Abstract

The invention discloses a long pipe inner wall quenching device which comprises a supporting frame. An installation plate is fixed to the upper end of the supporting frame and provided with a supporting base. A sliding rod is arranged in the supporting base. A first annular fixing frame is fixed to the outer wall at the left end of the sliding rod. Spray heads are evenly arranged on the outer ring of the first annular fixing frame. A threaded hole is formed in the left end of the sliding rod. A threaded rod is fixed in the threaded hole in a threaded connection manner. A second annular fixing frame is fixed to the left end of the threaded rod. An intermediate-frequency heater is fixed to the outer ring of the second annular fixing frame. The long pipe inner wall quenching device has the beneficial effects of being reasonable in structural design, low in production and manufacturing cost, convenient to use and the like, achieves quenching for the inner walls of pipes, and ensures the quenching quality of the inner walls of the pipes; and meanwhile the threaded rod design is adopted, and the distance between the intermediate-frequency heater and the spray heads can be adjusted according to technological requirements, so that the quenching efficiency of the device is improved, the production cost is saved, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of quenching equipment, in particular to a long tube inner wall quenching device. Background technique [0002] In the mechanical field, the quenching process is a very widely used treatment method. The quenching process refers to heating a certain metal material to a certain temperature and maintaining it for a certain period of time to change its alloy structure. Its main purpose is to improve the mechanical properties of the alloy and increase its corrosion resistance. With the development of the times, pipes are used more and more in hydraulic, electric power, mining and other industries, and the processing technology of pipes is also diverse. In my country, metal pipes are commonly used, but metal pipes have disadvantages such as low hardness, poor corrosion resistance, and short life. Therefore, it is necessary to quench the metal pipes to improve the hardness and toughness of the pipes. Contents of...
