A kind of air cooling device for heat treatment workpiece

Abstract

The invention discloses an air cooling device for heat treatment of a workpiece, which comprises a support device and a plurality of air blowing devices arranged on the support device, wherein the lower end of the support device is provided with a bearing part for bearing a workpiece; the air blowing devices for cooling the workpiece are arranged above the bearing part; the upper end of the support device is provided with a first cross beam; and the air blowing devices are arranged on the first cross beam in a movable manner. The air cooling device for heat treatment of a workpiece is simple in structure, convenient to manufacture and uniform in workpiece cooling, and enhances the cooling quality, thereby enhancing the quality of the workpiece, and reducing the deformation and rejection of the workpiece. Thus, the air cooling device has favorable popularization value.

Description

Technical field [0001] The invention relates to the cooling of a workpiece after heating in a heat treatment furnace, in particular to an air cooling device for heat treatment of the workpiece. Background technique [0002] The heat treatment furnace is an industrial furnace that performs various metal heat treatments on metal workpieces. After heat treatment of various workpieces, they need to be cooled before the next operation process can be carried out. At present, the cooling of heat treatment workpieces generally adopts transverse air cooling. That is, the fan and the heat-treated workpiece are in the same horizontal plane, and the fan is used to cool the transverse wind blown out of the heat-treated workpiece. However, this cooling method has the following problems: ①The lateral blowing makes the side of the heat-treated workpiece facing the fan cool faster, and The side facing away from the fan cools more slowly. Due to the uneven cooling, the internal structure hardness ...

Problems solved by technology

[0002] The heat treatment furnace is an industrial furnace for performing various metal heat treatments on metal workpieces. After the heat treatment of various workpieces, it needs to be cooled before the next operation process. At present, the cooling of heat treated workpieces generally adopts the method of horizontal air cooling. That is to say, the fan and the heat treatment workpiece are at the same level, and the fan is used to cool the heat treatment workpiece with the horizontal wind blown out, but this cooling method has the following problems: ① The lateral air blowing makes the side of the heat treatment workpiece facing the fan cool faster, while The side facing away from the fan cools slowly. Due to uneven cooling, the internal structure hardness of the heat-treated workpiece is inconsistent during the cooling process, which affects the quality of the heat-treated workpiece; ②It takes a long time for the fan to blow horizontally for cooling; When it is small, the horizontal blowing will cause the heat treatment workpiece to shake during the cooling process, which will easily cause the heat treatment workpiece to tilt to one side and fall down, causing damage to the workpiece
