High-strength steel plate quenching machining device

Abstract

The invention discloses a high-strength steel plate quenching machining device which comprises a box body, a workbench, a support, a conveying roller, a purifying box and a rotary quenching mechanism.The quenching work of a steel plate can be more sufficient through the rotary quenching mechanism, and the quenching work efficiency of the quenched steel plate is improved. A water spraying ring isdriven to rotate through a rotating gear and a transmission gear arranged in the rotary quenching mechanism, then nozzles arranged on the inner side of the water spraying ring perform rotary quenchingwork on the steel plate sufficiently and uniformly, and the steel plate can be quenched at the same time through the nozzles which are annularly arranged at equal intervals, so that the phenomenon that the quenching work of the steel plate is delayed is avoided, and the quenching work quality is guaranteed. Purification treatment is conducted on the steel plate through the purifying box, so thatthe situation that smoke is exhausted and affect the body health of workers is avoided.

Description

technical field [0001] The invention relates to the technical field of iron and steel manufacturing equipment, in particular to a high-strength steel plate quenching processing device. Background technique [0002] Quenching, a heat treatment process for metal and glass; steel quenching is to heat the steel to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), and keep it warm for a period of time to make it all or partly austenitic Body 1, and then quickly cooled to below Ms (or isothermal near Ms) at a cooling rate greater than the critical cooling rate to perform a heat treatment process for martensite (or bainite) transformation; usually aluminum alloys, copper alloys, titanium alloys The solid solution treatment of tempered glass and other materials or the heat treatment process with rapid cooling process is called quenching. The purpose of quenching is to transform supercooled austenite into martensite or bainite to ob...

Problems solved by technology

[0003] For the quenching work of the steel plate, the prior art usually treats the steel plate from the heat treatment furnace and then it is quenched. For the quenching work, it is usually simply provided with a number of nozzles for water spray quenching. In this process, a On the one hand, the quenching work of the steel plate is not enough or the quenching is slow, which will affect the work efficiency, reduce the quality of the quenching work, and affect the quality of the steel plate manufacturing work. On the other hand, the smoke generated during the quenching process cannot be handled well. The health of personnel will be affected, for this reason, the present invention proposes a high-strength steel plate quenching processing device to solve the above-mentioned problems
