The plasma cutting machine can cut various metals which are difficult to cut by oxygen cutting, especially has better cutting effect on non-ferrous metals.

[0003] H-shaped steel is necessary steel material for construction, and after processing, the plasma cutting machine is used to cut and expand the side of the H-shaped steel to ensure that the H-shaped steel can be effectively connected with the remaining parts by fastening bolts. Since the side of the H-shaped steel is arc cut, in order to ensure that the hole expansion of the H-shaped steel is completely punched, continuous cutting work is required, which will cause the cutting machine to cut the horizontal surface of the H-shaped steel and the adjacent side through the hole, and thus cause obvious black marks on the surface of the H-shaped steel, and the side spraying sparks are easy to cause production accidents, so improvement is needed.

[0032] Further, the transfer component further comprises,

[0033] The transmission roller shafts are symmetrically provided with synchronous motors at both ends, and the outer surface of the synchronous motor is fixedly connected with the inner cavity of the vertical frame plate through the adaptive clamping groove.

[0034] The suction component is arranged on the middle part of the upper surface of the bundling bottom plate, and is used for preventing sparks generated by cutting from splashing outwardly, the transmission roller shafts are uniformly arranged on the top of the vertical frame plate, but a group of vertical frame plates in the middle part of the bundling bottom plate are replaced by the suction component, and since the transmission roller shafts are arranged relatively closely, the missing of a group of transmission roller shafts will not affect the transfer work of the processed steel.

[0035] Further, the suction component comprises,

[0036] The bottom end of the bundling suction cylinder is fixedly connected with the middle part of the upper surface of the bundling bottom plate, and the two sides of the air inlet of the bundling suction cylinder are symmetrically provided with bent connecting pipes.

[0037] The vertical push rod is slidably connected to the shaft of the height-adjusting push cylinder;

[0039] The beneficial effects of the present application are as follows:

[0040] 1. The device cuts and expands the side of the processed steel material through the cutting torch nozzles on both sides. When the cutting torch nozzles continuously apply high-temperature heat energy, unnecessary heat cutting work is performed on the horizontal surface and the adjacent side of the processed steel material through the hole that has not been completely penetrated, thereby causing obvious black marks on the surface of the processed steel material, and the sparks from the side spray can easily cause production accidents. Therefore, a receiving component is arranged in the middle region of the processed steel material and is connected to the cutting torch nozzle, thereby preventing the flame of the cutting torch nozzle from penetrating the processed steel material and the sparks from splashing into the inside region of the processed steel material, thereby protecting the inside region of the processed steel material from the high-temperature flame of the cutting torch nozzle and avoiding the above problems.

[0041] 2. Since the suction cylinder can provide a certain adsorption capacity to the expansion outer cylinder on both sides through suction, the flame and sparks penetrated by the cutting torch nozzle are guided to the inside of the expansion outer cylinder, so that the expansion outer cylinder can also have effective adsorption effect without closely contacting the processed steel material, thereby ensuring that the processed steel material can be smoothly transported without rubbing against the side of the expansion outer cylinder, thereby preventing the problem of wear of the expansion outer cylinder. After the cutting torch nozzle finishes processing, the adsorption effect of the drainage pipe can drive the external air to quickly cool the flared opening of the processed steel material, thereby preventing the problem of burns caused by high temperature when workers check the flared opening of the processed steel material.

[0042] 3. When the suction cylinder needs to be cooled after working for a period of time, the suction work is stopped, at which time the rebounding drainage inner pipe completely blocks the built-in partition, and only the shielding effect of the expansion outer cylinder covers the penetrating flame sprayed by the cutting torch nozzle. Since the two ends of the horizontal connecting pipe are isolated from the outside under the action of the built-in partition, it is difficult for the horizontal connecting pipe to conduct heat, thereby preventing the problem of overheating damage caused by long-term continuous absorption work of the suction cylinder.

