Description

Lamination assembly equipment for thin-wall high-pressure-resistant embedded ring and easy-to-open cover surface Technical Field The invention relates to the technical field of lamination of easy-to-open covers, in particular to lamination assembly equipment for a thin-wall high-pressure-resistant embedded ring and an easy-to-open cover surface. Background The easy-to-open cover, also called easy-to-open cover, is mainly made of aluminum or tin, realizes the opening function through a pre-etching score line and a riveting pull ring, is suitable for sealing containers such as iron cans, aluminum cans, composite cans and the like in the fields of food, beverage, daily chemicals and the like, and is divided into two types of round and non-round, wherein the production process covers links such as basic cover forming, pull ring combination and the like, adopts structural design and special equipment with lower interchangeability, has anti-counterfeiting characteristics, and has the performances of dampproofing, shock resistance, high temperature resistance and the like. The precise automatic process for forming the top-pop cover surface and the embedded ring (pull ring piece) by punching and riveting is characterized in that the rivet island is formed by punching the base material of the cover body, and then the embedded ring is accurately sleeved and then the rivet island material is deformed by pressing, so that the permanent fixation of the embedded ring and the top surface is realized. The method comprises the specific procedures that firstly, a rivet island is formed by directly punching and protruding an aluminum base material of a top-pop-top cover surface, then a central hole of a caulking ring (a pull ring piece) is aligned with the rivet island to be sleeved, finally, a rivet island material is pressed upwards through an upper die downwards, penetrates through the caulking ring hole, and forms a rivet column to complete riveting and fixing. Although the press-fit assembly equipment for the easy-to-open cover in the prior art can finish the basic operation, a plurality of technical defects still exist in the press-fit assembly process for the thin-wall high-pressure-resistant embedded ring and the easy-to-open cover face, and the technical defects are as follows: 1. The setting precision of the caulking ring sleeve is low, namely, when the caulking ring is sleeved on the surface of the rivet island, the caulking ring lacks a precise limiting guide structure, is roughly placed by relying on manual experience or simple tools, cannot ensure the coaxiality of a central hole of the caulking ring and the rivet island, easily causes the inclination and dislocation of the caulking ring, easily causes the problems of opening and blocking of a pull ring and uneven stress of a score line after the subsequent pressing, and seriously affects the service performance of the easy-to-open cover; 2. The prior equipment only directly presses down through a die in the pressing stage, does not carry out secondary accurate correction on the nested caulking rings, is easy to deviate due to factors such as vibration, centrifugal force and the like in the material transmission process, and further reduces the pressing assembly precision; 3. The equipment has low automation degree, wherein working procedures such as material feeding, pressing triggering, discharging and the like lack linkage control, the driving part is required to be controlled manually or independently to realize material transmission after the pressing is finished, and the telescopic action and the material transmission of the embedded ring limiting structure do not have cooperative action, so that the whole processing efficiency of the equipment is low, and the manual intervention cost is high; 4. The thin-wall part has poor lamination stability, and aims at the problems that the thin-wall high-pressure-resistant caulking ring is thin in base material thickness and low in structural strength, the conventional lamination equipment lacks a flexible lamination and clamping structure, the caulking ring is easy to deform, the cover surface is concave and the like in the lamination process, and the product yield is influenced. Based on the defects of the prior art, the pressing assembly equipment for the thin-wall high-pressure-resistant embedded ring and the easily-pulled cover surface, which can realize accurate positioning, secondary correction and automatic linkage transmission of the embedded ring, is designed at present to solve the technical problems of low pressing precision, poor automation degree and low product yield of the existing equipment. Disclosure of Invention Aiming at the defects of the prior art, the invention provides laminating assembly equipment for a thin-wall high-pressure-resistant caulking ring and a cover surface of a pop-top cover, which solves the problem that the lamination of the conventional caulking ring is inaccurate.
