Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an apparatus suitable for simultaneously dayscaling two wire rods by shot blasting.

(Prior art) In recent years, from the perspective of improving productivity, it has been proposed to shot blast multiple wire rods at the same time. There were problems such as the initial penetration of multiple wire rods into the cleaning chamber required a large amount of time and process, and a special jig.

(Purpose of the invention) This invention was made in view of the above circumstances.
When the two wire rods are initially penetrated one by one into the cleaning chamber, the second wire rod to be initially penetrated is moved to a position separated from the first wire rod that has already been initially penetrated, while being used as a shot blast. It is an object of the present invention to provide a shot blasting device in which two wire rods sometimes penetrating a cleaning chamber can be brought close to each other.

(Structure of the invention) Hereinafter, the structure of the invention will be explained in detail based on the drawings of the embodiment.As shown in FIG.

It is constructed as shown in FIG. 3, which is the right side of FIG. 2. That is, as shown in FIG. 2, two brackets 5, 5 are fixed to the top position of the left outer surface of the box-shaped support member 4 at a predetermined distance in the front-rear direction relative to the plane of the paper. , 5, two guide rollers 6, 6, which guide the wire W in the direction of the arrow while sandwiching it, are pivoted at a required interval in the vertical direction, and each guide roller 6 is attached to the outer peripheral surface. , two grooves each having a semicircular cross section and a radius larger than the radius of the thickness of the wire W are provided. Furthermore, two support plates 7, 7 are fixed to the inside of the support member 4 at a required interval in the front-rear direction with respect to the plane of the paper, and the support plate 7 on the front side (the left side in FIG. 3) has the following features: While supporting the wire rod W,
A guide roller 8 that guides the lower side of the groove 11 of the grooved roller 12, which will be described later, is pivoted so that the conveyance level is a required height higher than the conveyance level of the lower one of the guide rollers 6, 6. . Further, a link 9 is attached to a position above the guide roller 8 on the support plates 7, 7 and is supported at the base so as to be movable up and down. The grooved roller 12 has grooved rollers 12 on its outer circumferential surface.
It is provided with a groove 11 having a semicircular cross section and a radius larger than the radius of the thickness of the wire W (see FIG. 3).

It is pivotally supported by a plate 14 via a pair of bearing units 15, 15, and the grooved roller 12 and the like are configured to pivot up and down via a link 9 as a cylinder 13 expands and contracts. Further, as shown in FIG. 3, a link 9, a grooved roller 12, a cylinder 1
No. 3, etc. are provided on the left and right (front and back with respect to the plane of the paper in FIG. 2), and there are two each, and the grooved rollers 12, 12
It is located inside 3.13. Further, these links 9, 9, grooved rollers 12, 12, cylinders 13, 13, etc. are arranged at an angle of approximately 30 degrees clockwise with respect to the vertical plane containing the wire W (in FIG. 2, the upper side of these is (approximately 30 degrees backwards). Furthermore, the two links 9, 9, the grooved rollers 12, 12, the cylinders 13, 13, etc. are each shifted by a required distance diagonally up and down, and are shifted from each other in the left and right direction (in FIG. They are separated by a required distance (in the front-back direction with respect to the plane of the paper). In addition, in FIG. 2, the link 9, the grooved roller 12, the cylinder 13, etc. at the rear with respect to the page are omitted.

The guide roller mechanism 2' disposed on the right side of the cabinet 1 in FIG. 1 has exactly the same structure and function as the guide roller mechanism 2 disposed on the left side of the cabinet 1 described above, The guide roller mechanism 2 is in a mutually symmetrical relationship with the cabinet 1 as the center of symmetry.

