Description

Description: FIELD OF THE INVENTION The present invention relates to an improvement of a horizontal facing press apparatus for reducing the width of a material between runs in a rolling line or a continuous casting line, and relates to driving of a press mechanism and a transport mechanism. Is driven by one driving device, and only the transport mechanism can be driven independently.

[Background Art] As a device capable of efficiently reducing the width of a material such as a slab, a horizontally opposed type running press device is known.

This horizontal facing type running press device mounts a mold that can reciprocate in a direction orthogonal to the material conveyance direction on a traveling guide block that can reciprocate in the material conveyance direction, and synchronizes the material and the mold. While moving the material, press forming such as width reduction of the material is performed (Japanese Patent Application Laid-Open No. 62-151224).
Reference).

As shown in FIG. 1, one example of a specific configuration of the horizontal facing type running press is a pair of slides provided with a pair of dies 1, 1 opposed to both sides of the slab S in the transport direction T. The slides 2 and 2 are connected to a crankshaft 4 constituting a press mechanism 3 via a connecting rod 5 so that the slides 2 and 2 can reciprocate in the width direction of the slab S. further,
The slides 2, 2 are movably supported by a travel guide 6 provided along the transport direction of the slab S,
After the width reduction, the dies 1 and 1 can be returned to the upstream side in the transport direction by the cylinder mechanism 7.

Also, the dies for transferring the slab S between the dies 1, 1
Pinch rolls 9, 9 constituting the transport mechanism 8 are provided on the entry side of 1, 1, and a roller table 10 is installed upstream of the pinch rolls 9, 9.

In order to drive the crankshaft 4 of the press mechanism 3 and the pinch rolls 9 of the transport mechanism 8, a single motor 12 is provided as a drive device 11. The pinch rolls 9 and 9 are driven via 14 and a bevel gear 15, while the other pinion 16 of the motor 12 drives the crankshaft 4 via a gear mechanism 17 and an intermediate shaft 18.

Therefore, by moving the motor 12 of the driving device 11, the slab S is conveyed by the pinch rolls 9, 9, and at the same time, the crankshaft 4 is rotated, and the slab S is sandwiched between the dies 1, 1 during the running. The width is reduced.

For this reason, it is easy to carry out the synchronous drive of the conveyance of the slab S by the pinch rolls 9, 9 and the press forming by the crankshaft 4,
There is a feature that the structure of the drive system is simplified.

[Problems to be Solved by the Invention] However, in such a horizontally opposed type running press, one drive device 11 drives the crankshaft 4 of the press mechanism 3 and the pinch rolls 9 and 9 of the transfer device 8. Therefore, when it is not necessary to press-form a part of the slab S due to a change in the forming process or the like, when the pinch rolls 9, 9 are driven to convey only the slab S, the crankshaft 4 is simultaneously rotated. As a result, there is a problem that only the slab S cannot be transported.

The present invention has been made in view of the problems of the related art, and aims at simplifying a driving system by using a single driving device, and at the same time, a horizontal facing press capable of performing only material conveyance. It is intended to provide a device.

Means for Solving the Problems In order to solve the problems of the above-described conventional technology, the present invention is a horizontally opposed press device that reduces the width of a material between runs, and faces each other across a material transport direction. A press mechanism for reciprocating a slide having a pair of dies in a direction perpendicular to the conveyance direction, and a conveyance mechanism for conveying a material between the pair of dies;
A driving device capable of driving the press mechanism and the transport mechanism, and a disengagement mechanism which is interposed between the press mechanism and the drive device and which can independently drive only the transport mechanism by disengaging a driving force. Means.

[Operation] According to this horizontally opposed press device, the drive mechanism that can independently drive only the transport mechanism between at least the press mechanism and the drive device of the press mechanism and the transport mechanism driven by one drive device. It is designed to provide engaging and disengaging means such as a clutch for engaging and disengaging the force, so that only the material can be transported without pressing the material, and energy is saved as compared with the case where other transporting devices are attached. The range of press molding can be expanded.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic configuration diagram according to an embodiment of a horizontally opposed press device of the present invention.

