How to improve the domestic construction machinery industry coating quality? |
Public date:2016-11-9 Hits：4848 |
China's construction machinery (drive axle assembly) industry, the coating production line is basically the late 80s of last century built, after 10 years of use, coupled with poor management, the current domestic construction machinery manufacturers coating production line has been unable to meet most of the production demand. This situation has caused China's construction machinery products in performance, quality and the international level of the gap gradually narrowed, but the appearance of quality and foreign products, the gap is great. Faced with increasingly fierce market competition, the experts proposed to improve the quality of the appearance of domestic construction machinery a few suggestions:
Increasing Utilization Rate of Coating Equipment and Increasing Technological Layout
The current domestic construction machinery coating technology development, automotive pump to maintain the coating engineering and use the smallest cost of painting to achieve the maximum function, we must explore to meet the social requirements of high resource utilization, to eliminate or prevent environmental pollution Coating and coating process.
There are many kinds of parts, many shapes, many dead spots and big difference in size. The users have different conditions for the use of the products, and the corrosion resistance and decoration of the whole machine and parts and components are different. Sexual requirements are different. These are the coating technology put forward higher requirements, but the general principle is that the rational use of energy, pay attention to energy saving, environmental protection, safety and health and fire; the use of advanced and mature process equipment, rational distribution, logistics unobstructed. Follow the above principles, can be divided into machine machine coating machine line, large line and small pieces of line.
Machine coating line using the ground chain conveyor machine form, the ground requires wear-resistant surface. The use of hydraulic lift to open the car to the car, transported by the ground chain (overweight vehicles using their own way of transport). Cleaning room with stainless steel structure, the upper part of both sides of the exhaust device, the water gas from the workshop, after cleaning the workpiece with compressed air drying or self-dry; spray paint spray room selection, winter air conditioning gas heating Wind; drying room using gas heating, the formation of hot air convection cycle, the organic waste gas combustion through the combustion chamber.
Large painting line using self-hoist intermittent delivery of the workpiece, belt conveyor parts by the cycle of operation, the cycle of two laps to complete the primer and coating production; spray room with water spin spray booth, the device paint mist collection High rate, the workers operating environment. The indoor temperature of the painting room can be up to more than 15 degrees. The drying room adopts the gas direct heating to form the hot air circulating convection mode. The organic waste gases generated in the drying room pass through the combustion chamber deal with.
Small pieces of coating lines using ordinary hanging conveyor conveying parts, production line speed by 2m / min, speed adjustable. The use of hanging crane auxiliary upper and lower parts, spray paint room with water curtain paint room, which includes an independent ventilation system, the use of gas heating in winter for the wind, circulating pool to add paint mist coagulant, easy to clean up paint residue, The use of gas heating, the chamber at both ends of the hot air curtain seal to prevent heat loss; mobile car washing machine in the coating drying room with hidden bridge gas drying room, heat insulation (heat flow flat) Effect is good, beautiful and generous. The organic waste gas produced in the drying chamber is combusted by the combustion chamber, and the exhaust gas in the leveling chamber is purified by an activated carbon adsorption device.
Painting quality requirements focus on management assurance
There are many factors that affect the film quality, but there are: people, materials, equipment, quality, on-site, etc., but these factors are inseparable with the management. Improve the rules and regulations for the majority of domestic enterprises in terms of coating technology is more positive.
Personnel management: the operator's sense of responsibility, the operator's skill is to affect the painting quality of human factors. First of all, we must strengthen the training of the operator (such as through learning, knowledge contest, technology contest and other methods), improve the operator skills. Second, the operator should be posts, appointment, responsibility. In addition to the establishment of rewards and punishments assessment system to improve the operator's consciousness, sense of responsibility, quality training, to play the initiative of staff is a practical way of personnel management. |
