Description

Technical Field

[0001] The utility model relates to the technical field of pipe bending, and more specifically to a hot pipe bending processing device for an oil pipe joint. Background Art

[0002] Oil pipe joints refer to a joint device used to connect oil pipes in the industrial field, especially in the fields of petroleum, chemical industry, hydraulics, etc. The current pipe bending device has low efficiency and a relatively simple bending degree of the pipe. In addition, it is inconvenient to disassemble the pipe after the pipe is bent.

[0003] After searching, a Chinese patent with announcement number CN214290192U discloses a brake oil pipe quick bending device, including a workbench, the inner wall of which is fixedly connected to a motor, and the motor drives the clamping blocks to move left and right, thereby changing the distance between the clamping blocks to achieve different degrees of bending of the pipe, thereby improving the applicability of the bending device and diversifying the bending degree of the pipe.

[0004] When the above patent is in use, the upper module is placed on the lower module and the upper module and the lower module are assembled by fixing bolts. After the pipe bending is completed, the fixing bolts are removed to remove the pipe from the clamping block. However, manual installation and removal of the fixing bolts are required, the operation is cumbersome, and the labor intensity of the staff is high. Utility Model Content

[0007] Furthermore, the first limiting assembly includes a limiting frame, an insert block, a threaded insert rod and two extrusion sleeves, the top end of the insert block is fixedly connected to the limiting frame, and the bottom end of the insert block extends into the mounting seat, and one end of the threaded insert rod passes through the mounting seat, the insert block and the two extrusion sleeves.

[0008] Furthermore, the second limiting assembly includes a first limiting sleeve, a first hydraulic cylinder and a first fixed block, the rear end of the first hydraulic cylinder is fixedly mounted on the mounting seat, and the front end of the first hydraulic cylinder is fixedly connected to the first fixed block, and the rear side of the first limiting sleeve is inserted into the first fixed block.

[0014] Technical effects and advantages of the utility model:

[0015] 1. The utility model drives the first fixed block close to the oil pipe joint by extending the piston rod on the first hydraulic cylinder, thereby driving the first limit sleeve close to the oil pipe joint. Similarly, the second hydraulic cylinder can drive the two second limit sleeves close to the oil pipe joint. The motor drives the rotating shaft to rotate, thereby driving the mounting seat to rotate and away from the third fixed block, and then drives the first limit sleeve to rotate. The oil pipe joint is bent by the first limit sleeve, and the extrusion of the oil pipe joint is eliminated. The operation is simple and the labor intensity of the staff is effectively reduced.

[0016] 2. The utility model rotates the extrusion sleeve and moves it away from the threaded rod, thereby releasing the fixation between the threaded rod and the insert block, takes out the threaded rod, thereby releasing the fixation between the insert block and the mounting seat, and repairs and replaces the limit frame.
