Technical field
The present invention relates to easy-open bottle lid production field, and in particular to easy-open bottle lid is from rivet forming method and mould.
Background technology
In the prior art, the rivet forming method on easy-open bottle lid is as follows：The first step is first stamped and formed out coronal bulb, the
Negative drawing forms rivet to two steps again.Using the above method, phenomenon that the rivet list face of shaping is easily burst apart with depainting.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of high easy-open bottle lid of Forming Quality from rivet
Forming method and mould.
To achieve the above object, the present invention uses following technical scheme：
Easy-open bottle lid divides three steps from rivet forming method, the forming method,
The first step：Coronal bulb is stamped and formed out on material strip；
Second step：Continue to be stamped and formed out semi-spherical portion on the basis of coronal bulb is stated；
3rd step：Columned rivet is formed to above-mentioned semi-spherical portion negative drawing.
The basal diameter in the coronal bulb is identical with the diameter of semi-spherical portion.
The basal diameter in the coronal bulb and the diameter of semi-spherical portion are more than 2.5 times of final molding rivet diameter.
The height of the rivet is more than the diameter of rivet.
A kind of easy-open bottle lid is set at equal intervals from rivet mould, including upper bolster and die shoe, the mould
There are three stations, the first station is the shape bulb station that has a crack for champion, and to rush semi-spherical portion station, second station is formed second station for reverse drawing
Rivet station；
First station includes the first punch-pin being located on upper bolster and the first cavity plate being correspondingly arranged on die shoe, and first is convex
The bottom of mould has spherical crown shape convex portion, has the cavity being adapted with spherical crown shape convex portion on the first cavity plate；
The second station includes the second punch-pin being located on upper bolster and the second cavity plate being correspondingly arranged on die shoe, and second is convex
The bottom of mould has half-spherical convexes, has the cavity being adapted with half-spherical convexes on the second cavity plate；
The 3rd station includes the 3rd punch-pin being located on die shoe and the 3rd cavity plate being correspondingly arranged on upper bolster, and the 3rd is convex
The top of mould has cylindric convex portion, has the cavity being adapted with cylindric convex portion on the 3rd cavity plate.
The basal diameter of the spherical crown shape convex portion is identical with the diameter of half-spherical convexes.
The basal diameter of the spherical crown shape convex portion and the diameter of half-spherical convexes be 2.5 times of cylindric convex portion diameter with
On.
The height of the cylindric convex portion is more than the diameter of cylindric convex portion.
The present invention uses above technical scheme, and the forming process of rivet is divided into three steps, first reversely stretched in two steps
Semi-spherical portion is re-formed to be formed behind coronal bulb, finally pulls back to form rivet again, to ensure the height of rivet of stretching, aforesaid way
The rivet quality of shaping is high, surface will not be caused to burst apart, depainting phenomena such as.
Brief description of the drawings
The present invention is described in further details below in conjunction with the drawings and specific embodiments：
Fig. 1 is the schematic diagram of the present invention.
Embodiment
As shown in figure 1, easy-open bottle lid of the present invention divides three steps from rivet forming method, the forming method,
The first step：Coronal bulb 10 is stamped and formed out on material strip 9；
Second step：Continue to be stamped and formed out semi-spherical portion 11 on the basis of coronal bulb 10 is stated；
3rd step：Columned rivet 12 is formed to the above-mentioned negative drawing of semi-spherical portion 11.
The basal diameter in the coronal bulb 10 is identical with the diameter of semi-spherical portion 11, and the basal diameter in coronal bulb 10
Diameter with semi-spherical portion 11 is more than 2.5 times of the diameter of final molding rivet 12.
The height of rivet 12 is more than the diameter of rivet 12 after final molding.
A kind of easy-open bottle lid from rivet mould, including upper bolster 1 and die shoe 2, the mould at equal intervals
Provided with three stations, the first station is the shape bulb station that has a crack for champion, and for second station to rush semi-spherical portion station, second station is reverse drawing shape
Into rivet station；
First station includes the first punch-pin 3 being located on upper bolster 1 and the first cavity plate 4 being correspondingly arranged on die shoe 2, the
The bottom of one punch-pin 3 has spherical crown shape convex portion 31, has the cavity being adapted with spherical crown shape convex portion 31 on the first cavity plate 4；
The second station includes the second punch-pin 5 being located on upper bolster 1 and the second cavity plate 6 being correspondingly arranged on die shoe 2, the
The bottom of two punch-pin 5 has half-spherical convexes 51, has the cavity being adapted with half-spherical convexes 51 on the second cavity plate 6；
