[0053] The structural principle or working principle of the sandblasting device for automobile radiator processing of this structure:

[0054] First, open the double-door box with window 103, and place one end of the heat sink body 400 in the first fixing block 213;

[0055] Then, the horizontal hydraulic cylinder 205 is started through the PLC controller 500.
