Description

Technical Field

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

[0002] Desulfurization is a technical process that removes sulfur compound (such as sulfur dioxide) generated during the combustion process through chemical or physical methods. This technology is mainly applied in industries such as coal combustion, 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 sulfur compounds through processes such as absorption, oxidation, and reduction. Denitrification is a technical process that removes generated nitrogen oxides (such as nitrogen oxides, nitric oxide, etc.) through chemical or physical methods during the combustion process. Similar to desulfurization, denitrification is mainly applied in industries such as coal combustion, 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 technologies include methods such as selective catalytic reduction (SCR) and selective non-catalytic reduction (SNCR). Desulfurization and denitrification is an important environmental protection technology used to reduce the emissions of sulfur dioxide and nitrogen oxides generated during the combustion process. Through the application of desulfurization and denitrification technologies, air quality can be improved, and air pollution and the formation of acid rain can be reduced. In the field of environmental protection, continuously promoting the improvement and application of desulfurization and denitrification technologies is crucial for 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 metal pipes into a certain length, and then perform processing steps such as punching, grinding, and welding to make spray guns.

[0003] When the existing cutting equipment is in use, it is necessary to first fix the pipe fittings and then perform pipe cutting. After the pipe cutting is completed, the pipe fittings are released, and then the feeding is carried out, and the operation is repeated. During the process of releasing the pipe fittings, feeding, and fixing the pipe fittings, waiting is required, resulting in pauses and the inability to continuously cut pipes, thus causing low cutting efficiency. Moreover, current automatic cutting equipment requires multiple driving elements to cooperate to complete the steps of automatic clamping, automatic cutting, and automatic releasing, resulting in high production costs and high failure rates. Therefore, we have proposed a cutting device for processing desulfurization and denitrification spray guns to solve the above problems. Summary of the Invention

Specific implementation mode

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0033] Refer to Figures 1 to 12 , a cutting device for processing a desulfurization and denitration spray gun, including a bottom plate 1 and a pipe fitting. A chassis 2 is fixedly arranged on the upper side of the bottom plate 1. A bearing and guiding assembly is arranged on the upper side of the chassis 2. The bearing and guiding assembly is used to bear the pipe fitting. The bearing and guiding assembly includes an inner ring 5, two outer rings 6 and a plurality of connecting plates 8. The inner ring 5 is located inside one of the outer rings 6. The inner ring 5 and the outer ring 6 are concentric shaft structures. A plurality of connecting blocks 7 are fixedly arranged between the outer periphery of the inner ring 5 and the inner wall of one of the outer rings 6. The connecting plates 8 are fixed on the outer peripheries of the two outer rings 6. Some of the connecting plates 8 are fixed on the upper side of the chassis 2. Guiding frames 9 are fixedly arranged on the mutually remote sides of the two outer rings 6. An accommodation hole is arranged on one side of the guiding frame 9. The pipe fitting is located inside the accommodation hole. The inner diameter of the accommodation hole is larger than the diameter of the pipe fitting. A plurality of supporting wheels 10 are rotatably arranged inside the two outer rings 6. A plurality of positioning frames 11 are fixedly arranged on the outer periphery of the inner ring 5. The pipe fitting is located between the inner ring 5 and the outer ring 6. One positioning frame 11, two guiding frames 9 and four supporting wheels 10 are required to bear and guide one pipe fitting. Before cutting the pipe, the pipe fitting needs to be inserted into the accommodation holes on the two guiding frames 9 so that the pipe fitting passes through the inner ring 5 and the two outer rings 6, so as to bear the pipe fitting and guide the pipe fitting during feeding.

[0034] Such as Figure 2 , Figures 4 to 8 , Figure 10 , Figure 11As shown in the figure, an automatic cutting component is provided inside the bearing and guiding component. The automatic cutting component is used for automatically and continuously cutting pipe fittings. The automatic cutting component includes 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 perform a circular motion. The automatic cutting component further includes a fixing frame 12. The fixing frame 12 rotates on the outer periphery of the driving shaft 3 and is fixed on one side of the inner ring 5. The driving shaft 3 and the inner ring 5 are of a concentric shaft structure. A motor 13 is fixedly provided on one side of the fixing frame 12. The motor 13 is externally connected to a power source and a switch through a wire. The shaft end of the motor 13 is connected to the outer periphery of the driving shaft 3 through bevel gear transmission. A cutting frame 14 is rotatably provided on the outer periphery of the driving shaft 3. The cutting frame 14 is located inside the inner ring 5. An L-shaped half-ring frame 15 is fixedly provided on one side of the cutting frame 14. A through hole is provided on one side of the L-shaped half-ring frame 15. A cutting shaft 16 is rotatably provided inside the through hole. The cutting blade 4 is fixed on the outer periphery of the cutting shaft 16. The half-ring part of the L-shaped half-ring frame 15 is of a concentric shaft structure with the outer ring 6. 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 for transmission. After the pipe fitting is placed, the cutting step can be carried out. When carrying out the cutting step, the motor 13 needs to be turned on. After the motor 13 is turned on, it will drive the driving shaft 3 to rotate through the bevel gear. When the driving shaft 3 rotates, it will drive the cutting shaft 16 and the cutting blade 4 to rotate through the belt and the pulley. When the cutting blade 4 rotates, it can cut the pipe fitting. During the rotation of the cutting blade 4, the annular motion component will drive the cutting blade 4 to perform a circular motion. When the cutting blade 4 performs a circular motion during rotation, the pipe fitting can be automatically and continuously cut.

