Metal quenching device for metal heat treatment

Abstract

Disclosed is a metal quenching device for metal heat treatment. The metal quenching device for metal heat treatment comprises a cooling liquid tank, a first supporting table, a rotating shaft, a second supporting table, a roller, a mesh box, a mounting frame, a sealing plate, a protruding bar, a pull rope, a guide pulley and a round rod; the first supporting table is fixed to the corner of one side of the upper surface of the cooling liquid tank; the second supporting table is fixed to the side, away from the first supporting table, of the upper side face of the cooling liquid tank; the two ends of the rotating shaft are installed at the upper ends of the first supporting table and the second supporting table in a penetrating manner respectively; the middle of the rotating shaft is sleevedwith the roller, and the mesh box is fixed to the annular side face of the roller; the mounting frame is fixed to the end, away from the roller, of the mesh box, and the sealing plate is mounted in the mounting frame; the protruding bar is fixed to the middle of the side, close to the second supporting table, of the outer surface of the sealing plate, and the side, close to the first supporting table, of the outer surface of the protruding bar is connected with the pull rope; and the end, away from the protruding bar, of the pull rope is wound around the guide pulley, and the guide pulley sleeves the upper end of the round rod. The metal quenching device for metal heat treatment facilitates the one-time mass movement of small-size metal in the quenching process and effectively improves the working efficiency.

Description

technical field [0001] The invention relates to the field of metal heat treatment equipment, in particular to metal quenching equipment for metal heat treatment. Background technique [0002] Heat treatment refers to a metal thermal processing process in which materials are heated, kept warm and cooled in a solid state to obtain the desired structure and properties. Quenching is an important part of the heat treatment process. 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 (and also obtain bainite or maintain single-phase austenite according to needs). ) of a heat treatment process. Quenching is the most widely used process method in steel heat treatment process. The most common ones are water-cooled quenching, oil-cooled quenching, air-cooled quenching, etc. [0003] In actual use, i...

Problems solved by technology

[0003] In actual use, it is not convenient to transport and move a large amount of metals to the cooling liquid after heating. If the metals are moved one by one, the work efficiency will be low.
