Description

Multi-channel easy-opening automatic stamping production line

The invention relates to a multi-channel easy-cover automatic stamping engineering design scheme and a production line, and is particularly suitable for constructing a metal stamping automatic stamping production line of 4 channels, 6 channels, 8 mm, 10 channels and ^± even channels.

Background technique

Metal easy-to-tank is a widely used beverage packaging material on the market. According to relevant information, there are more than 320 billion disposable metal beverage cans in the world, and more than 250 per capita consumption of beverage metal cans in the United States and other developed countries; China consumes 15 beverage metal cans per capita per year. The demand for beverage metal cans in developing countries is increasing at a high speed, and there is huge market space. Metal Easy Cover is an indispensable key component of the easy-to-cans. There are five main production technologies in the metal stamping production technology:

1) The ring-type forming of the high-speed punching machine of Yongtai is completed synchronously, the basic cover has been formed by the element forming and the riveting process of the pull ring, and the 1 channel system produces 2 2-channel systems with easy-covering scheme;

2) Single high-speed punching machine completes the forming of the pull ring synchronously, the basic cover has been formed by the element forming and the riveting step of the pull ring, and 1 punching process produces 3 3-channel systems with easy cover solution;

3) Single high-speed punching machine completes the pull ring forming synchronously' The basic cover has been formed with the element forming and the ring riveting step, and 1 punching process produces 4 4-channel systems with easy cover solution;

4) The sub-machine program, the sub-machine is attached to the mother machine, and is driven by the main machine main shaft. The sub-machine completes the drawing of the pull ring. The main machine is synchronized to complete the basic cover and the riveting step of the pull ring, and 1 punch produces 3 easy a 3-channel system with a lid;

5) 1 + 1 scheme, one high-speed punching machine completes the forming of the pull ring, and another high-speed punching machine completes the basic cover-easy element forming and the riveting step of the pull ring. Two high-speed punches work synchronously, and one punch produces four easy The 4-channel system of the cover scheme.

In the first three-flushing scheme, the progressive direction of the easy-to-clamp element forming and the progressive direction of the tab forming are perpendicular and asymmetrically arranged, which makes the punching pressure unbalanced, and the pressing force of the easy-fitting element and The punching force of the pull ring riveting can not be balanced, resulting in serious eccentric load during the stamping process; thus, the production quality of the most critical parts of the easy-covering cover is unstable, and the reactive power load is not fully utilized. It also restricts the further expansion of production capacity. In the fourth scheme, although the problem of eccentric load caused by the stamping of the pull ring is effectively solved, the unbalance of the pressing force of the easy-to-twist element and the punching pressure of the pull ring is not solved; at the same time, due to the punching of the punching ring The sub-machine is attached to the easy-to-use element forming punching machine and driven by the main machine main shaft, which also limits the capacity of the equipment to further increase the production capacity. Although the fifth solution effectively solves the problem of eccentric load caused by the stamping of the pull ring, it does not solve the balance problem of the pressing force of the easy-to-crush element and the punching pressure of the pull ring; and the two high-speed punches need to work synchronously, and the operation is complicated. Equipment at the same time It does not contribute to the improvement of production capacity, and the investment cost is high.

A review of the deficiencies of the prior art:

1) There is a serious eccentric load in the stamping process, which leads to unstable production quality of the easy-to-smash elements, which is easy to cause batch waste accidents, and excessive quality costs are unavoidable;

2) The eccentric load in the stroke is more severe with the increase of the number of channels, increasing the reactive power loss, and exerting the full effect of high-speed punching, which leads to the industry bottleneck problem that has not broken through 4 channels in a β high-speed punching machine. It is difficult to meet the growing market demand;

3) The stability of the equipment and mold is challenged by the eccentric load, the operation and maintenance cost is high, and the number of shutdowns is frequent;

4) In terms of investment-output ratio, investment costs are high;

5) Easy to cover as a one-time consumer goods manufacturing cost is too high.
