Description

Technical Field

[0001] The present invention relates to the technical field of deburring, and specifically to an efficient self-centering device for deburring the outer surface of stainless steel seamless steel pipes. Background Art

[0002] During the production of stainless steel pipes, burrs usually appear on their surfaces. These burrs not only reduce the surface flatness of the stainless steel pipes but also affect the service performance of the stainless steel pipes. Therefore, deburring is an important step in the production process of stainless steel pipes, and a deburring device is required to remove the burrs.

[0003] However, during the deburring process of the stainless steel pipe surface, waste chips and a little bit of sparks will be generated. Since the grinding device continuously and rapidly grinds the outer surface of the stainless steel, the waste chips and a little bit of sparks generated by grinding will splash, seriously affecting the working environment of the staff. Summary of the Invention

[0004] The purpose of the present invention is to provide an efficient self-centering device for deburring the outer surface of stainless steel seamless steel pipes, which uses the ejected liquid to form an annular water curtain to effectively block the splashing waste chips and sparks, preventing the waste chips and sparks from splashing to the outside and affecting the working environment of the staff; at the same time, the water curtain can timely extinguish the splashing sparks and block them, preventing the sparks from splashing onto flammable substances or components, causing potential safety hazards.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An efficient self-centering device for deburring the outer surface of stainless steel seamless steel pipes, including a workbench, on which a grinding component for automatically switching the position of the steel pipe and driving the steel pipe to rotate is provided. Above the grinding component, a waste chip removing component for preventing waste chips and sparks from splashing is installed. The waste chip removing component includes a liquid storage cylinder located on the workbench for carrying liquid, a liquid outlet plate installed below the liquid storage cylinder for forming an annular water curtain after spraying the liquid, a water receiving tank installed below the liquid storage cylinder for receiving the water curtain, a positioning ring with a through groove at the center on the vertical axis of the water receiving tank, and a grinding block installed on the positioning ring for grinding and deburring the outer surface of the steel pipe; a flow splitting component is arranged inside the water curtain formed by the liquid outlet plate. The flow splitting component includes a second mounting seat installed on the positioning ring, a flow splitting plate installed above the second mounting seat. The surface of the flow splitting plate facing the outside of the steel pipe is designed as an inclined surface, and the top of the flow splitting plate divides the water curtain formed by the liquid outlet plate into two parts, and a part of the liquid cut by the inclined surface of the flow splitting plate splashes onto the surface of the steel pipe along the inclined surface.

[0006] Preferably, the grinding component includes an electric guide rod fixedly installed on the workbench, a moving table sliding on the electric guide rod, and a motor installed on the moving table.

[0007] Preferably, a fixture for clamping a steel pipe is installed at the output end of the motor.

[0008] Preferably, an electric slider that slides along the electric guide rod is installed on the moving table.

[0009] Preferably, the fixture and the positioning ring above are arranged along the same axis.

[0010] Preferably, the water receiving tank is fixedly installed on the outside of the positioning ring, and the water receiving tank is fixedly installed on the workbench.

[0011] Preferably, the water receiving tank is located below the liquid outlet tray. A plurality of nozzles are uniformly installed at the bottom of the liquid outlet tray along the axis of the liquid outlet tray. The diameter of the water receiving tank is 1.5 to 2 times the diameter of the liquid outlet tray.

[0012] Preferably, a first mounting seat is installed below the grinding block, and the first mounting seat is detachably installed on the positioning ring.

[0013] Preferably, one side of the water receiving tank is communicated with a recovery pipe whose one end is connected to the liquid storage cylinder.

[0014] Preferably, the second mounting seat is detachably installed on the positioning ring.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. The present invention uses a water pump inside the liquid storage cylinder to spray the liquid through the nozzles on the liquid outlet tray. Since a plurality of nozzles are uniformly installed along the axis of the liquid outlet tray, the sprayed liquid will form an annular water curtain. The water curtain surrounds the grinding block and the steel pipe inside it. Thus, during the deburring and grinding process of the steel pipe, the water curtain can effectively block the flying waste chips and sparks, preventing the waste chips and sparks from splashing to the outside and affecting the working environment of the staff; in addition, the water curtain can extinguish the flying sparks in the first time and block them, preventing the sparks from splashing onto flammable objects or components and causing potential safety hazards.

