Description

本発明は、鋼板製造工程において、鋼板の両端部を切断して規定幅にするサイドトリマなどの切断装置によって切断された切断面を切削する、鋼板の端面機械加工方法及び装置に関する。   The present invention relates to a steel plate end surface machining method and apparatus for cutting a cut surface cut by a cutting device such as a side trimmer that cuts both ends of a steel plate to a specified width in a steel plate manufacturing process.

従来、鋼板の端面機械加工方法として、冷間圧延材の切断エッジ部を、酸洗槽と冷間圧延工程間に設置した押圧ローラ装置により板幅方向に圧潰加工して、破断面の微少クラックを除去する方法が開示されている(例えば特許文献1)。
また、他の方法として、鋼板の両側に刃先のすくい角αが20〜60°のバイトを、その刃先が鋼板端面に切り込むように保持して、鋼板とバイトを相対移動させ、鋼板の両端面を同時に切削する方法が開示されている(例えば特許文献2)。
Conventionally, as a method for machining the end face of a steel sheet, the cut edge portion of the cold rolled material is crushed in the sheet width direction by a pressing roller device installed between the pickling tank and the cold rolling process, and a micro crack on the fracture surface Has been disclosed (for example, Patent Document 1).
In addition, as another method, holding a cutting tool having a rake angle α of 20 to 60 ° on both sides of the steel sheet so that the cutting edge cuts into the end face of the steel sheet, the steel sheet and the cutting tool are moved relative to each other, and both end faces of the steel sheet Has been disclosed (for example, Patent Document 2).

特開昭56−91911号公報JP-A-56-91911 特許第3691130号公報Japanese Patent No. 3691130

従来の方法、例えば上記圧潰方法では、サイドトリマによる鋼板の切断面が平滑とは限らず、また微少クラックが含まれる破断面側の切断面が、剪断面に対して凹状になっていることもあるため、ローラにて所要の押圧力を付与するだけで、破断面の微少クラックやバリなどを完全に除去することは困難である。
また、例えば上記鋼板の両側に刃先のすくい角αが20〜60°のバイトを保持して行う切削方法では、バイトの刃先が磨耗していくと、すくい角20〜60°を維持することができず、所望の効果を発揮することは困難である。
In the conventional method, for example, the above-described crushing method, the cut surface of the steel plate by the side trimmer is not necessarily smooth, and the cut surface on the fracture surface side including the minute cracks may be concave with respect to the shear surface. For this reason, it is difficult to completely remove microcracks, burrs, and the like on the fracture surface simply by applying a required pressing force with a roller.
Further, for example, in a cutting method performed by holding a cutting tool having a rake angle α of 20 to 60 ° on both sides of the steel plate, the rake angle of 20 to 60 ° may be maintained when the cutting edge of the cutting tool is worn. It is difficult to achieve the desired effect.

本発明は上記のような課題に対応するためになされたものであり、サイドトリマなどの切断装置によって切断された鋼板端面を平滑にして、切断端面の微少クラックやエッジ部のバリなどを除去するとともに、バイトの長寿命化も可能な鋼板の端面機械加工方法及び装置を提案することを目的とする。   The present invention has been made to cope with the above-described problems, and smoothes the steel plate end surface cut by a cutting device such as a side trimmer to remove minute cracks on the cut end surface, burrs on the edge portion, and the like.

なお、前記鋼板の各端面の板厚方向に異なる角度で配置された2つ以上の前記円形バイトを利用して、各端面を切削することが好ましい。
また、前記円形バイトを前記鋼板の移動力及び前記端面の切削反力により従動回転させることが好ましい。

なお、前記円形バイトを、前記鋼板の各端面の板厚方向に異なる角度で2つ以上配置していることが好ましい。
また、前記円形バイトが前記鋼板の移動力及び前記端面板の切削反力により従動回転させられることが好ましい。

