Description

[Detailed Description of the Invention] The present invention relates to an improvement of a die lifting device such as a die setter of a tri-press device.

As shown in FIG. 1, the die setter in the upper die correction section of the Tri-Press machine has a die slide 1 with a die clamper 2 that engages with a notch in an adapter plate 3 and tightens the adapter plate 3. The upper mold 5, which has been placed on the mold 4, is suspended.

When correcting the upper mold, the die slide 1 is reversed or tilted around the rotation axis 6 to facilitate the correction work.

Note that 7 is a key. However, when the die slide 1 is rotated in the direction of the arrow, a downward sliding force of the adapter plate 3 acts, so some kind of ingenuity is required.

One idea would be to insert a key between the die slide 1 and the adapter plate 3, but this would take a lot of time and there is a concern that an accident may occur if the key is forgotten.

The purpose of the present invention is to focus on the above points and provide an adapter plate slip prevention device that can shorten working time and prevent danger. A non-slip pin is provided on the die slide opposite to the side surface of the adapter plate on the side to which the adapter plate is attached, and is biased by a fluid pressure cylinder to come into contact with the side surface of the adapter plate to prevent the adapter plate from slipping. be.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a sectional view showing one embodiment of the device according to the present invention, and FIG. 3 is a front view thereof.

In the figure, 1 is a die slide, 1a is a bracket provided on the side surface of the die slide, and 3 is an adapter plate.

Reference numeral 11 designates a non-slip pin, which has a screw threadedly engaged with the lower end of the bracket 1a on its curved surface, and passes through the lower end of the bracket 1a so that its end face faces the side surface of the adapter plate 3.A pinion 12 is attached to the main body via a key. It is fitted.

Reference numeral 13 denotes an air cylinder that engages with a rack 14, and the rack 14 meshes with the pinion 12.

15 is a rack pressing roller.

16 is a rod, which is inserted into the pin 11 and has a spring 16b at one end.
The pin 11 is made to protrude slightly from the end face thereof, and the other end of the holder which is interlocked with the pin 11 is connected to a limit switch 17 on the stand 16a.

When the pin 11 comes into contact with the adapter plate 3, the rod 16 comes into contact first, so a relative movement occurs between the pin 11 and the rod 16 due to the amount of protrusion. is activated.

The operation in the case of the above configuration will be described.

When rotating the die slide 1, the air cylinder 13 is first activated to rotate the pinion 12 via the rack 14.

Since the pin 11 rotates together with the pinion 12 and is screwed into the bracket 1a, it moves in the axial direction and comes into contact with the side surface of the adapter plate 3 to support the adapter plate 3.

At the same time, the □ seat switch 11 is activated to stop the operation of the air cylinder 13 and to make the motor for rotating the die slide 1 operable.

The present invention as described above has the following effects.

When the guide slide 10 rotates, the pin 11 is brought into contact with the side surface of the adapter plate 3 in advance to support it, so that the adapter plate 3 can be prevented from slipping off and the working time can be shortened.

Furthermore, since the operation of the pin 11 and the drive of the rotating motor of the die slide 1 are interlocked by the limit switch 17, danger is reliably prevented.
