Abstract
The present invention relates to a method for manufacturing an easily openable cap-shaped bottle cover, which comprises the following procedures: firstly, a material plate is punched, stretched and flanged to make an inner ring of a pull tab; secondly, the pull tab and the outer edge of a connecting sheet are obtruded, or alternatively, a material plate for the pull tab and the connecting sheet and a material plate for the bottle cover are simultaneously obtruded; thirdly, the material plate for the pull tab and the connecting sheet is folded on the material plate for the bottle cover; finally, the easily openable cap-shaped bottle cover is made by using a mould for making the bottle cover. A product produced in the method of the present invention can ensure that the center of the inner ring of the pull tab of the product coincides with the center of a circle of the bottle cover and the connecting sheet tightly overlaps the bottle cover, the product completely conforms to technical requirements, and the qualified rate of the product is obviously improved.
Description
Technical field
The present invention relates to a kind of method of making bottle cap, particularly relate to a kind of method of making easy unlatching Crown shape bottle cap.
Technical background
Existing easy unlatching Crown shape bottle cap has a common bottle cap, on its outer rim a connecting piece is arranged, and the other end of this connecting strap connects a draw ring, and this draw ring discount is on bottle cap.At present, usually produce this easy unlatching Crown shape bottle cap with the thick tin-plate of 0.23-0.28mm, the shape of on flitch, drawing materials earlier, i.e. a great circle and a roundlet, there is strip piece connecting in the middle of them, again this part material that draws is punched down, then circular portion is processed into bottle cap and draw ring respectively.The small circular flitch is made the inner ring of draw ring through punching, stretching and flange, promptly makes draw ring; Big circular flitch is made bottle cap and is used, and bottle cap is made through punching press with corresponding mould.After making draw ring and bottle cap respectively draw ring is folded on the bottle cap.The product of producing in this way, the center of its draw ring inner ring and the center of circle of bottle cap are difficult to coincide together, and both cooperate badly, and connecting strap and bottle cap are also not closely folding.Therefore be difficult to reach technical requirements, the qualification rate of product is not high.
Summary of the invention
The purpose of this invention is to provide a kind of method of making easy unlatching Crown shape bottle cap, it can overcome the above-mentioned deficiency of prior art.
A kind of method of making easy unlatching Crown shape bottle cap, earlier flitch punching, stretching and flange are made the inner ring of draw ring, again draw ring with the connecting strap outer rim is gone out or draw ring connecting strap flitch and bottle cap flitch are gone out simultaneously, then draw ring connecting strap flitch is folded on the bottle cap flitch, makes easy unlatching Crown shape bottle cap with the mould of system bottle cap at last.
The product of producing with method of the present invention can guarantee that the center of its draw ring inner ring overlaps with the center of circle of bottle cap, and connecting strap and bottle cap are closely overlapping, meet technical requirements fully, and the qualification rate of product obviously improves.
Specific embodiments
Embodiment 1 gets the tin-plate flitch that thickness is 0.25mm, flitch punching, stretching and flange are made the draw ring inner ring, and punching hole diameter is 17mm, and the diameter behind stretching, the flange is 19mm, draw ring and connecting strap outer rim are gone out, this moment, the other end of connecting strap still was connected with remaining bottle cap flitch again.The diameter of this draw ring outer rim is 31mm, and the width that connects sheet stock is 6mm, and length is 3.6mm.Then draw ring of making and connecting strap flitch are folded on the bottle cap flitch, make easy unlatching Crown shape bottle cap with the mould of system bottle cap at last.This moment, connecting strap was made into incorporate profile of tooth with the burst of bottle cap.According to Crown shape bottle cap (GB/T13521-92) request of national standard, dashing of existing system cover mold tool expects that a mouthful diameter is 38mm; For this reason, during with this bottle cap of mould system, the bottle cap material board diameter is 38mm.
Embodiment 2 present embodiments are made the inner ring of draw ring similarly to Example 1 earlier, again draw ring connecting strap flitch and bottle cap flitch are gone out simultaneously, then draw ring connecting strap flitch is folded on the bottle cap flitch, make easy unlatching Crown shape bottle cap with the mould of system bottle cap at last, the size of its product each several part and effect and embodiment 1 are identical.
The above-mentioned folding method of draw ring and connecting strap flitch and bottle cap flitch that makes adopts method of frustrating or pushing method, its fold line is all at the intersection of connecting strap and bottle cap flitch, consider that flitch has certain thickness, for the center that makes the draw ring inner ring and the center of circle of bottle cap accurately overlap, the length sum of the radius of draw ring flitch and connecting strap flitch will surpass the radius of bottle cap flitch, and its difference is about half of flitch thickness.By the method for frustrating, earlier flitch is bent at the fold line place, and then it is tied or rolling overlaps on the bottle cap flitch draw ring and connecting strap with frustrating plate; By the pushing method, adopt two templates, standing away between them forms the slit of a broad, and flitch is put thereon, makes its fold line be positioned at the center of this segment distance, pushes downwards with hard sheet pressing element again.Flitch is subjected to the pushing effect folding from its fold line, and the flitch after folding enters in the above-mentioned slit, and draw ring and bottle cap flitch have just folded accurately after flattening.
