Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] A processing method for an aluminum alloy bottle cap 1, comprising:

[0032] I longitudinal rib processing steps

[0033] Wherein, the longitudinal rib portion processing step uses a longitudinal rib portion processing device, and the longitudinal rib portion processing device includes: an extruding head 2 and a bottle cap installation cylinder 3, the extruding head 2 is roughly cylindrical, and its cylindrical There are longitudinal protruding strips 22 and longitudinal grooves 21 on the side. The number of the longitudinal protruding strips 22 and the longitudinal grooves 21 is four, and they are arranged at intervals. The radially outer sides of the longitudinal grooves 21 are all cylindrical surfaces. A part of the radially outer surface of the longitudinal protruding strip 22 is a part of the conical surface, and in any section perpendicular to the longi...

Abstract

Disclosed is a method for processing an aluminum alloy cap. The method includes a vertical rib processing step and an inner thread processing step. The vertical rib processing step includes extruding an extruding head into a cap blank slowly from the opening of the cap blank, accordingly extruding a concave part and a convex part on the inner side of the cylindrical side wall of the cap blank, and acquiring the cap blank with the concave part and the convex part. The inner thread processing step includes assembling an executing component on the inner side of the cylindrical side wall of the cap blank with the concave part and the convex part, starting a hydraulic lifting device and a rotary motor, forming a thread on the convex part accordingly, and obtaining the aluminum alloy cap.

Description

technical field [0001] The invention relates to a processing method for a bottle cap, in particular to a processing method for an aluminum alloy bottle cap. Background technique [0002] Bottle caps are widely used in the prior art. Corresponding to different applications and needs, there are also different requirements for the firmness of the bottle cap and the joint method of the bottle cap and the bottle body. In the sealing application of some important containers, materials with high firmness and strength are often required, such as metal materials or aluminum alloy materials. [0003] There are various methods of processing bottle caps. However, at present, various processing methods for bottle caps are actually specially used for plastic bottle caps. This kind of bottle caps is easy to process and can achieve a certain sealing or sealing effect, but it is difficult to meet the requirements for firmness in specific fields. . [0004] For the processing of metal bot...
