Description

Technical Field

[0001] The utility model relates to the technical field of forging cooling, in particular to a performance heat treatment cooling device for barrel-type forgings. Background Art

[0002] Forgings refer to workpieces or blanks obtained by forging and deforming metal billets. Forgings can be divided into cold forging, warm forging and hot forging according to the temperature of the billet during processing. Cold forging is generally processed at room temperature, and hot forging is processed at a temperature higher than the recrystallization temperature of the metal billet. The difference in the complexity of the geometric structure of forgings determines that their die forging process and die design are significantly different. Clarifying the structural type of forgings is a necessary prerequisite for process design.

[0003] For example, the patent document with the announcement number CN 217324205 U discloses a device for cooling the performance heat treatment of cylindrical forgings, which mainly relates to the technical field of cooling equipment. A device for cooling the performance heat treatment of cylindrical forgings includes a base, a first arc plate and a second arc plate are respectively connected to the base through corresponding displacement mechanisms, a first nozzle is fixedly installed in the first through hole, a main water inlet pipe is fixedly installed on the first connecting pipe, a second nozzle is fixedly installed in the second through hole, and the second nozzle located on the same second arc plate is connected through the corresponding second connecting pipe, a secondary water inlet pipe is fixedly installed on the second connecting pipe, and a drainage pipe is fixedly installed on one side of the base. The beneficial effect of the utility model is that when the device is in use, the workpiece can be directly sprayed with cold water through the first nozzle and the second nozzle to cool it down, so that the cold water can evenly contact the workpiece to ensure uniform performance of the workpiece, while avoiding deformation caused by different cooling speeds of different parts of the workpiece.

[0004] However, when this structure is used for heat treatment cooling of cylindrical forgings, it is often only possible to perform cooling processing operations on the outer wall of the cylindrical forgings inward. However, once the overall thickness of the cylindrical forgings is large, the cooling liquid is often unable to perform synchronous cooling operations inside and outside, affecting the final quality consistency inside and outside of the cylindrical forgings. At the same time, the equipment is unable to perform more efficient cooling and loading and unloading operations on cylindrical forgings and cannot meet daily use needs. Therefore, it is urgent to design a performance heat treatment cooling equipment for cylindrical forgings to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a cooling device for the performance heat treatment of cylindrical forgings, so as to solve the problem proposed in the above background technology that the existing structure can only perform cooling processing operations on the outer wall of the cylindrical forgings inward during the performance heat treatment cooling of the cylindrical forgings, but once the overall thickness of the cylindrical forgings is large, the cooling liquid often cannot perform synchronous cooling operations inside and outside, affecting the final quality consistency of the inside and outside of the cylindrical forgings. At the same time, the equipment cannot perform more efficient cooling and loading and unloading operations of the cylindrical forgings and cannot meet daily usage needs.

[0014] Preferably, both ends of the cooling outer cover and the cooling inner seat are sealed and connected.

[0015] Compared with the prior art, the beneficial effects of the utility model are:
