Abstract

The invention provides cooling equipment for use in machining of GH4169 turbine disk forgings, which can solve the problems of low cooling rate, instable product quality and the like in the conventional GH4169 ally forging cooling process. The cooling equipment comprises a cooling water tank, wherein the bottom of the cooling water tank is provided with a rack. The cooling equipment is characterized by also comprising a cooling machine, wherein the cooling machine is connected with the cooling water tank through an external circulating pipe; and the cooling water tank is also connected and provided with an internal circulation system.

Description

technical field [0001] The invention relates to the technical field of direct aging of GH4169 alloy forgings, in particular to cooling equipment for processing GH4169 turbine disc forgings. Background technique [0002] GH4169 turbine disc forgings belong to aviation and aerospace engine discs. The existing direct aging method of GH4169 turbine disc forgings is to put the turbine disc die forging directly into the cooling water tank for aging treatment. The cooling rate of the forgings is low and the product quality is low. It is difficult to control; in order to speed up the rapid cooling of forgings in the water tank, there are also hanging forgings in the water tank and shaking continuously, but during the shaking process, the cooling rate of each part of the forging is likely to be uneven, resulting in large internal stress and uneven structure of the forging In addition, the cooling water tank it uses is a cooling water tank for ordinary heat treatment. Although its coo...
