Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe interchange valve technology, specifically a pipe interchange valve for laser-cut pipes and plates. Background Technology
[0002] As we all know, the laser cutting industry has developed for decades, with increasingly advanced cutting techniques, higher laser power, and increasingly stringent industry requirements. Furthermore, with rising living standards, there is a growing emphasis on operator safety. Laser cutting often involves cutting pipes and sheets, each requiring corresponding piping for ventilation and other operations. Currently, the interchangeability of piping for pipe and sheet cutting presents problems such as inconvenience in operation, cumbersome debugging, and complex structure, affecting the efficiency and safety of laser cutting operations. Therefore, a valve that allows for convenient interchangeability of piping for pipe and sheet cutting is needed to meet actual production needs. Utility Model Content
[0003] The purpose of this invention is to provide an interchangeable valve for pipes and plates used in laser cutting, in order to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a pipe interchange valve for laser-cut pipes and plates, comprising a partitioned exhaust box, one end of which is fixedly connected to two symmetrically arranged air inlets, namely, an air inlet 1 and an air inlet 2. The front and back of the partitioned exhaust box are respectively covered with a cover 1 and a cover 2. A rotating shaft is rotatably connected between the cover 1 and the cover 2. A copper sleeve is fixedly fitted onto the surface of the rotating shaft. A blade 1 and a blade 2 are fixedly fitted onto the surface of the copper sleeve. One end of the rotating shaft passes through the cover 1 and is fixed to a connecting rod. One end of the connecting rod is rotatably connected to the output end of a rotary cylinder. The end of the rotary cylinder opposite to the output end is rotatably connected to the cover 1 via a cylinder rotating shaft.
[0005] The system connects to the pipes and plates cut by the laser machine via air inlet one and air inlet two, respectively. When air inlet one needs to be open and air inlet two needs to be closed, a rotary cylinder is activated. The output end of the rotary cylinder drives the connecting rod to move, which in turn drives the rotating shaft to rotate. The rotating shaft then drives the blades on the copper sleeve to rotate, causing blade one to separate from air inlet one and blade two to cover air inlet two, thus achieving the purpose of opening air inlet one and closing air inlet two. Conversely, when air inlet one needs to be closed and air inlet two needs to be open, the rotary cylinder simply needs to be controlled to move in the opposite direction.
[0006] Preferably, the included angle between blade one and blade two is greater than degrees.
[0007] Preferably, a reinforcing rib is fixedly installed between the first blade and the second blade. By fixing the reinforcing rib between the first blade and the second blade, the overall strength and rigidity of the first blade and the second blade are effectively improved, ensuring that the first blade and the second blade can remain stable and are not easily deformed or damaged when rotating at high speed and frequently switching air inlets.
[0008] Preferably, the first blade can cover the first air inlet by rotating the shaft, and the second blade can cover the second air inlet by rotating the shaft.
[0009] Preferably, the other end of the partitioned exhaust box is provided with an air outlet.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0018] Please see Figure 1-4This utility model provides a pipe interchange valve for laser-cut pipes and plates, including a partitioned exhaust box 1. One end of the partitioned exhaust box 1 is fixedly connected to two symmetrically arranged air inlets 3 and 4. The front and back of the partitioned exhaust box 1 are respectively covered with a cover 2 and a cover 8. A rotating shaft 9 is rotatably connected between the cover 2 and the cover 8. A copper sleeve 13 is fixedly fitted onto the surface of the rotating shaft 9. A blade 10 and a blade 2 11 are fixed to the surface of the copper sleeve 13. One end of the rotating shaft 9 passes through the cover 2 and is fixed to a connecting rod 5. One end of the connecting rod 5 is rotatably connected to the output end of a rotary cylinder 6. The end of the rotary cylinder 6 opposite to the output end is rotatably connected to the cover 2 through a cylinder rotating shaft 12.
[0019] The angle between blade 10 and blade 21 is greater than 90 degrees.
[0020] Specifically, to prevent the air inlet 2 from being completely covered by the air inlet 2 when the air inlet 10 is open.
[0021] A reinforcing rib plate 14 is fixedly installed between blade plate 10 and blade plate 2.
[0022] Specifically, by fixing the reinforcing rib 14 between blade 10 and blade 21, the overall strength and rigidity of blade 10 and blade 21 are effectively improved, ensuring that blade 10 and blade 21 can remain stable and are not easily deformed or damaged when rotating at high speed and frequently switching air inlets.
[0023] Blade 10 can cover air inlet 4 by rotating shaft 9, and blade 2 11 can cover air inlet 4 by rotating shaft 9.
[0024] Specifically, operators can easily switch between air inlet 3 and air inlet 4 quickly by controlling the start and stop of the rotary cylinder 6.
[0025] The other end of the partitioned exhaust box 1 is provided with an air outlet 7.
[0026] Working principle: During use, air inlet 3 is connected to the pipe for laser cutting, and air inlet 4 is connected to the pipe for laser cutting sheet metal. When pipe cutting is required, i.e., air inlet 3 is connected and air inlet 4 is closed, the rotary cylinder 6 is activated. The output end of the rotary cylinder 6 drives the connecting rod 5 to move, the connecting rod 5 drives the rotating shaft 9 to rotate, and the rotating shaft 9 drives the blades 10 and 11 on the copper sleeve 13 to rotate, causing blade 10 to separate from air inlet 3 and blade 11 to cover air inlet 4. At this time, the exhaust gas generated by pipe cutting can enter the partitioned exhaust box 1 through air inlet 3 and then be discharged from the air outlet 7. When sheet metal cutting is required, i.e., air inlet 3 is closed and air inlet 4 is open, the rotary cylinder 6 is controlled to move in the opposite direction, driving the connecting rod 5, rotating shaft 9, etc. to rotate in the opposite direction, so that blade 10 covers air inlet 3, and blade 2 11 separates from air inlet 4. The exhaust gas generated by sheet metal cutting enters the partitioned exhaust box 1 through air inlet 4, and is then discharged from air outlet 7.
[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
