Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Referring to the accompanying drawings, a permanent extrusion type pipe joint crimping tool disclosed by the present invention includes an oil cylinder and a crimping head, the oil cylinder is connected with a manual hydraulic pump or an electric pump, and the crimping head is After the bit groove slides in, the oil cylinder is buckled and connected with the crimping head, and the power provided by the manual hydraulic pump or electric pump is given to the oil cylinder, and the oil cylinder pushes the crimping head to extrude the pipe joint to deform the pipe joint to form a connection. The unit of the size of the crimping part of the crimping head is set to the metric unit.

[0024] The crimping head includes a jacket 1, an upper mandrel 2, a lower mandrel 3, and a slider 4, wherein the upper mandrel 2 and the lower mandrel 3 are arranged togeth...

Abstract

The invention discloses a permanent extrusion type pipe joint crimping tool. The tool comprises an oil cylinder and a crimping head, wherein the oil cylinder is connected with a manual hydraulic pump or an electric pump, after the crimping head slides in along a buckling groove of the oil cylinder, the oil cylinder is in buckling connection with the crimping head, power provided by the manual hydraulic pump or the electric pump is supplied to the oil cylinder, and the oil cylinder pushes the crimping head to extrude a pipe joint, so that the pipe joint is deformed to form connection, and the unit of the size of a crimping part of the crimping head is set as a metric unit. The tool has the beneficial effects that by arranging the metric crimping head, the crimping problem of domestic metric pipes is solved, and by arranging the crimping head and the oil cylinder for sliding buckling connection, the tool is easy to assemble and disassemble and convenient to use.

Description

technical field [0001] The invention relates to the technical field of aircraft hardware tools, in particular to a permanent extrusion type pipe joint crimping tool. Background technique [0002] From the development trend, the external extrusion permanent pipe joint is the main hydraulic conduit connection method adopted by some foreign advanced models. It has technical maturity and quality reliability, which can better reduce weight, reduce leakage and improve reliability. , At the same time, the installation is flexible, which can reduce the space used for laying pipelines, simplify the installation procedure, facilitate inspection, simplify quality control, provide the possibility of laying conduits in the machine, and can absorb structural tolerances (assembly error accumulation) for continuous Bending can also compensate for the possible impact of aircraft structural changes on the pipeline, and is an important development direction for the connection technology of the h...
