Description

[Detailed description of the invention] This invention relates to the shape of a change rail used for changing molds in presses, forging machines, etc.

As a conventional guide change rail, there is one shown in FIG. 1, for example.

That is, in the shape of the conventional guide rail 1, (1) the guide rail portion 4 on which the pressing die 3 fixed on the beam 2 slides has a horizontal straight shape or a slightly inclined shape.

In addition, part of the base structure on which this guide change rail 1 is installed is the I-beam 7 built in the bit 6 and the floor support attached to the press machine 5 due to the bit structure unique to the press machine 5. It straddles the concrete structure of a wooden floor board 9 and a general floor surface 10 supported by brackets 8 and .

For this reason, when the weight of the impression mold 3 is applied on the guide change rail 1, there is a difference in the amount of sinking between the general floor surface 10 section and the wooden floor board 9 section, and work is required to adjust this level difference.

To adjust the level difference, insert a liner between the guide rail 1 and the wooden floorboard 9 when the guide rail section 4 has a horizontal straight shape, or as shown in the figure when the waist guide rail section 4 has an inclined shape. To carry the pressure mold 3 onto the bolster 11, use the step 12 as shown in the figure, and when pulling out the pressure mold 3, move the guide change rail 1 to 180.
This can be achieved by rotating the bolt 11° and using the other end which is lower in height than the upper surface of the bolster 11.

As described above, the conventional method has the problem that the work of adjusting the level difference occurs during the changeover work, and the work of resetting the changeover rail 1 occurs.

This invention was made by paying attention to such conventional problems, and aims to solve the above problems by devising the shape of the rail of the guide change.

This invention will be explained below based on the drawings.

FIG. 2 is a diagram showing an embodiment of this invention.

First, the configuration will be described. Reference numeral 15 is a floor surface of a concrete structure, and a bit 16 is formed on this floor surface 15.

A press machine 18 is installed within the bit 16 at a predetermined distance from the wall surface 17, and a beam 18 is bridged near the upper end of the wall surface 17.

A support bracket 20 is also attached to the press machine 18, and the beam 19 and the support bracket 20 are connected to each other.
A wooden floorboard 21 is placed between the two.

A guide change rail 22 is placed on the floor surface 15 and the floor board 21 mentioned above, and this guide change rail 22
A pin 24 that is inserted into a rocket hole 23 provided in the floor surface 15 is provided on the lower surface of the holder.

This pin 24 positions the guide change rail 22 so that one end of the guide change rail 22 is close to the bolster 25, and receives various forces generated on the guide change rail 22.

The guide rail 22 consists of a base member 26 made of an I-beam, a guide rail part 27, and a hanging hook 28.
slides.

The height of the position 31, which is moved from one end of the guide rail 22 to the other end by a distance shorter than half the width 30 of the pressure mold 29, is higher than the height of the upper surface of the bolster 25, and the upper surface of the guide rail section 27 has a height from position 31 to both ends. Descending inclined rail surface 32
．． 33 is formed.

Further, the height of one end of the guide change rail 22 is lower than the height of the upper surface of the bolster 25.

The aforementioned pressing die 29 is provided with a hook 34, and a wire 3 wound around a crane (not shown) is attached to this hook 34.
5 is engaged.

36 is a pulley that changes the moving direction of the wire 35.

Next, the action will be explained.

First, when carrying the pressure mold 29 into the press machine 18, the pressure mold 2
9 is placed on the other end of the change rail 22, and then the wire 35 is engaged with the hook 34.

Next, when the wire 35 is wound by a crane (not shown), the impression mold 29 moves to one end side.

When the center of gravity 37 of the press mold 29 exceeds the position 31, the press mold 29 rotates in the direction of arrow A, and since the distance from one end of the guide change rail 22 to the position 31 is shorter than half the width 30 of the press mold 29, one end of the press mold 29 moves onto the bolster 25.

When the wire 35 is further wound by a crane (not shown), the pressing die 29 is completely transferred to the bolster 25, and the waist pressing die 29 is carried into the press machine 18.

Next, when carrying out the impression mold 29 from the press machine 18, the wire 35 is engaged with the hook 34 and pulled to the other end side by a crane (not shown).

Since the height of one end of the change rail 22 is lower than the height of the upper surface of the bolster 25, the other end of the pressure mold 29 moves onto the change rail 22.

When the pressure mold 29 is further pulled toward the other end side with a crane, the pressure mold 2
9 moves on the inclined rail surface 33.32 and the press machine 18
will be removed from.

In this way, the pressing die 29 can be carried into or taken out from the press machine 18 without having to adjust the level difference or reset the setting of the guide change rail 22.

FIG. 3 shows another embodiment.

In this embodiment, the guide rail portion 27 of the guide rail 22 is placed on the guide rail 38 provided to shorten the guide change work time. shows the guide rail part 39
A roller 40 is provided on the top.

As explained above, according to this invention, the tie change rail is higher than the top surface of the bolster, and the distance from one end of the rail is shorter than half the width of the mold, and it is lowered to one end side and lowered from the top surface of the bolster. Since a sloped rail surface is formed that points downward, it is possible to eliminate the need for step adjustment due to sinking of the floor surface and the need for resetting the guide change rail.

Claims (1)

[Scope of utility model registration request] In a gui-change rail whose upper surface is a rail surface and is used by placing it on the side of a bolster when changing molds in presses, etc., the area is higher than the upper surface of the bolster and the distance from one end of the rail is less than half the width of the mold. The guide change rail is characterized in that it has an inclined rail surface that descends from the top to the one end side and is oriented lower than the upper surface of the bolster.
