Abstract
Description
Technical Field

The cam 1.3 is positioned above the concave wheel 1.2. Both sides of the cam 1.3 and the concave wheel 1.2 are mounted on sliders 1.4. The sliders 1.4 are connected to the pressure roller frame 1.1 via side guide rails. Adjusting screws 1.5 are mounted on the top of the sliders 1.4 on both sides of the cam 1.3. The adjusting screws 1.5 are threadedly connected to the pressure roller frame 1.1. The end of the adjusting screw 1.5 is limited within the slider 1.4 and can rotate, driving the slider to move up and down. Figure 6 , Figure 7 As shown, the transverse forming device 2 includes two transversely arranged forming rollers 2.1. Each forming roller 2.1 includes a fixed shaft 2.2, an adjusting shaft 2.3, and a transverse support 2.4. The fixed shaft 2.2 is fixed to the transverse support 2.4 by bolts. The transverse support 2.4 has a groove 2.5, and an adjusting slider 2.6 is arranged in the groove 2.5. The adjusting slider 2.6 is connected to the adjusting shaft 2.3 by a pin. A bolt 2.7 is provided on one side of the adjusting slider 2.6. The bolt 2.7 is connected by... The threaded connection is to the transverse support 2.4. The end of the bolt 2.7 is limited in the adjusting slider 2.6 and can move it left and right. The adjusting slider 2.6 is connected to the adjusting shaft 2.3 by a pin. When the bolt 2.7 moves the adjusting slider 2.6, the adjusting shaft 2.3 can tilt, which can better press the pipe fitting end into alignment. The adjusting shaft 2.3 is equipped with adjusting sliders 2.6 at both the upper and lower ends to change the tilt angle of the adjusting shaft 2.3 relative to the fixed shaft 2.2, so that the upper end of the pipe fitting is more smoothly aligned.

[0017] During operation, the coiled steel strip is initially bent by several sets of pressure roller devices 1 through the cooperation of concave rollers 1.2 and cams 1.3. After bending, it enters the transverse forming device 2 and the longitudinal forming device 3 to be formed into a circular outline. The transverse forming device 2 moves the adjusting slider 2.6 in the groove 2.5 by adjusting the screw 1.5, thereby tilting the axis of the adjusting shaft 2.3 relative to the axis of the fixed shaft 2.2. When the tube is formed, the top of the tube can be pressed inward to the maximum extent. Then, it is further formed into a round shape by the longitudinal forming device 3, and then further shaped into a standard shape by the shaping device 4.
