The use of aluminum in automotive parts is growing rapidly. Aluminum plates used in the manufacture of car body parts in recent years, attention has been and automotive companies around the world, the advantages of using aluminum, enjoy. The main advantage of using aluminum to reduce vehicle weight. One of the main advantage of the aluminum sheet, how it differs from forming and forming of steel sheets. This article will provide tips on forming aluminum sheet.
Steel sheets, plates forming equipment for forming aluminum alloys are used. The amount of press tonnage required on aluminum plates, is less, but because Frmpzyry aluminum sheet forming lower surface running p ropes sensitivity running p ropes of Spring back more and more attention when in contact with the mold surface needs. To succeed in forming aluminum sheet according to the following points are necessary.
Controlling the flow of materials, good design using computer and numerical simulations forming process requires. Table 1 shows the overall dimensions and Blank templates is proposed. Note that these dimensions are general.
Bead design of important points in the design process of pressing sheets. Bead size and shape of the aluminum sheets used in pressing some water bead shape and size of steel sheets used in forming different. In cases where the plate slenderness is shallow (applications hood) is used in the form of a bead in the middle.
complete bead to stretch deeper as internal Panel Door is used. Very Shallow Prskaryhay well as pressing the lock bead of roof is used. The design of a steel bead that is done if the aluminum used can be caused Parhgy aluminum sheets.
Draw bead can be used to reduce the flow rate of material into the mold. By reducing the flow rate of materials, running p ropes the amount of additional Stretching instance is created. Draw bead to use and can be used on the overall design.
Center Lock bead should be placed at a distance of 24 times the thickness of the sides of the mold.
Since the elastic modulus of aluminum, steel one-third. Spring running p ropes back elastic behavior of the aluminum plates and steel sheets of different elastic back. Pressed steel tables that are used are not suitable for aluminum. Create at least 2.1 percent strain in the sheet to obtain the appropriate DR and stiffness is required. running p ropes Although using Bake hardenable material about DR, is independent of strain rate. To create a higher dimensional accuracy and predict strain levels in the Spring back plate should be uniform sheet.
Aluminum plates should be on the Blancking Clearance tool was accurate enough. Blade angle should be selected properly and the edges sharp and lubricant are made. Clearance of simple shear strength depends on the blanking die. The shear strength, decreasing to less clearance is required. For those with a shear strength of about 200MPa, Clearance rate of about 96 percent on each side, the thickness is recommended. For cases with shear strength greater than 200MPa, 9% of the material thickness is recommended. Shear strength of sheet aluminum alloy are presented in Table 2.
In Table 3, the pressure needed for pressing running p ropes various thicknesses of sheet aluminum alloy 1100 is presented. Other alloys using coefficients from Table 4 and Table 3 by multiplying the coefficients of the desired thickness can vary the amount of pressure needed to press thick plates made of other alloys of aluminum running p ropes can be achieved.
The blanking of aluminum, such as steel, to create an appropriate failure to punch through to about 45% of the plate thickness, is required. Blank lower level of the same amount, in the form of an intrusion. This creates a smooth and polished aspects of the Blank. Clearance of Burr leads to increased too much. Too low will cause uneven and Blank Parhgy the edges.
Binder for aluminum pressure is generally lower than that of steel. Variable binder force (Variable binder forcu) (VBF) can query capability during pressing to increase production. Figure 1 shows the amount of force (BHF) (binder holding force) binder is the strain induced in the panel. High risk, this figure indicates that the rate of non-immune running p ropes strain by a constant force on the binder has been developed and Nqthchyn Draw bead represents a strain rate of binder force during running p ropes the press has been created. running p ropes In addition push the binder, change, pressing this button while also pressing of the good or bad influence. running p ropes
Friction and wear behavior of a system specification, in forming Vrqhast. Friction in forming the contact pressure and sliding velocity depends. Specification running p ropes sheets and templates (mechanical properties, coating, surface roughness and geometry) and lubricant specifications and process conditions (eg, temperature) should also be considered. Also, the aluminum sheet, the surface texture is important (MF, EDT). When all the sheets with the mold surface forming aluminum sheet we consider the most important points that should be considered is to create a phenomenon called Galling. Wear Galling mechanisms in which the transfer of material from one surface to the other is done, for example, forming sheets of metal into a mold. This caused so much damage in S.
