Description

本発明は、棒材の横断面形状の検査と長手方向の曲がり検査を同時に行なう装置に関するものである。   The present invention relates to an apparatus for simultaneously inspecting a cross-sectional shape of a bar and bending inspection in a longitudinal direction.

条鋼製品である棒材は、熱間の圧延ライン内で切断された後、冷間で曲がりが矯正され、形状検査をされた後、客先に出荷される。
従来、このような形状検査は、特許文献1のような装置で行われていた。
実開昭61−72608 号公報
After being cut in a hot rolling line, the bar material, which is a long steel product, is bent in a cold state, subjected to shape inspection, and then shipped to a customer.
Conventionally, such a shape inspection has been performed by an apparatus such as that disclosed in Patent Document 1.
Japanese Utility Model Publication No. 61-72608

出荷後の棒材1は、客先で、図3に示す円筒バイト2aと上バイト2bによって切断されるものがある。図3中の3は棒材1の切断長さ調整用ストッパーである。
このような円筒バイトを用いて切断しようとした場合、棒材1の切断端部断面の真円度が劣ると、切断しようとする棒材が、円筒バイトの中で詰まってしまうという不具合が発生する。
The bar 1 after shipment may be cut at the customer by a cylindrical cutting tool 2a and an upper cutting tool 2b shown in FIG. 3 in FIG. 3 is a stopper for adjusting the cutting length of the bar 1.
When trying to cut using such a cylindrical cutting tool, if the roundness of the cut end section of the bar 1 is inferior, the bar to be cut will be clogged in the cylindrical cutting tool. To do.

一方、出荷前の棒材の切断は熱間において剪断加工で行われるため、その切断された端部は楕円形状になり易く、棒材の長手方向中央部の真円度は良好であっても、その端部の真円度が劣るために、その横断面形状を厳しく管理する必要があった。   On the other hand, since the cutting of the bar material before shipment is performed by shearing in the hot state, the cut end portion tends to be elliptical, and the roundness of the central portion in the longitudinal direction of the bar material is good. Since the roundness of the end portion is inferior, it is necessary to strictly manage the cross-sectional shape.

しかしながら、特許文献1で開示された技術は、曲がり(真直性)検査のためのものであるため、ある程度余裕をもった外径許容値を確保せざるを得ず、そのため、厳しい横断面形状の検査を曲がり(真直性)検査と同時に要求される場合には、対応することができなかった。   However, since the technique disclosed in Patent Document 1 is for bending (straightness) inspection, it is necessary to secure an allowable outer diameter with a certain margin, and therefore, a severe cross-sectional shape is required. When the inspection was required at the same time as the bending (straightness) inspection, it could not be dealt with.

本発明の目的は、曲がりだけでなく、厳しい横断面形状を保証するための検査を行なうことができる装置を提供することにある。   An object of the present invention is to provide an apparatus capable of performing an inspection for assuring a severe cross-sectional shape as well as bending.

以下、本発明を実施するための一形態と共に最良の形態について、図1及び図2を用いて詳細に説明する。
図1は本発明の棒材の検査装置の最良の形態を説明する図、図2は本発明の棒材の検査装置の他の形態を説明する図である。
Hereinafter, the best mode as well as one mode for carrying out the present invention will be described in detail with reference to FIGS.
FIG. 1 is a view for explaining the best mode of the bar inspection apparatus of the present invention, and FIG. 2 is a view for explaining another mode of the bar inspection apparatus of the present invention.

図1及び図2において、11は被検査材である棒材1の、曲がり矯正後の曲がり検査と、横断面形状、すなわち外径の上限寸法を保証するための検査を同時に行なう本発明の棒材の検査装置であり、以下のような構成である。   1 and 2, reference numeral 11 denotes a bar of the present invention that simultaneously performs a bending inspection after bending correction of a bar 1 as a material to be inspected and an inspection for assuring an upper limit dimension of a cross-sectional shape, that is, an outer diameter. This is a material inspection device having the following configuration.

