How to choose stamping and stretching oil? These 4 standards must be known!
October 03, 2023
In the stretching process, due to the high degree of stretching of the workpiece, we need to choose a stamping and stretching oil with good performance when selecting stretching oil. So what kind of stretching oil has good performance? Now let's introduce several methods for selecting stamping and stretching oil. Firstly, it has efficient wear resistance. When processing hard materials such as stainless steel, it is necessary for the stretching oil to have extreme pressure wear resistance in order to effectively ensure the integrity of the processed material and improve the work efficiency of the workpiece during the processing. However, some stretching oils do not have very good wear resistance, so when choosing, we must pay attention to the testing and selection of wear resistance.
Secondly, it has high viscosity performance, Stainless steel workpieces are particularly prone to sticking to the mold during processing, which can lead to stretching, damage, and wrinkling of the workpiece. Therefore, when selecting stamping and stretching oil, it is necessary to determine whether the viscosity performance of the stretching oil is excellent. Choosing a stamping and stretching oil with good viscosity can form a certain protective film in the workpiece and mold, forming a protective layer for both the mold and the workpiece, Improve the processing quality of the workpiece. Thirdly, it has efficient cooling performance, During the processing of workpieces, high pressure and friction can cause high temperatures. If cooling cannot be effectively obtained, the workpieces may deform, and poor cooling oil may become black. During the processing, black oil may adhere to the workpieces, which not only affects the subsequent processing of the workpieces, but also has a negative impact on the quality of the workpiece processing. Fourthly, it has the ability to reduce drawing force, Good stamping and stretching oil can reduce the drawing force of the equipment on the workpiece during processing and stretching, which is beneficial for improving the quality and effectiveness of the workpiece. When choosing stamping and stretching oil, we need to choose from the above standard points. At the same time, we also need to choose the appropriate stamping and stretching oil based on different equipment and processing materials. Do not choose low-quality stretching oil due to price factors. This not only does not help with workpiece processing, but may also affect the utilization rate and processing efficiency of workpiece materials during the processing, and even affect our brand image due to the quality of the workpiece.
