Abstract
The utility model relates to a blocked shaping die for an oil nozzle blank of a high-pressure common rail system. The blocked shaping die comprises an upper die core, an upper die sleeve, an upper punch, a lower die core, a lower die sleeve and a lower punch, wherein the upper die core and the lower die core are arranged oppositely one above the other; the die cavity of the upper die core corresponds to the die cavity of the lower die core one above the other; the die cavities of the upper die core and the lower die core correspond to each other one above the other; the die cavities of the upper die core and the lower die core are combined to construct an entire oil nozzle blank die cavity; the upper die sleeve surrounds the outer side of the upper die core; the lower die sleeve surrounds the outer side of the lower die core; the upper punch vertically passes through the upper die core from top to bottom, and extends into the die cavity of the upper die core; and the lower punch vertically passes through the lower die core from bottom to top, and extends into the die cavity of the lower die core. The utility model provides a blocked shaping die for an oil nozzle blank of a high-pressure common rail system which is suitable for a blocked forging forming process.
Description
Technical field
The utility model relates to the inaccessible shaping dies of a kind of high pressure co-rail system atomizer blank.
Background technology
Fuel injector is most critical and the most complicated parts in the joint-track type fuel system, it is made up of magnetic valve, atomizer, injection valve etc., its effect is the control signal of sending according to ECU, by the opening and closing of control magnetic valve, the fuel oil in the high pressure oil rail is sprayed into the combustion chamber of diesel engine with injection timing, distributive value and the fuel injection rate of the best.Atomizer inside is processed with fuel feed hole, spill port, control valve opening etc., because the installing space of engine is limited, it is very big that the diameter of atomizer can not design, thereby cause the wall ratio between the inner several holes of atomizer less, wall thickness between hole and the cylindrical is also very little, and main engine plants all require to improve the expulsion pressure of diesel oil for improving the exhaust emissions performance of engine, improve its atomization, thereby reduce discharging.The expulsion pressure of diesel oil generally all reaches 120-200MPa at present, high expulsion pressure like this, requirement to the fuel injector blank is very high, comprise material, interior tissue, forging flow lines continuously, requirements such as blemish, skin decarburization layer depth, it is continuous to reach forging flow lines as need, the middle part does not produce the effect of overlap, and just necessary employing closed-die extrusion forging technology technology so just needs design a suitable high pressure co-rail system atomizer blank obturation shaping mould bases and the mould that is applicable to this mould bases.
The utility model content
The purpose of this utility model is to overcome the defective that prior art exists, and a kind of inaccessible shaping dies of high pressure co-rail system atomizer blank that is applicable to closed-die extrusion forging technology technology is provided.
The technical scheme that its technical problem that solves the utility model adopts is: the inaccessible shaping dies of a kind of high pressure co-rail system atomizer blank, comprise upper mold core, Upper Die-sleeve, upper punch, lower mold core, lower die-sleeve and low punch, described upper mold core and lower mold core are oppositely arranged up and down, and the die cavity of upper mold core is corresponding up and down with the die cavity of lower mold core, on described, the die cavity of lower mold core merges the back and constitutes whole atomizer blank cavity, described Upper Die-sleeve is enclosed in the upper mold core outside, lower die-sleeve is enclosed in the lower mold core outside, described upper punch vertically passes the die cavity that upper mold core stretches into upper mold core from top to bottom, and described low punch vertically passes the die cavity that lower mold core stretches into lower mold core from bottom to up.
Described whole atomizer blank cavity is the cylindricality die cavity that top has projection, and the contact-making surface of described upper mold core and lower mold core is die joint, and this die joint is arranged on the upper surface of described projection.
The beneficial effects of the utility model: the utility model has solved the defective that exists in the background technology, design the inaccessible shaping dies of a high pressure co-rail system atomizer blank, low punch and upper punch while extrusion billet during forging and molding, the blank non-trimming produced after blank was shaped, inner forging flow lines is continuous, dense internal organization, the mechanical strength height of blank.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of preferred embodiment of the present utility model.
Wherein: 1, upper mold core; 2, Upper Die-sleeve; 3, upper punch; 4, lower mold core; 5, lower die-sleeve; 6, low punch; 7, whole atomizer blank cavity; 7-1, projection; 8, die joint.
The specific embodiment
The inaccessible shaping dies of a kind of high pressure co-rail system atomizer blank as shown in Figure 1, comprise upper mold core 1, Upper Die-sleeve 2, upper punch 3, lower mold core 4, lower die-sleeve 5 and low punch 6, described upper mold core 1 is oppositely arranged up and down with lower mold core 4, and the die cavity of upper mold core is corresponding up and down with the die cavity of lower mold core, on described, lower mold core 1,4 die cavity merges the back and constitutes whole atomizer blank cavity 7, described Upper Die-sleeve 2 is enclosed in upper mold core 1 outside, lower die-sleeve 5 is enclosed in lower mold core 4 outsides, described upper punch 3 vertically passes the die cavity that upper mold core 1 stretches into upper mold core 1 from top to bottom, and described low punch 6 vertically passes the die cavity that lower mold core 4 stretches into lower mold core 4 from bottom to up.Described whole atomizer blank cavity 7 has the cylindricality die cavity of projection 7-1 for top, and described upper mold core 1 is die joint 8 with the contact-making surface of lower mold core 4, and this die joint 8 is arranged on the upper surface of described projection 7-1.
Should be appreciated that specific embodiment described above only is used for explaining the utility model, and be not used in restriction the utility model.The apparent variation of being extended out by spirit of the present utility model or change still are among the protection domain of the present utility model.
