Technical Field

[0001] The utility model relates to the technical field of laser tube cutting machines, in particular to a slag removal device for laser tube cutting machines. Background Art

[0002] During the laser cutting process of small-diameter thin-walled pipes, due to the small diameter, the high-temperature cutting slag after cutting will burn the inner wall of the opposite pipe under the action of high-pressure gas; after cutting, the high-temperature cutting slag is sprayed onto the inner wall of the pipe, and some of the cutting slag adheres to the inner wall of the pipe and cannot be cleaned.

This method has limited effect, and the head of the slag receiving rod is easily damaged due to long-term contact with high temperature.

[0046] In order to better explain the utility model and facilitate understanding, the utility model is described in detail below with reference to the accompanying drawings and through specific implementation methods. Figure 4 The orientation is used as a reference.

[0047] Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0048] like Figure 1-4As shown, the utility model provides a slag removal device for a laser tube cutting machine, which includes a slag receiving mechanism 7 and a circulation mechanism. Among them, a slag receiving chamber is provided on the slag receiving mechanism 7, which is used for high-temperature cutting slag ejected under the action of high-pressure gas during cutting, so as to prevent the high-temperature cutting slag from being ejected onto the inner wall of the pipe and burning the inner wall of the pipe or adhering to the inner wall of the pipe. The slag receiving chamber on the slag receiving mechanism 7 can move along the axial direction of the pipe to be cut, and the slag receiving chamber reaches the bottom of the laser cutting head through axial movement. The opening of the slag receiving chamber is directly opposite to the cutting point, so as to ensure that the high-temperature cutting slag can be accurately ejected into the slag receiving chamber. The circulation mechanism is connected to the slag receiving chamber through a pipeline circulation, and the circulation mechanism and the connecting pipeline are filled with a coolant 140, which can be conventional water, inorganic salt solution, etc. The circulation mechanism is used to drive the coolant to circulate in the connecting pipeline and the slag receiving chamber, and is preferably a circulation pump. The splash generated during cutting will fuse with the coolant 140, and the high-temperature splash will be cooled by the fusion adsorption of the coolant 140. The coolant 140 in the circulation mechanism is pressurized by the circulation mechanism and injected into the slag receiving chamber. The waste slag and smoke generated in the cutting process are adsorbed and extracted from the slag receiving chamber by the high-pressure coolant 140. The slag receiving chamber is continuously flushed by the high-pressure coolant 140, which has a cooling effect on the slag receiving mechanism 7, thereby avoiding the occurrence of burns, adhesions, and fumigation of the slag receiving mechanism 7 and the slag receiving chamber, thereby improving the service life.

[0049] like Figure 1 As shown, the slag removal device of the laser tube cutting machine also includes a filtering mechanism, and the filtering mechanism, the circulation mechanism and the slag receiving chamber are circulated and connected in sequence through a pipeline. The slag-liquid mixture refluxed from the slag receiving chamber is precipitated and filtered by the filtering mechanism and then transported to the slag receiving chamber by the circulation mechanism for recycling, thereby reducing the waste of resources.

[0050] Furthermore, if Figure 2As shown, the filtering mechanism includes a sedimentation component 14 and a filtering component 15. The sedimentation component 14, the filtering component 15, the circulation mechanism and the slag receiving chamber are circulated and connected in sequence through a pipeline. The slag-liquid mixture is filtered by the filtering component 15 after precipitation to remove non-suspended slag materials, and the solid particles in the coolant 140 are removed. The filtering component 15 is preferably a paper belt filtering device, and the circulation mechanism can use a high-pressure infusion pump. Specifically, the sedimentation component 14 includes a sedimentation box and an overflow box. The sedimentation box and the overflow box are both sealed boxes that can be opened, and the bottom of the overflow box is connected to the bottom of the sedimentation box. Or the sedimentation box and the overflow box are an integrated structure, the sedimentation and overflow parts are separated by a partition 144, the bottom is connected, and a sealing cover 142 is detachably arranged at the top opening of the sedimentation part of the box to facilitate slag removal. The overflow box is provided with an overflow port 145, which is connected to the filter assembly 15. When the liquid level in the overflow box is higher than the overflow port 145, the coolant 140 will overflow into the filter assembly 15 below through the overflow port 145. The coolant 140 filtered by the filter assembly 15 is pumped into the slag receiving chamber again by the circulation structure, thus realizing the circulation and filtration of water. The sedimentation box is provided with a feed pipe 141, the inlet of the feed pipe 141 is connected to the slag receiving chamber, and the level of the outlet of the feed pipe 141 is lower than the level of the overflow port 145, so that the outlet of the feed port is immersed in the coolant 140, and the slag-liquid mixture recovered from the slag receiving chamber directly passes through the coolant 140 to avoid liquid splashing.

[0051] like Figure 3 As shown, the filtering mechanism also includes an exhaust component 13, and an exhaust port 143 is provided on the top surface of the sedimentation box. The inlet of the exhaust component 13 is connected to the exhaust port 143 on the sedimentation box, and the horizontal height of the inlet of the exhaust component 13 is higher than the horizontal height of the overflow port 145. The exhaust component 13 is preferably a high-pressure fan, and the air in the sedimentation box is extracted by the exhaust component 13, so that the sedimentation box is in a negative pressure state, so that the air flow can enter the sedimentation box through the feed pipe 141, and the exhaust component 13 assists in extracting the slag-liquid mixture in the slag receiving chamber into the sedimentation box, increasing the flow rate of the reflux, and preventing the slag from clogging the slag receiving mechanism 7 and the corresponding pipelines. At the same time, the smoke generated during the laser cutting process is extracted by the exhaust component 13, and the smoke is directly input into the coolant 140, and the dust in the smoke is adsorbed by the coolant 140.

