Forging hammer is a kind of mechanical equipment which works on the blank material and makes it plastic deformation by the mechanical energy caused by the heavy hammer falling down or forcing the high speed fitness movement. Forging hammer is the most common, the longest history of 10 tons of high-speed punch forging machinery. It is simple in structure, easy to work, wide in application, easy to repair, suitable for free forging and free forging. But the vibration is very big, it is difficult to complete the automatic production. Mechanical press is made of crank connecting rod or elbow rod organization, CAM mechanism, extruder screw organization transmission system, stable work, high precision work, 80 tons of high-speed punch actual operation standard is good, high production efficiency, easy to complete the mechanical automation, automation technology, suitable for work in the automatic production line. Mechanical presses rank first in total number of all kinds of forging and pressing machines. Cold heading machine and other various cable forming automaton, flat forging machine, screw press, axial forging machine, most steel bar bending machine, correcting machine and cutting machine, etc., also have similar transmission mechanism with mechanical press, can be said to be the successor of the mechanical press series products. Hydraulic press is a high pressure liquid (oil, emulsified oil, etc.) to transfer the working pressure of forging machinery. The travel arrangement of the hydraulic press is variable, and the larger working force can be transmitted at random parts.
