Technical Field
The invention relates to the field of quenching cooling of heat treatment, in particular to a beam tube device for changing the flow rate of a medium in an effective quenching area of a well type quenching tank.

In the quenching process, the cooling capacity of water or various quenching liquid and other mediums directly influences the mechanical properties of the quenched workpiece. The relative movement speed of the workpiece and the media such as water or various quenching liquids directly affects the cooling effect of the quenching part, and the faster the movement speed of the media is, the higher the performance of the workpiece after quenching is. For a quenching tank used for meeting the requirement that a shaft workpiece enters liquid in a vertical hanging mode (the axial direction is perpendicular to the liquid level), under the condition that the number of stirrers and the rotating speed of the stirrers are determined, the medium flow rate in an effective quenching area (the effective quenching cooling area refers to the working space size meeting the range of the medium flow rate, the medium turbulence degree and the medium temperature change range specified by the corresponding quenching cooling process) is directly determined by the diameter of an inner cylinder of the quenching tank, and the larger the diameter of the inner cylinder of the quenching tank is, the smaller the medium flow rate is; conversely, the smaller the diameter of the inner cylinder of the quenching tank, the greater the medium flow rate. The practical problem is that the inner cylinder diameter of the quenching tank is usually designed according to the maximum quench diameter, and the diameter of the daily quench is far smaller than the maximum quench diameter at the time of initial design, so that quench cooling can be performed in the quenching tank at the same flow rate regardless of the size and performance requirements.

The invention can improve the flow speed of the quenching medium near the surface of the quenching workpiece without changing the structure of the original quenching tank and the stirring system thereof or increasing the power of the stirrer, thereby achieving the purpose of improving the cooling speed. The clamp is arranged on the quenching part and quenched together with the quenching part. For quenching of cylindrical or shaft parts with small length and small diameter, the clamp disclosed by the invention is feasible, and for quenching and cooling of long shaft parts, the clamp disclosed by the invention is difficult to realize in operation.