[0017] 2. The present invention collects the water curtain that falls into the water receiving tank, and at the same time collects the waste chips, which is convenient for the staff to collect and improves the cleanliness of the working environment. At the same time, the water pump installed on the recovery pipe can recycle the liquid in the water receiving tank back into the liquid storage cylinder to form a cycle, saving water resources. At the same time, a filter screen can be set at the connection between the recovery pipe and the water receiving tank to filter the waste chips.

[0018] 3. During the process of deburring and grinding the outer part of the steel pipe surrounded by the water curtain in the present invention, due to the inclined surface design of the flow dividing plate, and the top of the flow dividing plate cutting the inner side of the water curtain, the orientation of the water curtain is divided into that the outer side of the water curtain still converges towards the water receiving tank, and the orientation of the inner side of the water curtain splashes along the inclined surface of the flow dividing plate. Since the inclined surface of the flow dividing plate faces the steel pipe, part of the liquid on the inner side of the water curtain splashes onto the surface of the steel pipe along the inclined surface of the flow dividing plate, which can clean and cool the steel pipe after deburring and grinding. At the same time, the splashing liquid has a certain pressure and can effectively remove the waste chips adhering to the surface of the steel pipe. Meanwhile, the splashing liquid can cooperate with the water curtain to further intercept and extinguish the sparks generated during grinding, enhancing the safety of the working environment.

DETAILED DESCRIPTION OF THE INVENTION

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0028] The present invention provides a high-efficiency self-centering deburring device for the outer surface of stainless steel seamless steel pipes, including a workbench 1. A grinding assembly 2 for automatically switching the position of the steel pipe and driving the steel pipe to rotate is provided on the workbench 1. Above the grinding assembly 2, a waste chip removal assembly 3 for preventing waste chips and sparks from splashing is installed. The waste chip removal assembly 3 includes a liquid storage cylinder 31 located on the workbench 1 for carrying liquid. Below the liquid storage cylinder 31, a liquid outlet plate 32 for forming an annular water curtain after spraying liquid is installed. Below the liquid storage cylinder 31, a water receiving tank 33 for receiving the water curtain is installed. On the vertical axis of the water receiving tank 33, a positioning ring 35 with a through groove at the center is provided. On the positioning ring 35, a grinding block 36 for grinding and deburring the outer surface of the steel pipe is installed; the grinding assembly 2 includes an electric guide rod 22 fixedly installed on the workbench 1. A moving table 21 slides on the electric guide rod 22. On the moving table 21, a motor 23 is installed. The output end of the motor 23 is installed with a fixture 24 for clamping the steel pipe. On the moving table 21, an electric slider sliding along the electric guide rod 22 is installed. The fixture 24 and the upper positioning ring 35 are arranged along the same axis; the water receiving tank 33 is fixedly installed on the outside of the positioning ring 35 and is fixedly installed on the workbench 1. The water receiving tank 33 is located below the liquid outlet plate 32. A plurality of nozzles are uniformly installed at the bottom of the liquid outlet plate 32 along the axis of the liquid outlet plate 32. The diameter of the water receiving tank 33 is 1.5 to 2 times the diameter of the liquid outlet plate 32. Below the grinding block 36, a first mounting seat 37 is installed. The first mounting seat 37 is detachably installed on the positioning ring 35; one side of the water receiving tank 33 is communicated with a recovery pipe 34 with one end connected to the liquid storage cylinder 31.

