Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an auxiliary roller device for setting molds in a press machine.

For press machines, saving labor and shortening the time for setting press dies is an important element for improving productivity and reducing costs.

By the way, when replacing the mold in a press machine, if the mold is on the bolster plate, the lift claw cannot be inserted, and even if a crane is used, the hook will not hang, so the mold must be pulled out from the bolster plate. There is a need.

Therefore, as a means for receiving the mold pulled out from the bolster plate or before being sent to the bolster plate, conventionally,
One in which a supporting plate with rollers is supported by legs on the side of the bolster plate, and one in which a horizontal rod with rollers is attached to the side of the bolster plate so that it can rotate horizontally using a hinge at the side end. etc.

However, this has the disadvantage that the mounting position and number of support plates and horizontal bars remain constant regardless of the size and weight of the mold.

Additionally, when not in use, the support plate and horizontal rod cannot be easily removed, and even when folded they are bulky, requiring the operator to move away from the machine's working position, which not only impairs work efficiency but also increases danger. There was a problem.

The present invention relates to an auxiliary roller device for mold setting of a press machine, and is an attempt to solve the above-mentioned drawbacks of the conventional device.

In other words, the purpose is to simplify the structure, make it easy to remove when unnecessary, and also be able to slide the mounting position depending on the size and weight of the mold used, so that the mold can be placed in the optimal position and condition. An object of the present invention is to provide an auxiliary roller device for setting a mold of a press machine, which can support a mold.

The auxiliary roller device A according to the present invention will be explained below with reference to illustrated embodiments.

1 is a bracket for horizontal installation of the rail, and the bolster plate 2
Attach an appropriate number (4 in Figure 3) to the front side 3 of the port 4.
They are protruded at approximately equal intervals.

Reference numeral 5 designates an upper rail, and a strip member having a round cross section is horizontally installed on the bracket 1 so as to be parallel and horizontal with a slight distance from the front side portion 3 of the bolster plate 2.

Reference numeral 6 denotes a lower rail, and a strip member having a round cross section is horizontally installed below and parallel to the upper rail 5 by the bracket 1.

7 is a mold support rod, which consists of two horizontally long and somewhat vertically wide plates 8, 8 with an appropriate number of short pieces 9 interposed between them to form a horizontally parallel shape;
In between, an appropriate number (three in FIG. 1) of rollers 10 are provided with horizontal shafts 11 so that the upper portions thereof slightly protrude.

A notch 13 is formed near the upper side of one side of the base 12 of the support rod 7, the upper part of which slopes away from the front side 3 of the bolster plate 2, and the lower part of the notch 13 is formed so as to be connected to the upper rail 5. A semicircular upper recess 14 that can be engaged from above is formed, and the lower rail 6 is formed at the lower part through the inclined end face 15 from which the lower part approaches the bolster plate 2.
A semicircular lower recess 16 is formed which can be engaged from the side.

The positions of the upper and lower recesses 14° and 16 are
When engaged with the lower rails 5 and 6, the upper surface 17 of the support rod 7 is at the same height as the upper surface 18 of the bolster plate 2 and is in a horizontal position.

Further, a stopper 21 is provided on the other side as the tip 19 of the support rod 1, and is rotatable and erectable by a horizontal shaft 20.

The inclined notch 13 of the support rod 7 is such that when the front side of the support rod 7 is raised around the upper rail 5, the lower recess 16 separates from the lower rail 6 and the front side surface 3 of the bolster plate 2 The angle should be such that it does not hit.

Similarly, the inclined end surface 15 is set at such an angle that the lower recess 16 becomes substantially semicircular.

Next, the usage conditions and effects of the present invention will be explained with reference to the above embodiments.

This auxiliary roller device A is used when setting the mold.
When it is desired to use the support rod 7 with the roller 10 attached to the upper and lower rails 5 and 6 attached to the bolster plate 2.

As shown by the imaginary line in FIG.
If you engage the upper recess 14 of the base 12 with the upper rail 5 while slightly raising it, and lower the tip 19 side while rotating around the upper rail 5, the lower recess 16 will be connected to the lower rail 6.
engage from the side.

