Description

Technical Field

[0001] The invention relates to the technical field of pressure vessel cutting machine tools, in particular to a pressure vessel cutting method. Background Art

[0002] Pressure vessels refer to closed equipment that holds gas or liquid and bears a certain pressure. Pressure vessels are mainly used to complete the physical and chemical reactions of working media, which are called reaction vessels. Leakage and explosion may occur during use. The power generated by leakage and explosion is very strong and may cause serious consequences. Therefore, pressure vessels are classified as special equipment, and there are strict requirements for their production and use.

[0003] When producing pressure vessels, cutting equipment is needed to cut the raw materials. The process usually involves cutting the cylindrical workpiece, and then welding the opening of the cylindrical workpiece with a circular plate to achieve the purpose of sealing. Therefore, a pressure vessel cutting device such as that disclosed in Chinese patent CN202321059949.X can be used. The cutting device drives the cutting disc to rotate by a driving motor to achieve the effect of cutting the pressure vessel. A servo motor is set to drive the adjusting screw to rotate, and the threaded sleeve and the telescopic cylinder are displaced by the adjusting screw rotation, so as to facilitate the adjustment of the position of the cutting disc to cut different sizes.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] For example, see Figures 1 to 9 The present invention provides a cutting method: A cutting method for a pressure vessel is as follows First, one end of the pressure vessel is passed through the opening of the annular fixing frame 11 and pressed against the surface of the rotating disk 5, and then the threaded rod 3 4 is rotated to move the rotating disk 5, and the position of the pressure vessel cutting is further adjusted. After the position is determined, the threaded rod 2 31 is rotated to fix the pressure vessel, and the threaded rod 1 7 is rotated again to make the circular cutter disk 20 press downward against the pressure vessel, and then the circular cutter disk 20 is operated to cut the pressure vessel, and while cutting, the motor 10 is started to drive the pressure vessel to rotate; While the motor 10 drives the pressure vessel to rotate, the nozzle 17 will also spray water to cool the circular knife disc 20, and the sprayed water will flow back into the water tank 12 after being filtered by the filter plate 15 for spraying again.

[0023] It is worth noting that the upper surface of the carrier machine 1 is fixedly connected with an annular fixing frame 11, and a fixing mechanism is arranged on the annular fixing frame 11, and the fixing mechanism can make the pressure vessel rotate.

The pressure vessel cutting device also includes a cutting assembly, which is arranged on the fixing frame 8, and the cutting assembly includes: A through slide groove is provided on the upper surface of the threaded rod 7 and the fixed frame 8, and the lower surface of the slide groove wall is rotatably connected to the lower end surface of the threaded rod 7. The surface of the threaded rod 7 is also threadedly connected to a sliding plate 6, and a through slot is provided on the upper surface of the sliding plate 6, and a sliding rod 18 is slidably connected to the slot wall of the slot, and a rotating frame 19 is fixedly connected to the lower surface of the sliding rod 18, and a spring 21 is fixedly connected to the upper surface of the rotating frame 19, and the inner wall of the rotating frame 19 is rotatably connected to the side surface of the circular cutter disc 20.

[0024] When using the present cutting machine, firstly, the pressure vessel raw material to be cut is placed on the carrying machine 1 through the annular fixing frame 11, and then the threaded rod 17 is rotated to make the sliding plate 6 move downward. After the sliding plate 6 moves downward, it will further drive the circular cutter disc 20 to move downward. The circular cutter disc 20 moves downward and will first contact the surface of the pressure vessel, and then stop moving downward, so that the distance between the rotating frame 19 and the sliding plate 6 becomes smaller and smaller, further squeezing the spring 1 21, so that the spring 1 21 has elastic properties, so that the blade surface of the circular cutter disc 20 is further made to be in close contact with the surface of the pressure vessel; The setting of the cutting assembly can further improve the cutting efficiency of the pressure vessel by making the circular cutter disc 20 close to the surface of the pressure vessel and making the circular cutter disc 20 press the pressure vessel downward, which will further improve the actual use effect of the cutting machine tool when in use.

[0026] After the pressure vessel raw material is placed on the carrying machine 1 through the annular fixing frame 11, the threaded rod 2 31 is rotated to further drive the sliding block 1 33 to move away from the rotating block 32, which further drives the set 30 to rotate counterclockwise. The counterclockwise rotation of the set 30 further moves the square set 23, which further drives the bent rod 22 to deflect in a certain direction, so that the roller 34 is close to the surface of the pressure vessel, thereby achieving the purpose of fixing the pressure vessel; In addition, in the cutting machine, the position of the fixed plate 1 3 can be further changed by rotating the threaded rod 3 4, so as to adjust the position of the cutting pressure vessel; The setting of the fixing assembly uses three rollers 34 to closely contact the surface of the pressure vessel, thereby fixing the pressure vessel on the cutting machine, so that the pressure vessel will not move forward and backward during the subsequent cutting process, further improving the accuracy of the cutting machine in cutting the pressure vessel, and also through the setting of the rotating disk 5, it can support one end of the pressure vessel, further improving the fixing effect of the pressure vessel.
