Description

Technical Field

[0001] The present application relates to the field of cutting machines, and in particular to a plasma cutting machine with a safety protection mechanism. Background Art

[0002] A plasma cutting machine is a machine that uses plasma cutting technology to process metal materials. Plasma cutting is a processing method that uses the heat of a high-temperature plasma arc to partially or partially melt the metal at the workpiece cut, and then uses the momentum of the high-speed plasma to expel the molten metal to form the cut.

[0003] When using a plasma cutting machine to cut metal materials, the cutting process will produce sparks and debris, which will splash onto the human body and cause damage to the human skin. At the same time, when the plasma cutting machine cuts metal materials, it will produce toxic gases. Once the toxic gases are inhaled into the human body, they will cause certain damage to the human body. For this reason, we have proposed a plasma cutting machine with a safety protection mechanism.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0023] See also Figure 1-5 The present application provides a plasma cutting machine with a safety protection mechanism, including a machine body 10, a U-shaped frame 20 capable of horizontal movement is installed on the top of the machine body 10, a plasma cutting mechanism 30 is installed on the U-shaped frame 20, and a protective plate 40 is inserted into one side thereof, a gas purification mechanism 50 is installed on the protective plate 40, and a baffle 60 is installed on the other side of the U-shaped frame 20. Specifically, the U-shaped frame 20 moves horizontally, which can drive the protective plate 40 and the baffle 60 to follow the movement, and the horizontal movement method of the U-shaped frame 20 is the existing technology. The gas purification mechanism 50 is installed on the protective plate 40, which can absorb the air inside the protective plate 40 to achieve the purpose of purifying the air.

[0024] See Figure 1 and 2 The protective plate 40 is set in a U shape, and a space that can accommodate the plasma cutting mechanism 30 is formed between it and the baffle 60. When set, the protective plate 40 can be set to be transparent to facilitate observation of the movement state of the plasma cutting mechanism 30 in the space, and the sparks generated during the cutting process are blocked by the protective plate 40 to prevent the sparks from flying upwards.

[0025] See Figure 1 and 6 Two plug-in blocks 210 are installed on one side of the U-shaped frame 20, and both plug-in blocks 210 are provided with T-shaped slots 220. Both ends of the protective plate 40 are T-shaped and are respectively inserted into the two T-shaped slots 220. It should be noted that the top of the T-shaped slot 220 is open, so that the T-shaped end of the protective plate 40 can be inserted into the T-shaped slot 220 from above, so as to facilitate the disassembly and assembly of the protective plate 40.

[0026] See Figure 1 and 3 The gas purification mechanism 50 includes an intake duct 510 fixedly mounted on the inner wall of the protective plate 40 and a purification component 520 mounted on the outer wall of the protective plate 40. The intake duct 510 is U-shaped and has a plurality of intake holes 530 thereon. The purification component 520 is connected to the intake duct 510. Specifically, the purification component 520 can generate negative pressure, thereby causing the plurality of intake holes 530 to generate suction to absorb the air inside the protective plate 40. Furthermore, the intake duct 510 is arranged near the bottom of the protective plate 40, and a filter (not shown in the figure) is installed in the intake hole 530 to prevent sparks and debris from entering the intake duct 510.

[0027] See Figure 4 and 5 The purification component 520 includes a purification pipe 5210 and a fan unit 5220 installed on the outer wall of the protective plate 40. A plurality of ducts 5230 are connected between the fan unit 5220 and the side wall of the purification pipe 5210. The purification pipe 5210 includes a U-shaped plate 5211 fixedly installed on the outer wall of the protective plate 40. A mounting block 5212 is inserted into the U-shaped plate 5211. A plurality of through-holes 5213 are opened on the mounting block 5212. One end of the plurality of through-holes 5213 is connected to the suction pipe 510, and the other end thereof is connected to the plurality of ducts 5230 respectively. In the specific setting, the fan unit 5220 includes a box body with an open top, a plurality of fans are installed in the box body, and the plurality of ducts 5230 are connected to the bottom of the box body, so that when the fan is working, a negative pressure is generated at the bottom of the box body, and the mounting block 5212 can be inserted into the U-shaped plate 5211, thereby facilitating the disassembly and assembly of the mounting block 5212.

[0028] See Figure 4 and 5 Filter elements 5214 are inserted into the inlet ends of several through-ports 5213, and several activated carbon plates 5215 are respectively inserted into the outlet ends. The filter elements 5214 are arranged in a frame shape. When set, the filter elements 5214 and the activated carbon plates 5215 can be inserted into the through-ports 5213 from both sides of the through-ports 5213. The filter element 5214 is arranged in a frame shape as a whole, with one end sealed and the other end open to achieve the purpose of filtering.

[0029] When the plasma cutting machine with a safety protection mechanism is in use: when the plasma cutting mechanism 30 is working, the fan group 5220 is started at the same time to generate negative pressure in the several ducts 5230, and then absorb the air inside the protective plate 40 through the several suction holes 530, and further absorb the smoke generated in the cutting process. After the smoke is filtered by the filter element 5214, it will pass through the activated carbon plate 5215 to filter out harmful components and finally be discharged from the fan group 5220. The sparks and debris generated in the cutting process are blocked by the protective plate 40 and the baffle 60 to prevent them from splashing upwards.

[0030] It should be noted that the specific model specifications of the plasma cutting mechanism 30 and the fan group 5220 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0031] The power supply and principle of the plasma cutting mechanism 30 and the fan unit 5220 are clear to those skilled in the art and will not be described in detail here.

Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
