Cooling water circulation system of thermal forming production line for automobile

Abstract

The invention provides a cooling water circulation system of a thermal forming production line for an automobile. The cooling water circulation system comprises a process cooling water system and a cold source system, wherein the process cooling water system comprises a pressing machine cooling water system, a die cooling water system, a power storage water tank and a water collector which is connected with the pressing machine cooling water system and the die cooling water system respectively; two cold water outlets are formed in one side of the power storage water tank, and a cold water inlet and a hot water outlet are formed in the other side of the power storage water tank; the two cold water outlets of the power storage water tank are respectively connected with the pressing machine cooling water system and the die cooling water system; a heat exchanger is arranged between the power storage water tank and the cold source system, and the cold water inlet of the power storage water tank is connected with a water outlet of the cold source system through the heat exchanger; the hot water outlet of the power storage water tank is connected with a water inlet of the cold source system through the heat exchanger. The cooling water circulation system can regulate the temperature of water in the system finely, and increase the finished product ratio. Under the condition of lower external environment temperature, a water chiller does not need to be used for cooling, so that the energy consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of cooling water circulation systems, and in particular relates to a cooling water circulation system of an automobile thermoforming production line. Background technique [0002] With the continuous improvement of the safety performance of automobiles, hot stamping one-time forming equipment for automobile steel plates has emerged as the times require. The essential difference between this new technology and the traditional hot stamping technology is that it is not through air cooling, but through the arrangement of the cooling circuit, and through the cooling water mold to achieve rapid quenching and cooling of the parts, and then obtain ultra-high-strength stamping parts. However, the refrigerating equipment of the existing cooling system continuously performs refrigeration work, which consumes a lot of power, and in the cold winter weather, the refrigerating equipment also performs high-power work, which...

AI Technical Summary

Problems solved by technology

However, the refrigerating equipment of the existing cooling system continuously performs refrigeration work, which consumes a lot of power, and in the cold winter weather, the refrigerating equipment also performs high-power work, which greatly consumes the working life of the refrigerating equipment, and the finished product is very expensive.

The water temperature adjustment in the existing cooling system is not precise enough, which leads to the product prone to mold condensation, and the product yield is relatively low
