Description

Technical Field

[0001] The utility model belongs to the technical field of heat treatment, and in particular relates to a fastener heat treatment tool. Background Art

[0002] Bolts and nuts are parts that are screwed together for fastening. They are essential components for all manufacturing machinery. Usually, when processing bolts and nuts, in order to improve the structural strength of bolts and nuts, they are quenched. Quenching is a heat treatment process that heats steel to above the critical temperature, keeps it warm for a certain period of time, and then cools it at a rate greater than the critical cooling rate to obtain an unbalanced structure dominated by martensite (there are also ways to obtain bainite or maintain single-phase austenite as needed).

[0003] After searching, the Chinese utility model patent with application number CN202221076086.2 and authorization announcement number CN217377962U discloses "a high-strength bolt quenching device", including a bracket, a quenching cylinder is fixedly connected to the bottom of the inner wall of the bracket, a transmission mechanism is provided on the top of the inner wall of the quenching cylinder, a bearing mechanism is provided at the bottom of the transmission mechanism, a drain pipe is connected to the bottom of the right side of the outer surface of the quenching cylinder, a filter mechanism is provided at the end of the drain pipe away from the quenching cylinder, a connecting pipe is provided on the top of the filter mechanism, and the top of the connecting pipe passes through the top of the bracket and is connected to a cooling box. This application opens the valve on the surface of the drain pipe and starts the water pump. The water pump filters the quenching liquid in the inner cavity of the quenching cylinder through the filter mechanism, and then enters the inner cavity of the cooling box through the connecting pipe, and then the quenching liquid after being cooled by the refrigerator body can be discharged into the inner cavity of the quenching cylinder through the water pump, so that the quenching liquid can be effectively circulated and cooled, preventing the quenching liquid from heating up, and ensuring the subsequent bolt cooling effect;

[0004] When the device is used, the bolts to be processed need to be poured into the inner cavity of the net cylinder. Because the bolts still have a very high temperature before quenching, when pouring the bolts into the net cylinder, collisions will inevitably occur between the bolts. The more the number of bolts, the more collisions there are, the greater the impact, and the bolts are easily deformed.

[0005] In order to solve the above problems, this application proposes a fastener heat treatment tool.
