Description

Technical Field

[0001] This utility model relates to the field of plasma air gouging technology, and specifically to a plasma air gouging device. Background Technology

[0002] A plasma air gouging device is a device that uses a high-temperature plasma arc to melt metal and then blows away the molten metal with a high-speed airflow, thereby creating grooves or cleaning specific areas on the metal surface. Its core components include a plasma power supply, an air gouging torch, an air supply system, and a control system.

[0003] A CNC plasma cutting and air gouging processing device, disclosed in CN222552832U, relates to the technical field of plasma air gouging processing devices. It includes a first fixed plate, a first fixed block fixedly installed at the top center of the first fixed plate, a gear rotatably installed at the center of the first fixed block, a first slider slidably provided on one side of the upper part of the first fixed block, and a first toothed plate fixedly installed at one end of the first slider. The first toothed plate meshes with the first gear. This utility model includes a first clamping plate, a second clamping plate, and a third clamping plate. When an electric push rod moves the sheet material, the gear, the first toothed plate, the second toothed plate, and the third toothed plate cooperate to fix the first clamping plate and the second clamping plate on both sides of the sheet material, thus fixing the sheet material. This solves the problem that existing methods of fixing processed sheet materials mostly rely on bolts and fixed plates to clamp and fix the four corners of the sheet material, which is inconvenient, cumbersome, and reduces processing efficiency.

[0004] The existing technology has the following shortcomings: When processing metal parts, the metal parts heated by the plasma arc cannot be cooled down quickly after processing. This makes it easy for workers to be burned when handling and replacing the metal parts due to the high temperature, which will affect the safety of the workers. At the same time, the inability to quickly replace the hot metal parts will affect the air gouging efficiency of the metal parts. Utility Model Content

[0027] This utility model provides, for example Figure 1 The plasma air gouging device shown includes a device body 1, and further includes:

[0028] The placement mechanism 2 is located at the bottom inside the device body 1, and the processing mechanism 3 is located at the top inside the device body 1.

[0029] To ensure rapid cooling of machined metal parts, such as Figure 1-2 and Figure 4 As shown, the placement mechanism 2 includes a ventilation plate 201. An adjusting screw 203 is positioned in the middle of the ventilation plate 201. A first motor 204 is mounted at one end of the adjusting screw 203. Clamping plates 205 are threaded onto the outer sides of both ends of the adjusting screw 203. A support plate 206 is fixedly installed at the bottom of the ventilation plate 201. Five rotating shafts 207 are rotatably mounted on the top of the support plate 206. Cooling fans 208 are fixedly sleeved onto the outer sides of the top of each of the five rotating shafts 207. Transmission sprockets 210 are fixedly sleeved onto the outer sides of the bottom of each of the five rotating shafts 207. A transmission chain 211 is sleeved between three transmission sprockets 210 at the same height. The rotating shaft 204 in the middle... A second motor 209 is installed at the bottom of 07. The first motor 204 drives the adjusting screw 203 to rotate, which can drive the two clamping plates 205 to move relative to each other or in opposite directions, so that the two clamping plates 205 can clamp and fix the metal workpiece. After the processing is completed, the second motor 209 drives the adjacent rotating shaft 207 to rotate. Through the transmission action of three transmission sprockets 210 and transmission chain 211 at the same height, the other four rotating shafts 207 rotate accordingly, so that the five cooling fans 208 can cool the workpiece on the top of the ventilation plate 201, which can facilitate the workers to pick up and replace the metal workpiece.

[0030] To prevent the fumes generated during processing from spreading everywhere, such as Figure 1-3 As shown, the device body 1 includes a fixed base 101. A control panel 102 is fixedly installed on the outer wall of one end of the fixed base 101. A placement groove 103 is opened on the top of the fixed base 101, and the placement groove 103 is fitted onto the outside of the ventilation plate 201. A collection box 108 is placed on the bottom inner side of the fixed base 101. A fixing plate 104 is fixedly installed on one side of the outer wall of the fixed base 101. Fixing brackets 105 are fixedly installed at both ends of the top of one side of the outer wall of the fixing plate 104. A dust suction hood 106 is movably inserted into the bottom of the fixing plate 104. An exhaust pipe 10 is fixedly installed at one end of the dust suction hood 106. 7. The bottom end of the exhaust pipe 107 penetrates the outer wall of the fixing base 101 and communicates with the inside of the collection box 108. The ventilation plate 201 can be installed and fixed through the placement slot 103. The control panel 102 can control the first motor 204 and the processing mechanism 3 to work, and can perform air gouging on metal parts. At the same time, the dust suction hood 106 can transport the fumes generated during the processing to the inside of the collection box 108 through the exhaust pipe 107. The exhaust pipe 107 is equipped with a fan, which can conveniently absorb and transport the fumes, and can prevent the fumes from spreading to the surrounding area.

