用于制造带拨销的偏心棘轮的铁基粉末模具及冶金装置
摘要：
一种用于制造带拨销的偏心棘轮的铁基粉末模具及冶金装置，由外侧面设有凸台的阴模、上冲、下一冲、下二冲和芯棒组成，所述阴模的中部开设有贯穿该阴模的模孔，所述下一冲穿设在所述模孔内，且该下一冲的上端面低于所述模孔上端面；所述下二冲穿设在所述下一冲内，且该下二冲的上端面低于所述下一冲的上端面；所述芯棒穿设在所述下一冲内，且该芯棒与所述下二冲平行设置，所述芯棒的上端面与所述模孔的上端面齐平；所述上冲内对应开设有用于所述芯棒滑动的通槽；所述模孔的内壁上开设有与偏心棘轮棘齿部分对应的齿槽，通过所述模孔的内壁，下一冲和下二冲的上端面以及芯棒的柱体的外表面在所述阴模中构成用于制造偏心棘轮的模腔。
摘要（英）：

An iron-based powder die for manufacturing an eccentric ratchet wheel with a shifting pin and a metallurgy device are composed of a female die with a boss arranged on the outer side face, an upper punch, a first lower punch, a second lower punch and a core rod, a die hole penetrating through the female die is formed in the middle of the female die, the first lower punch is arranged in the die holein a penetrating mode, and the upper end face of the first lower punch is lower than that of the die hole; the second lower punch is arranged in the first lower punch in a penetrating mode, and the upper end face of the second lower punch is lower than the upper end face of the first lower punch. The core rod is arranged in the first lower punch in a penetrating mode, the core rod and the secondlower punch are arranged in parallel, and the upper end face of the core rod is flush with the upper end face of the die hole; a through groove for the core rod to slide is correspondingly formed in the upper punch; tooth grooves corresponding to ratchet parts of the eccentric ratchet wheel are formed in the inner wall of the die hole, and a die cavity used for manufacturing the eccentric ratchetwheel is formed in the female die through the inner wall of the die hole, the upper end faces of the first lower punch and the second lower punch and the outer surface of the cylinder of the core rod.
