Essential points of aluminum stamping analysis and stamping oil
June 10, 2022
The choice of aluminum and its alloy stamping oil is very important. It must ensure good lubrication, cooling, filtration and rust resistance. Therefore, the stamping oil that can be used for aluminum and its alloy processing is different from ordinary stamping oil. Choose one. The appropriate punch oil is necessary.
The choice of aluminum stamping oil Pouring stretching oil is a metal processing oil. It is suitable for ultra -high -intensity stretching, stamping and stamping molding, punching, pulling, etc. Pouring stretch stretch oil is divided into: water -soluble punch stretching oil, metal stamping stretch oil, aluminum stamping and pulling deep oil. 1. The lubrication of stamping and stretching oil: This is the most important performance of tensile oil. Instead of lubrication, it will cause workpieces to rupture, plate and metal sintering, product scratching, severe mold wear, and reduce mold life. 2. Cooling of stamping and stretching oil: There are many reasons for the heat of stamping processing. The friction heat and material plastic deformation heat between the mold and the material are all manifested in the form of processing heat. Especially when the processing shapes with complex processing shapes or materials with high resistance to plastic deformation, the heat generates greater the heat. When this kind of processing is performed for a long time, if it does not remove or suppress this heat, the calories are accumulated on the mold to make the mold make the mold make the mold so that the mold is made to make the mold make the mold make the mold. The temperature continues to rise, the mold further expands, the gap between the convex mold and the concave mold will decrease, the stress that friction and the application to the material will increase, and the local high temperature will cause the lubricant to break Fragmentation and other faults. In this case, through the use of water -soluble staminated oil, it can inhibit the calories generated, especially high -speed continuous action processing and high -speed continuous automation processing fields, as well as stainless steel pulled processing or high -speed processing of canas. Water capacitance oil. 3. Rust resistance of stamping and stretching oil: The parts after stamping are generally placed in the same way for a long time. In order to make it not rust during the placement period, the pull oil oil is required to have a good rust resistance. Because the stamping processing is very absorbability for lubricating oil, it maintains the oil membrane that is difficult to destroy on the metal surface, so it generally has a rust -proof effect. However, the effect of its effect is different according to the nature of lubricating oil and the processing conditions. In addition, the environment is different depending on the parts of the parts. Therefore, when the environment is severe and the storage time is long, the rust resistance of oil products is higher. 4. The oil welding of stress stretching oil: In order to simplify the sequence of the work order to improve production efficiency, it is required that the tensile oil has the performance that can be welded with oil welding without cleaning. Sometimes due to the attachment of the tension oil, rust is rusted in the welding place. Some oils produce harmful gases and affect the welding strength during welding. The above problems occur during stamping after stamping, which is very important for pulling oil. 5. The abandonability of stamping and stretching oil (easy to clean): Attach it on the stamping part to extend the oil. When cleaning the detergent and washing method that can be cleaned, the washing cost is low, and in a short time in a short period of time It is also one of the important features that can be survived. The cleaning part is not clean, which will affect the paint and electroplating of the post -process. 6. The operationality of stamping and stretching oil: Before stamping processing, the operation of the operation of the pull oil to the processing board requires time and labor, which is damaged to production efficiency. Therefore, this operation is easy to perform One nature. Especially for large -sized parts, this nature is particularly important. If it is operating, you should try to use low viscosity tensile oil as much as possible. For stamping molding processing, a large amount of heat will generate during the stamping process. The heat can deform the workpiece, which seriously affects the accuracy of the workpiece. Therefore, when choosing stamping oil, you must consider both lubrication and cooling performance, but also consider the pole pressure resistance of stamping oil. If the selected cutting pole pressure resistance is too low, the material may cause poor molding effect. Therefore, the stamping oil with good abrasion resistance is selected for refined pressure molding or ultra -precision stamping molding processing. In addition to considering the lubrication, cooling properties such as stamping oil, it is necessary to consider the resistance, cost and easy maintenance of stamping oil. The basic oil with relatively low viscosity oil is easy to use, and the grinding additives are added. However, the problem of the existence of stamping oil is low flash point, high temperature when stamping molding, easy to deform, high risk factor, and rapid volatile, user use costs have higher accordingly, so try to use pressure resistance and abrasion and abrasion under conditions permitted. Highly staminated oil. The use and maintenance of aluminum stamping oil 1) Aluminum stamping oil should be stored in a cool and dry place and keep the container closed to avoid mixing with water and impurities. The storage temperature should not exceed 60 ° C. 2) In order to ensure stamping effect, it cannot be mixed with other oils, and other debris is strictly prohibited.