以下に、本発明の実施の形態について図面を参照して説明する。本発明に係る鋼板の端面機械加工装置は、例えば酸洗冷間圧延連続ラインに適用できる。図1は本発明に係る端面機械加工装置を備えた鋼板の酸洗冷間圧延連続ラインの一例を示す図である。図1の酸洗冷間圧延連続ラインは、前製造工程で板厚約200mmの厚板スラブを熱間圧延機によって板厚約4mm程度に熱間圧延し製造されたコイル状の熱間圧延鋼板1aを繰出し端2とし、この繰出し端2から繰出される熱間圧延鋼板1aを、熱間圧延工程で生じたスケールを除去するための酸洗処理工程である酸洗槽3を通して酸洗処理した後、サイドトリマ4によって規定幅に切断する。その後、サイドトリマ4によって切断された切断端面を切削する端面機械加工装置5により鋼板1aの切断端面を平滑化し、さらに冷間圧延機群6により冷間圧延することで、鋼板1aを板厚1mm程度の冷間圧延鋼板1bとした後、巻取り端7に巻き取って、冷間圧延コイルを製造する工程である。
なお、冷間圧延コイルは、出荷品種に応じて次工程に移され、連続焼鈍処理や鍍金処理が行われる。
Embodiments of the present invention will be described below with reference to the drawings. The steel plate end surface machining apparatus according to the present invention can be applied to, for example, a pickling and cold rolling continuous line. FIG. 1 is a view showing an example of a pickling and cold rolling continuous line of a steel plate provided with an end face machining apparatus according to the present invention. The pickling and cold rolling continuous line in FIG. 1 is a coiled hot rolled steel plate manufactured by hot rolling a thick plate slab having a thickness of about 200 mm to about 4 mm by a hot rolling mill in the previous manufacturing process. The hot rolled steel sheet 1a fed from the feeding end 2 is pickled through the pickling tank 3 which is a pickling treatment process for removing scales generated in the hot rolling process. After that, it is cut to a specified width by the side trimmer 4. Thereafter, the cut end face of the steel plate 1a is smoothed by the end face machining device 5 for cutting the cut end face cut by the side trimmer 4, and further cold-rolled by the cold rolling mill group 6, so that the steel plate 1a has a plate thickness of 1 mm. This is a step of manufacturing a cold-rolled coil by making a cold-rolled steel sheet 1b of a certain degree and then winding it on the winding end 7.
The cold-rolled coil is moved to the next process according to the shipment type, and subjected to continuous annealing and plating.

図2は上記酸洗冷間圧延連続ラインに組み込まれた本発明の実施形態に係る端面機械加工装置5の詳細構成を示す平面図、図3は本発明の実施形態に係る端面機械加工装置5の詳細構成を示す側面図である。図2及び図3に示すように、端面機械加工装置5は、例えば片側にそれぞれ2つの回転自在な円形バイト15a,15b及び16a,16bを備え、その刃先を、サイドトリマ4などの切断装置によって切断された鋼板1aの切断端面に切り込むように押し当てて保持し、該切断端面を切削するようにしたものである。   FIG. 2 is a plan view showing a detailed configuration of the end face machining apparatus 5 according to the embodiment of the present invention incorporated in the pickling cold rolling continuous line, and FIG. 3 is an end face machining apparatus 5 according to the embodiment of the present invention. It is a side view which shows the detailed structure. As shown in FIGS. 2 and 3, the end surface machining apparatus 5 includes, for example, two rotatable circular cutting tools 15 a, 15 b and 16 a, 16 b on one side, and the cutting edge thereof is cut by a cutting device such as a side trimmer 4. The cut end face is pressed and held so as to cut into the cut end face of the cut steel sheet 1a, and the cut end face is cut.

端面機械加工装置5は、サイドトリマ4の後段に設置されており、サイドローラ11a,11bと、サイドローラ11a,11bを鋼板端面に押付けるシリンダ12a,12bと、鋼板1aの上下面を拘束するピンチロール13,14と、鋼板1aの端面を切削加工する円形バイト15a,15b,16a,16b(15a〜16b)と、これらの円形バイトを板幅方向に進退駆動させる進退駆動装置17a,17bと、進退駆動装置17a,17bが設置され、サイドローラ11a,11bと連動して板方向にリニアガイド19に沿って可動する工具台18a,18bとから構成されている。   The end surface machining device 5 is installed in the rear stage of the side trimmer 4 and restrains the side rollers 11a and 11b, the cylinders 12a and 12b that press the side rollers 11a and 11b against the end surface of the steel plate, and the upper and lower surfaces of the steel plate 1a. Pinch rolls 13 and 14, circular cutting tools 15a, 15b, 16a and 16b (15a to 16b) for cutting the end face of the steel plate 1a, and advancing and retracting driving devices 17a and 17b for driving these circular cutting tools back and forth in the plate width direction; The forward / backward drive devices 17a and 17b are installed, and are composed of tool bases 18a and 18b movable along the linear guide 19 in the plate direction in conjunction with the side rollers 11a and 11b.

