Description

Die cutter for carpentry profiles metallic

Object of the invention

The present invention relates to a machine die cutter, of those used in carpentry workshops metal and similar to punch metal profiles for Obtaining aluminum windows and doors.

The object of the invention is to provide a die cutting machine that allows machining different types of holes easily, with a tongue or reduced die Cost and easily interchangeable.

Background of the invention

In the practical scope of the invention, that of metalwork, manufacturers and workshops dedicated to the construction of windows and doors with aluminum profiles and use for miter joint of said profiles of expansion, blocking or spring brackets, they need to machine on the miter tips of the window profile, door or frame two holes, in order to serve as a grip for the techos of the squad, also called "back" and housing and subsequent tightening of the square bolt or "Forward". In this way, the inner square will make the union between the two profiles at 90 ° is perfect. The same happens in the union with squares of variable angle.

To do this, manufacturers have matrices manual, mechanical, pneumatic or hydraulic, single or multiple that they have to acquire from matricería manufacturers or the sells or deposits the supplier of the squares or the supplier of the aluminum profiles, however there are companies that their own matrices are manufactured.

These mechanisms are basically composed of some punches (square, rectangular, round, etc,) of steel tempered pushed by lever, pneumatic or hydraulic mechanisms and even by external means to the die cutting machine itself, against the tongue or die, also made of tempered steel, thus achieving the die cutting of the aluminum profile that interpose between them.

The fundamental problem presented by this type of devices is the great variety that exists of models of profiles used to obtain doors and windows, at that you have to add the own designs of some workshops, which it implies the need to machine different types of cameras or holes, of different sizes and geometries, for each of the which is essential to use a tongue or matrix determined.

These tabs or dies must be machined with maximum precision, in addition to being obtained from a High quality material for subsequent tempering. Another point important is that the tongue should be machined in width about tenths of a millimeter less than the chamber to be punched, so that when introduced, the profile is as guided as possible, avoiding possible punching errors.

This implies a high manufacturing cost for the tabs or matrices, as well as the need to have as many tabs as series of profiles you work with, tabs that, as previously stated, have to be replaced every time you want to make a camera of different settings or dimensions, substitution that is slow and laborious, and that requires great precision, since a perfect centered of it with respect to the punches so that these when going down do not impact against it, so sometimes there are workshops that prefer to have several punching machines with different tabs, with the consequent cost that it supposed.

Equally noteworthy is the fact that in the if the die cuts in the profile are offset, it is it is necessary to use a pair of tabs per system, doubling the cost of manufacturing and buying as well as the time of machine change

Finally it should be noted that trying to obviate there are certain gadgets on the market that make thick, made of steel or aluminum, to supplement these deficiencies, which are also expensive to mechanize and that neither They cover a wide range of profiles or cameras.

Description of the invention

The die cutter for carpentry profiles metal that the invention proposes fully resolves satisfactory the aforementioned problem, incorporating a universal tongue that, thanks to its special structuring allows the machining of different types of cameras, all with reduced costs, thanks to a simple solution but of great effectiveness.

To do this the die cutting machine that advocates, that being independently manual, hydraulic or pneumatic, focuses its characteristics on the fact that it incorporates a narrow tongue with a flat recess in its anterior area on which a pair of magnets and a pair of cylindrical pins.

Said cylindrical pins will guide a sheet intended to be implanted thereon, being fixed by Magnets effect.

The sheet will have an interchangeable character as well as a reduced cost, so that existence is planned of sheets with different widths, of magnitudes according to the internal chamber of the machining profile, taking into account that, as It has already been mentioned before, this magnitude should be tenths of a millimeter smaller than said camera, allowing to have a large stock of sheets for different machining, and reducing noticeably waiting times in the supply of a new type of sheet before a new possible use of the workshop, all this due to the structural simplicity of them.

In the case of having to make die cut off-center, the tongue holes corresponding to the pins will also be made off-center, so that a simple 180 ° rotation of the sheet allows both to be punched hands.

In this way with a single tongue you can mechanize different types of profiles, simply by changing the sheet associated with it, very simple and quick replacement to perform, without tools, all with a reduced cost

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows a perspective view of a die cutter made in accordance with the purpose of the invention.

Figure 2.- Shows an exploded perspective. of the die cutter of figure 1.

Figure 3.- Shows a view similar to that of Figure 1 but with a profile of a door or window instants before being machined

Figure 4.- Shows a view similar to that of Figure 3, once the profile has been machined.

Figure 5.- Shows, a detail in perspective of the universal tongue and associated elements to it they participate in the die cutter of the invention.

Preferred Embodiment of the Invention

In view of the figures outlined you can be observed as the die cutter object of the invention, being of any type as far as its drive is concerned, is constituted from a support (1) formally and dimensionally suitable for fixing a tongue (2) of reduced thickness, to through guide screws (3) through holes (4) practiced in said tongue, with interposition of an element ejector (5).

Said ejector element is provided, as is conventional, of holes (6) acting as guides for respective punches (7) movable vertically on the tab (2) through any drive means conventional, punches that in the machining are introduced in blind holes (8) operatively set in the tongue (2).

Well, according to the invention, the tongue (2) incorporates a stepped recess (9) on its face upper and anterior in which a pair of magnets are established (10) as well as a pair of cylindrical pins (11), preferably with a diameter of the order of four millimeters.

Said stepped recess (9) of the tongue (2) it will have a thickness in accordance with the sheet (12) to which it is intended to receive, of a metallic nature, sheet equipped with a pair of through holes (13), formally and dimensionally suitable for adapting to cylindrical pins (11), of so that through them and by the effect of the magnets (10), the sheet is perfectly stabilized in conditions of operation of the machine, resulting in an easy element and Quickly interchangeable without tools.

As can be seen in Figure 2, the pins (11) will be established over blind holes (14) practiced on the tongue (2), which may be arranged longitudinally or not centered, depending on the stamped to obtain, so that when these have to be Off-center, a simple turn of the sheet (12) of 180 ° will allow die cut with one hand or another.

The magnets (10) will also be housed in blind holes (15) operatively machined on the tongue (2).

Finally, the fact that the plates (12) will have different widths (16) according to the internal chambers of metal profiles (17) to be machined, in order to ensure centered on them, all as it is You can see in figures 3 and 4.
