Abstract

There is disclosed an equal strength hose connector clip and its manufacture method. The clip includes a clip body and ear-seats at both ends of the clip body. The manufacture method includes the following steps of setting the thickness of the clip in equal strength proportions; rolling the steel band blanks; cutting out the steel band blank of the corresponding length; milling the blank into the ring body using the roller mould under the condition of normal temperature and then being separated into half-round clip bodies to be made the inventive clip after welding the ear-seats.

Description

1. Technical field:

[0001] The invention belongs to the technical field of pipeline connection, and in particular relates to a flexible pipe joint clamp and a manufacturing method thereof. 2. Background technology:

[0002] The currently known flexible pipe joint clamps include a clamp body and ear seats at both ends of the clamp. The wall thickness of the clamp body is the same everywhere. Through accurate calculations, the inventors have found that the forces on the clamp body wall are different everywhere, and the wall thickness of each place is the same. The same cannot achieve equal strength and maximize the use of steel, and the wall thickness can be set according to the magnitude of the force to save steel; the known manufacturing methods of flexible pipe joint clamps are generally made by casting technology and hot stamping technology, and the casting technology can manufacture various There are various shapes of clamps, but the process is complicated, the production...
