Abstract
The present invention discloses a kind of pneumatic hammer Piston reform method, it is characterised in that its processing step is, 1. top cover and piston only are assembled together first, 2. then being drilled in the seam crossing of top cover and piston only, 3. by drilling and tapping, 4. screw is screwed in seam screw hole.Realize that piston top cover is fitted close with piston only and forms an entirety.Compared with prior art, the present invention can solve the problem that the loosened screw caused by the high intensity action of pneumatic hammer, reduce the fault rate of equipment, the stability of lifting means；Reduce artificial repair rate；Pneumatic hammer hitting dynamics is more stable, continual and steady offer power.
Description
Technical field
The present invention relates to a kind of pneumatic hammer piston, especially a kind of pneumatic hammer Piston reform method.Suitable for abrasion-proof steel ball
Loose tooling forging pneumatic hammer Piston reform.
Background technology
The pneumatic hammer that production line uses at present has two cylinders, and one is compression cylinder, and another is working cylinder.Entering
When row forges operation, compression cylinder compresses air, is sent into working cylinder by distributing valve, promotes piston to be done up and down together with tup
Hammer action is moved.The upper top cover of the piston of cylinder is split type with piston only at present, and upper top cover uses with piston only
Split type fixation.This piston in working condition by larger pressure when easily there is loosened screw, fracture and upper top
Lid gas leakage etc., cause pneumatic hammer hitting dynamics insufficient, influence to produce；So fault rate is higher, the time between overhauls(TBO) is frequent, average 15 days
Need maintenance once, influence production efficiency.Therefore, study it is a kind of by existing Piston reform into the relatively low pneumatic hammer piston of fault rate
Remodeling method, it is the current technical issues that need to address.
The content of the invention
The technical problems to be solved by the invention be to provide it is a kind of by existing Piston reform into the relatively low pneumatic hammer of fault rate
The method that piston changes.
The present invention solve its technical problem technical scheme be：
Pneumatic hammer Piston reform method, its processing step are that 1. top cover and piston only are assembled together first, are 2. then existed
The seam crossing of top cover and piston only drills, and 3. by drilling and tapping, 4. screws on screw in seam screw hole.Realize piston top cover
It is fitted close with piston only and forms an entirety.Solution Split piston rivet loosens caused by frequent use, gas leakage
Phenomenon.
Compared with prior art, the present invention can solve the problem that the loosened screw caused by the high intensity action of pneumatic hammer, reduce
The fault rate of equipment, the stability of lifting means；Reduce artificial repair rate；Pneumatic hammer hitting dynamics is more stable, holds
Stable offer power is provided.

Embodiment
Pneumatic hammer Piston reform method, it is characterised in that its processing step is 1. first to assemble top cover and piston only
Together, 2. and then in the seam crossing of top cover and piston only drill, 3. by drilling and tapping, 4. screw on spiral shell in seam screw hole
Silk.Realize that piston top cover is fitted close with piston only and forms an entirety.
