Description
Technical field
The present invention relates to technical field of valve manufacturing, more particularly, to a kind of valve handle processing method.
Background technique
Handwheel is chronically exposed in air and is oxidized and gets rusty valve handle in order to prevent after production, needs in hand
Wheel surface varnishes with lacquer.In the prior art, it includes two kinds that the japanning processing method of handwheel is main, and one kind is existed using paintbrush
Handwheel square hole is avoided on handwheel and is uniformly coated with paint, and this processing method is time-consuming and laborious, and painting quality is not also high, is unfavorable for giving birth to
It produces, another way is that handwheel is directly placed in painting case the japanning by the way of dip-coating, but in this way, in handwheel square hole
A large amount of paint will be remained, when causing to install valve rod, valve rod is difficult to fix across perforation with handwheel, therefore in following process
When, it is also necessary to paint removal operation is carried out to handwheel square hole, increases workload.
Summary of the invention
The present invention for overcome the deficiencies in the prior art, provides a kind of valve handle processing method.
To achieve the goals above, the invention adopts the following technical scheme: a kind of valve handle processing method, including it is following
Step:
A, Operational preparation: prepare including the material preparation for producing valve handle casting and manufacturing machine equipment and related grinding tool；
B, it smelts: carrying out charge composition and select suitable melting mode, reasonable smelting temperature and time are set, during which to valve
The material composition content of door cast member is controlled；
C, it pours casting: the cast member material of smelting being poured into grinding tool type is intracavitary to be carried out pouring moulding；
D, cooling: handwheel molding after moulding is cooled down；
E, ball blast: Shot Blasting is carried out to handwheel using lesser steel ball, strengthens handwheel surface quality and deburring；
F, japanning: japanning and drying are carried out to handwheel using painting equipment, obtain handwheel finished product；
Wherein, the painting equipment in the step f includes handwheel feeding device, clamping device, transmission device, painting installation, baking
Equipment for drying, the cleaning plant cleared up for clamping device, the clamping device include that equidistant arrangement is more on transmission device
The rotating seat of a equidistant arrangement, the grip slipper for being fixed at rotating seat upper surface, annular array are set to two groups of gas on grip slipper
Bar, first group of triangle grip block being fixed on wherein one group of gas bar, second group of triangle being fixed on another group of gas bar
Grip block, the recessing groove on first group of triangle grip block, the clamping device are integrally inserted into handwheel square hole, wherein one group
Gas bar drives first group of triangle grip block to move outward, and another group of gas bar drives second group of outside sidesway of triangle grip block again
It is dynamic, it completes to clamp handwheel；The present invention pushes first group of triangle grip block and second group of grip block by two groups of gas bars respectively, makes
By fixed handwheel inner hole, paint is avoided to enter in square hole, and clamping device is avoided to fill for a long time using abrasion, handwheel and clamping
Gap increase is set, paint enters in square hole, while by being equipped with multiple grip slippers, solving and keeping away under the premise of improving handwheel japanning
Exempt from handwheel square hole to become smaller after japanning problem；By the painting installation, quality after improving japanning, japanning efficiency also has certain
It improves；By drying unit, the handwheel after japanning is dried, drying rate is fast, and the handwheel is processed caused by avoiding because of drying
The bottleneck of process and influence whole work efficiency；By cleaning plant, paint is carried out to clamping device and is handled, avoided for a long time
Operation, paint is increasingly thicker and influences subsequent clamping device insertion handwheel square hole.
Material composition in the step b is mainly the refining steel ingot for using 90-95%, and stokehold first adds in furnace bottom in ingredient
Enter the FeSi of molten steel weight 1.5%-2%, be finally incorporated Ni element, a certain amount of nitrogen is added, reduces containing for harmful element P, S
Amount；Make in furnace substance total amount reach in it is online；The content of harmful element P, S are reduced, and is controlled by reducing chromium/nickel equivalent ratio P
Ferritic content is made, ferritic content in the entire tissue of reduction is reached, to avoid or reduce ferrite embrittlement and geneva
Body is abnormal；Next avoids S content that valve is made to pull the S in casting and forms HS in conjunction with H, can cause the stress corrosion of metal material
Cracking.
It is described be added nitrogen content be 0.06-0.2%, harmful element P, S content control respectively P < 0.03%, S <
0.016%；The chromium/nickel equivalent ratio P controls P≤0.9 again, and ferrite content is controlled 5.0% hereinafter, increasing and pulls casting
Each convenient function of part.
