小型冲切机是我厂工人同志们自己设计和制造的。它的特点是构造简单,造价低廉,通用性大。适用于成批或小量生产的工具、试制或修理车间。机器结构如附图所示,动力由电动机9用三角皮带7,传给曲轴1,使曲轴1转动。曲轴1转动,带动连杆2作上下往复运动,上刀刃4也随着做上下往复运动。5是下刀刃,把材料连续地送入上下刀刃刃口中间,就可以冲切出各种形状的零件。6是机架,用12亳米厚的钢板和12号工字钢焊合而成。导套3的作用是控制上刀刃,不让它转动。底板17,用来支持机架。11和13是球面轴承,支架14把曲轴1支撑住。
Small punching machine is my factory workers comrades design and manufacture of their own. It is characterized by simple structure, low cost, versatility. Suitable for batch or small-scale production of tools, trial or repair workshop. The structure of the machine is shown in the attached drawing, the power is transmitted to the crankshaft 1 by the V-belt 7 of the motor 9, and the crankshaft 1 is rotated. The crankshaft 1 rotates to drive the connecting rod 2 to reciprocate up and down, and the upper blade 4 reciprocates up and down along with it. 5 is the next blade, the material is fed continuously into the middle of the upper and lower blade edge, you can punch out a variety of shapes of parts. 6 is the frame, with 12 mm thick steel and 12 I-beam welded together. The role of the guide sleeve 3 is to control the upper blade, do not let it rotate. Floor 17, used to support the rack. 11 and 13 are spherical bearings, the support bracket 14 crankshaft 1 live.
