Description
【発明の詳細な説明】 ［産業上の利用分野］ 本発明は、連続鋳造機で連続鋳造されたスラブの幅集約
をする幅圧下連続鍛造機の圧下機構に関するものであ
る。TECHNICAL FIELD The present invention relates to a reduction mechanism of a width reduction continuous forging machine that integrates the width of a slab continuously cast by a continuous casting machine.
［従来の技術］ 連続鋳造機で鋳造されたスラブはスラブ幅の種類が少な
く、圧延により所望幅の板を製造するにはスラブの幅圧
下を行わなければならない。[Prior Art] The slab cast by a continuous casting machine has a small number of slab widths, and the width reduction of the slab must be performed in order to produce a plate having a desired width by rolling.
従来スラブの幅圧下を行う方法としては、第２図に示す
エッジャー法、第３図に示すプレス法がある。Conventional methods for width reduction of a slab include the edger method shown in FIG. 2 and the pressing method shown in FIG.
先ずエッジャー法は、スラブ１の幅端面に幅圧下ロール
２を押圧してW1からW2へ幅圧下するものである。First, in the edger method, the width reduction roll 2 is pressed against the width end surface of the slab 1 to reduce the width from W 1 to W 2 .
又、プレス法としては圧下工具を取付けた左右の圧下フ
レーム3,3を各２組のクランク4,5で支持し、クランク4,
5の回転によって圧下フレーム３を圧下作動させると共
に水平方向に配置されたクランク６によって往復動させ
ようとするものである。As the pressing method, the left and right reduction frames 3, 3 with the reduction tool attached are supported by two sets of cranks 4 and 5, respectively.
The rotation of 5 causes the reduction frame 3 to perform a reduction operation and the crank 6 arranged in the horizontal direction to reciprocate.
［発明が解決しようとする問題点］ 然し乍ら、上記エッジャー法では圧下力が板幅の中心部
に迄及ばない為大圧下をすると幅端部の上面下面に盛上
りができ所謂ドッグボーン形状となり、次工程で板厚方
向の圧延をすると幅方向に広がり幅圧下の効果が薄れて
しまう。[Problems to be Solved by the Invention] However, in the above-mentioned edger method, since the rolling down force does not reach the central portion of the plate width, a large rolling down makes it possible to build up on the upper and lower surfaces of the width end portion, forming a so-called dogbone shape, Rolling in the plate thickness direction in the next step spreads in the width direction and the effect of width reduction is diminished.
更に、プレス法ではエッジャー法で示した問題はない
が、圧下フレーム３を３組のクランクによって駆動して
いる為構造が複雑になると共に圧下フレームが大型化
し、該フレーム３の案内構造、支持構造等が複雑なもの
となる。Further, the pressing method does not have the problem shown in the edger method, but since the reduction frame 3 is driven by three sets of cranks, the structure becomes complicated and the reduction frame becomes large, and the guide structure and the support structure of the frame 3 are produced. Etc. becomes complicated.
本発明はプレス法による幅圧下連続鍛造機に於いて、そ
の圧下機構を簡略化しようとするものである。The present invention is intended to simplify the reduction mechanism in a width reduction continuous forging machine by a pressing method.

る。[Means for Solving the Problems] In the present invention, two vertical crankshafts having different phases are provided on a vertical drive shaft, and a crank having a screw down tool fixed to one end thereof is provided on one crankshaft, and the drive shaft is provided. On the other hand, a lever is rotatably provided on a shaft provided at a required distance in the slab traveling direction,
It is characterized in that a reduction unit formed by connecting one end of the lever and the other crankshaft and the other end of the lever and the lower part of the crank is arranged horizontally opposite to each other.

てクランクに圧下動作が加わり、又送りクランク軸の偏
芯回転はレバーに伝達されると共に送り動作に変換され
てクランクを往復動し、クランク先端に設けた圧下工具
はスラブの進行と同期しスラブに幅圧下を与える。[Operation] By rotating the drive shaft, a reduction operation is applied to the crank through the reduction crankshaft, and the eccentric rotation of the feed crankshaft is transmitted to the lever and converted into a feed operation to reciprocate the crank. The reduction tool provided at the tip of the crank synchronizes with the progress of the slab and applies width reduction to the slab.
［実施例］ 以下図面を参照しつつ本発明の実施例を説明する。Embodiments Embodiments of the present invention will be described below with reference to the drawings.
スラブ１に対し両幅端側方水平対向せしめて圧下ユニッ

圧下ユニット16,17は対称的な構成であり、以下は図中
下方の圧下ユニット16について説明する。The rolling-down units 16 and 17 have a symmetrical configuration, and the rolling-down unit 16 below in the drawing will be described below.
スラブ１の幅端側方に垂直な駆動軸７を設け、該駆動軸
７それぞれに圧下クランク軸８、圧下クランク軸８に対

ンク10の先端には圧下金具15を固着する。A crank 10 is rotatably attached to the reduction crank shaft 8, and a large link 11 is pivotally attached to the feed crank shaft 9. Also, a small link 12 is pivotally attached to the lower portion of the crank 10, and the small link 12 and the large link 11 are respectively provided on the upstream side of the drive shaft 7.
It is pivotally attached to both ends of a lever 14 that rotates about 13. A metal fitting 15 is fixed to the tip of the crank 10.
図中、Ａはスラブ１の進行方向、W1は圧下前のスラブ
幅、W2は圧下後のスラブ幅を示す。In the figure, A indicates the traveling direction of the slab 1, W 1 indicates the slab width before reduction, and W 2 indicates the slab width after reduction.
上下のクランクは対称的な動きをするので以下は図中下
方の圧下ユニット16についての作動の説明をする。Since the upper and lower cranks move symmetrically, the operation of the lowering unit 16 on the lower side in the drawing will be described below.

クランク軸８によってクランク10に圧下が加わると共に
送りクランク軸９によって大リンク11は右方へ移動して
レバー14を反時計方向へ揺動させ、小リンク12を介して
クランク10に図中左方への送りをかける。When the drive shaft 7 is rotated counterclockwise from the state shown in the figure, the pressure reduction crankshaft 8 applies pressure reduction to the crank 10 and the feed crankshaft 9 causes the large link 11 to move to the right to swing the lever 14 counterclockwise. Then, the crank 10 is fed to the left side in the drawing through the small link 12.
又、駆動軸７が180°回転すると圧下クランク軸８は離
反運動に転ずると共に送りクランク軸９は大リンク11に
戻り運動を与え、クランク10は小リンク12を介して戻さ
れる。When the drive shaft 7 rotates 180 °, the reduction crankshaft 8 turns into a separating motion, the feed crankshaft 9 gives a returning motion to the large link 11, and the crank 10 is returned via the small link 12.
而して、圧下金具15のＢ点の軌跡は、図中のＸの如くな
り、スラブ１の動きと同期しつつ幅圧下を行う。Thus, the locus of the point B of the reduction metal fitting 15 becomes like X in the figure, and the width reduction is performed in synchronization with the movement of the slab 1.
