Description

Technical Field

[0001] The utility model relates to the technical field of tempering furnaces, in particular to a tempering furnace used for heat treatment of metal parts surfaces. Background Art

[0002] Tempering furnace is an important equipment in heat treatment process, mainly used for tempering of metal materials. Tempering refers to the process of heating the quenched metal material to a certain temperature, keeping it for a period of time, and then cooling it at an appropriate speed (usually air cooling) to achieve the required mechanical properties. This process is crucial to improve the plasticity and toughness of the material, reduce or eliminate quenching stress, and prevent deformation and cracking of the workpiece.

[0003] When some existing tempering furnaces are in use, a carrier structure for hanging workpieces is provided inside them, but the workpieces need to be hung one by one, which is time-consuming and labor-intensive. The subsequent removal of the workpieces is also quite cumbersome, which is inconvenient for centralized tempering of large quantities of workpieces.

[0004] Therefore, it is necessary to invent a tempering furnace for surface heat treatment of metal parts to solve the above problems. Utility Model Content

[0008] Preferably, the number of the loading mechanisms is set to be multiple, and the multiple loading mechanisms are distributed in a linear array from top to bottom along the rotation axis.

[0009] The loading mechanisms are spaced at a certain height from each other to avoid collision between upper and lower workpieces.

[0010] Preferably, the number of support rods on each of the loading mechanisms is set to be multiple, and the multiple support rods are distributed on the outside of the fixing ring in a ring array.

[0011] The workpiece is suspended in a dispersed manner via multiple support rods.

[0012] Preferably, each of the support rods is provided with a plurality of receiving grooves, and the plurality of receiving grooves are distributed on the surface of the support rod in a linear array.

[0013] The storage groove is used to install the shift block and can store the shift block. After the shift block is stored, the surface of the support rod is in a smooth and unobstructed state.

[0014] Preferably, the shift block is whistle-shaped, and anti-slip patterns are provided on the surface of the shift block.

[0015] By standing the shift block upright, the workpieces can be separated, and the anti-slip pattern can prevent slipping when the shift block is turned over.

[0016] Preferably, one end of the support rod away from the fixing ring is threadedly connected to a limiting member, and two ends of the limiting member extend to two sides respectively.

[0022] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0023] 1. By arranging a flippable shifting block on the support rod of the loading mechanism, multiple workpieces can be pushed onto the support rod for hanging at one time after the shifting block is stored. The hanging operation is time-saving and labor-saving, and it is also very easy to pick up the workpieces later, which is convenient for centralized tempering treatment of large quantities of workpieces;
