Practical effect To.

Hereinafter, an embodiment of a wire shot blasting apparatus to which the wire rod anti-sway device of the present invention is applied will be described in detail with reference to FIGS. As shown in FIG. 5 and FIG. 6, the shot blasting apparatus includes a cabinet 1 that constitutes a polishing chamber, a carry-in port and a carry-out port for the wire W in the cabinet 1, and a required interval in the left-right direction in the cabinet 1. A plurality of guide members 3, 3 that are fixedly disposed and have tapered through holes 2, and are fixed to the guide member 3 at the center of the plurality of guide members 3, 3, The first anti-sway device 4 that holds the wire W extending through in the left-right direction, and 2 of the plurality of guide members 3, 3 fixed to the wire W entrance and the exit of the wire 1 of the cabinet 1, respectively. A pair of second anti-sway devices 5 and 5, four centrifugal projection impellers 6 and 6 that project a projection material toward the wire W that penetrates the cabinet 1, and a wire that penetrates the cabinet 1 W are constituted out with pulling means for pulling the wire W from left to right while applying a tension of predetermined magnitude (not shown).

As shown in FIG. 1, the first anti-sway device 4 is elastically supported toward substantially the center of the wire rod W in a stretched state and is rotatable in any direction, and the material is a special alloy steel, Four substantially spherical support members 7 and 7 having a diameter of 4 to 25 mm and a hardness of HV400 to 1400, and a support member 7 and 7 provided via a raising member 8 are connected to the wire W. Plate springs 9 and 9 as elastic support means elastically supporting substantially toward the center, and support means including the four support members 7 and 7 and the four plate springs 9 and 9 as interiors. And a horizontal box-shaped covered box body 10, and in the first anti-sway device 4, as shown in FIG. 2, a support member composed of the four support members 7, 7. 3 groups of groups 7A and 7A are connected in the extending direction of the wire W in a stretched state. , One of the leaf spring 9 is made to the three sets of one each of the support members 7 in the support member group 7A-7A, ie to simultaneously elastically supporting the three support members 7, 7. When the wire W penetrates between the four support members 7 and 7, the four support members 7 and 7 and the four leaf springs 9 and 9 are in the state shown in FIG. The four support members 7 and 7 are configured to press the wire W toward the center thereof.

The left and right side walls of the lidded box body 10 have two openings 11 and 11 through which the wire W can penetrate substantially the center position of the space defined by the four support members 7 and 7. Further, a discharge hole 12 for the projection material is provided on the lower side wall. A flange 13 is formed on the outer peripheral portion of the left side wall of the covered box body 10, and the covered box body 10 is attached to the guide member 3 via the flange 13.
Since the support member 7 has a diameter larger than that of the wire W, the support member 7 does not exit from the openings 11 and 11 of the covered box 10.

Further, the support member 7 in the second anti-sway device 5 is also a support member group 7A composed of four support members 7 and 7 for sandwiching the wire W, similarly to the first anti-sway device 4 shown in FIG. 7A is provided in a triple manner in the left-right direction, which is the direction in which the wire W extends, and the second-stage support member group 7A has one support member 7 in the first or third stage. It is structured such that the wire W is rotated at a required angle around the wire W so as to be positioned approximately between the two support members 7 and 7 in the group 7A, and holds and projects the wire W. The material can be prevented from jumping out of the cabinet 1.
From the viewpoint of production, the raising member 8, the leaf spring 9, and the covered box body 10 are each divided into three in the direction in which the wire W extends.

The four impellers 6 and 6 are provided at a necessary interval in the direction in which the wire W extends, and project the projection material from the front / rear direction and the up / down direction to the wire W. It is like that. The projecting material projected from the four impellers 6 and 6 is collected by a screw conveyor 14 and a bucket elevator 15 mounted on the bottom of the cabinet, and then impurities are removed by a conventional separation device (not shown). After that, they are again supplied to the four impellers 6 and 6, respectively.

As shown in FIG. 7, the structure configured as described above includes a wire rod W to be scoured, a second anti-sway device 5 on the wire carrying-in side, a plurality of guide members 3 and 3, a first anti-sway device 4 and a wire material After passing the second anti-sway device 5 on the carry-out side, the wire W is pulled and moved while tension is applied to the wire W. The wire W is guided by the tapered through hole 2 in the guide member 3 and then inserted between the spherical support members 7 and 7 so as to penetrate the second anti-sway device 5 and the first anti-sway device 4. Therefore, the penetration work of this wire W can be performed easily.

In this manner, the projecting material is projected onto the wire W by the impellers 6 and 6 while the wire W penetrating the second anti-sway device 5 and the first anti-sway device 4 is pulled and moved. As a result, the wire W tends to sway due to the projection of the projecting material. In particular, the two second anti-sway devices 5 and 5 and the first anti-sway device 4 are pressed by deformation of the leaf springs 9 and 9. The supporting members 7 and 7 that have received the pressure sandwich the wire W, and accordingly, the wire W is suppressed or prevented from being shaken. Further, since the wire W and the support members 7 and 7 are in so-called point contact and the support members 7 and 7 are rotatable, the projection material enters between the wire W and the support members 7 and 7. Even if it enters temporarily, it is discharged immediately. Therefore, the wire is not damaged. Then, the projection material that has entered the respective covered box bodies 10 of the first anti-sway device 4 and the second wire anti-sway device 5 is discharged from the discharge hole 12.

  Since the support members 7 and 7 are substantially spherical and elastically supported and rotatable, the projection material that has entered between the support members 7 and 7 and the wire W is placed on the surface of the wire W. Even if the wire W is bent locally and enters the first anti-sway device 4 in a stretched state without causing any damage, the first anti-sway device 4 causes resistance. The wire W can easily pass through the first anti-sway device 4 without increasing or being damaged.

For example, a steel wire W having a diameter of 7.5 mm is fed with a tension of 50 to 70 kg at a feeding speed of 60 m / min, and a shot having a particle diameter of 0.3 mm is applied to the wire W. When the projection is performed at a projection speed of 65 m / sec and compared with the case where the first anti-sway device 4 and the second anti-sway device 5 and 5 are not provided, the first anti-sway device 4 and the second anti-sway device 5 and 5 are used. In the case of the presence of the first anti-sway device 4 and the second anti-sway device 5 · 5, the diameter of the wire W was 7.5 mm + 25 mm.

Further, when there is the first anti-sway device 4 and the second anti-sway devices 5 and 5, the wire W does not come into contact with the inner surface of the through hole 2 of the guide member 3, so that the wire W is scratched. In the absence of the first anti-sway device 4 and the second anti-sway devices 5 and 5, the wire W often comes into contact with the inner surface of the through hole 2, so that the wire W is placed on the entire outer peripheral surface. A lot of scratches and dents were generated.
