The present invention provides a kind of processing method of hollow piston rod, and it comprises the following steps：A, blanking, the bar of corresponding material is selected；B, forge, according to the size rough forging part of piston rod；C, pincers worker, both ends centre bore line is drawn, center hole is bored at both ends respectively, and punch beats a wire hole at center；D, make annealing treatment, reduce the hardness of piston rod；E, 0.2 04mm surpluses are stayed in turning roughing, turning roughing；F, wire cutting, the through hole among wire cutting；G, it is heat-treated, quenches and be tempered guarantee hardness 62 65HRC；H, turning semifinishing, turning semifinishing leave 0.04 0.06mm surpluses；I, refine, grinding machine fine grinding ensures 0.3~0.6um of surface roughness Ra to size requirement；J, mirror-finish.The processing method of hollow piston rod of the present invention, process is simple, it is rationally proper to arrange, and improves the fatigue resistance and wearability of piston rod, reduces processing cost.
Description
Technical field
The present invention relates to a kind of processing method of piston rod, more particularly to a kind of processing method of hollow piston rod.
Background technology
Piston rod is the connection member of supporting piston acting, and major applications are in oil cylinder, cylinder moving execution unit
The moving component that one motion is frequent, technical requirements are high.Solid more of the piston rod of prior art, hollow is less, tradition
Hollow piston rod processing method it is complex, due to its processing method arrange the unreasonable fatigue resistance for causing piston rod and
Wearability greatly reduces.
The content of the invention
【1】Technical problems to be solved
The technical problem to be solved in the present invention is to provide a kind of process it is simple, arrange it is rationally proper, it is possible to increase piston rod
Fatigue resistance and wearability hollow piston rod processing method.
【2】The technical scheme solved the problems, such as
The present invention provides a kind of processing method of hollow piston rod, and it comprises the following steps：
A, blanking, the bar of corresponding material is selected；
B, forge, according to the size rough forging part of piston rod；
C, pincers worker, both ends centre bore line is drawn, center hole is bored at both ends respectively, and punch beats a wire hole at center.
D, make annealing treatment, reduce the hardness of piston rod.
E, 0.2-04mm surpluses are stayed in turning roughing, turning roughing；
F, wire cutting, the through hole among wire cutting；
G, it is heat-treated, quenches and be tempered guarantee hardness 62-65HRC；
H, turning semifinishing, turning semifinishing leave 0.04-0.06mm surpluses；
I, refine, grinding machine fine grinding ensures 0.3~0.6um of surface roughness Ra to size requirement；
J, mirror-finish.
Further, in step d, the annealing temperature is 150-250 DEG C, and soaking time is 1 hour.
Further, in step g, the hardening heat is 850-900 DEG C, and temperature is 100-130 DEG C.
【3】Beneficial effect
The processing method of hollow piston rod of the present invention, process is simple, it is rationally proper to arrange, and improves the antifatigue strong of piston rod
Degree and wearability, reduce processing cost.
Embodiment
The embodiment of the present invention is described in detail below.
The present invention provides a kind of processing method of hollow piston rod, and it comprises the following steps：

C, pincers worker, both ends centre bore line is drawn, center hole is bored at both ends respectively, and punch beats a wire hole at center.
D, make annealing treatment, reduce the hardness of piston rod.
E, 0.2-04mm surpluses are stayed in turning roughing, turning roughing；
F, wire cutting, the through hole among wire cutting；
G, it is heat-treated, quenches and be tempered guarantee hardness 62-65HRC；
H, turning semifinishing, turning semifinishing leave 0.04-0.06mm surpluses；
I, refine, grinding machine fine grinding ensures 0.3~0.6um of surface roughness Ra to size requirement；
J, mirror-finish；
In order to improve the effect of annealing, in the present embodiment, in step d, annealing temperature is 150-250 DEG C, soaking time
For 1 hour；
In order to improve the fatigue resistance of piston rod and wearability, in the present embodiment, in step g, hardening heat is
850-900 DEG C, temperature is 100-130 DEG C.
The processing method of hollow piston rod of the present invention, process is simple, it is rationally proper to arrange, and improves the antifatigue strong of piston rod
Degree and wearability, reduce processing cost.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvements and modifications can also be made, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