[0043] 4. When the processed steel material is transported to the central region for cutting and flaring, and then during the working of the cutting torch nozzle, the arc-shaped filter plate is attracted to the outer surface of the arc-shaped filter plate by the suction of the suction cylinder, so that the total amount of the sparks splashed outside is greatly reduced, and the production accidents caused by the external splashing sparks are avoided, and at the same time, the arc-shaped filter plate can adsorb the toxic gas generated by cutting to the inside of the suction cylinder, avoid the diffusion of toxic gas to the production workshop, cause the problem of damage to the health of personnel, and play the function of safe production.

In the cutting process, the electrode generates an electric arc, and the nozzle is responsible for introducing gas into the electric arc area to form a high-temperature and high-speed plasma flow, thereby realizing the cutting of metal materials;

[0072] The deflection joint 333 is fixedly connected with the outer surface of the cutting torch nozzle 331 in the bottom end, and the vertical traction rod 334 is fixedly connected with the top end of the deflection joint 333, and the rollers with motors in the deflection joint 333 can control the deflection of the cutting torch nozzle 331, so that the cutting torch nozzle 331 can perform vertical cutting and lateral cutting work;

[0073] The built-in sliding block 335 is slidably connected with the axial center of the inner wall of the gantry 31 in the outer surface;

[0074] The outer surface of the gas thrust device 337 is sleeved with a traction connecting pipe 336, one end of the traction connecting pipe 336 away from the gas thrust device 337 is fixedly connected with the outer surface of the built-in sliding block 335, and the gas thrust device 337 changes the length of the traction connecting pipe 336 by controlling the pressure in the traction connecting pipe 336, thereby achieving the effect of traction of the built-in sliding block 335.

[0075] The gantry 31 comprises,

[0076] The guide shell 311 is provided with a storage area symmetrically arranged on both sides of the inner wall of the guide shell 311.

[0077] The supply box 312 is provided in the interior of the guide shell 311 through the storage area, and the number of the supply box 312 is two; the bottom of the inner cavity of the supply box 312 is provided with a sealing sliding plate 313 through a guide sliding groove, and different gases are respectively added to the inner sides of the two supply boxes 312 to supply the cutting torch nozzle 331.

[0078] The pressurizing connector 314 is extended to the interior of the supply box 312 through the sealing sliding plate 313, and the bottom end of the pressurizing connector 314 is butted with the top end of the drainage pipe 332; the pressurizing connector 314 pressurizes the fuel in the supply box 312 into the cutting torch nozzle 331.

[0079] After the processed steel material 2 is placed on the upper part of the transfer component 1, the transfer component 1 transports the processed steel material 2 from the rear to the front, and when the front end of the processed steel material 2 is transported to the middle area of the transfer component 1, the transfer component 1 stops the transfer work, and the middle cutting component 3 cuts the side of the processed steel material 2.

[0080] The two gas thrust devices 337 push the built-in sliding block 335 to the direction close to the processed steel material 2 through the traction connecting pipe 336, the vertical traction rod 334 at the bottom adjusts the height of the cutting torch nozzle 331, the deflection joint 333 screws the cutting torch nozzle 331, the nozzle part of the cutting torch nozzle 331 is opposite to the part of the processed steel material 2 which needs to be drilled, the calibration work is completed, and then the two cutting torch nozzles 331 simultaneously perform ion cutting work on the side of the processed steel material 2, and the processed steel material 2 is expanded.

[0081] When the jet angle of the cutting torch jet head 331 is adjusted, the middle vertical push cylinder 321 pushes the air suction cylinder 322 vertically downward, and then the air suction cylinder 322 drives the horizontal connecting pipe 323 and the expanded outer cylinder 324 to slide downward, extending into the inner side area of the processed steel material 2, so that the expanded outer cylinder 324 faces the cutting torch jet head 331 through the inner wall of the processed steel material 2. When the cutting torch jet head 331 performs flaring work, the flame penetrating the flaring of the processed steel material 2 will be sprayed into the inside of the expanded outer cylinder 324. In this process, the air suction cylinder 322 suctions air in the inside of the horizontal connecting pipe 323, so that the drainage inner pipe 326 slides to the side close to the air suction cylinder 322. Under the drainage effect of the air suction cylinder 322, the sprayed flame and sparks will be directly drained into the inside of the horizontal connecting pipe 323, and then the penetrating flame will be completely absorbed, preventing the flame from directly acting on the inner wall of the processed steel material 2. When the air suction cylinder 322 needs to be cooled after working for a period of time, the suction work is stopped, and the rebounding drainage inner pipe 326 will completely block the built-in partition plate 325. Only the penetrating flame sprayed by the cutting torch jet head 331 is covered by the shielding effect of the expanded outer cylinder 324. Since the two ends of the horizontal connecting pipe 323 are isolated from the outside under the action of the built-in partition plate 325, it is difficult for the horizontal connecting pipe 323 to conduct heat.

