The invention discloses a two-way movement
cam shaping mechanism. The two-way movement
cam shaping mechanism comprises a
cam case, a cam spline housing is arranged in the cam case, a punch
assembly is arranged above the cam case and comprises a cover plate, and the cover plate is fixedly connected with the cam case through guide columns. A punch bottom plate is arranged below the cover plate, a
duralumin punch and pressing plate dies are arranged below the punch bottom plate, the punch bottom plate is connected with a lower module through a punch locating plate, lower
duralumin dies are arranged outside the lower module, the lower
duralumin dies are fixedly connected with a guide plate through a lower duralumin die pressing plate, a first roller base is arranged below the guide plate, and a first roller is arranged on the first roller base. The two-way movement cam shaping mechanism is characterized in that another punch
assembly is arranged below the cam case and comprises a bottom plate, a second roller base is arranged on the bottom plate, and a second roller is arranged on the second roller base; the second roller is tangent to a first cam; the first roller is tangent to a second cam. The two-way movement cam shaping mechanism can realize compacting and shaping of packing materials when a bubble cap
machine runs, compaction force can be freely adjusted, and insufficient pressure or excessive pressure is avoided.
