Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an opposed type running width press in a rolling line.

[Prior Art] A conventional opposed running width press described in JP-A-62-68646 will be described with reference to FIG.

In the guide portion 3 of the housing 2 provided on both sides of the slab 1,
Slab 1 A pair of travel guides 4 that can slide in the longitudinal direction
And a cylinder 5 that expands and contracts in the longitudinal direction of the slab 1 is connected to each travel guide 4.

A hollow slide guide portion 6 extending in the width direction of the slab 1 is formed inside the travel guide 4, and a predetermined gap 7 is formed between the slide guide portions 6 inside each slide guide portion 6.
Spherical pressure receiver attached to the tip of a rod 10 of an eccentric mechanism 9 for converting rotational motion into reciprocating motion in the width direction of the slab 1 at the portion opposite to the slab 1 side of the press slide 8 11 is attached via a spherical seat 12 and a pressing plate 13, and a mold 14 is attached to the slab side surface of the press slide 8.

Reference numeral 15 indicates the center of rotation of the eccentric mechanism 9, 16 indicates an eccentric portion, and the length of the rod 10 can be adjusted to cope with changes in the width dimension of the slab 1.

Such an opposition type running width press expands and contracts the cylinder 5 and reciprocates the travel guide 4 in the longitudinal direction of the slab 1, thereby feeding the mold 14 in the longitudinal direction in synchronization with the slab 1 and at the same time, an eccentric mechanism. By rotating 9 and reciprocating the press slide 8 in the width direction of the slab 1 via the rod 10, the die 14 can be moved toward and away from the slab 1 to perform width pressing.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional opposed type running width press, the slide guide portion 6 of the travel guide 4 and the press slide 8 are provided.
Are in surface contact with each other, so that in order to prevent galling between them and ensure smooth movement of the press slide 8 in the width direction of the slab 1, a predetermined distance is provided between the slide guide portion 6 and the press slide 8. There was a problem that the gap 7 had to be provided.

Therefore, when an impact is applied to the mold 14 during pressing, rattling of the press slide 8 due to the gap 7 occurs, which causes vibration and noise, and the press slide 8 is biased in the gap 7. There has been a problem that galling occurs and causes wear.

Further, since the gap 7 is narrow for inserting the press slide 8 into the travel guide 4, it is difficult to replace the mold 14.

In view of the above-mentioned circumstances, the present invention has an object to provide an opposed type running width press capable of preventing vibration and noise generation and abrasion due to galling and facilitating die replacement work. is there.

[Means for Solving the Problems] According to the present invention, a rolling member is provided on an upstream side or a downstream side of a slide guide portion of a travel guide in a slab feeding direction, and a press slide is provided on a side of the slide guide portion facing the rolling member. The present invention relates to an opposed-type running width press, which is characterized in that a pressing device having a roller that presses against a rolling member is provided.

[Operation] Since the press slide is pressed toward the rolling member by the pressing device provided with the rollers, rattling is prevented, noise and vibration are generated, and abrasion due to galling is prevented.

Therefore, the gap of the slide guide portion formed in the travel guide with respect to the press slide can be set to be large, so that the press slide can be easily inserted and the die replacement work can be facilitated.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, in which the same reference numerals as in FIG. 2 represent the same parts.

Slide guide part 6 formed inside the travel guide 4
On the surface of the slab 1 on the upstream side in the feeding direction, a wedge surface 17 is formed which approaches the side surface of the press slide 8 as it approaches the slab 1, and between the wedge surface 17 and the side surface of the press slide 8 facing the wedge surface 17. , The wedge member 20 is engaged with the wedge member 20, and the wedge member 20 is fixed to the travel guide 4 in a position adjustable in the width direction of the slab 1.

Further, the rolling member 19 is interposed between the wedge member 20 and the side surface of the press slide 8.

In the figure, the rolling member 19 is attached to the wedge member 20.

A mounting hole 21 extending in the longitudinal direction of the slab 1 is formed at least at two positions in the width direction of the slab 1 on the surface of the slide guide portion 6 on the downstream side in the slab 1 feeding direction, and the rod of the cylinder 22 is provided.
23 The roller 24 is rotatably held at the tip of the
Is fixed in the mounting hole 21 and the roller 24 is provided so as to project toward the slide guide 6 side. The press slide 8 is connected to the roller 24 and the wedge member 20 by extending the cylinder 22 in the longitudinal direction of the slab. To be able to hold between.

Before operating the opposed type travel width press, the press slide 8 is inserted into the slide guide portion 6 inside the travel guide 4, and the wedge having the rolling member 19 between the wedge surface 17 and the side surface of the press slide 8. Wedge member that wedges member 20
Secure 20 to the travel guide. At this time, the rolling member 19
The slab 1 of the press slide 8 is adjusted such that the gap between the tip of the slab 1 and the surface of the slide guide portion 6 on the downstream side in the feed direction of the slab 1 is wider than the dimension of the slab 1 in the longitudinal direction of the press slide 8 by a gap 7. To ensure smooth mobility in the width direction.

By doing so, the press slide 8 can be easily inserted into the slide guide portion 6, and the work of exchanging the mold 14 can be facilitated.

In this state, the cylinder 22 of the pressing device 25 is extended, and the roller 24 presses the press slide 8 toward the wedge member 20.

After that, when the cylinder 5 is expanded / contracted and the eccentric mechanism 9 is rotationally driven to operate the opposed travel width press, the press slide 8 is pressed by the pressing device 25, so rattling is prevented, and noise and vibration are prevented. Occurrence and wear due to galling are prevented. Further, since the press slide 8 is slidably rolled by the rolling member 19 between the press slide 8 and the wedge member 20, smooth mobility can be obtained and galling of the wedge member 20 and the like can be prevented.

Incidentally, the opposed traveling width press of the present invention is not limited to the above-mentioned embodiment, and the wedge member and the pressing device may be provided either upstream or downstream of the slide guide portion in the slab feed direction. Of course, parallel members may be used in place of the wedge member, and various changes may be made without departing from the scope of the present invention.

[Advantages of the Invention] As described above, according to the opposed-type travel width press of the present invention, since the pressing device is provided, it is possible to prevent rattling of the press slide, thereby preventing noise and vibration. It is possible to prevent the abrasion due to the generation and the galling, and further it is possible to facilitate the replacement of the mold, which is an excellent effect.