(Operation of the device) Next, the operation of the device configured as described above will be explained. First, the first wire W to be processed
is inserted between the rear grooves of the guide rollers 6, 6 of the guide roller mechanism 2 located on the left side in FIG. ) grooved roller 1
2 into the upper side of the groove 11, and then the wire W is further moved in the direction of the arrow to penetrate the cabinet 1 from left to right. Then,
The wire W coming out of the cabinet 1 is engaged with the upper side of the groove 11 of the grooved roller 12' which is mutually symmetrical to the left grooved roller 12 with which the wire W engages in the right guide roller mechanism 2'. Subsequently, the wire W is further moved and placed between the rear grooves of the guide rollers 6', 6' of the right guide roller mechanism 2', and then taken out. Next, the piston rods 13a, 13a' of the cylinders 13, 13' associated with the grooved rollers 12, 12' engaged with the wire W are extended, and the grooved rollers 12, 12' are moved through the links 9, 9'. The wire rod W is raised diagonally upward, thereby moving the wire rod W diagonally upward and temporarily moving the wire rod W out of the shot projection area formed by the shot projected from the shot projection device. Next, the cylinder 1 on the front side (left side in FIG. 3) of the left guide roller mechanism 2 and the right guide roller mechanism 2'
By contracting the piston rods 13a and 13a' of 3 and 13', the grooved rollers 1 on the left front side and the right front side
2 and 12' are lowered diagonally downward, and the line connecting the lower sides of these grooved rollers 12 and 12' is moved outside the shot projection area mentioned above.
Rear grooved roller 1 on which the wire rod W is stretched
2 and 12' between the upper sides of the grooves 11 and 11', and the grooved roller 1 on the front side on which the wire rod W is subsequently stretched.
2, 12' and the lower side of the grooves 11, 11', and then the front grooved roller 1
2, 12', the tip of the wire W that is stretched between the lower sides of the grooves 11, 11' has already touched the grooves 11, 1 in the grooved rollers 12, 12' on the rear side during movement.
1' so as not to wrap around the wire W that is stretched between the upper sides of the wires. Next, the second wire W to be processed is moved in the direction of the arrow while being guided and supported by the left guide rollers 6, 6, etc. and the guide roller 8, and then moved by the grooved rollers on the rear side mentioned above. 12, 12', the grooved rollers 12, 1 on the front side (left side in FIG. 3)
The second wire W is engaged and stretched between the lower sides of 2'. Thereafter, the piston rods 13a, 13a' of the rear cylinders 13, 13' are contracted, and the piston rods 13a, 13a' of the front cylinders 13, 13' are expanded, and the grooved rollers 12, 12' of the rear side are expanded. The distances between the upper sides of the grooves 11, 11' and the lower sides of the grooves 11, 11' of the front grooved rollers 12, 12' are made closer to each other, as shown in FIG. 3, and the two wire rods are Move W and W into the shot projection area. As mentioned above, the rear grooved roller 1
By passing the wire W between the grooves 11 and 11' of the rollers 2 and 12' on the upper side and between the grooves 11 and 11' of the front grooved rollers 12 and 12' on the lower side, Even though the vertical distance between the rear grooved rollers 12, 12' and the front grooved rollers 12, 12' is short, when the wire W is initially penetrated, 2
The main wire rods W, W can be largely separated from each other, and when the two wire rods W, W are shot blasted, the two wire rods W, W can be brought very close to each other. (See Figure 3). In addition, as shown in FIG. 3, two wire rods W,
The Ws are arranged in a tilted manner rotated approximately 45 degrees clockwise with respect to the horizontal plane, so that they do not interfere with each other when receiving shots projected from the vertical and longitudinal directions. In this state, by projecting a shot while moving the two wire rods W, W in the direction of the arrow, the two wire rods W, W can be simultaneously shot blasted.

In the above embodiment, the link 9, the grooved roller 12, the cylinder 13, etc. are provided in a state where they are rotated clockwise in FIG. 3, but they are provided in a state where they are rotated in a counterclockwise direction. Of course, similar effects can be obtained.

(Effects of the invention) As is clear from the above explanation, the present invention provides two grooved rollers each on the wire rod inlet side and the wire rod outlet side of the cabinet constituting the cleaning room, with the cabinet as the center of symmetry. Because they are arranged so that they are symmetrical and can be raised and lowered diagonally,
When the wire rod is initially penetrated into the cabinet, the second wire rod can be moved at a position largely separated from the existing first wire rod, so that the second wire rod to be initially penetrated is separated from the existing first wire rod. 1
This makes it possible to prevent the phenomenon of winding around the second wire. In addition, by raising and lowering the grooved roller diagonally, the wire rod can be removed from the shot projection area as appropriate, so if you want to stop transporting one wire rod and interrupt the shot blasting of that wire rod, you can remove the wire rod from the shot projection area. This has excellent practical effects, such as being able to raise or lower the wire in an oblique direction and remove it from the shot projection area, while continuing shot blasting of other wires.
