Description

A kind of orthoscopic tank mouth former

Technical field

This utility model relates to a kind of tank mouth former for canister, and so-called tank mouth shaping is primarily referred to as the tank oral area to canister and completes the processing of necking down forming process, also can extend the subsequent handling processing such as increase flange, crimping or enlarging on necking down Process base。

Background technology

Canister, such as pop can, generally have aluminum matter and irony two kinds, and its structure is made up of can body and lid (easy-open lid)。In order to reduce the cost of easy-open lid, convenient vanning and transport simultaneously, the can body of the canister circulated in the market all can carry out necking down operation, 9 places in necking down structure such as Fig. 1。Furthermore, in order to add a cover to can body, it is possible to also need overturning process on necking down basis, for Bottle & Can, also need the operations such as enlarging, crimping。

Necking down forming technique is mainly based upon multi-drop mould necking down, namely by multiple tracks mould extrusion process, makes tank mouth reduced diameter, until reaching the neck size of final requirement。Being reduced to 202 with the tank cervical region of main flow on market by 211, neck thickness 0.148mm is example, it is necessary to 12 road necking down operations can complete。

In prior art, necking down equipment is as shown in Figure 2, the running route of jar 1 is the curve that wriggles, whole cervical region former is made up of modular forming unit one by one, each unit is again by multiple stations, such as 8, 10, 12, 16 are waited composition, they are all for completing with forming process, the station of each forming unit is made up of essentially identical a set of push-rod assembly and mould jumper bar assembly, they complete the cervical region forming process of jar under the control of space cam, then by carrying star-wheel that jar is delivered to next forming unit, until jar finish dimensional reaches shape and the size of requirement, finally, cervical region shaped after jar sent this former by exporting star-wheel。One main feature of this equipment is: speed of production is high, but shortcoming is each unit cost height, especially, for Bottle & Can popular gradually, only necking down needs 30 multiple working procedures at least, needs 40 multiple working procedures at most, and the acquisition cost of complete equipment is fairly expensive。But, for the Production requirement of Bottle & Can or inhalator jar, owing to production lot is little, it is not required to too high speed of production, but needs less expensive cost, this occur as soon as a kind of demand to low speed, low-cost equipment。
