本発明は、連続する長尺線材の表面疵を除去す
るに当り、疵部分のみを的確にかつ自動的に切削
除去するための新しい手段の提供に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the provision of a new means for accurately and automatically cutting off only the flawed portion when removing surface flaws from a continuous long wire.
ベアリング鋼、ステンレス鋼、弁バネ鋼等の素
材による高級線材は、その表面に生じる欠陥即ち
各種の疵を除去しなければならないが、現行の表
面疵の除去手段は、線材の全周、全長に亘る表面
切削によつて疵部分を同時に除去する仕組であ
る。このような切削手段では材料歩留りが90％程
度に低下し、当然に製造コストのアツプを招くこ
とが大きな問題点である。 High-grade wire rods made of materials such as bearing steel, stainless steel, and valve spring steel must have defects or various scratches that occur on their surfaces removed, but current methods for removing surface flaws only cover the entire circumference and length of the wire rods. This mechanism simultaneously removes the flawed portion by cutting the surface over the entire surface. A major problem with such cutting means is that the material yield drops to about 90%, which naturally leads to an increase in manufacturing costs.

13φの細径線材のものに対しては生産性が悪くま
た、ドローイング方式においては処理速度は充分
であるが、全面全長に亘る表面皮削りのため、歩
留りの悪いという点で、それぞれ欠点がある。 Currently, the methods for removing surface flaws in this type of wire include a drawing method to scrape the entire surface over the entire length, and a peeling method combined with automatic control, which is mainly used for large diameter wires of 13φ or more. A method for removing partial defects on the entire surface has been put into practical use and has achieved good results, but the processing speed of the peeling method is 15 m/min.
At low speeds below min, the most demanded 5.5φ~
The productivity is poor for 13φ thin wire rods, and although the drawing method has sufficient processing speed, it has its drawbacks in that the yield is poor because the surface is scraped over the entire length. .

ようにした点にある。 The present invention has been made in order to improve the yield without reducing productivity when removing surface flaws from such wire rods. The flaw detection device detects the flaw position in the longitudinal direction and circumferential direction of the wire, and the wire passes through the center hole of the wire, which has a cutting surface with a diameter equal to or larger than the outer diameter of the wire. The present invention is characterized in that the peeling die is moved toward the flaw to cut and remove only that part.

充分にカバーすることができる。 The present invention will be described in detail below based on the illustrated embodiments. Fig. 1 is a line diagram of a flaw removing device using the method of the present invention, and Fig. 2 shows an embodiment of an automatic means for removing only the flaw portion. , FIG. 3 shows an explanatory diagram of distribution of the same flaw setting position, and FIG. 4 shows a cutting state diagram of the same flaw part. In FIG. 1, the wire rod 2 from the supply stand 1 is straightened. It is straightened by passing through a group of rollers 3, and passed through an automatic flaw detector 4 to detect the site where a surface flaw has occurred. The wire rod is sent to the automatic partial cutting machine 6 according to the invention, and as described later in the same cutting machine 6, only the target flawed part is automatically cut off, and the uncut wire rod is sequentially wound up on the winding machine 7 side. Since the automatic flaw detector 4 and the flaw position command device 5 are both conventionally known devices, their details will be omitted. The automatic partial cutting machine 6, which is a device for carrying out the method of automatically cutting only the flawed portion of the wire rod 2 according to the present invention, has the configuration illustrated in FIG. 2. That is, in FIG. 2, reference numeral 8 is a peeling die, and the die 8 is used to cut the wire 2, which is made to advance linearly in the direction of the arrow X, through an inlet die 9 and an outlet guide 10, into a concentric center hole. 8a, and a cutting surface 8b having a diameter equal to or larger than the outer diameter of the wire rod 2 is formed on the entrance side of the center hole 8a, and the peeling die 8 is a substantially disc concentric with the die 8. The housing 11 is installed and supported in the center hole 11a of the housing 11 at the center of the shaped housing 11, and the housing 11 is arranged at three symmetrical points at six equal parts of the circumference surrounding the center and the center of the passing wire 2. and three retaining bolts 13 each slidably supported by a compression coil spring 12.
14 indicates a holder for each bolt 13. Furthermore, in the illustrated example, three hydraulic cylinders 15 are provided as drive parts for selectively tilting the peeling die 8, occupying three symmetrical points equally divided into six positions on the circumference in the middle of these support bolts 13. The tip of the piston rod 15a of each cylinder 15 is movably connected to the back surface of the housing 11, and each of these hydraulic cylinders 15 is controlled by an electric signal from the flaw position command device 5 mentioned above. Therefore, the electromagnetic switching valve 16 and the hydraulic circuit 17 are used to selectively operate the valves alone or in combination. The entire device including these members is housed in one casing 18 as a unit. That is, as shown in FIG. 3 showing the installation positions of these support bolts 13 and hydraulic cylinders 15, in the present invention, the flaw setting positions are divided into six equal parts of the circumference of an arbitrary radius centered on the center of the wire rod 2.
Place three holding bolts 13 like 13-1, 13-2, and 13-3 at the symmetrical three point positions, and then place three symmetrical bolts 13 at the midpoints of each of these bolts 13-1 to 13-3. Three hydraulic cylinders 15-1, 15-2, and 15-3 are arranged occupying point positions, thereby making these six points of action,
Covering the entire circumference of the wire 2, no matter where on the circumferential surface there is a surface flaw, it is detected by the automatic flaw detector 4, the flaw position command device 5 is activated, and the electromagnetic switching valve is activated. Hydraulic cylinders 15-1 to 15-1 are selectively operated according to the position of the surface flaw.
5-3 is selected and activated, cylinders 15-1 to 15
-3, by advancing each piston rod 15a and tilting the housing 11 at one of the six points of action, and simultaneously tilting the peeling die 8 to remove only the surface flaws. is automatically cut and removed as the wire rod 2 advances. At this time, if each of the hydraulic cylinders 15-1 to 15-3 and the flaw are at the same position among the six points of action shown in the diagram, only one of the relevant cylinders will be operated and the center will be centered at the holding bolt 13 position. In the case of the intermediate position, the two hydraulic cylinders 15 on both sides of the flaw position are driven in cooperation, for example, 15-1 and 15-2, and in this way, 6 hydraulic cylinders 15 are driven. By arranging the points of action P, surface flaws located at any position can be sufficiently covered over the entire circumference of the wire 2.

