性能:锤头重80公斤,效率相当于65公斤气锤。结构:如下图。操作:用脚踩下脚踏板,通过拉杆拉动凸轮摇臂,从而推动前滚筒向后,挤紧锤头木板。靠后滚筒的转动,就可以使夹板锤头上升。松脚时凸轮退回原处,前滚筒被弹簧(这个弹簧图上看不见)推开,产生很大的空隙,于是锤头就可以自由落下锻制锻件。锤击的轻重,可以依靠脚踩踏板举锤高低来掌握。 Performance: Hammer weight 80 kg, the efficiency is equivalent to 65 kg hammer. Structure: As shown below. Operation: Foot pedal, pull the cam lever through the lever, thus pushing the front drum backward, squeeze the hammer wood. By the rotation of the drum, you can make plywood hammer up. When the loose foot back to the original cam, the front roller is spring (not visible in this spring) pushed open, resulting in a large gap, so the hammer can freely drop forging forgings. The severity of hammering, you can rely on foot pedal lift hammer to grasp the level.
