Description

Combined servo high-speed synchronous driving multi-station tank neck forming equipment

Technical Field

The invention relates to a tank opening forming device of a metal tank, in particular to a combined servo high-speed synchronous driving multi-station tank body neck forming device. The neck forming mainly includes a necking step for forming the mouth of the can body, and may further include a subsequent processing step of expanding and increasing a flange, a curl or a flare in addition to the necking step.

Background

With the improvement of living standard of people, the pop cans are more and more used in the fields of food and beverage, and particularly, the pop cans are more common in beer and beverage packaging. The pop can is composed of a can body and an easy-open lid, wherein in order to reduce the weight of the easy-open lid and the cost of the easy-open lid and facilitate boxing and transportation, the can body circulating in the market at present is subjected to necking processing. Moreover, in order to cap the can body, flanging processing may be required on the basis of necking, and in the case of bottle cans, flaring, curling and other processing are required.

The neck molding of the can requires a set of multi-station neck molding equipment, which comprises a plurality of die extrusion processes to gradually reduce the diameter of the can mouth until the final required neck size is reached. Necking stations, flanging stations, can bottom forming stations, light inspection stations, etc. are commonly included in multi-station neck forming equipment. These stations are combined to form a multi-station neck molding line. Where the necking station is the core of the apparatus, at least two necking stations are typically required.

Along with the development of canning trade, the production speed requirement of market to neck former is higher and higher now, wants to realize higher speed production, and the key is that the smooth transportation handing-over of jar body between standing and standing when solving high speed ensures that can not appear jar body by extrusion damage, fall jar, card jar scheduling problem. Those skilled in the art know that in order to make the can bodies smoothly transit and handover between stations under high speed conditions, the transmission timing sequence of the equipment transmission chain is required to have higher control precision, so that the normal operation of the can bodies on the equipment transmission chain can be ensured.

However, the existing can neck forming devices (including necking, flanging and the like) on the market basically drive the executing components through distributed driving and gear transmission chains, so that the aim of transferring the cans to carry out multi-stage necking and flanging forming is fulfilled. Neck forming apparatuses such as those described in US patent 9308570B2 entitled high speed necking formation (high speed necking formation) operate using a distributed drive and gear train. However, those skilled in the art will recognize that there are limitations to improving transmission timing accuracy control by using distributed drive and gear train operation. Because the distributed driving adopts a combination form of a common motor and a speed reducer, the synchronism of a plurality of motors in the work has deviation and is difficult to control. On the other hand, a gear transmission chain is adopted, particularly, a gear transmission with a steel gear and a nylon gear meshed is adopted in the gear transmission chain for avoiding lubrication, and because the accuracy of the gear is limited by machining accuracy, errors exist, and the steel gear and the nylon gear also have the problem of thermal expansion, which can directly influence the high-speed transferring and handing-over of the tank bodies between stations.

In view of the above, it is an object of the present invention to improve the prior art to improve the transmission timing accuracy control of a multi-station can neck forming apparatus under high-speed operation conditions.
