Storage shelves in Shandong province product quality inspection
(1) size of shelves and parts inspection standards: The normal size range of shelf units: 5mm,-2.5mm; Slightly substandard size range: 5mm size ≦ deviation < 8mm;-2.5mm ≦ size deviation <-5mm; serious substandard size range: 8mm size ≦ deviation; -5mm size ≦ deviation; Inspection method: storage shelf unit thickness of the samples, thickness range: ± 0.02mm NET feet; 0.06~0.08mm is out of range of spraying thickness considered incorrect material. Installed in each part forming a complete set of shelves, according to the agreed size of drawings to measure their parts. 2. the storage shelves and Visual inspection: Qualified storage shelves: the overall effect a reasonable appearance, looks clean, no debris, no color, no stains or scratches, the punching and bending parts clean and smooth, Burr-free. Slightly defective products: reasonable overall effect, appearance is not obvious stains or scratches, chromatic aberration is not obvious, the punching and bending parts is not particularly neat, no obvious glitches. Seriously substandard products: total effect unreasonable, appearance is damaged, has obvious stains or severe scratches, color clear, punching and bending parts of irregular Burr obviously seriously ill.
Storage shelves the appearance of test methods: A, shelves installed, Visual shelves after the completion of the overall effect; B combination, the shelf is put by construction drawings completion, number corresponds with the drawings that the location is correct, observe the overall compatibility combo rack, beautiful, floor levels, overall height and width of the shelves are the same. C, through more than one perspective on the shelf spray the surface is smooth, whether there are stains, scratches, and there is no color. D punching or bending, Visual shelves tidy and without burrs. 3. shelves installation structural testing: Qualified storage shelf shelves placed upright, solid, don't shake when appropriate external no distortion, no dumping, not serious jolt; installing solid, easy off, easy disassembly; after the exhibition of goods shelves to be steadier, not italic, not welding. Unreasonable structure: shelves after placing tilt, shake, easy pour, unstable parts easy to shed, show serious shelf after shaking, distortion, welding, easy to pour. 3.4.2 check method a good shelf upright, solid, Visual emission, check the suitability of the various components, disassembly and Assembly convenience; b, moderate by hand shake shelves, observe whether the shelves shook clear, easy to pour. C, such as customers with the first exhibition of goods goods, observe the shelf stability and load-bearing, check that the shelf is tilted, whether weld, if the part is loose and easy dropping. 4. shelves and components weight measurement: Weight is a measure of the shelf the shelf materials used meet the requirements of a practical approach, we often pass the test material thickness to determine if the materials meet the requirements, but the finished product contains shelves thickness the thickness of the material and thickness of spray powder, and thickness of spray powder, customers are often difficult to test, so shelves weighed by formula to calculate the thickness of the material is relatively accurate. Rack weight formula: weight shelf shelf materials used = proportion of area number * material * thickness * Note: iron weight: 7.85.
