Abstract

PURPOSE:To improve polishing capacity and workability by arranging a polishing ribbon capable of moving between the guides provided at the tips of a pressurizing and a separating means and an edge surface of a metallic flat wire. CONSTITUTION:A guide roller 1 supporting one edge surface is arranged on a base T on which a metallic flat line W runs while a polishing ribbon 2 is arranged on the other edge surface in the axial direction. Reels 3,4 are provided on both ends of the polishing ribbon 2 and a lower speed motor 5 is prepared as a mobile means on a reel side 4 to coil the polishing ribbon 2. And, on the side of the polishing ribbon 2 is arranged a micro cylinder 6 having at air piping as a pressurizing means and a pressurizing guide roller 7 having a groove similar to an edge surface shape is set freely rotatably to an axis on the bracket fixed to the tip of the rod 6a of the cylinder. Accordingly, the edge surface of the metallic flat wire W can be pressurized by the polishing ribbon 2 with a fixed force and polished, the abutting surface with the polishing ribbon 2 can be moved, no reduction of polishing capacity and no polishing nonuniformity are generated by clogging and continuous polishing excellent in precision can be performed to the edge surface.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for polishing the edge surface of a flat metal wire used for piston rings, spiral springs, etc.

[Conventional technology]

As shown in Fig. #I3, this type of conventional polishing device uses a square grinding wheel (9) (9) on the base of the running metal wire W with springs α and αΦ to polish both edge surfaces of the flat metal wire. They were placed facing each other so that they were in constant pressure contact.

[Problem to be solved by the invention]

However, in the conventional technology described above, the grinding wheel is constantly in pressure contact with both edge surfaces of the flat metal wire, so if the grooves become deeper due to wear, they become clogged, which not only significantly reduces the polishing ability but also causes uneven polishing. Ta. Therefore, it was necessary to frequently replace the grindstone with a new one, which inevitably led to a decrease in work efficiency.

SUMMARY OF THE INVENTION An object of the present invention has been made in view of the above-mentioned problems of the prior art, and is to provide an apparatus for polishing the edge surface of a flat metal wire with improved polishing force and workability.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a guide at the tip of a pressing/separating means that can move forward and backward with respect to the edge surface of a running flat metal wire, and between the guide and the edge surface, the flat metal wire An abrasive ribbon movable in the longitudinal or orthogonal direction is disposed.

Further, the pressing/separating means and the polishing ribbon moving means are connected to a control device using a timer.

[Effect]

With the above configuration, the edge surface of the running flat metal wire is polished by a part of the polishing ribbon pressed against the guide. When polishing the edge surface by disposing the polishing ribbon in the longitudinal direction of the flat metal wire, while the polishing ribbon is in pressure contact with the edge surface of the flat metal wire, move the polishing ribbon so that it faces the running direction of the flat metal wire using a moving means. and move slowly.

In addition, when polishing the edge surface by placing the polishing ribbon perpendicular to the flat metal wire, when the edge surface is polished for a predetermined period of time, the pressure contact/release means is activated by the timer, and as the guide retreats, the polishing ribbon is moved by the moving means. Move intermittently along its length. Then, the pressing/separating means works again, and the guide moves forward to press the polishing ribbon against the edge surface, thereby polishing the edge surface.

The above series of operations is repeated, and the edge surface of the flat metal wire is polished without being stopped for a long time.

Embodiments of the present invention will be described below with reference to the drawings.

[Example 1] In FIG. 1, on the platform (1) on which the flat metal wire W runs,
A guide roller (1) supporting one edge surface is provided, and a polishing ribbon (2) is provided in the axial direction on the other edge surface.

The polishing ribbon (2) has reels (3) (4) at both ends.
A low-speed motor (5) is provided as a moving means on the reel (4) for winding up the polishing ribbon. You can also use polishing ribbon (
On the 2) side, a micro cylinder (6) with air piping is installed as a pressure welding means, and a pressure guide roller with a groove close to the edge surface shape is attached to the bracket I fixed to the tip of the cylinder's rod ■. (7) is rotatably mounted on the shaft.

[Embodiment 2] Figure vg2 shows a different embodiment, in which a polishing ribbon (2) is disposed so as to be movable in a direction orthogonal to the flat metal wire (2).

A traveling flat metal wire W is supported by a guide roller (1) arranged on a part of the edge side of the table ■, and a micro cylinder (6 ), and a press-contact guide (8) with a groove similar to the shape of the edge surface is fixed to the tip of the rod of this cylinder, and this press-contact guide (8) is used to polish from a direction perpendicular to the wire axis. The ribbon (2) can be pressed and separated.

The polishing ribbon (2) has reels (3) (
4), and as in the first embodiment, a synchronized motor (5) for winding up the polishing ribbon is attached as a moving means to the reel (4) side.

Further, the micro cylinders (6) 8 and the synchronized motor (5) are connected to a timer-based control device so that the polishing ribbon is pressed against and separated from the edge surface and moved at required intervals.

By the way, the polishing ribbons and the like of Example 1.2 can be arranged so as to face each other on both sides of the flat metal wire, or can be arranged at different positions.

In this case, when a plurality of rods are arranged on the same edge surface, it is desirable to prevent the rods of the pressing/separating means from retreating at the same time.

〔Effect of the invention〕

Since the present invention has the above configuration, it is possible to press the polishing ribbon against the edge surface of the flat metal wire for polishing with a constant force, and the contact surface of the polishing ribbon can be moved continuously or intermittently, allowing large No reduction in polishing ability or uneven polishing due to clogging,
Continuous polishing of edge surfaces with high precision is possible.

In addition, since the polishing ribbon is visible, it easily adapts to the edge surface, and the polishing time can be shortened. Furthermore, since it is long, continuous polishing can be performed for a long period of time, which has the effect of greatly improving work efficiency.
