Riveting welding platform (riveting welding flat plate) manufacturer's specifications: **, (special specifications are made according to the buyer's drawings)
Riveting welding platform (riveting welding flat plate) manufacturer's use: suitable for welding of various workpieces, It is a reference plane for assembly and inspection work, and accuracy measurement. It is used as a benchmark for machine tool inspection and measurement to check the dimensional accuracy or shape deviation of parts. It is also an indispensable basic tool in mechanical manufacturing.
Riveting welding flat plate material and processing: Riveting welding flat plate, the welding flat plate material is high-strength cast iron H, the working surface hardness is HB, after two manual treatments (artificial annealing and natural aging), the accuracy of the product is Stable and good wear resistance.
Accuracy of riveting welding platform (rivet welding flat plate) manufacturer: It is carried out in accordance with the national standard metrology verification regulations, which are divided into five levels: The maximum area can reach meters long and meters wide
The maximum length of the riveting welding flat plate can reach meters long
The riveting welding flat plate can be specially customized by special users
Riveting welding platform (riveting welding flat plate) Manufacturer's precautions for use and maintenance
There should be no rust, scratches, bruises or other appearance defects that would affect use on the flat working surface.
There should be no casting defects such as sand holes, pores, cracks, slag inclusions and shrinkage porosity on the flat working surface. Each casting surface should be completely clean of molding sand, smooth and firmly painted, and all edges should be blunted.
On the opposite sides of the flat plate, there should be settings for mounting handles or lifting positions, threaded holes or cylindrical holes. When setting up the lifting position, consideration should be given to minimizing deformation caused by lifting.
The plate should be stabilized and demagnetized.
For riveted welding flat plates, the hardness of the working surface of the riveting welding platform should be HB or between.
, main verification items, riveted and welded flat plates, welded flat plate material and surface hardness. B. Shape and position tolerances, including nominal dimensions and verticality tolerances. ,Exterior. D. Flatness. , contact spots. , plane fluctuation amount. , allowable deflection value of the working surface. H. Surface roughness.
, riveting welding platform (riveting welding flat plate) manufacturer precision parameters.
Grade plates do not specify contact spot requirements. Grade riveted flat plates require that the number of contact spots should be no less than 1 point in any mm plane.
The number of contact spots required for grade riveted flat plates should be no less than 1 point in any mm plane.
