A metal workpiece quenching equipment that can quickly extract mist

Abstract

The invention discloses a metal workpiece quenching device capable of quickly extracting mist, comprising a quenching box, the inner wall in the middle of the quenching box is fixedly connected with a limit ring, and the middle position of the inner wall at the bottom of the quenching box is fixedly connected with a support rod. The top of the support bar is fixedly connected with a support block. When the present invention is in use, the quenching liquid is poured into the bottom of the quenching box through the guide bucket, the density of the floating block is lower than that of the quenching liquid, and it rises together with the liquid level, and the addition of the quenching liquid is stopped after the floating block is stuck at the bottom of the limit ring. During the rising of the floating block, the lifting rod slides along the inner wall of the sleeve to limit the path of the floating block to avoid shaking. The workpiece to be quenched is inserted into the quenching box through the guide bucket and the intubation tube, and the quenching liquid rises into the intubation tube Inside, as the volume of the workpiece immersed in the quenching liquid increases, the liquid level inside the cannula rises synchronously, fully immersing the workpiece, improving the utilization rate of the quenching liquid, and reducing the quenching cost.

Description

technical field [0001] The invention relates to the technical field of metal processing, in particular to a metal workpiece quenching device capable of rapidly extracting mist. Background technique [0002] At present, quenching is to heat the steel above the critical temperature, hold it for a certain period of time, and then cool it at a rate greater than the critical cooling rate, so as to obtain an unbalanced structure mainly composed of martensite (there is also a possibility of obtaining bainite or maintaining single-phase austenitic structure according to needs). Tensile body) a heat treatment process. Quenching is the most widely used process method in steel heat treatment process. [0003] In the quenching and cooling stage, the workpiece after quenching and heat preservation needs to be immersed in the cooling liquid. The cooling liquid is greatly lost in the process of contacting the high-temperature workpiece, which increases the quenching cost of the workpiece,...

Problems solved by technology

[0003] In the quenching and cooling stage, the workpiece after quenching and heat preservation needs to be immersed in the cooling liquid. The cooling liquid is greatly lost in the process of contacting the high-temperature workpiece, which increases the quenching cost of the workpiece, wastes production resources, and burdens the processing of the workpiece. It is necessary to design a metal workpiece quenching equipment that can quickly extract the mist to solve the above problems
