Description
Technical field
The present invention relates to a kind of automatic production line that engine valve is carried out salt bath nitrocarburizing.
Background technology
Engine valve need carry out salt bath nitrocarburizing (tufftride) to valve in manufacturing processed, the technical process of salt bath nitrocarburizing is: feed → deoil (one) → (the two) → hot water that deoils cleaning (one) → hot water cleans (two) → preheating → nitrogenize → cooling () → hot water and cleans (three) → oven dry (one) → oxidation → cooling (two) → hot water cleaning (four) → hot water cleaning (five) → oven dry (two) → discharging.Wherein, the operation of deoiling is carried out in the case that deoils, and the hot water matting is carried out in cleaning case; Preheating procedure carries out in preheating oven, and the nitrogenize operation is carried out in nitriding furnace, and refrigerating work procedure carries out in cooling tank; Baking operation carries out in stoving oven, and oxidation operation carries out in oxidized still.
At present in the valve manufacturing; Valve is carried out the used equipment of salt bath nitrocarburizing; Like the above-mentioned case that deoils, cleaning case, preheating oven, nitriding furnace, oxidized still, stoving oven and cooling tank all is that the mode that adopts the well formula to install is installed in subsurface; Manual work is carried out hanging the transfer product with the manual control electricblock behind the material loading, thisly carries out product by manual work and hangs the salt bath nitrocarburizing of transfer and have following defective:
1, each station time is controlled by manual work, and randomness is stronger, there is a strong possibility cause quality product not controlled, consistence is relatively poor.As: poor cleaning can influence the product appearance quality, and warm up time, deficiency also can have bigger influence to product bar portion's linearity and nitride layer, and whether the length of tufftride time then directly has influence on nitride layer depth, hardness of product etc. qualified.
2, in the salt bath nitrocarburizing process, lean on manual pick to hang the transfer product with the manual control electricblock, not only expend time in, and working strength of workers is big, production efficiency is very low.
3, environmental pollution is big.Cleaning case, the case that deoils all can produce a large amount of water vapors in the salt bath nitrocarburizing process, nitriding furnace and oxidized still can produce a large amount of waste gas, flue dust, and production environment and operator, equipment are all had disadvantageous effect.
Summary of the invention
The purpose of this invention is to provide a kind of valve salt bath nitrocarburizing automatic production line, in the valve salt bath nitrocarburizing, each operation except that stocking process can be carried out on this automatic production line automatically.
Valve salt bath nitrocarburizing automatic production line according to the invention; Comprise the driving frame, be installed in the Crane Rail of driving on the frame, be supported on the driving on the Crane Rail, the PLC automatic control equipment of control driving action; And be positioned under the Crane Rail, and follow oxidized still, nitriding furnace, first, second cooling tank, first, second, third, fourth, the 5th cleaning case, preheating oven, stoving oven and first, second case that deoils that the Car Track direction is arranged.
Said oxidized still and first case that deoils lays respectively at the two ends of driving frame, is aligned in sequence with second cooling tank, cleaning politics, economics, organization, and ideology tank-washer, the 5th cleaning case, stoving oven, the 3rd cleaning case, first cooling tank, nitriding furnace, preheating oven, second cleaning case, first cleaning case and second case that deoils from oxidized still to the case that deoils.
This arrangement mode can adapt with the technical process of valve salt bath nitrocarburizing, in valve salt bath nitrocarburizing process, can make the stroke of driving the shortest.
Be provided with the dust flue with its internal communication on oxidized still and nitriding furnace top, the total pipe coupling of dust flue and dust discharge is equipped with vacuum fan in the dust discharge house steward; Be provided with the vapor pipe with its internal communication at first, second cooling tank, first, second, third, fourth, the 5th cleaning case, stoving oven and first, second upper box part that deoils, vapor pipe is connected with exhaust-gas receiver, and vacuum fan is installed in exhaust-gas receiver.
Processing requirement according to the valve salt bath nitrocarburizing is programmed; The PLC automatic control equipment is controlled driving automatically; Make driving walk motion in that Crane Rail is up by the technical process of valve salt bath nitrocarburizing; The bin that is hung with valve is moved to next station from a last station, on each station, stop, and carry out actions such as discharging frame, a bin by the time of setting.Waste gas, dust that first, second total smoke exhaust pipe produces oxidized still, nitriding furnace, and the water vapour that cooling tank, cleaning case, stoving oven and the case that deoils produce is discharged outside the work-yard.
Valve salt bath nitrocarburizing automatic production line according to the invention; Oxidized still, nitriding furnace, cooling tank, cleaning case, preheating oven, stoving oven and the case that deoils are arranged in driving down; Utilize driving to come discharging frame, play bin and shift bin; And driving is controlled based on the processing requirement of valve salt bath nitrocarburizing by the PLC automatic control equipment; Can move according to the processing requirement of valve salt bath nitrocarburizing, thereby make valve in salt bath nitrocarburizing, each operation except that stocking process can be carried out on this automatic production line automatically.
Because the discharging frame of driving, a bin, transfer bin and the residence time on each station have been realized automatic control; Do not need manual work to carry out manual operation; Thereby greatly reduced working strength of workers, and guaranteed the stable of consistency of product and quality product.
Owing in production line, be provided with the exhaust device that comprises dust flue, dust discharge house steward, vapor pipe, exhaust-gas receiver and vacuum fan; Pollutents such as its waste gas that can valve be produced in salt bath nitrocarburizing, dust, water vapour are discharged outside the work-yard, thereby make the valve salt bath nitrocarburizing have good working environment.
