Full-automatic double-station device for spraying paint on outer surfaces of cast iron pipes

Abstract

The invention relates to a full-automatic double-station device for spraying paint on the outer surfaces of cast iron pipes. A bracket is mounted on the ground. A guide rail is arranged at the upper part of the bracket. A paint spraying trolley and dust removing trolleys are mounted on the guide rail and can move along the guide rail. The paint spraying trolley is connected with the dust removing trolleys. Another guide rail used for allowing a primary tip trolley and a secondary tip trolley to travel is arranged in the middle of the bracket. Pneumatic devices are connected with the tail parts of the primary tip trolley and the secondary tip trolley. A trolley guide rail is arranged under the bracket. A pipe feeding and discharging stepping trolley is mounted on the trolley guide rail, and is connected with a stepping trolley cylinder and a duplex cylinder, which are mounted on the bracket. Automatic aligning devices are arranged in front of the bracket, are parallel to the bracket, and are connected with a pneumatic system. The full-automatic double-station device can be used for spraying paint on cast iron pipes which are 3 m long and have different external diameters, and adopts automatic control, the labor condition and the operation environment are improved, the labor intensity of workers is effectively reduced, the paint sprayed cast iron pipe is high in quality, and high in precision, and the working efficiency is improved effectively.

Description

Technical field [0001] The invention belongs to spraying equipment, and in particular relates to a full-automatic double-station cast iron pipe exterior paint spraying equipment applied on a centrifugal cast pipe production line. Background technique [0002] Paint outside the cast pipe is to spray paint on the outer surface of the cast iron pipe. Since cast iron pipes are mostly buried underground and exposed in the air, it is easy to cause the cast iron pipes to oxidize and reduce the service life of the cast iron pipes. [0003] The centrifugal cast pipe industry is a traditional manufacturing industry. For many years, various pipe casting plants have been using simple single-station external painting equipment with the old structure. Among them, the pipe inlet process, the pipe installation process and the pipe outlet process are all completed with manual assistance. Dust removal equipment. The thickness of the cast iron pipe sprayed by this equipment is uneven, the spraying q...

Since the application of cast iron pipes is mostly buried in the ground and exposed in the air, it is easy to cause oxidation of cast iron pipes and reduce the service life of cast iron pipes

[0003] The centrifugal casting pipe industry is a traditional manufacturing industry. For many years, the casting pipe factories have been using simple single-station external painting equipment with old structure. Dust removal equipment, the thickness of the cast iron pipe sprayed by this equipment is uneven, the spray quality is poor, the labor intensity of the workers is high, and the working environment is polluted, so that the safety and health of the operators are not guaranteed, the degree of automation is low, and the production efficiency is low.

[0004] With the increasing market demand for cast iron pipes and the continuous improvement of the strength index, corrosion resistance and smoothness of the surface treatment of cast iron pipes, ordinary manual painting and single-station painting equipment are increasingly unable to meet the needs of the market. , which brings many difficulties to the batch operation of the entire assembly line and seriously restricts the development of the enterprise. There is an urgent need to develop fully automatic multi-station painting equipment to meet the needs of the market.
