Rapid furnace leaving device for bent pipe fittings

Abstract

The invention relates to a rapid furnace leaving device for bent pipe fittings. The rapid furnace leaving device comprises a stand column, a swing arm bracket, a lifting mechanism for driving the swing arm bracket to rise and fall and a rotating mechanism for driving the swing arm bracket to rotate; the swing arm bracket is arranged on the stand column in a sleeving manner, the lifting mechanism is used for driving the swing arm bracket to move up and down, and the rotating mechanism is used for driving the lifting mechanism and the swing arm bracket to rotate; and the tail end of the swing arm bracket is used for supporting a bracket of the bent pipe fittings. Rising and falling motions of the swing arm bracket are completed through a lifting cylinder, material taking is achieved in the rising process of the swing arm bracket, then the intermediate stand column serves as a rotating shaft to rotate, one bent pipe fitting on the swing arm bracket is moved to a designated position through a rotating cylinder, and discharging is achieved in the falling process of the lifting cylinder; and then the swing arm bracket is rotated back to the reclaiming position in a furnace through the rotating cylinder for waiting for one next bent pipe fitting to be in place, and one cycle is completed. The rapid furnace leaving device has the advantages of reducing heat loss before bent pipe spraying and being long in service life, suitable for bent pipes in various specifications and the like.

Description

technical field [0001] The invention relates to a drill pipe tapping device, in particular to a quick tapping device for bent pipe fittings. Background technique [0002] With the development of economy and technology, higher requirements are put forward for the anti-corrosion industry. To achieve the purpose of long-term protection in harsh environments, increasing the thickness of the anti-corrosion layer is the most basic condition. [0003] The coating is eroded by corrosive media, which will cause physical dissolution and swelling. The media penetrates and diffuses in the coating, resulting in bubbling, peeling and cracking of the coating. When the media penetrates into the protected metal surface, it will react with the metal and generate corrosion products. , Volume expansion, coating blistering, peeling, coating loses anti-corrosion effect. This kind of damage is extremely easy to occur in conventional thin coatings. It is proved from theory and experiment that the...
