Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and more specifically, to a cooling and quenching tank for the production of machined parts. Background Technology

[0002] Quenching is a heat treatment process. For steel, quenching involves heating the steel to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), holding it at that temperature for a period of time to achieve complete or partial austenitization, and then rapidly cooling it at a rate greater than the critical cooling rate to below Ms (or isothermally near Ms) to induce a martensitic (or bainitic) transformation. Quenching is also commonly used to describe solution treatment or heat treatment processes involving rapid cooling in materials such as aluminum alloys, copper alloys, titanium alloys, and tempered glass.

[0003] The multi-purpose quenching tank integrating online and offline quenching disclosed in application number CN202321541597.1 is also an increasingly mature technology. This multi-purpose quenching tank, which integrates online and offline quenching, relates to the field of heat treatment. The multi-purpose quenching tank includes a Π-shaped quenching tank body, which consists of an online quenching tank, an overflow tank, and offline quenching tanks connected to one end of each end of the online and overflow tanks, respectively. The bottom wall of the online quenching tank is inclined, and its depth gradually increases as it approaches the offline quenching tank. The bottom wall of the online quenching tank near the offline quenching tank is recessed to form a sedimentation tank. Multiple water inlet pipes are connected to the bottom wall of the online quenching tank away from the offline quenching tank, and these water inlet pipes are connected to a water supply pipe. The overflow tank is connected to at least one pumping pipe, which is connected to a return water pump. The multi-purpose quenching tank provided in this application, which integrates online and offline quenching, can meet various quenching methods such as online and offline quenching, and can collect and settle the oxide precipitates from online quenching for easy cleaning.

[0004] Based on this, we agree with the advantages of the aforementioned products, but the following drawbacks still exist:

[0005] In general, the batch quenching scheme for turned parts is quite difficult in terms of technical means, and it is difficult to load the parts, which makes it somewhat difficult to cool down the turned parts. The placement and cooling scheme of the turned parts in the quenching stage is quite complicated and difficult to achieve cooling. Utility Model Content
