Description

[Detailed Description of the Invention] The present invention relates to a novel improvement proposal for a work table for a forging press machine.

It is known that the work table of a forging press machine can be rotated, but in Utility Model Publication No. 54-16896, various rotation means are installed on the underside of the table, which increases the height of the table and reduces the impact on the table. As a result, various troubles occur frequently and there are problems with workability.

Further, in Japanese Utility Model Publication No. 54-16895, it is made to rotate via an air cylinder and a link mechanism, but there is a problem in workability because there is a limit to the stroke of the cylinder.

This invention has been developed in consideration of the above points,
The present invention will be explained below based on the drawings.

1 is a lower stand, and a circular hole 2 is bored in the center of the lower stand 1.

3 is a circular table base with a shaft 4 in the center of the back side.
-e, and fit into the circular hole 2 via the washer plate 5.

In this case, the table base 3 is made of steel and has a relatively thick wall (approximately 150 to 160 mm) like the conventional press base.

On the other hand, a concave notch ring 6 facing inward of the table is bored in the outer peripheral end side edge A of the table base 3, and is positioned equidistantly from the top edge of the table with respect to the empty chamber opening of the notch ring 6. A large number of pins 7 are made to stand up.

On the other hand, the cutout ring 6 of the table 3 is placed at one place on the lower table 1.
A bearing plate 9 rotatably supports a chain ring 8 for meshing with a pin 7 provided therein, and 10 is a support shaft on the bearing plate 9.

At this time, a small-diameter chain ring 11 is integrally provided at the bottom of the chain ring 8 through a sleeve 12 without contacting the table base 3, and the chain ring 11 is rotated by the drive of a motor. This causes the chain ring 8 to rotate, which engages the pin 7 and rotates the table base 3.

Reference numeral 13 denotes a drive box provided adjacent to the bearing plate 9, and a drive motor 14 and a speed reducer 15 are mounted on the top of the box.
is provided, and the reducer shaft 16 is provided inside the case.
Another chain ring 17 is provided at the end, and a chain 718 is installed between it and the chain ring 11 on the bearing plate 9.

The present invention is constructed as described above, and when the motor 14 is now driven, its rotation is decelerated through the reducer 15, and the rotation is reduced through the chain ring 17, the chain ring 718, the chain ring 11, and the chain ring 8. This allows the table base 3 to rotate slowly.

The rotation is performed by operating a switch on an operation panel (not shown).

In the present invention, since the rotating means is not housed below the table base 3, the height of the table is not increased, and the rotating means does not receive direct impact during forging.

With this invention, the height of the table base can be adjusted freely without any restrictions, and since the impact received during forging does not directly affect the rotating chain ring, there are no operational problems and the overall This allows for a simplified configuration.

In addition, the concave notch ring on the outer peripheral edge of the table base of the present invention is easy to drill, and it is also easy to install a bottle from above. Together, they can be manufactured at low cost, and since the pin is engaged with the chain ring and rotated by the drive of a motor, the required rotation can be obtained quickly and accurately, which improves work performance. It is excellent.
