Description

Technical Field

[0001] The utility model relates to the technical field of nut processing, in particular to a nut processing annealing furnace. Background Art

[0002] A nut is a cap that is screwed together with a bolt or a screw to tighten the nut. Annealing is required during nut processing. Annealing is a metal heat treatment process that refers to slowly heating the metal to a certain temperature, keeping it for a sufficient time, and then cooling it at an appropriate rate. The purpose is to reduce hardness and improve machinability; eliminate residual stress, stabilize size, reduce deformation and crack tendency; refine grains, adjust structure, and eliminate structural defects. To be precise, annealing is a heat treatment process for materials, including metal materials and non-metallic materials.

[0003] In the prior art, a Chinese utility model with publication number CN218989317U discloses a nut processing annealing furnace, which includes a base, a transmission mechanism for driving the nut to flip so that the nut is heated more fully and annealed more fully, and a limiting mechanism for limiting the device to facilitate the unloading of the nut after annealing.

[0004] In the above technology, hot air is input into the annealing furnace body through the air outlet pipe and the diverter pipe, so that the nuts are fully heated and annealed. After the processing is completed, the motor is started to drive the rotating shaft to rotate, so that the nuts are driven by the rotating blades to be discharged through the discharge frame. However, when discharging, it is impossible to ensure that all the processed nuts can be rotated out of the filter cartridge by rotating the rotating blades alone, which will cause the nuts to be left in the filter cartridge, thereby resulting in a waste of raw materials and an increase in production costs.
