Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of the tri-press device.

A try press machine is a machine that aligns press molds after they are completed and repairs defective parts of the press molds.

Figure 1 shows a conventionally used tripress device.

In Figure 1, a is the main body of the Tripress device, blt
Reference numeral b2 denotes an upper die correction section of the press die, which is provided outward from the three opposing end surfaces of the tri-press apparatus main body a.

C is an upper plate, and d is a guide column provided at the four corners to support the upper plate and to guide the ram e so as to be able to move up and down.

The ram e is raised and lowered by a drive mechanism (not shown).

f is the lower die of the press die, and is attached to the movable bolster g.

j is a rail that passes through the main body of the try press apparatus and extends further outside from the upper die correction section, and h is a lower die correction section of the press die.

In such a tri-press device, the ram is raised and lowered by a ram drive mechanism (not shown) of the main body a of the tri-press device, and an upper mold i is attached to the ram, and a lower mold f is mounted below.
A movable voltas g equipped with is placed and the try press work is performed by sandwiching the blank material.

After the erase operation, the upper mold i is released from the clamper (not shown) provided on the ram of the try press main body a,
The movable bolster g is moved along the rail j together with the lower die f of the movable bolster g and placed into the upper die correction section.

The ram e is lowered in the upper die correction section b1, and the upper die i is clamped on the ram e by a clamper device (not shown).

Furthermore, the ram e is raised and held at a predetermined height.

With the upper mold i in this state, the operator makes corrections to the portions that require correction.

After lifting the upper mold i, the lower mold f moves further from the upper mold correction part b1 to the lower mold correction part outside, and at the same time, the operator makes corrections to the parts of the lower mold f that need to be corrected.

While one press die is being corrected, a try press operation is simultaneously performed using the main body of the try press apparatus, and corrections are made using an upper die correction section and a lower die correction section provided on the other press die.

In such a try press machine, the modification of the upper mold i is as follows:
As shown in the figure, the work is upward for the worker, making it difficult to perform the work, poor workability, and requiring a long time for mold correction.In addition, polishing dust is visible to the worker's eyes as the mold surface is polished during the mold correction work. This is causing the work environment to deteriorate.

This invention was developed in view of the above points, and it can significantly improve work efficiency by eliminating upward work in the upper mold correction section, and also improve the working environment by preventing polishing powder from falling onto workers. The present invention aims to provide a tri-press device that can achieve the following.

The configuration will be explained below based on the embodiment shown in FIG. 2 and below.

In the figure, reference numeral 1 indicates the upper mold correction portions provided on both sides of the tripress device.

The base 2 is installed on the foundation, and the slides 3, 3 on both sides
Guide a.

Liners 4, 4a are attached to the slides 3, 3a on both sides, and the base 2 is provided with a guide surface 5 and a gib 6 on which these slides come into sliding contact.

The gib 6 slides 3° 3a relative to the moving bolster by adjusting push bolts and pull bolts (not shown).
The parallelism of the slides 8 and 8a and the right angle of the vertical movement of the slides 8 and 8a are maintained accurately.

T is a reversing plate located between the two slides 3 and 3a,
One shaft 8 of the shafts 8 and 8a provided coaxially on both sides of the reversing plate 1 is supported by a bracket 9 provided on one slide 3, and the other shaft 8a is supported by a worm reducer provided on the other slide 3a. It is connected to the worm wheel shaft of the machine 10.

A worm shaft of this worm reducer 10 is connected to a reducer and a motor 11 with a brake via a coupling 12.

Bosses 18 and 18a coaxial with the shafts 8 and 8a are protruded from the outer circumferential side of the reversing plate T.
8t18a is connected by a link 14 to levers 15 located on both sides of the base 20 and connected by a shaft and rotated at the same time, so that both bosses 18, 18a move up and down at the same level.

16 is a support for the lever 15. Reference numeral 1γ denotes a hydraulic cylinder for raising and lowering the slide, which is fixed to the base 2. The slides 8 and 8a move up and down as the cylinder 1γ expands and contracts, and the lower surface 18 of the slides 3 and 3a comes into contact with the upper surface 19 of the base 2. This contact serves as the lower limit of the stroke of the slides 3, 3a.

This reversing plate 7 is located on one side of the lower surface of the reversing plate γ, and on one side of two locations facing each other across the rotational axis of the reversing plate 1.
A stopper stand 20 is fixedly provided to which a stopper 21 is fixed, which comes into contact with the upper surface of one of the slides 3 when the slide 3 is not inverted.

Further, a plate 24 is fixedly provided at the bottom of the reversing plate 1 on the opposite side of the rotation center from the stopper 21, and a wedge 23 is provided on the upper surface of the slide 3 opposite to this plate 24.

