Cast iron platform, also known as cast iron plate, clamping platform, is used in the industrial field for workpiece testing, scribing, assembly, welding and other operations of the important foundation of the gauge, with its high precision, high stability and durability, has become an indispensable tool for machinery manufacturing, mold processing, automotive industry and many other industries.
From the point of view of material and structure, cast iron platform is mainly made of high-strength gray cast iron or ductile iron casting. Gray cast iron because of good casting performance, shock absorption and wear resistance, become a common material for cast iron platform; ductile iron is with higher strength and toughness, suitable for the higher requirements of the load-bearing capacity of the scene. The surface of the platform is finely processed, and commonly available in the form of flat surface, T-slot surface and grid slot surface. Plane platforms are used for general workpiece inspection and marking; T-slot platforms can be fixed with bolts and pressure plates to facilitate machining and assembly; mesh slot platforms are suitable for multi-angle positioning and measurement of complex workpieces. The bottom of the platform is usually designed with reinforcement structure to enhance its rigidity and deformation resistance, to ensure that under heavy load conditions can still maintain stable accuracy.
The high precision and stability of the cast iron platform comes from its unique manufacturing process. In the casting process, by strictly controlling the iron composition and pouring temperature, to reduce casting defects; castings need to be aging treatment after molding, will be placed in a natural environment or heat treatment furnace, to eliminate internal stress, to prevent deformation in the later use. After rough machining, the platform surface is then scraped, ground or mechanically milled and other finishing processes, so that the flatness, surface roughness and other precision indicators to meet national standards. Take the 0 level precision cast iron platform as an example, its flatness error can be controlled at the micron level, providing a reliable benchmark for precision measurement and processing.
In practical application, cast iron platform has various functions. In the machining shop, it is the reference plane of workpiece marking, technicians through the height ruler and other tools on the platform to mark out the machining contour line, to ensure the precision of workpiece dimensions; in the product testing process, the platform as a measurement reference, with the percentile meter, micrometer and other instruments, the flatness, parallelism, perpendicularity, and other shape and positional tolerances of the workpiece to carry out accurate testing; in the mold manufacturing and assembly process, cast iron platforms provide a stable support for the assembly of mold parts, to ensure the accuracy of workpiece size. In the process of mold manufacturing and assembly, the cast iron platform provides stable support for the assembly of mold parts and guarantees the assembly precision of the mold. In addition, in the production of automotive parts, aerospace precision machining and other fields, cast iron platforms also bear the key positioning and calibration tasks.
With the development of industrial automation and intelligent manufacturing, cast iron platforms are also constantly innovating and upgrading. On the one hand, through the introduction of CNC machining technology, to improve the platform's machining accuracy and production efficiency; on the other hand, combined with new materials and new processes, to develop a corrosion-resistant, high temperature-resistant special cast iron platforms to adapt to more complex industrial environments. At the same time, the intelligent transformation of cast iron platforms is also advancing, such as the integration of sensors to achieve real-time monitoring of the platform status, to provide support for the digital transformation of industrial production.
