Multiple hammerheads (2, 3, 4, 6 or 8) are arranged radially and evenly in the direction perpendicular to the bar stock axis, and the hammer heads make synchronous radial movements to centripetal strike the bar stock. At the same time, the bar stock makes a feeding motion in the axial direction, and rotates or does not rotate as needed. After being hit by the hammer, the cross-section of the bar stock is reduced and the length is elongated. Therefore, radial forging is basically to complete the process of shrinking, drawing or extending the forging process, and make the forgings obtain a certain size and profile.
The radial motion of the hammerhead consists of two movements: one is the reciprocating strike motion and the other is the radial feed movement. The reciprocating strike movement is generally a high-frequency small-stroke movement, mainly the blank is compressed to deform it, and the radial feeding movement is mainly to make the forgings obtain a variety of different diameter sizes, and the method is to adjust the position of the front dead center of the reciprocating strike movement relative to the forging axis. The radial feed movement is carried out according to the process arrangement when required during the forging process. In some machines for specific purposes, this movement is not available, or it is only pre-adjusted before the machine is working.
When the forging is a cylindrical surface (with steps or without steps), the radial feeding movement and the axial feeding movement are alternately carried out, when the forgings are cone, and the cone surface is longer than the forming surface on the hammerhead, the radial feeding movement is often carried out simultaneously with the axial feeding movement at a certain speed proportion.
