Description

Technical Field

[0001] The utility model relates to the technical field of stamping cooling devices, in particular to a stamping part high-efficiency blanking cooling device. Background Art

[0002] Hot stamping technology utilizes the principle of metal thermoplastic forming, which can achieve quenching heat treatment of sheet metal during forming, improve the forming performance of the material, and greatly expand the performance of high-strength and ultra-high-strength steel.

[0003] For example, the authorization announcement number "CN220005674U" is named as an efficient cooling device for automobile stamping parts. Although the water pump, water storage pipe, nozzle, water outlet pipe and guide pipe are set to facilitate cooling of the stamping parts, compared with the cooling device that only cools down by fans, it still exists. The existing efficient cooling device for automobile stamping parts uses multiple nozzles to spray cold water on the conveyed stamping parts for cooling. However, the surface temperature of the stamping parts that have just been stamped will be very high and the stamping parts are made of hard metal. Therefore, the stamping parts under high temperature will be cooled. The stamping parts are easily quenched when they are directly washed by cold water, causing the temperature of the high-temperature stamping machine to drop rapidly and thus produce internal cracks. Not only that, the nozzles for spraying water cooling are also independently set at the top of the cooling device. Therefore, some parts of the stamping parts will be directly washed by the water flow and the cooling speed will be fast. However, some parts of the stamping parts with larger volume will be difficult to be directly washed by the water flow, and the cooling speed will be slow. Therefore, a temperature difference is generated during the cooling process of the stamping parts, making the stamping parts easy to deform and bend, which ultimately leads to a decrease in the quality of stamping parts produced by the existing high-efficiency unloading cooling device for automobile stamping parts.

[0004] At the same time, the existing automobile stamping parts high-efficiency unloading cooling device adopts two fans arranged on the inner wall of the cooling device to blow the cooled stamping parts to make them dry quickly. However, there is no barrier at the front end of the fan, so the water sprayed inside the cooling device is easy to splash everywhere, and the splashing water enters the inside of the fan blades. Over time, it is easy to cause the metal parts inside the fan to rust and age, thereby affecting the speed of drying the moisture of the stamping parts, and thus affecting the use effect of the automobile stamping parts high-efficiency unloading cooling device.
