Abstract
The invention discloses a gas valve conduit manufacturing process and particularly relates to manufacturing of diesel engine accessories. The gas valve conduit manufacturing process includes: firstly, processing casts under condition of guaranteeing the casts to meet processing requirements; after processing, performing magnaflux inspection on the surfaces of workpieces, and demagnetizing; after finishing processing of the workpieces, cleaning and blowing the workpieces, placing the workpieces into a baking box, keeping the temperature at about 200 DEG C for 2 hours, taking the workpieces out and immediately soaking the workpieces into lubricating oil for 4 hours, taking out the workpieces for drying and wrapping by oil paper finally. The inner walls of gas valve conduits manufactured by the gas valve conduit manufacturing process are incomparably smooth. After gas valves are sleeved into the conduits, friction among the gas valves and the inner walls of the conduits are reduced to the greatest extent, and loss of the workpieces and cost are reduced.
Description
Technical field
The present invention relates to a kind of manufacturing of diesel engine part, be specifically related to a kind of combustion gas door conduit manufacturing process.
Background technique
Combustion gas door conduit is accessory indispensable on the diesel engine, by the produced combustion gas door of tratitional technology conduit, its pipe inner wall smoothness is inadequate, after the combustion gas door pocket enters conduit, the frictional force of combustion gas door and pipe inner wall is very large, the oil that rocking-arm driving mechanism in the time of often can only moving reciprocatingly in conduit by the combustion gas door on the cylinder cap is transmitted is splashed to pipe inner wall, lubricant oil enters conduit and just can reduce friction, in case forget lubricating oil filling, the friction of pipe inner wall and combustion gas door will increase greatly, when the combustion gas door moves, will accelerate its loss in conduit.
Summary of the invention
Goal of the invention: the present invention provides a kind of and can make the smooth combustion gas door conduit manufacturing process of combustion gas door pipe inner wall in order to solve the deficiencies in the prior art.
Technological scheme: a kind of combustion gas door conduit manufacturing process, described combustion gas door conduit manufacturing process comprises following technological process:
(A) processing foundry goods;
(B) after the Mechanical processing of casting moulding, do magnetic particle flaw detection on the operative workpiece surface, and demagnetization;
(C) after the process finishing, workpiece cleaning is blown off, put into baking oven, 190 ℃-210 ℃ of constant temperature kept 2 hours, put into immediately lubricant oil after the taking-up, soaked 4 hours, dried after the taking-up, packed tightly with oilpaper at last.
As preferably, described technological process (A) processing foundry goods, used foundry goods should guarantee smooth surface without burr, the inwall grain structure is fine and close, loose bubble, shrinkage cavity, crackle must not occur.
Beneficial effect: a kind of combustion gas door conduit manufacturing process of the present invention, by the produced combustion gas door of its technological process conduit, pipe inner wall is smooth incomparable, after the combustion gas door pocket enters conduit, farthest reduced the friction of combustion gas door and pipe inner wall, reduce the loss of workpiece, reduced cost.
