DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-6 The present application is further described in detail to make the technical solution of the present application easier to understand and grasp.

[0035] Reference Figure 1-Figure 4 The clamping mold 2 includes a connecting plate 21, a fixed clamp block 22 and a sliding clamp block 23. The connecting plate 21 is detachably connected to the frame 1, the fixed clamp block 22 is fixedly connected to the connecting plate 21, the sliding clamp block 23 is slidably connected to the connecting plate 21, and a connecting block 24 is fixedly connected to the sliding clamp block 23. The end of the connecting block 24 away from the sliding clamp block 23 is hingedly connected to a hinge block 25, and the end of the hinge block 25 away from the connecting block 24 is hingedly connected to a driving block 26. The end of the driving block 26 away from the hinge rod 331 is hinged on the connecting plate 21, and a force handle 27 is fixedly connected to the driving block 26. When the sliding clamp block 23 slides to abut against the fixed clamp block 22, the length directions of the hinge block 25 and the driving block 26 are collinear with the sliding direction of the connecting block 24.

[0036] Reference Figure 1-Figure 4 Through the principle of the hinged four-bar mechanism, when the hinge block 25 and the driving block 26 are collinear, that is, the dead point position, the movement of the connecting block 24 is limited, thereby locking the position of the sliding clamp block 23, reducing the situation where the sliding clamp block 23 cannot clamp the oil pipe, and facilitating the use of the pier head machine.

[0037] Reference Figure 1-Figure 4 The fixed clamp block 22 is fixedly connected with a guide block 221, and the sliding clamp block 23 is provided with a guide groove 231 that can cooperate with the guide block 221. When the sliding clamp block 23 slides to cooperate with the fixed clamp block 22, the sliding guide block 221 cooperates with the guide groove 231. Through the cooperation between the guide block 221 and the guide block 221, the movement of the sliding clamp block 23 is guided and limited, reducing the possibility that the sliding clamp block 23 deviates during the movement, resulting in the inability to tighten the oil pipe or the deformation of the formed pier head.

The movement of the connection block 24 is limited by the plurality of limit plates 28, so as to reduce the possibility that the sliding clamp block 23 is offset during the movement, resulting in the inability to tighten the oil pipe or the deformation of the formed pier head, and reduce the possibility that the intersection block and the driving block 26 cannot be collinear.

[0039] Reference Figure 1-Figure 5 The pier mechanism 3 includes a punch block 31, a piston column 32 and a driving assembly 33. The piston column 32 is slidably connected to the frame 1 in the vertical direction. The punch block 31 is detachably connected to the piston column 32. A threaded hole is provided on the piston column 32. The end of the punch block 31 away from the fixed clamp block 22 is threadedly connected to the piston column 32. The driving assembly 33 is used to drive the piston column 32 to slide. When the driving assembly 33 drives the piston column 32 to slide toward the fixed clamp block 22, the punch block 31 cooperates with the fixed clamp block 22 and the sliding clamp block 23. The piston column 32 is driven to reciprocate by the driving assembly 33. When the driving assembly 33 drives the piston column 32 to slide toward the fixed clamp block 22, the punch block 31 cooperates with the fixed clamp block 22 and the sliding clamp block 23 to perform pier operation on the oil pipe.

[0040] Reference Figure 1-Figure 5The driving assembly 33 includes a hinge rod 331, a turntable 332, a swivel 333 and a driving source 34.

The turntable 332 is connected to the piston column 32 in a vertical direction. The rotation axes of the swivel 333 and the turntable 332 are not coaxial. The two ends of the hinge rod 331 are respectively hingedly connected with a cross shaft 334. The two cross shafts 334 are respectively hingedly connected to the adjusting block 351 and the turntable 332. The driving source 34 is used to drive the rotation of the swivel 333. The rotation of the swivel 333 drives the hinged rod 331 to move. When the end of the hinged rod 331 away from the piston column 32 rotates to be close to the piston column 32, the piston column 32 moves toward the side of the fixed clamping block 22, thereby forming an impact force, causing the workpiece to produce a specified deformation in the clamping mold 2 to achieve the processing purpose. When the end of the hinged rod 331 away from the piston column 32 rotates to be away from the piston column 32, the piston column 32 moves toward the side away from the fixed clamping block 22.

The first pulley 342 is coaxial and fixedly connected to the output shaft of the driving motor 341. The second pulley 343 is coaxial with the rotation axis of the swivel 333 and fixedly connected to the swivel 333. The first pulley 342 and the second pulley 343 are simultaneously wound and connected by the conveyor belt. Starting the first motor rotates the first pulley 342, and through the transmission connection of the conveyor belt, the second pulley 343 rotates together, thereby rotating the swivel 333.

[0042] Reference Figure 1-Figure 6 , and also includes an adjusting member 35, which is used to adjust the position of the adjusting block 351 on the swivel 333. By adjusting the position of the adjusting block 351 on the swivel 333, the stroke position of the piston column 32 can be adjusted, which is convenient for the use of the pier head machine. The adjusting member 35 includes a threaded rod 352 and a knob 353, the threaded rod 352 is rotatably connected to the swivel 333 along the direction of the swivel 333, the threaded rod 352 is penetrated and threadedly connected to the adjusting block 351, and the knob 353 is coaxially and fixedly connected to the threaded rod 352. The threaded rod 352 is rotated by rotating the knob 353, and the adjusting block 351 is moved along the axial direction of the threaded rod 352 through the threaded connection between the threaded rod 352 and the adjusting block 351 to adjust the position of the adjusting block 351 on the swivel 333.