[0029] Refer to Figures 1 to 6 As shown, pass the steel pipe through the positioning ring 35 and fix it by clamping with the fixture 24. Then start the motor 23. The output end of the motor 23 drives the fixture 24 to rotate. Then, use the grinding block 36 above the positioning ring 35 and outside the steel pipe to deburr and grind the outer surface of the steel pipe. During this process, the electric slider can be controlled to move along the electric guide rod 22. The electric guide rod 22 drives the moving table 21 to move. The moving table 21 drives the motor 23 to move. The motor 23 drives the steel pipe to move through the fixture 24. Thus, the steel pipe can be automatically driven to rotate and the grinding position can be automatically changed, further improving the deburring and grinding effect;

[0030] In addition, by arranging the positioning ring 35 and the fixture 24 below along the same axis, based on the principle that two points determine a straight line, the steel pipe can be positioned efficiently, improving the quality of deburring and grinding;

[0031] In addition, while the deburring and grinding are being carried out, the liquid in the liquid storage cylinder 31 is sprayed out through the nozzles on the liquid outlet tray 32 by the water pump inside. Refer to Figures 5 to 6 As shown, since a plurality of nozzles are evenly installed along the axis of the liquid outlet tray 32, the sprayed liquid will form an annular water curtain. The water curtain surrounds the grinding block 36 and the steel pipe inside it. Thus, during the deburring and grinding process of the steel pipe, the water curtain can effectively block the flying waste chips and sparks, preventing the waste chips and sparks from splashing to the outside and affecting the working environment of the staff; in addition, the water curtain can extinguish the flying sparks immediately and block them, preventing the sparks from splashing onto flammable substances or components and causing potential safety hazards;

[0032] At the same time, the formation of the annular water curtain surrounds the deburring and grinding work inside the water curtain, which can reduce noise and prevent the noise generated by grinding from being transmitted to the outside and affecting the working environment;

[0033] In addition, the water curtain falls into the inside of the water receiving tank 33 for collection, and at the same time, the waste chips are collected, which is convenient for the staff to collect, improving the cleanliness of the working environment. At the same time, the water pump installed on the recovery pipe 34 can recycle the liquid inside the water receiving tank 33 back into the liquid storage cylinder 31 to form a cycle, saving water resources. At the same time, a filter screen can be set at the connection between the recovery pipe 34 and the water receiving tank 33 to filter the waste chips;

[0034] In addition, the detachable design of the grinding block 36 can adjust the position of the grinding block 36 according to the size of the steel pipe, adapting to steel pipes of different sizes and improving the practicality of its deburring work.

[0035] A flow splitting component 4 is arranged inside the liquid outlet tray 32 that forms the water curtain. The flow splitting component 4 includes a second mounting seat 41 installed on the positioning ring 35. A flow splitting plate 42 is installed above the second mounting seat 41. The surface of the flow splitting plate 42 facing the outside of the steel pipe is designed as an inclined surface, and the top of the flow splitting plate 42 divides the water curtain formed by the liquid outlet tray 32 into two parts. One part of the liquid that is split by the inclined surface of the flow splitting plate 42 splashes onto the surface of the steel pipe along the inclined surface. The second mounting seat 41 is detachably installed on the positioning ring 35.

[0036] Refer to Figures 3 to 7 As shown, during the process of the above-mentioned water curtain surrounding the outside of the steel pipe for deburring and grinding, refer to Figure 6As shown in the figure, due to the inclined surface design of the flow splitter plate 42, and the top of the flow splitter plate 42 cutting the inner side of the water curtain, the orientation of the water curtain is divided into two parts. The outer side of the water curtain still converges towards the water receiving tank 33, while the inner side of the water curtain splashes along the inclined surface of the flow splitter plate 42. Since the inclined surface of the flow splitter plate 42 faces the steel pipe, part of the liquid on the inner side of the water curtain splashes onto the surface of the steel pipe along the inclined surface of the flow splitter plate 42. This can clean and cool the steel pipe after deburring and polishing. At the same time, the splashing liquid has a certain pressure, which can effectively remove the waste chips adhering to the surface of the steel pipe. Additionally, the splashing liquid can cooperate with the water curtain to further block and extinguish the sparks generated during polishing, enhancing the safety of the working environment.

