Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, and in particular, to a linkage type dust extraction structure. Background Art

[0002] The application of laser cutting machines has developed rapidly in the domestic market in recent years, especially in the field of sheet metal cutting and processing. It has the advantages of high cutting accuracy, fast cutting speed, adaptability to various complex graphics, automatic typesetting, smooth incision, low processing cost, etc. It has replaced punching machines, flame cutting, plasma cutting and other equipment.

[0003] With the continuous updating of laser cutting technology, the demand for high-power laser cutting machines is increasing. Among them, the use of ground-track laser cutting machines is very extensive, which has brought great convenience to industrial production. The high-temperature molten iron filings generated by the cutting mechanism during the cutting process fall on the bed or the serrated support plate. This will cause the bed and the serrated support plate to deform over a long period of time. The serrated support plate can be replaced regularly as a consumable, but the bed as an integral component is expensive and is welded and fixed, so it cannot be replaced regularly. After long-term use, the bed of a large-format ground-track laser cutting machine may be deformed, affecting the laser cutting efficiency.

[0004] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable linkage dust extraction structure for large-format ground-rail laser cutting machines. Utility Model Content

[0005] The purpose of the utility model is to provide a linkage dust extraction structure with a simple structure. Air blowing and air suction structures are directly arranged at both ends of a beam for placing a laser cutting head. The dust extraction structure moves with the beam.

[0026] Technologies, methods, and systems known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and systems should be considered part of the authorization specification.

[0027] Embodiment 1: Figures 1 to 3 The figure is only one of the embodiments of the present invention, a linkage dust extraction structure, including a beam 1 arranged on a bed 4, a blower 2 arranged at one end of the beam 1, and a suction bin 3 arranged on a side of the beam 1 away from the blower 2; the bed 4 includes a side plate 41 for connecting with the beam 1, a dust suction duct 42 is arranged on the side plate 41, and the dust suction duct 42 is connected to the suction bin 3.

[0028] In the present invention, the bed 4 is the bed of a large-format ground-rail laser cutting machine. A grid structure is provided on the bed for placing the cutting plate. The dust extraction structure is actually the cutting structure, which is used to cut the plate. The dust extraction structure and the cutting structure are fixed and move with the bed. The crossbeam 1 is provided on the bed 4, and the laser head for cutting the plate is provided on the crossbeam 1. Both ends of the crossbeam 1 are mounted on the side plates 41 of the bed 4 for sliding. A blower 2 is provided at one end of the crossbeam 1, and a suction bin 3 is provided at the other end, so that the laser head is always located between the blower 2 and the suction bin 3. When the laser head cuts the plate, the cutting point is also located between the blower 2 and the suction bin 3. The blower 2 blows the high-temperature smoke generated by the cutting toward the direction of the suction bin 3, and then the smoke is sucked and discharged at the suction bin 3, effectively avoiding deformation of the bed 4 caused by the high-temperature smoke.

[0029] In this way, the blower 2 and the suction bin 3 both move with the crossbeam 1. When the cutting head moves to any place for cutting, the blower and the suction bin will follow and link to the cutting place to discharge the high-temperature smoke and dust generated at the cutting place, effectively preventing the high-temperature smoke and dust from causing deformation of the bed 4.

[0030] Of course, the height of the blower 2 and the suction bin 3 are both lower than the height of the beam 1. In fact, the height of the blower 2 and the suction bin 3 are the same as the grid structure. To be precise, the lower ends of the blower 2 and the suction bin 3 are slightly lower than the upper surface of the grid structure, and the upper ends of the blower 2 and the suction bin 3 are higher than the upper surface of the cutting plate on the grid structure, so that when the cutting plate on the grid structure is cut, the blower 2 and the suction bin 3 can effectively blow and suck the cutting smoke.

[0031] In addition, a dust suction duct 42 is provided on the side panel 41 and is arranged along the extension direction of the bed 4. The dust suction duct 42 is connected with the air suction bin 3. A suction fan is arranged in the dust suction duct 42. The air suction bin 3 moves along with the cross beam 1, and the dust suction channel 42 is connected with the air suction bin 3. In fact, the air suction bin 3 has the dust suction ability because it is connected with the dust suction channel 42.

[0032] In order to ensure the stability of the air suction capacity of the air suction bin 3, an opening for connecting with the air suction bin 3 is provided on the upper side of the dust suction duct 42, and a three-proof cloth is provided at the opening. Both ends of the three-proof cloth 421 are connected with the air suction bin 3. In fact, after one end of the three-proof cloth is connected to the front end of the air suction bin 3, the other end of the three-proof cloth bypasses the front end of the dust suction duct 42 to reach the lower side of the dust suction channel 42, and then goes up from the other end of the dust suction channel 42, and finally connects with the rear end of the air suction bin 3, so that when the air suction bin 3 moves following the crossbeam 1, the three-proof cloth also moves and transmits following the air suction bin 3, ensuring that the dust suction duct 42 is connected to the air suction bin 3 only on the upper side, thereby improving the sealing of dust extraction and ensuring the stable air suction of the air suction bin 3.

[0033] Embodiment 2, still as Figures 1 to 3 The figure shown is only one of the embodiments of the present invention. On the basis of the first embodiment, in a linkage dust extraction structure of the present invention, the side panel 41 includes a first side panel 411 arranged on the side of the beam 1 close to the blower 2 and a second side panel 412 arranged on the side of the beam 1 close to the suction bin 3. The dust suction duct 42 is arranged on the side of the second side panel 412 close to the first side panel 411. The blower 2 is arranged on the side of the first side panel 411 close to the second side panel 412. The upper end of the blower 2 is provided with a limiting strap 21 for connecting with the upper side of the first side panel 411.

[0034] In the present invention, guide rails 43 are provided on the side panels 41 to facilitate the sliding of the cross beam 1 , and the lower sides of both ends of the cross beam 1 are connected to the upper guide rails 43 of the first side panel 411 and the second side panel 412 , respectively.

[0035] Here, the beam 1 is provided with a driving motor for driving the displacement of the beam 1 and a controller electrically connected to the driving motor. The blower 2 and the suction bin 3 are electrically connected to the controller. Only when the beam 1 is displaced, the blower 2 and the suction bin 3 are started to discharge smoke and dust.

[0036] Of course, there are two driving motors, one at each end of the crossbeam 1 to synchronously drive the crossbeam 1 to move.

[0037] Finally, the number of the bed frames 4 is at least two, that is, the large-format ground-rail laser cutting machine is composed of multiple bed frames. At this time, a linkage dust extraction structure is adopted, which can be used for cutting machine beds with various travels.

[0038] The utility model discloses a linkage dust extraction structure with a simple structure. Air blowing and air suction structures are directly arranged at both ends of a beam for placing a laser cutting head. The dust extraction structure moves with the beam. When the cutting head is moved to any place for cutting, the blower and the air suction bin will follow and be linked to the cutting place to extract the high-temperature smoke and dust generated at the cutting place, thereby effectively avoiding deformation and damage of the bed body. The utility model can be applicable to laser cutting machines of various specifications.

[0039] The present invention is not limited to the above specific implementation modes, and the present invention can have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made to the above implementation modes based on the technical essence of the present invention shall be included in the protection scope of the present invention.