12は棒材1の曲がり矯正後の曲がり検査部(以下、曲がり検査部という。)、13は外径の上限寸法を保証するための検査部(以下、外径上限寸法検査部という。)である。そして、本発明の棒材の検査装置11は、これら両検査部12,13が、棒材1の搬送方向に所定の間隔を存して、かつ外径上限寸法検査部13が搬送方向上流側となるように配置された構成である。   Reference numeral 12 denotes a bending inspection section (hereinafter referred to as a bending inspection section) after correcting the bending of the bar 1, and reference numeral 13 denotes an inspection section (hereinafter referred to as an outer diameter upper limit dimension inspection section) for assuring the upper limit of the outer diameter. is there. In the bar inspection apparatus 11 according to the present invention, both the inspection units 12 and 13 have a predetermined interval in the conveyance direction of the bar 1 and the outer diameter upper limit dimension inspection unit 13 is upstream in the conveyance direction. It is the structure arranged so that

このうち、曲がり検査部12は、図1に示すものは、棒材1の曲がり検査のための許容値を加味した内径を有する、例えば長さの短い3個のスリーブ12a〜12cを、所定の間隔を存して第1のハウジング12d内に、それぞれの軸中心が同一線上に位置するように固定した構成である。   Among these, the bending inspection unit 12 shown in FIG. 1 has, for example, three sleeves 12a to 12c having a short inner diameter, which have an inner diameter taking into account an allowable value for bending inspection of the rod 1. The first housing 12d is fixed so that the center of each axis is located on the same line.

このように、棒材1の曲がり検査のためのスリーブを棒材1の長手方向に複数に分割した場合には、棒材1がスリーブ12a又は12b又は12cに詰まった場合、第1のハウジング12dを取り外せば、容易に棒材1をスリーブ12a,12bおよび12cから取り外すことができる。この際、第1のハウジング12dをスリーブ12a,12bおよび12cの軸中心に沿った断面が形成するように分割しておけば、前記取り外しがより容易に行えるようになる。   As described above, when the sleeve for bending inspection of the bar 1 is divided into a plurality of parts in the longitudinal direction of the bar 1, when the bar 1 is clogged into the sleeve 12a, 12b or 12c, the first housing 12d. Can be easily removed from the sleeves 12a, 12b and 12c. At this time, if the first housing 12d is divided so as to form a cross section along the axial center of the sleeves 12a, 12b and 12c, the removal can be performed more easily.

一方、図2に示すものは、第1のハウジング12d内に、棒材1の曲がり検査のための許容値を加味した内径を有する、図1のスリーブ12a〜12cよりも長さの長い1個のスリーブ12eを固定した構成であり、この図2の例では、スリーブ12eは、その軸中心に沿った断面が形成するように2分割し、位置決めピン12eaで一体にするようにしている。   On the other hand, what is shown in FIG. 2 is one longer in length than the sleeves 12a to 12c in FIG. 1, which has an inner diameter taking into account a tolerance value for bending inspection of the bar 1 in the first housing 12d. The sleeve 12e is fixed, and in the example shown in FIG. 2, the sleeve 12e is divided into two parts so that a cross section along the center of the axis is formed, and is integrated with a positioning pin 12ea.

このようにスリーブ12eをその軸中心に沿った断面が形成するように分割可能な構成にすれば、スリーブ12eの長さが長い場合も、棒材1がスリーブ12eに詰まった場合の処理が容易に行える。   If the sleeve 12e is configured to be split so that a cross-section along the axial center is formed in this way, even when the sleeve 12e is long, the processing when the rod 1 is clogged with the sleeve 12e is easy. Can be done.

なお、曲がり検査のための許容値を加味した内径とは、棒材1の外径によっても変化するが、例えば製品の外径許容値+0.8〜1.0mm程度である。   In addition, although the internal diameter which considered the allowable value for a bending test | inspection changes also with the outer diameter of the bar 1, it is about the outer diameter allowable value + 0.8-1.0mm of a product, for example.

