[0001] The invention relates to the technical field of plasma cutting, and in particular to a cutting platform and a plasma cutting machine. Background Art

[0002] When the plasma beveling machine is cutting steel plates, the cutting table itself is not level, and some steel plates are too long, causing bulging in the middle or at the edges.

[0053] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0054] In the process of cutting steel plates, the plasma beveling machine in the prior art has the phenomenon of bulging in the middle or at the edge of the steel plate due to the unevenness of the cutting table itself and the excessive length of some steel plates. The bevel size of the steel plate is often inconsistent, and the bevel angle changes, causing the entire plate to be scrapped. This not only affects the cutting accuracy of the entire plate, but also increases the cost. Laying electromagnets on the entire workbench will also increase production costs, that is, it is easy to cut the electromagnets under the steel plate to be cut.

[0055] In this embodiment, a plasma cutting machine is provided, including a cutting platform. A steel plate to be cut is arranged on the cutting platform, and a plasma cutting head is used to cut the steel plate, so that the groove of the cut steel plate remains consistent, the cutting accuracy is ensured, and the production cost is reduced.

[0056] like Figure 1-Figure 6As shown, the cutting platform comprises a support 1, a placement platform assembly 2 and a steel plate adsorption device 3, wherein the support 1 is arranged on the ground. The placement platform assembly 2 is arranged on the support 1, and the placement platform assembly 2 is configured to support the steel plate to be cut. The steel plate adsorption device 3 is arranged on the support 1, and the steel plate adsorption device 3 is selectively arranged in the placement platform assembly 2 and is located below the steel plate. The steel plate adsorption device 3 can adsorb the steel plate to be cut, and can release the steel plate at a preset time and descend to a preset distance below the steel plate.

[0057] When the steel plate is cut on the cutting platform in this embodiment, the steel plate is placed on the placing platform. Since the entire steel plate itself is not flat, during the cutting process, the steel plate adsorption device 3 under the steel plate is used to adsorb the uneven position of the steel plate, so that the entire steel plate remains flat. After cutting, the groove is kept consistent, the cutting accuracy of the entire plate is consistent, and the cost can be reduced.

[0058] In addition, during the cutting process, since the above-mentioned steel plate adsorption device 3 is located below the steel plate, in order to ensure that the steel plate adsorption device 3 is not cut during cutting, when cutting is near the steel plate adsorption component, the steel plate adsorption device 3 can automatically descend to a preset distance from the bottom of the steel plate, which neither affects the cutting accuracy of the steel plate nor can it ensure that the steel plate adsorption device 3 is not cut.

[0059] An adjustable component 4 is provided between the placement platform component 2 and the bracket 1, and the adjustable component 4 can adjust the relative position between the placement platform component 2 and the bracket 1. The adjustable component 4 in this embodiment is a screw, and the placement platform component 2 is provided with a screw, and the relative position between the placement platform component 2 and the bracket 1 can be adjusted by adjusting the screw.

[0060] The placement platform assembly 2 comprises a plurality of support plates 21 arranged on the bracket 1, the length direction of each support plate 21 being perpendicular to the length direction of the steel plate, the plurality of support plates 21 being arranged in parallel and spaced in sequence along the length direction of the steel plate, and the steel plate adsorption device 3 being selectively arranged between two adjacent support plates 21. The plurality of support plates 21 are arranged in parallel to support the steel plate together. At least one steel plate adsorption device 3 is arranged between two support plates 21 at each interval of a preset number of support plates 21.

[0061] Specifically, the placement platform assembly 2 further includes an insert plate 22 disposed on the bracket 1, a plurality of support plates 21 are inserted in parallel on the insert plate 22, and the adjustable assembly 4 is disposed on the insert plate 22. The length direction of the insert plate 22 is arranged along the length direction of the steel plate, a plurality of slots are arranged on the insert plate 22, a plurality of the insert plates 22 are arranged in parallel, a support plate 21 is inserted in a plurality of slots, and the insert plate 22 and the support plate 21 are arranged vertically.

[0062] Because the steel plate is uneven, after the steel plate is placed on the support plate 21, it is necessary to first adjust the plug plate 22 to drive the support plate 21 to move, so that the support plate 21 can make the steel plate as flat as possible, and then use the above-mentioned steel plate adsorption device 3 to partially adsorb the steel plate, so that the entire steel plate tends to be more completely flat. The above-mentioned adjustable component 4 is arranged on the support plate 21, and each support plate 21 is selectively provided with an adjustable component 4, and the distance between the support plate 21 and the bracket 1 in the vertical direction is adjusted by the adjustable component 4 to adapt to the support steel plate.

