[0036] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The hydraulic joint production bending device of the present application is mainly composed of a bending machine body 1 and a bending disc 101 to perform bending operations on pipe fittings. A slider is provided at one end of the pipe fitting away from the bending disc 101 to apply pressure to the pipe fitting, so that the pipe fitting can be bent according to a predetermined path on the bending disc 101. When bending, a positioning outer frame 2 is surrounded by the outside of the bending disc 101, and a fixed bracket 201 is installed at the bottom of the positioning outer frame 2 and fixed to the bending machine body 1 by bolts. A stabilizing end tube 7 is provided between the fixed bracket 201 and the bending part of the pipe fitting, so that the stabilizing end tube 7 is sleeved on one end of the pipe fitting to be bent without contacting the bending part and can move relative to the pipe fitting, thereby completing the connection between the bending disc 101 and the pipe fitting. Then, when the slider applies pressure to the pipe fitting, the stabilizing end tube 7 moves relative to the pipe fitting, and at the same time, an arc-shaped groove is provided on the positioning outer frame 2 so that the movable part 3 can move therein. The movable part 3 can move in the groove of the positioning outer frame 2 relative to the bending disk 101. When the pipe fitting is bent and rotated in the relative path of the bending disk 101, the movable part 3 is driven in the same direction to move in the groove of the positioning outer frame 2, so that the end of the pipe fitting to be bent and the bending disk 101 are connected without repulsive movement.
