[0019] Figure 1 The first embodiment of the present invention is shown. This embodiment includes a frame 1, a rolling inner die 2, a rolling outer die 4, a cam 10, and an ejector rod 9. The ejector rod 9 is provided with a roller 7. The rolling outer die 4 is arranged on a rolling outer die seat 6, and an adjusting screw pair is arranged between the rolling outer die seat 6 and the ejector rod 9 for adjusting the distance therebetween. The adjusting screw pair includes a screw 8 and a nut 3. The screw 8 is fixedly arranged on the ejector rod 9. A bearing 5 is arranged at the upper part of the adjusting screw pair. The bearing 5 is a thrust bearing. The bearing 5 is arranged above the nut 3. When adjusting the distance between the rolling outer die seat 6 and the ejector rod 9, since the weight of the rolling outer die seat 6 is transmitted to the bearing 5, it is very easy for the operator to rotate the nut 3 by hand.
[0020] Figure 2The second embodiment of the present invention is shown. This embodiment includes a frame 1, a rolling inner mold 2, a rolling outer mold 4, a cam 10 and a push rod 9. The push rod 9 is provided with a roller 7. The rolling outer mold 4 is arranged on a rolling outer mold base 6, and an adjustable screw pair is arranged between the rolling outer mold base 6 and the push rod 9 for adjusting the distance therebetween. The adjustable screw pair includes a screw 8 and a nut 3. The screw 8 is fixedly arranged on the push rod 9. A bearing 5 is arranged at the upper part of the adjustable screw pair. The bearing 5 is a self-lubricating thrust gasket. The bearing 5 is arranged on the nut 3. When adjusting the distance between the rolling outer mold base 6 and the push rod 9, since the weight of the rolling outer mold base 6 is transmitted to the bearing 5, it is very easy for the operator to turn the nut 3 by hand.
[0021] Figure 3 The third embodiment of the present invention is shown. This embodiment includes a frame 1, a rolling inner mold 2, a rolling outer mold 4, a cam 10 and a push rod 9.
