Aluminum profile inspection platform

The aluminum profile inspection platform is a platform for checking the parallelism of aluminum profiles and is a production tool for aluminum profile manufacturers.The external dimensions of the aluminum profile inspection platform are generally between 300mm x 3000mm and 600mm x 6500mm,so the height should be maintained at 300mm or above.

The aluminum profile inspection platform and aluminum profile inspection plate have similarities with general cast iron platforms,but there are also differences.The difference lies in the structure of the platform.If the weight bearing capacity of a general cast iron platform is not very large,the panel and enclosure can be made slightly thinner,which can save costs.However,aluminum profile inspection platforms and aluminum profile inspection plates cannot be measured in this way.

The characteristics of the aluminum profile inspection platform:

1.Above is a flat surface,manually scrape the flatness of the upper surface.

2.Specifications:500*6000600*6000(The specifications are made according to the buyer's drawings.)

3.Accuracy:According to the standard metrological verification regulations,it is divided into four levels:0,1,2,and 3.

4.Material:The working surface hardness of cast iron HT200-300 is HB170-240.After two manual treatments(artificial annealing at 600-700 degrees and natural aging for 2-3 years),the product has stable accuracy and good performance.

The aluminum profile inspection platform is sometimes used in conjunction with the assembly line,which may suffer from impact force.The supporting frame should be stable,and the surface thickness of the platform should also be strengthened.

Common defects and analysis of aluminum profile inspection platforms:

1.Characteristics of oxidation slag inclusion defects

Oxidized slag is mostly distributed on the upper surface of the casting,at the corners where the mold is not ventilated.The fracture surface is mostly gray white or yellow,which can be found through X-ray or mechanical processing,as well as during alkaline washing,acid washing,or anodizing.

Reasons for occurrence:1.Unclean furnace material and excessive use of recycled material.2.Poor design of pouring system.3.Unclean slag in alloy liquid.4.Improper pouring operation,resulting in slag inclusion.5.Insufficient standing time after refining and metamorphism treatment.

Prevention methods:1.The furnace material should be blown with sand,and the amount of recycled material should be appropriately reduced.2.Improve the design of the pouring system to enhance its slag blocking ability.3.Use appropriate flux to remove slag.4.During pouring,it should be smooth and attention should be paid to slag blocking.5.After refining,the alloy liquid should be left to stand for a while before pouring.

2.Characteristics of Pore and Bubble Defects

The pores inside the walls of three castings are generally circular or elliptical,with a smooth surface and usually shiny oxide skin,sometimes appearing oil yellow.Surface pores and bubbles can be discovered through sandblasting,while internal pores and bubbles can be discovered through X-ray or mechanical processing.

The reasons for the black appearance of pores and bubbles on X-ray film are as follows:1.The casting alloy is unstable and gets caught in gas.2.Impurities(such as coal shavings,grass roots,horse manure,etc.)are mixed into the mold(core)sand.3.Poor ventilation between the mold and sand core.4.Shrinkage on the surface of the cold iron.5.Poor design of the casting system.

Prevention method:1.Properly control the pouring speed to avoid getting caught in gas.2.Impurities should not be mixed in the mold(core)sand to reduce the gas generation of the molding material.3.The exhaust capacity of the core sand.4.Correct selection and treatment of cold iron.5.Improve the design of the pouring system.
