Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plasma cutting, in particular to a support structure of a cutting platform and a plasma cutting platform. BACKGROUND

[0002] Plasma cutting is to make the metal part or partial melt and evaporate at the cutting position of the workpiece by using the heat of the high-temperature plasma arc. Before cutting, the plate to be cut is placed on the support structure of the cutting platform, and then the plasma cutting is performed on the plate.

[0003] At present, the support structure of the cutting platform used in mechanical processing is generally composed of a mounting frame and a plurality of slide rails arranged in parallel and spaced apart on the mounting frame, and two support columns are slidably arranged on each slide rail. When in use, first, the positions of the support columns on the two slide rails are adjusted so that the four support columns are located at the four corner positions of the plate after cutting, and then the plate is placed on the four support columns according to the predetermined position to perform cutting.

[0004] When cutting, the cutting head needs to cut along the periphery of the plate. When the cutting head moves directly above the slide rail, the molten iron formed by the melting of the plate will directly drop on the slide rail and solidify into an iron block to block the subsequent movement of the support column, resulting in that the spacing and density of the support columns cannot be adjusted according to the operation needs. SUMMARY

[0005] Therefore, the technical problem to be solved by the present application is to overcome the defect that when the cutting head moves directly above the slide rail, the molten iron formed by the melting of the plate will drop on the slide rail and solidify into an iron block to block the subsequent movement of the support column during the support and cutting of the plate by the cutting platform in the prior art, so as to provide a support structure of a cutting platform and a plasma cutting platform.

[0006] In order to solve the above technical problem, the present application provides a support structure of a cutting platform, comprising:

[0007] a mounting frame;

[0008] a slide rail mounted on the mounting frame, the slide rail having a plurality of parallel and spaced apart;

[0009] a support column slidably mounted on the slide rail, the support column being provided with a flow interception structure on at least the side surface located directly above the slide rail, the flow interception structure protruding outwardly from the support column in the radial direction, and the flow interception structure having a flow guide groove extending to the outside of the area directly above the slide rail.

[0010] Optionally, the area of the top of the support column for supporting the plate to be cut gradually decreases upwardly.

[0019] Optionally, the rectangular slot has a downward opening, and the slide rail can be separated from the rectangular slot through the opening.

[0020] A plasma cutting platform comprises:

[0021] A housing having an installation slot with an upward opening inside;

[0022] The support structure of the cutting platform according to any one of the above solutions is installed at the upper opening end of the installation slot.

[0030] 1. The support structure of the cutting platform provided by the present invention allows the molten iron formed by the melting part of the plate to drip directly onto the guide groove of the interception structure when the cutting head moves directly above the slide rail. This allows the molten iron to flow along the guide groove to the outside of the slide rail, thus preventing the molten iron from dripping directly onto the slide rail.

The flat structure is in surface contact with the plate, and the plate has good stability after being placed on the support column. At the same time, the flat structure itself is small, which can further avoid the cutting head from damaging the support column body and ensure that the support column can be reused.

[0033] 4. The plasma cutting platform provided by the present invention, by using the support structure in the above solution, can adjust the spacing and density of the support columns according to different plates, so that the plasma cutting platform can cut plates of different sizes. Furthermore, since molten iron will not drip onto the slide rail, it can ensure that the plasma cutting platform always maintains a normal state and the support columns can be adjusted at any time, so that the plates can be cut smoothly.

[0034] 5. The plasma cutting platform provided by the present invention, by setting a dust removal hood on the mounting slot, allows gas to enter from the air inlet, forming a circulating air curtain in the mounting slot, which carries up the dust in the plasma cutting area, and then discharges the dust and gas mixture from the air outlet.

[0035] 6. The plasma cutting platform provided by the present invention has a detachable scrap cart at the bottom of the mounting slot. The scrap cart can collect the molten iron and iron filings generated during the cutting process. Afterwards, only the scrap cart needs to be cleaned, making the working environment of the plasma cutting platform cleaner. BRIEF DESCRIPTION OF DRAWINGS
