Description

Technical Field

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

[0002] Plasma cutting is a processing method that uses the heat of a high-temperature plasma arc to partially melt and evaporate the metal at the workpiece cut, and uses the momentum of high-speed plasma to remove the molten metal to form a cut. Plasma cutting machines can cut various metals that are difficult to cut with oxygen cutting, especially for non-ferrous metals.

[0003] H-beam is an essential steel material for construction. After processing, it is necessary to use a plasma cutting machine to cut and expand the holes on its side to ensure that the H-beam can be effectively connected to the other components through fastening bolts. When arc cutting is performed on the side of the H-beam, in order to ensure that the expanded holes of the H-beam are completely penetrated, continuous cutting is required, which will cause the cutting machine to perform unnecessary thermal cutting on the horizontal surface and adjacent sides of the H-beam through the penetrating holes, resulting in obvious black marks on the surface of the H-beam, and the sparks sprayed from the side are prone to cause production accidents, so improvements are needed. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention solves the technical problems by adopting a technical solution: a plasma cutting machine, comprising:

[0005] Processing steel, the shape is I-shaped;

[0006] Transfer parts, used to transfer steel smoothly from back to front;

[0007] A cutting component is arranged in the middle of the transfer component and is used for expanding and cutting the side of the steel material;

[0008] The cutting component comprises:

[0009] A gantry, wherein a receiving component is disposed in the middle of the gantry, and side welding components are symmetrically disposed on both sides of the gantry;

[0010] The receiving component comprises:

[0011] A vertical push cylinder, the top of which is fixedly connected to the middle of the gantry;

[0012] The suction cylinder, the bottom end of the vertical push cylinder is plugged into the upper surface of the suction cylinder through a push rod, the bottom rod of the vertical push cylinder can drive the suction cylinder to slide up and down, and the rubber sleeve sleeved on the outer surface of the bottom rod plays a role of limiting protection;

[0013] Horizontal connecting pipe, the bottom end of the air intake of the air suction cylinder is fixedly connected to the middle part of the inner cavity of the horizontal connecting pipe, and expansion outer cylinders are symmetrically arranged on both sides of the outer surface of the horizontal connecting pipe. After pre-adjustment, the two expansion outer cylinders can adapt to the distance between the two sides of the I-shaped steel. Without fitting the I-shaped steel, they can maintain a relatively close distance from the inner wall of the I-shaped steel;

[0014] Built-in partition, the built-in partition is arranged on the inner wall of the horizontal connecting pipe, and a drainage inner pipe is slidably connected to the axis of the inner cavity of the built-in partition. The drainage inner pipe is provided with a cutting groove, and a spring is sleeved on the end part connected to the built-in partition. When the air suction cylinder sucks air, the drainage inner pipe slides towards the side close to the air suction cylinder under the action of air pressure, and communicates with the outside and the air suction cylinder through its cutting groove. After the air suction cylinder finishes working, under the elastic force of the spring, the drainage inner pipe resets, and at this time its cutting groove does not cross the built-in partition, and the drainage inner pipe blocks the built-in partition.

[0015] Further, the cutting component further includes,

[0016] Elevating frame, the number of the elevating frames is two, and the top of the elevating frame is fixedly connected to the side surface of the gantry, and the bottom of the elevating frame is fixedly connected to the ground;

[0017] Push rod plate, the outer surface of the push rod plate is fixedly connected to the inner cavity of the elevating frame, and a side push sliding rod is slidably connected to the inner cavity of the push rod plate;

[0018] Rotating cylinder, arranged at one end of the side push sliding rod away from the elevating frame, and the rotating rod at its axis can rotate around the outer shell under the action of the internal roller;

[0019] Calibration lens, the bottom end of the calibration lens is fixedly connected to the inner cavity of the rotating cylinder. The rotating cylinder drives the calibration lens to rotate around its axis through the rotating rod at its axis, so that the calibration lens can scan the drainage inner pipe and the side welding component. When the axes of the three are collinear, it means complete calibration.

