Description

Engine suspension hot forging and cold punching split welding type inner core structure

Technical Field

The utility model belongs to the technical field of automobile spare and accessory parts, more specifically say, in particular to engine mounting hot forging adds cold punching components of a whole that can function independently welded type inner core structure.

Background

The engine suspension is an automobile power assembly part used for reducing and controlling the transmission of engine vibration and playing a role in supporting, and is applied to the current automobile industry.

Based on the above, the present inventors found that the following problems exist: the existing engine suspension inner cores all adopt an integral casting structure, the environmental pollution is large in a casting process, and in addition, due to the limitation of casting process defects, the defects of serious deformation, shrinkage cavities, sand holes and the like are easily generated, and the rejection rate is high.

In view of the above, the present invention provides an engine mount hot forging and cold stamping split welded core structure, which is improved based on the existing structure and defects, so as to achieve the purpose of being more practical.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides an engine mounting hot forging adds cold punching components of a whole that can function independently welding formula inner core structure to solve present engine mounting inner core and all adopt whole casting structure, casting process is great to environmental pollution, and in addition because the restriction of casting process defect, produces defects such as serious deformation, shrinkage cavity, sand hole very easily, has the problem of higher rejection rate.

The utility model discloses the purpose and the efficiency of engine mounting hot forging and cold punching components of a whole that can function independently welded type inner core structure are reached by following concrete technological means:

an engine suspension hot forging and cold punching split welding type inner core structure comprises an upper body; the bottom of the upper body is fixedly provided with a lower body through welding.

Furthermore, both sides of the bottom of the upper body are provided with an inner concave structure, and the thickness of the inner groove is equal to that of the lower body.

Furthermore, when the lower body is installed, two sides of the top of the lower body can be just embedded into the inner grooves on two sides of the bottom of the upper body, and the lower body is welded and fixed at the embedding position of the inner grooves.

Compared with the prior art, the utility model discloses following beneficial effect has:

this structure changes original whole casting technology spare into by steel hot forging shaping and carries out components of a whole that can function independently welding technology spare after steel cold punching shaping, the part surface smoothness of processing alone like this has qualitative promotion than the casting surface, and steel hot forging's product internal organization does not have casting technology product inside shrinkage cavity, internal defects such as sand hole, carry nuclear intensity higher, the environmental pollution and the high rejection rate that lead to by the casting have been reduced simultaneously, realize the dual efficiency of reduce cost and energy-concerving and environment-protective, and improved the tolerance intensity of product on the primary structure basis, product property can obtain the promotion, can satisfy the engine of higher intensity and carry the nuclear demand.

Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

In the description of the present invention, "a plurality" means two or more unless otherwise specified; the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "head", "tail", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example (b):

as shown in figures 1 to 4:

the utility model provides an engine suspension hot forging and cold punching split welding type inner core structure, which comprises an upper body 1; the lower body 2 is fixedly arranged at the bottom of the upper body 1 by welding.

Wherein, the bottom both sides of upper part of the body 1 all are provided with one concave structure, and the thickness of inner groovy equals with the thickness of lower part of the body 2, and this structure changes original whole casting technology spare into by steel hot forging shaping and carries out components of a whole that can function independently welding technology spare after the steel sheet cold punching takes shape, and the part surface smoothness of processing alone like this has the promotion of matter than the casting surface, and the product internal organization of steel hot forging does not have internal defects such as casting technology product inside shrinkage cavity, sand hole moreover.

The structure changes the original integral casting process piece into a split welding process piece after steel hot forging forming and steel plate cold punching forming, so that the surface flatness of the separately processed part is qualitatively improved compared with the casting surface, and the internal structure of the steel hot forging product does not have internal defects such as internal shrinkage holes and sand holes of the casting process product.

The specific use mode and function of the embodiment are as follows:

in the utility model, the upper body 1 and the lower body 2 are separately hot-forged and formed during the manufacturing process, then the two sides of the top of the lower body 2 are respectively butted and embedded with the inner grooves on the two sides of the bottom of the upper body 1, and then the welding and the fixing are carried out, the structure changes the original integral casting process piece into a split welding process piece after the steel hot-forging and steel plate cold-punching forming, thus the surface smoothness of the separately processed part is qualitatively improved compared with the casting surface, and the internal structure of the steel hot-forged product does not have internal defects such as internal shrinkage cavities, sand holes and the like of the casting process product, the nuclear loading strength is higher, simultaneously reduces the environmental pollution and high rejection rate caused by casting, realizes the dual effects of reducing cost and saving energy and protecting environment, and the tolerance strength of the product is improved on the basis of the original structure, the product performance is improved, and the requirement of the engine on the engine with higher strength can be met.

The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art.
