Agricultural machine casting quenching unit

Abstract

The invention discloses an agricultural machine casting quenching unit which comprises a water tank and a filter. A quenching chamber is arranged on one side of the interior of the water tank, an airdrying chamber is arranged on the other side of the interior of the water tank, an adjusting mechanism is vertically installed at the middle portion of the upper portion of the water tank, a top support is horizontally installed on one side of the upper portion of the adjusting mechanism, a lifting mechanism is installed on one side of the upper portion of the top support, one side of a straight rod is sleeved with an object containing basket in a sleeving manner, a circulation pump is arranged outside the side, close to the quenching chamber, of the water tank, a water inlet of the filter isconnected to the other end of a guide rail pipe, and a water outlet of the pressure water tank communicates with the quenching chamber through a guide pipe. According to the agricultural machine casting quenching unit, water is guided to the interior of the filter through a water guide pipe to be filtered and then conveyed into the pressure water tank for temporary storage, then the water is appropriately conveyed back to the interior of the quenching chamber for supplementing for internal water amount, water consumption is reduced, the water using efficiency is improved, and the environment is protected.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a quenching device for agricultural machinery castings. Background technique [0002] Quenching, a heat treatment process for metals and glass. The quenching of steel is to heat the steel to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), keep it warm for a period of time to make all or part of the austenite 1, and then cool it at a temperature greater than the critical cooling rate. Rapid cooling to below Ms (or isothermal near Ms) for martensite (or bainite) transformation heat treatment process. Castings for agricultural machinery must undergo quenching operations during production to improve performance. [0003] The existing quenching tank mechanism is to manually operate the castings into the storage basket, and then manually put the storage basket into the water tank for quenching, which is not conduciv...

AI Technical Summary

Problems solved by technology

[0003] The existing quenching tank mechanism is to manually operate the castings into the storage basket, and then manually put the storage basket into the water tank for quenching, which is not conducive to the quenching of the castings. At the same time, there is a lot of water in the storage basket just proposed, which is not conducive to the casting Post-processing, at the same time, the water used in the operation process has many internal impurities after repeated use, which affects the quality of the castings, requires multiple replacements, consumes a lot of water, and pollutes the environment with low water utilization efficiency
