It is said that the optimum processing conditions can be selected.

On the chamfering stage (B) set on the downstream side of the support stage (A), two rotary brushes (8) and (8) are arranged on both sides of the base (1). Has been done.
As shown in detail in FIG. 4 and FIG. 5, these rotary brushes (8) have a large number of nylon brushes (81) planted on the peripheral surface, and the axial direction thereof is the longitudinal direction of the base (1). In other words, they are arranged so as to match the arrangement direction of the aluminum tubes (30). Further, each rotating brush (8) is driven by a motor (9) installed above to rotate by a belt. These rotating brushes (8) are brought into contact with the peripheral edge of the aluminum pipe (30) which is conveyed to and passes through the chamfering stage (B) by the movement of the moving table (2), so that the rotating peripheral surface of the aluminum brush (30) contacts the aluminum. The chamfering of the edge of the pipe (30) is performed. Therefore, the rotary brush (8) is arranged such that its peripheral surface slightly extends into the passage area of the aluminum pipe (30). Moreover, even if the length of the aluminum pipe to be treated is changed or the brush is worn, the handle (10) is provided so as to ensure an appropriate amount of contact between the peripheral surface of the rotating brush (8) and the end of the aluminum pipe. The amount of advancing / retreating of the rotating brush (8) in the direction of the base (1) can be adjusted by means of (). Further, although not shown, an adjusting screw is attached to the mounting base (11) of the rotating brush (8) so that the position of the rotating brush (8) can be adjusted up and down. It is said that the degree of brushing can be adjusted according to the outer diameter and the like.

In the take-out stage (C) set on the downstream side of the chamfering stage (B), a take-out device (which releases the aluminum pipe (30) passing through the rotary brush (8) from the supporting device (4) ( 20) is provided. This take-out device (2
0) includes support plates (21) having an L-shaped cross section, which are arranged on both sides of the base (1) along the base (1).

In this state, a plurality of aluminum pipes (30) transferred from the previous step are transferred onto each support device (4) by a transfer mechanism (not shown). After that, the lift table (6) descends and the friction roller (51) of the rotation imparting device (5) contacts the upper peripheral surface of each aluminum tube (30). When the motor (53) on the lift table (6) is rotated, the gear transmission mechanism (52) causes the friction roller (51) to rotate, so that the aluminum tube (30) in contact with the roller rotates about its own axis. Rotate to.

Then, the movable table (2) advances to the chamfering stage (B) along the base table (1). The rotary brush (8) of the chamfering stage (B) is rotationally driven by the motor (9). Aluminum pipes that have been transported (30)
From the aluminum pipe on the downstream side thereof sequentially enters the rotating region of the rotating brush (8), and both end edges of the aluminum pipe (30) are chamfered in contact with the rotating peripheral surface of the rotating brush (8), resulting in burr, etc. Are removed. During this time, the movable table (2) moves without stopping, and the aluminum tube (30) sequentially enters the rotating brush (8) and is continuously chamfered. The chamfering work is carried out until the moving table (2) moves and the aluminum pipe (30) passes through the rotating range of the rotating brush (8).
Since each aluminum tube itself also rotates during the chamfering step, chamfering is performed uniformly over the entire periphery of the aluminum tube (30).

The moving table (2) which has passed through the chamfering stage (C) reaches the take-out stage (C) and stops. Then, after the lift table (6) rises, the support plate (21) of the take-out device (20) rises to bring the V-shaped support portion (23) into contact with the lower peripheral surfaces of both ends of the aluminum pipe and raise it as it is. The aluminum tube (30) is released from the supporting device (4), and then the movable table (2) is retracted to the supporting stage (A) to stand by for supporting the next aluminum tube. The aluminum pipe (30) supported by the support plate (21) is delivered to the next process by a delivery device (not shown).

When the length of the aluminum pipe (30) is changed or when the rotating brush (8) is worn, the handle (10) is operated to move the rotating brush (8) to the aluminum pipe (8). It is enough to enter the passage area of 30). Further, the chamfering conditions may be set optimally by adjusting the rotation speed of the friction roller (51) according to the material of the aluminum tube or other tube material or the material of the brush.

In the illustrated embodiment, the rotating brush (8)
The rotary brush (8) is fixed without moving in the axial direction, and the aluminum tube (30) is moved with respect to the rotating brush (8) by moving the moving base (2). It may be possible to adopt a configuration in which it is moved with respect to 30).
