Disclosure of Invention
The design purpose is as follows: the defects in the background technology are avoided, and the fan air inlet spinning machine and the air inlet spinning forming method capable of completing forming of air inlets with different calibers of a fan without a forming die are designed.
The design scheme is as follows: in order to achieve the above design objective. The invention has the structural design that: 1. the manual arc pressing mechanism is controlled to lift by a manual arc pressing lifting mechanism, and is one of the technical characteristics of the invention. The purpose of this design is: the manual arc pressing mechanism is composed of a top wheel and a pressing wheel, the top wheel is a fixed wheel, the pressing wheel is a driving wheel, and the manual arc pressing mechanism is an arc dynamic forming die for the air inlet edge of the fan, and aims to force the air inlet edge of the fan to be gradually pressed into an arc-shaped opening by the top wheel and the pressing wheel in the rotating process. In order to achieve the purpose, the manual arc pressing lifting mechanism controls the manual arc pressing mechanism to ascend or descend through a hand wheel, a ball screw, a guide wheel and a sliding sleeve sleeved on a guide rail, so that the manual arc pressing lifting mechanism is matched with the opening edge of the air inlet of the processed fan, namely, a die opening between a top wheel and a pressing wheel is opposite to an oil opening of the pressed air inlet. 2. The two technical characteristics of the invention are that the pair of transmission rollers are respectively sleeved on the transmission shaft, and the pair of transmission rollers sleeved on the transmission shaft can move along the transmission shaft and can be driven by the transmission shaft to rotate. The purpose of this design is: because the wheel face of a pair of drive rolls is opened has many annular grooves, this annular groove has two effects: firstly, the air inlet of the fan to be processed is welded on the cover plate, when the cover plate is clamped in the annular grooves of the pair of transmission rollers, the annular grooves clamp (lock) the cover plate, because the movable push-pull plate positioned below the annular grooves of the pair of transmission rollers is positioned in the grooves in the transmission rollers in a clearance fit manner and does not influence the transmission of the transmission rollers, therefore, the moving push-pull plate can drive the transmission roller wheel to move along the transmission shaft under the action of the T-shaped screw rod and the translation hand wheel, so that the air inlet edge of the processed fan extends into an arc-shaped forming die formed by the top wheel and the pressing wheel, when the motor drives the gears on the two transmission shafts to synchronously rotate through the driving gear on the speed reducer, the transmission roller can be forced to rotate, and then the air inlet edge of the belt wheel fan rotates, and the air inlet edge of the fan is forced to be pressed into a required arc-shaped opening edge under the adjustment of the gap between the top wheel and the pinch roller opening die. 3. The design that the jacking and lifting column frame drives the jacking and lifting assembly to lift and the jacking and translation assembly can transversely move along the jacking and lifting assembly is the third technical characteristic of the invention. The purpose of this design is: according to Newton's third law F = -F, when a top wheel and a pinch roller in the arc pressing mechanism act on the edge of a pressed air inlet of a fan, huge reaction force can be generated, and the air inlet of the fan can be pressed into a required shape by an arc die orifice formed by the top wheel and the pinch roller under the driving of a transmission roller only when the reaction force is counteracted. Therefore, the design that the lifting assembly is propped against the lifting assembly to rise or fall under the driving of the long descending column frame can adapt to the die pressing arc forming of the air inlet openings of the fans with different diameters, and the jacking assembly is propped against the translation assembly to enable the processed air inlet openings to be propped against by the transverse movement of the lifting assembly, so that the reverse acting force generated when the air inlet openings of the fans are molded along the pressing die is offset. 4.