[0082] Before use, calibration work needs to be performed. After the cutting torch jet head 331 and the horizontal connecting pipe 323 are lowered to the specified height, the rotating cylinders 37 on both sides drive the corresponding calibration lenses 38 to rotate, so as to sweep the side surfaces of the cutting torch jet head 331 and the horizontal connecting pipe 323 through the calibration lenses 38, so as to determine whether the centers of the cutting torch jet head 331 and the horizontal connecting pipe 323 are on the same axis, so as to ensure that the flame sprayed by the cutting torch jet head 331 can be completely received by the expanded outer cylinder 324.

[0083] Embodiment 2, please refer to Figures 1-8 The present application provides a technical solution: on the basis of embodiment 1, the transfer component 1 comprises,

[0085] The vertical shelf plate 12 is symmetrically arranged on the upper surface of the bundle bottom plate 11, and the top of the inner cavity of the vertical shelf plate 12 is provided with an adaptive clamping groove.

[0086] The transfer component 1 further comprises,

[0087] The transmission roller shaft 13 is symmetrically provided with a synchronous motor 14 at both ends, and the outer surface of the synchronous motor 14 is fixedly connected with the inner cavity of the vertical shelf plate 12 through the adaptive clamping groove.

[0088] The suction component 4 is arranged in the middle of the upper surface of the gathering base plate 11, and is used to prevent sparks generated by cutting from splashing outward. The transmission roller shafts 13 are uniformly arranged on the top of the vertical support plates 12, but a group of vertical support plates 12 in the middle region of the gathering base plate 11 is replaced by the suction component 4. Since the transmission roller shafts 13 are arranged closely, the missing of a group of transmission roller shafts 13 will not affect the conveying work of the processed steel material 2.

[0089] The suction component 4 comprises,

[0090] The gathering suction cylinder 41 is fixedly connected to the middle of the upper surface of the gathering base plate 11 at the bottom end, and the two sides of the air inlet of the gathering suction cylinder 41 are symmetrically provided with the bent connecting pipe 42.

[0091] The height-adjusting push cylinder 44 is slidably connected with the vertical push rod at the axis of the inner cavity of the height-adjusting push cylinder 44.

The arc-shaped filter plate 43 is a hollow arc-shaped shell, and the recessed part for attracting gas is provided with a mesh groove for filtering residues. The gathering suction cylinder 41 is in communication with the inside of the arc-shaped filter plate 43 through the bent connecting pipe 42, and the arc-shaped filter plate 43 is given suction force.

[0093] When the torch nozzle 331 performs deflection and movement actions, it always receives fuel gas in the inside of the supply box 312 through the two side flow guide pipes 332. The pressurizing connector 314 can slide with the movement of the torch nozzle 331 through the closed sliding plate 313, and then pressurize the fuel gas in the inside of the torch nozzle 331 through the inside pump body to realize energy supply.

[0094] When the processed steel material 2 is transported to the middle region and is about to be cut and flared, the corresponding arc-shaped filter plates 43 are vertically raised by the two side height-adjusting push cylinders 44, so that the arc-shaped filter plates 43 slide from bottom to top along the side surface of the processed steel material 2. When the arc-shaped filter plates 43 are about to approach the torch nozzle 331, the raising of the arc-shaped filter plates 43 is stopped. Then, when the torch nozzle 331 works, the arc-shaped filter plates 43 will adsorb sparks and residues generated by cutting the outside of the processed steel material 2 by the torch nozzle 331 to the outer surface of the arc-shaped filter plates 43 under the suction force of the gathering suction cylinder 41, so as to greatly reduce the total amount of splashing sparks.
