Introduction to Cast Iron Platform Information

Cast iron welding platform, also known as cast iron flat plate or welding flat plate, is a reference plane equipment used for inspection, precision measurement, and marking in mechanical manufacturing. It is widely used in machine tool calibration, part inspection, welding assembly and other fields. Its material is mostly usedHT200-300 high-strength cast iron is treated with a dual process of artificial annealing (600-700 ℃) and natural aging (2-3 years) to ensure structural stability and wear resistance. The platform is divided into levels 0, 1, 2, 3, and precision planing according to national standards. The precision planing welded flat plate is the main procurement object in welding work, with specifications ranging from 100mm × 100mm to 3000mm × 6000mm, and supports customized production. The surface quality is inspected by coloring method, with a precision of no less than 25 contact points per 25mm ² at level 0, decreasing step by step.

This device includes a flat surfaceTypes such as T-slot, rivet welding, and 3D flexible welding platform. The five working faces of the 3D flexible welding platform are all equipped with grid marked holes for positioning, with high precision in plane, parallel, and vertical tolerances and hole positions, enabling precise positioning and combination of workpieces in infinite space. The working face is equipped with a permanent T-shaped groove for fixing workpieces, combined with scraping and grinding technology to ensure plane accuracy (such as reaching 3 μ m/1000mm at level 0). As a fundamental equipment in industrial measurement, assembly, and welding operations, its benchmark accuracy has a significant impact on product quality The application scenarios extend to fields such as automotive manufacturing, heavy machinery, and electronic testing, and installation requires leveling with shims（≤ 0.05mm/m) and regular rust prevention maintenance.

Structure and Technical Parameters

Cast iron welding platforms often use high-strength cast ironHT200-300， The hardness of the working face is HB170-240, which has been treated with manual annealing (600-700 degrees) and natural aging (2-3 years) to ensure stable accuracy and good wear resistance. The standard specifications range from 1000mm × 1000mm to 3000mm × 6000mm, and special specifications can be customized according to the customer's drawings.

The accuracy level is executed according to the national standard metrological verification regulations, usually divided intoThere are four levels: 0, 1, 2, and 3, as well as a "precision planing" level. The flatness error can be calculated according to the formula, for example, level 0 is 4 × (1+d/1000) μ m, where d is the diagonal length (unit: mm).

The 3D flexible welding platform is an important variant, with high-precision mesh labeled holes on all five working faces, and the side used for expansion or auxiliary positioning. Its plane, parallel, vertical tolerances, and hole position accuracy can ensure positioning and combination accuracy. Basic countertop size from1000mm × 1000mm to 4000mm × 2000mm are optional, and special sizes can be customized. When multiple tabletop combinations require precision, guide rails can be used for connection.

Installation, use and maintenance

During installation, the support should be supported at the main pivot point and the working surface should be leveled to the horizontal.

Precision debugging and cleaning of the working surface are required before use; The weight of the workpiece shall not exceed the rated load of the platform to avoid excessive collisions.

After use, it is necessary to clean the working surface in a timely manner and apply anti rust oil; If not in use for a long time, butter should be applied, white paper should be laid, and a protective cover should be added; Avoid using and storing in damp, corrosive, or warm environments.

Regularly inspect the accuracy of the platform, and restore it through debugging or scraping processes when the accuracy decreases; Under proper use and maintenance, both the accuracy of the working face and the platform body can be maintained for a long service life.

Standards and Quality Inspection

The accuracy and quality of the cast iron welding platform need to be guaranteed through inspection, which is a necessary step to ensure its accuracy and reliability as a measurement reference before use .

Coloring method (dot method)

The coloring method, also known as the spot test method, is a commonly used method for inspecting the flatness and contact spot distribution of cast iron platforms. When operating, mix the red lead powder and diesel evenly, apply it evenly to the surface of the platform, and then drag it on the platform surface with a ruler or inspection tool to observe the grinding situation and evaluate the surface error. According to the standard, the 0-level precision platform requires no less than 25 contact spots within a range of 25mm × 25mm.

Feeler gauge inspection method

The feeler gauge inspection method is a simple and effective method for detecting straightness and flatness errors. This method measures the straightness error of the working surface of the platform in various directions, and takes the maximum value as the flatness error of the platform. The feeler gauge inspection method is commonly used and simple, especially suitable for rapid inspection of small-sized cast iron platforms .

Level inspection method

The level verification method is suitable for quantitative evaluation with high requirements for flatness accuracy. When testing, first draw diagonal and grid lines on the working surface of the platform, and then use a composite level to measure and record data along each line at fixed intervals. Finally, based on the number of measurement steps, spacing, and platform size, the accurate flatness error value is calculated, and a platform flatness error curve can be drawn accordingly.

Surface quality requirements

The quality of the working surface of the cast iron welding platform directly affects its performance. According to the standard, the working surface should not have defects such as cracks, rust spots, scratches, dents, sand holes, pores, slag inclusions, shrinkage, etc. that seriously affect the performance of use. For platforms with dimensions greater than 400mm × 400mm, it is allowed to block sand holes with a diameter of no more than 15mm and a spacing of no less than 80mm using the same material, but the number of blockages should not exceed 6, and the hardness of the material at the blockage should be slightly lower than that of the surrounding materials. The platform in use allows for minor defects that do not affect accuracy .