この端面機械加工装置5は、サイドローラ11a,11bを鋼板1a端面に接触させながら、進退駆動装置17a,17bを制御して、円形バイト15a〜16bの鋼板端面への切込み量の調整を行う。従って、サイドローラ11a,11bは、円形バイトを鋼板1aに対して位置決めする際、進退駆動装置17a,17bと共に位置決め手段として作用する。このように、円形バイト15a〜16bの刃先が、鋼板端面に切り込むように押し当てて保持し、鋼板1aを移動させ、円形バイト15a〜16bを回転させながら、鋼板1aの両端面を切削する。なお、その切削量は、端面が平滑化でき、端面からクラックなどを除去できる量であり、例えば低炭素径の鋼板の場合で、0.3mm程度である。   The end surface machining device 5 controls the advance / retreat drive devices 17a and 17b while the side rollers 11a and 11b are in contact with the end surface of the steel plate 1a, thereby adjusting the cutting amount of the circular cutting tools 15a to 16b into the end surfaces of the steel plate. Therefore, the side rollers 11a and 11b act as positioning means together with the advance / retreat drive devices 17a and 17b when positioning the circular cutting tool with respect to the steel plate 1a. In this way, the cutting edges of the circular cutting tools 15a to 16b are pressed and held so as to cut into the end faces of the steel sheet, the steel sheet 1a is moved, and both end faces of the steel sheet 1a are cut while rotating the circular cutting tools 15a to 16b. The amount of cutting is such that the end face can be smoothed and cracks can be removed from the end face. For example, in the case of a steel sheet with a low carbon diameter, it is about 0.3 mm.

この端面機械加工装置5を利用した鋼板1aの端面加工は、例えば、鋼板1aの両端面の一方の端面側に直径10mm程度の小径の円形バイト15aと16aを、他方の端面側に同じく小径の円形バイト15bと16bを鋼板1aの板厚方向に対称配置し、それぞれの刃先が鋼板1a端面の上下エッジに接触するようにして行う。これにより、エッジ部にバリやかえりを発生させずに、鋼板1aのサイドトリマ切断面の破断面内を平滑化して、破断面内に発生した微小クラックなどを除去することできる。   The end face processing of the steel sheet 1a using the end face machining apparatus 5 is performed, for example, by using small diameter circular cutting tools 15a and 16a having a diameter of about 10 mm on one end face side of the both end faces of the steel sheet 1a and the same small diameter on the other end face side. The circular cutting tools 15b and 16b are arranged symmetrically in the plate thickness direction of the steel plate 1a, and the respective cutting edges are in contact with the upper and lower edges of the end surface of the steel plate 1a. Thereby, the inside of the fracture surface of the side trimmer cut surface of the steel plate 1a can be smoothed without generating burrs or burr at the edge portion, and the micro cracks or the like generated in the fracture surface can be removed.

なお、鋼板1aの板厚は例えば4mm程度であり、加工効率を上げるために円形バイト15a〜15b,16a〜16bの径を大きくする(例えば直径100mm)場合は、上下の円形バイトを図3のように対称に配置するのは困難となる。そこで、径の大きな円形バイトを設置する場合は、図4に示すように、鋼板1aの長手方向(=搬送方向)にオフセットした位置に配置することで対応すればよい。   In addition, the plate | board thickness of the steel plate 1a is about 4 mm, and when raising the diameter of the circular cutting tools 15a-15b and 16a-16b in order to raise processing efficiency (for example, diameter 100mm), upper and lower circular cutting tools are shown in FIG. Thus, it becomes difficult to arrange them symmetrically. Therefore, when installing a circular cutting tool with a large diameter, as shown in FIG.

