Abstract

Disclosed is a device for closing in a tightening nut and a pipe joint module through an oil press. The device comprises a base, a closing low mold, a core rod, a mold core, a closing upper mold, a closing sleeve, an adjusting cushion and a limiting seat. The base is arranged on the workbench of the oil press; the mold core is threadedly arranged inside the core rod; the mold core and the core rod are arranged inside the base; the closing lower mold is arranged in transition fit inside the base; the limiting seat is arranged on the workbench of the oil press; the base is arranged inside the limiting seat; the adjusting cushion is arranged inside a shallow circular truncated cone at the upper end of the limiting base; the closing upper mold is arranged on the closing lower mold; the closing sleeve is arranged on a hydraulic press connecting seat. The device for closing in the tightening nut and the pipe joint module through the oil press is small in size, compact in structure, simple in operation, high in loading and unloading speed, accurate in axial and radial positioning of parts, high in consistency of closed portions of the closed parts, uniform and stable in experimental data and high in product percent of pass.

Description

technical field [0001] The invention relates to a device for closing a tightening nut and a pipe joint assembly, in particular to a device for closing a tightening nut and a pipe joint assembly by using a hydraulic press. Background technique [0002] At present, the flaring type with tightening nut variable diameter right angle pipe joint used in aviation and aerospace fields, the flared type with tightening nut right angle pipe joint, the flared type with tightening nut elbow joint, the flared type with tightening nut Asymmetrical three-way pipe joints Flared type with double tightening nuts Symmetrical three-way pipe joints, flared type with tightening nuts Asymmetrical D-type variable-diameter three-way pipe joints and other types of product parts and components are all used on the lathe Jaw single action chuck for closing. Due to the radial runout of the chuck and the free play of the jaws, the radial size of the mouth is unstable and poor in consistency. The pass rat...
