From the principle of motion, a flat forging machine belongs to a crank press, but its working part is to do horizontal reciprocating movement.At the same time, the flat forging machine has the characteristics of a hot die forging press, such as: the stiffness of the equipment is large, the stroke is fixed, and the dimensional stability of the forgings in the length direction (the direction of being hit) is good; the forgings are formed by static pressure when working, the vibration is small, and no huge foundation is required.The forging productivity on the flat forging machine is relatively high, and it is a kind of universal die forging equipment that has been widely used in mass production.
According to the different methods of die splitting, flat forging machines can be divided into vertical parting flat forging machines and horizontal parting flat forging machines.The concave die parting surface of the vertical parting flat forging machine is in a vertical position, and the die bore of several die forging steps of a forging piece is arranged up and down in the vertical direction. The operating conditions are poor, and it is more difficult to realize automated production; the die parting surface of the concave die of the horizontal parting flat forging machine is in a horizontal position, and the die bore is arranged in a horizontal direction. The bar is easy to move between the die bore, easy to realize automation, and the force of the fuselage is also relatively reasonable.Therefore, in recent years, horizontal parting flat forging machines have developed rapidly.
