The compensation coefficient for the compensation of the rod pieces when pouring is one of the topics in the field of mechanical engineering. In the process of machine molding, the pouring of molten metal will produce certain geometric defects. In order to reduce this kind of geometric defect, it is necessary to add appropriate compensation coefficient to the rod component when pouring. The determination of the compensation coefficient requires technical personnel to study and analyze from the actual effect of pouring, which is a very complicated work.
Generally, in the process of pouring, the broader section is the target of compensation, the greater the compensation coefficient is. Therefore, the technical personnel needs to reasonably calculate the coefficient according to the size, proportion, material and other form factors of the rod component. At the same time, in order to ensure the control of the geometric dimension of the rod component, the compensation coefficient must be determined according to the size of the rod component and the degree of pouring of the molten metal.
On one hand, when the molten metal has a large degree of filling, the smaller the compensation coefficient should be, while on the other hand, it is necessary to increase the compensation coefficient appropriately when the melting degree is not high. In addition, correct calculation of compensation coefficient also needs to consider the layout of the components and the influence of curvature on the form accuracy. In this way, the form accuracy of the processed components can be improved, and the general engineering performance can be effectively guaranteed.
In short, when pouring molten metal, in order to achieve a reasonable degree of filling and the ideal form accuracy, the rod components need to be equipped with an appropriate compensation coefficient, so as to improve the overall working performance of the molten metal pouring machine and maintain the accuracy of the rod components. The determination of compensation coefficient is a very important work in the machine molding process, which requires the technical personnel to have a comprehensive understanding of the structural performance of the rod components so as to determine the compensation coefficient in an accurate manner.
