Abstract
Description
technical field
[0001] The invention relates to a forging equipment, in particular to a high-speed pneumatic forging hammer device. Background technique
[0002] At present, the forgings of automobiles, diesel engines, tanks, heavy vehicles, and heavy machinery are all produced by steam hammers or hydraulic hammers, and heavy presses. Among them, the liquid air hammer must increase the volume of the lower chamber because the lifting speed of the hammer is too slow. When the cylinder diameter cannot be increased, the diameter of the hammer shaft can only be reduced; because of the above, when forging irregular size forgings, the hammer head A very strong torsional moment will be generated in an instant, and the thinned hammer shaft is easy to bend and twist; in order to eliminate the influence of the hammer head on the hammer shaft, the hammer head and the hammer shaft are connected by a ball head. The advantages of rigidity and precision of the forging hammer are gone, and ...
