Sheet metal workshop laser cutting processing using CO2 laser or YAC laser, two-dimensional and three-dimensional cutting processing, with high cutting accuracy. Laser source power varies from 5W to 90kW have a series of products, sheet metal laser cutting processing is mainly the use of 100W ~ 1500W power laser. When the output power of the laser source is less than 1500W, the laser source is in single-mode oscillation mode, and the width of 0.2mm can be cut, which is clean and flat after cutting with power; When the output power of the laser source is greater than 1500w, the laser source is in multi-mode oscillation mode and can be cut with a width of 1mm, but there will be a small amount of dirt after the power cutting.

Auxiliary gases, including air, oxygen and nitrogen, should be used when cutting thick plates. Nitrogen can prevent the oxidation of the section during the cutting process, and oxygen is suitable for high-speed cutting of thick plates. Sheet metal workshop laser cutting can use CAD or CAM technology to provide processing information and processing parameters for processing workpiece models and lasers, which can quickly and accurately complete production and realize automatic cutting. Laser cutting especially needs to replace the mold, which can shorten the production preparation cycle and reduce the production cost.

Sheet metal workshop laser cutting processing technology as a new process, is the product of modern scientific development, laser cutting processing technology, laser welding technology, laser punching technology and laser forming technology in sheet metal car rush production and processing also need skilled technicians. With the development of laser material processing technology, sheet metal workshop production and processing will inevitably achieve a degree of stability, reliability, efficiency and high automation.

Compressed air assisted cutting also achieves the same edge quality as cutting components with oxygen or nitrogen. The cut edges need to be clean enough so that most of the powder coating can be attached without the need for a second cleaning. The size of the resonator was a significant limitation when the first choice was made to use compressed air for auxiliary laser cutting. Now, however, high-wattle laser cutters - typically more than 4,000 W - make air-assisted cutting an effective method for steel, stainless steel and aluminum up to 1/8 inch thick (about 3mm). Laser cutters with a 6000W resonator can even cut materials up to 3/8 inch thick (about 9.5mm).

This startling discovery changed the way products and components were manufactured at Doyle in Palmyra, Missouri, 50 years ago, and the processing time was reduced by more than 90 percent from a CL-940 fiber laser cutting machine from CincinnatiInc., At the same time, the use of nitrogen is only a fraction of the original cost of air-assisted gas cutting fiber laser systems. "The new fiber laser cutting machine is a game changer and changes the way we think about product manufacturing." Said the head of Doyle Company.

Indeed, laser technology continues to surprise us and revolutionize manufacturing methods that have been shackled by the industry for years.

The HCF3015I series fiber laser cutting machine launched by Huineng Optoelectronics in recent years, which is rapidly popular in the industry, provides fiber transmission and flexible processing to meet a variety of processing needs. The maximum cutting speed of 1mm stainless steel sheet is 22m/min, and the maximum cutting speed of 0.5mm stainless steel sheet can reach 40m/nin. HCF3015I series is equipped with double switching table, cutting and loading are carried out at the same time, the table is equipped with ball to facilitate the plate movement; Coarse positioning device with clamp can position the plate, while preventing movement, high processing accuracy and less waste.

When it comes to laser cutting, it is natural that the well-known laser giant in China - large family laser. In a recent message said that the next step of Dazu laser plans to carry out new technological innovation layout in the fields of light source manufacturing, high-power cutting and welding, industrial robots, robot basic original device research and development, which shows its ambitious ambitions. In the field of sheet metal cutting, Dazu G3015F fiber laser cutting machine is also famous, is the first Dazu laser in China, to reach the international leading level of a mature product, successfully won a number of industry awards. The G3015F uses optical fiber transmission and flexible processing to achieve high-quality cutting of any shape, and is suitable for cutting high inverse materials such as copper and aluminum. This series of products has a strong cutting ability, "flying" cutting speed, very low operating costs, excellent stability, high quality processing and strong adaptability and other incomparable advantages. Among them, the cutting speed of 1mm stainless steel is 40m/min, and the cutting speed of 0.5mm stainless steel is up to 100m/min.

Behind the laser cutting machine that can make the processing "fly" up, the importance of the invisible hero - the laser is self-evident. The TRUMPF TruFlow series CO2 laser with a maximum power of 10000W can be used for laser cutting, laser welding and surface processing. With a folded square structure and a constant temperature for all parts of the gas laser vibrator under thermal load, the TruFlow series of lasers offers excellent thermodynamic and mechanical stability. After decades of development history, this series of lasers enables users to obtain reproducible, high-quality machining results.

Non-standard equipment manufacturing process requires a large number of non-standard sheet metal parts processing, with the continuous progress of China's economy and science and technology, and CNC machine tools have strong adaptability to the workpiece modification, high processing accuracy, high productivity characteristics; Therefore, numerical control technology has been widely used in sheet metal machine tools, which solves the problems of high precision parts, complex shape, irregular, large batch and so on in sheet metal processing, and the simple operation of numerical control system greatly reduces the labor intensity of workers.

