穿孔机是一种在纸带、卡片或其它材料上凿出各种组合孔用以记录(存贮)信息数据或符号的机器,在数据处理、工程控制与通讯等领域中已被广泛应用。但由于穿孔速度还远远不能满足这些领域的需要,故在一定程度上影响了通讯、数据处理的高速化。纯机械往复运动穿孔难以实现穿孔高速化。因为在穿孔过程中机械零件有较大的惯性,从静止到运动、从运动到静止都需要一定的时 Punchers are machines that drill various combinations of holes in tapes, cards or other materials for recording (storing) information data or symbols and are widely used in the fields of data processing, engineering control, and communications. However, since the perforation speed is still far from meeting the needs of these fields, it affects the speed of communications and data processing to a certain extent. Pure mechanical reciprocating perforation is difficult to achieve perforation speed. Because the mechanical parts in the perforation process has a larger inertia, from rest to movement, from exercise to rest need a certain time
