of parts, is installed at a position close to the punching position where punching is performed. There is.

The above is the general configuration of the punching press, and the ejection device 25 equipped with the swing mechanism according to the present invention
will be specifically explained with reference to FIGS. 1 and 2.

The ejecting device 25 is composed of tables 27A and 27B obtained by dividing the fixed table 21 into a plurality of parts, a swinging mechanism 29 that allows the tables to swing freely, and an actuating device 31 that swings the table.

In this embodiment, the tables 27A and 27B are, as understood from the illustrations in FIGS. 1 and 2,
The guide bar 19 is divided into two parts in the moving direction, and a plurality of ball bearings 33 that roll in the free direction are arranged on the upper surfaces of the tables 27A and 27B, and a front side table 35 (on the right side in FIG. 1) and a rear side table 37 (on the left side in FIG. 1), and a plurality of hinge parts 39 are provided on the lower surface of the rear end to allow for free swinging.
In addition, at the bottom of the front side table 35,
A space 41 is provided within a range that does not impede the ejection of the works W on the tables 27A and 27B.

The swinging mechanism 29 includes a bearing 47 on the top of a bracket 45 erected on the bed 43 and a table 27.
Hinge part 39 provided on the lower surface of the rear side of A, 27B
and the bearing 47 are coupled and pivotally supported by a pin 49 so as to be rotatable.

The actuating device 31 is a bearing 5 provided on the bed 43.
A connector 59 is fixed to the tip of a rod 57 of the cylinder 55 by a cylinder 55 (hydraulic or pneumatic) supported by a pin 53 on the cylinder 55 and swingable.
and the bearings 61 provided on the lower surfaces of the tables 27A, 27B are connected by pins 63.
A and 27B are swingable.

With the above configuration, the functions of the tables 27A and 27B are as follows: Due to the expansion and contraction of the cylinder 55, the tables 27A and 27B are moved from the horizontal position, that is, the position where the products and slugs are supported, to the hinge portions of the tables 27A and 27B.
With 9 as a pivot point, the table is tilted to the position indicated by the chain line X, and the product or slug on the table can be discharged to the front side.

F. Effects of the invention As can be understood from the explanation of the examples above, the gist of the invention is as stated in the claims for utility model registration, and as is clear from the description, the invention , a fixed table in a punching press is divided into a plurality of parts in the direction of movement of the guide bar 19, and one end of each of the divided tables 27A, 27B is provided so as to be freely tiltable downward. .

Therefore, according to the present invention, when the product to be separated from the plate material is relatively small, the product can be discharged by tilting only the table 27A located closest to the punching position. If the product is relatively large, the product can be discharged by tilting both tables 27A and 27B according to the size of the product.

That is, according to the present invention, the fixed table is divided into a plurality of tables 27A, 27B, and each table 27A, 27B is provided so as to be tiltable.
Table 27 that should be tilted depending on the size of the product etc.
A, 27B can be selected, and it can be easily handled regardless of the size of the product.
