Abstract

The utility model discloses a structure of a metal tank cover, which pertains to the technical field of product packaging and packaging manufacture. The structure of the metal tank cover is characterized in that the metal tank cover is formed by two metal plates (a modeling plate and a connecting structure plate) through forming of shearing, punching, and combining of hemming; the metal plate at the upper layer is the modeling plate and can be punched into various forms or patterns according to needs; the metal plate at the lower layer is the connecting structure plate; and a bulge of approximately 1 centimeter is punched downwards in the middle of the connecting structure plate according to the shape and the size of the inner diameter of a tank opening, thus forming a connecting structure which can be plugged into the tank opening. The modeling plate at the upper later and the connecting structure plate at the lower layer have consistent diameter and shape after punching and forming, and the edges of the two metal plates are combined by mechanical hemming to form the complete cover.

Description

The structure of one cover metal can lid

Technical field: relating to metallic material packing technique field, exactly is a kind of processing technology that metallic material (as tin-plate, aluminium flake) packing is made.

Background technology: present mental package cover on the market is generally the punching press of unitary piece of metal sheet and makes, and shape is based on cylindrical shape, square, and form, function are comparatively single, can't realize the innovation of form.

Summary of the invention: the utility model is Package tin lid with traditional ridge shape that will provide a cover to be made by sheetmetal, combine through shearing, punching press, flanging process by moulding sheet and structure connecting strap, take into account the metal can lid that function combines with form.

The technical scheme that the utility model is taked is: a kind of structure of metal can lid, the outer of round can lid moulding sheet is circular, middle smooth, annular protrusion such as ridge on every side, the cylinder that connection structure sheet outer is circular, centre portion protrudes downwards, both are connected in the outer of moulding sheet with the connection structure sheet.

A kind of structure of metal can lid, the outer squarely of side's cover moulding sheet, middle smooth, square projection such as ridge on every side, the square cylinder that connection structure sheet outer squarely, centre portion protrude downwards, both are connected in the outer of moulding sheet with the connection structure sheet.

A kind of structure of metal can lid, outer squarely, the centre of the sub-moulding sheet of pinnacle square tank cover raises up as the pinnacle ridge, the square cylinder that connection structure sheet outer squarely, centre portion protrude downwards, both are connected in the outer of moulding sheet with the connection structure sheet.

Moulding sheet and connection structure sheet are through shearing, punching press, the metal can lid that mental package processing technologys such as crimping combine, the moulding sheet strikes out traditional ridge shape through machine up, the connection structure sheet is cut into the outer profile same with the moulding sheet through mechanical shear, it is identical with jar mouthful internal diameter that centre portion stamps out downwards, the projection that height is about one centimetre, form the stopper that seals that to fill in jar mouth, the outer of moulding sheet and connection structure sheet is by the fixing metal can lid that forms of flanging process, top moulding sheet and the following connection structure sheet outline size after the difference punch forming, shape should be consistent, with the edge of two sheetmetals by mechanical crimp in conjunction with forming complete lid, because the outer profile of whole metal can lid is bigger than jar diameter of mouth, when the downward bossing of connection structure sheet is filled in the jar mouth, outer profile greater than the jar mouth can be fixed on lid on the metal can, plays fixing, the leak free effect.

The specific embodiment:

Now the utility model is described in further detail in conjunction with the accompanying drawings, and the utility model is that a kind of metal can lid with ridge shape that is combined through shearing, punching press, flanging process by moulding sheet and structure connecting strap will be provided.Smooth in the middle of the moulding sheet strikes out, protruding as pentroof on every side; Structure connecting strap process mechanical shear is cut into the shape of hollow, and interior being stamped into horizontal direction along part is the short tubular that an angle of 90 degrees stretches out vertically downward, becomes and can body bonded assembly structure.The moulding sheet is connected with the flanging process of structure connecting strap by the outer.

1. round can lid: comprise by moulding sheet (Fig. 3) and connection structure sheet (Fig. 4) and forming, it is characterized in that: moulding sheet (Fig. 3) is circular through mechanical shearing, and is smooth in the middle of striking out, projection is as the shape of ridge (1) on every side again; Connection structure sheet (Fig. 4) is circular through mechanical shearing, and centre portion stamps out the projection (2) about a centimetre downwards, forms the stopper that seals that can fill in jar mouth.The outer of moulding sheet and connection structure sheet (3) is connected to form round can lid (Fig. 5) by flanging process.The round can lid is filled in jar mouthful (Fig. 6) with connection structure (2) and is gone up the complete mental package jar of formation.