[0020] Further, the side welding component includes,

[0021] Torch nozzle, drainage pipes are symmetrically arranged on both sides of the inner cavity of the torch nozzle. The inside of the torch nozzle contains key components such as an electrode and a nozzle. During the cutting process, the electrode generates an electric arc, and the nozzle is responsible for introducing gas into the arc area to form a high-temperature and high-speed plasma stream, thereby realizing the cutting of metal materials;

[0022] Deflection joint, the bottom end of the deflection joint is fixedly connected to the outer surface of the torch nozzle, the top end of the deflection joint is fixedly connected with a vertical traction rod, and the roller with a motor inside the deflection joint can control the torch nozzle to deflect, so that the torch nozzle can perform vertical cutting and lateral cutting operations;

[0023] Built-in slider, the outer surface of the built-in slider is slidably connected to the axis of the inner wall of the gantry;

[0024] Gas thruster, the outer surface of the AC port of the gas thruster is sleeved with a traction connecting pipe, one end of the traction connecting pipe away from the gas thruster is fixedly connected to the outer surface of the built-in slider, and the gas thruster changes the long end of the traction connecting pipe by controlling the pressure inside the traction connecting pipe, so as to achieve the effect of pulling the built-in slider to move.

[0025] Furthermore, the gantry includes,

[0026] Guiding housing, on both sides of the inner wall of the guiding housing, storage areas are symmetrically opened;

[0027] Supply boxes, the number of the supply boxes is two, and the outer surfaces of the supply boxes are arranged inside the guiding housing through the storage areas. At the bottom of the inner cavity of the supply box, a closed sliding plate is arranged through a guiding chute. Different gases are respectively added to the inner parts of the two supply boxes to supply materials to the cutting torch nozzle;

[0028] Pressurizing joint, the top end of the pressurizing joint extends into the supply box through the closed sliding plate, and the bottom end of the pressurizing joint is docked with the top end of the drainage pipe. The pressurizing joint pressurizes the fuel inside the supply box into the cutting torch nozzle.

[0029] Furthermore, the transfer component includes,

[0030] Bundle bottom plate, the bundle bottom plate is arranged on the ground;

[0031] Vertical rack plates, the vertical rack plates are symmetrically arranged on the upper surface of the bundle bottom plate, and at the top of the inner cavity of the vertical rack plates, an adaptor slot is opened.

[0032] Furthermore, the transfer component also includes,

[0033] Drive roller shafts, at both ends of the drive roller shafts, synchronous motors are symmetrically arranged, and the outer surfaces of the synchronous motors are fixedly connected to the inner cavity of the vertical rack plates through the adaptor slots;

[0034] Attracting component, arranged in the middle of the upper surface of the bundle bottom plate, used to prevent the sparks generated by cutting from splashing outwards. The drive roller shafts are evenly arranged on the top of the vertical rack plates, but a group of vertical rack plates in the middle area of the bundle bottom plate is replaced by the attracting component. Since the drive roller shafts are arranged relatively closely, the absence of a group of drive roller shafts will not affect the transfer work of the processed steel.

[0035] Furthermore, the attracting component includes,

[0036] Bundle suction cylinder, the bottom end of the bundle suction cylinder is fixedly connected to the middle of the upper surface of the bundle bottom plate, and on both sides of the air inlet of the bundle suction cylinder, bent connecting pipes are symmetrically arranged;

[0037] A height-adjusting push cylinder, wherein a vertical push rod is slidably connected to the axis of the inner cavity of the height-adjusting push cylinder;

[0038] An arc-shaped filter plate, wherein the bottom of the inner cavity of the arc-shaped filter plate is fixedly connected to the top of the bent connecting tube, and the bottom of the outer surface of the arc-shaped filter plate is fixedly connected to the top of the vertical push rod. The arc-shaped filter plate is a hollow arc-shaped shell, and a mesh groove for filtering residues is provided in the concave part responsible for attracting gas. The clustering suction cylinder is connected to the interior of the arc-shaped filter plate through the bent connecting tube, thereby giving suction to the arc-shaped filter plate.

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

[0040] 1. The device uses the cutting torch nozzles on both sides to cut and expand the sides of the processed steel. When the cutting torch nozzles continue to apply high-temperature heat energy, unnecessary heat energy cutting will be performed on the transverse surface and adjacent sides of the processed steel through the holes that have not been completely penetrated, resulting in obvious black marks on the surface of the processed steel, and the sparks sprayed from the side are likely to cause production accidents. Therefore, a receiving component that docks with the cutting torch nozzle is set in the middle area of the processed steel to prevent the flame of the cutting torch nozzle from penetrating the processed steel and the sparks from splashing to the inner area of the processed steel, thereby protecting the inner area of the processed steel from the high-temperature flame of the cutting torch nozzle and avoiding the above-mentioned problems.

