Description

Technical Field

[0001] The invention relates to the technical field of pipe cutting, in particular to a cutting device for processing a desulfurization and denitrification spray gun. Background Art

[0002] Desulfurization is a technical process that removes sulfide compounds (such as sulfur dioxide) produced during combustion by chemical or physical methods. This technology is mainly used in industries such as coal burning, industrial production and power generation. The purpose of desulfurization is to reduce sulfur dioxide emissions, reduce air pollution and the generation of acid rain. Desulfurization can achieve the effect of removing sulfide compounds through processes such as absorption, oxidation and reduction. Denitrification is a technical process that removes nitrogen oxides (such as nitrogen oxides, nitrogen monoxide, etc.) produced during combustion by chemical or physical methods. Similar to desulfurization, denitrification is mainly used in industries such as coal burning, industrial production and power generation. The purpose of denitrification is to reduce nitrogen oxide emissions, reduce air pollution and the formation of acid rain. Denitrification technology includes selective catalytic reduction Desulfurization and denitrification are important environmental protection technologies used to reduce the emission of sulfur dioxide and nitrogen oxides produced during the combustion process. The application of desulfurization and denitrification technologies can improve air quality, reduce air pollution and the formation of acid rain. In the field of environmental protection, continuously promoting the improvement and application of desulfurization and denitrification technologies is essential to protecting human health and the ecological environment. Desulfurization and denitrification spray guns are mainly used to atomize ammonia water or urea solution and spray it into the flue gas treatment system to achieve the purpose of desulfurization and denitrification. During the production and processing of desulfurization and denitrification spray guns, cutting equipment is required to cut the metal pipe into a certain length, and then punch, grind, weld and other processing steps to make the spray gun.

[0003] When using the existing cutting equipment, it is necessary to fix the pipe first and then cut the pipe. After the pipe cutting is completed, the pipe is loosened and then the material is fed and the operation is cyclical. This pipe cutting method requires waiting during the period of loosening the pipe, feeding and fixing the pipe, which will cause pauses and make it impossible to cut the pipe continuously, resulting in low cutting efficiency. Moreover, the current automatic cutting equipment requires the cooperation of multiple driving elements to complete the steps of automatic clamping, automatic cutting and automatic loosening, which will result in high production costs and high failure rates. For this reason, we propose a cutting device for desulfurization and denitrification spray gun processing to solve the above problems. Summary of the invention

A number of supporting wheels 10 are rotatably provided on the inner sides of the two outer rings 6. A number of positioning frames 11 are fixedly provided on the outer periphery of the inner ring 5. The pipe fitting is located between the inner ring 5 and the outer ring 6. A positioning frame 11, two guide frames 9 and four supporting wheels 10 are required to carry and guide one pipe fitting. Before cutting the pipe, the pipe fitting needs to be inserted into the receiving holes on the two guide frames 9 so that the pipe fitting passes through the inner ring 5 and the two outer rings 6, so that the pipe fitting can be carried and can also be guided during feeding.

[0034] like Figure 2 , Figures 4 to 8 , Fig.10 , Fig.11As shown, an automatic cutting component is arranged inside the bearing guide component, and the automatic cutting component is used for automatically and continuously cutting pipe fittings. The automatic cutting component comprises a driving shaft 3, a cutting blade 4, and an annular motion component. The driving shaft 3 is used to drive the annular motion component, and the annular motion component is used to drive the cutting blade 4 to make circular motion. The automatic cutting component also comprises a fixed frame 12, and the fixed frame 12 rotates on the outer periphery of the driving shaft 3, and the fixed frame 12 is fixed on one side of the inner ring 5.

A through hole is provided on one side of the L-shaped semi-ring frame 15, and a cutting shaft 16 is rotatably provided on the inner side of the through hole. The cutting blade 4 is fixed on the outer periphery of the cutting shaft 16. The semi-ring part of the L-shaped semi-ring frame 15 and the outer ring 6 are coaxial shaft structures. The cutting blade 4 is located between the two outer rings 6. The outer periphery of the driving shaft 3 is connected to the outer periphery of the cutting shaft 16 through a belt and a pulley transmission. After the pipe fitting is placed, the cutting step can be performed. When performing the cutting step, the motor 13 needs to be turned on. After the motor 13 is turned on, the driving shaft 3 will be driven to rotate through the bevel gear. When the driving shaft 3 rotates, the cutting shaft 16 and the cutting blade 4 will be rotated through the belt and the pulley. The cutting blade 4 can cut the pipe fitting when it rotates. During the rotation of the cutting blade 4, the annular motion component will drive the cutting blade 4 to make a circular motion. The cutting blade 4 makes a circular motion during the rotation, and the pipe fitting can be automatically and continuously cut.

