Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment, and more specifically to a heat treatment device for cut wire shots. Background Art

[0002] Heat treatment refers to a metal thermal processing process in which the material is heated, kept warm and cooled in a solid state to obtain the expected structure and properties. The steel shots after forging workpieces or cut wire shots also need to be heat treated using heat treatment equipment during the production process. However, the commonly used heat treatment heating furnace is not easy to load and discharge due to the small number of steel shots. At the same time, adding steel shots into the heating furnace will cause steel shot accumulation, resulting in uneven heating temperature of the accumulated inner and outer steel shots, which will reduce the heat treatment quality.

[0003] For example, a heat treatment equipment disclosed in announcement number CN118582965A includes a heating furnace with a heating chamber inside, a furnace door for opening and closing the heating chamber of the heating furnace is provided at the right end of the heating furnace, a feeding rack is also provided at the right end of the heating furnace, the top surface of the feeding rack is tilted downward from left to right, and there is a clearance between the feeding rack and the furnace door, a discharge port with two ends passing through is provided in the middle of the furnace door, and a connecting support frame is also provided on the furnace door below the right end of the discharge port, and the top surface of the connecting support frame is arranged parallel to the top surface of the feeding rack.

[0004] It can be seen from the above-mentioned disclosed scheme that the bottom of the heating chamber inside the heating furnace is horizontal, which makes it difficult to automatically guide the heat-treated workpiece, and it is also inconvenient to enter with the heat-treated workpiece, which brings certain inconvenience to the user. At the same time, when heat-treating smaller spherical steel shots, the steel shots will pile up with each other, which may cause uneven heating temperatures of the external and internal steel shots during heating, reducing the quality of heat treatment.
