本発明は、圧延月料巻取用のダウンコインに主として厚
物の銅帯を案内するためのピンチロール装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pinch roll device for guiding mainly a thick copper strip to a down coin for winding up rolling charges.
ラインパイプ用として要求される靭性や抗張力の高い厚
物鋼帯は、低温圧延で製造されるため、鋼帯トップの形
状が不安定となり、巻取設備を損傷したり、コイル形状
を極端に悪化させたりして通常のダウンコインでは巻取
ができないことがある。Thick steel strips with high toughness and tensile strength required for line pipes are produced by low-temperature rolling, which makes the shape of the top of the steel strip unstable, causing damage to winding equipment and extremely deteriorating coil shape. In some cases, it may not be possible to wind the coin with a normal down coin.

する能力は全くなく、第1図のようにロール■(が上方
へ逃げて装置を保護するにすぎなかった。Normally, when modifying the top shape of a coiled steel strip, a pinch roll located upstream of the coin is used to bend the coil to facilitate winding. In order to prevent the entire machine from being damaged by the impact, an air cylinder with a shock absorbing function is used instead of a hydraulic cylinder. Therefore, there was no ability to straighten the shape of materials such as high tensile strength steel, and the roll () merely escaped upward to protect the device, as shown in Figure 1.
従来、厚物の鋼帯などのトップ形状を修正する場合は、
ピンチロールに頼らず、長時間をかけて手作業で材料の
形状処理を行うのが通例であった。Conventionally, when modifying the top shape of thick steel strips, etc.,
It was customary to manually shape the material over a long period of time without relying on pinch rolls.

どの不都合があった。In addition, there are some bugle rolls for down coins that use a hydraulic structure to correct their shape, but the impact when biting is extremely large, causing severe damage to the equipment [7] and making repairs difficult. was there.

It is possible to obtain a pinch roll structure that can be provided.

するようにしたものである。In the vinyl roll of the present invention, when the top of the steel strip S with a defective shape arrives, as shown in FIG.
escapes upward and buffers the impact on the device, but immediately after that, a strong rolling blade with no elastic force is applied to the roll, and the roll 11 presses the top of the steel strip S strongly as shown in Figure 2. - to correct the shape. When the top of the material is wound around 1 to 5 turns by the down coiler I, the strong pressure is released, and the buffer function as shown in Fig. It was designed to be guided by a steel belt.

ール11とのギャップが変動できるようになっている。Hereinafter, the structure of the apparatus of the present invention will be specifically explained with reference to FIGS. 4 and 5. In a pinch roll with one vertical position and one vertical position, the upper pinch roll (hereinafter referred to as roll 1) is supported by a roll frame 2 that can swing vertically around a fulcrum 21. The gap with the pinch roll 11 can be changed.

ング4が連結されている。A shock absorber 6 is directly connected to the swinging end of the roll frame 2, and a liquid versiling 4 for rolling down is connected through the shock absorber.

4に作動または作動解除の指令を発する。Inside the housing 60 of the shock absorber 6 is a cylinder 40.
A slider roller 1 fixed to the tip of the rod is engaged, and a compression spring roller 2 is interposed between the slider 61 and the bottom surface of the housing 60. A load cell 63 is provided on the upper part of the housing 30, and this load cell
When a predetermined load condition acting on the hydraulic cylinder 4 is detected, a detection signal is sent to the control device w5, and the control device 5 issues a command to the hydraulic cylinder 4 to activate or deactivate it.

・圧下状態とする。A primary reduction stage and a secondary reduction stage are set in advance in the control device 5. In the case of the first reduction stage, the hydraulic cylinder 4 is not operated and the elastic force is exerted only by the spring roller 2, and in the case of the second reduction stage, the elastic force is exerted only by the hydraulic pressure.
・Put it in a compressed state.

には大きな衝撃が加わらない。Next, the operation of this device will be explained. Initially, roll 1
The case is in the first rolling stage and is waiting for the arrival of the steel plate S. Eventually, as shown in Figure 4, when the top of the deformed material comes into contact with roll 1 (C 1), the pressure impact is absorbed by the spring. 2 absorbs 1
The roll frame 2 swings upward and releases the roll 1 in the negative direction. As a result, no large impact is applied to the pinch roll device as a whole.

形状の不良を矯正する。Meanwhile, at this time, the load cell 6 detects this impact and issues a signal to the control device 5. As a result, the control unit 5 commands the cylinder 4 to operate, and the stage is switched to the secondary reduction stage shown in FIG. At this secondary rolling stage, the elastic force of the spring roller 2 is no longer present, and the slider 61 attracts the shock absorber 6 to pull down the roll frame 2. Therefore, the roll 1 strongly pushes the top of the steel strip. to correct any defects in the top shape.

その間、ロール1は2次圧下段階を保持する。During this time, the roll 1 maintains the secondary rolling stage.

In addition, an air cylinder may be used.Furthermore, as a means for detecting the passage of the top of the material, in addition to a load cell, a 1.1M+) may be installed in front of the pinch roll, or a means for detecting the passage of the material by changes in the pinch roll motor current. may also be used.

防ぐことができる。As described above, according to the one-inch roll device of the present invention, the roll-down correction function is provided only when the shape of the top of the copper strip needs to be corrected, and during other normal winding operations, the winding is performed using the elastic (E) mechanism. Since guidance can be performed, it is effective for winding high-strength materials such as thick steel strips and high-strength steel strips, and can prevent damage to the device due to impact and occurrence of miscoils.