This wedge 23 is movable in and out, and by protruding, it engages with the plate 24 and the plate 24
It is designed to push up and energize.

When this plate 24 is pushed up, this plate 2
A stopper 21 located on the opposite side of the rotation center of the reversing plate 1 with respect to 4 is in close contact with the upper surface of the slide 3 so that the reversing plate 1 maintains parallelism with respect to the movable bolster.

25 is an adapter plate, and 26 is an upper die, which are fixed to the lower surface of the reversing plate 1 by a clamper 27.

28 is a guide for the wedge 23, 29 is an air cylinder for moving the wedge 23 in and out, and 30 is a rail for moving the bolster.

In the above configuration, after moving the movable bolster to which the upper and lower molds are attached from the main body of the Tripress device into the upper correction section 1, the stopper 21. While the reversing plate 1 is held parallel to the moving bolster by the plate 24, guide surface 5, and gib 6, the slides 3 and 3a are lowered by the hydraulic cylinder 1γ, and the reversing plate 1 is moved to the adapter plate 25 or the upper die 26.
The adapter plate 25 or the upper mold 26 is fixed to the lower frame of the reversing plate 1 by operating the clamper 2T.

Next, operate the hydraulic cylinder 1γ to move the slides 3 and 3a.
At the same time, the reversing plate γ is raised, and the movable bolster on which the lower mold is placed is moved to the lower mold correction section.

The reversing plate 1 raised within the upper mold correction section 1 is moved to the wedge 23
By retracting the blade and disengaging it from the blade 24, it becomes possible to reverse it around the shafts 8 and 8a. In this state, the motor 11 rotates the reversing plate 7, and the mold surface of the upper mold fixed to it is rotated. Orient it in a direction that will make it easier to make corrections.

Then, the motor 11 is stopped at that position, and the attached brake is used to fix the motor 11 to correct the upper mold.

In FIG. 2, the inverted state is shown by a solid line, and the non-inverted state is shown by a virtual line.

After correcting the upper mold in this way, in order to stack it on the lower mold, the motor 11 rotates the reversing plate 7, and the stopper 2
1 is brought into contact with the upper surface 22 of the slide 3, and then the wedge 23 pushes up the plate 24 to fix the reversing plate 7 to the slide 3.

Place the upper mold on the lower mold by reversing the procedure described above.

Although the above embodiment is a case of a single-acting tri-press device, the same applies to a double-acting tri-press device.

FIG. 5 shows an embodiment of a double-acting tri-press device, in which 25' is an inner adapter plate, 25a' is an outer adapter plate, 26' is an inner upper die, and 26a is an outer adapter plate.
' is an outer upper mold, 27 is an inner clamper, and 27a' is an outer clamper.

When attaching the upper and lower molds to the movable bolster from the main body of the try press apparatus, the difference in height between the upper surface of the inner adapter 25' and the upper surface of the outer adapter 25a' is kept approximately constant.

In the embodiment shown in FIG. 5, an inner adapter 25' and an outer adapter 25. (Block 31' is placed in between.

Even when the inner upper mold 26ζ outer upper mold 261 is directly clamped, the difference in height between the upper surface of the inner upper mold 6' and the upper surface of the outer upper mold 6a' is kept almost constant using a method similar to the embodiment.

The present invention is as described above, and an upper die correction section 1 is provided on the side part of the main body of the try press apparatus to correct the upper die by taking out the movable bolster on which the upper die and the lower die are stacked from the main body.

A link 14 connects both ends of the pivot portion and levers 15 located on both sides of the base 20 and connected by a shaft and rotating at the same time.
and on the lower surface of the reversing plate 2, and this reversing plate 7
A stopper 21 that contacts the top surface of the slide 3 is fixed to one side of the two opposing locations across the axis of rotation, and a plate 24 is fixed to the other side. Since the tri-press device is constructed by providing the wedge 23 that can be freely retracted and retracted to engage the plate 24 in contact with the plate 24, the reversing plate 7 to which the upper die is fixed
can be rotated and moved up and down to an easy-to-work position, which eliminates upward work in the upper die correction section, significantly improving work efficiency, and also prevents polishing powder from falling onto workers during mold correction work. This will improve your work environment.

In addition, the reversing plate 7 can move up and down at the same level, and is fixed with the upper mold facing downward, so that the posture of the upper mold when moving up and down can be fixed in the correct state.
The upper mold can be accurately raised or lowered with respect to the lower mold on the bolster, and in particular both molds after correction can be accurately overlapped without damaging them.
