(First embodiment)
1. Structure of wire rod cleaning tool In this embodiment, the present invention is applied to a wire rod cleaning tool 1 for wiping and cleaning the surface of a spring wire rod. As shown in FIG. 1, the wire rod cleaning tool 1 includes at least a ring member 3 and a holding member 5.

  The ring material 3 is a member made of an elastic material that can be elastically deformed, and is an annular member into which the wire 1A can be inserted. When the wire 1A is inserted into the ring material 3, the inner peripheral surface of the ring material 3 is in sliding contact with the outer peripheral surface of the wire 1A.

  The ring material 3 according to the present embodiment is an “O-ring (see JIS B 2401 etc.)” made of a rubber material such as nitrile rubber. In addition, since the wire 1A is in sliding contact with the inner peripheral surface of the ring material 3, it is desirable to use the “movement O-ring” rather than the “fixing O-ring”.

  The holding member 5 is a member that holds the ring material 3. The holding member 5 includes at least a first holding member 5A and a second holding member 5B. As shown in FIG. 2, the first holding member 5 </ b> A has a recess 5 </ b> C into which the ring material 3 is fitted.

  As shown in FIG. 1, the recess 5 </ b> C is a recessed portion that is recessed from the surface facing the second holding member 5 </ b> B in the first holding member 5 </ b> A, and is substantially the same as the outer diameter of the ring material 3. It is a cylindrical depression having a diameter.

  A disc-shaped flange 5D for locking the ring material 3 is provided at the bottom of the recess 5C. The flange portion 5D is provided with a through hole 5E (see FIG. 2) through which the wire 1A can pass.

  As shown in FIG. 1, the second holding member 5 </ b> B is a member that is detachably assembled to the first holding member 5 </ b> A. The second holding member 5B is provided with a convex portion 5F for pressing the ring material 3 fitted in the concave portion 5C against the flange portion 5D.

  As shown in FIG. 3A, the convex portion 5F is a cylindrical protrusion having a through hole 5G through which the wire 1A can pass. The outer diameter of the convex portion 5F is substantially the same as the hole diameter of the concave portion 5C. As shown in FIG. 3B, a conical tapered surface 5H that is continuous with the through hole 5G is provided on the surface of the second holding member 5B opposite to the convex portion 5F.

  As shown in FIG. 1, the second holding member 5B is assembled to the first holding member 5A by a mechanical fastener such as a hexagon socket head bolt 5J (hereinafter referred to as a bolt 5J). In the present embodiment, the first holding member 5A and the second holding member 5B are assembled with at least two bolts 5J.

  One of the two bolts 5J is disposed on one side with the convex portion 5F interposed therebetween, and the other bolt 5J is disposed on the other side with the convex portion 5F interposed therebetween. When the two bolts 5J are tightened, the pressing force with which the convex portion 5F presses the ring material 3 increases. That is, the two bolts 5J function as an adjustment unit for adjusting the pressing force by the convex portion 5F.

  As shown in FIG. 1, a scraper portion 7 having a through hole 7 </ b> A through which the wire 1 </ b> A can pass is provided on the front side of the holding member 5. The front side refers to the moving direction receding side (the right side in FIG. 1) of the moving wire 1A.

  Of the scraper portion 7, at least a portion constituting the inner peripheral surface of the through hole 7 </ b> A is made of the same material as the ring material 3 or harder than the ring material 3 (in this embodiment, a urethane sheet or a fluororubber sheet). The diameter of the through hole 7A is substantially the same as the diameter of the outer peripheral surface of the wire 1A, and is a dimension capable of sliding contact with the outer peripheral surface of the wire 1A.

  In the present embodiment, a washer 7B that supports the scraper unit 7 is disposed on the holding member 5 side of the scraper unit 7. The washer 7B is locked to the pair of bolts 5J or the second holding member 5B, thereby restricting the scraper portion 7 from moving together with the wire 1A to the first holding member 5A side (the left side in FIG. 1).

  An oiling device 9 is provided on the front side of the scraper unit 7. The lubricator 9 lubricates the outer peripheral surface of the wire 1A. Note that the oil to be lubricated is preferably an oil having a low viscosity, such as oil washing.

2. As shown in FIG. 1, when the wire 1 </ b> A moves relative to the wire cleaner 1 and the scraper part 7, the inner peripheral surface of the ring member 3 is in sliding contact with the outer peripheral surface of the wire 1 </ b> A. Thus, the surface of the wire 1 </ b> A is wiped off by the ring material 3.

  At this time, the ring material 3 fitted in the concave portion 5C is pressed against the first holding member 5A (flange portion 5D) by the convex portion 5F of the second holding member 5B, and is elastically deformed so as to be crushed by the pressing force. Therefore, since the contact surface pressure between the ring material 3 and the wire 1A can be increased, the surface of the wire 1A can be wiped off with a simple configuration.

  When the pair of bolts 5J are tightened, the pressing force that presses the ring material 3 increases, and the ring material 3 is largely crushed. Therefore, in this embodiment, even when the wear of the ring material 3 progresses and the contact surface pressure between the ring material 3 and the wire 1A decreases, the pair of bolts 5J are tightened to restore the contact surface pressure. Can be made.

  In this embodiment, since the scraper part 7 is provided on the front side of the holding part 3B, powdery foreign matters such as metal powder attached to the surface of the wire 1A can be removed by the scraper part 7.

  Therefore, since the wire 1A from which the powdery foreign matter has been removed is supplied to the ring material 3, it is possible to suppress the wear and damage of the ring material 3 from proceeding at an early stage. As a result, the durability of the ring material 3 can be improved.

  Since the oil feeder 9 for injecting oil is provided on the front surface side of the scraper unit 7, it is possible to alleviate the adhesion state of the foreign matter adhering to the wire rod 1A. Therefore, since the foreign material adhering to the wire 1A can be reliably removed by the scraper portion 7, the durability of the ring material 3 can be improved.
