Problems solved by technology
[0004] Although the above tire film can be used to forge frame-type forgings; but when forging small-sized frame-type metal forgings, when it is necessary to form multiple grooves on the forgings, the blank is mostly forged first to form a frame. Then use the cutting device to fit the grooves of the frame. When the frame forgings bear gravity, this forming method will easily lead to breakage or cracks in the grooves of the frame forgings, which will affect the service life of the frame metal forgings.

The invention belongs to the technical field of forging processes, and particularly relates to a forming die for forging a frame metal forge piece and a forging forming method. A forging die cavity isformed in a forming die plate, and a plurality of mounting punching notches are formed in the side wall of the forging die cavity; a punching notch head is detachably mounted on each mounting punching notch, and a threaded cavity is formed in each punching notch head; a threaded rotating rod is in threaded connection in a threaded hole; one end of the threaded rotating rod is in threaded connection with a threaded cavity, and the other end of the threaded rotating rod is located on the outer side of the forming die plate; the threaded rotating rod is sleeved with an I-shaped pressing block, and the end of the I-shaped pressing block is attached to the upper end face of the punching notch head in an extruded mode; an extrusion ring is attached to the outer side wall of the I-shaped pressing block, and the extrusion ring is connected to the threaded rotating rod in a sleeving mode; the threaded rotating rod is in threaded connection with a locking nut, and the locking nut is attached tothe extrusion ring; and the stress and the strength of the side wall of the groove forged in the frame forge piece can be improved, and meanwhile, the forging forming precision of the frame forge piece is improved.
Description
technical field [0001] The invention belongs to the technical field of forging technology, in particular to a tire mold for forging frame metal forgings and a forging forming method. Background technique [0002] Only use simple general-purpose tools, or directly apply external force to the metal between the upper and lower anvils of the forging equipment, so that the blank can be deformed to obtain the required geometric shape and internal quality of the forging. It is called free forging. Many Free forging manufacturers use movable film forming on free forging equipment, which is called film forging. Compared with free forging, the forgings it forges have more complex shapes, more accurate dimensions, and are closer in shape to forgings. [0003] A Chinese patent discloses a tire mold for forging and a forging molding method for frame-mounted side forgings. The patent application number is: 2017113362292. The tire mold includes an upper tire mold and a lower tire mold, and...
