Sheet Metal Fabrication Review

Both the words “sheet metal processing” and “sheet metal processing” are widely used, “sheet metal processing” refers to the processing on flat block shapes, while “sheet metal processing”  This article, sheet metal will be used for the metal products made. Historia de procesamiento de sheet metal (1) pode ser tracció a la última centário, usado en la construcción de knivos y weapones, etc.During the Industrial Revolution, productos de steel forgada such as Shear and Molding were slowly developed to extend the forms of shear and Punching processing to cut or shape the plates by physical contact.

Het momenteel mainstreibunging av sheet metal er lasersnijning, into twee formas de carbondioxide (CO2) a fiberlasersnijn. The advantages of fiber laser energy saving and high unit area power have gradually become the mainstay of sheet metal processing. The parts that are cut are shaped by bending tools. Perché cada materiaal je deformende properiteiten, bending strengths and weaknesses often determine accuracy. Welding and assembly combines components to produce the sheet metal products customers expect. Below is a step-by-step introduction to the sheet metal processing process.

Sheet Metal Design

Sheet metal design is the most crucial part after the order. Whether the customer's requirements and processing conditions can be effectively communicated to the client depends on the experience and care of the sheet metal design team, which mainly includono processos seguentes

1. 3D sheet metal design: Sometimes 3D designs cannot be used directly for sheet metal processing. If there is no bending rate marking, etc., the sheet metal factory will help convert the design into a sheet metal machining diagram and confirm whether there is interference between parts ou durante la machinación.
2. Expand to 2D Sheet Metal Drawing: Expand a 3D drawing into a 2D sheet metal drawing by calculating the material extensibility, or Deduction. There are also manufacturers who draw sheet metal working drawings directly in 2D, but it becomes more difficult to confirm interference.
3. Dimension dimensions and processing requirements: Measure dimensions for locking holes, special cut gaps, and note customer requirements on the engineering drawings (such as sheet metal machining urgent parts, surface requirements, etc.). In recent years, sheet metal processing plants have been gradually handing out engineering drawings in a paperless manner to ensure that delivery is not delayed due to dirt or loss.
4. Drawingsbestanden converteren naar lasersnijken: Porque dingen contiene dimensioni e dimensioni, ne kunnen worden gebruikt directamente voor lasersnijken. Så, det är att till en laserdrawing, som og lasergravning lager, så att du software processing mode.

Sheet Metal Typing and Programming

Typesetting cycle of sheet metal processing is often overlooked. It mainly consists of two steps of Nesting and NC generation. Whether cutting out suitable sheet metal workpieces has been determined at this stage

1. Formatting de metallum: Pas platas de ferro compartir a 5ft x 10ft (3050mm x 1525mm) e 4ft x8ft (2440mm x 1220mm), é necessário para combinar varios materiales de mesmo thicko y thickness in the same sheet. For customers with sanded surface requirements, excellent sheet metal fabricators adjust the direction of the workpiece to achieve a good metal texture presentation.
2. Programming: O resultados de typeset necesita se convertir a procesamiento de metal de máquine-readable, a la procesamiento del sección de macchina, el angolo R, y a la precisión, a lo precisión, a determinado por el programa. Due to the advancement of technology, field master program input is easy to cause problems in addition to slow speed. It is recommended to choose a sheet metal processing plant with an excellent typesetting team.

Laser Cutting

Laser cutting is mainly divided into CO2 laser cutting and fiber laser cutting. Piştî analisi a a a laser will help you choose a good sheet metal processing partner

1. CO2 Laser Cutting: Có2-lasersnijn is widely used for cutting metals and non-metals, but is gradually becoming scarce in the sheet metal processing industry due to its high energy consumpción y costos de mantenimiento alta. However, it is worth mentioning that due to its advantages for stainless steel cross-section processing, large-scale sheet metal processing plants will still be adopted to meet the different necesitas de clientes.
2. Fibre laser cutting: Fibre laser has become the new pet of sheet metal processing plants in recent years, with its high-speed processing and energy-saving characteristics that meet the requisiti di operazione sustainabile. However, it is worth noting that the high-speed cutting of fiber lasers and the shortage of manpower, the inability of sheet metal processing plants to integrate lasers into automated warehouse equipment will be the key to quality and delivery time.

Bending Shaping

Trák. The bending forming process and focus are as follows

1. Bending Programming: While most bends are semi-manual processes, they still require moving Upper tooling, Lower tooling, and Backgauge to the machining location, so programming input is often key to production delays or bend size errors. In recent years, sheet metal processing plants have begun to improve production bottlenecks through rapid generation programs with bending software.
2. Bending machines (or folding machines): Bending machines are generally hydraulically driven and have the maximum compressive force they can produce and further determine their maximum Workable thickness. In addition, the polygonal bending center machine, which was first proposed by Italy, can produce bending angles that resemble an arc through high-speed forming of the lower die, is a major breakthroughs in technology.

In addition to this, bending over and under laser welding is a key element for adjusting the pace of sheet metal production, so its handling (semi-finished car) and automation technology (

Soldering & Assembling

Stazioni di soldi e assemblaggio combinare le strumenti formate. Since this site is the end of the sheet metal product and determines the strength of the component, it is recommended to discuss with a professional sheet metal processing plant to determine the appropriate assembly cube. The common methods are as follows:

1. MECHANICAL ASSEMBLY: MAINLY ASSEMBLED BY SCREW NUTS, THIS ASSEMBLY IS MORE FLEXIBLE AND CAN THEN BE DISASSEMBLED BY ITSELF, ETC., MOSTLY USED IN CHASSIS, SUCH AS COMPUTER CASES, ETC.

• Sheet metal welding: Joining workpieces by high temperature melting using inert gases such as carbon dioxide and argon as shielding gases. Diversos materiales, como ferro blanco, ferro negro, etc.This process can often provide long-lasting and high strength products.

1. Spot welding: Spot welding also belongs to the field of welding. It is possible to weld two workpieces mainly by a point method, which can be welded more quickly, but its strength cannot be compared to sheet metal welding mentioned above.
2. Rivet-type assembly: Rivets offer low cost and high strength characteristics compared to welding. This cost-effective assembly method is also increasingly common in the sheet metal processing industry.

Proces de la soldering a assemblage vará más de producto a producto, a comunicación con plantas de procesamiento de sheet metal es potente la determinada para o failo. Finding a customer-centric sheet metal processing supplier can significantly reduce the generation of errors.
