Sheet metal processing technology includes traditional cutting blanking, blanking processing, bending and pressing forming, parts welding and so on, and includes a variety of cold stamping die structure and process parameters, a variety of equipment working principle and control methods, but also includes new stamping technology and new process.
Aria’s sheet metal products can be used for rapid prototyping of low volume production and mass production.
sheet metal fabrication processes
Sheet metal processing is the process of forming a sheet metal into the desired shape using different manufacturing methods, including cutting, bending, surface treatment, assembly and many other steps.
From sheet metal to metal products from the process of CAD drawing, drawing completed, through the sheet metal manufacturing process, made into a variety of parts. The most common processing methods are:
Thermal cutting
Laser cutting is the first choice for cutting sheets. It is a very fast and precise cutting method that ensures good results. For thicker materials, plasma cutting can also be used, but laser cutting is of better quality.
Mechanical cutting
Shear or die cutting is the process of cutting sheet metal without burning or melting it, essentially not so different from cutting clothes with scissors.
During the shearing process, the punch presses the workpiece against a fixed die or blade, and the gap between the two makes it impossible for the workpiece to pass through, thus completing the shearing.
Metal deformation
Sheet metal contouring into several shapes with hand or brake press, This can be the most difficult step in metal fabrication due to the complexity of some bending, and engineers must be very familiar with the bending properties of metals.
Stamping
Stamping is another method of cutting holes in the sheet, using metal punches to punch holes in the sheet, which is suitable for mass production but not cost-effective for small batch production. It is use of two dies to press and stamp the metal until the desired shape is achieved.
Spinning
Sheet metal rotation high speed turning machine to form an axially symmetrical part.
Metal forming / assembly
The use of rivets or welds to assemble and join sheet metal parts. Assembly is usually the last or penultimate step in the completion of a product. If assembly involves welding, it is necessary to ensure that the parts are clean. If parts have been powder sprayed, they are usually assembled using other methods such as riveting and bolting.
SCOPE OF APPLICATION
The most common and sought after process in metalworking is the manufacture of sheet metal parts. The production of such parts is relatively simple and low cost, while they are successfully used in a variety of areas:
- Cases for various devices
- Production Equipment Details
- Parts for machinery and industrial machines
Metal profile
Machine tools for sheet metal processing and parts manufacturing are constantly being improved, and every year their capabilities increase: there are more and more areas in which such products are useful.
ADVANTAGES OF Aria PRODUCTION METHOD
We produce parts on special CNC machines that are ideal for sheet metal work. Due to this, our production has a number of significant advantages over other methods of manufacturing parts:
- we can work with large volumes without losing quality;
- The possibility of defective products is minimized;
- Parts after machine tools do not need additional processing, which saves money and time for production;
- Machines allow you to create parts according to complex drawings.
METAL PROCESSING BEFORE BENDING
During processing, before sheet metal fabrication, the following types of procedures are performed:
- panoramic deformation – the material is deformed by the translational movement of the machine, pulling it with the upper traverse;
- stamping – pressing machines are involved in the process;
- Curling – the firmware advances the upper traverse, which performs the fold with a special type of panoramic stroke.
When fabrication metal, the machines are programmed to manufacture the part according to the available schemes. You can receive details of any complexity.
METAL BENDING TECHNOLOGY
The fabrication process takes place in several stages:
- elastic tension;
- neutral state;
- Plastic tension.
Smooth workpieces are usually cold worked, without heating. Using heat, parts with a thickness of 12-16 mm are developed, as well as monoplastic materials, high-carbon steels and titanium. For materials with limited plasticity and alloys, it is important to take into account the location of the fibers that are inside.
When the direction of the fiber of the material coincides with the direction of movement of the axis of the workpiece being bent, damage during manufacture is unlikely.
In order to prevent rejection of products, the following points are taken into account:
- the direction of the fibers in the sheet metal to be processed;
- possible discrepancies with the form of the given final result;
- material flow indicators;
- Possible level of deformation, depending on the thickness of the workpiece.
If all these points are taken into account, and with the correct calculation of all parameters, metal fabrication defects are reduced to a minimum.
TYPES OF SHEET METAL BENDING
There are two main types of sheet metal fabrication:
- Manual metal fabrication. This is a type of sheet metal fabrication using a hammer and a clamping vise. This method is usually used in home or limited production environments with small volumes of products created.
- Mechanical fabrication of metal. It is used in production conditions on high-tech equipment. For work, machines, rolling equipment and fabrication presses are used.
The first method requires great physical strength and is limited by human capabilities. The second method allows you to perform work of any complexity, as the most powerful machines are involved.
The fabrication of the material is carried out in a cold state, since special efforts are not required for shaping on the machines. The exception is alloys that require heat treatment. When heated, you can change the angle of any material.
CUSTOM METAL BENDING SERVICES
Sheet metal fabrication services are in high demand today. The technology is widely used because it eliminates the need for stamps. As a result, the products are seamless, absolutely solid and taking into account all the folds, parameters and angles. On an industrial scale, the absence of welds is a very important advantage, since this feature improves the quality and aesthetic properties of the product.
BENEFITS OF METAL BENDING
Benefits of sheet metal fabrication:
- fast way to manufacture products;
- lack of welds, which improves the quality and aesthetic appearance of the product;
- low susceptibility to corrosion;
- the metal retains its physical and chemical composition;
- the details exactly correspond to the drawings and do not differ from each other within the same batch;
- high strength and durability of products due to the absence of thermal effects on the material;
- long service life of products;
- automated control.
The cost of fabrication metal today is affordable, this is due to factors such as automated production, minimization of manual labor and high equipment intensity.
