Problems solved by technology

[0003] In the prior art, the positioning device generally uses heat-resistant steel or ceramic materials. During the long-term heat treatment process, if heat-resistant steel is used for positioning, it will cause certain deformation or damage to the heat-resistant steel, and the heat-resistant steel Deformation will also lead to poor positioning accuracy; if ceramic materials are used, due to the poor toughness of ceramic materials, repeated use at high temperatures will cause the positioning device to break. Therefore, the above two positioning devices cannot well meet the heat treatment process. Positioning requirements for structural parts

Abstract

The invention provides a cooling positioning pin. The cooling positioning pin comprises a first connecting port (10), a second connecting port (20) and an internal connecting hole, wherein the first connecting port (10) is located at a first position of the cooling positioning pin, the second connecting port (20) is located at a second position of the cooling positioning pin, and the internal connecting hole extends inside the cooling positioning pin and is respectively connected with the first connecting port (10) and the second connecting port (20). The cooling positioning pin can effectively improve the positioning performance of a positioning device on a structural part to be processed in the hot treatment process, and prolongs the service life of the positioning device.

Description

Technical field [0001] The present invention relates to cooling technology in the heat treatment process, and in particular to a cooling positioning pin. Background technique [0002] In the field of thermal processing treatment, the overall heat treatment process of small and medium-sized structural parts with holes is often involved. In the heat treatment process, due to technological requirements, the heat treatment processing structural parts need to be positioned accordingly, so a positioning device is required to meet the heat treatment process The positioning of structural parts in the process is required. [0003] In the prior art, the positioning device generally uses heat-resistant steel or ceramic materials. In the long-term heat treatment process, if heat-resistant steel is used for positioning, it will cause certain deformation or damage to the heat-resistant steel. Deformation will also lead to poor positioning accuracy; if ceramic materials are used, due to the poor...
