Cast Iron Test Platform

Rear axle suspension cast iron T-slot platform manufacturer
If the cast iron T-slot platform used by the customer is not easy to observe, it can also be identified by sound. The tempered product has a pleasant, crisp sound with a related echo. Enterprise users who have purchased can also test their purchased cast iron T-slot platform products, especially for some heavy-duty platforms. The method I recommend is very accurate. This method is also a convenient and direct approach. It should be installed in a well-ventilated, dry environment, away from heat sources, corrosive gases, and corrosive liquids.
Thickness and height are closely related to the platform's load-bearing capacity. The reinforcing ribs play a tensile role, and the height and thickness of the reinforcing ribs should be designed according to the load-bearing requirements of the cast iron T-slot platform. The height of the reinforcing ribs is usuallyhalf-rib, full-rib, and flat-rib. Regular periodic inspections should be carried out according to standards, with the calibration cycle ranging from 6 to 12 months depending on the specific situation.

Cast iron T-slot platform inspection method: The ratio of contact point area. Apply a developer on the inclined surface of the flat plate workpiece to be inspected, then rub it against a flat plate of no less than its accuracy grade. Clear contact points will appear on the flat plate to be inspected. Then use a transparent thin plate (such as a glass plate) with 400 small squares of 2.5mm*2.5mm within a 50mm*50mm range. Place it at any position on the working surface of the cast iron T-slot platform to be inspected, and observe the proportion of the area occupied by the contact points in each square (in units of 1/10).
The material requirements for the cast iron T-slot platform are also crucial. Generally, the material is HT200-3000, with a hardness of HB170-240. If the material meets the standard hardness, it will naturally be the same. The cast iron T-slot platform that has undergone tempering treatment is of good quality. It is inevitable for cast iron T-slot platforms to have minor sand holes and air holes. Generally, those within a reasonable range can be filled with cast iron material that is slightly softer than the same material hardness, which will not affect the accuracy. Scraping the Grade 1 platform to achieve the precision of the working surface of the cast iron T-slot platform is also a very important step.
Compared with other cast iron T-slot platform manufacturing processes, the cast iron T-slot platform manufacturing process has the following characteristics: The manufacturing and inspection processes for cast iron T-slot platform blanks are relatively complex. The cast iron T-slot platform blank is a thin-walled shell iron casting with a relatively complex structure. The casting requires a smooth surface, clear casting marks, and particularly, a dense structure. To meet the above requirements, a series of process measures should be taken when casting the cast iron T-slot platform, such as selecting molding materials with high refractoriness and controlling the moisture content of the molding sand; ensuring the hardness of the sand mold by compacting it layer by layer during molding; adopting a reasonable gating system and strictly controlling the pouring speed and temperature.
Sum the above proportions and divide by to obtain the ratio of the contact point area at the inspected location. To obtain typical values, the ratio of the contact point area should be measured at another location. Take the average of the two results. 6.2 Flatness fluctuation: Place the flatness fluctuation instrument on the working surface of the cast iron T-slot platform and move it along any straight line direction. The moving distance should be half the diagonal length of the flat plate and not less than 200mm. Take the difference between the maximum and minimum values on the indicator of the flatness fluctuation instrument (graduation value 0.001mm). This is the flatness fluctuation of the working surface of the flat plate to be inspected.
When inspecting workpieces on the cast iron T-slot platform, handle the workpieces gently and avoid moving rough workpieces on the cast iron flat plate to prevent磕碰, scratches, and other damage to the working surface of the cast iron T-slot platform. To prevent overall deformation of the cast iron flat plate, remove the workpieces from the cast iron flat plate after use to avoid long-term heavy pressure from the workpieces causing deformation of the cast iron flat plate. For machinery that will not be used for a long time, apply some butter and cover it with waste newspaper to prevent rust and protect it.