[0035] As Figures 2 to 6 , Figure 8 , Figure 10 , Figure 11 shown, the annular motion component includes an internal gear ring 17. The internal gear ring 17 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 inside 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 internal gear ring 17. The planetary gear 20 is connected to the internal gear ring 17 through meshing transmission. The driving gear 18 is connected to the planetary gear 20 through meshing transmission. During the cutting of the pipe fitting, the driving shaft 3 will drive the driving gear 18 to rotate. The rotation of the driving gear 18 will drive the planetary gear 20 to rotate. Since the planetary gear 20 meshes with the fixed internal gear ring 17, the planetary gear 20 will also perform a circular motion while rotating. The planetary gear 20 will drive the cutting frame 14 and the driving shaft 19 to perform a circular motion together, so as to drive the cutting blade 4 to perform a circular motion, and thus automatic continuous cutting can be realized.

[0036] As Figure 4 ,Figure 6 , Figure 7 , Figure 12 As shown in Figure 6 , Figure 7 , and Figure 12 , an automatic clamping and loosening assembly is provided between the automatic cutting assembly and the bearing and guiding assembly. The automatic clamping and loosening assembly is used to position the pipe fitting and perform embossing on the pipe fitting. The automatic cutting assembly is used to drive the automatic clamping and loosening assembly to perform continuous automatic clamping and loosening. The annular motion assembly is used to drive the automatic clamping and loosening assembly to perform continuous automatic clamping and loosening, and the annular motion assembly is used to drive the automatic clamping and loosening assembly to perform circular motion. During the circular motion, the automatic clamping and loosening assembly can perform continuous automatic clamping and loosening. The automatic clamping and loosening assembly includes a positioning semi-ring 21, which 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 structures. Anti-cutting holes are provided on the outer periphery of the positioning semi-ring 21. The cutting blade 4 is located inside the anti-cutting holes. On both sides of the cutting blade 4 away from each other, there are a semi-ring flexible anti-slip pad 22 and two embossing semi-ring frames 23. The semi-ring flexible anti-slip pad 22 and the embossing semi-ring frames 23 are fixed on the outer periphery of the positioning semi-ring 21. One end of the semi-ring flexible anti-slip pad 22 and the embossing semi-ring frames 23 are provided with chamfers. An embossing wire frame 24 is fixedly provided on the outer periphery of the embossing semi-ring frame 23. A blanking hopper 33 is fixedly provided on the upper side of the bottom plate 1. During the cutting of the pipe fitting, it is necessary to first place the pipe fitting, then clamp the pipe fitting, and then cut the pipe fitting. During the rotation of the driving shaft 3, the cutting frame 14 will be driven by the annular motion assembly to perform circular motion. 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-slip pad 22, and the embossing semi-ring frames 23 to perform circular motion together. During the circular motion of the semi-ring flexible anti-slip pad 22, the embossing semi-ring frames 23, and the embossing wire frame 24, they will gradually approach and contact the pipe fitting. When the embossing wire frame 24 contacts the pipe fitting, the pipe fitting will be pressed between the embossing wire frame 24 and the plurality of support wheels 10. When the pipe fitting is pressed, the pipe fitting will not contact the positioning frame 11, and at the same time, the pipe fitting will not contact the inner wall of the receiving hole. Moreover, during the circular motion of the embossing wire frame 24, a mesh-shaped groove pattern will be pressed on the outer wall of the pipe fitting. Subsequently, there is no need to perform embossing processing on the pipe fitting, and at the same time, it can be ensured that the pipe fitting will not move during the cutting process, and the pipe fitting will also rotate. At the same time, the semi-ring flexible anti-slip pad 22 can prevent slipping, so as to clamp the pipe fitting. When the semi-ring flexible anti-slip pad 22, the embossing semi-ring frames 23, and the embossing wire frame 24 are separated from the pipe fitting, the pipe fitting will be automatically loosened, so as to achieve automatic continuous clamping and loosening, and the pipe fitting will be clamped first and then cut. When the pipe fitting is cut off and separated from the embossing wire frame 24, it is necessary to manually push the corresponding pipe fitting forward, so that the long pipe fitting to be cut advances to the cutting position, and the cut pipe fitting is separated from the guiding frame 9 and falls on the blanking hopper 33, so as to complete blanking and feeding.

