What does "sheet metal" mean?

Question 1: What does automotive sheet metal mean? Sheet metal is a kind of work of automobile repair, mainly aimed at the appearance of the car body. The replacement, repair, rectification and painting of external bodies (such as bumpers and doors) also belong to the category of sheet metal work. Sheet metal has a specific division of labor, which covers all the above contents in a broad sense, while sheet metal in a narrow sense only replaces the external body, and generally repairs the shape of the car by welding and shelving.

Question 2: What is sheet metal? Up to now, there is no complete definition of sheet metal. According to a definition in foreign professional journals, it can be defined as: sheet metal is a comprehensive cold working process for metal plates (usually less than 6mm), including cutting, punching/cutting/compounding, folding, welding, riveting, splicing and forming (such as automobile body). Its remarkable feature is that the thickness of the same part is consistent.

Question 3: What is a sheet metal part? Sheet metal parts are products processed by sheet metal technology, and we can't live without sheet metal parts everywhere. Sheet metal parts are made by filament winding, laser cutting, heavy machining, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending forming, die forging, water jet cutting and precision welding.

Generally speaking, the basic equipment of a sheet metal factory includes shearing machine, CNC punch, laser, plasma, laser (PLA * * * a)/ Ning Bin machine, bending machine, uncoiler, straightener, deburring machine and other auxiliary equipment.

Generally, the three most important steps in a sheet metal factory are cutting, stamping/cutting and folding.

Metal sheet is sometimes called metal sheet, which comes from English platemetal. In general, some metal plates are plastically deformed by manual or die stamping to form the required shape and size, and further more complex parts can be formed by welding or a small amount of mechanical processing, such as chimneys, tin furnaces and automobile shells commonly used in families.

Sheet metal processing is called sheet metal processing. Specifically, such as making chimneys, iron drums, oil tanks, oil pots, ventilation pipes, elbows, gardens, funnels, etc. For plates, the main processes are cutting, bending, forming, welding, riveting and so on. This requires a certain knowledge of geometry.

Sheet metal parts are sheet metal parts, that is, parts that can be processed by stamping, bending and drawing. The general definition is-

Parts with constant thickness during machining correspond to castings, forgings and machined parts. For example, the iron shell outside the car is sheet metal, and some cabinets made of stainless steel are also sheet metal.

Modern sheet metal processes include filament winding, laser cutting, rework, metal bonding, metal stretching, plasma cutting, precision welding, roll forming, sheet metal bending forming, die forging, water jet cutting, precision welding and so on.

In the current 3D software, SolidWorks, UG, Pro/E, SolidEdge, TopSolid and so on. There is a sheet metal part, and the data needed for sheet metal processing (such as unfolded drawing, bending line, etc.) are obtained mainly by editing 3D graphics. ) and used for CNC punch/laser, plasma and water jet cutting machine (laser, PLA * * * A, water jet cutting machine)/Ningbin machine and CNC bending machine, etc.

Question 4: What is a sheet metal worker? What's the main reason? Occupation name: cold working sheet metal worker

Occupation definition: a person who carries out cold and hot forming and riveting on metal plates. chicken (as food)

Occupation grade: This occupation is divided into five grades.

Primary (national vocational qualification level 5)

Intermediate (national vocational qualification level 4)

Advanced (National Vocational Qualification Level 3)

Technician (National Vocational Qualification Level II)

Senior technician (national vocational qualification level 1)

Question 5: What is body panel paint? Body panel painting is to process and coat metal plates such as steel plates, aluminum plates and copper plates. Baking paint is to brush the base material with primer for three times and topcoat for four times, and each brush is sent to a dust-free constant temperature curing barn for baking.

Up to now, there is no complete definition of sheet metal. According to a definition in foreign professional journals, it can be defined as: Sheet metal storage is a comprehensive cold working process for sheet metal (usually less than 6mm), including shearing, punching/cutting/compounding, folding, riveting, splicing and forming (such as automobile body). Its remarkable feature is that the thickness of the same part is consistent.

Question 6: What does automotive sheet metal include? ? Automotive sheet metal includes seven categories: first, the repair of concave-convex damage of car body; The second is the repair of car body rust and mildew; Third, the replacement of automobile windshield; Fourth, the repair of plastic parts of the car body; Five, human skeleton distortion, wrinkle correction; 6. Replacement of integral structural parts in body maintenance; Seven, the overall deformation of the car body repair.

Question 7: What does automotive sheet metal mainly do in sheet metal? Actually, very learned. Many basic car modifications are classified as sheet metal, such as chimneys, dustpans, air conditioning pipe flange frames, etc. Automotive sheet metal is mainly engaged in disassembly (not involving engines). Basically, it is the living surface repair of sheet metal and beam correction welding (oxygen shielded welding of electric welding machine). The instruments used in gas argon arc welding include sheet metal repair machine, oxygen shielded welding machine, beam corrector, factory, etc. Factory equipment with better conditions is also willing to work all the time. Some secondary garages are in poor condition, and no equipment takes twice as long to complete. In the field of automobile repair, sheet metal is the most. First of all, you should flatten it when you repair it, otherwise the painter will not be willing to scrape putty. Machine repairs with poor beam alignment will be found back and the engine will be installed. Master Zhen leads the door to practice, and you are a master if you are diligent and flexible. Now I'm in Beijing, and the Master of Sheet Metal in Class Two gets about 4,000. The benefit of 4S shop is good, and everyone in the garage takes commission and does much more. Believe in yourself, I am also a sheet metal worker. Going to work every day is a pleasure. I wish you success!

Question 8: What is body painting? Please be specific ... car body panel painting means that when a car has a traffic accident, the car is sent to the garage for car body panel painting after two cars collide. Sheet metal means to repair the collision place to the original factory. Repair the crashed car with oxygen, electric welding, connecting poles and hanging keys. Painting is the color of the car before. Now the car is painted in that color, and it can be changed into other colors. The painting process includes putty, water sandpaper and gray primer, and then it can be sprayed into the dust-free curing barn. After painting, it must be dried in the dust-free curing barn before leaving it.

Question 9: What does the sheet metal tool body do? Sheet metal workers mainly use the plasticity of materials to form various fixed parts (including blanking and shape correction) through cold pressing. Grasping the "receiving" and "releasing" of sheet metal is the basis of sheet metal making. Sheet metal is easy first, then difficult, easy to use and not easy to level again. At present, making money from sheet metal is still considerable.
