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 Φ1016 pipes with a bending angle of 90° as an example, the structure of the hot-simmering pipe beveling machine and its special processing table is as follows figure 1 , figure 2 shown. The fixed bottom plate 9 is fixed on the port leading to the middle groove of the platform base 6 by the inner hexagonal screws 10, two thrust ball bearings 8 are installed on the fixed bottom plate 9, and the thrust ball bearings 8 and the lower slider wire are connected by two round nuts. The bar 7 is fixed on the fixed base plate 9, the threaded end of the lower slider screw 7 is screwed into the threaded seat of the horizontal V-shaped slider 15, the nut 17 is loosened, and the lower slider screw 7 can drive the horizontal V-shaped slider 15 Move back and forth; the "V" groove at the lower part of the fixed turntable base 14 cooperates with the "V" bump that is integrated with the horizontal V-shaped slider 15 to form a sliding connection; the mova...

Abstract

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 bevel processing of large-diameter hot-simmered bent pipes. It relates to 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 constraints of the topography and other conditions of the pipeline laying section, the use of hot-simmered elbows has increased significantly, and The bending angle of the elbow is diverse. 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 ...
