Abstract
The utility model relates to a rammed rear cover for a diesel engine, belonging to the part of the diesel engine. The utility model uses the steel plate whose thickness is 1.5 mm as the material, and the rammed rear cover for a diesel engine is a rammed component which is provided with a periphery flange and reinforcing ribs among eight fastening bolt holes, namely, circular arc convex ribs and x shaped reinforcing ribs. The circular arc shaped convex ribs of the reinforcing ribs are connected to compose a ring belt whose periphery is sealed, and the ring belt is contacted with the rear plane of the cylinder body of the diesel engine in line way, which prevents the pressure oil in cylinder body leaking. The flange and the reinforcing ribs enhance the rigidity of large area, avoiding large plane being radiated, reducing the vibration, and decreasing the noise. The utility model has the advantages of light weight and shapely configuration. An oil dipstick hole is inlaid with a powder metallurgical liner which is smooth, clean, lubricating, rust-proof and abrasion-proof, and thus, the oil dipstick is easy to be sealed and measured.
Description
The utility model relates to a kind of diesel engine punching press bonnet, belongs to the parts of diesel engine.
Known diesel engine bonnet is a Cast Iron Products, and manufacturing process is loaded down with trivial details, needs casting bonnet blank, also will carry out machining, the manufacture cost height, and cast iron bonnet outward appearance is coarse, and heavy.
The purpose of this utility model is that existing cast iron bonnet is improved, avoid the above-mentioned deficiency of prior art and provide that a kind of manufacturing process is simple, cost is low, in light weight and outward appearance is beautiful, have flange, stiffening rib and stud with the diesel engine punching press bonnet in metallurgical powder lining dipstick hole.
Task of the present utility model is finished by following technical measures.
The utility model is a rectangle, and four jiaos is circular arc, has flange 1 around it is peripheral, has increased the integral rigidity of bonnet, and the long side face of bonnet is a monocline face wedge shape, is provided with stiffening rib 2 between eight fastening screw keyholes 3---the circular arc convex tendon.Stiffening rib 2 is connected to form seal band, becomes line to contact with the diesel engine cylinder block back plane, prevents the leakage of cylinder interior pressure machine oil.The cover plate ramp surface is provided with the X-shaped stiffening rib, protrudes 2 millimeters of ramp surfaces, has strengthened the rigidity on big plane and has avoided the big plane of radiation, reduces vibration, reduces noise.Recessed dipstick hole 4, cover plate middle part studs with powder metallurgy lining, can reduce cost, weight reduction, and lining is bright and clean, and lubricating condition is good, is difficult for getting rusty, and is wear-resisting, is easy to dipstick sealing and frequent extracting and inserting.It is material that the utility model adopts 1.5 millimeters steel plates, and its circumferential perimeter flange is high 4 millimeters, has increased the integral rigidity of bonnet.
The utility model compared with prior art has following advantage:
1, the utility model adopts stamped technology to make, and technology is simple, does not have machining, and whole parts do not have burr, and the surface is complete bright and clean, and the outward appearance svelteness reduces manufacture cost, weight reduction, and its weight has only 1/3 weight of ironcasting.
2, flange of the present utility model and stiffening rib at interval large-area radiation surface, and can strengthen rigidity, reduce vibration, reduce noise, make it in light weight, handsome in appearance.
3, dipstick of the present utility model hole studs with powder metallurgy lining, have bright and clean, lubricate, wear-resisting, be easy to dipstick sealing and the frequent advantage of extracting and inserting.
The explanation of accompanying drawing drawing:
Fig. 1 is a front view of the present utility model.
Fig. 2 is a side view of the present utility model.
Fig. 3 is the A-A sectional view among Fig. 1.
The 1-flange, 2-stiffening rib, 3-bolt hole, 4-dipstick hole, 5-powder metallurgy lining, 6-X shape stiffening rib.
Embodiment of the present utility model is identical with technological scheme.
Claims (2)
1, a kind of diesel engine punching press bonnet, the parts that belong to diesel engine, it is characterized in that rammed bonnet is a rectangle, its four jiaos is circular arc, and its circumferential perimeter has flange 1, and the long side face of cover plate is a monocline face wedge shape, be provided with stiffening rib 2-circular arc convex tendon between eight fastening screw keyholes 3, stiffening rib is connected to form endless belt, and the cover plate ramp surface is provided with the X-shaped stiffening rib, and cover plate middle part studs with powder metallurgy lining 5 in the recessed dipstick hole 4.
