Problems solved by technology

In the existing quenching equipment, the oil in the quenching oil pool is pumped into the cooling pool for cooling, and the time for the oil in the cooling pool to cool to 80°C-120°C is relatively long, which affects the continuous progress of the quenching process , it will inevitably lead to waste of furnace temperature and increase of cost

Embodiment Construction

[0020] Such as figure 1 Shown is the connection diagram of the existing quenching equipment for steel balls used as abrasives, and the existing equipment will be described in detail below in conjunction with the accompanying drawings. There is a quenching oil pool 5 on the ground. The quenching oil pool 5 is filled with cooling oil 6. The cooling oil 6 is used to cool the steel balls heated to a certain temperature to improve the strength, hardness, wear resistance and Toughness etc. A vertically placed oil cylinder 1 is arranged above the quenching oil pool 5, and the cylinder barrel of the oil cylinder 1 is fixed on a support in the workshop; during work, the piston rod of the oil cylinder 1 performs telescopic movement in the vertical direction. A metal disc 2 is fixedly installed on the free end of the piston rod of the oil cylinder 1, and four through holes are evenly arranged on the disc 2 along the circumference, and a steel wire rope 3 is respectively fixed in the fou...

Abstract

The invention relates to a temperature control coolant oil cycle apparatus used for quenching, which comprises cooling pipelines, a water pump and a cooling tower, and is characterized in that at least one cooling pipeline immersed in the coolant oil is paved at the bottom of an inner cavity of a quenching oil pond, and two ends of the cooling pipeline, the water pump and the cooling tower are communicated through the pipelines and form a loop for conveying cooling water. The coolant oil cycle apparatus is capable of cooling the coolant oil through circular flow of water, which can substitute the process that the coolant oil is directly placed in the cooling pond for air-cooled cooling in the prior art, the coolant oil can be rapidly decreased to the required temperature, the cooling efficiency is increased; the circular flow of water cools the coolant oil in real time without transfer of the coolant oil in the cooling pond for cooling, quenching work can be continuously carried out, so that the resource waste caused by continuous heating of fire temperature in cooling time of the coolant oil can be avoided.

Description

technical field [0001] The invention relates to a quenching process, in particular to a cooling device for an oil cooling medium for quenching. Background technique [0002] Quenching is a metal heat treatment process in which a metal workpiece is heated to an appropriate temperature and maintained for a period of time, and then immersed in a quenching medium for rapid cooling. The purpose of quenching is to transform supercooled austenite into martensite or bainite to obtain martensite or bainite structure, and then temper at different temperatures to greatly improve the hardness, strength and wear resistance of the steel. properties, mild fatigue and toughness, so as to meet the different requirements of various mechanical parts and tools. In the quenching process of steel balls for abrasives, the temperature of the cooling oil in the quenching oil pool needs to be controlled between 80°C–120°C to ensure a good quenching effect; red-hot steel balls are continuously thrown...
