Description

Technical Field

[0001] The utility model belongs to the technical field of brazing diamond tool manufacturing, and more specifically, relates to a feeding device for a brazing furnace. Background Art

[0002] In the field of brazed diamond tool manufacturing, the commonly used equipment is the vacuum brazing furnace. After the semi-finished diamond tools are placed in the furnace, the furnace door is closed, and the products are heated according to certain procedures and processes. After they are taken out of the furnace, the finished brazed diamond tools can be obtained. Due to the large variety of brazed diamond tools, complex specifications and diverse structures, the related fixtures and tooling are diverse, and these products are placed in the same furnace at the same time most of the time. In addition, due to the variable position of the fixtures and the placement space, there is usually no material frame when vacuum brazing diamond tools, which puts higher requirements on the placement and transportation of the products. The transportation device supporting the traditional vacuum brazing furnace is generally a material frame and a hydraulic forklift structure, and some are equipped with an electric forklift structure.

[0003] A Chinese patent with publication number CN209877645U discloses a feeding structure for a metal heat treatment brazing furnace, including a moving platform, a cavity is provided in the moving platform, two threaded columns are symmetrically provided in the cavity, and the upper ends of the two threaded columns extend to the upper end of the moving platform, a driving mechanism is fixedly connected to the inner top wall of the cavity, and the driving mechanism is connected to the two threaded columns, the upper ends of the two threaded columns are commonly fixedly connected to a support plate, and the upper end of the support plate is slidably connected to a discharge plate. A plurality of legs are symmetrically fixedly connected to the lower end of the moving platform. In summary, the utility model has a stable structure, simple operation, scientific and reasonable design, short production cycle, and can be conveniently adjusted according to the orientation of brazing furnaces of different heights, so that the brazing furnace can be conveniently fed.

[0004] However, due to the particularity of the aforementioned brazed diamond tools, the feeding structure still adopts a moving wheel structure, which leads to a decrease in the stability of the feeding. This structure cannot meet the needs well. Not only is there a large vibration during transportation, and the product is easy to fall, but manual operation is often difficult. In addition, the overall loading and unloading is also difficult, time-consuming and has certain safety risks (the workpieces out of the furnace often have a furnace temperature of about 100 to 200 degrees, and there is a risk of scalding).