また、外径上限寸法検査部13は、図1に示すものは、前記曲がり検査のための許容値よりも小さい、外径検査のための許容値を加味した内径を有する1個の円筒ゲージ13aを、第2のハウジング13b内に固定した構成である。   Further, the outer diameter upper limit dimension inspection unit 13 shown in FIG. 1 has one cylindrical gauge 13a having an inner diameter that is smaller than the allowable value for the bending inspection and takes into account the allowable value for the outer diameter inspection. Is fixed in the second housing 13b.

一方、図2に示すものは、前記曲がり検査のための許容値より小さい、外径検査のための許容値を加味した内径を有するとともに、前記スリーブ12eよりも長さの短い1個の円筒ゲージ13cを、第2のハウジング13b内に固定した構成である。   On the other hand, what is shown in FIG. 2 has one cylindrical gauge having an inner diameter that is smaller than the allowable value for the bending inspection and taking into account the allowable value for the outer diameter inspection, and is shorter than the sleeve 12e. 13c is fixed in the second housing 13b.

なお、曲がり検査のための許容値より小さい外径検査のための許容値を加味した内径とは、例えば先に説明した例では、内径を小さくした円筒バイトの当該内径で、棒材1の外径によっても変化するが、例えば製品の外径許容値+0.2〜0.4mm程度である。   It should be noted that the inner diameter including the allowable value for the outer diameter inspection smaller than the allowable value for the bending inspection is, for example, the inner diameter of the cylindrical cutting tool having a smaller inner diameter in the example described above, and the outside of the bar 1 For example, the outer diameter allowable value of the product is about +0.2 to 0.4 mm, although it varies depending on the diameter.

そして、本発明の棒材の検査装置11は、前記スリーブ12a〜12c又は12eの軸中心と前記円筒ゲージ13a又は13cの軸中心が同一線上にあるように設けている。   The bar inspection apparatus 11 according to the present invention is provided so that the axial center of the sleeves 12a to 12c or 12e and the axial center of the cylindrical gauge 13a or 13c are on the same line.

また、図1及び図2に示した例では、両検査部12,13の間にV字状の搬送ローラ14を配置し、これら両検査部12,13と搬送ローラ14を、シリンダ12f,13d,15によって昇降可能に構成し、棒材1の径が異なる場合に対応できるものを示している。   Further, in the example shown in FIGS. 1 and 2, a V-shaped transport roller 14 is disposed between the inspection units 12 and 13, and the inspection units 12 and 13 and the transport roller 14 are connected to the cylinders 12f and 13d. , 15 are configured to be movable up and down, and can cope with a case where the diameter of the bar 1 is different.

以上の本発明の棒材の検査装置11によれば、横断面形状、すなわち外径の上限寸法を保証するための検査と曲がり矯正後の曲がり検査を同時に行なうことができる。そして、仮に棒材1がスリーブ12a〜12c又は12eに詰まった場合も容易に処理することができる。   According to the bar inspection apparatus 11 of the present invention described above, it is possible to simultaneously perform the inspection for ensuring the cross-sectional shape, that is, the upper limit of the outer diameter, and the bending inspection after the bending correction. And even if the bar 1 is clogged in the sleeves 12a to 12c or 12e, it can be easily processed.

本発明は上記の例に限らず、各請求項に記載された技術的思想の範疇内で、適宜実施の形態を変更しても良い。   The present invention is not limited to the above examples, and the embodiments may be changed as appropriate within the scope of the technical idea described in each claim.

例えば、検査する棒材1の径が1種類であれば、図1や図2のように両検査部12,13と搬送ローラ14を、シリンダ12f,13d,15によって昇降可能に構成する必要はない。   For example, if the diameter of the bar 1 to be inspected is one kind, it is necessary to configure both the inspection parts 12 and 13 and the conveying roller 14 to be movable up and down by the cylinders 12f, 13d and 15 as shown in FIGS. Absent.

また、図1や図2の例では、前記スリーブ12a〜12c,12eや前記円筒ゲージ13a,13cは、入側と出側がラッパ状に拡がったものを示しているが、入側のみラッパ状に拡がったものとしてもよい。   In the examples of FIGS. 1 and 2, the sleeves 12a to 12c, 12e and the cylindrical gauges 13a, 13c are shown in a trumpet shape on the entrance side and the exit side. It may be expanded.
