Definition of Sheet Metal - Sheet Metal Processing
Definition of Sheet Metal
Sheet metal has not yet had a relatively complete definition
According to a definition in a foreign professional journal, it can be defined as: Sheet metal is a comprehensive cold working process for metal sheets (usually below 6mm), including shearing, punching/cutting/compounding, folding, welding, riveting, splicing , forming (such as car body) and so on. Its remarkable feature is that the thickness of the same part is the same.
Sheet metal processing is called sheet metal processing. Specifically, for example, the use of plates to make chimneys, iron drums, fuel tanks and oil cans, ventilation pipes, elbows and heads, Tianyuan places, funnel shapes, etc., the main processes are cutting, bending, bending, bending, welding, riveting, etc. Some knowledge of geometry.
Sheet metal parts are thin-plate hardware parts, that is, parts that can be processed by means of stamping, bending, stretching, etc. A general definition is-
Parts with constant thickness during machining. Correspondingly, castings, forgings, machined parts, etc. For example, the outer iron shell of a car is a sheet metal part, and some stainless steel kitchen utensils are also sheet metal parts.
1. It is a processing method of automobile maintenance, also known as cold work.
To put it directly, if the appearance of the body is damaged and deformed, the process of sheet metal is required to restore the original appearance.
Basically the tool used is a hammer. Hammers of different shapes, put iron blocks behind the sheet parts, and beat them repeatedly to make them take shape.
Appearance restorers are also used when necessary. This thing actually belongs to welding. Weld the hoop to the body and pull it out with the hook. Used to repair sunken areas.
A large flat body is generally difficult to get back in place, so it is sometimes used to close the fire. It is to cool down after local heating, so that the iron sheet shrinks.
The ultimate goal is to restore the damaged body to its original appearance.
2. Sheet metal: Sheet, which means plate, thin plate, is the meaning of serial processing of thin metal plates, including folding, shearing, punching, welding, riveting, splicing and other processes
3. This is a design module, mainly for things made of iron materials. It is different from the entity, the thickness of the entity varies, but the sheet metal is basically the same thickness, and there are many products made of sheet metal in life.
According to data, about 70% of the total cost of automobiles is a part of automobile parts procurement. When the procurement cost decreases by 1%, profits increase by 5-10%, and when sales increase by 1%, profits only increase by 1%. It is obvious that reducing procurement costs can easily increase profits and enhance competitive advantages. So, let's take a look at the automotive parts procurement system and supplier management analysis together!
Sheet metal is a product processed by sheet metal technology, and we cannot live without sheet metal everywhere. Sheet metal parts are made through filament power winding, laser cutting, heavy processing, metal bonding, metal stretching, plasma cutting, precision welding, rolling forming, sheet metal bending forming, die forging, and water jet cutting.
Connecting buffer water tanks in series in the central air conditioning system can increase the water capacity of small systems, store cooling or heat, and effectively solve problems such as load fluctuations and frequent host startup caused by small systems, thus achieving the goal of extending equipment service life and saving energy.
Car charging cabinet sheet metal manufacturers: What are the precautions for customizing sheet metal processing cabinets?
Reasons and Solutions for Edge Burning of Popular Laser Cutting Machines Used by Automobile Charging Cabinet Sheet Metal Manufacturers Reasons and solutions for edge burning in laser cutting machines Today, the sheet metal manufacturer of car charging cabinets will share with you the reasons and solutions for the edge burning of popular laser cutting machines. I hope the following content can help everyone. Car charging cabinet sheet metal manufacturer: analysis of the reasons for edge burning of metal laser cutting machines The reason for edge burning and slag sticking in laser cutting of sheet metal parts: When laser cutting sheet metal parts, a large amount of heat is generated. Generally, the heat generated by cutting will diffuse along the slit into the processed metal plate, obtaining sufficient cooling. When metal laser cutting machines process small holes, the outside of the hole can be fully cooled, but the heat diffusion space inside a single hole is small, and the heat energy is too concentrated, leading to phenomena such as overburning and slag hanging. In addition, in thick plate cutting, the molten metal and heat accumulated on the material surface during perforation can cause auxiliary airflow disorder and excessive heat input, leading to overburning. Car charging cabinet sheet metal manufacturers: How to solve the problem of burning edges and slag hanging Solution to overburning in laser cutting of carbon steel holes: In carbon steel cutting with oxygen as the auxiliary gas, the key to solving the problem lies in how to prevent the generation of oxidation reaction heat. When piercing, auxiliary oxygen cutting is used, and after a delay, auxiliary air or nitrogen cutting is used. This method can process holes in 1/6 thick plates. Pulse cutting conditions with low frequency peak output power can reduce heat output and help optimize cutting conditions. Setting the conditions as a single pulse laser beam, high energy intensity, and low frequency peak output can effectively reduce the accumulation of molten metal on the material surface during the perforation process, effectively stopping heat output. Solution for laser cutting of aluminum alloy and stainless steel: In the processing of such materials, nitrogen gas is used as the auxiliary gas, and there will be no burning phenomenon during cutting. However, due to the high temperature of the material inside the small hole, the phenomenon of internal slag hanging will be more frequent. An effective solution is to increase the pressure of the auxiliary gas and set the conditions to high peak output and low-frequency pulse conditions. When using air as the auxiliary gas, just like when using nitrogen, there will be no overburning, but bottom slagging is easy to occur. Therefore, it is necessary to set the conditions to high auxiliary gas pressure, high peak output, and low-frequency pulse. The above is the reason and solution for laser cutting machine edge burning explained by the sheet metal manufacturer of the car charging cabinet. Do you all understand?
