Abstract
The invention relates to a method of press mounting a copper sheath of an oil atomizer of a cylinder head, which includes the following steps: (1) processing the cylinder head and the copper sheath; (2) mounting the copper sheath in the cylinder head, thereby the bottom plane of the copper sheath presses the bottom surface of the cylinder head; (3) conducting plastic deformation on the copper sheath by using a steel ball, thereby forming a subassembly of the cylinder head and the copper sheath which can satisfy the requirement of sealing. By using the steel ball to press the inner cone surface of the copper sheath, plastic deformation takes place on the copper sheath and the copper sheath is embedded in a lower ring groove of the cylinder head, thereby constituting a sealing surface with the cylinder head to realize the sealing of cooling water. Compared with a traditional mode which employs a method of outward expansion of a rotating core shaft, the invention has the advantages of less equipment investment cost, simple and effective process, low energy consumption and flexible deformation on the premise of satisfying the requirements on the product; the invention is suitable for the production of cylinder heads of diesel engines of various specifications.
Description
Technical field
The present invention relates to a kind of production technology of cylinder cover for diesel engine oil sprayer, relate in particular to a kind of cylinder cap fuel injector copper sheathing pressure-mounting method.
Background technique
Along with the enforcement of state's 2 dischargings, diesel emission to be had higher requirement, existing diesel gradually adopts four Valves Technology, to reduce the inlet and outlet resistance, strengthens the inlet and outlet flow.After adopting four Valves Technology, because cylinder head is left the installing space of oil sprayer copper sheathing for and is compressed, the mode that can't continue to adopt swivel nut to compress copper sheathing is carried out the sealing of cooling water, the seal form of therefore existing copper sheathing has been improved to the structural type of upper end seal ring, lower end embedding annular groove, it is relatively large promptly to go up end spaces, adopts the O RunddichtringO to seal; Following end spaces is less relatively and operating temperature is high, can't adopt the O RunddichtringO, adopts copper sheathing is carried out plastic deformation processing, makes it embed the cylinder head annular groove, makes copper sheathing lower plane, following cylndrical surface constitute sealing surface, finishes the sealing to cooling water.
Traditional cylinder cap fuel injector copper sheathing pressure-mounting method is to adopt the rotation mandrel that copper sheathing is carried out companding, and Fig. 5 is cylinder head copper sheathing load module figure.Copper sheathing 2 upper ends form sealing by O RunddichtringO 1 and cylinder head 3, prevent that cooling water from entering oil sprayer from the upper end; By copper sheathing 2 being carried out plastic deformation processing, make its lower end embed 3 times annular grooves of cylinder head, form sealing with copper sheathing 2 lower end surfaces to cooling water.The traditional approach that adopts the rotation mandrel to extend out can reach product requirement, and equipment investment is big, the modification type is dumb, high shortcoming consumes energy but exist.
Summary of the invention
The purpose of this invention is to provide a kind of cylinder cap fuel injector copper sheathing pressure-mounting method, effectively solve prior art and adopt the rotation mandrel that copper sheathing is carried out companding to have that equipment investment is big, the conversion type is dumb, high shortcoming consumes energy.
To achieve these goals, the invention provides a kind of cylinder cap fuel injector copper sheathing pressure-mounting method, comprise step:
Step 1, processing cylinder head and copper sheathing;
Wherein said step 1 is specially:
Step 11, on cylinder head, process closure gasket groove;
Step 12, process inner conical surface in the copper sheathing lower end.
Wherein said step 2 is specially:
The O RunddichtringO is installed in step 21, the cylinder head;
The copper sheathing of packing in step 22, the cylinder head;
Step 23, the pressure head of packing in the copper sheathing rear end;
Step 24, exert pressure, make the copper sheathing lower plane overlay the cylinder head bottom surface to pressure head.
Wherein said step 3 is specially:
Step 31, in pressure head, put into steel ball and depression bar successively;
Step 32, exert pressure to depression bar, steel ball pushes copper sheathing lower end inner conical surface, makes it produce plastic deformation and embeds the cylinder head ring gasket groove;
Step 33, steel ball pass copper sheathing and drop from the cylinder head another side, are met the cylinder head copper sheathing assembly parts of seal request.
The present invention proposes a kind of copper sheathing pressure-mounting new method of the copper sheathing lower end being carried out plastic deformation, earlier process inner conical surface in the copper sheathing lower end, adopt the inner conical surface of steel ball companding copper sheathing lower end, make it produce the closure gasket groove that plastic deformation embeds cylinder head, copper sheathing lower plane, following cylndrical surface and cylinder head constitute sealing surface jointly, finish the sealing to cooling water.Compare with the method that traditional approach adopts the rotation mandrel to extend out, the present invention is reaching under the product requirement prerequisite, has characteristics such as equipment investment is little, technology is simple effectively, power consumption is low, modification is flexible, is applicable to the production of the cylinder cover for diesel engine of all size.
Below by drawings and Examples, technological scheme of the present invention is described in further detail.
