On July 12, 2017, the Ministry of Industry and Information Technology, the Ministry of Development and Reform, and the Ministry of Science and Technology jointly organized the acceptance meeting of the pilot project of methanol in Shaanxi Province, and piloted the methanol vehicles in three cities of Baoji, Xi'an and Yulin in Shaanxi Province. Acceptance. Relevant comrades from the Ministry of Transport, the Health and Family Planning Commission, and other departments of the Ministry of Industry and Information Technology, the Ministry of Industry and Information Technology, the pilot group of the Ministry of Industry and Information Technology, the relevant department comrades, Shaanxi Province, Shanxi Province, Shanghai, Guizhou Province, Gansu Province and other pilot provinces and cities Responsible comrades of the competent departments of industry and informatization, as well as responsible comrades of relevant departments of Baoji City, Xi'an City, Yulin Municipal People's Government and relevant units of pilot operations attended the meeting. Li Li, inspector of the Department of Energy Conservation and Comprehensive Utilization of the Ministry of Industry and Information Technology, attended the meeting and delivered a speech.
Sheet Metal Fabrication
Definition of sheet metal fabrication
Sheet Metal fabrication is the creation of useful metallic parts and structures by the application of multiple fabrication processes. Sheet metal fabrication is basically a broad term that involves various complex processes like cutting, forming, bending, welding, machining, and assembling. The instructions include below: materials, processes, and tools required for sheet metal fabrication.
Types of Sheet Metal Fabrication Materials
The choice of metal depends on the final use of the fabricated parts.
Common fabrication processes:
· Carbon Steel
· Stainless Steel
· Aluminum
· Bronze
· Copper
· Brass
· Aluminized steel
· Galvanized steel
Types of Metal Fabrication Processes
The journey to the final product from raw sheet metals proceeds through various sheet metal fabrication processes. All the sheet metal fabrication processes can be grouped into the following three categories:
· Cutting
· Deformation
· Assembly
Sheet metal fabrication: Cutting
ii. Water jet cutting
iii. Plasma cutting
Sheet metal fabrication: Forming or Deformation
Bending: Sheet metal bending is one of the most popular deformation processes. A machine known as a Press brake is used to bend sheet metals into V, U, or other complex shapes. With an increase in gauge thicknesses of sheet metals the force required to bend increases.
Stamping: In the stamping process, a hydraulic or mechanical stamping press equipped with a tool and die is used to perform specific tasks like curling, drawing, embossing, flanging, etc
Hemming: Hemming is a process by which the edges of sheet metal are folded over itself or another piece of sheet metal to create a rounded edge. In the sheet metal fabrication process, two types of hemming processes are widely involved. They are roll hemming and conventional die hemming. Conventional hemming is used for mass production. A hemming roller is used for roll hemming.
Spinning: Spinning is a metal fabrication process where a lathe machine is used to rotate the sheet metal against a tool to produce conical or cylindrical shapes.
Sheet metal fabrication: Assembly
Assembly is basically joining sheet metal components produced using above mentioned cutting or bending processes. The common sheet metal assembly process consists of joining by Welding and joining using fasteners.
Welding: In the welding process, sheet metal components are joined together by melting sections with the application of heat to form a solid connection. There are various processes available that are used to weld sheet metals.
Joining using Fasteners: Similar or dissimilar sheet metal parts can easily be joined using fasteners like bolts, screws, rivets, etc.
Brazing: Brazing is a process similar to welding that operates by melting a filler without melting the sheet metals.
Adhesives: Adhesives can be used to hold metal sheets together in conjunction with other joining methods
Advantages and Disadvantages of Sheet Metal Fabrication
As sheet metal fabrication covers a wide area of techniques and methods, the advantages and limitations will vary depending on the process used during fabrication.
Benefits:
i. Sheet metal fabrication is fast and can produce high-quality components.
i. A large number of processes are available with wide range of materials
ii. High strength to weight ratio for sheet metal fabricated parts.
Disadvantage:
i. Each fabrication process has their own limitations.
ii. High initial cost for set up of equipment and tools.
iii. Requirement of skilled labors for each process.

He Guangyuan, head of the methanol vehicle pilot expert group and former minister of the Ministry of Machinery Industry, served as the leader of the acceptance expert group. Professor Yao Chunde, deputy director of the State Key Laboratory of Internal Combustion Engines of Tianjin University, served as the deputy leader, including energy, automobile, environment, human health, Experts in occupational health, petroleum and petrochemical fields. The expert group conducted on-site verification of the pilot units of methanol vehicles in Baoji City, Xi'an City and Yulin City, and the methanol fuel supply units. The relevant materials and test reports were consulted and the relevant departments of Shaanxi Province, Baoji City, Xi'an City and Yulin City were heard. And the pilot work report of the relevant units, and questioned related issues. The expert group unanimously agreed that the three pilot cities should strengthen overall coordination and coordination according to the pilot implementation plan, carefully organize and implement, conscientiously do a good job in data collection and analysis and related testing, complete the objectives and tasks of the pilot, and recommend acceptance.
In the speech of the meeting, Li Li summarized the progress of the methanol vehicle pilot work, affirmed the pilot work of the pilot cities in Shaanxi Province, and put forward requirements for further advancement of the pilot work.
