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

Abstract

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.

Description

technical field [0001] The invention belongs to the production field of special equipment for auto parts, and in particular relates to a high-speed straightening and cutting process and equipment for aluminum flat tubes of automobile air conditioners, which can make aluminum flat tube coils into straight materials of the same size. Background technique [0002] With the active adoption of advanced technology of parallel flow circulation in the automotive air-conditioning industry, the heat dissipation efficiency of aluminum water tanks and radiators has been greatly improved, so they are fully utilized on the condensers and evaporators of automotive air-conditioning systems. It is an inevitable trend of development that the intercooler is made of all-aluminum materials. [0003] Aluminum flat tube is an essential material for the manufacture of automobile air-conditioning condensers and evaporators. During production, it is usually necessary to straighten and cut the disc-sh...

AI Technical Summary

Problems solved by technology

But in the past, it was made by manual or semi-automatic equipment, the running speed is slow, the cutting accuracy is not high, and the error is more than 1mm, and after the aluminum flat tube is cut off, it needs to be moderately flattened on another special equipment. Closing, in this case, it is imminent to design and produce a special equipment that can complete the straightening, leveling, closing, cutting, breaking and other processes of aluminum flat tube coils on the same machine. The high-speed straightening and cutting machine for automotive air-conditioning aluminum flat tubes is the special equipment for realizing these functions.
