Description

[Detailed Description of the Invention] The present invention relates to a central idle finger external setup change device for a three-post three-dimensional transfer press.

In three-post transfer presses, central idle finger replacement has traditionally been done internally.

The purpose of this invention is to create a three-column three-dimensional transfer shaft that allows the fingers of the central idle to be replaced by external setup, and that prevents the finger arm from lifting up to ensure reliable workpiece transfer. An object of the present invention is to provide a central idle finger external setup change device for a press.

Hereinafter, the present invention will be explained with reference to the drawings.

In the figure, A is the main body of a three-post transfer press, which has two moving bolsters 22 and 23.
A pair of transfer bars 25 are provided above the product along the transport direction (arrow) of the product. These transfer bars 25 are connected to each moving bolster 2.
2, 23 and upright 21a, and the movable side transfer bar 3 above each moving bolster 22, 23 is connected to the moving bolster 2.
When drawing out 2 and 23, the moving bolster 22,
It is designed so that it can be pulled out of the press A together with 23. Furthermore, an idle station is provided between each moving bolster 22 and 23, and a fixed transfer bar 1 is connected to this idle station.
is placed.

A moving guide 4 is fixed to the upper surface of the movable transfer bar 3 along the axial direction, and a plate 5 is movably provided between these moving guides 4.

A moving cylinder 6 is attached to the movable side transfer bar 3.
The rod 7 of the moving cylinder 6 is connected to the bracket 8 of the plate 5 by a pin 9.

In the drawing, reference numeral 11 denotes a finger arm, and the base of this finger arm 11 is attached to a bearing body 14 fixed to the plate 5 by a pin 15 so as to be movable up and down. A finger attachment member 12 is fixed to the tip of the finger arm 11, and a finger is attached to the finger attachment member 12. These fingers are used to carry workpieces into and out of the idle station.

A pin hole 1 is provided at the base end of the finger arm 11.
3 is formed, and the base of an undulating cylinder 17 is connected to the bracket 16 of the plate 5 by a pin 18, and the rod 19 of the undulating cylinder 17 is provided with a pin 20, and the pin 20 is connected to the pin hole 13. It is inserted inside.

On the upper surface of the fixed transfer bar 1, a moving guide 10 for the finger arm 11 and a lifting prevention member 1a are fixedly provided.

The end portion 11a of the finger arm 11 is inserted into the anti-lifting member 1a.

Next, the operation will be explained. When replacing the mold, the moving cylinder 6 is operated to move the plate 5 in the Y direction to pull out the end 11a of the finger arm 11 from the lifting prevention member 1a, and the undulating cylinder 17 is extended to move the finger arm 11 to the pin 15, that is, the fulcrum. Rotate around P and stand vertically. In this state, the moving bolster 23 is moved in the Z direction to carry the mold out of the press A. At this time, since the finger arm 11 is in an upright state, it comes out of the press without interfering with the central apply 21a.

Then, the fingers are replaced by external setup.

The moving bolster 23 is inserted into the press A, and after replacing the mold, the undulation cylinder 17 is contracted to bring down the finger arm 11, and the moving cylinder 6 is activated to move the plate 5 in the X direction, and the end of the finger arm 11 is moved. The part 11a is lifted up prevention member 1a
Insert into.

As described in detail above, the present invention includes two moving bolsters 22, 23, each moving bolster 22, 23, and each upright 21 of the press body A.
In a three-post transfer press having a plurality of transfer bars 25 divided into a plurality of sections, a fixed transfer bar is attached to a movable transfer bar 3 connected to a fixed transfer bar 1 located at an idle station between each moving bolster 22, 23. A movable plate 5 is provided on the first side, and a moving cylinder 6 for moving the plate 5 is provided on the movable transfer bar 3.
A finger arm 11 whose tip end 11a protrudes toward the fixed transfer bar 1 side and holds the finger is provided so as to be able to be raised and lowered, and the plate 5 is provided with a lifting cylinder 17 for raising and lowering the finger arm 11. The present invention is characterized in that a lifting prevention member 1a is provided into which the tip end 11a of the finger arm 11 is inserted when the finger arm 5 moves toward the fixed transfer bar 1 side. Therefore, when replacing the mold, the moving cylinder 6 is operated to pull the plate 5 and remove the tip 11a of the finger arm 11 from the lifting prevention member 1a.
The finger arm 11 is activated by operating the undulating cylinder 17.
Since interference of the finger arm 11 with the central upright when moving the moving bolster out of the press can be eliminated, the fingers of the idle station can be replaced by external setup.

Moreover, the finger arm 1 is
1, the finger arm 11 on which the finger is attached may be damaged due to vibration etc. when transporting the workpiece.
However, when the plate 5 is moved toward the fixed transfer bar 1, the tip 11a of the finger arm 11 is inserted into the lifting prevention member 1a, so lifting of the finger arm 11 is prevented. Therefore, the workpiece can be transported reliably.
