Method and device for forming objects from a material strand and for separating said objects

Abstract

The invention relates to a device for forming objects from a material strand (1) and for separating said objects. The device comprises a mould (5) for forming a relief (10) in one section (21) of the material strand, a separation device (6) for separating the reliefs (10) that have been formed by the mould (5) and a transport device for transporting the material strand through the mould (5) and the separation device (6). A device (11, 12, 13) for producing a reference characteristic (22) in the material strand (1) is located outside the mould (5) and is coupled to the latter. The separation device (6) comprises a detection device (16, 17) for detecting the position of the reference characteristic, which is assigned to a first relief, in the strand (1) and a cutting tool (14, 15) that can be positioned using the detected position of the reference characteristic (22).

Description

technical field [0001] The invention relates to a method and a device for working shaped articles, in particular by deep drawing, from a strip of material and subsequently separating the articles. Background technique [0002] Production devices are known for the mass production of articles from flat metal or plastic materials, by means of which a strip of raw material unrolled by a storage drum is conveyed step by step along a conveying section and first passes through a mould. , the profile of the article to be manufactured is formed in the associated material strip, and then the material strip located between the front and rear profile parts is separated in a cutting device, thereby obtaining the finished product. It is of the utmost importance for such a device that the incisions produced by the cutting device between the individual profile parts follow exactly the predetermined edges of the article to be produced. Any deviations in the position of the cutouts beyond th...

AI Technical Summary

Problems solved by technology

Since this accuracy cannot be estimated simply, it cannot be satisfactorily taken into account when designing the structure of the article to be produced, and may require costly modifications to the structure and, if necessary, to the mold used

[0005] This problem is further exacerbated by the fact that when designing the structure of an article to be produced in such an apparatus it is generally sought to avoid sharp edges, since these edges are still formed during or after the article is formed. It may be easy to form a breakpoint in the use of
