Abstract
A screw washer comprises a washer body, wherein the outer edge of the washer body is bent downwards to form a folded edge, and a concave platform is formed by taking a through hole of the washer body as a center; the back of the joint of the hem and the concave station of the gasket is raised upwards to form a convex ring, and a groove is formed at the joint of the inner side of the hem and the concave station. The utility model discloses a set up the concave station on ordinary level and smooth gasket, make the screw packing ring avoid the long-pending powder region of enamel, avoided the direct contact of the long-pending powder department of in-process screw and packing ring and enamel of beating the screw to solved because of the two directly exert pressure the long-pending powder department of enamel and produced the porcelain explosion problem. The design not only reduces the reject ratio of the enamel product, but also avoids other associated adverse consequences caused by repeated reworking due to porcelain explosion, greatly improves the self quality of the product and saves the production cost.
Description
Technical field
The utility model relates to a kind of screw packing ring that is applied to enamel (Enamel) product, belongs to the improvement technology of gasket construction.
Background technique
After the enamel processing was being done on the surface of sheet metal part, the phenomenon (see figure 1) that the enamel powder is piled up can appear in the screwing through hole periphery of reservation.Because the enamel layer on sheet metal part surface itself has the character of glass, so receiving the phenomenon that just can occur explosion when certain external force is pushed when enamel layer; And explosion takes place owing to directly contact with screw in enamel powder accumulation place more easily in practical operation.Explosion place of enamel layer not only can influence the outward appearance of product, and panel beating surface can be exposed in the air because of the protection that loses enamel layer, occurs the situation of getting rusty then, thereby has a strong impact on the quality and the life-span of product.At present; Many products have added flat gaskets in the middle of the enamel layer of screw and sheet metal part; Reducing screw directly to the friction and the extruding at enamel accumulated powder place, but packing ring itself still can contact with enamel accumulated powder place, so such measures can't fundamentally solve the burst porcelain problem.Therefore, be necessary to do further improvement.
The model utility content
The purpose of the utility model aims to provide a kind of screw packing ring that can improve enamel product quality, reduction enamel spare burst porcelain reject ratio and need not increase production process, to overcome the deficiency of existing technology.
A kind of screw packing ring by the design of this purpose comprises packing ring, and its structure characteristic is that the downward bending of the outer rim of said packing ring forms flanging, and is formed centrally concave station in the through hole of packing ring being.
The back of the flanging of said packing ring and concave station joint upwards protuberance forms bulge loop, forms groove in the inboard and the concave station joint of flanging.
Said packing ring buckles on the enamel layer of sheet metal part, and the concave station button of packing ring covers on the top at enamel accumulated powder place, and does not contact with enamel accumulated powder place.
Shu the hemming is curved or shaped, folding the side or lower end of the enamel layer.
Screw passes through hole from the concave station back, and packing ring and sheet metal part and other part are fixed.
The utility model is through being provided with concave station on common smooth packing ring; Make the packing ring of screw avoid enamel accumulated powder zone; Avoided direct contact of screw and packing ring and enamel accumulated powder place in beating the process of screw, produced the burst porcelain problem thereby solved directly enamel accumulated powder place to be exerted pressure because of the two.The design has not only reduced the enamel product reject ratio, has also avoided other related adverse consequences of repeatedly doing over again and being brought of causing because of the burst porcelain phenomenon, and has improved the sole mass of product greatly, has practiced thrift cost of production.
Description of drawings
Fig. 1 is the prior art constructions schematic representation.
Fig. 2 is the utility model one example structure schematic representation.
Among the figure: 1 is packing ring, and 1.1 is flanging, and 1.2 is groove, and 1.3 is concave station, and 2 is enamel layer, and 2.1 is enamel accumulated powder place, and 3 is sheet metal part.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Referring to Fig. 2, a kind of screw packing ring comprises packing ring 1, and the downward bending of the outer rim of packing ring forms arc flanging 1.1, and is formed centrally concave station 1.3 in the through hole of packing ring 1 being.Flanging 1.1 upwards swells with the back of the joint of concave station 1.3 and forms bulge loop, and forms groove 1.2 in the inboard of flanging 1.1 and the joint of concave station 1.3.The setting of bulge loop has not only increased the intensity of packing ring 1, in addition better positioning screwn.
Before playing screw, on the enamel layer 2 of sheet metal part 3, the inboard of arc flanging 1.1 contacts with enamel layer 2 with packing ring 1 buckle closure, and makes concave station 1.3 detain the top that covers on enamel accumulated powder place 2.1, and concave station 1.3 does not contact with enamel accumulated powder place 2.1.Then, screw passes through hole from the back of concave station 1.3, and enamel sheet metal part 3 is connected with other part.Because the concave station 1.3 of screw packing ring 1 has been avoided the enamel accumulated powder zone on the enamel layer 2, avoided the direct extruding at screw and 1 pair of enamel accumulated powder of packing ring place 2.1, thereby solved the problem that burst porcelain takes place because of pressurized enamel layer 2.