図3及び図4では、片側端面に2つの円形バイトを設置した例を示したが、大きな径(例えば直径100mm程度)の円形バイトを、鋼板の片側端面に1つ配置する態様としても良い。
図5は鋼板の片側端面に1個の円形バイトを設置した場合のバイトと鋼板との位置関係を示した説明図である。この場合、図示するように、鋼板の搬送方向に対する円形バイトの傾きは、45度程度とする。また、円形バイトの刃先のすくい角は0〜15度の範囲とするのが好ましい。
なお、円形バイトの鋼板に対する傾斜角、鋼板長手方向への複数配置(多段化)等については必要に応じて適宜設計変更が可能である。
3 and 4 show an example in which two circular cutting tools are installed on one end face, but one circular cutting tool having a large diameter (for example, about 100 mm in diameter) may be arranged on one end face of the steel plate.
FIG. 5 is an explanatory view showing the positional relationship between the cutting tool and the steel plate when one circular cutting tool is installed on one end face of the steel plate. In this case, as shown in the drawing, the inclination of the circular cutting tool with respect to the conveying direction of the steel sheet is about 45 degrees. Further, the rake angle of the cutting edge of the circular cutting tool is preferably in the range of 0 to 15 degrees.
In addition, about the inclination | tilt angle with respect to the steel plate of a circular bite, multiple arrangement | positioning (multistage formation), etc. to a steel plate longitudinal direction, design change is possible suitably as needed.

ところで、各円形バイトは、電動機などを利用して回転させても良いが、鋼板の移動力(搬送力)及び端面の切削反力を受けて従動回転させるようにしておくと、端面機械加工装置の設備が簡素化できるので好ましい。図6は片側端面に設置した1個の円形バイトが、鋼板の移動力及び切削反力を受けて従動回転することを説明する斜視図である。この図6の場合には、鋼板の移動力及び切削反力を受けて、円形バイトが反時計回りに従動回転している。このように円形バイトを回転させながら端面の切削を行うことで、円形バイトと鋼板端面の接触部が逐次変わり、バイトの発熱、摩耗を防止することができる。   By the way, each circular tool may be rotated by using an electric motor or the like, but if it is driven and rotated by receiving the moving force (conveying force) of the steel plate and the cutting reaction force of the end surface, the end surface machining device This is preferable because the equipment can be simplified. FIG. 6 is a perspective view illustrating that one circular cutting tool installed on one end face rotates following a moving force and a cutting reaction force of a steel plate. In the case of FIG. 6, the circular cutting tool is driven to rotate counterclockwise in response to the moving force and cutting reaction force of the steel plate. By cutting the end face while rotating the circular cutting tool in this way, the contact portion between the circular cutting tool and the end surface of the steel sheet is changed sequentially, and the heating and wear of the cutting tool can be prevented.

図7は鋼板1aの片側端面に2個の円形バイトを設置した場合に、該円形バイトが端面を切削する状況を示す鋼板搬送方向の下流側から見た側面図、図8は図7の鋼板端面と円形バイトの接触態様を説明する模式図である。この例の場合、厚さ4mmの鋼板端面の下端部が下側に配置された円形バイトにより切削され、鋼板端面の上端部が上側に配置された円形バイトにより切削される。鋼板端部への円形バイト外周部の当たり角θは、90度以下の鋭角となる。そして、鋼板端面が図中の円弧状に切削される。なお、図中の点線は切削前の鋼板端部の輪郭を表している。
図7、8に示したように、鋼板端面の片側に円形バイトを板厚方向に対して2つ以上配置することで、鋼板端面のエッジ部にバリを発生させない機械加工が確実に実現できる。
FIG. 7 is a side view seen from the downstream side in the steel plate conveyance direction showing the situation where the circular cutting tool cuts the end face when two circular cutting tools are installed on one end face of the steel plate 1a, and FIG. 8 shows the steel plate of FIG. It is a schematic diagram explaining the contact aspect of an end surface and a circular cutting tool. In the case of this example, the lower end portion of the 4 mm thick steel plate end surface is cut with a circular cutting tool arranged on the lower side, and the upper end portion of the steel plate end surface is cut with a circular cutting tool arranged on the upper side. The contact angle θ of the outer periphery of the circular cutting tool with respect to the end of the steel plate is an acute angle of 90 degrees or less. And the steel plate end surface is cut into the circular arc shape in a figure. In addition, the dotted line in a figure represents the outline of the steel plate edge part before cutting.
As shown in FIGS. 7 and 8, by arranging two or more circular cutting tools on one side of the end face of the steel sheet in the thickness direction, machining that does not generate burrs at the edge of the end face of the steel sheet can be reliably realized.
