Technical Field
The utility model belongs to the technical field of metal hot die forging forming, and particularly relates to an edge cutting and punching composite die frame for hot die forging.
Background
The die carrier for the compound trimming and punching of the forge piece in the prior art mainly has two types: one is that the forging moves when trimming and punching, the trimming edge bush and the punching punch are fixed on the lower half part of the die carrier and do not move, the upper half part of the die carrier moves when working, and the forging is pushed by the upper punch to move to finish trimming; the second type is that the forging does not move when the edge cutting and the punching are carried out, and the edge cutting knife die and the punching punch are fixed on the upper half part of the die frame and move along with the movement of the upper half part of the die frame, so that the edge cutting is finished.
In the use process of the first type of die frame, the application surface is small due to the fact that punching waste is not easy to treat. The second type of die carrier is widely applied, but after the edge of the forge piece is cut, the forge piece is taken along with the edge cutting die, and the forge piece needs to be ejected every time. The common ejection mode is to finish discharging through a cross rod fixed on a lower die carrier, and the cross rod passes through a tool for fixing the edge cutting edge die and ensures that the upper half part of the die does not touch the discharging cross rod when moving, so the volume of the upper part of the die carrier is larger; in addition, the unloading mode cannot enable the die carrier to automatically feed from the side surface, and has certain limitation. The other discharging mode is that the discharging cross rod is fixed on a plurality of nitrogen springs, discharging is completed through spring force, and the forging piece can be contacted in each trimming and punching process in the discharging mode, so that the special-shaped forging piece is unfriendly, and the special-shaped forging piece is easily crushed in the using process.
