Description of the Related Art Conventionally, as a means for removing flaws generated on the surface of a linear material such as a bearing steel or a stainless steel for cold heading, (A) a linear material is stretched over its entire length by a chipper die. (B) a means for peeling the linear material over the entire length thereof, visually inspecting the flaws, polishing only the flaws with a hand grinder or the like, and (C) refining the linear material. After marking the flaws with paint etc. on the flaw detection by the automatic flaw detector over the entire length,
There is a means for polishing and peeling the marking portion with a hand grinder or the like.

不利が生じていた。[0003] However, in the case of the means (A) and (B), peeling is performed to a portion having no flaws, which causes factors such as a decrease in product yield and an early consumption of the peeling tool, which increase costs. Is big. In addition, in the methods (C) and (D), only the necessary portions are peeled, which greatly improves the product yield. However, the linear material is unraveled, and the entire length and the entire circumference are visually inspected. For this reason, it is necessary to search the marking portion over the entire length and the entire circumference, so that the workability is extremely poor, which is not preferable in terms of efficiency, and there is a disadvantage that labor costs are greatly increased.

We have proposed a "line or rod-shaped surface flaw automatic cutting device" that automatically removes and removes flaws on linear materials with a flaw cutting device (flaw cutting device) on the same line.

時、切削されない疵がそのまま残る。Although the above problems can be solved by using the above-mentioned apparatus, there are the following problems to be solved in order to remove all harmful flaws. The cutting allowance in the automatic flaw cutting device is set so as to cut a predetermined depth with only one cutting tool in the same cross section of the linear material in order to prevent breakage of the cutting tool and disconnection during cutting. Therefore, when there are flaws deeper than the cutting allowance, uncut parts are generated. Further, when there are two or more flaws on the same circumference of the linear material, flaws that are not cut remain as they are.

（空巻状態）にしてある。When the linear material 1 is drawn straight from the coil cannon type supply stand 2 in a state as shown in the figure, the linear material 1 is rotated rightward in the axial direction 2a with respect to the axial direction. The wire 1 is twisted 360 degrees in one turn of the wire 1 in the right direction if it is wound and left if it is wound left. In order to solve this problem, the wire 1 is wound around the winding drum 3 in the reverse direction by about one turn. Moreover, the wound linear material 1
Is in a free state (empty winding state) without contacting the torsion eliminating winding drum 3.

ルを補充する必要がある。In this embodiment, since a horizontally disposed coil artillery type supply stand is used, the winding drum 3 for eliminating twisting is provided. However, the coil 2a is loaded on the vertically disposed drum, and the linear material 1 is loaded. This may be rotated together with the pull-out so that the linear material is pulled out without twisting. However, in this case, since the coil 2a is rotating, it is not possible to weld and continue the additional coil during operation. Therefore, when the coil is pulled out, it is necessary to stop the equipment and replenish the coil. .

い線状材１にする。In the flaw automatic cutting device line, in order to prevent bite breakage, disconnection at the time of cutting, etc., it is set so as to cut a predetermined depth with only one bite in the same cross section of the linear material 1. . Therefore, when there are flaws deeper than the cutting allowance, uncut parts are generated. When two or more flaws are present in the same cross section of the linear material 1, flaws that are not cut remain as they are. Then, the flaw detected by the flaw detector 4 is removed by the flaw cutting device 6, but when there is a flaw deeper than the cutting allowance and when there are two or more flaws in the same cross section, the die after flaw cutting is used. The linear material 1 is stopped at a point of a flaw inspection flaw removal place 10 between the wire 8 and the wire drawing drum 9 and flaw detection flaw removal is performed at this location to obtain a linear material 1 without harmful flaws.

When the above flaw is present, a signal indicating that such flaw is present is transmitted from the flaw detector 4 to the distance calculator 5.
When the detection flaw of the linear material 1 has moved the distance from the flaw detector 4 to the flaw detection flaw removing place 10, the winding device 11
Then, a stop signal is sent to the wire drawing machine, and in that state, flaw grinding is performed manually at the flaw inspection flaw removing place 10.
