Description

Technical Field

[0001] The present invention relates to the field of cutting technology, and more particularly to a plasma high-efficiency cutting device. Background Art

[0002] A plasma gas cutting machine is a thermal processing device that uses a high-temperature, high-speed plasma arc to cut metal. It offers advantages such as high cutting speed, a small heat-affected zone, high-quality cuts, and compatibility with a wide range of materials. In the hydraulic sector, plasma cutting devices are also used in the manufacture of devices such as gates, particularly for the plasma cutting of plate materials such as gate plates.

[0003] During plasma cutting, the high-temperature arc rapidly melts a localized area of ​​the material being cut. Simultaneously, the high-speed compressed airflow blows the molten metal and impurities, such as oxides, out of the cut kerf. This causes them to splash everywhere, contaminating the cutting platform and the work environment. Furthermore, the heat from the high-temperature arc passes through the material being cut and is transferred to the cutting platform, adversely affecting it. Summary of the Invention

[0095] The base plate 5 is mounted with multiple first and second detection units, each equally spaced. The number of first detection units equals the number of support modules in a row. The first detection units comprise two first mounting plates 7.1 fixedly connected to the base plate 5, a first laser emitter 7.2 mounted on one of the first mounting plates 7.1, and a first light receiver 7.3 mounted on the other first mounting plate 7.1.

The material receiving hopper 8.5 has a ceramic coating, such as a boron nitride coating. The sidewalls of the material receiving hopper 8.5 contain water cooling channels, both ends of which are connected to the cooling water circulation system.

[0096] Working Principle: As shown in the figure, the cutting device of this application has multiple support modules on the base plate, and each support module is installed with a support rod. Under normal circumstances, the lifting block is attracted by the strong magnetic block on the top block, so that the top ends of the multiple support rods can be used to support the plate. Although the plate has a certain weight, the weight of the plate is distributed among the multiple support rods. The lifting block where each support rod is located is attracted by the multiple strong magnetic blocks, thereby achieving support for the plate.

[0097] When cutting is required, the cutting scene is mostly linear cutting. According to the position to be cut, the adjustment unit is driven to lower the multiple support rods below the cutting seam. Specifically, Figure 5 As shown, the adjustment unit installed between the two first fixed beams drives the first movable beam to translate, and cooperates with the first electric lifting rod and the first electric push rod to insert the first insertion rod into the first insertion hole of the limit rod of the support module in a row, so that the first electric lifting rod descends and can pull down the support rod in a row, so that Figure 8 As shown in FIG, the lifting blocks of the support modules of this column abut against the bottom blocks. Figure 11As shown, the first insertion rod of the adjustment unit disengages the first insertion hole of the support module in this row and returns to its initial position. Furthermore, multiple first laser emitters, multiple first light receivers, multiple second laser emitters, and multiple second light receivers can detect whether the support rods that need to be in the raised position (for convenience, the state where the lifting block is abutted and attracted by the magnetic block is referred to as the raised position) are in the raised position, and whether the support rods that need to be in the lowered position (for convenience, the state where the lifting block abuts the bottom block is referred to as the lowered position) are in the lowered position. Subsequently, the plasma cutting unit, driven by the second and third moving units, cuts the desired location. During cutting, a material receiving hopper can be positioned below the plasma cutting unit, providing negative pressure suction to absorb the molten metal and impurities such as oxides produced during cutting. Because the support rods at the cutting location are in the lowered position, they are less susceptible to the high temperatures generated during cutting, thereby protecting the carrier unit.

[0098] Reversing the adjustment unit can restore the support rods in the lowered position to their raised position. When cutting in another direction is required, the adjustment unit between the two second fixed beams can be used to adjust the position of the support rods. In some scenarios, curved or diagonal cuts are required. As shown in the figure, the drive motor, lead screw, second electric lift rod, and second electric push rod in the adjustment unit between the two first fixed beams can drive the second plunger to lower the support rods one by one, placing them in the lowered position. This allows the required cut to be performed. Under normal circumstances, the two adjustment units can lower a row or column of support rods, resulting in high processing efficiency. In some special cases, the second plunger can be used to lower the support rods one by one, allowing multiple support rods arranged in a diagonal or curved pattern to be lowered. In their initial position, both adjustment units are located below the substrate, protecting them from falling molten metal and oxide impurities.
