Hydraulic device for bending pipe parts

Abstract

The invention discloses a hydraulic device for bending pipe parts. The hydraulic device comprises a main plate rack, one side position of the upper portion of the main plate rack is provided with a jacking oil cylinder, the jacking oil cylinder is matched with a pipe jacking head, an upper inclined plane of the pipe jacking head is rotatably provided with a plurality of rotating rollers, the otherside position of the upper portion of the main plate rack is detachably connected with a supporting plate rack, two side positions of the upper portion of the supporting plate rack are both providedwith holding plate racks in a welded manner, the upper portions of the holding plate racks are connected with an installation plate rack, one end of the installation plate rack is provided with a downpressing plate rack in a welded manner, the holding plate racks are connection with position-limiting screw rods in a screwed manner, the upper portion of the installation plate rack is provided witha fixed oil cylinder, the fixed oil cylinder is matched with a fixed pressing plate, the down pressing plate rack is provided with a down pressing oil cylinder, the middle position of the lower portion of the main plate rack is provided with a clamping rack in a welded manner, and the clamping rack is connected with a clamping bolt in a screwed manner. The hydraulic device for bending the pipe parts is installed on the edge position of a workbench, operators perform pipe bending operations conveniently, the once or twice bending work of the pipe parts can be performed in groups, and the uniformity of bending angles of the pipe parts is good.

Description

technical field [0001] The invention relates to the field of mechanical pipe bending devices, in particular to a hydraulic device for bending pipe fittings. Background technique [0002] In mechanical production work and on-site construction work, plumbing pipes and various plastic pipes often need to be bent when they are used. At present, when performing pipe bending operations, bending pipe springs are generally used, and the staff need to extend the bending pipe springs into the pipe fittings In the process of bending pipe fittings by external force, the operation is laborious, and it is often necessary to bend multiple pipe fittings during construction. Such an operation method makes the bending operation take a long time, and the bending range is The operating angle of each bending is difficult to be the same and it is difficult to obtain precise control. Now a device for bending pipes in groups is needed to solve the above problems and improve the efficiency and preci...
