Abstract
The invention discloses a durable check valve assembly on an air hammer. The check valve assembly comprises a check valve bush, a check valve rod assembly, a spring seat and a spring. The check valve assembly is characterized in that the check valve rod assembly comprises an air inlet/outlet valve block, a valve rod reinforcing seat and a valve rod; and the diameter ratio of the valve rod to the valve rod reinforcing seat to the air inlet/outlet valve block is 4:8:11-12. According to the check valve assembly on the air hammer, through reasonable setting of the external diameter ratio of the air inlet/outlet valve block, the valve rod reinforcing seat and the valve rod, the service life of the check valve is greatly prolonged; and in addition, through a conical spring shaft sleeve, the stability of reciprocating motion of the valve rod is improved, and the service life of the valve rod is further prolonged.
Description
Technical field
The present invention relates to forging equipment field is and in particular to a kind of non-return valve assembly on pneumatic hammer.
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, which results in the check-valves on pneumatic hammer equipment and enter that frequency of giving vent to anger is very high, stopping on general pneumatic hammer equipment
Return valve and enter frequency of giving vent to anger work per minute 80 times about, each order of classes or grades at school will reach 3500 times about.The non-return of high-frequency operation
Valve rod easily causes fatigue fracture, thus causing pneumatic hammer cannot work and stop production, the overall work efficiency of impact equipment.
Content of the invention
For solving deficiency of the prior art, it is an object of the invention to provide stopping on a kind of long-lived pneumatic hammer
Return valve assembly：
Including non-return valve pocket, check-valve lever assembly, spring base, spring it is characterised in that described check-valve lever assembly includes passing in and out
Air valve plate, valve rod reinforced seat, valve rod, the diameter of described valve rod and valve rod reinforced seat and air valve piece is than for 4:8:11-12.
Described spring base one end is volute spring axle sleeve, and spring base center is stem through-hole, described volute spring axle sleeve
External conicity is：1:15-25.
The material of described valve rod is 35CrMo, modifier treatment.
Beneficial effect：Non-return valve assembly on the pneumatic hammer of the present invention passes through air valve piece, valve rod reinforced seat and valve rod
The reasonable disposition of external diameter ratio substantially prolongs the service life of check-valves, and improves the past of valve rod by volute spring axle sleeve
The stability of multiple motion, further increases the use time of valve rod.
Brief description
Fig. 1 is the structural representation of the present invention.
In figure：1st, non-return valve pocket 2, check-valve lever assembly 3, spring base 4, spring 21, air valve piece 22, valve rod add
Strong seat 23, valve rod 31, volute spring axle sleeve 32, stem through-hole.
Specific embodiment
A kind of non-return valve assembly on pneumatic hammer：Including non-return valve pocket 1, check-valve lever assembly 2, spring base 3, spring 4, its
It is characterised by that described check-valve lever assembly 2 includes air valve piece 21, valve rod reinforced seat 22, valve rod 23, described valve rod 23 and valve
The diameter of bar reinforced seat 22 and air valve piece 21 is than for 4:8:11-12, described spring base 3 one end is volute spring axle sleeve 31,
Spring base 3 center is stem through-hole 32, and the external conicity of described volute spring axle sleeve 31 is：1:15-25, the material of described valve rod 23
Expect for 35CrMo, modifier treatment.
