6.3 Determination of assembly requirements

6.3.1 Dimensions deviation Use accuracy not less than ± 0.6mm steel tape, steel ruler measurement unit rack height, width and depth, which measures the difference between the value and the nominal value Is the appropriate limit deviations.

6.3.2 rail deviation

6.3.2.1 single rail straightness Using precision grade is not less than 2 square feet of 1000mm and a feeler, feet flat against the side rails, measured with a feeler largest room Gap is straightness per meter of a single rail.

6.3.2.2 The deviation from a single rail With steel ruler and accuracy not less than ± 0.5mm/5m level measurement, level meter to make adjustments on the horizontal side rails, water Flat line as a baseline to measure the distance to the rail multipoint baseline, within 1m of any difference between maximum and minimum values \u200b\u200bfor the single rail level deviation.

6.3.2.3 adjacent parallel deviation between two rail width Wherein a guide to baseline, measured on another rail from baseline to multi-point, any difference between the maximum and minimum 1m within the Parallel deviation between two rail width.

6.3.2.4 two adjacent horizontal rail height deviation With steel ruler and accuracy not less than ± 0.5mm/5m level measurement. Will be adjusted to a level of two horizontal rails Above the horizontal line as a baseline to measure the two opposing points to the guide rail from baseline, the absolute value of the difference between the height deviation, whichever A maximum of two guide rails height deviation.

6.3.2.5 rail height difference between the abutment With flat feet and a feeler gauge. The flat feet against the rail butt joint, with a feeler measuring the maximum gap is the difference between high and low rail butt joint.

6.3.3 column and the bottom of the vertical beam With a feeler Square top with the column gap delta '. Column and the bottom of the vertical beam according to equation (1) calculations. Is shown in Figure 2. delta = H · delta ' (1) Where. Degree delta

--- vertical column and the bottom of the beam, in millimeters (mm); H

--- high column, in millimeters (mm); delta '

--- Square and the gap to the top of the column, in millimeters (mm); h

--- Square height in millimeters (mm). figure 2

6.3.4 degree of difference The use of flat-foot steel ruler and measured.

6.3.5.1 The side panels and backs the abutment gap Using a feeler gauge measurements.

6.4.1 Determination of static load shelf According to GB/T 13667.1-2003

7.4 requirements, single-sided shelves on each shelf evenly distributed static load 400N, each double-sided shelves On a shelf uniformly distributed static load 800N, quality and accuracy of the load rating of ± 1%.

6.4.2 full static load measurement On each shelf plus uniform static load, load see GB/T 13667.1-2003 Table 8 of the load mass accuracy rating of ± 1%.

6.4.3 Load measurement run

6.4.3.1 shake the handle at full static load, so that the frame body running back and forth on the rails again, check the gear lever and the frame body processes run.

6.4.3.2 The hanging dynamometer crank handle on the movement of the handle along the tangential direction, hand dynamometer drive handle is turned, make a note of the standard rack column Starting dynamometer readings is cranking power and observe the operation. Test the handle clockwise and counterclockwise each do a test The result is the average of two determinations.

6.5 Determination of stability

6.5.1 dust load stability when the door is open Performed according to GB/T 10357.4 requirements.

6.5.2 dust load stability when the door is opened Performed according to GB/T 10357.4 requirements.

6.5.3 Loading shelf level stability Performed according to GB/T 10357.4 requirements.

6.6 Determination of structural strength

6.6.1 Test Equipment Structural strength test equipment should meet the following requirements.

a) structural strength testing machine. accuracy of the rated load power ± 5% (the structure is shown in Figure 3);

b) rangefinder. Range 0mm ~ 150mm, accuracy not less than ± 0.5%;

c) the weighing device. Range 0kg ~ 5000kg, accuracy not less than ± 1%. Table

7.3 Type inspection

7.3.1 type inspection timing When one of the following conditions, type of inspection should be carried out.

a) new products or old products to the plant production trial to identify stereotypes; B) after the official production, such as structure, materials, technology has drastically changed, it may affect product quality and performance;

c) Normal production, after regular or accumulate a certain yield, at least once a year type of inspection;

d) one year after the product discontinuation, resume production;

e) Settlement test results are quite different when the last type inspection;

f) Other types of inspection when required.

7.3.2 Type inspection items and sampling methods Type test items and the order will be as defined in Table 4. The same group in a test cycle, the same specifications of the product Randomly Take several parts assembled into a set of manual-intensive standard rack shelves and a column, and then do

5.1 in the set manually intensive bookshelf, Table 3 rails Progressive deviation, number of items 3,8 to 10 5.5.1,

5.5.2 project activity equipped with dust-proof door frame columns, other items in the standard rack Test the column.

7.3.3 determination principle Basic projects are qualified and general project failed no more than three items, the product is judged as qualified, otherwise unqualified.
