Go dry! Will fuel cell vehicles accelerate in 2017?

New energy automotive industry, people have to understand about fuel cells, fuel cell vehicles even better than pure electric vehicles in the truck, endurance, energy, etc., hydrogen fuel is known as the ultimate goal of the new energy vehicles, but fuel The development speed of battery cars is far less than that of pure electric vehicles. However, in the past two months, the exposure rate of fuel cells has exceeded the level of the first half of last year, which makes the electric vehicle resource network writers somewhat surprised. The author has checked the information and found that many companies have recently set their sights on the fuel cell field and spent huge sums of money on the fuel cell business. Will this year be the year when fuel cell vehicles start to start?

Policy has spawned more "crabs" companies

It is understood that at present, there are only 200 hydrogen fuel cell vehicles used in demonstrations in China, which are basically buses. From the model products declared by enterprises, the number of commercial vehicles for fuel cells is greater than that of passenger cars, mainly Yutong Bus and Foton Motor. Young cars and other companies are trying to develop and produce fuel cell vehicle products. Therefore, fuel cells are still in the exploration stage. However, the policy has spawned more companies involved in the fuel cell field.

On December 29 last year, the “Notice on Adjusting the Financial Subsidy Policy for the Promotion and Application of New Energy Vehicles” issued by the four ministries and commissions clearly pointed out that the subsidies for fuel cell vehicles will not decline, and the fuel cell passenger vehicles will be 200,000 yuan per vehicle; light passenger vehicles and trucks. 300,000 yuan / vehicle; large and medium-sized passenger cars, medium and heavy-duty trucks 500,000 yuan / vehicle.

Most local fuel cell vehicle subsidies are maintained at a 1:1 quota with state subsidies. At the same time, technical research and development incentives and supporting facilities support may be given to encourage enterprises to innovate and develop.

In addition, documents such as "Made in China 2025", "Technology Roadmap for Energy Saving and New Energy Vehicles" and "National Strategic Emerging Industry Development Plan for the 13th Five-Year Plan" also specify energy-saving vehicles, new energy vehicles and intelligent networks. The development direction and path of the company's automotive technology, the fuel cell enterprise industrialization goals.

The favorable policy is not only a reassurance but also a stimulant. More and more companies dare to eat crabs. Ocean Electric, Camel, Luxiao Technology, Yufu, and Furui are all involved in the field of fuel cells. Win at the starting line.

The long road to industrialization of fuel cells

It is not cheap to build an electric car, and the fuel cell car is more expensive to manufacture. Therefore, subsidies for fuel cells are generally more excusable than other new energy vehicles. However, if you only pursue immediate and short-term benefits, it is obviously insufficient. In order to let companies take such a big risk, because the cost of product development and security risks are high, and the infrastructure is also blank, companies should be very clear about what they are facing.

According to the current planning of some enterprises, it is obviously also a step by step, but also combined with China's national conditions. 1. At present, the gap between China's fuel cell core technology and Europe, America, Japan and South Korea is significant. Therefore, in the research and development of core technologies, domestic companies choose to cooperate with powerful international companies, such as Ocean Electric and Ballard, and Furuit. Packed up with the famous fuel cell company of PlugPower INC; 2. Take commercial vehicles as the entry point and gradually realize the commercial use of fuel cell vehicles; 3. Sign the long-term agreement, the product development and promotion have medium and long-term planning, corporate goals Implementation is a step-by-step process. For example, the "Fuel Cell Module Assembly Framework Agreement" signed by Ocean Electric and Ballard, the agreement time is 5 years, Furit installed to promote 500 fuel cell logistics vehicles in 2017, and promote 3000 vehicles in 2018, so this year is only the enterprise The first step in the field of fuel cells.

Several major limiting factors for the development of fuel cell vehicles are simply summarized as follows: the technical level is vastly different from that of Europe, the United States, Japan and South Korea, the infrastructure is imperfect, the technical standards are not perfect, and the social awareness is not high. These problems are not only objective facts, but also long-standing, and the country's goal is to achieve fuel cell vehicle industrialization by 2020. It is only three or four years since the arrival of 2020. Pure electric vehicles have developed over the years. There are still many problems to be solved, so the fuel cell vehicle industry wants to use this short period of three or four years to achieve a small chance of overtaking in the corner. In addition to the investment of enterprises, the government also needs more support.

CNC Milling

CNC Milling is to use the rotating multitool to cut workpieces, such processing method is efficient. Tool rotate (background) while working, and the workpieces move (as a feed movement), workpieces can also be fixed, but at the moment, rotate tool must also move (at the same time to complete the main motion and feed motion).Milling machine has a horizontal milling machine or vertical milling machine, large gantry milling machine.The machine tool can be ordinary machine tool, can also be a nc machine tools. With rotating cutter as a cutting tool.Milling is generally conducted on milling and boring machine, suitable for processing plane, groove, all kinds of forming surface (such as spline gear and thread) and special shape mould surface, etc
The characteristic of the CNC Milling is:
(1) cutter blade periodically participate in continuous cutting.
(2) each blade in the process of cutting, cutting thickness is variable.
(3) each tooth feeding alpha f (mm/teeth), said cutter every turn a blade workpieces relative displacement of time.
