Description
Technical field
This utility model belongs to forging process equipment technical field, particularly relates to a kind of high stability noise reducing type forging hammer.
Background technology
Forging equipment refers in forging processing for the plant equipment shaped and separate.Forging equipment includes shaping
Forging hammer, punching machine, hydraulic press, fly press and horizontal forging and upsetting machine, and forging manipulator, uncoiler, arbor press, cutter
Etc. auxiliary equipment.Wherein, forging hammer is to utilize the drive mechanism such as air pressure or hydraulic pressure to make to fall part, including piston, hammer stem, tup,
Upper anvils etc. produce motion and accumulate kinetic energy, are applied to forging in the extremely short time, are allowed to obtain plastic deformation ability, complete various forging
The metal forming machinery of pressure technique.Existing forging hammer also exists many deficiencies, such as, poor stability in use process, forging hammer body under
Not having guide frame during falling, shift phenomenon easily occur, this is mainly due to producing the biggest hitting power in forging hammer dropping process,
And the reverse impact power that tup is produced by forging is the biggest, irregularly forge face when tup clashes into forging, then reverse impact power is not
Straight up, the most still there is the power of a skew, forging hammer body so can be caused to produce bigger biasing force, make
Obtain forging hammer body and shift phenomenon easily occurs.
In order to solve the problem that prior art exists, people have carried out long-term exploration, it is proposed that solution miscellaneous
