The essence of the invention is that the burner consists of two rings interacting with each other (2 and 3), one of which (2) is immovable, has mounting feet (7) by means of which it is placed on a coating (1), whereas the other (3) rotates on the immovable one. The two rings keep in touch with each other by means of roller bearings. The rotating ring (3), driven by an electric motor (4), is equipped with a beam (5). Two torches (14 and 16) moving vertically along a bar (18) are fixed to the beam (5). The bar (18) runner (22) moves horizontally along the beam (5) by means of a slide (8). The position of the torches against the centre of the ring is determined by the radius of a hole to cut. The slope of the torches results from an angle of bevelling. The distance between the torches and the curved surface of a material to cut (1) is being adjusted, while cutting, by the sliding bar (18) driven by a stepper motor (23) controlled by a proximity sensor (15), placed at the bar (18).

Description

Portable burner for cutting holes in curved and flat coatings
The subject matter of the invention is a portable burner for cutting holes out of curved and flat coatings, especially holes for connectors in the metal coatings of tank-type apparatus, using an oxygen, plasma or other type of torch.
The known ways of cutting holes by burning in curved steel coatings, as well as the bevelling of their edges outside the specially prepared stationary workstation (CNC burner with a special head) generally consist in line-marking the edge of a hole and its centre, next, using compasses with a torch fastened to it, in manual operating the torch, holding the compasses attached to the centre of the hole. These ways, particularly with regard to bigger holes (of a diameter more than 0.5m) fail to get the exact geometry on account of the curvature of a coating, causing the tilt of compasses. The bevelling of the edge of a hole for welding the connector on (e.g. for type x bevelling) involves two consecutive revolutions of the torch operated by hand. The preparation of the bevelled areas for welding after the manual cutting takes a lot of time and effort. Also the welding after the manual cutting involves, as a rule, filling up the excessive gaps resulting from this kind of cutting .
The purpose of the invention is to avoid line-marking and the manual cutting of holes by means of compasses, as well as the manual bevelling of holes. Cutting a hole out using the subject matter burner allows to cut a hole automatically along with proper bevelling in one go of the torch (two torches at type x bevelling). In consequence, it will much improve the quality of the holes cut and the bevelling of the holes edges, as well as considerably will reduce the costs of energy and time spent on performing the task.
The essence of the invention is reflected in the design of the burner. It consists of two rings interacting with each other, one of which is immovable, has mounting feet by means of which it is placed on a coating, whereas the other is rotating on the immovable one. The two rings keep in touch with each other by means of a roller bearing. The rotating ring, driven by an electric motor, is equipped with a beam. Two torches moving vertically along a bar are fixed to the beam. The bar runner moves horizontally along the beam by means of a slide. The position of the torches against the centre of the ring is determined by the radius of a hole to cut. The slope of the torches results from an angle of bevelling. The distance between the torches and the curved surface of a material to cut is being adjusted while cutting by the sliding bar driven by a stepper motor controlled by a proximity sensor, placed at the bar.
The rings, one immovable and the other rotating, can be either in the form of metal sheets, or open profiles of any cross section, or pipes of any cross section. The rings interact with each other by means of rolling balls, cylinders, or pulleys. The rotating ring can be replaced by two elements supporting the beam, moving on the immovable ring, or by one element to support the beam, moving on the immovable ring. The object of the invention is depicted in the following figures:
Fig. 1 - burner with a beam supported by a rotating ring,
Fig. 2 - burner with a beam supported by two elements,
Fig. 3 - burner with a beam supported by one element.
The burner consists of an immovable bottom ring (2) which is to be mounted by means of four mounting feet (7) on a coating to cut (1), and an upper ring (3) rotating on the bottom one (2) by means of a roller bearing. It is driven with an electric motor (4) placed on the upper ring (3) the gear wheel (35) of which interacts with the gear insert (34) placed on the bottom ring (2). The upper ring (3) bears a beam (5) attached to it by means of clamps (9). The beam supports torches and a laser guided by a swivelling arm (6).
The supporting set of the torches consists of a primary slide (8) moving along the beam (5) with the help of a winder knob (19) interacting with a gear bar (21) fixed to the beam (5). The slide is attached to a runner (22) on a vertical sliding bar (18) which is combined with a horizontal bar (10). The combined bars (18 and 10) move vertically in the process of cutting, according to the curvature of a coating (1). They are driven with a stepper motor (23) interacting with a gear bar (20) combined with the vertical bar (18). The stepper motor (23) is controlled by signals coming from a proximity sensor (15) which is attached to the horizontal bar (10). It specifies the torches position against the surface of a coating to cut. The vertical bar (18) bears torch A (16) by means of a clamp (27) making it possible for the torch to move along its axis, using a winder knob (26) combined with a gear bar (25) attached to torch A (16). The clamp (27) along with torch A (16) can move at an angle in a plane parallel to the beam (5) and the vertical bar (18), and its position is adjusted by a screw (17). The horizontal bar (10) combined with the vertical one (18) bears a slide (13). The slide has a clamp (28) fixed along with torch B (14), which makes it possible for the torch to move along its axis, using a winder knob (29) combined with a gear bar (30) attached to torch B (14). The clamp (28) along with torch B (14) can move at an angle in a plane parallel to the horizontal bar (10), and its angle position is specified with the help of a screw (12). Once the position of torch B (14) on the horizontal bar (10) is established, the slide (13) is adjusted by a screw (11).
In the variety of the burner depicted in Fig. 2, the rotating ring (3) has been replaced by two elements (36 and 37) supporting the beam (5), moving on the immovable ring (2).
In the variety depicted in Fig. 3, the beam (5) is supported by one element (38), moving on the immovable ring (2). In order to cut a hole out in a given coating, the centre of the hole to cut need to be punched or otherwise marked in the form of a point. The laser (32) guiding the torches provides the appropriate mounting of the burner via the coaxial alignment of the burner rings (2 and 3). The laser (32) is positioned in a cavity (31) inside the beam (5). This is the passive position. The laser (32) is fixed on the swivelleng arm (6) attached to the beam (5) by means of a coupling pin (24). While guiding, the swivelling arm (6) must be put out of the cavity (31) to its maximum outer position. This is the active position. In this position the laser (32) is switched on. Its ray (33) is then in the axis of the rings (2 and 3). Next, the laser ray (33) is directed to the focal point of the hole of a coating (1). After mounting the burner on a coating to cut a hole in, the swivelling arm (6) of the laser (32) is put to the passive position in the cavity (6). Then, the process of cutting can be proceeded to. Two torches are used for cutting holes with type X bevelling. When the edge of the hole is supposed to be plain or type V bevelling, one torch is used, and the other can remain as auxiliary or be dismantled.
