Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples, so that those skilled in the art can be with
It more fully understands the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
In the prior art, the screw thread mouth of Aluminum Bottle is machined by rolling, the low, screw thread with production efficiency
The disadvantages of pore size low precision, is unable to satisfy the demand in market.In order to solve this problem, the present invention provides a kind of aluminium pot bottles
Mouth Thread Machining Process, the dimensional accuracy for the screw thread mouth that the production efficiency of screw thread mouth aluminium pot can be greatly improved, and processed
Height is able to satisfy the requirement of client on the market completely.
Fig. 1 is the structural schematic diagram of the aluminium pot prepared through processing technology of the invention, it can be seen from the figure that the aluminium pot packet
Include body 100, bottleneck 300 and the shoulder 200 being connected between body 100 and bottleneck 300, the mesh of processing technology of the invention
Be process screw thread on bottleneck 300.
Specifically, the processing technology the following steps are included:
Firstly, the junction of bottleneck 300 and shoulder 200 is made to form necking, then the necking is rolled, to form ring
The card slot 310 of shape.After rolling, the junction of card slot 310 and shoulder 200, card slot 310 and bottleneck 300 is each formed with arc mistake
Cross portion 311.
Then, the size before undergauge to thread forming is carried out to the bottleneck 300 of 310 top of card slot, then bottleneck 300 is carried out
It repairs and cuts so that bottleneck 300 is smooth.In a preferred embodiment, repairing to bottleneck 300 after cutting further includes being lubricated to bottleneck 300
The step of, its purpose is to screw threads easy to process.The lubrication is concretely: the position of screw thread to be processed on bottleneck 300
Spray lubricant.
Then, screw thread process is carried out to the bottleneck 300 so that bottleneck 300 forms threaded portion 320.In preferred embodiment party
In formula, after thread forming, the threaded portion 320 and the shape between the 300 diameter maximum of bottleneck of 320 lower section of threaded portion
At there is the first gradually expanding rake 321.It is furthermore preferred that the outer diameter of the 300 diameter maximum of bottleneck is greater than the screw thread
The Major Diam in portion 320.
Finally, the size of necking to crimping is carried out to the bottleneck 300 of 320 top of threaded portion, after repairing and cutting, to bottleneck 300
It carries out crimping and forms flanging part 330, to obtain the screwed aluminium pot of bottleneck 300.In a preferred embodiment, the volume
It is formed with the second gradually expanding rake 322 between the threaded portion 320 of 330 lower section of edge 330 and flanging part, this second inclination
The effect in portion 322 is easy for bottle cap and screws in the threaded portion 320.
Preferably, the outer diameter of 330 thickness of flanging part is equal to or less than the diameter of thread of the threaded portion 320, from
And it is placed on bottleneck 300 convenient for bottle cap.It is furthermore preferred that the outer diameter of 330 thickness of flanging part is equal to the threaded portion 320
Diameter of thread, at this point, can be improved the leakproofness of bottle cap when bottle cap screws.
In the present embodiment, 330 semicircular in shape of flanging part, radius 0.8mm.
The aluminium pot whorl of bottleneck processing technology of the present embodiment, can greatly improve the production efficiency of screw thread mouth aluminium pot, and one
The daily production capacity of production line can achieve 150,000 to 200,000, and the dimensional accuracy of the screw thread mouth processed is high, be able to satisfy city completely
The requirement of client on face.
Embodiment described above is only to absolutely prove preferred embodiment that is of the invention and being lifted, protection model of the invention