[0041] 2. Since the suction cylinder can make the expansion outer cylinders on both sides have a certain adsorption capacity through suction, the flame and sparks penetrating from the cutting torch nozzle will be drained into the inside of the expansion outer cylinder, so that the expansion outer cylinder can play an effective adsorption effect without close contact with the processed steel, thereby ensuring that the processed steel can be smoothly transported without friction with the side of the expansion outer cylinder, resulting in the problem of wear of the expansion outer cylinder. After the cutting torch nozzle is processed, the adsorption effect of the drainage tube can drive the external air to quickly cool the expanded mouth of the processed steel, preventing the problem of workers being scalded by high temperature when checking the expanded mouth of the processed steel.

[0042] 3. When the vacuum tube needs to be cooled after working for a period of time, the suction work will be stopped. At this time, the rebounding drainage inner tube will completely block the built-in partition, and only rely on the shielding effect of the expanded outer tube to cover the penetrating flame ejected from the cutting torch nozzle. Since the two ends of the horizontal connecting tube are isolated from the outside by the action of the built-in partition, it is difficult for the inside of the horizontal connecting tube to conduct heat, preventing the vacuum tube from overheating and damage due to long-term continuous absorption work.

[0043] 4. When the processed steel is transported to the central area and is about to undergo cutting and flaring operations, and then when the cutting torch nozzle is working, under the suction force of the cluster suction cylinder, the arc-shaped filter plate adsorbs the sparks and residues generated by the cutting spatter on the outer side of the processed steel by the cutting torch nozzle to the outer surface of the arc-shaped filter plate, thereby greatly reducing the total amount of splashed sparks and avoiding production accidents caused by externally splashed sparks. At the same time, the arc-shaped filter plate can adsorb the toxic gases generated by cutting into the interior of the cluster suction cylinder, preventing the toxic gases from spreading to the production workshop and causing damage to the health of personnel, thus playing the function of safe production.

[0053] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations will be obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles of the present invention and its practical applications, and to enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0054] Example 1. Refer to Figures 1-6 , the present invention provides a technical solution: a plasma cutting machine, comprising:

[0055] The processed steel 2 is in the shape of an I-beam;

[0056] The transfer component 1 is used to smoothly transfer the steel from back to front;

[0057] The cutting component 3 is arranged in the middle of the transfer component 1 and is used for reaming and cutting the side surface of the steel;

[0058] The cutting component 3 includes:

[0059] The gantry 31, a receiving component 32 is arranged in the middle of the gantry 31, and side welding components 33 are symmetrically arranged on both sides inside the gantry 31;

[0060] The receiving component 32 includes:

[0061] The vertical push cylinder 321, the top of the vertical push cylinder 321 is fixedly connected to the middle of the gantry 31;

[0062] The suction cylinder 322, the bottom end of the vertical push cylinder 321 is inserted into the upper surface of the suction cylinder 322 through a push rod, and the bottom rod of the vertical push cylinder 321 can drive the suction cylinder 322 to slide up and down, and the rubber sleeve sleeved on the outer surface of the bottom rod plays a role of limiting and protecting;

[0063] The horizontal connecting pipe 323, the bottom end of the air inlet of the suction cylinder 322 is fixedly connected to the middle of the inner cavity of the horizontal connecting pipe 323, and expansion outer cylinders 324 are symmetrically arranged on both sides of the outer surface of the horizontal connecting pipe 323. The two expansion outer cylinders 324 can be pre-adjusted to adapt to the distance between the two sides of the I-shaped steel. Without fitting the I-shaped steel, they are kept at a relatively close distance from the inner wall of the I-shaped steel;

[0064] The built-in partition 325 is arranged on the inner wall of the transverse connecting pipe 323. At the axis of the inner cavity of the built-in partition 325, a drainage inner pipe 326 is slidably connected. The drainage inner pipe 326 is provided with a cutting groove, and a spring is sleeved on the end part connected to the built-in partition 325. When the air suction cylinder 322 pumps air, the drainage inner pipe 326 slides towards the side close to the air suction cylinder 322 under the action of air pressure, and communicates with the outside and the air suction cylinder 322 through its cutting groove. After the operation of the air suction cylinder 322 ends, under the elastic force of the spring, the drainage inner pipe 326 resets, and at this time its cutting groove does not cross the built-in partition 325, and the drainage inner pipe 326 blocks the built-in partition 325.

