Wind impeller blade progressive die and processing method

Abstract

The invention discloses a wind impeller blade progressive die and a machining method. The wind impeller blade progressive die comprises a lower die assembly and an upper die assembly. The lower die assembly comprises a first punching part, a second punching part and a third punching part which are sequentially arranged. A first punching hole is formed in the first punching part, and second punching holes and third punching holes are formed in the second punching part. A blanking hole is formed in the third punching part. The upper die assembly comprises a first male die, second male dies, third male dies and a fourth male die. The second male dies and the third male dies are arranged in the circumferential direction in a spaced manner around the same center line. The radius of the first male die, the distance between the axis lines of the second male dies and the center line, the distance between the axis lines of the third male dies and the center line and the radius of the fourth male die are sequentially increased. Due to the cooperation of the set of upper die assembly and lower die assembly, machining can be completed, the cost is relatively low, and meanwhile the strength of the die is relatively high.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a progressive die for a wind impeller blade and a processing method thereof. Background technique [0002] With the improvement of people's living standards, the application of air conditioners is becoming more and more extensive, but the circulation of indoor and outdoor air will lead to an increase in the power consumption of the air conditioner, while reducing the temperature adjustment effect of the air conditioner. For this reason, an air curtain has appeared, which can separate the indoor and outdoor air by blowing without affecting people's access. [0003] The blowing of the air curtain blades mainly depends on the rotation of the blades. The blades of the wind blades are stamped and formed by a mold. There are many process holes on the blades of the wind blades, and the structure is relatively complicated. The cost of production is high when using a single-process ...

[0003] The blowing of the air curtain blades mainly depends on the rotation of the blades. The blades of the wind blades are stamped and formed by a mold. There are many process holes on the blades of the wind blades, and the structure is relatively complicated. The cost of production is high when using a single-process mold. The strength is not high, none of which meet the market demand