[0037] As Figure 12As shown, a burr removal component is provided on the positioning semi-ring 21. The burr removal component includes an elastic semi-ring pad 25. A semi-ring groove is provided on the outer periphery of the positioning semi-ring 21. The elastic semi-ring pad 25 is fixed to the inner side of the semi-ring groove. A grinding semi-ring 26 is fixedly provided on the outer periphery of the elastic semi-ring pad 25. The grinding semi-ring 26 is located on one side of the cutting disc 4. The middle part of the grinding semi-ring 26 is a right-angled sharp cone-shaped convex structure. During the cutting of the pipe fitting, the positioning semi-ring 21 will drive the elastic semi-ring pad 25 and the grinding semi-ring 26 to make a circular motion. At the same time, the pipe fitting itself will also rotate. When the cutting disc 4 cuts off the pipe fitting and moves away from the pipe fitting, the grinding semi-ring 26 will approach and contact the cut of the pipe fitting. When the grinding semi-ring 26 contacts the cut of the pipe fitting, while the pipe fitting itself is rotating, the burrs at the cut of the pipe fitting can be rubbed and removed. The elasticity of the elastic semi-ring pad 25 enables the grinding semi-ring 26 to adhere to the cut of the pipe fitting, thereby completing the burr removal.

[0038] As Figures 1 to 3 , Figure 5 , Figure 10As shown, an auxiliary length - determining component is provided on one side of the automatic clamping and loosening component. The auxiliary length - determining component is used to assist in determining the length of the cut pipe fitting. The automatic cutting component is used to drive the auxiliary length - determining component for continuous assistance. The annular motion component is used to drive the auxiliary length - determining component for continuous assistance. The annular motion component is used to make the auxiliary length - determining component perform circular motion. The auxiliary length - determining component can perform continuous assistance during the circular motion. The auxiliary length - determining component includes a driving frame 27. The driving frame 27 is fixed on the inner wall of the positioning semi - ring 21. A guide rod 28 is fixedly provided on one side of the driving frame 27. A number of reinforcing rods 29 are fixedly provided between the guide rod 28 and the driving frame 27. A follower frame 30 is slidably provided on the outer periphery of the guide rod 28. The follower frame 30 is detachably connected to the guide rod 28 by bolts. An auxiliary semi - ring 31 is provided on one side of the positioning semi - ring 21. The blanking hopper 33 is located below the auxiliary semi - ring 31. The follower frame 30 is fixed inside the auxiliary semi - ring 31. One end of the auxiliary semi - ring 31 is fixedly provided with an arc - shaped ramp frame 32. Before use, according to the length of the cut pipe fitting, the positions of the follower frame 30 and the auxiliary semi - ring 31 need to be adjusted. When adjusting the position of the auxiliary semi - ring 31, the bolts between the follower frame 30 and the guide rod 28 need to be removed first, and then the positions of the follower frame 30 and the auxiliary semi - ring 31 can be slidably adjusted. After the position of the auxiliary semi - ring 31 is determined, the bolts between the follower frame 30 and the guide rod 28 need to be tightened to lock the follower frame 30 on the guide rod 28. During the cutting of the pipe fitting, the positioning semi - ring 21 will drive the auxiliary semi - ring 31 and the arc - shaped ramp frame 32 to perform circular motion. When the pipe fitting is cut and separated from the corrugated wire mesh frame 24, the corresponding pipe fitting to be cut needs to be manually pushed forward. When pushing forward the pipe fitting to be cut, the cut pipe can be pushed out, and at the same time, the pipe fitting to be cut can be pushed to the cutting position, thus completing blanking and loading. When pushing forward the pipe fitting to be cut, the pipe fitting can be pushed a certain distance more, and precise pushing is not required. 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 pushed - forward pipe fitting. After the arc - shaped ramp frame 32 contacts the pushed - forward pipe fitting, it will push the pipe fitting to be cut backward, and the pipe fitting can be gradually guided into the auxiliary semi - ring 31, so that one end of the pipe fitting to be cut can be attached to the auxiliary semi - ring 31, thus realizing automatic continuous auxiliary length determination and being convenient for use.
