Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a mold exchanging device for swiftly and simply exchanging a forging die installed in a continuous casting facility.

<Prior Art> The technology for directly forging a slab on the production line of a continuous casting facility is still new, and there is no disclosure or publicly known technology regarding a forging device and a die changing device in the field of continuous casting.

Here, description will be given on the assumption that the mold exchanging technique in the field of general casting is applied to continuous casting equipment.

FIG. 6 is a front view of the casting press, and FIG. 7 is B- in FIG.
It is a B sectional view. The upper die 1 is a dovetail groove 1a on the upper die cradle 3.
Is fixed by. The lower mold 2 is fixed to the slide table 4 by the wax method. In such a forging press, the slide table 4 is used to pull out the lower die from the forging position of C in FIG. 7 to a die exchange position of C ′ which has a sufficient working space other than the forging press to perform work. If it is possible, the mold can be easily replaced. The upper mold can also be easily replaced by lowering it with the hydraulic cylinder 12 at the position C, pulling it out to the position C ′ by taking part in the lower mold, and moving and lifting the new upper mold in the reverse order.

<Problems to be solved by the invention> However, the production line of the continuous casting machine is generally multi-strand, and there is not much space before and after the forging equipment of the production line. The method of exchanging molds has a problem that it cannot be applied in terms of space and connection.

Fig. 5 shows a diagram of equipment around the forging equipment. Reference numeral 10 denotes a pinch roll for pulling out the continuous cast piece (continuous cast piece) 11, 9 denotes a pinch roll for guiding the continuous cast piece after forging, and 5 denotes a foundation on which these equipments are mounted. In the forging pressure equipment, the crosshead 8 and the die base 13 are connected to a driving device via the crankshaft 7, and the driving device generates a forging pressure in the upper die 1 and the lower die 2. In this figure, there is only a space between the forging equipment in the L direction and the pinch roll 10 on the continuous casting side exit side, and in a multi-strand, such equipment is arranged in parallel in the C direction,
There is no space along the equipment.

Therefore, as described above, there is a problem that the mold replacement of the structure conventionally assumed cannot be applied in terms of space and connection.

The present invention has been made in order to solve the above-mentioned problems and provide a device capable of quickly and easily exchanging a mold with a small number of people.

<Means for Solving the Problems> The present invention is a mold exchanging device for a forging equipment arranged on a production line of a continuous casting equipment, and an upper die cradle in which an upper die is incorporated, An upper slide plate in which the upper die receiving base is fitted in the opening, a lower slide plate in which the lower die is directly fitted, and a metal in which the upper slide plate and the lower slide plate are wedged to each other. Continuous casting characterized in that it has a mold base, and both slide plates are slide plates in which the wedge is removed when the mold is exchanged and the mold base slides so that the die receiving part reaches the outside of the forging equipment. It is a mold exchanging device for forging equipment in the equipment, and when moving the upper and lower dies at the same time, the lower die is integrated with the upper die by the suspension rod. It is a mold changer.

<Operation> A mold exchanging device for a forging machine according to the present invention is provided with a slide plate for directly or indirectly fitting and holding a mold, and the wedge plate is wedged on a cradle for a mold. Then, the slide plate slides on the mold base so that the mold part can be easily taken out of the forging machine. The upper slide plate is provided with an opening, and the upper mold is inserted into the opening from above and fitted and held.

Therefore, the device according to the present invention does not require a wide space such as a slide table for exchanging molds in conventional general forging equipment, and can be applied to a narrow place such as a continuous casting machine line. It becomes extremely easy to attach and detach to and from the slide plate, the mold replacement time can be shortened, and the mold can be replaced by one person. Also, compared with the die exchange using only a simple handling device such as a chain block, the exchange time can be remarkably shortened and the labor saving effect is also remarkable.

In the mold exchanging device according to the present invention, if the rollers are fixed on both sides of the slide plate, the slide plate can be easily slid.
Replacing heavy molds is easier and faster.

Further, the upper die slide plate is provided with an opening, and the flange portion of the upper die or the upper die cradle is placed in this opening, so that the upper die can be easily set on the slide plate. Or can be removed.

Furthermore, by sliding the upper and lower molds integrally with the suspension rod as in claim 2, the sliding operation of the lower mold slide plate can be omitted.

<Embodiment> An embodiment according to the present invention will be described below with reference to the drawings.

As shown in FIG. 1 and FIG. 2, upper and lower mold bases 13 (1), 13
The cut grooves 13b and 13c are provided in (2), and the upper and lower slide plates 14 (1) and 14 (2) are fitted into the cut grooves 13b and 13c so that they can be slid in the horizontal direction and taken out. To do.

When setting the upper mold 1, set the upper mold 1 to the upper mold cradle 3
It is fixed in the receiving hole 14a of the and fixed by the bolt 17 and is hung by the crane in a state where it is assembled, and the upper die support 3
The flange 31 is fitted and placed on the upper slide plate 14 (1). Then remove the crane hook and slide plate 14 (1)
Is pushed into the forging device, set so as to abut on the stopper portion 13a of the upper die table 13 (1), and the cotter 15 and the like are driven to place the upper slide plate 14 (1) on the upper die table 13 (1). Fix it.

The lower die 2 is set in the same way, but the lower slide plate 14
No opening is required in (2), and it is sufficient if there is only a drop groove 14b, and the lower slide plate 14 (2) can also serve as a die receiving stand.

An improved embodiment of part D in FIG. 2 is shown in FIG. That is, by fixing the rollers 19 on both sides of the slide plate,
The sliding friction between 13 and the slide plate 14 was changed to rolling friction to facilitate the movement of the slide plate, but this is effective when the die is heavy.

Furthermore, in order to move and handle the upper and lower molds at the same time, if the lower mold is suspended from the upper mold with a suspension rod 20 as shown in FIG. This is effective when there is no space to install the mold slide plate or when the scale easily accumulates.

Conventionally, there is no suitable mold replacement device, and only a simple handling tool such as a chain block that can be used in a narrow space is used, and the molds are replaced almost manually. It took 50 minutes for one person, but according to this device, one person could replace it in 15 minutes.

<Effect of the Invention> When the mold exchanging device according to the present invention is used in the production line of the continuous casting equipment, the mold exchanging time can be shortened and the mold can be exchanged by one person.
