Abstract
The utility model relates to a metal accumulation layer gasket connecting structure for an engine. The metal accumulation layer gasket connecting structure comprises a gasket body. The gasket body comprises a first thin metal sheet and a second thin metal sheet. The first thin metal sheet and the second thin metal sheet are connected to form an integral structure through a riveting mold. The gasket body is formed by two layers or several layers of thin metal sheets. The thin metal sheets are made of stainless steel or low carbon steel sheets. The metal accumulation layer gasket connecting structure has the advantages of being novel in structure, good in manufacturability, simple in processing and easy to detect, and being remarkably improved in reliability. In addition, in terms of manufacturing processes, manufacturing procedures are reduced, labor intensity of workers is lowered, production cost is decreased, problems of crack and drop of rivets are solved, sealing performance is improved, and practicability is high.
Description
Technical field
The utility model relates to a kind of engine metal laminate pad syndeton.
Background technology
At present people use mostly is greatly cylinder mouth hatch frame metal laminate pad, and the connection between each laminate of pad is mostly adopted rivet or welded this two kinds of connected modes.The equipment investment cost of welding connecting mode is high, efficient is low, energy consumption is high, particularly when having rubber coating pad or the pad more than three layers to produce, often occurs welding or the phenomenon of not prison welding; Rivet connection operation is many, labour intensity is large, and connection rivet is prone to crackle, obscission, and the not tight phenomenon of gasket seal all easily appears in these two kinds of connected modes in addition, affects result of use, makes troubles to people.
The utility model content
The purpose of this utility model is to provide a kind of engine with metal laminate pad syndeton, to overcome at present existing pad bindiny mechanism above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of engine comprises shim body with metal laminate pad syndeton, and described shim body comprises sheet metal one and sheet metal two, and described sheet metal one connects as one structure with sheet metal two by riveting die set; Described riveting die set comprises die ontology, and described die ontology comprises punch, die, stripping attachment and alignment pin.
Further, described shim body is comprised of two-layer or some layers of sheet metal.
Preferably, described sheet metal is stainless steel or low carbon steel plate.
The beneficial effects of the utility model are: metal laminate gasket construction of the present utility model is novel, good manufacturability, and processing is simple, be easy to detect, and reliability significantly improves; On manufacture craft, this product has not only reduced production process in addition, has reduced workman's labour intensity, has reduced production cost, and the phenomenon that has effectively solved the rivet cracking, come off, and has strengthened sealing, and practicality is very strong.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is the cutaway view that the described a kind of engine of the utility model embodiment is used metal laminate pad syndeton;

In figure:
1, sheet metal one; 2, sheet metal two; 3, punch; 4, die; 5, shim body.
The specific embodiment
As shown in Fig. 1-2, the described a kind of engine of the utility model embodiment links structure with the metal laminate pad and connects, comprise shim body 5, described shim body 5 comprises sheet metal 1 and sheet metal 22, and described sheet metal 1 connects as one structure with sheet metal 22 by riveting die set; Described shim body 5 is comprised of two-layer or some layers of sheet metal; Described sheet metal is stainless steel or low carbon steel plate.
As shown in Figure 3-4, when this pad of processing, at first riveting die set is placed on hydraulic press, then each laminate is accurately located on riveting die set, utilize hydraulic press pressure, make punch 3 that each laminate material is pressed into die 4 simultaneously, this moment, the plastic deformation of depressed position material production, formed the riveting point, thereby sheet metal 1 and sheet metal 2 are connected as one, its special feature is to connect and need not rivet, utilizes sheet metal 1 and the stressed plastic deformation of sheet metal 2 to connect as one structure; Rivet in addition Position Design position of pressurized not after pad installation, place, the corresponding engine oil of pad water hole, the pad outer rim is the position of pressurized not, riveted joint place number can be according to the pad size design, as two places or more than two places, the riveted joint shape can be circle or rectangle etc., and practicality is very strong.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation on its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection domain of the present utility model.
Claims (3)
