[0031] The moving parts include two groups of transmission parts, a rotating motor and a double-headed screw. The rotating shaft of the rotating motor is fixedly connected to one end of the double-headed screw, and the rotating motor is fixedly connected to the base 2. Each group of transmission parts includes a connecting rod, a transmission wheel and a rotating wheel 7. The two ends of the connecting rod are respectively fixedly connected to the rotation center of the transmission wheel and the rotating wheel 7. The outer ring of the transmission wheel is provided with teeth. The transmission wheels of the two groups of transmission parts are respectively meshed with the two ends of the double-headed screw for transmission. At least one protrusion 8 is provided on the two rotating wheels 7. The first ends of the two sliders 5 are provided with sliding grooves 9. The two sides of the protrusion 8 are arc structures. The protrusion 8 is located in the sliding groove 9. The protrusion 8 is in extrusion contact with the slider 5. The rotating wheel 7 can be rotatably installed in the base 2. The rotating motor, double-headed screw and transmission wheel of the moving parts are not shown in the figure, but they are all.

[0032] A rotation limiting member is installed in one of the sliders 5, and the rotation limiting member includes a driving rod 10, a gear 11, a power source, a limiting rod 12 and a limiting wheel 13. The side wall of the limiting rod 12 is provided with teeth, and the limiting rod 12 is meshed with the gear 11 for transmission. The outer wall of the limiting wheel 13 is provided with at least one limiting groove 14, and the limiting wheel 13 is fixedly connected to the second end of one of the mouth guards 3.

The elastic member 15 is a compression spring.

[0035] The working principle of the hydraulic two-jaw manual rotary chuck used for die forging pipe joints of the utility model is as follows:

[0036] When the die-forged pipe joint 1 needs to be processed, the two sliders 5 are first driven by the moving part to move in a direction away from each other, so that the distance between the first ends of the two mouth guards 3 increases, and then the die-forged pipe joint 1 can be placed in the fixed groove 4. After the placement is completed, the moving part drives the two sliders 5 to move in a direction close to each other, so that the distance between the first ends of the two mouth guards 3 decreases, until the fixed grooves 4 of the two mouth guards 3 are respectively pressed and contacted with the two sides of the die-forged pipe joint 1;

[0037] When the angle of the die-forged pipe joint 1 needs to be adjusted, the driving rod 10 and the gear 11 are rotated by using a wrench tool, so that the limiting rod 12 moves in a direction away from the limiting wheel 13, until the first end of the limiting rod 12 leaves the limiting groove 14 of the limiting wheel 13, at which time the mouth guard 3 can be rotated manually or by using other tools to rotate, so that the die-forged pipe joint 1 is in the correct position, and the compression spring is compressed again in this process to store energy; after the adjustment is completed, the wrench tool is released, and at this time the driving rod 10 and the gear 11 lose the external force, and the compression spring releases energy, so that the limiting rod 12 moves in a direction close to the limiting wheel 13, until the first end of the limiting rod 12 enters the limiting groove 14 of the limiting wheel 13, so that the die-forged pipe joint 1 and the base 2 are in a relatively static state during the processing. The shape of the working end of the wrench tool matches the shape of the inner concave hole 16.

[0038] The technical solution of the present utility model is not limited to the above-mentioned specific embodiments, and all technical variations made according to the technical solution of the present utility model fall within the protection scope of the present utility model.
