Japanese cars have been impacted by the recent continuous recall of quality stability concepts

Recently, AQSIQ announced that due to the need to upgrade the electronic control unit (ECU) software, Honda Motor will recall 2.49 million vehicles worldwide, including Guangzhou Automobile Honda and Dongfeng Honda will start from August 8. A total of more than 760,000 cars were sold for the recall of the Accord, Odyssey and Sibo Rui.

Honda’s recall occurred at the moment when the Toyota’s “recall door” incident had not yet completely dissipated. This would not only make people question it: What happened to Japanese auto brand?

Reporter: How do you see the recall of Japanese brands?

Chen Wenkai: After Toyota recalled, Honda Motors also had several recalls, which was not the same as the previous impression that Japanese cars gave to consumers. Japanese cars have always given consumers the impression that there are fewer defects and quality. However, last year China's car recall ratio accounted for only 6.5%, far lower than the mature country car market. In 2010, the number of automakers recalled in the United States totaled nearly 20 million vehicles. In the same year, the United States sold only 11.5 million new cars. In other words, the number of cars recalled in the US market in 2010 was more than the number of new cars sold, so the recall culture in the Chinese market is not mature.

Cui Dongshu: Japanese car recall is a normal event. It is difficult to avoid the company's product design process. Judging from the recall itself, it is the company's responsible performance and gives the company the opportunity to make corrections. It cannot be explained by the number of recalls and scale that the quality of the car is problematic. More and more multinational car companies have also considered the Chinese market at the time of their recall. This is a process of progress. However, at present, domestic laws and regulations cannot keep up with the needs of the market, consumer awareness of rights protection is not high, and the cost of rights protection is high.

In addition, Toyota's "recall door" incident affected Honda Motors, Honda Motors has a stronger sense of risk and is more cautious about handling recalls.

Reporter: What kind of far-reaching impact will the global recall of the product bring to car dealers?

Cui Dongshu:
Product recalls will have a certain impact on the market, but it will not be great. In mature markets, the recall of car companies is a common thing. In a market where the automobile culture is not mature, consumers may think that the recall is a very serious matter. In fact, many hidden dangers in the recall will not be encountered by most consumers.

Chen Wenkai: To a certain extent, it will hurt the brand image of Japanese cars, but consumers are easily forgetful.

Reporter: For a company, what is the fundamental guarantee for sustainable development?

Cui Dongshu: The most fundamental issue is the establishment of a car brand reputation, to attract consumers with product loyalty and trust, the product is not necessarily technically advanced, but it can give consumers a sense of security, this feeling is behind the consumer Recognition of product quality.

Chen Wenkai: The continuous development of car companies still depends on technology and products themselves, followed by marketing promotion.

Reporter: How do you view the development prospects of Japanese car companies in the Chinese market?

Cui Dongshu: The prospect of Japanese cars in the Chinese market will not be declining all the way. Japanese cars will have opportunities for improvement. Japanese cars have been proven to have strong vitality in the global market. The performance of Japanese cars in the U.S. market proves that Japanese people are not particularly rigid in mind. They only suffer from product strategies in the Chinese market. If Japanese companies treat the Chinese market with the same attitude as the U.S. market, Japanese car companies must have a market in China. Good prospects for development.

Wenkai Chen: Japanese car companies were originally leading in China, and their market share has already fallen, but this is not a result. If Toyota and other car companies attach importance to the Chinese market, change the fundamental market strategy, and can quickly respond to changes in the Chinese market, timely close to the market, the Japanese car companies in the Chinese market, the prospects are more bright.

Forged Fittings

Forging is a workpiece or blank obtained by forging and deforming metal billets. The mechanical properties of the metal billet can be changed by applying pressure to the metal billet. According to the temperature of the billet during processing, the forging can be divided into cold forging warm forging and hot forging. Cold forging is usually done at room temperature, and hot forging is done at a recrystallization temperature higher than that of a metal blank.

The loose of metal can be eliminated by forging. Holes are made to improve the mechanical properties of the forgings.

Usage:

1, general industrial forgings refer to the civil industry, such as machine tool manufacturing, agricultural machinery, farm implements manufacturing and bearing industry.
2, forgings for hydrogenerators, such as main shaft and intermediate shaft.
3, forgings for thermal power stations, such as rotors, impellers, retaining rings, etc.
4, metallurgical machinery, such as cold roll, hot roll and herringbone gear shaft.
5, forgings for pressure vessels, such as cylinders, ring flanges and heads.
6, marine forgings, such as crankshaft, tail shaft, rudder rod, thrust shaft and intermediate shaft.
7, forging and pressing machinery and equipment, such as hammer head, hammer bar, hydraulic press column, cylinder body, wheel shaft press mounting machine's prop and cylinder body, etc.
8, modular forging is mainly used for forging dies for hot forging hammer.
9, automotive industry forgings, such as left, right steering knuckle, front beam, coupler, etc., according to statistics, in automobile, forging parts account for 80% of its quality.
10, forgings for locomotives, such as axles, wheels, leaf springs, crankshafts of locomotives, etc., according to statistics, the forging parts in locomotives account for 60% of their quality.
11, forgings for military industry, such as gun barrel, door body, breech bracket and traction ring, etc., according to statistics, forging parts account for 65% of the quality of tanks.
Characteristic:

1, the weight range is large. The forgings are small to several grams to hundreds of tons.
2, the quality of the casting is higher than that of the casting. The mechanical properties of the forgings are better than those of the castings, which can bear large impact forces and other heavy loads. Therefore, any important and large force parts are used forgings. For high carbides steel, forging is better than rolled steel. For example, high speed steel rolling material (or forging material) can be used only after forging. In particular, the high speed steel milling cutter must be changed.
3, the weight is the lightest. Under the premise of ensuring the strength of the design, the weight of the forgings is lighter than the weight of the castings. This reduces the weight of the machine itself. It is of great significance for the vehicles, aircraft, vehicles and characters.
4, save the raw materials. For example, the crankshaft of the static heavy 17kg used in the car is 189% of the weight of the crankshaft when the rolling material is forged. While the die forging is used, the chip is only 30%, and the machining time is also shortened by 1/6.
Precision forging can not only save more raw materials, but also save more machining hours.
5, high productivity. For example, the use of two hot die forging press forging radial thrust bearings, can replace 30 automatic cutting machine tools. When the M24 nut is produced by the top forging automaton, the productivity of the six axis automatic lathe is 17.5 times.
6, free forging is very flexible. Therefore, forging technology is widely used in some factories to produce various accessories.