[0052] like Figure 1 and Figure 4 As shown, the slag removal device of the laser tube cutting machine also includes a mounting frame 1, a first driving mechanism and a stripping mechanism. The first driving mechanism is arranged on the mounting frame 1, and the slag receiving mechanism 7 is arranged on the first driving mechanism. The slag receiving mechanism is preferably a rod-shaped structure, the first end of which is connected to the first driving mechanism, and the second end is provided with a slag receiving cavity. The first driving mechanism is used to drive the slag receiving mechanism to move along the axial direction of the tube to be cut, so as to Figure 4The orientation is used as a reference, that is, the first driving mechanism drives the slag receiving mechanism to move in the horizontal direction, so that the slag receiving cavity on the slag receiving mechanism 7 can be accurately transported to the position directly below the laser cutting point. The stripping mechanism is slidably arranged on the mounting frame, and the slag receiving mechanism is slidably connected with the stripping mechanism. When the stripping mechanism moves horizontally relative to the slag receiving mechanism, the pipe dropped on the slag receiving mechanism can be pushed off.

[0053] Further, the first driving mechanism includes a first pallet assembly 3 and a first cylinder 81, the cylinder body of the first cylinder 81 is arranged on the mounting frame 1, the first pallet assembly 3 is slidably connected to the mounting frame 1, the piston rod of the first cylinder 81 is connected to the first pallet assembly 3, and the first pallet assembly 3 is driven to slide horizontally by the first cylinder 81. The first driving mechanism also includes a second cylinder 82, the cylinder body of the second cylinder 82 is arranged on the first pallet assembly 3, the piston rod of the first cylinder 81 and the piston rod of the second cylinder 82 are arranged oppositely, and the piston rod of the second cylinder 82 is connected to the piston rod of the first cylinder 81, so as to increase and control the stroke of the horizontal movement of the first pallet assembly 3.

The second driving mechanism is installed on the first support plate assembly 3, and the slag receiving mechanism 7 is installed on the second driving mechanism. The slag receiving mechanism 7 is driven by the second driving mechanism to move radially along the tube to be cut, that is, the slag receiving mechanism 7 moves in the vertical direction. The first cylinder 81 drives the slag receiving chamber to move horizontally to below the laser cutting point, and the second driving mechanism drives the slag receiving chamber to rise to the best position for slag receiving, that is, the slag receiving chamber is as close to the laser cutting point as possible under the premise that the slag receiving mechanism 7 does not contact the tube, to ensure that the high-temperature cutting slag can be accurately sprayed into the slag receiving chamber.

[0055] See also Figure 1 and Figure 4The stripping mechanism includes a second pallet assembly 4 and a third cylinder 61. The second pallet assembly 4 is slidably disposed on the mounting frame 1.

The piston rod of the third cylinder 61 is connected to the second pallet assembly 4 to drive the second pallet assembly 4 to move horizontally. The slag connection mechanism 7 is slidably connected to the second pallet assembly. The second pallet assembly 4 is used to install the slag connection mechanism 7 and can move horizontally relative to the slag connection mechanism 7. Since the slag connection mechanism 7 extends into the interior of the pipe, the cut pipe will be sleeved on the slag connection mechanism 7. At this time, the third cylinder 61 is actuated to drive the second pallet assembly 4 to move horizontally. A material blocking plate is disposed on the second pallet assembly 4, and the pipe is pushed backward by the material blocking plate until the pipe is completely separated from the slag connection mechanism 7. The stripping mechanism also includes a fourth cylinder 62, the cylinder body of the fourth cylinder 62 is arranged on the second support plate assembly 4, the piston rod of the fourth cylinder 62 is arranged opposite to the piston rod of the third cylinder 61, and the piston rod of the fourth cylinder 62 is connected to the piston rod of the third cylinder 61, thereby increasing and controlling the horizontal movement stroke of the second support plate assembly 4.

[0056] See also Figure 4 Matching with the second driving mechanism, the slag removal device of the laser tube cutting machine also includes a third driving mechanism 5, which is arranged on the second support plate assembly 4 and moves horizontally with the third driving mechanism 5 through the second support plate assembly 4. The slag receiving mechanism 7 is connected to the third driving mechanism 5, and the third driving mechanism 5 can be a cylinder or a screw assembly, etc. The third driving mechanism 5 drives the slag receiving mechanism 7 to move in the vertical direction through the third driving mechanism 5. The third driving mechanism 5 and the second driving mechanism act synchronously to jointly drive the slag receiving mechanism 7 to move in the vertical direction.

[0057] In a specific embodiment, when the slag connection mechanism is a slag connection rod, a guide sleeve seat is fixed on the third driving mechanism on the second support plate assembly 4, the slag connection rod is slidably connected with the guide sleeve, and the guide sleeve seat guides the slag connection rod. A connecting seat is fixed on the second driving mechanism on the first support plate assembly 3, and the connecting seat is connected to the slag connection rod through a quick-release clamp.

The first pallet assembly 3 and the second pallet assembly 4 both include a fixed plate and a flip plate connected by a rotating shaft. When slag-free cutting is not required, the flip plate is lifted and the slag receiving mechanism 7 is removed without affecting its cutting. The first pallet assembly 3 and the second pallet assembly 4 are respectively installed with a second drive mechanism and a third drive mechanism 5, which can drive the slag receiving mechanism 7 to move vertically as required. In addition, it should be noted that, in addition to the cylinder, the use of a drive structure such as a lead screw or a gear rack instead of a cylinder is within the protection scope of the present utility model.
