Description

This utility model pertains to auxiliary production equipment. The device is designed for thermal cutting of materials with additional ventilation of the work area.

A known prior art device is a lamella table with a smoke extraction system. It is installed on the work surface and allows for processing across the entire 800 x 800 mm working area of your machine, as well as securely clamping the material. It is compact and easy to use. Its purpose is to collect waste during laser cutting and protect the working area from the laser beam. The exhaust table is also equipped with special clamps that securely hold the workpiece and provide additional material alignment, ensuring high-quality cutting. The working surface is also adjustable, allowing it to be installed on the machine's working area without worrying about unevenness of your sacrificial sheet (https://savinsname.ru/catalog/optsii/vspomogatelnoe_oborudovanie/lamelnyy_stol_s_vytyazhnoy_kameroy_800/). This development is the applicant's own.

The closest technical solution is RU 2325251 C2, which is a table for thermal cutting of sheet material. This table pertains to equipment for the thermal (plasma, laser) processing of flat blanks made of various materials and comprises a working surface in the form of a grid of vertical metal plates supported by a frame, at least one air duct located below the grid parallel to the side walls of the frame, and a device equipped with a drive for removing gaseous and solid cutting waste. The device includes a container for collecting solid cutting waste, located under the grid, placed with a gap in a casing open at the top, mounted with the possibility of reciprocating movement parallel to the side walls of the frame. A longitudinal slotted groove is formed in the air duct, facing the grid and provided at the edges with elastic flanges abutting each other, and the bottom of the casing is provided with at least one slotted pipe, parallel to the side walls of the frame and entering the longitudinal slotted groove of the air duct.

The closest to the technical solution is RU 179866 U1, which is a device for removing gaseous and solid products of laser cutting, containing parallel boxes formed on the sides by vertical metal plates, and below by a horizontal metal bottom, made with a means for pumping air out of them, characterized in that it is equipped with nozzles installed with the possibility of alternately supplying pulses of compressed air into the boxes from their side opposite from the placement of the air pumping means.

All existing variants of such solutions are part of the general design of industrial thermal cutting machines. This is all necessary for processing large, heavy sheet materials with high heat generation, primarily for sheet metal processing. The claimed low-profile design is intended for processing thin and light sheets on lightweight machines, but it does not allow for processing heavy materials with high heat generation.

The technical result is the development of a table for thermal cutting of sheet material of limited height with a lower-mounted exhaust chamber, allowing for rapid installation and dismantling of equipment in the working area for the effective removal of combustion products from the processing area.

In order to achieve the said technical result, a table was developed for thermal cutting of sheet material, comprising a working surface in the form of a grid of metal plate elements, along the perimeter of which longitudinal holders and connecting transverse ribs are installed fastened together, a welded pallet (1), forming a single whole with an exhaust manifold (2), to which a flange for connecting an exhaust line (3) is attached, characterized in that it is equipped with a distribution cover with openings of different diameters, located over the entire working area of the cover (5), installed in a niche of the said pallet with the formation of an exhaust chamber space under it, which is connected to the exhaust manifold, wherein the said plate elements are made in the form of a set of support strips (6), which are inserted with their ends into the grooves of spacer strips (10), made on the longitudinal holders (7), and in the corners of the said grid, adjusting eccentrics (9) are installed, attached by means of screws to the transverse ribs (8) with the possibility of adjusting the inclination of the working surface (Fig. 4).

The essence of the claimed utility model is explained in the presented drawings:

Fig. 1 shows a general view,

where the following positions are present:

1 - welded pallet

2 - exhaust manifold

3 - exhaust line

4 - plug

5 - distribution cover

6 - set of support strips

Fig. 2 shows the desktop,

where the following positions are present:

6 - support strips

7 - longitudinal holders

8 - connecting transverse ribs

9 - adjusting eccentrics

10 - spacer strips.

Fig. 3 shows the installation of support strips,

where the following positions are present:

6 - support strips

7 - longitudinal holders

10 - spacer strips

Fig. 4 shows the adjustment of the tilt of the working plane,

where the following positions are present:

8 - connecting transverse ribs

9 - adjusting eccentrics

The device works as follows.

The design of the support bars allows the workpiece to be positioned within the work area and prevents waste from entering the exhaust chamber, trapping it within the work area. The work table with support bars can be either fixed or removable, and the work surface angle can also be adjusted. In this model, the work surface height is adjustable at four angles by rotating eccentrics. The exhaust manifold has one or more flanges for connecting the ventilation duct, which is installed at the top or bottom. Any unoccupied outlets are closed with a plug.
