Problems solved by technology
The hot-bending pipe beveling machine tools currently used in China adopt the working principle of the boring machine. Due to the uncertainty of the processing hot-bending pipe angle, there is currently no large-diameter hot-bending pipe beveling machine tool for different bending angles. One end of the workbench is tightened by a fixture, and the other end is lifted by a crane, which seriously occupies equipment such as the crane, resulting in a series of problems such as difficulty in processing and lifting, low processing efficiency, and high equipment occupancy.

Embodiment Construction
[0041] Example. Taking the processing of Φ1016mm, the bending angle of 90° hot simmering bend as an example, the hot simmering elbow beveling machine and its special processing table structure are as follows figure 1 , figure 2 Shown. The fixed bottom plate 9 is fixed to the port leading to the middle groove of the platform base 6 by the hexagon socket screw 10. Two thrust ball bearings 8 are installed on the fixed bottom plate 9. The thrust ball bearing 8 and the lower slider wire are connected by two round nuts. The rod 7 is fixed on the fixed bottom plate 9, the threaded end of the lower slider screw 7 is screwed into the threaded seat of the transverse V-shaped slider 15, the nut 17 is loosened, and the lower slider screw 7 can be rotated to drive the transverse V-shaped slider 15 Move forward and backward; the "V" groove at the lower part of the fixed turntable base 14 is matched with the "V" convex block connected with the horizontal V-shaped slider 15 to form a sliding c...

The invention discloses a workbench for groove machining of large-caliber hot bends. A fixed bottom board (9) provided with two thrust ball bearings (8) and a lower slide block lead screw (7) is fixed at the port communicated with a middle groove of a platform base (6). The threaded end of the lower slide block lead screw (7) is screwed into a threaded base of a transverse V-shaped slide block (15). A V-shaped groove of a fixed rotating disc base (14) is in sliding connection with a V-shaped protrusive block of the transverse V-shaped slide block (15). A movable V-shaped block (11) and the transverse V-shaped slide block (15) are fixed in the middle of the fixed rotating disc base (14) perpendicularly. A circular shaft matched with an upper hole of the fixed rotating disc base (14) is arranged at the lower end of the movable V-shaped block (11). A transverse slide board lead screw (20) is arranged in the center of one end of the transverse V-shaped slide block (15). A fixed V-shaped block (21) is arranged at the other end of the platform base (6) and is perpendicular to the movable V-shaped block (11) in direction. The workbench for groove machining of the large-caliber hot bends shortens the time for assisting in clamping, is rapid to locate and relieves labor intensity.
Description
Technical field [0001] The invention is a special workbench for processing large-diameter hot simmering bends. It involves the processing of metal pipes and the technical field of piping systems. Background technique [0002] In recent years, with the rapid development of domestic oil and gas pipeline construction, my country has to build thousands of kilometers of long-distance oil and gas pipelines every year. Due to the restrictions of the topography and topography of the pipeline sections, the use of hot simmering bends has increased significantly, and The bending angles of the elbows are diverse. The hot simmering pipe bevel processing machine tool currently used in China adopts the working principle of a boring machine. Due to the uncertainty of the processed hot simmering elbow angle, there is currently no application for the processing of large-diameter hot simmering elbows with different bending angles. In the workbench, one end is used for tightening with clamps, and t...
