Abstract
The utility model discloses a novel air cylinder head cover structure. According to the novel air cylinder head cover structure, a case cover is formed by stretching a vibration-reducing composite board through a die, and the vibration-reducing composite board is formed by bonding two steel plates and a layer of damping glue in the middle. Due to the fact that a cylinder head cover formed by the vibration-reducing composite board is adopted, the novel air cylinder head cover structure has the advantage in noise reduction performance, and the noise generated by the work of internal parts of an engine can be greatly reduced. An effective groove is formed between the peripheral outer ring and an annular inner protection strip, a sealing ring is embedded in the groove, and therefore the sealing effect of the air cylinder head cover can be achieved, the material can be saved, the cost can be lowered, and the comprehensive market competitive power of products can be improved.
Description
Technical field
The utility model discloses a kind of Novel cylinder cover cover structure, by International Patent Classification (IPC) (IPC), divides and belongs to engine housing technical field, especially relates to the valve mechanism cover that a kind of double-layer plate is produced.
Background technique
Valve mechanism cover is the case covering on engine cylinder-body, and its Main Function is as follows: 1, prevent that foreign matter from entering motor; 2, prevent inner lubricating oil leakage; 3, mist of oil separates; 4, crankcase pressure regulates; 5, the noise that isolation structure transmits; 6, as the erection support of other parts.Traditional valve mechanism cover is typically chosen in aluminum casting, ironcasting, common individual layer steel plateelement on material, its shortcoming is that cost effect high and vibration and noise reducing is very undesirable, directly have influence on service behaviour and the efficiency of motor, cost improves and then also has influence on the confidence of client to product.
For vibration and noise reducing, valve mechanism cover adopts inside and outside shell structure at present, and its technique is by general steel plate, to make shell and inner casing respectively, is then welded, and complex process and cost are higher.China document CN200520034054.6 discloses a kind of noise-reducing cylinder head cover for engine, this cylinder head cover is the overlapping stamping forming cylinder head cover of double-layer plate, but the double-layer plate in document is to be superposeed by common plate, the cylinder head cover of its moulding still has room for improvement aspect vibration and noise reducing.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of Novel cylinder cover cover structure rational in infrastructure, adopts that to have the composite sheet of noise-and-vibration-reduction function one-body molded.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of Novel cylinder cover cover structure, is by die drawn, to be shaped to clamshell by damping clad plate, and described damping clad plate is to be bonded by two-layered steel plates and middle one deck damping glue.
Further, described clamshell opening side is attachment face, and in the periphery outer ring of this attachment face and ring-type, guard strip forms the groove that seal ring is installed, and interior guard strip is by the annular plate of steel plate forming and is welded on the step surface of clamshell inner side.
Further, between the front and rear wall of described clamshell, be provided with at least one hog frame, in clamshell, be provided with shell separator, under it, engine support is housed, the clamshell bottom of shell separator one side wears pipe joint, this pipe joint side communicates with connecting tube, and pipe joint bottom outlet is provided with flange and is fixed in valve mechanism cover.
The utility model adopts the cylinder head cover of damping clad plate moulding, it is advantageous that anti-acoustic capability, the noise sending when it can reduce engine interior part time job significantly, particularly, for the valve mechanism cover of casting, can embody cost advantage and performance advantage more.

Fig. 3 is A-A sectional view in Fig. 2.
Fig. 4 is C-C sectional view in Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Embodiment: refer to Fig. 1 to Fig. 4, a kind of Novel cylinder cover cover structure, is to be shaped to clamshell 1 by damping clad plate by die drawn, described damping clad plate is to be bonded by two-layered steel plates and middle one deck damping glue.Clamshell 1 opening side is attachment face, and the periphery outer ring 11 of this attachment face forms with the interior guard strip 12 of ring-type the groove that seal rings are installed, and interior guard strip 12 is by the annular plate of steel plate forming and is welded on the step surface of clamshell inner side.Between the front and rear wall of clamshell 1, form three hog frames 101,102,103, in clamshell, be provided with shell separator 13, engine support 14 is housed under it, the clamshell bottom of shell separator one side wears pipe joint 15, this pipe joint side communicates with connecting tube 16 and extends to valve mechanism cover and forms ozzle 160 outward, and pipe joint bottom outlet is provided with flange 17 and is fixed in valve mechanism cover.
A preparation process for valve mechanism cover, comprises damping clad plate blanking, stretching, shaping, deburring, hole flanging, finally welds guard strip 12 in ring-type, and the drawing gap of mould is 1.8mm.In stretching operation, master cylinder pressure: 15-20MPa, end cylinder pressure: 8-12MPa; Master cylinder pressure in plastic operation: 15-20MPa.The electrode pressure of guard strip in welding ring-type: 0.4MPa, heat: 32 ± 5KA, pressing time: 20 ± 3T, weld interval: 15 ± 3T.
The utility model valve mechanism cover, its material is the vibration damping double-layer plate that adopts species abundance in Baosteel in Shanghai, and the trade mark is BVDS-1, and base material is DC06.This material, for material in the past, it is advantageous that anti-acoustic capability, the noise sending when it can reduce engine interior part time job significantly.Particularly, for the valve mechanism cover of casting, more can embody cost advantage and performance advantage.And the record that did not in the past have double-layer vibration damping plate to make for valve mechanism cover.
Structurally, the attachment face of valve mechanism cover has a groove that seal ring is housed to the utility model, is all the processing method that adopts milling in the processing technology of this groove in cast member in the past, wastes time and energy, and increases cost, waste material.And the process program that this case adopts is the novel process of the inner welding of outer end moulding: shell (case) is one-body molded, what inner ring adopted is to utilize sheet forming to go out effective a kind of fillet plate, then inside and outside point is welded into one, just structurally interior outer member cooperatively interacts, form an effective groove, seal ring is inlayed into, well played the effect of sealing, such structure can meet the seal action of valve mechanism cover, can save again material, reduce costs, improve the market synthesized competitiveness of product.
Above record, only, for utilizing the embodiment of this origination techniques content, modification, variation that any those skilled in the art use this creation to do, all belong to the scope of the claims that this creation is advocated, and be not limited to those disclosed embodiments.
