High-speed straightening dimensioning blanking process and equipment for aluminum flat pipe of automobile air conditioner

The invention provides a high-speed straightening dimensioning blanking process and equipment for an aluminum flat pipe of an automobile air conditioner. The equipment consists of a driving material cutting frame, a straightening device, a servo feeding device, a servo online necking device, a dimensioning cutting device, a clamping tension fracture device, a material collecting table, a machine body and an electric control system, and is characterized in that the whole processes of disc material cutting, straightening, necking, tension fracture and automatic finished product collection can be realized on the same production equipment, all servo motors in the whole equipment are respectively controlled by a programmable controller so that the immediate synchronous movement of actions of all devices is ensured, and three actions of necking, cutting and clamping tension fracture of the aluminum flat pipe can be simultaneously completed on three different devices of the equipment. When the equipment is adopted, the forming precision of the finished products of the aluminum flat pipes can be improved by three times, and the operation efficiency of the equipment is improved by five times.
