Abstract

The invention belongs to the technical field of dies and provides an upper die of a hot-forging die with an internal cooling function and a cooling method thereof. The upper die comprises a forging assembly. The forging assembly comprises an upper die, a punch and a lower die matched with the upper die. The punch is fixedly connected to the upper die. The upper die also comprises a cooling assembly. The cooling assembly comprises an adjusting part and a punch. As a cooling pipe communicates to the inner side of the punch, a cooling liquid in the cooling pipe will flow into the punch, and the punch is cooled by the cooling liquid contained in the punch to achieve an internal cooling purpose. Secondly, when the adjusting part rotates, the bottom of the adjusting part shrinks and is separatedfrom the bottom of the punch to further open an opening in the bottom of the punch, so that the internal cooling liquid flows out to a position where the punch is in contact with a hot forging part to cool the connection of the punch and the hot forging part, and therefore, a condition that the punch and the hot forging part are bonded together for a long time is avoided.

Description

technical field [0001] The invention belongs to the technical field of dies, and in particular relates to an upper die of a hot forging die with internal cooling function and a cooling method thereof. Background technique [0002] The forging die is a die used in the forging process. The raw material is plastically deformed in the forging die under the action of external force, so as to obtain parts of the required shape and size. Forging dies can be divided into hot forging dies, warm forging dies and cold forging dies according to different forging temperatures. Hot forging molds can also be divided into hammer forging dies, screw press forging dies, mechanical press forging dies, flat forging dies and hydraulic press forging dies due to different equipment. In press die forging, it is necessary to design and process the mold base. In the process, billet (such as roll forging, cross wedge rolling) dies, trimming dies, punching dies, correction dies, cold precision dies, e...
