Process by the way of double-deck or multilayer material Compound hot extrusion or heat inlay rear extrusion molding.
Preferably, described blind end can process pore-forming according to demand.
Preferably, described hydraulic cylinder part is not less than the 12% good structural steel of plasticity as blank using elongation percentage.
A kind of processing method of the hollow hydraulic cylinder part of one end closing, hydraulic cylinder part is tied for the hollow that one end is closed
Structure, blind end is non-solder form, adds local using one hot piercing and forges integrally formed mode and process, the tool of part processing
Body step is：
Step a, austenitation heat treatment：Elongation percentage is selected to be not less than the 12% good structural steel of plasticity as blank, plus
Heat, to the state exceeding 10-30 DEG C of austenitizing temperature, selects temperature retention time according to blank specification；
Step b, hot piercing：Carry out hot piercing with plug, and do not penetrate, form the hollow structure of one end closing；Wherein, wear
The plug in hole is preheated to more than 400 DEG C, can slow down the cooling velocity of blank in perforation procedure；
Step c, heating：According to the temperature after blank perforation it is necessary to enforcement reheating in order to follow-up forging plus
Work；
Step d, local are forged：Profile as needed, processes each of end or centre by the way of rapid forge
Plant shape；
Step e, heat treatment：Normalizing and modifier treatment；
Step f, machining：Inner bore of part outer circular shape according to demand and precision, carry out machining or local is squeezed
Molded.
Compared with prior art, the hydraulic cylinder part that the present invention processes, can improve material ratio of briquetting, improving hydraulic cylinder can
Diversity by property, saving total energy consumption, raising Element Design is supported.And, this processing method, hydraulic cylinder can be made to produce real
Output that is now reliable, stable, not limited by batch size.Due to using integrally formed technology, achievable groove, hole, spiral shell
The flexible design of the profile relative position such as line control cylinder gross weight.
