DEVICE FOR DUST-PROOFING LOWER STAMP OF ROTARY TYPE POWDER COMPRESSION FORMING MACHINE

摘要

PURPOSE:To perform the assembly and disassembly of a lower stamp dust- proofing device without using any bolt by providing a seal pressing plate of the inside of a lower stamp through hole in the radial direction of a rotary panel along the upper face of a lower stamp fitting part with its insertion and removal capably. CONSTITUTION:After holding plural dust-proofing seals 20 by fitting into the lower stamp through hole 22 of a seal pressing plate 19 this plate 19 is inserted toward the center side of the rotary panel 11 along the upper face of a lower stamp fitting part 14 from the outside of the rotary panel 11. The insertion of this seal fitting plate 19 is stopped with the fitting part 23 of the both ends thereof being respectively fitted to a stopper 18. The dust-proofing seal 20 and a lower stamp sliding hole 16 are roughly located. Finally, the lower stamp 17 is inserted upwards against the lower stamp sliding hole 16 of the rotary panel 11 to insert the upper part thereof into the dust-proofing seal 20. With this insertion the dust-proofing seal 20 is subjected to automatic aligning correctly by being moved so as to become co-axial with the lower stamp 17 according to the seal pressing plate 19 which is not fixed.