[0065] The cutting component 3 further includes

[0066] The lifting frame 34, the number of the lifting frames 34 is two, and the top of the lifting frame 34 is fixedly connected to the side surface of the gantry 31, and the bottom of the lifting frame 34 is fixedly connected to the ground;

[0067] The push rod plate 35, the outer surface of the push rod plate 35 is fixedly connected to the inner cavity of the lifting frame 34, and a side push sliding rod 36 is slidably connected to the inner cavity of the push rod plate 35;

[0068] The rotating cylinder 37 is arranged at one end of the side push sliding rod 36 far from the lifting frame 34, and the rotating rod at its axis can rotate around the external housing under the action of the internal roller;

[0069] The calibration lens 38, the bottom end of the calibration lens 38 is fixedly connected to the inner cavity of the rotating cylinder 37. The rotating cylinder 37 drives the calibration lens 38 to rotate around its axis through the rotating rod at its axis, so that the calibration lens 38 can scan the drainage inner pipe 326 and the side welding component 33. When the axes of the three are collinear, it means complete calibration.

[0070] The side welding component 33 includes

[0071] The torch nozzle 331, drainage pipes 332 are symmetrically arranged on both sides of the inner cavity of the torch nozzle 331. The inside of the torch nozzle 331 contains key components such as electrodes and nozzles. During the cutting process, the electrode generates an electric arc, and the nozzle is responsible for introducing gas into the arc area to form a high-temperature and high-speed plasma flow, so as to realize the cutting of metal materials;

[0072] The deflection joint 333, the bottom end of the deflection joint 333 is fixedly connected to the outer surface of the torch nozzle 331, the top end of the deflection joint 333 is fixedly connected to a vertical traction rod 334, and the roller with a motor inside the deflection joint 333 can control the torch nozzle 331 to deflect, so that the torch nozzle 331 can perform vertical cutting and lateral cutting operations;

[0073] The built-in slider 335, the outer surface of the built-in slider 335 is slidably connected to the axis of the inner wall of the gantry 31;

[0074] The gas thruster 337 has a traction connecting pipe 336 sleeved on the outer surface of the AC port of the gas thruster 337. One end of the traction connecting pipe 336 away from the gas thruster 337 is fixedly connected to the outer surface of the built-in slider 335. The gas thruster 337 changes the long end of the traction connecting pipe 336 by controlling the pressure inside the traction connecting pipe 336, thereby achieving the effect of pulling the built-in slider 335 to move.

[0075] The gantry 31 includes

[0076] A guiding housing 311 with storage areas symmetrically opened on both sides of the inner wall of the guiding housing 311;

[0077] Supply boxes 312, the number of supply boxes 312 is two, and the outer surfaces of the supply boxes 312 are arranged inside the guiding housing 311 through the storage areas. A sealing slide plate 313 is arranged at the bottom of the inner cavity of the supply box 312 through a guiding chute. Different gases are respectively added to the interiors of the two supply boxes 312 to supply materials to the cutting torch nozzle 331;

[0078] A pressure - adding joint 314, the top end of the pressure - adding joint 314 extends into the supply box 312 through the sealing slide plate 313, the bottom end of the pressure - adding joint 314 is butted against the top end of the drainage pipe 332, and the pressure - adding joint 314 pressurizes the fuel inside the supply box 312 into the cutting torch nozzle 331.

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

[0080] The gas thrusters 337 on both sides push the built - in slider 335 towards the direction close to the processed steel 2 through the traction connecting pipe 336. At the same time, the vertical traction rod 334 at the bottom adjusts the height of the cutting torch nozzle 331, and the deflection joint 333 screws the cutting torch nozzle 331 to make the nozzle part of the cutting torch nozzle 331 face the part of the processed steel 2 that needs to be drilled, completing the calibration work. Subsequently, the cutting torch nozzles 331 on both sides simultaneously perform ion cutting work on the side of the processed steel 2 to flare the processed steel 2.

[0081] When adjusting the nozzle angle of the torch nozzle 331, the vertical push cylinder 321 in the middle pushes the suction cylinder 322 vertically downward. Then, the suction cylinder 322 drives the horizontal connecting pipe 323 and the expansion outer cylinder 324 to slide down and extend into the inner area of the processed steel 2, so that the expansion outer cylinder 324 faces the torch nozzle 331 across the inner wall of the processed steel 2. When the torch nozzle 331 performs the flaring operation, the flame passing through the flare of the processed steel 2 will be sprayed into the interior of the expansion outer cylinder 324. During this process, the suction cylinder 322 sucks air inside the horizontal connecting pipe 323, causing the drainage inner pipe 326 to slide toward the side close to the suction cylinder 322. Under the drainage action of the suction cylinder 322, the sprayed flame and sparks will be directly drained into the interior of the horizontal connecting pipe 323, thereby completely absorbing this part of the passing-through flame and preventing the flame from directly acting on the inner wall of the processed steel 2. When the suction cylinder 322 needs to be cooled after working for a period of time and thus stops the suction operation, the rebounding drainage inner pipe 326 will completely block the built-in partition 325, and only rely on the shielding effect of the expansion outer cylinder 324 to cover the passing-through flame ejected by the torch nozzle 331. Since both ends of the horizontal connecting pipe 323 are isolated from the outside under the action of the built-in partition 325, it is difficult for heat to conduct inside the horizontal connecting pipe 323.

