Description
Technical field
The invention belongs to forging process equipment technical field, particularly relate to a kind of forging die device
Forging hammer assembly.
Background technology
Forging equipment refers in forging processing for the plant equipment shaped and separate.Forging
Manufacturing apparatus include shape forging hammer, punching machine, hydraulic press, fly press and
Horizontal forging and upsetting machine, and the auxiliary equipment such as forging manipulator, uncoiler, arbor press, cutter.
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 anvil etc. produce motion and accumulate kinetic energy, are applied in the extremely short time
Forging, is allowed to obtain plastic deformation ability, completes the metal forming machinery of various Forging Technology.Existing
Some forging hammers also exist many deficiencies, such as, poor stability, forging hammer body in use process
Not having guide frame in dropping process, shift phenomenon easily occur, this is mainly due to forging hammer
Dropping process produces the biggest hitting power, and the reverse impact power that tup is produced by forging
The biggest, irregularly forge face when tup clashes into forging, then reverse impact power vertically to
On, the most still there is the power of a skew, forging hammer body so can be caused to produce
Raw bigger biasing force so that forging hammer body easily occurs shift phenomenon, and existing mold leads to
Cross drift to be fixed on forging hammer, but the vibrations that forging process produces are relatively big, use this
Fixing means is fixed, and mold easily departs from from forging hammer, there is bigger safety
Hidden danger.
In order to solve the problem that prior art exists, people have carried out long-term exploration, have carried
Go out solution miscellaneous.Such as, Chinese patent literature discloses a kind of forging hammer
[application number: 201520088191.1], including frame and hammer stem, described frame is arranged
There is chute；Described hammer stem is slidably connected in chute；Described frame and the intersection of chute
It is fixed with anchorage bar；Axle sleeve free to rotate it is arranged with on described anchorage bar；Described axle
Set position is corresponding with the notch position of chute horizontal direction.
Above-mentioned scheme cooperates to realize the purpose that hammer stem guides by hammer stem and axle sleeve,
But the one side being only oriented towards outside chute due to hammer stem contacts with axle sleeve, its residue and chute pair
The side answered does not has guide frame, and hammer stem still there will be left and right skew during using
Problem, although can by hammer stem is directly contacted with chute overcome left and right skew ask
Topic, but hammer stem necessarily causes frictional force between two kinds to increase after directly contacting with chute, shadow
Ring the decrease speed of hammer stem and impulsive force, and such scheme still also exist mold easily from
The problem departed from forging hammer.