[0035] like Figures 2 to 6 , Figure 8 , Fig.10 , Fig.11 As shown, the annular motion component includes an inner gear ring 17, which is fixed on the inner wall of the inner ring 5, a driving gear 18 is fixedly provided on the outer periphery of the driving shaft 3, a through hole is provided on one side of the cutting frame 14, a driving shaft 19 is rotatably provided on the inner side of the through hole, a planetary gear 20 is rotatably provided on the outer periphery of the driving shaft 19, the planetary gear 20 and the driving gear 18 are located inside the inner gear ring 17, the planetary gear 20 is connected to the inner gear ring 17 by meshing transmission, and the driving gear 18 is connected to the planetary gear 20 by meshing transmission. During the cutting of the pipe fitting, the driving shaft 3 will drive the driving gear 18 to rotate, and the rotation of the driving gear 18 will drive the planetary gear 20 to rotate. Since the planetary gear 20 is meshed with the inner gear ring 17 in a fixed state, the planetary gear 20 will also make a circular motion while rotating, and the planetary gear 20 will drive the cutting frame 14 and the driving shaft 19 to make a circular motion together, so that the cutting blade 4 can be driven to make a circular motion, thereby realizing automatic continuous cutting.

[0036] like Figure 4 , Figure 6 , Figure 7 , Fig.12 As shown, an automatic clamping and loosening assembly is provided between the automatic cutting assembly and the load-bearing guide assembly, the automatic clamping and loosening assembly is used to position the pipe fitting, the automatic clamping and loosening assembly is used to emboss the pipe fitting, the automatic cutting assembly is used to drive the automatic clamping and loosening assembly to continuously and automatically clamp and loosen, the annular motion assembly is used to drive the automatic clamping and loosening assembly to continuously and automatically clamp and loosen, the annular motion assembly is used to drive the automatic clamping and loosening assembly to perform circular motion, and the automatic clamping and loosening assembly can continuously and automatically clamp and loosen during the circular motion, the automatic clamping and loosening assembly includes a positioning semi-ring 21, the positioning semi-ring 21 is fixed on the outer periphery of the L-shaped semi-ring frame 15, the positioning semi-ring 21 and the outer ring 6 are coaxial shaft structures, and the positioning semi-ring 21 An anti-cutting hole is provided on the outer circumference, and the cutting disc 4 is located inside the anti-cutting hole. A semi-ring flexible anti-skid pad 22 and two embossed semi-ring frames 23 are provided on the two sides away from each other of the cutting disc 4. The semi-ring flexible anti-skid pad 22 and the embossed semi-ring frame 23 are fixed on the outer circumference of the positioning semi-ring 21. One end of the semi-ring flexible anti-skid pad 22 and the embossed semi-ring frame 23 are both chamfered. An embossed grid frame 24 is fixed on the outer circumference of the embossed semi-ring frame 23. A drop hopper 33 is fixed on the upper side of the bottom plate 1. During the cutting of the pipe fitting, the pipe fitting needs to be placed first, then clamped, and then cut. During the rotation of the driving shaft 3, the cutting frame 14 will be driven to make a circular motion through the annular motion component. When the cutting frame 14 performs circular motion, it will drive the L-shaped semi-ring frame 15, the positioning semi-ring 21, the semi-ring flexible anti-skid pad 22, and the embossed semi-ring frame 23 to perform circular motion together. During the circular motion, the semi-ring flexible anti-skid pad 22, the embossed semi-ring frame 23, and the embossed mesh frame 24 will gradually approach and contact the pipe fittings. When the embossed mesh frame 24 contacts the pipe fittings, the pipe fittings will be pressed between the embossed mesh frame 24 and the multiple supporting wheels 10. When the pipe fittings are pressed, the pipe fittings will not contact the positioning frame 11, and the pipe fittings will not contact the inner wall of the accommodating hole. In addition, during the circular motion of the embossed mesh frame 24, mesh grooves will be pressed on the outer wall of the pipe fittings, so there is no need to perform embossing processing on the pipe fittings later. It can ensure that the pipe will not move during the cutting process, and the pipe will also rotate. At the same time, the semi-ring flexible anti-skid pad 22 can prevent slipping, so that the pipe can be clamped. When the semi-ring flexible anti-skid pad 22, the embossed semi-ring frame 23, and the embossed grid frame 24 are separated from the pipe, the pipe will be automatically released, so that automatic continuous clamping and loosening can be achieved. The pipe will be clamped first and then cut. When the pipe is cut and separated from the embossed grid frame 24, the corresponding pipe needs to be pushed forward manually so that the long pipe to be cut moves to the cutting position, and the cut pipe is separated from the guide frame 9 and falls on the drop hopper 33, so that unloading and feeding can be completed.

