Description

Technical Field

[0001] The utility model relates to the technical field of metal heat treatment, in particular to a novel metal heat treatment cooling device. Background Art

[0002] Heat treatment refers to a metal hot processing process in which the material is heated, kept warm and cooled in the solid state to obtain the expected structure and properties, including annealing, normalizing, quenching, tempering, aging treatment, etc.

[0003] The workpiece needs to be cooled after heating. The cooling method of the workpiece plays a very important role in improving the strength of the workpiece. Usually, the workpiece taken out of the heating furnace is placed in the air to cool itself, but due to the poor air circulation under natural conditions, the heat cannot be transported out, resulting in uneven cooling of the product, resulting in excessive internal stress of the product. At the same time, natural cooling takes longer, resulting in low production efficiency; the main method currently used is to use a blower to assist in removing the heat from the surface of the workpiece, but because the blower blows air in one direction, the workpiece cannot be cooled evenly. In this way, the hot air on the other side of the blocked workpiece is not easy to flow, causing the hot air and cold air to meet and condense into water droplets attached to the surface of the workpiece, greatly reducing the quality of the workpiece.

[0004] To this end, we propose a new type of metal heat treatment cooling device. Utility Model Content

[0005] The purpose of the utility model is to provide a novel metal heat treatment cooling device to solve the problems raised in the above background technology.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The novel metal heat treatment cooling device places the metal parts to be cooled on a rotating table by arranging a blowing plate and an air suction plate, and drives the rotating shaft and the rotating table to rotate through the driving gear and the driven gear, so that the metal parts rotate. At the same time, the blower and the air exhauster work. The blower conveys air to the blowing pipe through the air supply pipe and sprays air from the through hole to cool the rotating metal parts. The air exhauster sucks out the high-temperature hot air from the through hole of the air suction plate through the return air pipe, so that the air flow inside the protective cover keeps flowing to cool the metal parts, thereby accelerating the air flow on the surface of the metal parts and accelerating the cooling speed of the metal parts. The metal parts rotate at a uniform speed with the rotating table, so that the metal parts can be evenly cooled and the product quality is improved.

[0015] This novel metal heat treatment cooling device is equipped with a rotating shaft and an air guide groove inside the rotating table. The connecting pipe diverts the airflow in the air supply pipe to the rotating shaft, and after being dispersed by the air guide groove, the cooled airflow is sprayed on the bottom of the metal part through the air jet hole, so as to prevent the bottom of the metal part from cooling down too slowly, thereby affecting the uneven cooling of the metal part.
