KR0159826B1 - Method and apparatus of forming irregular wrinkle on metal net or foil - Google Patents

Abstract

The invention is a pleated irregular crease directly in the creation and production of ornaments, ornaments and art.

This invention is made while passing through the passage (10) to the place where the metal foil or the metal net is passed through the gap (5) of the two smooth rotary rolling rolls (2, 3) and stopped by the stop (4).

This process involves joining the metal foil or the metal net between the two smooth rolling rolls (2,3) at regular times without any gaps and then starting the machine to the end of the passage (10) under the continuous stop of the stopper (4). Subsequently, it is pushed forward by the rotation of the machine.

The present invention relates to a method for forming irregular wrinkles of metal foil or metal mesh in the production and creation of ornaments, ornaments, and art works.

The invention also relates to the use of a machine for the rolling of metal foil for the production of irregularly pleated structures of ornaments, ornaments and art, as in the way of already produced jewelry crafts.

Until now, the production of irregular wrinkles on the surface of jewelry, ornaments, and crafts, which were produced by materials such as metals, was only possible by auxiliary work such as modeling or casting techniques.

This work process was accompanied by loss of time and waste of materials, and was not sharp and precise wrinkles as can be seen in the works produced so far.

The production of regular corrugated structures by various materials-for example, corrugated paper by paper or the like, corrugated tin by thin tin plate, etc.-is widely known.

This product was also stamped with paper or tin by a rolling machine by an auxiliary material, a corrugated machine. (DE-OS 2042855, DE-OS 2107981, DE-OS 2932713)

Regular corrugated paper was also crimped as it was continuously pushed through the passages by a particularly smooth rolling machine (DE-AS 1028426).

The creation of regular wrinkled ornaments and handicrafts of the same type produced in this way is of little interest, and the surface structure of the form has a tedious effect.

In addition, the production of metal foil (DE-OS 3228181) in the auxiliary material of a wobble mill structure suggests a surface that is always repeated.

An object of the present invention is to provide a method for irregularly forming wrinkles on a surface of a metal foil, a metal mesh, etc., which is used to solve the above problems and used in the creation of ornaments, ornaments, arts, etc. in a simple and economical manner It is done.

In order to achieve the above object, the present invention includes raising the upper rolling roll (2) to increase the gap between the upper rolling roll (2) and the lower rolling roll (3), the upper rolling roll (2) and the lower rolling Transferring the metal foil or the metal mesh to the exit guide plate 7 between the rolls 3, pressing the metal foil or the metal mesh downward by pressing the upper rolling roll 2, and the upper rolling roll 2 and Rotating the lower rolling roll (3) provides a method for irregularly forming a wrinkle on the metal foil or metal mesh, characterized in that consisting of the step of transferring the metal foil or metal mesh toward the stopper (Stopper).

In addition, the rolling means consisting of the upper rolling roll (2) and the lower rolling roll (3), the guide plate 6 for guiding the metal foil or metal mesh, and forming a passage (10) between the guide plate (6) Provided is a cover box (8), and a stopper (4) for stopping the metal foil or metal mesh to provide an apparatus for forming irregular wrinkles in the metal foil or metal mesh.

Hereinafter, the present invention will be described in detail with reference to Examples.

EXAMPLE

A convenient conventional apparatus for rolling metal foils is used for the production of crafts of irregular creased structure.

In this apparatus, a stopper for stopping the metal foil or the metal net is provided at the end of the passage.

The metal foil or the metal mesh is formed by the rolling of the rolling rolls while passing through the gap between the two rolling rolls.

The low cost, technical invention can be used for very thin metal plates, such as gold, silver or copper.

The present invention can also be used as a metal mesh woven with a metal wire, for example, a metal wire woven with gold, silver, copper wire or the like.

The spacing, shape and depth in the corrugation can vary depending on the choice of metal material used.

That is, depending on the thickness and type of the metal plate, or the metal mesh according to the thickness of the metal wire, it is possible to adjust the rotational speed and change the width of the passage according to the choice of the appropriate use case.

The irregular corrugated metal products produced by this invention are bent or diversified in shape, and are widely used in various ways of ornaments, ornaments, and art works. For example, rings, earrings, necklaces, bracelets, etc., and wrinkled metal plates or metal meshes can be processed in various ways. In other words, the corrugated copper plate or silver plate is crimped and plated.

Rolling of metal plates for the production of irregularly corrugated crafts is carried out using machines with additional stops. However, it is conceivable that rolling mills suitable for precious metal crafts (H. Seltsam Sohn, Pforzheim, Germany) can also be produced for the production of irregularly wrought crafts.

The machine used is two smooth, rotating rolling rolls 2.3, the upper rolling rolls 2 being adjustable in the direction of the arrow 9. The adjusting device adjusts the gap between the gaps 5 of the two rolling rolls 2 and 3. 0.03 or 0.04 mm, for example. The device has a guide plate 6 on the inlet side and a guide plate 7 on the outlet side for the metal foil 1. The cover box 8 is covered by the upper rolling roll 2 in the apparatus on the outlet side. This makes a passage together with the guide plate 7. There is a stop 4 on the exit guide plate 7 or the cover box 8. In particular, as an iron plate, it can be fixed or adjustable (Figure 1).

In addition, it can be used by inserting into a small gap of the passage 10 with a steel wedge from the stationary table 4 (FIG. 2).

Fabrication of Crafts with Irregular Wrinkle Structures-As depicted in detail 3, the following examples are given.

The metal foil 1 pushes the beginning of 0.05 mm thickness between the rolling rolling rolls 2 and 3 on the guide plate 6 of the entrance side. The upper rolling roll 2 rotated here is adjustable. After that, the metal foil 1 is brought into close contact with the rear face of the exit cover box and bent. Immediately to the folded metal foil 1, the steel plate 4 of the stopper is pushed in the direction of the arrow 11.

Guide plate 7 on the exit side and the cover box 8 of the upper rolling roll 2 are tightened while sitting on the upper rolling roll 2 without a gap with the passage 10 interposed therebetween. According to the above procedure, the metal foil in the gap 5 between the rolling rolls 2 and 3 is pressed. The rolling rolls 2 and 3 under the holding | maintenance of the stationary stand 4 pinch | rotate with metal foil interposed.

At this time, if the rolling rotation speed is about 25 revolutions per minute, the metal foil passed between the rolling rolls 2 and 3 in the passage 10 continues to be pushed out, resulting in an irregular wrinkle structure.

Loosen the stopper (4), loosen the machine and remove the irregularly corrugated metal foil from the machine. It is also used as jewelry (details 4).

At this time, the metal foil 1 is pushed by the rotation in the passage 10 without being bent and fixed between the lid box 8 and the stopper 4, and irregular wrinkles are caught. )

The present invention configured as described above is a useful invention that can reduce the work process and manufacturing cost by simply forming a wrinkle on the metal surface.
