Abstract
The utility model discloses a kind of air hammer lever fairlead, including guiding body, it is characterized in that the inside of described guiding body is hammer stem sliding eye, the inwall of described hammer stem sliding eye is provided with one layer of bit copper layer, the outer ring of described guiding body is provided with circular mounting seat, one end face of circular mounting seat is provided with multiple anti-rocking recess, is provided with O-ring or rubber strip in anti-rocking recess, and described guiding body is provided with multiple Oil Guide lubrication holes.Air hammer lever fairlead of the present utility model, because the contact surface with hammer stem adopts bit copper layer, substantially increases the service life of fairlead, decreases because of fairlead abrasion or ftractures the maintenance cost leading to and time, improves the whole work efficiency of pneumatic hammer.
Description
Technical field
This utility model is related to forging equipment field and in particular to a kind of air hammer lever fairlead.
Background technology
Pneumatic hammer is a kind of forging equipment, and it is pushed the work forward piston using compressed air, drives tup to hit metal works,
Reach the purpose of molding.Because metalwork intensity is big, hardness is high, and molding difficulty is big, so pneumatic hammer will hit through high-frequency
Beat and just enable, the operating frequency which results in air hammer lever is very high, every point of hammer stem frequency on general pneumatic hammer equipment
Clock works 80 times about, and each order of classes or grades at school moves up and down and will reach more than 3,000 time, and during pneumatic hammer work, vibration is big, often leads
Cause hammer stem fairlead cracking, thus causing pneumatic hammer cannot work and stop production, the overall work efficiency of impact equipment.
Content of the invention
For solving the defect in above-mentioned technology, this utility model provides a kind of air hammer lever fairlead, including fairlead
It is characterised in that the inside of described guiding body is hammer stem sliding eye, the inwall of described hammer stem sliding eye is provided with one layer of bit copper to body
Layer, the outer ring of described guiding body is provided with circular mounting seat, and an end face of circular mounting seat is provided with multiple anti-rocking recess, prevents
It is provided with O-ring or rubber strip, described guiding body is provided with multiple Oil Guide lubrication holes in shake groove.
In order to reach not only economic but also practical purpose, the thickness of described bit copper layer is 2-6mm.
In order to reach preferably shockproof purpose, described anti-rocking recess is evenly arranged on the end face of circular mounting seat, shockproof
Groove is semicircle or inverted trapezoidal.
Beneficial effect：Air hammer lever fairlead of the present utility model, because the contact surface with hammer stem adopts bit copper layer, greatly
Improve greatly the service life of fairlead, decrease because of fairlead abrasion or ftracture the maintenance cost leading to and time, improve
The whole work efficiency of pneumatic hammer.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is I portion partial enlarged drawing.
In figure：1st, guiding body 2, hammer stem sliding eye 3, bit copper layer 4, circular mounting seat 5, anti-rocking recess 6,
Oil Guide lubrication hole.
Specific embodiment
A kind of air hammer lever fairlead, including guiding body 1 it is characterised in that the inside of described guiding body 1 is hammer
Bar sliding eye 2, the inwall of described hammer stem sliding eye 2 is provided with one layer of bit copper layer 3, and the outer ring of described guiding body 1 is provided with circular peace
Dress seat 4, an end face of circular mounting seat 4 is provided with multiple anti-rocking recess 5, is provided with O-ring or rubber strip in anti-rocking recess 5,
Described guiding body 1 is provided with multiple Oil Guide lubrication holes 6；In order to reach not only economic but also practical purpose, the thickness of described bit copper layer 3
Spend for 2-6mm；In order to reach preferably shockproof purpose, described anti-rocking recess 5 is evenly arranged on the end face of circular mounting seat 4,
