Sheet Metal Fabrication is called sheet metal. Specifically, for example, the use of plates to make chimneys, iron barrels, fuel tanks, oil tanks, ventilation pipes, elbows and small heads, sky-round areas, funnels, etc. The main process include cutting(laser cutting), bending, bending, forming, welding, riveting, etc. Certain geometric knowledge. Sheet metal parts are thin metal parts, that is, parts that can be processed by stamping, bending, stretching and other means. With the development of laser drilling technology, the laser cutter has realized automated operation. The application in the sheet metal industry has changed the fabrication method of traditional sheet metal technology, realized unmanned operation, greatly improved production efficiency, and realized the whole process. The automatic operation has promoted the development of the sheet metal economy, and has improved the punching effect to higher level, and the effect is remarkable.

The Influence Of Materials On Sheet Metal Fabrication Technology


Sheet metal fabrication is a key technology that sheet metal technicians need to master, and it is also an important process for forming sheet metal products. Sheet metal fabrication includes traditional cutting, blanking, bending and forming and other methods and process parameters, as well as various cold stamping die structures and process parameters, various equipment working principles and operating methods, and new stamping technology. and new technology. The fabrication of sheet metal parts is called sheet metal fabrication. 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 a part with a constant thickness during fabrication.There are three main types of sheet metal fabrication: punching, bending and stretching. Different fabrication techniques have different requirements for the sheet metal. The selection of sheet metal materials should also consider the selection of sheet metal according to the approximate shape and fabrication technology of the product.

The Material Influence Of Blanking


Blanking requires that the sheet should have sufficient plasticity to ensure that the sheet does not crack during blanking. Soft materials (such as pure aluminum, rust-proof aluminum, brass, red copper, low carbon steel, etc.) have good punching properties, and parts with smooth cross-section and small inclination can be obtained after punching; hard materials (such as high carbon Steel, stainless steel, duralumin, super duralumin, etc.) have poor quality after blanking, and the unevenness of the section is large, especially for thick sheets. For brittle materials, tearing is easy to occur after punching, especially when the width is small.

The Material Influence Of CNC Bending Process


Sheets that need to be bent should have sufficient plasticity and a lower yield limit. The sheet with high plasticity is not easy to crack when bending, and the sheet with lower yield limit and lower elastic modulus has small rebound deformation after bending, and it is easy to obtain the bending shape with accurate size. Materials with good plasticity such as low carbon steel, brass and aluminum with carbon content less than 0.2% are easy to bend and form; materials with greater brittleness, such as phosphor bronze (QSn6.5~2.5), spring steel (65Mn), hard aluminum , super hard aluminum, etc., must have a relatively large relative bending radius (r/t) when bending, otherwise cracking is easy to occur during the bending process.

Special attention should be paid to the selection of the hard and soft state of the material, which has a great influence on the bending performance. For many brittle materials, bending will cause cracking of the outer fillet or even bending fracture. There are also some steel plates with high carbon content. If you choose In a hard state, bending will also cause the outer fillet to crack or even break, which should be avoided as much as possible.

The Material Influence Of Drawing Process


Sheet metal drawing, especially deep drawing, is one of the more difficult sheet metal fabrication processes. It not only requires the drawing depth to be as small as possible, the shape as simple as possible, and a smooth transition, but also requires the material to have good plasticity. , it is very easy to cause the overall distortion of the parts, local wrinkling, and even cracks in the stretched parts.

The lower the yield limit and the larger the plate thickness directional coefficient, the smaller the yield ratio σs/σb of the sheet, the better the stamping performance, and the greater the limit degree of primary deformation. When the plate thickness directivity coefficient>1, deformation in the width direction is easier than deformation in the thickness direction. The larger the R value of the stretch fillet, the less likely it will be thinned and broken during the stretching process, and the better the tensile properties will be. Common materials with better tensile properties are: pure aluminum sheet, 08Al, ST16, SPCD.

The Material Influence Of Stiffness


In the design of sheet metal structures, it is often encountered that the rigidity of sheet metal structural parts cannot meet the requirements. Structural designers often use high carbon steel or stainless steel instead of low carbon steel, or use hard aluminum alloys with higher strength and hardness instead of ordinary aluminum alloys , expecting to increase the stiffness of the part, in fact, there is no obvious effect. For the material of the same base material, the strength and hardness of the material can be greatly improved through heat treatment and alloying, but the change in stiffness is small, and the rigidity of the part can be improved. Only by changing the material and changing the shape of the part can a certain effect be achieved. , elastic modulus and shear modulus of different materials

The Main Way Of Sheet Metal Connection


In sheet metal fabrication, sheet metal parts must be connected and fastened in a certain way. The main methods of sheet metal connection can be welding, screw connection, riveting and bonding.

  • Welding – is a process method of local or overall heating of the weldment or plastic deformation of the weldment, or simultaneous heating and plastic deformation to achieve permanent connection, which can be divided into: manual arc welding, gas shielded arc welding, Laser welding, segment welding and contact welding, our main workers use gas shielded contact welding. 1.1 Gas shielded arc welding – During gas shielded arc welding, the electrode arc area and the welding pool are under the protection of shielding gas, and argon gas is used to shield the surface of the weld metal oxides and inclusions. Welding can be applied in any spatial position, and the forming process of welding can be observed and adjusted with the naked eye, and the production efficiency is high.
  • Contact welding – a welding method in which the joints are heated instantaneously during contact welding, and the welded parts are pressurized to form a welded joint in a molten or non-melted state. It can be divided into butt welding, spot welding and seam welding.
  • Threaded connection – Threaded connection has the advantages of easy local installation, convenient disassembly, and simple operation. It is often used in detachable steel structure connections. It can be divided into screw connection and bolt connection.
  • Riveting – riveting is a method of connecting parts or assemblies of metal structures with rivets. There are many types of rivets. Our commonly used rivets include closed round head blind rivets, closed countersunk head blind rivets and openings. Type round head blind rivets, open type countersunk head blind rivets.
  • Bonding – a connection method in which the desired connection is bonded together with an adhesive.
  • Plug-in – plug-in has the advantages of easy installation, convenient disassembly, and simple operation. Compared with other connection methods, the connection between the sheet metal parts can be completed by using the properties of the sheet metal parts without damaging the sheet metal parts themselves. material properties.