Non-standard equipment manufacturing process requires a large number of non-standard sheet metal parts processing, sheet metal parts shape is not fixed, traditional processing methods are difficult, high energy consumption. The introduction of numerical control technology has been widely used in sheet metal machine tools, it solves the problems of high accuracy, complex shape, large batch and other problems in sheet metal processing, and has strong adaptability to the workpiece modification, high processing accuracy, improve productivity and other characteristics, and sheet metal processing technology is developing in the direction of diversification.

At present, sheet metal can be defined as: a comprehensive cold working process for sheet metal (usually less than 6mm), including cutting, punching/cutting/compounding, bending, welding, riveting, splicing, forming (such as car bodies). Its remarkable feature is the same thickness of the same part. Generally speaking, the basic equipment of sheet metal includes shearing machine, CNC punching machine/laser, plasma, water jet cutting machine, flame cutting machine, bending machine, and various auxiliary equipment such as: uncoiling machine, leveling machine, deburring machine, spot welding machine, biting machine, etc. Sheet metal is sometimes also known as metal plate, the word comes from the English platemetal, is generally some metal sheet through manual or mold stamping to produce plastic deformation, form the desired shape and size, and can be further through welding or a small amount of mechanical processing to form more complex parts, such as the chimney, iron furnace commonly used in the family. And the shell of the car is all sheet metal.

Generally, the three most important steps in sheet metal are cutting, punching/cutting, and bending.

Through the use of CNC equipment in recent years, can enhance the processing capacity of non-standard sheet metal parts, such as the main CNC water jet cutting machine, CNC shearing machine, CNC bending machine, CNC turret punch, spot welding machine, plasma cutting machine and other equipment can form a complete set of sheet metal processing production line. At present, the domestic use of more cutting plate, bending CNC system such as the Dutch DELEM system, the control system application is more mature and stable.

Sheet cutting is the first process in sheet metal processing, and the accuracy of cutting directly affects the processing quality of the following process. CNC shearing machine is composed of CNC device, servo system, measuring device and machine tool. The servo system is composed of three servo motors and a servo drive device. There are two servo motors positioned in front of the machine tool, usually a main motor works separately, such as processing the hypotenuse, the auxiliary motor works, and the CNC system gives two different instructions to form the hypotenuse. There is a servo motor in the rear position. The application of numerical control shearing machine makes the mass of repeated cutting to avoid the scribing, line-matching process, improve labor efficiency, and ensure the size of the cutting and the tolerance of the cutting diagonal.

CNC water jet cutting machine completes the processing of complex shapes and perforated sheet metal parts, and the machine operator determines the processing plan according to the part drawing and process requirements. The operator writes the program directly into the program memory through the operation panel of the machine tool; With the increasing maturity of microelectronics and computer technology, the development of numerical control technology in China has been promoted. With the development of CAD/CAM technology, the operator can input the graphics into the computer through computer-related software to generate the program, copy the disk through the disk drive to enter the numerical control system. Can also use the computer and numerical control system serial input method. The application of CNC water jet cutting machine makes the original complex shape structure processing simple, the processing of porous parts a positioning cutting molding, cutting accuracy up to ±0.1mm.

What does the word "sheet metal" remind you of? Most people would probably answer something like "baking pan" or "baffle." That's because they don't know what Herbert Staufer, head of high power welding at Volners International, is doing at TrumPF Australia's production plant in Pasching. The steel plates are four meters long, 200 millimeters thick and ankle high on the ground. Volnerz became one of the leading suppliers of composite welders, and it is no surprise that Staufer knows this material like the back of his hand.

He usually travels to Pasching as a client, but has recently become a supplier on joint projects. Thomas Reiter, Staufer's project partner and customer for sheet metal processing in Pasching, explained the reason for inviting Staufer to participate in the project: "We have to weld these sheets and make them into the frame of the bending machine, which requires very specialized welding techniques." To show what was actually going on, the two men lowered their metal plates and walked toward a gray wall that looked like the outside of a windowless production plant, but was clearly inside the workshop. The TruDisk 8002 disc laser leans against the wall and is quite small by comparison.

On the other side of the wall, a hydraulic system in a large laser safe room lifts 20 tons of steel plates and tilts them to the desired Angle. The beam moves over the device, extends a robotic arm equipped with a composite welding head, slowly moves across the first row of weld joints, uses a laser to heat the material, and then begins the heavy work: the laser beam and metal active gas (MAG) arc torch work together to weld the weld. These solder joints are up to 8 mm thick and can eventually withstand up to 320 tons of pressure. This constant repetition enables the press to work properly throughout its service life.

Outside the laser room, Staufer and Reiter watch the process on a monitor. Reiter says, "We once sent the frame outside for hand welding, which took a whole week! Since then, we are determined to improve efficiency." He soon found that laser composite welding was the right solution. "This welding process is much faster because we only need one weld, unlike arc welding which has to be done bit by bit. We can also use lasers to preheat the material, and automatic processing is easier to ensure quality." So he called this solution Plan A, and just in case, he prepared Plan B - an automated solution that can be paired with traditional MAG welding robots. "But Plan B requires preheating and subsequent stress-relieving heat treatment." So no one wants to use Plan B, Reiter says. But there is A huge problem with Option A, as Staufer says: "We have delivered more than a hundred laser composite welding heads, but the thickest sheet ever processed is only 10 mm."
