Embodiment Construction

[0022] Taking the typical part of the large deformation rotary body, the expanded rolling blank of the inner and outer rings of SKF railway vehicle bearings as an example, the liquid immersion cooling device and its process proposed by the present invention are explained:

[0023] Liquid immersion cooling device for expanding and rolling blanks of inner and outer rings of SKF railway vehicle bearings (such as figure 2 shown), including the workpiece, the mandrel, the rotary wheel, and the circulating fluid chamber, in which the circulating liquid cavity is filled with cooling liquid, the workpiece, the mandrel, and the rotary wheel are immersed in the cooling liquid, and the liquid circulation inlet and outlet are set on one side of the cavity . The mold consists of a mandrel (that is, the inner wheel) and a rotary wheel (that is, the outer wheel). The liquid circulation inlet and outlet (ie, 7 cooling liquid inlets and 8 high temperature liquid outlets) provided on one side...

Abstract

The invention provides a rotational part, in particular to a liquid immersion cooling device for plastic forming of large and medium rotational parts and a process of the liquid immersion cooling device. The liquid immersion cooling device comprises a rotational part plastic forming device, a cavity body for plastic forming of the rotational part, and a refrigerating device, wherein a cooling liquid is filled in the cavity body; the rotational part plastic forming device and the rotational part are immersed in the cooling liquid; and the cavity body is communicated with the refrigerating device. The heating step in a forming process is cancelled and a subsequent processing step is simplified, so that product quality is effectively improved and production cost is reduced. Cold forming power of the large and medium rotational parts is certainly more than heat forming power, but the electric heating step is cancelled, so that a comprehensive energy consumption index of cold forming is far lower than an energy index of heat forming. Therefore, the liquid immersion cooling device also has typical characteristics of energy saving and emission reduction.

Description

technical field [0001] The invention belongs to the field of metal plastic forming, and relates to a liquid immersion cooling device for plastic forming processing of rotary parts and its technology, which is suitable for plastic forming processes in cold states (room temperature) such as rolling and spinning of large and medium-sized rotary metal parts. Cooling of deformation heat. Background technique [0002] When the rotary metal parts are subjected to rotary forming at room temperature, under the continuous constraint of the external force through the mold, lattice slip and dislocation will occur inside the workpiece, and heat will be released to the outside, causing the workpiece to heat up sharply. If the temperature rise caused by deformation heat is not effectively suppressed in time, it will cause damage to the working mold, and the cooling process of the workpiece after processing will also produce a certain degree of deformation. When the machining deformation i...
