Description

[Detailed description of the invention] This invention is based on steel pipes and stainless steel pipes (cut to predetermined dimensions).
The present invention relates to a brush for deburring and polishing steel pipes, which has both deburring and polishing functions and can deburr and polish cut surfaces of steel pipes (hereinafter referred to as steel pipes).

Conventionally, a device for deburring the cut surface of a steel vibrator cut to a predetermined size is to place a steel vibrator 1 on a table 2 as shown in FIG. Generally, a structure is used in which deburring is carried out by bringing the tip of the deburring brush 3 into contact with the cut surface of the steel pipe 1 while rotating the deburring brush 3 on which wires are bundled. The wire diameter of the wire that constitutes the deburring brush 3 that is attached to the device and used is 0.5 mm.
Since the deburring brush 3 can be removed, it has the disadvantage that the cut surface becomes rough during deburring, and since the deburring brush 3 only rotates in a fixed direction, it does not come into contact with the cut surface of the steel pipe 1. Since only a portion of the tip of the deburring brush 3 is in contact with the brush 3, only the portion that comes in contact with the brush 3 is worn out, resulting in a short life span of the brush.

The present invention solves these drawbacks, and has both deburring and polishing functions, which can remove burrs from the cut surfaces of steel pipes cut to predetermined dimensions and evenly polish the cut surfaces. To provide a brush for deburring and polishing steel pipes, which has a long brush life.

More specifically, in the present invention, the wire diameter is within the range of 0.25 to 0.5 mm, and the average wire diameter is 0.3-0.4 ra.

It is also used for polishing.

The operation of deburring and polishing the cut surface of a steel pipe using the steel pipe deburring and polishing brush according to the present invention having such a structure will be described.

For example, as shown in FIG. 5, when three annular brush discs 12 are connected to the tips of three brush mounting shafts 16, the annular brush discs 12 rotate in the direction of the arrow by the drive device of the polishing device 10. Since the tip of the wire rod 4 is brought into uniform contact with the cut surface of the steel pipe, deburring and polishing can be performed.

The brush mounting shaft 16 is rotatably mounted on the rotary disk 11, and the second gear 16 is fixed to the brush mounting shaft 16.

1 rotates together with the sun shaft 13, so when the sun shaft 13 and the rotary disk 11 rotate to the left in the direction opposite to the direction of movement of the clock hands, as shown by the arrow in FIG. The brush mounting shaft 16 rotates to the left and the planetary shaft 1 rotates to the right.
5 and the brush mounting shaft 16 rotate on their own axis and revolve in a counterclockwise circular orbit around the axis of the sun shaft 13, so each tip of the wire rod 4 is brought into uniform contact with the cut surface of the steel pipe for deburring and polishing. It is possible to do this.

In this way, each tip of the wire rod 4 can be uniformly brought into contact with the cut surface of the steel pipe, so that during deburring and polishing, only a portion of the abrasive material that has been focused as in the past comes into contact with the cut surface of the steel pipe. This is completely different from the case where only the wire rod 4 wears out and breaks, and the tip of the wire rod 4 wears out uniformly throughout, extending the life of the abrasive material. Since it is made of a material that has a certain level of strength and a certain line strength that can be used with the palm of your hand, it is possible to remove burrs completely and also to polish it beautifully.

As described in detail above, in the brush for deburring and polishing steel pipes according to the present invention, the wire rod 4, in which the linear polishing material of a predetermined thickness is bundled, is clamped by the cut-off InU-shaped clamping fittings 6. A plurality of annular brush disks 12 are supported and bent into an annular shape, and are arranged in parallel on a disk-shaped substrate 7, and are attached to the substrate 7 at the tips of a plurality of brush mounting shafts 16 that rotate and revolve. It is connected via a fixed flange 9 and has the functions of both deburring and polishing, and when the polishing device 10 is driven and the tip of the wire rod 4 comes into contact with the cut surface of the steel pipe, the wire rod 4 revolves around its own axis and uniformly contacts the cut surface of the steel pipe for deburring and polishing, and the tip of the wire 4 wears out evenly, so the wire 4 has excellent advantages such as a long service life. Since the abrasive material constituting the wire rod 4 is made from a material that has a strength above a predetermined value and a predetermined wire diameter that can perform deburring and polishing,
Buttons have excellent advantages such as being able to completely remove the burr, the cut surface does not become rough during deburring, and the cut surface can be polished to a beautiful surface at the same time as the burr removal. It has great practical value.