[0031] To facilitate the processing of different locations on metal parts, such as Figure 1-3 and Figure 5 As shown, the processing mechanism 3 includes two hydraulic cylinders 302, which are respectively fixedly installed at the top ends of one side of the outer wall of the fixed plate 104. Movable plates 301 are fixedly installed on one side of the piston rods of the two hydraulic cylinders 302. The outer walls at both ends of the movable plates 301 are slidably connected to the inner walls of the two fixed brackets 105. A fixed rack 303 is fixedly installed at the bottom of the movable plate 301. A movable seat 304 is sleeved on the outer side of the movable plate 301. A third motor 305 is fixedly installed on one side of the outer wall of the movable seat 304. A movable gear 306 is fixedly sleeved on the outer side of the output shaft of the third motor 305. The movable gear 306 meshes with the fixed rack 303. A movable groove 307 is opened on one side of the movable seat 304. An electric push rod 308 is fixedly installed on the top of the inner wall of the movable groove 307. A mounting plate 309 is fixedly installed at the bottom of the piston rod. An air planer nozzle 310 is movably inserted into the inner side of the mounting plate 309. The operation of two hydraulic cylinders 302 can drive the movable plate 301 to move along the inner side of the two fixed frames 105, which can adjust the longitudinal position of the air planer nozzle 310. The third motor 305 drives the movable gear 306 to rotate. Through the meshing action between the movable gear 306 and the fixed rack 303, the movable seat 304 moves laterally outside the movable plate 301, which can adjust the lateral position of the air planer nozzle 310. At the same time, the operation of the electric push rod 308 can drive the mounting plate 309 to move up and down, which can adjust the height of the air planer nozzle 310, so that the air planer nozzle 310 can conveniently perform air planing on different positions of the metal workpiece.

[0032] In order for the clamping plate 205 to stably clamp the workpiece, such as Figure 2 and Figure 4 As shown, a mounting groove 202 is provided in the middle of the ventilation plate 201. The inner wall of the mounting groove 202 is rotatably connected to the adjusting screw 203. The inner walls at both ends of the mounting groove 202 are slidably connected to the bottom outer walls of the two clamping plates 205. The mounting groove 202 can install and fix the adjusting screw 203. The outer threads at both ends of the adjusting screw 203 are opposite, so that the clamping plates 205 can move relative to or away from each other on their outer sides. At the same time, the mounting groove 202 can limit the movement of the clamping plates 205, so that the two clamping plates 205 can stably clamp and fix the metal workpiece.

[0033] When performing air gouging on a metal workpiece, the workpiece is placed on top of the ventilation plate 201. The control panel 102 drives the first motor 204 to rotate the adjusting screw 203, causing the two clamping plates 205 to move relative to or away from each other along the inner wall of the mounting groove 202. This clamping plates 205 clamp and fix the metal workpiece. Then, the control panel 102 extends or retracts the two hydraulic cylinders 302, which moves the movable plate 301 along the inner side of the two fixed brackets 105, adjusting the longitudinal position of the air gouging nozzle 310. Simultaneously, the control panel 102 controls the third motor 305 to drive the movable gear 306 to rotate. Through the meshing action between the movable gear 306 and the fixed rack 303, the movable seat 304 moves laterally on the outside of the movable plate 301, which can adjust the lateral position of the air planer nozzle 310. The control panel 102 controls the electric push rod 308 to extend or retract, which can drive the mounting plate 309 to move up and down along the inner wall of the movable groove 307, which can adjust the height of the air planer nozzle 310, so that the air planer nozzle 310 can perform air planing on different positions of the metal workpiece.

[0034] During processing, the fan attached to the exhaust pipe 107 operates, allowing the fumes generated during processing to enter the exhaust pipe 107 through the dust extraction hood 106 and be transported to the collection box 108 via the exhaust pipe 107. This prevents the fumes from spreading and affecting the surrounding environment and workers. After processing is completed, the control panel 102 causes the second motor 209 to drive the adjacent rotating shaft 207 to rotate. Through the transmission action of three transmission sprockets 210 at the same height and their outer transmission chains 211, the other four rotating shafts 207 rotate accordingly, thereby driving the five cooling fans 208 to rotate. This cools the metal parts placed on top of the ventilation plate 201, allowing the metal parts heated by the plasma arc to cool down quickly. This makes it easier for workers to pick up and replace the metal parts, thereby improving the efficiency of air gouging of the metal parts. This embodiment specifically solves the problem in the prior art where the metal parts processed by plasma air gouging cannot be cooled down quickly, making it difficult for workers to quickly replace the processed parts.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
