本発明は鋼管、棒鋼等の疵検査及び疵研削を実施する装
置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for inspecting and grinding steel pipes, steel bars, etc. for flaws.

は極めて重要な課題である。BACKGROUND OF THE INVENTION In products with circular circumferential shapes, such as steel pipes or steel bars, defects occur due to the manufacturing process or materials, and manual grinding is performed to remove these defects. However, manual grinding is mostly done manually, and automating it is an extremely important issue in order to streamline the manufacturing process and deal with the deterioration of the working environment due to the generation of grinding dust.
現在実用化されている疵検査、研削装置の自動化の例を
第４図及び第５図に示す。Examples of automated flaw inspection and grinding equipment that are currently in practical use are shown in FIGS. 4 and 5.
第４図はオンライン装置の例であり、被検査材４０が図

搬送ライン上に配置されている。FIG. 4 shows an example of an online device, in which a material to be inspected 40 is conveyed spirally in the direction of the arrow in the figure, and a flaw inspection device 41 is installed on the upstream side of the conveyance direction, and a grinding device 42 is installed on the downstream side of the same conveyance line. placed above.

る。The flaw inspection device 41 sends a detection signal having information on the presence or absence of a flaw and its depth to the control device 43, and the control device 43 identifies the position of the flaw from the detection signal No. 1 and the conveyance position of the inspected material 40. , Grinding is performed directly below the grinding device 42 based on the identification results and the depth of the flaw. The conveyance speed of the inspected material is controlled, and for example, in the case of deep flaws, the conveyance speed during grinding is slowed down, and then the inspected material is returned to the conveyance start position, and the inspected material is conveyed again and the flaws are detected. If it is not detected, the grinding is terminated, and if it is detected, the grinding is performed again.

置５２によってマークを検出し、疵の研削を行うもので
ある。FIG. 5 shows an example of an off-line device, in which a material to be inspected 50 is conveyed in a spiral manner as in the case of FIG. The marks are detected by a plurality of mark detectors 54 and grinding devices 52 arranged on the downstream side in the conveyance direction, and the flaws are ground.
ところで円筒又は円柱材の大部分は素材から圧延工程に
よって軸方向に延ばされるものが一般的であるため、発
生する疵は軸方向に長いものが多く、また疵深さにはバ
ラツキがある。Incidentally, most of the cylinders or cylindrical materials are generally made from raw material and stretched in the axial direction by a rolling process, and therefore, many of the defects that occur are long in the axial direction, and the depth of the defects varies.
前述の自動研削装置では軸方向に長い疵に能率的に対応

深い部分に対応して研削を行うと、砥石幅の軸方向の長
さ分だけ同じ深さに研削されるため非能率的であり、ま
た研削開始及び終了部に段が形成される。The above-mentioned automatic grinding equipment uses a wide grindstone that is long in the axial direction in order to efficiently deal with long flaws in the axial direction and to prevent the occurrence of flaws that are not ground due to spiral conveyance. Since the width of the grinding wheel is wide, if you grind the deepest part of the flaw, it will be inefficient because it will grind to the same depth by the length of the grinding wheel width in the axial direction. steps are formed.
そして疵が検出されなくなる迄、探傷、研削を繰り返す
ことによって疵の深さに対応しているため、作業能率が
悪いという問題もある。Furthermore, since the depth of the flaw is dealt with by repeating flaw detection and grinding until the flaw is no longer detected, there is also the problem of poor work efficiency.
加えて第５図のオフライン装置では疵検査装置のマーキ
ング精度及び研削装置のマーク検出精度に問題があり、
また、マーキング後の搬送途中でマークが消失し、研削
が行われないこともある。In addition, the offline device shown in Figure 5 has problems with the marking accuracy of the flaw inspection device and the mark detection accuracy of the grinding device.
Further, the mark may disappear during transportation after marking, and grinding may not be performed.
そして研削装置を複数台配置でき研削能率が良い反面、
それに伴ってコスト高になるという欠点がある。While multiple grinding devices can be installed and grinding efficiency is good,
This has the drawback of increasing costs.

The material to be inspected is moved in the axial direction based on the detection results of

Therefore, by controlling the grinding pressure by the operating amount of the hydraulic cylinder 2 while keeping the load current constant, grinding is performed according to the depth of the flaw.
