Cast iron platform is widely used in heavy industry for inspection, welding, assembly, detection, measurement, bench marking, etc. Cast iron Flat Taiwan is a general name in the industry. There are many subcategories under it. The names are strange and the uses are also exquisite,
Jingxiang cast iron platform casting It has the comprehensive function of strength, hardness and resistance cooperation, and also has a variety of special functions, such as wear resistance, high temperature and low temperature resistance, corrosion resistance, etc. Good plane invariance and resistance, good rigidity, no deformation; The working surface has high smoothness, no casting defects such as sand holes, air holes, shrinkage porosity, etc. The bottom stiffener is flat and straight, with strong tensile resistance, long service life, and excellent mechanical and physical functions.
Cast iron platform is used for Testing equipment , assembly, scribing, etc. for plane datum Measuring tools 。 In order to ensure the accuracy of the cast iron platform, it is necessary to understand these matters. Generally, the cast iron platform uses high degree cast iron HT200-300 with hardness of HB170-240, which can meet the national standards. During the production of cast iron platform, tempering shall be carried out, and annealing treatment shall be carried out at a high temperature of 600-700 degrees, so as to increase the precision of cast iron plate. According to the insiders, the natural aging of cast iron platforms that generally meet the national standard is 2-3 years, but in many cases, under the influence of funds, most of them will replace aging with vibration exciters.
During the production of cast iron platform, in order to ensure the quality and accuracy of measurement, great attention should be paid to each production link. From the initial drawings and the selection of cast iron slab blanks to the top Machine tool There are many main things in the process of leveling, inspection and processing of workpieces.
Cast iron platform surface and internal quality requirements:
1) Cracks, shrinkage porosity and other defects affecting the service performance of castings are not allowed.
2) The surface of the casting shall be free of cracks, inclusions, unevenness, holes, sand and other defects, and the flash, burrs, sharp corners and oxide skin shall be removed. Make it meet the drawing requirements.
Cast iron platform processing requirements.
1) The finish of the machined surface shall be up to or better than Rz6.3.
2) Sharp corners and burrs shall be cleaned.
Packaging requirements for cast iron platform: medium thick plywood wooden box packaging, to ensure that it is suitable for automobile transportation and sea transportation.
The surface quality of cast iron platform is inspected by coloring. Grade 0 and Grade 1 flat plates shall have at least 25 points within 25 mm2 on each side, Grade 2 shall have at least 20 points, Grade 3 shall have at least 12 points, and the specification of cast iron platform shall be 200 × 200-2000 × 4000 (special specifications shall be made according to the drawings of the demander).
