The present invention relates to a drawing die automatic self-aligning device for drawing the pipe thinner.

Previously, there was a drawing die automatic watchdog. That is, the aperture when drawing the pipe 6

After adjusting the diameter with the cutting device (5, 5 '), it was drawn. For example, a pipe with a diameter of 8 cm

In the case of drawing with a 5cm pipe, adjust the drawer to adjust the diameter to 5cm.

When the pipe (6) is injected through the pipe inlet (7), the pipe with a diameter of 8 cm is adjusted

Through the adjusting device (5,5 '), the pipe is 5cm in diameter and drawn out through the pipe outlet (8).

All. However, the die of the existing device (4,4 ') is inevitably □-or ○ -shaped.

The gap occurred when assembling the caliber adjusting device (5,5 '). Therefore, centering automatically

He said that he bowed, but he couldn't really be careful. Moreover, the existing chapter

The housing support (2), the die holders (3, 3 ') and the housing (1, 1')

As a result of the tightening, there is no play between the die holders (3,3 ') and the housing support (2).

It was more impossible to watch out. Thus, the pipe is drawn to the center

This had to be adjusted manually to add.

Furthermore, the diameter adjusting device is drawn into the pipe inlet 7 to draw the pipe 6.

When passing through ((5,5 '), the pipe must pass through a narrow aperture, so frictional heat is generated, which inevitably generates a lot of heat. Since it was necessary to draw into the pipe inlet 7 after applying to 6), there was also a lot of inconvenience, such as human hand takes.

   The present invention has been made to solve the above-mentioned conventional problems, the main object is to draw the oil into the pipe when drawing the pipe into the automatic monitoring device as well as draw the pipe quickly and accurately by automatically centering the die (調 心) The purpose is to automatically draw the pipe by literally applying the.

     A feature of the device according to the present invention for achieving the above object is that a slight inclination of the die and the die holder is possible to allow play, while the die holder and the housing support are joined by using an elastic body to generate the pipe. The play can be adjusted more smoothly. In addition, through the housing, the die holder, and the die is provided with a drawing oil inlet, the drawing oil supplied from a separate drawing oil tank is automatically applied to the pipe to relieve friction to prevent heat generation in advance to draw the pipe more smoothly I could do it.

 Hereinafter, the drawing die automatic self-aligning device according to the present invention will be described in detail with reference to the accompanying drawings.

As illustrated in FIG. 2, for example, when the pipe 18 having a diameter of 8 cm is to be drawn out with a pipe having a diameter of 5 cm, the distance between the adjusting devices 15 and 15 ′ is adjusted to 5 cm, and then the pipe 18 is connected to the pipe inlet ( 19). The pipe 18 introduced as described above is drawn out through the pipe outlet 20 while the diameter is narrowed to 5 cm while passing through the aperture adjusting devices 15 and 15 ′. However, when drawing the pipe in this way, the pipe is long and wobbly, so it is very difficult for the die to center. Therefore, it is necessary to automatically center the die so that the pipe can be drawn out smoothly.

In this case, if the die holders 13 and 13 'and the dies 14 and 14 are slightly inclined, the dies are flowed together in accordance with the flow of the drawn pipes, so that the assembly gap as in the conventional apparatus is generated. This essentially eliminates the possibility of drawing the pipe 18 stably and automatically. At this time, the inclination gives the die holders 13, 13 'and the dies 14, 14 equally to 3 degrees-7 degrees, respectively, but the most preferable inclination angle is 5 degrees, respectively. Thus, by giving the same angle of inclination to the die holders 13, 13 'and the dies 14, 14, the center of the die can be accurately positioned.

In addition, by connecting the housing support 12 and the die holders 13 and 13 'by using an elastic body 16 such as rubber or a spring, the flow of the die holder 13 according to the flow of the pipe 18 is further affected. It is possible to stably adjust the center of the die.

On the other hand, when drawing the pipe 18 having a diameter of 8cm to 5cm in diameter, a lot of heat is generated due to strong friction, and thus a lot of detrimental effects are generated, such as deformation of the drawn pipe, thereby preventing the occurrence of such heat. In order to prevent heat generation in advance, oil must be applied to the pipe to lubricate the pipe so that the friction can be smoothly drawn.

In the present invention, a drawing oil supplied from a drawing oil storage tank (not shown) is formed through the housing 11, the die holder 13, and the die 14 of the self-aligning device to form a drawing oil supply port 17. The free drop through the oil supply port 17 is automatically applied to the pipe 18 by lubricating the pipe to reduce the frictional force was able to automatically draw the pipe 18 more smoothly.

 As seen from the above, the present invention provides a device for automatically adjusting the center of the die by giving a slight inclination to the die holder and the die, thereby eliminating the assembly gap due to the flow of the pipe, as well as installing the oil inlet automatically. By applying the drawing oil to the pipe, the heat generated when the pipe is drawn can be automatically eliminated in advance.
