Aluminum products have relatively strong plasticity, and they can be processed into various shapes by machinery and equipment. Taking stamping as an example, from the mold design point of view, there are single punch, composite, continuous, and from the depth point of view, there are plane punch, semi-shear, shallow stretching, and deep stretching.From the technical point of view, there are stamping, bending, rounding, shrinking, etc.

Ordinary punching, grooving, and blanking can use ordinary gear machines, such as domestic machines or Shanghai second forging machines. For precision stamping, pneumatic presses should be selected. It is best to choose a new machine with stable performance. The tolerance range will be small; if the continuous stretching die is stamped, pneumatic and the tonnage should be relatively large. The stable performance punch is used to punch, and the position space of the mold should be long and high. For continuous stamping, the material belt is continuously stamped through the mold, from micro-stretching, shallow stretching, deep stretching, and finally blanking forming, which is generally completed in many steps. Take the stretched aluminum tube of an electronic cigarette as an example. For aluminum pipes with a cross-section size of 20X10MM, a wall thickness of 0.5MM, and a height of 90MM, a pneumatic punch of more than 110 tons needs to be selected for stamping. The mold needs to go through more than 20 steps to complete a blank, and then after blanking, it is cut according to the actual size of the product, or the finished product size is completed by CNC engraving. Although the product is small, the punch should choose a large tonnage, some large products, thin materials, you can also choose a small punch for stamping, stamping technology according to different products design different molds, choose different presses, some speeds have to be opened very quickly, and some are processed by CNC precision engraving. The size of the finished product, although the product is small, the punch should choose a large tonnage, some large products, thin materials, you can also choose a small punch for stamping, stamping technology according to different products design different molds, choose different presses, some speed is very fast, some The speed is very slow, and the process can be described as complicated.The tonnage of the punch is generally 0.5 tons, 1 ton, 2 tons, 8 tons, 16T, 25T, 40T, 63T, 80 tons, 110 tons, 150 tons, 200 tons, etc., there are domestic and imported, small products with thin materials use small presses for single punching, and large presses for stretching. For large products, large tonnage presses must be used for thick materials, and the size of the punch is directly related to the thickness of the material and the material itself. Take aluminum plate as an example. If the aluminum plate is 1.0MM thick, the minimum can only be 1 punch. For round holes above.0 MM, it is easy to break the needle by punching small holes with thick material.If it is a 1.0MM thick iron plate, only holes above 2.0MM can be punched, otherwise it is easy to break the punch needle and cause the mold to be scrapped.
