Buckling device used for pipe buckling joints

Abstract

The invention provides a buckling device used for pipe buckling joints. A front end supporting plate is connected to a tail end supporting plate through four horizontal guide columns, and the two endsof each horizontal guide column are fixed through round nuts; an intermediate movable plate is installed on the horizontal guide columns through sliding sleeves and can slide left and right along thehorizontal guide columns; the tail parts of two hydraulic jacks are fixed on the front end supporting plate, and the front ends of the hydraulic jacks are provided with connecting seats; the connecting seats are fixed on the intermediate movable plate through bolts; an outer buckle support sleeve is inlaid in the front end supporting plate in an interference fit manner; an outer buckle module oran internal expansion support sleeve is inlaid in the intermediate movable plate and fixed through a fixing flange; and a mold seat is connected to the tail end supporting plate by cooperating with ashaft hole. According to the technical scheme, good guidance quality during buckling can be guaranteed by adopting the double oil cylinder and the four horizontal guide columns, high precision buckling can be realized; screw thread or mosaic structures can be adopted when a mold is changed, so that convenient changing can be achieved; and an internal expansion head and the outer buckle module areeasy to change, so that convenient operation can be realized, working efficiency of buckling can be enhanced, production costs can be reduced, and therefore, the buckling device is suitable for work under various harsh conditions and has a certain economic value and using value.

Description

technical field [0001] The invention relates to a crimping device for crimping joints of pipelines. Background technique [0002] With the rapid development of the petroleum industry, the connection between oilfield pipelines has become a key problem that manufacturers must first solve. If the pipeline connection is not good, there will be leakage at the joint at any time. In the current technology, the device of the pipe joint is usually realized by crimping with a crimping device. However, the existing crimping devices have problems such as low crimping accuracy, complicated operation, and inconvenient mold replacement to varying degrees, which can easily cause the pipe joint to fall off, thereby affecting the service life of the pipeline and increasing the use cost. [0003] It is against this background that this patent proposes a crimping device for crimping joints of pipelines. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the pre...
