Traditional sand casting mostly constructs the mold cavity and core seat through wood mold or metal pattern. It has an important impact on the geometry, dimensional accuracy and surface roughness of the casting, and is directly linked to the production efficiency and cost of the casting. The pattern and...
FE2 has eliminated the internal defects of the casting by increasing the edge-pressing riser. However, due to the increase of the quality of the riser, the amount of molten iron that needs to be melted in the casting process will increase, which will affect the carbon efficiency of the...
We will continue to explore the characteristic carbon benefit model of process design and the optimization and application of its parameters. Taking the pouring characteristics of a base casting as the research object, the casting is mainly used for the setting of roadblocks and road signs in road traffic....
Taking the traditional sand casting process design as the object, this paper mainly studies the process carbon benefit modeling and parameter optimization of sand casting process design characteristics, but in the casting process, carbon emissions and resource consumption are affected not only by the characteristics of process design, but...
The process parameters related to the characteristics of sand casting process design are taken as the optimization object, and the carbon benefit is taken as the optimization goal, so as to improve the sustainability of the casting process to a certain extent. On the basis of ensuring the forming...
In order to effectively analyze the comprehensive benefits of carbon emission, production time and resource cost of foundry enterprises, the carbon benefit model is introduced through the established quantitative model of carbon emission, production time and resource cost under the influence of process design characteristics, as shown in the...
Traditional sand casting often has design limitations in process, especially for the forming of complex castings, the differences of casting structure, casting sand heat transfer coefficient and shrinkage are easy to lead to casting defects. Therefore, relevant scholars put forward the concept of multi-material composite mold to study the...
The z-axis is selected as the prospective control axis to verify the effect of five axis linkage speed control. Take the limit value of forward and reverse speed of each axis equal, set the electronic gear ratio and pulse frequency division of each axis servo driver respectively, so that...
In the process of five axis machining, due to the large amount of data, the control system can not carry out a lot of inverse RTCP calculation in advance, and the motion speed can only be calculated according to the programmed coordinates. Based on this principle, when using five...
The three-dimensional modeling of impeller sand mold is carried out by UG, and the automatic cutter shaft machining mode is selected in cam module. The machining strategy is from the coated cylinder to the wheel hub, the blank size is 337mm × 337mm × 166mm, the cutter diameter is...
