Abstract
The utility model relates to the technical field of automobile air-conditioner system pipes, in particular to an external thread connector of an automobile air-conditioner pipe, which is formed by a metal threaded pipe head and a metal pipe body element, and is characterized in that the metal threaded pipe head is sleeved on a flare of the metal pipe body to be pressed to form a finished product. Strength, gas tightness and abrasive resistance of the external thread connector of an automobile air-conditioner pipe are improved, and the processing of the external thread connector of an automobile air-conditioner pipe is simple.
Description
Technical field
The utility model relates to automotive air-conditioning system pipeline technical field, particularly relates to the male connection of a kind of car air conditioner pipeline.
Background technique
At present, the male connection of automotive air-conditioning system pipeline is all adopted aluminium soldering to connect and is formed, and adopts the indexs such as intensity, tightness and wear resistance of the automotive air-conditioning system pipeline male connection of Type of Welding can not satisfy the product performance index requirement.Because reducing, can occur during welding rosin joint through its strength of materials plasticity after the weld heating, aluminum alloy influence material hardness reduction after tightness, the weld heating.Adopt Type of Welding processing tube pipeline connector also can increase labor intensity simultaneously, waste gas occurs, be unfavorable for defectives such as product surface processing.
Summary of the invention
The utility model has solved car air conditioner pipeline male connection intensity, tightness and wear resistance problem, has simplified the pipeline processing.
The technological scheme that its technical problem that solves the utility model adopts is: the male connection of described a kind of car air conditioner pipeline, form by metal threaded tube head and metal tube body component, it is characterized in that: metal threaded tube head is inserted in presswork in the enlarging of metal body.
The utility model beneficial effect is: adopt metal threaded tube head to be inserted in metal body enlarging presswork and replaced the male connection of traditional welding pipeline, make the male connection of car air conditioner pipeline increase intensity, tightness and wear resistance, also make pipeline male connection processing become simple.
