Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces FZ/T 92072-2006 "Pneumatic Pressing Brake". Compared with FZ/T 92072-2006, the main technical changes are as follows.
---Adjusted the classification and increased the marking and content of the cradle (see 3.1~3.2, Chapter 3 of the.2006 edition);
--- Increased the parallelism requirements of the cradle holding file, and added the notes and icons (see 4.1.1~4.1.3);
--- Increased the requirement of the fourth roller in the roving cradle for the first top roller in the main drafting zone (see Table 4 and Figure 4);
--- Adjusted the pressure range of the complete set of cradle (see 4.3);
--- Adjusted the pressure change value of the adjacent cradle adding and discharging pressure (see 4.4, Table 7);
--- Increase the dynamic fluctuation of the pressure of the cradle at the specified working position and working pressure (see 4.5, Table 8);
--- Cancel the pressure reduction requirement of the single set of cradle caused by repressurization of the whole vehicle after the pressure relief (see 4.8, Table 7 of.2006 edition);
--- Increased the requirements for the quality of the cradle manufacturing (see 4.7);
--- Added test methods and specifications (see 5.1, Figure 5 to Figure 7);
--- Increased the method of cradle sampling and the principle of judgment (see 6.3).
