BACKGROUND OF THE INVENTION
The present invention relates to a workpiece vibration device that fills a workpiece with powder or discharges the filled powder by vibrating the workpiece.
[0002]
[Prior art]
In general, to bend the double pipe 71 as shown in FIG. 11 with a pipe bender or the like, a space 74 between the outer pipe 72 and the inner pipe 73 of the double pipe 71 is filled with powder 75 such as ceramic balls. Thus, the outer tube 72 and the inner tube 73 are bent at the same time so that the bending pressure acting on the outer tube 72 is applied to the inner tube 73 via the powder 75 filled. In such a double tube 71, as shown in FIG. 11, a space 74 between the outer tube 72 and the inner tube 73 is closed at one end, and the outer tube 72 and the inner tube 73 are closed from the other end. The powder 75 as the filler is injected into the space 74 between the outer tube 72, the outer tube 72 is then struck with an air hammer 77 (see FIG. 12), and the powder 75 is vibrated. The powder 75 was filled between the 72 and the inner tube 73. After filling the powder 75, the plug member 79 is fitted into the powder injection port 78 of the double pipe 71, the double pipe 71 is bent by a pipe bender or the like, and then fitted into the double pipe 71. The plug member 79 is removed using a jig or the like, and as shown in FIG. 12, the powder 75 as a filler is discharged from the powder injection port 78 by striking the double pipe 71 again with the air hammer 77. It has been performed conventionally.
[0003]
However, in the conventional method of hitting the double pipe 71 with the air hammer 77 and filling the powder 75 as the filler or discharging the filled powder 75, the double pipe which is a product by hitting the air hammer Since 71 was damaged, the process for repairing the wound increased and the work efficiency was poor. In addition, the loud noise and vibration generated when the air hammer 77 and the double pipe 71 collide worsen the working environment, and the dust floats in the atmosphere and adheres to the sliding part of the machine and the control device. This could cause a failure of surrounding machines. Moreover, since the cross-sectional shape of the double pipe 71 is deformed by bending the double pipe 71, removing the plug member 79 after the bending process is laborious and laborious.