[0037] At the same time, part of the liquid that splashes onto the steel pipe will flow downward along the surface of the steel pipe and pass through the grinding block 36 and the unpolished part of the steel pipe where burrs have not been removed. This can lubricate and cool the grinding block 36 and pre-clean the unpolished part of the steel pipe where burrs have not been removed, preventing dust and impurities on the surface from affecting the deburring effect.

[0038] In addition, through the detachable design of the second mounting seat 41, the flow splitter plate 42 with different inclined surface angles can be selected according to the actual situation to control the angle and position of liquid splashing, improving its working effect. At the same time, the liquid inside the liquid storage cylinder 31 in this technical solution can be coolant or clean water, which can be selected according to the actual work.

[0039] Working principle: Pass the steel pipe through the positioning ring 35 and fix it with the fixture 24. Then start the motor 23. The output end of the motor 23 drives the fixture 24 to rotate. Then, use the grinding block 36 above the positioning ring 35 and outside the steel pipe to deburr and polish the outer surface of the steel pipe. During this process, the electric slider can be controlled to move along the electric guide rod 22. The electric guide rod 22 drives the moving table 21 to move. The moving table 21 drives the motor 23 to move. The motor 23 drives the steel pipe to move through the fixture 24. Thus, it can automatically drive the steel pipe to rotate and automatically change the grinding position, further improving the deburring and polishing effect.

[0040] In addition, while deburring and polishing, the liquid inside the liquid storage cylinder 31 is sprayed out through the nozzles on the liquid outlet tray 32 by the water pump inside. Refer to Figures 5 to 6 As shown in the figure, since multiple nozzles are evenly installed along the axis of the liquid outlet tray 32, the sprayed liquid will form an annular water curtain. The water curtain surrounds the grinding block 36 and the steel pipe inside. Thus, during the deburring and polishing of the steel pipe, the water curtain can effectively block the splashing waste chips and sparks, preventing the waste chips and sparks from splashing to the outside and affecting the working environment of the staff. In addition, the water curtain can extinguish the splashing sparks immediately and block them, preventing the sparks from splashing onto flammable objects or components and causing potential safety hazards.

[0041] In addition, the water curtain falls into the interior of the water receiving tank 33 for collection. At the same time, waste chips are collected, which is convenient for the staff to collect, improves the cleanliness of the working environment. At the same time, the water pump installed on the recycling pipe 34 can recycle the liquid inside the water receiving tank 33 back into the interior of the liquid storage cylinder 31 to form a cycle and save water resources;

[0042] During the process of deburring and polishing the outer surface of the steel pipe by the above-mentioned water curtain, refer to Figure 6 As shown, due to the inclined surface design of the flow splitter plate 42, and the top of the flow splitter plate 42 cuts the inner side of the water curtain, the orientation of the water curtain is divided into that the outer side of the water curtain still converges towards the water receiving tank 33, and the inner side of the water curtain splashes along the inclined surface of the flow splitter plate 42. Since the inclined surface of the flow splitter plate 42 faces the steel pipe, part of the liquid on the inner side of the water curtain splashes onto the surface of the steel pipe along the inclined surface of the flow splitter plate 42, which can clean and cool the steel pipe after deburring and polishing. At the same time, the splashing liquid has a certain pressure and can effectively remove the waste chips adhering to the surface of the steel pipe. At the same time, the splashing liquid can cooperate with the water curtain to further intercept and extinguish the sparks generated by grinding, enhancing the safety of the working environment; at the same time, part of the liquid splashing onto the steel pipe will flow down along the surface of the steel pipe and pass through the grinding block 36 and the part of the steel pipe that has not been deburred and polished, which can lubricate and cool the grinding block 36, and pre-clean the part of the steel pipe that has not been deburred and polished to prevent the dust and impurities on the surface from affecting the deburring effect.

[0043] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
