Casting matters and process flow of cast iron platform

The cast iron platform is made of HT200 material, and the working face adopts manual scraping and grinding technology. T-shaped, V-shaped, U-shaped grooves can be machined on the working face, and circular and strip-shaped holes can also be drilled. Mainly used for workpiece inspection or marking, it is a flat alignment tool.

Production process flow:

1. Cast iron platform blanks: make drawings according to the technical requirements, make wood or foam shapes according to the drawings, mix, shape, dry, cast, drop sand, clean and inspect all parts of the blanks;

2. Mechanical processing of cast iron platform: appearance inspection and marking, workpiece on machine tool, processing, inspection, tempering;

3. Machine tool on cast iron platform, processed according to the drawing requirements, and sent to the inspection department for inspection;

4. Leveling of cast iron platform workpieces, manual scraping and grinding, and inspection by the inspection department;

5. Appearance treatment, painting, packaging, and warehousing of cast iron platforms.

Precautions for casting cast iron platforms: The control of the sand rolling process during casting and the properties of the molding sand will directly affect the quality of the measuring tool castings. Therefore, the molding sand should have good breathability, wet strength, flowability, plasticity, and yielding properties. Strictly follow the feeding sequence: old sand new sand clay coal powder water. The mixing time is set at 6-7 minutes, and after mixing, it takes about 5 hours to mix evenly. After blending, sieve and loosen the sand before use to make it loose and improve its permeability, flowability, etc. Control of casting and pouring process. Before pouring, the casting water should be treated with incubation and slag removal. During the pouring process, the flow should not be interrupted and kept stable to avoid sand holes caused by sand flushing. When running the fire, it is necessary to promptly block the parts that leak casting water and replenish the casting water to reduce defects such as cold insulation and insufficient pouring. The control of the casting cleaning process involves cleaning the measuring tool castings from the mold after cooling, in order to obtain surface defect free measuring tool castings.

Cutting machinability and reference surface of cast iron platform: In mechanical production, in order to stabilize the size of castings, they are often left at room temperature for a long time before cutting. This measure is also known as timeliness. But this type of aging does not belong to the metal heat treatment process. In the production of cast iron platforms, in order to prevent changes in size and shape during long-term use, the platform is often reheated to 100-150 degrees Celsius after low-temperature tempering and before precision machining for a certain period of time. This aging treatment is used to stabilize the quality of the platform.
