Description

Support and travel arrangement for flame cutting machines.

Object of the invention

The present specification refers to a application for an Invention Patent corresponding to a support and displacement arrangement for flame cutting machines, whose purpose is to get from it, a rigidity in the displacement of the structure constituted by the guide bridge on the sides that configure the support and the area of displacement of the bridge and the chassis of the machine of igniting you in question.

The invention presents the quality of correcting of adequate lack of punctual parallelism.

Field of the Invention

This invention has its application within the industry dedicated to the manufacture of cutting machines by Oxycut and plasma.

Background of the invention

The machines intended to make cuts on sheet, have a plurality of performances, ranging from the mechanical construction until arriving at the civil works, contemplating its application also for the conduction and repair of diverse machinery, and even for the manufacture of sculptures in steel.

So far, the cutting machines by Oxycut and plasma intended for cutting sheet metal, presented systems of translation and guidance, both of the transverse axis and of the axis longitudinal, using ball bearings on guides heated.

The need for adjustment is currently verified inherent in the use of ball bearings, especially in the shaft transversal of this type of machines, since in the transversal axis It is where the cutting heads are located, which when placed close to the material to be cut are likely to be hit, with which the guiding means are continuously adjusted, inexcusably requiring the intervention of a technician maintenance.

Consequently, some machines of this type they use linear guides and ball recirculation skates in the transverse axis.

It has been found that the biggest problem that exists in this type of machines is motivated when the width of it requires the use of a second motor on the shaft longitudinal.

When you build a machine in the form of double motorized gantry means that the parallelism between raceways have to be perfect, since when mounting engines in the two translation trains, any parallel failure it affects the synchronization of the motors and the movement of the machine, even stopping it when the engine is forced.

The mismatch of the raceways, perfectly calibrated in the installation of the machine, it is motivated by the continuous blows that the machine suffers when loading and Download sheet metal from the cutting table.

Since it is inevitable that these occur blows, it would be necessary to have an invention that would allow assume small and medium parallelism failures in machines with double motorization in the longitudinal axis.

However, so far you do not have knowledge of the existence of an invention that presents the features described in this report.

Description of the invention

The support and travel arrangement for flame cutting machines that the invention proposes, avoid the lack of parallelism and at the same time reduce the mismatches that can paralyze the production.

More specifically, the support arrangement and displacement for flame cutting machines is constituted from of a movable bridge and a bench, presenting rails by which the motionless bridge moves longitudinally, with its relevant chassis constituting the main body where it performs the transverse movement of the cutting stations and in the which houses all command, control and management operations of cutting and movement.

The machine's mission is to mobilize the cutting stations at the top of the material to be cut, in order to achieve the cutting of any type of geometry in two dimensions.

The machine can have one or several cutting stations, either flame cutting or plasma cutting.

It should be noted that when the machine incorporates more than one cutting station, adjustment of the measure is required between the different torches, this adjustment of manually operated by pneumatic actuation or automatically by numerical control.

The fixing of the bed is done by use of anchor plugs directly on the ground, and a Once set, it is calibrated in straightness, level and parallelism.

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, is accompanied herein descriptive, as an integral part of it, a set of planes in which with an illustrative and non-limiting nature, it has been represented the following:

Figure number 1.- Represents a view in perspective of the flame cutting or plasma cutting machine, in which the object of the invention corresponding to a support and displacement arrangement for machines Oxycut

Figure number 2.- Represents a view in perspective of the support arrangement.

Figure number 3.- Corresponds to an exploded view. of the object represented in figure number 2.

Preferred Embodiment of the Invention

In view of these figures, it can be seen how the support and displacement arrangement for machines Oxycut is constituted from support pieces (1) that in number of two they are fixed to the ground and on them they they incorporate plates (2) from which vertical pieces are drawn (3) placed in parallel, on which tubular bodies are fixed (6) that have guide rails at the top (7), incorporating on one of the sides a body (4) located lengthwise that takes the form of a "U", by which the chain that generates the longitudinal mobilization of the bridge (8) by mobilizing the chain (5), having the bridge (8) a chassis or frame and control elements (10) and (11) among which the numerical or manual control is contemplated by pneumatic drive to make the torches (9) be properly place to make the requested cut over the plates that are located at the bottom of the bridge (8).

The bridge is supported on stones (14) that they move on the rails (7), presenting an external bellows (13) and a hollow piece (12) of quadrangular plan that in collaboration with an angular plate (15), a plate (16), acting this plate (16) as the axial tube joint plate, It is implemented with an axial bearing (18), a gasket (17), as well as with a piece (20) that presents means of support in its hollow ends in its central area, where a piece is incorporated (19) that presents cylindrical pronunciations at its ends.

All these pieces allow the displacement of the bridge in collaboration with the metal part (14) which is what displaces, it should be noted that the angular plates (15) are intended to make the relevant fixations.

Claims (2)

1. Support and displacement arrangement for flame cutting machines, of those constituted from a mobile bridge (8), equipped with several torches (9) and incorporating a chassis or frame where the control panels (10) and ( 11) configured as numerical control and manual control elements by pneumatic actuation, characterized by being constituted from parts (1) that are adjacent to the surface longitudinally, and laterally to the bridge (8), on which plates (2) are provided with vertical pronunciations (3) that support tubular bodies (6) located in parallel on which rails (7) are fixed for the displacement of the bridge (8) in a longitudinal direction, presenting pieces (14) positioned on the rails (7) in which a bellows (13) and a tubular body (12) are fixed that is fixed to the bridge (8), presenting on one of the sides and adjacent to one of the tubular bodies (6) bearing in the top of the travel rail (7), a hollow body (4) that takes the form of a "U", through whose inner zone a travel chain (5) is mobilized. 2.