As described above, the horizontal facing press device includes, as described above, the press mechanism 3, the transport mechanism 8, and the driving device.
11 and are provided.

In the press mechanism 3, dies 1, 1 are attached to a pair of slides 2, 2 on both sides of the slab S in the width direction (both sides in the direction perpendicular to the direction of conveyance), and the driving force is transmitted by the crankshaft 4 and the connecting rod 5. The width of the slab S can be reduced.

The transport mechanism 8 includes pinch rolls 9, 9,
The slab S can be transported by sandwiching the slab S from above and below.

A driving device 11 drives the crankshaft 4 of the press mechanism 3 and the pinch rolls 9 of the transport mechanism 8.
One motor 12 is provided, and two pinions 13 and 16 are attached to the output shaft.

In this embodiment, the pinch rolls 9, 9
Is always driven regardless of whether the slab S needs to be reduced in width or not.
A gear mechanism 14 meshes with the pinch 13, and pinch rolls 9, 9 are directly connected via a bevel gear 15.

A gear mechanism 17 is meshed with the other pinion 16 of the motor 12 so as to be decelerated,
A clutch 20 which constitutes engaging / disengaging means 19 is provided between an output shaft 17a of the gear mechanism 17 and an intermediate shaft 18 for transmitting power to the crankshaft 4.
And the intermediate shaft 18 and the crankshaft 4 are connected. Further, a braking device is provided at the other end of the crankshaft 4.
21 is provided so that the stopped state of the crankshaft 4 can be maintained.

The running press forming and transport by the horizontally opposed press apparatus configured as described above are performed as follows.

When performing press molding during running.

Since it is necessary to drive the press mechanism 3 simultaneously with the transport mechanism 8, the clutch 20 of the engagement / disengagement means 19 is engaged and the brake device 21 at the end of the crankshaft 4 is released.

After the preparation is completed, the driving force is transmitted to the pinch rolls 9, 9 of the transport mechanism 8 via the pinion 13, the gear mechanism 14, and the bevel gear 15 by moving the motor 12 of the drive device 11, and the slab S is transported. At the same time, the pinion 16 → the gear mechanism 17 → the output shaft 17a → the clutch 20 of the engaging / disengaging means 19 → the crankshaft 4 of the press mechanism 3 via the intermediate shaft 18
When the slab S is sandwiched between the dies 1 and 1, the width is reduced during the run.

When only the slab S is transported.

Since it is not necessary to drive the press mechanism 3, the clutch 20 of the engagement / disengagement means 19 is released, and the brake device 21 at the end of the crankshaft 4 is engaged.

After that, when the motor 12 of the drive device 11 is moved, the pinion 13 → the gear mechanism 14 →
The driving force is transmitted via the bevel gear 15, and the slab S is conveyed.

However, the press mechanism 3 has a pinion 16 → gear mechanism 17
The driving force is transmitted between the output shaft 17a and the clutch 20 of the engagement / disengagement means 19, but the driving force is not transmitted after the intermediate shaft 18, and the crankshaft 4 is in a braking state. The dies 1, 1 and the sliders 2, 2 do not operate, and press molding is not performed.

In this manner, by operating the clutch 20 of the engaging / disengaging means 19 to disengage the driving force from the driving device 11, only the slab S, which is the material, can be transported, and the width of the material remains unchanged from the raw material. In such a case, only the transport mechanism 8 can be operated.

Therefore, as compared with a case where a separate driving device is provided, energy can be saved, only the material can be transferred, and the shape range by press molding can be expanded.

In the above-described embodiment, the case where the clutch is used as the engagement / disengagement means has been described. However, the invention is not limited to this.

Energy saving compared to
The range of shapes that can be formed by press molding can be expanded.
