Reinforcing technology of blower fan blade inner edging die

The invention discloses a reinforcing technology of a blower fan blade inner edging die. According to the technology disclosed in the invention, a prior blower fan blade inner edging laying technology is added with an inner edging reinforcing step by arranging an inner edging reinforcing die on inner wall of a blade leading edge in a lower die. Shape of the inner edging reinforcing die is corresponded with that of the inner wall of the blade leading edge, and the two can be tightly combined. Iron wires are arranged on combination spot of the inner edging reinforcing die and the inner wall of the blade leading edge. When the inner edging is laid, the inner edging reinforcing die can be tensioned through the iron wires, so that a glass fiber cloth, which is the inner edging, laid on exterior of an inner edging die is tightly bonded with the inner wall of the blade leading edge through resin and an adhesive, etc.