[0037] like Fig.12As shown, the positioning half ring 21 is provided with a burr removal component, which includes an elastic half ring pad 25, a semi-ring groove is provided on the outer periphery of the positioning half ring 21, and the elastic half ring pad 25 is fixed on the inner side of the semi-ring groove. A grinding half ring 26 is fixed on the outer periphery of the elastic half ring pad 25, and the grinding half ring 26 is located on one side of the cutting blade 4. The middle part of the grinding half ring 26 is a right-angled pointed cone-shaped protrusion structure. During the cutting of the pipe fitting, the positioning half ring 21 will drive the elastic half ring pad 2 5 and the grinding half ring 26 make circular motion, and the pipe fitting itself also rotates. When the cutting blade 4 cuts off the pipe fitting and moves away from the pipe fitting, the grinding half ring 26 will approach and contact the incision of the pipe fitting. When the grinding half ring 26 contacts the incision of the pipe fitting, the burrs at the incision of the pipe fitting can be removed by friction while the pipe fitting itself rotates. The elasticity of the elastic half ring pad 25 can make the grinding half ring 26 stick to the incision of the pipe fitting, thereby completing the burr removal.

[0038] like Figures 1 to 3 , Figure 5 , Fig.10As shown, an auxiliary length-fixing component is provided on one side of the automatic clamping and loosening component, and the auxiliary length-fixing component is used to assist in determining the length of the cut pipe, and the automatic cutting component is used to drive the auxiliary length-fixing component to perform continuous assistance, and the annular motion component is used to drive the auxiliary length-fixing component to perform continuous assistance, and the annular motion component is used to assist the length-fixing component to perform circular motion, and the auxiliary length-fixing component can perform continuous assistance during the circular motion, and the auxiliary length-fixing component includes a driving frame 27, and the driving frame 27 is fixed on the inner wall of the positioning semi-ring 21, and a guide rod 28 is fixed on one side of the driving frame 27, and the guide rod 28 and the belt A plurality of reinforcing rods 29 are fixed between the movable frame 27, a following frame 30 is slidably provided on the outer periphery of the guide rod 28, and the following frame 30 and the guide rod 28 are detachably connected by bolts, an auxiliary semi-ring 31 is provided on one side of the positioning semi-ring 21, and a drop hopper 33 is located below the auxiliary semi-ring 31, and the following frame 30 is fixed on the inner side of the auxiliary semi-ring 31, and an arc-shaped ramp frame 32 is fixed at one end of the auxiliary semi-ring 31. Before use, the positions of the following frame 30 and the auxiliary semi-ring 31 should be adjusted according to the length of the cut pipe. When the position of the auxiliary semi-ring 31 needs to be adjusted, it is necessary to first Remove the bolts between the follower frame 30 and the guide rod 28, and then slide and adjust the position of the follower frame 30 and the auxiliary half ring 31. After the position of the auxiliary half ring 31 is determined, tighten the bolts between the follower frame 30 and the guide rod 28 to lock the follower frame 30 on the guide rod 28. During the cutting of the pipe, the positioning half ring 21 will drive the auxiliary half ring 31 and the arc-shaped ramp frame 32 to make a circular motion. When the pipe is cut and separated from the embossed grid frame 24, it is necessary to manually push the corresponding pipe to be cut forward. When pushing the pipe to be cut forward, the cut pipe can be pushed out, and at the same time Push the pipe to be cut to the cutting position to complete the unloading and loading. When pushing the pipe to be cut forward, the pipe can be pushed a certain distance more without the need for precise pushing. During the circular motion of the auxiliary semi-ring 31 and the arc-shaped ramp frame 32, the arc-shaped ramp frame 32 will gradually approach and contact the pipe pushed forward. After the arc-shaped ramp frame 32 contacts the pipe pushed forward, it will push the pipe to be cut backward, and the pipe can be gradually introduced into the auxiliary semi-ring 31, so that one end of the pipe to be cut can be attached to the auxiliary semi-ring 31, thereby realizing automatic and continuous auxiliary fixed length, which is easy to use.