つてゆくのである。 Therefore, according to the partial cutting means of the present invention shown in FIGS. 2 and 3, as shown in FIG. The position of the surface flaw is detected and the position of the surface flaw is issued as an electric signal by the flaw position command device 5, which prompts one or two hydraulic cylinders 15 to be driven according to the position, thereby causing the rod 15a of the cylinder 15 to be driven. Due to the advancement of housing 1
The target point of action P among the six points of action 1 is a point P that is equally divided and symmetrical to this point, which is also P in the illustration.
Therefore, to avoid confusion, it is indicated as point O, and the point is tilted <θ° with this point O as a fulcrum. Therefore, the cutting surface 8b of the peeling die 8 located at the center of the housing 11 also moves from the Q point position to R.
It is tilted as shown in the point position, and only the surface flaws specified under the cutting depth A are cut and removed. When the cutting is completed, the compression coil spring 12 in the holding bolt 13 returns to its original state, and the housing 11 returns to its original state, removing the skin. The peeling die 8 also returns to its original state, and the cutting surface 8b separates from the circumferential surface of the wire 2. In this way, regardless of the surface flaw located at any position on the wire rod 2, the peeling die 8 is automatically tilted toward the circumferential surface where the surface flaw exists.
This ensures complete automatic cutting of only the flawed portion. FIG. 4 shows the cut cross-sectional shape of only the flawed part. In the example shown, r is the outer diameter of the wire rod 2, R is the diameter at the cutting surface 8b of the peeling die 8, and a is the diameter of both. indicates clearance,
In addition, A indicates the circumference of the cutting surface when the peeling die 8 is not tilted, and B indicates the circumference of the cutting surface when the peeling die 8 is tilted, as shown in the figure. The inclined part C of the shape indicates the entire cutting range when the dashis is tilted, and at any point of action P, the cutting depth is the deepest at the point of action,
It gradually becomes shallower as it moves away from the point of action on both sides.

である。 5 and 6 show an embodiment of the automatic cutting means for only the flawed portion of the present invention, which is different from FIGS. The wire rod 2 is moved toward the flaw on a plane orthogonal to the wire rod 2, and only the flawed portion of the wire rod 2 is automatically cut. In order to accomplish the above, the automatic partial cutting machine 6 is configured as follows. That is,
As shown in FIG.
The tips of each of the holding bolts 13 are formed into a spindle-shaped holding part 20. Then, the holding part 20 is slidably engaged in an engaging part 21 formed correspondingly to the housing 11, and the housing 11 is attached to the holder 14.
The rear surface of the housing 11 is attached to the holder 1 so that the rear surface of the housing 11 is slidable on a surface perpendicular to the direction of movement of the wire rod 2.
4 It is in contact with the front. In addition, the housing 11
Three hydraulic cylinders 15 are arranged at equal intervals in the circumferential direction around the center of the wire 2 on the outside of the outer periphery. Then, the tip of the piston rod 15a of the hydraulic cylinder 15 is fixed to each retaining bolt 1 in the circumferential direction.
The outer circumferential surface of the housing 11, which is located radially outward of the center position between the wire rods 2 and 3, is connected to and supported on the outer circumferential surface of the housing 11 so as to be movable forward and backward with respect to the center of the wire rod 2. These hydraulic cylinders 15 are operated by electric signals from the flaw position command device 5 via an electromagnetic switching valve 16 and a hydraulic circuit 17. Note that the same reference numerals in FIG. 2, FIG. 5, and FIG. 6 other than those described above indicate members and portions having the same functions. According to this embodiment, the wire 2
No matter where a surface flaw exists on the entire circumference, the automatic flaw detector 4 detects it, activates the flaw position command device 5, operates the electromagnetic switching valve 16, and determines the position of the surface flaw. By operating each hydraulic cylinder 15 in accordance with the direction of movement of the wire rod 2 and sliding the housing 11 toward the flaw on a plane perpendicular to the direction of movement of the wire rod 2, the peeling die 8 that has moved together with the housing 11 removes the surface flaw. Only that portion is automatically cut and removed as the wire rod 2 passes through.

切削を受けないことになる。 According to the method of the present invention, as illustrated in the line diagram of FIG. The positions of flaws occurring in the longitudinal direction and circumferential direction of the wire rod 2 are detected, and the detected flaw positions actuate the hydraulic cylinder 15 in the automatic partial cutting machine 6 via the flaw position command device 5. As a result, the peeling die 8 is tilted or moved on the plane by tilting the housing 11 or sliding on the plane perpendicular to the traveling direction of the wire rod 2, and the cutting surface 8b of the peeling die 8 cuts the detected flaw. By being displaced toward the position, automatic cutting of only the flawed portion can be completely achieved, and areas other than the flawed portion will not be cut at all.
