Multi-channel easy-open lid automatic stamping engineering design scheme and production line

Abstract

The invention relates to a multi-channel easy-open lid automatic stamping engineering design scheme and a production line, particularly suitable for constructing a metal easy-open lid automatic stamping production line with 4 channels, 6 channels, 8 channels, 10 channels or more even channels. An easy-open lid stamping channel group A (1) and a channel group B (2) in opposite progressive directions are arranged in parallel on a high-speed punch; the same numbers of forming channels are respectively arranged on the channel group A (1) and the channel group B (2), and the progressive directionsof all the forming channels on either channel group are the same. The invention solves the eccentric load problem of easy-open lid stamping, constructs the automatic stamping production line with 6 channels, 8 channels, 10 channels or more even channels on the high-speed punch, decreases the investment cost and manifolds the yield and the quality stability of the single stamping line, wherein theyield of the production line with 6 channels is larger than 3600 pieces / min, the yield of the production line with 8 channels is larger than 4800 pieces / min, and the yield of the production line with10 channels is larger than 6000 pieces / min.

Description

technical field [0001] The invention relates to an automatic stamping method and production line for multi-channel easy-open lids, and is particularly suitable for the construction of an automatic stamping production line for metal easy-open lids with 4 channels, 6 channels, 8 channels, 10 channels and more even-numbered channels. Background technique [0002] Metal easy-open cans are currently widely used beverage packaging materials in the market. According to relevant data, the annual consumption of beverage metal easy-open cans in the world exceeds 320 billion pieces, and the annual per capita consumption of beverage metal easy-open cans in the United States and other developed countries is more than 250 pieces; China Annual per capita consumption is 15 beverage metal easy-open cans. The demand for beverage metal easy-open cans in developing countries shows a rapid increase trend, and there is a huge market space. Metal easy-open end is an indispensable key component of ...

Problems solved by technology

[0015] The purpose of the present invention is to completely solve the problem of stamping eccentric load caused by the unbalanced punching force of the easy-opening element forming, the forming of the pull ring and the riveting step of the pull ring and the easy-open cover in the automatic stamping production line of the easy-open end; The industry problem of high-speed and stable production of open element molding and the industry bottleneck problem that has not yet broken through the 4-channel automatic stamping production line on a high-speed punching machine; provide a high-speed punching machine that can realize 6-channel, 8-channel, 10-channel and The above-mentioned automatic stamping method and production line for easy-open end with even-numbered channels doubles the production capacity to solve the shortcomings of the existing technology

The symmetrical structural design of the two channel groups solves the problem of stamping eccentric load caused by the unbalanced stamping force of the easy-opening elements, the stamping force of the tab forming and the stamping force of the tab riveting that cannot be solved by the microstructure design from the macroscopic layout. Due to the bottleneck restriction of the industry, an automatic stamping production line for easy-opening caps with 6 channels, 8 channels, 10 channels and above even-numbered channels can be built on a high-speed punching machine
