It provides foundry companies with advanced foundry equipment and necessary technical support to improve production efficiency and casting quality to adapt to the development of the times. The management of advanced casting equipment can ensure the stable operation of the equipment, increase the operating life of the equipment, and ensure the safe and efficient operation of the entire casting shop, thereby casting high-quality castings.

1. Composition of casting equipment
Casting equipment is divided into production lines and stand-alone equipment. The casting equipment of the production line has diversified structural characteristics. For example, in the sand processing production line, there are essential differences in the structure of vibration equipment such as shakeout machines, vibration conveying equipment, feeders, boiling cooling beds, and separation equipment such as suspended magnetic separators and air separators. In the casting production, the material transportation equipment such as belt conveyors, bucket elevators, etc. belong to the category of casting equipment. In the stand-alone equipment, it is mainly used for various binder sand mixing equipment, and it has a wide range of applications in core molding, testing, dust removal, heat treatment, and coating.
Under the influence of environmental protection awareness, the environmental protection requirements of dust removal and exhaust emission equipment in foundry equipment are becoming more and more stringent. On the basis of requiring its filtration and purification accuracy, it is necessary to reduce its noise as much as possible. In addition, under the awareness of energy saving, the application of natural gas to casting equipment is also an improvement method.

2. The particularity of casting equipment:
2.1 Dust persists
In the work of foundry equipment, the treatment of old sand and new sand will generate a lot of dust. Some dust fall off, binder film, particles, and residual paint after combustion will be distributed to the environment during the transmission of castings. Although there are certain requirements for casting equipment Dust removal equipment, but cannot achieve complete dust control. Dust accumulates in the gaps of the casting equipment and remains in the production environment, which has a serious impact on the normal operation of the staff and the casting equipment. Long-term development can easily shorten the service life of the casting equipment and cause work. Personnel lung disease occurred.
2.2 High temperature
It is necessary to change the physical shape of iron parts and steel parts in the casting work. The temperature of the molten iron should be ≥ 1300℃, and the temperature in the furnace for the heat treatment process of castings should be kept at 1100℃ for a long time. The table surface of the sand shaker is in direct contact with the high temperature sand (300°C). The vibrating motor''''s operating temperature is as high as 300°C. Even on the conveyor of the sand processing production line, the sand temperature is also 100°C. The casting equipment generally has high temperature and must have high strength. The high temperature resistance can ensure the stable operation of the equipment.
2.3 Frequent noise
Most casting equipment will produce loud noises. For example, shake-out machines, compact molding machines and start-up equipment, etc., often generate a lot of noise and energy during pneumatic operation. Pneumatic equipment reversing the exhaust pipe will produce great noise, up to 70~90dB.
2.4 Destructive
The casting work requires strong pressure and power from the equipment. Most of the equipment is destructive equipment. The production process of the equipment is also the process of its own service life. For example, the vibration crusher crushes the sand masses, and the process of the sand masses colliding with each other in the equipment frame is also a kind of damage to the equipment itself. Vibration conveying and pneumatic conveying pipelines will have a certain degree of grinding during transportation, and long-term transportation will aggravate the failure of the pipeline.
The characteristics of long-term dust, high temperature, frequent noise, and high destructiveness of foundry equipment have caused a heavy burden on equipment management. In the formulation of equipment management measures, the specific work of equipment must be fully considered, and corresponding management measures must be put forward in a targeted manner. For example, consider scientific management measures in terms of equipment dust prevention, noise prevention, and shock absorption. In casting production, changes in resin sand castings will cause changes in sand-to-iron ratio and affect the actual working conditions of casting equipment. For example, a decrease in the ratio of sand to iron will result in an increase in sand temperature and affect the normal operation of sand processing equipment. It will aggravate the wear effect of the vulnerable parts of the equipment and shorten the service life of the equipment.

