Three types of cement mixer maintenance and repair Due to the need for concrete mixing, compared to general engineering vehicles, its structure has its special features. The mixer has six additional systems: Therefore, in addition to the maintenance of automobile engines, chassis, and other parts, the concrete mixer truck must also be well maintained for concrete tanks (agitator drums), inlet and outlet port cleaning, and agitating maintenance drives. 1. After each delivery of concrete is completed, timely cleaning of the tank body and hopper can reduce the agglomeration phenomenon of the concrete on the three-piece sleeve, reduce the equipment downtime, and reduce the intensity of maintenance work.

2. Stagger the peak of production, timely perform partial repair welding on hoppers, eight-charging troughs, and unloading hoppers, and install tank openings to reduce leakage leakage caused by the equipment in the process of entering and discharging materials, and to ensure equipment integrity. Based on the maximum guarantee of the equipment tidy and improve the company's image.
3. In the off-season end of production, reasonably arrange the time to focus on cleaning the concrete inside the mixing tank body, check the wearing condition of the three-pieces, and replace the three-pieces with the heavily worn ones in time to ensure the continuous operation of the mixing truck in the next operation. . To increase equipment maintenance work is to reduce the intensity of equipment maintenance. Specifically, engineering machinery can be divided into the following three categories in terms of maintenance methods:
1, after the repair. The failure of the construction machinery to be repaired before use is referred to as post-mortem maintenance. When the loss of stop production is small, it is more economical to adopt this type of maintenance when only adjusting or replacing the wearing parts can eliminate the failure.
2, preventive maintenance. From a preventive point of view, preventive maintenance and repair before a failure occurs is called preventive maintenance. Preventive maintenance includes three aspects of routine maintenance, equipment inspection and preventive repair. Routine maintenance can prevent or postpone the deterioration of construction machinery, check or monitor the construction machinery periodically or irregularly, detect signs of failure and repair in time, and avoid sudden stoppage losses.
3, improve maintenance. This method is based on the results of fault recording and condition monitoring. While repairing the fault site, it improves the mechanical performance or local structure of the project to overcome the inherent deficiency of the construction machinery, improve the equipment performance, and reduce the failure, but it cannot compensate for the construction machinery. Invisible wear. Due to the special nature of the concrete industry and the shortage of company's equipment, in the current situation, our company's mixing stations often use this type of maintenance after repair. Judging from the effect of equipment operation, the attendance rate of agitated vehicles has been greatly ensured, and the cost of equipment maintenance has been greatly reduced. However, the maintenance of this equipment also has its limitations. In the early stages of equipment operation, the use of such equipment management methods is like killing chickens and eggs. Short-term costs are reduced at the cost of long-term maintenance costs. From another perspective, the concept of capital flow is considered in equipment assets. The initial small-scale maintenance of equipment or equipment maintenance costs a small amount of maintenance costs in the early period, in return for long-term stable output of the equipment; on the other hand, , Equipment with "disease" operation, the cost of investment in safety is unpredictable, and the maintenance of equipment at this cost is worth discussing. If only from the equipment point of view, taking preventive maintenance seems to be the most reasonable method, but the equipment in the production of relatively busy, to adopt such a method, it is worthwhile to think whether the cost increase it brings is worthwhile. Taking into account both the maintenance costs and the opportunity cost of the equipment is an aspect that must be considered in the management of concrete mixer trucks. Regular and regular monitoring of equipment operation status, feedback on equipment usage, timely and reasonable maintenance of the equipment, flexible use of three maintenance methods to find the balance of the equipment attendance rate and the lowest maintenance cost, maximize the company's profits.
In the manufacturing industry, forming molds play a vital role. It is a kind of mold used to manufacture various shapes and sizes, and is widely used in automotive, medical, electronics and other fields. This paper will discuss the definition and basic concept of forming die, application field, development process and future trend.
First, the definition and basic concepts of molding die
Molding die is a kind of mold used to manufacture various shapes and sizes, mainly through pressure, temperature and chemical reactions to transform raw materials into products in the desired shape. Molding die can be divided into many types according to different manufacturing needs, such as die casting die, injection mold, forging die and so on. In the manufacturing industry, molding molds have the advantages of high efficiency, accuracy and low cost, and are indispensable production tools.
Second, the application field of forming die
1. Automotive field: A large number of molding molds are needed in the automotive manufacturing process, such as doors, seats, engine parts, etc. Forming molds can produce automotive parts that meet the requirements in an efficient and accurate manner, thereby improving production efficiency and reducing costs.
2. Medical field: The manufacturing process of medical devices also needs to use molding molds, such as syringes, artificial joints, etc. The molding mold can produce devices that meet medical standards in a high-precision manufacturing method, thereby improving the quality of medical care.
3. Electronic field: The manufacture of components such as the shell and internal structure of electronic products also requires the use of forming molds. The molding die can produce the required electronic product parts in an efficient and low-cost way, thus reducing the cost of electronic products.
Third, the development of molding die
The development process of forming die can be divided into two stages: traditional die and modern die. The traditional mold is mainly made by hand, and the accuracy and efficiency are relatively low. With the continuous progress of science and technology, modern molds gradually adopt mechanized and automated production methods, which greatly improve production efficiency and accuracy. At the same time, with the continuous development of computer technology, modern mold design has gradually adopted computer-aided design software for design, further improving the accuracy and efficiency of mold design.
Fourth, the future trend of molding die
With the continuous development of science and technology, the future trend of forming die will develop in the direction of digital, intelligent and green.
1. Digitalization: Digital technology can realize the precision and automation of mold design and improve the efficiency and accuracy of mold design. At the same time, digital technology can also realize the comprehensive monitoring and management of the mold production process, improve production efficiency and quality.
2. Intelligent: Intelligent technology can realize the automatic production and online monitoring of molds, improve production efficiency and product quality. At the same time, intelligent technology can also achieve predictive maintenance and fault warning of molds, reducing production costs and maintenance costs.
3. Green: With the continuous improvement of environmental awareness, green production has become an inevitable trend in manufacturing. In the future, the production of molding molds will pay more attention to environmental protection and energy saving, such as the use of environmentally friendly materials, energy-saving design and production processes to reduce environmental pollution and resource waste.
In short, forming die as an important production tool in the manufacturing industry, its development trend will directly affect the development direction of the manufacturing industry. In the future, with the continuous development of science and technology and the changing needs of society, the molding die will continue to innovate and develop, injecting new impetus into the development of the manufacturing industry.
