Description

Technical Field

[0001] The utility model relates to automatic feeding equipment, in particular to an automatic feeding mechanism for a continuous mesh belt tempering furnace. Background Art

[0002] The drive shaft of a car's constant velocity universal joint consists of a fixed end joint, an intermediate shaft, and a movable end joint. The fixed end joint is directly connected to the car's wheel hub, while the movable end joint is directly connected to the engine's differential. The engine's power is transmitted to the wheel through the differential, movable end joint, intermediate shaft, fixed end joint, and wheel hub, thereby driving the wheel's rotation. The fixed end joint primarily consists of an outer ring, a retainer, an inner ring, and steel balls; the movable end joint primarily consists of an outer sleeve, a retainer, an inner sleeve, and steel balls. Both the outer ring and the outer sleeve undergo tempering after medium-frequency quenching and cleaning to eliminate internal stress, reduce brittleness, stabilize the structure, and adjust mechanical properties. Tempering is generally performed in a continuous mesh belt tempering furnace to meet single-piece flow requirements. Since tempering typically takes two hours, using a single row of workpieces for tempering would result in an excessively long furnace and excessive floor space. Using multiple rows of workpieces for tempering and manual loading would be labor-intensive and inefficient. In the past, tempering outer rings or jackets required manual loading of multiple rows of workpieces. This method was labor-intensive, inefficient, and impacted delivery schedules. Therefore, a mechanism for efficient loading of outer rings or jackets was urgently needed at the processing site. Summary of the Invention
