Feeding box

Abstract

The invention discloses a feeding box. The feeding box comprises a feeding box body, a rotary stirring assembly arranged in the feeding box body and a powder feeding pipeline, and the feeding box body is provided with a powder containing inner cavity and a discharging opening; and the rotary stirring assembly comprises a driving part and a rotary stirring part, a lower side flat end face is arranged on the lower part of the feeding box body, a machining table is provided with a powder material containing position, and the lower side flat end face is attached to the surface of the machining table and slides along the surface of the machining table, so that powder in the powder containing inner cavity evenly falls to the powder material containing position. When the feeding box slides along the surface of the machining table, the driving part can drive the rotary stirring part to rotate so that powder in the powder containing inner cavity can be in a loose state, and the situation that a vacuum state is formed during powder filling due to the structural problem is avoided; and meanwhile, blocky powder can be scattered, powder falling is more uniform, and the problem that the yield is reduced is solved.

Description

technical field [0001] The invention relates to the field of stamping machines, in particular to a feeding box. Background technique [0002] At present, stamping presses are widely used in national production. Compared with traditional mechanical processing, stamping technology saves materials and energy, has high efficiency, does not require high technical requirements for operators, and can make mechanical processing through various mold applications. These advantages of products cannot be achieved, so its use is more and more extensive. [0003] But, there is following defect in existing feeding box: [0004] 1. The feeding box on the market needs to move back and forth on the processing table when feeding, so that the powder material falls into the cavity of the middle mold. The powder material will appear lumpy inside the feeding box. If the lump powder falls as a whole, it will cause the middle The powder material in the mold cavity has a high local density, resulti...

AI Technical Summary

Problems solved by technology

[0004] 1. The feeding box on the market needs to move back and forth on the processing table when feeding, so that the powder material falls into the cavity of the middle mold. The powder material will appear lumpy inside the feeding box. If the lump powder falls as a whole, it will cause the middle The powder material in the mold cavity has a high local density, resulting in defective products;

[0005] 2. The feeding box on the market needs to move back and forth on the processing table when feeding, so that the powder material falls into the cavity of the middle mold. After filling, there will be a difference in the left and right flatness of the upper surface of the material, and the powder density of the entire cavity of the middle mold Make it uneven and reduce the yield of the product