[0063] In order to facilitate the steel plate adsorption device 3 to adapt to steel plates with different deformations, the steel plate adsorption device 3 needs to be adjusted in position. In this embodiment, the steel plate adsorption device 3 is slidably arranged on the bracket 1. The steel plate adsorption device 3 can reciprocate along the width direction of the steel plate to adapt to different positions where different steel plates need to be adsorbed.

[0064] Specifically, the cutting platform also includes a guide assembly arranged on the bracket 1, and the steel plate adsorption device 3 is arranged on the guide assembly, and the guide assembly can drive the steel plate adsorption device 3 to slide back and forth in a direction perpendicular to the length direction of the steel plate. More specifically, the guide assembly includes a slide rail and a slider, and the length direction of the slide rail is arranged perpendicular to the length direction of the steel plate. The slider is slidably connected to the slide rail, and the steel plate adsorption device 3 is arranged on the slider. In other embodiments, the guide assembly can also include a motor, a lead screw and a sliding block, and the motor is arranged on the bracket 1, one end of the lead screw is connected to the output end of the motor, and the other end is rotatably connected to the bracket 1. The sliding block is rotatably connected to the lead screw, and the steel plate adsorption device 3 is connected to the sliding block.

[0065] The steel plate adsorption device 3 includes a driving member 33 and an intermediate connecting component 31, one end of which is connected to the output end of the driving member 33. The electromagnet component 32 is arranged in the intermediate connecting component 31, and the intermediate connecting component 31 can adjust the relative position of the electromagnet component 32 and the output end of the driving member 33 so that the electromagnet component 32 can be adsorbed and attached to the steel plate. Preferably, the driving member 33 is a cylinder. In this embodiment, the electromagnet component 31 is an electromagnet. The steel plate adsorption device 3 also includes a shell, and the shell cover is arranged on the outside of the intermediate connecting component 31.

[0066] Since the steel plate is in a bulging state, the lower surface of the steel plate is not parallel to the cutting platform, and there is a certain angle. When the upper surface of the electromagnet contacts it, the two surfaces cannot be completely fitted. At this time, even if the electromagnet is in a magnetized state, it cannot add too much suction to the steel plate, and the downward pulling force of the cylinder may cause the two to disconnect. In response to this problem, an intermediate connection component 31 is added between the electromagnet and the cylinder. The intermediate connection component 31 consists of an external frame 311, an internal movable part 312 and an elastic part 313. The external frame 311 and the output end of the driving part 33 are fixed, the internal movable part 312 and the electromagnet are fixed, and the elastic part 313 is placed between the two. After setting the distance, when the cylinder moves upward to the maximum stroke, the top of the electromagnet exceeds the plane of the cutting table by 10mm. In the normal cutting process, since a steel plate is placed on the placement platform component 2, the top of the electromagnet moves to the lower plane position of the steel plate and cannot continue to move upward. At this time, the lower surface of the steel plate will exert a force on the elastic member 313, and the elastic member 313 will deform elastically in the direction of the force, so that the upper surface of the electromagnet and the lower surface of the steel plate tend to be parallel, and then fit closely. In this embodiment, there are four elastic members 313, which are springs, and the four springs are arranged in parallel.

[0067] The working principle of the above cutting platform:

[0068] Before placing the steel plate on the support plate 21, the adjustable component 4, i.e., the screw, is used to adjust the support plate 21 to keep it in a horizontal state. After the steel plate is placed on the placement platform component 2, the cylinder moves upward, the upper surface of the electromagnet contacts the steel plate to be cut on the cutting table, and then the electromagnet is magnetized, the electromagnet attracts the steel plate, and the cylinder moves downward, pulling the steel plate so that its bulging part fits the cutting table surface.

[0069] The position coordinates of the steel plate adsorption device 3 are pre-stored in the control system, and the control system can control the action of the steel plate adsorption device 3 to adapt to steel plates with different position deformations. In addition, when the steel plate is cut to the vicinity of the position of the steel plate adsorption device 3, the control system can control the cylinder to descend, thereby driving the electromagnet assembly 32 to descend, thereby avoiding damage to the steel plate adsorption device 3. This control system is a conventional control system and is not a technical innovation in this application, and will not be repeated here.

[0070] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
