The foundry industry ofbronze sculpture in the Han Dynasty differed in nature
form the bronze sculpturein the peak of Shang and Zhou of the Bronze
Age.
Stable and reliable performance on the PLC control program can be
compiled by themselves, as long as the correct handling of communication between
a good PLC and CNC control requirements can be achieved, the program can be
divided into two steps to achieve the bronze knife library rent first position,
and then the fine positioning. The bronze sculpture in more areas followed the
features of Warring States Period and Qin. First step is to let the bronze
knife library to locate. that is, according to the part program requirements
Bronze knife library should go to wrap a number of bronze knife device and its
control by the PLC program to calculate the angle of rotation of the bronze
knife library and notify the CNC Click to the value of the running of library of
bronze knife.
CNC control bronze knife library running in place, immediately
notify the PLC, bronze knife library coarse positioning is completed. The second
step is to make the bronze knife library fine positioning when the rough
location of the PLC received a CNC issued a bronze knife library in place
signal, the PLC immediately begin to compare the output values of the two fine
positioning switch and notify the CNC low-speed operation of a bronze knife,
until the fine positioning in place from the above analysis, in terms of
hardware or software, or speak from the control technology can achieved, so the
program is feasible. Dynasties filled in the bronze sculpturein the same kin by
degrees. the bronze knife positioning control of the library hardware is a
bronze knife library fine positioning sensor switch selection of fine
positioning accuracy is relatively high, so the choice of the German Baruch
Cardiff produced by sensor switch.
The maximum output current of 10mA
(minimum lmA) of such switches with high sensitivity, strong anti-interference
performance, with a linear amplification performance requirements of the
operating temperature a l The 00C - +600 C. 2. fine positioning switch
installation of two fine positioning switch installation is very particular.
requirements installed slight change can cause the output of the two switches in
mechanical have a greater change in position the two switch sensor surface is a
cylindrical surface of the circular bronze pocket Besides, with the development
of lacquer and pottery, the bronze sculpturewere replaced. cylindrical surface
of the two sensor switch is relatively bronze adjustable distance, while the
relative position between the two adjustable to ensure its high sensor
sensitivity.