3. Suggestions for equipment management in foundry workshops
3.1 Requirements for corresponding personnel
3.11 Foundry equipment operator: The operator is the main person responsible for equipment management, and the professionalism of the operator should be strengthened. Let them fully understand the operating specifications. The "Three Goods, Four Meetings, and Five Requirements" are deeply integrated into the on-the-job training of operators, and pre-job training is carried out in accordance with the "Equipment Manual" and the prescribed operating system before on-the-job training. , The operating specifications are passed to the operators. Cultivate the operator''''s sense of responsibility, let them realize the importance of their own work, establish equipment operation logs, record whether the equipment inspection is normal every day, solve and record the problems that can be solved in time, and notify them in time if there are no problems or serious problems The maintenance department repairs the equipment. In addition, the operator participates in the in-depth study of the equipment, achieves a "proficient job", has a high degree of proficiency in the operation of their own equipment, understands the performance of the casting equipment, deepens the understanding of the maintenance work, and has a foreseeable understanding of the equipment at work Maintenance, reduce the risk of serious failure.
Through rigorous pre-job training, operators are engaged in actual operations, setting up main and deputy positions, allowing newly appointed personnel to engage in deputy post operations, work under the guidance of experienced personnel, and work independently after having certain work experience. It is necessary to strengthen the emphasis on equipment operation, the operators pay attention to their own work, and have a sense of responsibility and sacredness in their own work, and provide a strong guarantee for high-quality casting production with standardized operations.
3.12 Equipment maintenance personnel: Equipment maintenance personnel are one of the guarantees for maintaining the stable development of casting equipment. For the reasonable maintenance of equipment, problems must be quickly judged and resolved in a standardized manner. Pay attention to the operation and maintenance of casting equipment during the inspection, and use preventive methods to solve equipment failures to ensure stable casting production. Design scientific preventive measures for foundry equipment failures that occurred in history, pay attention to wiping and reasonable operation of equipment in equipment maintenance, cherish the use of equipment, and reduce equipment failures.
Foundry enterprises must deepen the professional maintenance awareness of maintenance personnel, even if the fault is small, they must use standardized tools for maintenance after the casting equipment is completely stopped. Deepen the importance of casting equipment maintenance personnel to the inspection work. Carelessness is strictly prohibited during the inspection, and the problem of hidden safety hazards in the equipment is quickly solved without delay.
In casting production, pay attention to training all-round maintenance personnel, and on this basis, divide the work area of the maintenance personnel, assign specific work responsibilities to each person, improve the enthusiasm of the maintenance personnel, evaluate the number of equipment shutdowns and the probability of completeness, and strengthen management. Establish a performance appraisal system, give necessary bonuses and verbal praise to maintenance personnel with outstanding work, give appropriate economic penalties and report criticism to maintenance personnel who make mistakes in their work, and build a high-quality professional casting equipment maintenance team.
3.13 Foundry equipment management personnel: Foundry equipment management personnel should recognize their own responsibilities, recognize that the stable operation of casting equipment can promote the efficient development of casting production, and recognize the serious obstacles to casting production caused by the failure of casting equipment. Deepen the analysis and supervision of casting equipment in its own management work, combine the maintenance, maintenance and troubleshooting of casting equipment, establish a sound management system, and realize efficient management. Due to the peculiarities of the foundry industry, the casting production line has a harsh production line environment, which poses a serious threat to the management of casting equipment and affects the enthusiasm of management personnel. Therefore, it is necessary to strengthen the self-learning of management personnel and cultivate their strong professionalism, professional quality and hard work spirit.
In addition, the casting equipment management personnel should take advantage of their own technical knowledge, give full play to the advantages of the casting equipment, and maximize the use of equipment to reduce the work pressure of the staff, optimize the use of equipment, and reduce the probability of failure. Managers should invest sufficient manpower, material resources and financial resources in the prevention of failures, and take scientific preventive measures to prevent equipment failures and avoid serious economic losses to casting production after failures occur.

3.2 Production line casting equipment management
3.21 File creation. According to different casting equipment, set up corresponding archive files to fully integrate equipment purchase, management, maintenance and other work. For example, the equipment procurement contract, technical agreement, production process flow chart, operation specifications, equipment details, maintenance instructions, etc. are established as casting equipment files for later work needs. In addition, the production process flow chart, equipment operation specifications, and maintenance instructions are backed up and hung in an obvious position of the casting equipment to provide powerful help for standardized operation and daily maintenance.
Stand-alone file creation. The establishment of a single machine file is a detailed description of the file of the foundry equipment. The model, details, and qualification certificates of the equipment engine, reducer, operation center and other equipment are formed into a detailed single machine file. With the support of the file system catalog of the casting equipment, it is divided into the corresponding casting In the equipment file.
Create an inspection record form. In accordance with the requirements of casting production, set up regular inspection record tables for key parts of the equipment, record the operating status of the equipment in real time, realize real-time supervision of the wear-prone parts and other trouble-prone parts, and discover possible equipment failures in time. For example, establish regular inspection record forms for shake-out machines, reclaimers, sand mixers, and material-liquid systems, record equipment failures and the number of maintenance in a timely manner, and discover and optimize equipment defects in time to ensure stable development of casting production.
Replace the wearing parts in time after passing regular inspections. For example, the breakage of the grid plate of the crusher will cause the sand mass to flow into the next process, affecting the normal casting. Check the grid plate in time, and feedback in time when problems are found.
3.22 Optimize the casting process. Under the influence of the development of the times, more and more high-tech applications are applied to the casting production. The corresponding casting enterprises must optimize and update the casting equipment to further optimize the casting process. When the process that can be omitted is found, timely adjustment is made to reduce unnecessary The production process caused cost waste, adapt to the development of the times.

To sum up, in the analysis of equipment management in the foundry workshop, we must first understand the composition of the foundry equipment and the particularity of the foundry equipment, and put forward some optimization suggestions for the equipment management of the foundry workshop according to the particularity of the foundry equipment. In terms of personnel, optimize the casting equipment operators, The functions of equipment maintenance personnel and management personnel, and in the management of production line casting equipment, optimize the equipment management of all links, realize the comprehensive development of casting workshop equipment, and promote the stable development of casting production.
