Abstract
The invention discloses an engine hydraulic steering pump production process. The production process comprises the following steps of selecting martensite materials to be submerged and in a calcium carbonate and aluminum hydroxide mixed solution and dried; performing reduction reaction in the reducing atmosphere; adding beryllium bronze to be mixed with the mixed solution to be poured into a die-casting die to be subjected to pressure casting to obtain blanks; performing carburization processing to form a carburization layer; quenching the carburized blanks to be taken out and cooled. By means of the production process, a good vibration force dispersion effect can be provided, the engine steering pump service life can be prolonged, materials are saved, the use rate is improved, the equipment service lift is increased, and the steering pump service life can be prolonged.
Description
Technical field
The invention belongs to Machining Technology field, particularly relate to a kind of manufacture craft of engine hydraulic steering pump.
Background technology
Engine is the important motivity source of a lot of equipment, and the vibrations of the vibrations suffered by normal conditions engine hydraulic steering pump and self generation are larger, and long-time use can cause damage to self.Affect the life-span of engine and the safe operation of equipment itself.
Summary of the invention
(1) technical problem that will solve
The technical problem to be solved in the present invention is: the manufacture craft that the object of the present invention is to provide a kind of engine hydraulic steering pump.
(2) technical scheme
In order to solve the problems of the technologies described above, the invention provides a kind of manufacture craft of engine hydraulic steering pump, comprising the following steps:
First choose martensitic material, martensitic material carbon containing 2-4%, manganese 0.2-0.7%, aluminium 0.02-0.06%, surplus is iron; Martensitic material soaks 2-5 minute in the mixed solution of calcium carbonate and aluminium hydroxide, and taking-up is dried; Then in reducing atmosphere, reduction reaction is carried out; Add the beryllium-bronze of its quality 20% again, jointly mix, pour in the middle of die casting after mixing and carry out die casting, obtain the blank of engine steering pump; Blank working surface carries out Carburization Treatment, forms carburized layer 2-6 sub-micron; Then put into bright quenching stove to quench, hardening heat 100-258 degree Celsius, time 25-39 minute; Cooling after taking out.
Preferably, described martensitic material carbon containing 5%, manganese 0.6%, aluminium 0.05%, surplus is iron.
(3) beneficial effect
Technique scheme tool has the following advantages: according to technical scheme of the present invention, better can play the effect of disperse vibration power, can extend the life-span of engine steering pump, saves material, increases operation rate.The service life of raising equipment.
Detailed description of the invention
Below in conjunction with embodiment, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
A manufacture craft for engine hydraulic steering pump, comprises the following steps:
First choose martensitic material, martensitic material carbon containing 2-4%, manganese 0.2-0.7%, aluminium 0.02-0.06%, surplus is iron; Martensitic material soaks 2-5 minute in the mixed solution of calcium carbonate and aluminium hydroxide, and taking-up is dried; Then in reducing atmosphere, reduction reaction is carried out; Add the beryllium-bronze of its quality 20% again, jointly mix, pour in the middle of die casting after mixing and carry out die casting, obtain the blank of engine steering pump; Blank working surface carries out Carburization Treatment, forms carburized layer 2-6 sub-micron; Then put into bright quenching stove to quench, hardening heat 100-258 degree Celsius, time 25-39 minute; Cooling after taking out.
Preferably, described martensitic material carbon containing 5%, manganese 0.6%, aluminium 0.05%, surplus is iron.
According to technical scheme of the present invention, better can play the effect of disperse vibration power, the life-span of engine steering pump can be extended, save material, increase operation rate.The service life of raising equipment.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and replacement, these improve and replace and also should be considered as protection scope of the present invention.