As a result, the upper surface 17 of the support rod 7 is installed horizontally and at the same height as the upper surface 18 of the bolster plate 2, as shown by the solid line in FIG. Similarly, against an upward force near the base, it is locked by the lower recess 16 engaged with the lower rail 6, and is not held. Never be unprepared.

Therefore, as shown in Figure 3, the support rod 7 is attached to the upper and lower rails 5 and 6.
It is sufficient to attach an appropriate number of them (three in Fig. 2).

If a mold is placed on the support rod 7 by, for example, a lift, the mold can be easily fed into the bolster plate 2 since the upper part of the roller 10 protrudes.

When a mold is placed on the support rod 7, the weight of the mold causes the support rod 7 to rotate downward using the upper rail 5 as a fulcrum, but the lower recess 16 engages the lower rail 6 from the side. And even if they are supported there, they will not back down.

In addition, if this auxiliary roller device A becomes an obstacle when performing press work after setting the mold, the lower recess 6 of the base 12 can be moved to the lower rail 16 by slightly lifting the tip 19 side of the support rod γ. The support rod 7 can be easily removed by removing it from the press and then lifting it up, so it does not interfere with the press operation.

Furthermore, when the mold on the bolster plate 2 is to be removed when replacing the mold, it can be pulled out using the rollers 10 on the horizontally installed support rod 7 in the same manner as described above, and then lowered by a lift or the like.

In particular, in the present invention, the upper and lower rails 5 and 6 are provided in a horizontally elongated shape, and the support rod 7 is provided in the upper and lower recesses 1 of the base 12.
It is provided so that it can be slid laterally along the rails 5 and 6 at an angle of 4°16.

Therefore, for example, if the mold is small, it is sufficient to slide the supporting rods 7 on both sides to position 1 near the center, which is optimal for supporting the mold, as shown by the imaginary lines in Figure 3; Correspondingly, the mold can be supported by sliding it toward both sides.

Therefore, unlike conventional models, there is no need to prepare a large number of support scale mounting members in advance to accommodate various types of molds, and by simply sliding the support rod 7, it is possible to adapt to the mold being used. so that it can always be set in the optimal position and condition.

Furthermore, if there are many small molds, for example, you can leave only the support rod near the center and remove the ones on both sides.
Even in that case, a slide closer to the center will be sufficient.

In the above embodiment, the base 12 of the support rod 7 is provided with an inclined notch 13, but the front part 3 of the bolster plate 2 is
It may also be formed closer to the top.

Further, since the upper rail 14 only needs to be able to rotate a little when the upper recess 14 of the support rod 7 is engaged and removed, only the upper half of the upper rail 14 may have a circular shape, and the cross-sectional shape of the lower rail 6 does not matter, and the lower recess 16 may be formed from the upper recess 16 through the vertical end surface 15, although the area of contact with the lower rail 6 is small, as shown in FIG.

Further, in the above embodiment, the auxiliary roller device A is provided on the front side portion 3 of the bolster plate 2, but it may be provided on the side portion 22 of the bolster plate 2 depending on the model of the press machine.

As is clear from the above, the auxiliary roller device according to the present invention has a simple structure, unlike conventional devices of this kind, and the support rod can be easily attached and removed, and it can also be slid along the rail. .

Therefore, by removing the mold support rod when not in use, press work can be carried out efficiently without any obstructions.

In particular, unlike conventional molds, the support rod can be slid to the optimal position to support the mold, depending on the size and weight of the mold being used.

Therefore, the mounting position is not limited to the position of a pre-fixed support scale mounting member, unlike the conventional case.

In addition, in order to accommodate dog and small molds, it is no longer necessary to provide a large number of support scale attachment members in advance, unlike in the past.

Furthermore, instead of having to remove and reinstall each time according to the mold used, as in the past, it is only necessary to simply slide the already installed support rod, making the work easy and quick. It has the following useful effects.
