Capture of foreign matter from the press for forming a cathode ray tube panel

摘要

In order to prevent the shell (51) and butum die (52) in the cathode-ray tube panel shaping press to cool down, the cooler flowing into the cooler and the lifting and lowering of the memory (54) lead to the poor panel shaping caused by the inflow of metal powder,The magnetic capture means (1) is set on the press to collect the metal powder,The capturing means (1) described above are the metal powder generated in the flap plate (58) of the memory (54) in which the plunger (53) is installed, the metal powder generated when the flat plate (53) is inserted into the shell (51) and butum mold (52), and the metal powder generated when the flat plate (53) is inserted into the shell (51) and butmal (52) The first and second foreign matter catching means (2 and 3) which can prevent the inflow into the mold (52) are set, so as to reduce the poor shaping of the panel.