[0082] Before carrying out the use work, calibration work needs to be carried out first. After the torch nozzle 331 and the horizontal connecting pipe 323 synchronously descend to the specified height, the rotating cylinders 37 on both sides will drive the corresponding calibration lenses 38 to rotate, so as to sweep around the sides of the torch nozzle 331 and the horizontal connecting pipe 323 through the calibration lenses 38, thereby judging whether the centers of the torch nozzle 331 and the horizontal connecting pipe 323 are on the same axis, so as to ensure that the flame ejected by the torch nozzle 331 can be completely received by the expansion outer cylinder 324.

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

[0084] The bundled bottom plate 11 is arranged on the ground;

[0085] The vertical frame plates 12 are symmetrically arranged on the upper surface of the bundled bottom plate 11, and an adapter slot is opened at the top of the inner cavity of the vertical frame plate 12.

[0086] The transfer component 1 further includes,

[0087] The drive roller shafts 13 are symmetrically provided with synchronous motors 14 at both ends, and the outer surfaces of the synchronous motors 14 are fixedly connected to the inner cavity of the vertical frame plate 12 through the adapter slots;

[0088] The attracting component 4 is arranged in the middle of the upper surface of the beam bottom plate 11 and is used to prevent the sparks generated by cutting from splashing outwards. The driving roller shafts 13 are evenly mounted on the top of the vertical frame plates 12. However, a group of vertical frame plates 12 in the middle area of the beam bottom plate 11 are replaced by the attracting component 4. Since the driving roller shafts 13 are arranged relatively closely, the absence of a group of driving roller shafts 13 will not affect the transfer work of the processed steel 2.

[0089] The attracting component 4 includes

[0090] a beam suction cylinder 41. The bottom end of the beam suction cylinder 41 is fixedly connected to the middle of the upper surface of the beam bottom plate 11, and bent connecting pipes 42 are symmetrically arranged on both sides of the air inlet of the beam suction cylinder 41;

[0091] a height-adjusting push cylinder 44. A vertical push rod is slidably connected to the axis of the inner cavity of the height-adjusting push cylinder 44;

[0092] an arc-shaped filter plate 43. The bottom of the inner cavity of the arc-shaped filter plate 43 is fixedly connected to the top end of the bent connecting pipe 42, and the bottom of the outer surface of the arc-shaped filter plate 43 is fixedly connected to the top end of the vertical push rod. The arc-shaped filter plate 43 is a hollow arc-shaped shell, and a mesh groove for filtering residues is provided at the concave part responsible for attracting gas. The beam suction cylinder 41 is connected to the inside of the arc-shaped filter plate 43 through the bent connecting pipe 42, giving the arc-shaped filter plate 43 suction force.

[0093] When the cutting torch nozzle 331 makes deflection and movement actions, it always receives the fuel gas inside the supply tank 312 through the drainage pipes 332 on both sides. The pressure connection head 314 can slide with the movement of the cutting torch nozzle 331 through the closed slide plate 313, and then pressurize the fuel gas to the inside of the cutting torch nozzle 331 through the internal pump body to achieve energy supply.

[0094] When the processed steel 2 is transported to the middle area and is about to carry out cutting and flaring work, the height-adjusting push cylinders 44 on both sides vertically lift the corresponding arc-shaped filter plates 43, so that the arc-shaped filter plates 43 fit against the side of the processed steel 2 and slide upwards from bottom to top. When approaching the cutting torch nozzle 331, stop lifting the arc-shaped filter plates 43. Subsequently, when the cutting torch nozzle 331 is working, under the suction force of the beam suction cylinder 41, the arc-shaped filter plates 43 adsorb the sparks and residues generated by the cutting and splashing of the cutting torch nozzle 331 on the outer side of the processed steel 2 to the outer surface of the arc-shaped filter plates 43, thereby greatly reducing the total amount of splashed sparks.

[0095] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art and related fields based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention shall be implemented by conventional means in the art without special specification and limitation.
