Description

Technical Field

[0001] The invention relates to the technical field of oil cooler manufacturing, in particular to sheet metal stamping and forming equipment for oil cooler manufacturing. Background Art

[0002] Oil cooler is also called oil chiller. According to the principle of refrigeration system, low-temperature and low-pressure liquid refrigerant exchanges heat with surrounding water in the evaporator. The evaporator absorbs the heat of the oil and evaporates into low-temperature and low-pressure gas. The temperature of the refrigerant does not change during the evaporation process. The low-temperature and low-pressure gaseous refrigerant enters the compressor, is compressed by the compressor, and is compressed into a high-temperature and high-pressure gaseous state. Then it enters the condenser and exchanges heat with the indoor medium in the condenser. Part of the heat of the high-temperature and high-pressure gaseous state is absorbed by the medium, the temperature of the medium rises, and the refrigerant releases heat to become a high-temperature and high-pressure liquid. The temperature of the condenser process remains unchanged, and then it enters the expansion valve for throttling. Throttling is a process of rapid cooling. The refrigerant becomes a low-temperature and low-pressure liquid. The refrigerant after this process enters the evaporator again. The evaporator performs heat exchange and evaporation, thereby realizing the entire process of the refrigeration system. This cycle is continuous, and the oil can be continuously cooled. Sheet metal has the characteristics of light weight, high strength, conductivity, low cost, and good performance in large-scale mass production. It has been widely used in electronic appliances, communications, automotive industry, medical equipment and other fields. For example, in computer cases, mobile phones, and MP3s, sheet metal is an indispensable component. With the increasing application of sheet metal, the design of sheet metal parts has become a very important part of the product development process. Mechanical engineers must be proficient in the design skills of sheet metal parts so that the designed sheet metal can meet the requirements of product function and appearance, and make the stamping die manufacturing simple and low-cost.

[0003] For example, the patent document with the announcement number CN 220346992 U discloses sheet metal frame stamping forming equipment, including: a stamping mechanism and an operating table for supporting the stamping mechanism; the stamping mechanism at least includes a mounting plate, and the mounting plate is lifted and installed on the top surface of the operating table; the bottom of the mounting plate is frame-mounted with multiple detachable punch mechanisms, and when the mounting plate descends, it drives the multiple punch mechanisms to punch downward synchronously, and the bottom of the mounting plate is provided with multiple mounting holes in a rectangular array. When stamping sheet metal frame parts of different sizes, the utility model can realize synchronous punching processing of the sheet metal frame parts through multiple detachable punch mechanisms. When punching, the mounting plate drives multiple punch mechanisms to press down on the sheet metal frame parts at the same time, so that the equipment can punch the sheet metal frame parts at the same time.
