A first hydraulic cylinder 4 is connected to the side of the die plate 3 away from the middle of the circular groove 2. The clamping mechanism 5 is arranged parallel to the die base 1. The clamping mechanism 5 includes a cross frame 501, a first slide groove 502, a first screw rod 503, a first motor 504, a connecting plate 505 and an arc clamping plate 506. A first slide groove 502 is provided inside the cross frame 501, and a first screw rod 503 is rotatably connected inside the first slide groove 502. The rear end of the first screw rod 503 is connected to the first motor 504. The outer side of the first screw rod 503 is threadedly connected to the connecting plate 5 05, and an arc-shaped clamping plate 506 is fixed at one end of the connecting plate 505 away from the first screw rod 503, and the clamping mechanism 5 is used to fix the pipeline so that the pipeline is suspended just above the circular groove 2, which is convenient for subsequent processing of the bottom end of the pipeline. The connecting plate 505 forms a sliding structure with the cross frame 501 through the first slide groove 502, and two connecting plates 505 and arc-shaped clamping plates 506 are provided, and the inner wall of the arc-shaped clamping plates 506 is fitted with rubber anti-skid pads. By starting the first motor 504, the first screw rod 503 is driven to rotate, so that the two connecting plates 505 threadedly connected to the outside of the first screw rod 503 are close to each other, so that the two arc-shaped clamping plates 506 clamp the pipeline, and the setting of the rubber anti-skid pads reduces the damage caused to the pipeline by the arc-shaped clamping plates 506;

[0024] The longitudinal frame 6 is arranged on the right side of the top end of the mold base 1, and a second slide groove 7 is opened inside the longitudinal frame 6, a second screw rod 8 is rotatably connected inside the second slide groove 7, and a second motor 9 is connected to the top end of the second screw rod 8, a movable block 10 is threadedly connected to the outer side of the second screw rod 8, and the top end of the second screw rod 8 passes through the top end of the longitudinal frame 6 through a bearing and is connected to the output end of the second motor 9, and the second motor 9 is electrically connected to the controller 13, and the second motor 9 is driven to rotate by starting the second motor 9, so that the movable block 10 threadedly connected to the outer side of the second screw rod 8 is lifted and lowered inside the second slide groove 7, thereby driving the movable block 10 to lift and lower, a second hydraulic cylinder 11 is fixed to the left side of the top end of the mold base 1, and a baffle 12 is connected to the output end of the second hydraulic cylinder 11, The outer surface of one end of the movable block 10 is slidably fitted with the inner wall of the second slide groove 7, and the other end of the movable block 10 is fixedly connected to the clamping mechanism 5. This arrangement enables the clamping mechanism 5 to have a lifting function. The number of rotations of the second screw 8 is controlled by the second motor 9, thereby controlling the descending height of the clamping mechanism 5, thereby improving the accuracy of pipeline processing. A controller 13 is installed at the front end of the mold base 1, and the baffle 12 is arranged between the clamping mechanism 5 and the mold base 1, and the baffle 12 and the upper surface of the mold base 1 are parallel to each other.

[0025] Working principle: When in use, first push the baffle 12 to move to the right by the second hydraulic cylinder 11 until the baffle 12 is pushed to the top of the circular groove 2, then take the pipe and place it between the two arc-shaped clamping plates 506, the bottom end of the pipe contacts the upper surface of the baffle 12, then start the first motor 504 to drive the first screw rod 503 to rotate forward, so that the two connecting plates 505 threadedly connected to the outside of the first screw rod 503 approach each other until the two arc-shaped clamping plates 506 clamp the pipe. After the pipe is fixed, the baffle 12 shrinks and moves away from the bottom of the pipe, start the second motor 9, drive the second screw rod 8 to rotate forward, so that the movable block 10 threadedly connected to the outside of the second screw rod 8 descends in the second slide groove 7, and drives the movable block 10 and the clamping mechanism 5 to descend together until the pipe is inserted into the circular groove 2. The length of the pipe extending into the circular groove 2 can be controlled by the number of rotations of the second screw rod 8 according to the actual situation, and the first hydraulic cylinder 4 pushes the mold plate 3 to pressurize and shrink the bottom end of the pipe.
