This "world free day" on September 22 is not new. The "World Car Free Day" campaign was initiated in France in 1998 and entered China in 2001. It has been carried out for 10 years in succession. On the day of car free day, colorful activities are very eye-catching. Leading cadres of many cities and cities take the lead in bus or bicycle commuting to work. Some cities delineate car-free areas and use various means of propaganda. It is widely advertised that the idea of ​​having a car-free day and green travel has gradually become popular.
"Car free day" is important, but only one day a year. Even if the forms of activity are re-innovation and the contents are enriched, their influence will be difficult to sustain, and some temporary measures can hardly change the public's car habits. The latest statistics show that as of the end of August 2011, the number of motor vehicles in the country reached 219 million, of which the number of motor vehicles exceeded 100 million for the first time. Faced with such rapid and large-scale automobile consumption growth, in addition to enhancing the city’s scientific planning capabilities, traffic management standards, and vigorously developing public transportation, it is also necessary to promote green travel and raise public awareness of environmental protection and energy conservation. Compared with the bustling “Car Free Day†activities, it is more important to use the “Car Free Day†as an opportunity to spread and guide the awareness and responsibility of car civilization, and let civilized travel and green travel become the conscious actions of every citizen.
The cultivation of automotive civilization requires that every traffic participant realizes his/her civic responsibility. Civilization means understanding, tolerance, and tolerance in transportation. In the use of the car, consciously abide by the traffic order, all the way, and their responsibility, is the basic requirements of the automotive civilization. Traffic jams are a common problem in cities, especially in big cities. They are not unique to our cities, nor can they be cured overnight. Civilized travel can increase traffic efficiency to a certain extent, alleviate the anxiety caused by traffic jams, and reduce congestion. Traffic accident. For example, in some cities where the automobile civilization is more mature, the traffic is also congested at the peak hours, but everyone is quiet and patiently queue up, no one whistle whistling, no one garrishes, passing in order, fair and orderly. Such peace and order is civilization. In some cities with narrow streets and inconvenient parking, citizens will voluntarily choose new energy vehicles that are small in size, small in size, and more energy-efficient and environmentally-friendly. They have less environmental damage, travel more smoothly, and parking is easier. This choice is rational and civilized.
Car civilization also includes calm and pragmatic use of cars. Having a car does not mean that the car is the only travel tool. The travel of all traffic participants should be a system that suits local conditions, rationality, and hierarchy, without having to rely too much on certain travel tools. In areas with flat terrain, there are naturally more cyclists; in hilly and mountain areas, vigorously advocating cycling does not produce significant results. For another example, walking distance within 15 minutes, you can consider walking; within 3 kilometers, you can consider riding a bicycle or bus, subway; in a long distance, public transport and inconvenient places, driving a private car Also reasonable. At the same time, it is also a simple and effective method of civilized travel to improve the utilization rate of transportation through the use of joint-property, co-tenancy and other methods.
Chen Zhuo’s “big Ben†was paralyzed. His environmental protection show did not seem to have ended. After the annual "Car Free Day", the topic of automotive civilization will long be with us.
Stamping is a manufacturing process that involves applying pressure to a material to deform it into a desired shape or size. There are various types of stamping processes utilized in the industry, each with its unique set of advantages and disadvantages. In this article, we will describe some of the most common types of stamping processes.
Blanking: Blankings are flat pieces of sheet metal that have been precisely cut and punched out from larger sheets of metal. Blanking is a process used to produce these flat pieces, and is ideal for producing large quantities of uniform, flat parts.
Coining: Coining is a stamping process used to create impressively flat and precise features - often used in creating coins or bearing seals.
Drawing: Drawing involves pulling a flat piece of metal through a die with a punch tool to form it into a three-dimensional shape. This process is commonly used in the creation of products such as automobile fenders, cans, and ship hulls.
Embossing: Embossing is the process of applying raised designs or patterns to a flat piece of metal by impressing the metal with a die. This process is popularly used in the production of decorations and signage.
Piercing: Piercing is the process of punching or drilling holes in a metal sheet. It is widely used in creating products such as luggage tags, name plates, and metal attachments.
Blanking and forming: Blanking and forming involve using a single die to create a part that has a variety of features, both flat and formed. It is a highly efficient process for creating complex parts.
Overall, stamping is a versatile manufacturing process that plays a crucial role in the production of a wide range of metal parts and components. By understanding the different types of stamping processes, manufacturers can select the most suitable process for producing high-quality parts in an efficient and cost-effective manner.
