Technical Field

[0002] Grinding machine is a common equipment used to sharpen various knives and tools. It is also used for grinding, deburring and cleaning ordinary small parts. It is mainly composed of a base, a grinding wheel, an electric motor or other power source, a bracket, a protective cover and a water supply. It can be divided into hand-held grinding machines, vertical grinding machines, hanging grinding machines, desktop grinding machines, etc. Grinding machine is a kind of mechanical processing tool, which is used in many industries. Because the tool is worn and blunt or the tool is damaged and loses its cutting ability, the tool must be sharpened on the grinding wheel to restore its cutting ability.

[0003] One of the surface defects of steel is that the ends of cold-cut, hot-sawed or flame-cut steel have uneven burrs, and there is excess metal extruded at the weld when welding pipes. Generally, products are allowed to have burrs of a certain height, and the internal and external burrs of welded pipes must be scraped off. When ordinary grinders grind the end faces of metal pipes, the beveled surfaces on the end faces of the metal pipes cannot be fully polished, which will cause safety hazards to the subsequent use of the pipes and cannot meet actual needs. Summary of the invention

[0017] The other end of the second grinding wheel rod is equipped with a grinding mechanism, which is used to grind the pipeline.

[0018] By making the detection roller contact the end face of the metal pipe first, the detection rollers on both sides will determine whether the edge of the end face of the metal pipe is beveled. If there is no bevel, the operation panel will move forward to make the detection rollers on both sides deflect inwardly by a certain angle, driving the connecting plate and the pulling plate to rotate, and the connecting plate drives the connecting seat to move forward, and the connecting seats on both sides respectively drive the second grinding wheel rod and the first grinding wheel rod to deflect inwardly by a certain angle, thereby achieving the effect of grinding edge burrs.

[0022] A cooling mechanism is installed on the upper surface of the boss, and the cooling mechanism is used to cool the surface of the pipeline.

[0023] The end face of the metal tube is continuously polished by the first grinding wheel roller and the second grinding wheel roller. The deflection of the second grinding wheel rod and the first grinding wheel rod causes the first grinding wheel roller and the second grinding wheel roller to deflect inwardly by a certain angle, thereby removing the burrs on the edge and achieving the effect of removing the burrs on the grinding surface. There is a bevel on the edge of the end face of the metal tube. The first grinding wheel roller and the second grinding wheel roller are deflected inwardly by a certain angle, and the detection roller is close to the bevel on the end face edge of the metal tube, thereby achieving the effect of polishing the bevel on the end face edge of the metal tube.

[0024] Furthermore, due to the design of the first connecting piece, the cross rod and the second connecting piece, the first grinding wheel rod and the second grinding wheel rod are coupled so that the first grinding wheel rod rotates along with the second grinding wheel rod, achieving the effect of transmitting power even when deflected at a certain angle.

During the continuous rotation of the first grinding wheel roller and the second grinding wheel roller, due to the action of centrifugal force, the conical cavity causes water to gather at the bottom of the conical cavity, most of the water flows out through the first drainage hole, and a small amount of water flows out through the second drainage hole. The outflowing water can cool the end face of the metal pipe, thereby protecting the metal pipe.

[0027] As can be seen from the above, the grinding wheel machine for pipeline production provided by the present invention has the following technical effects.

[0028] 1. By designing the first grinding wheel roller and the second grinding wheel roller, and the deflection of the second grinding wheel rod and the first grinding wheel rod, the first grinding wheel roller and the second grinding wheel roller are also deflected inwardly by a certain angle, so that the burrs on the edge are removed cleanly, and the burrs on the grinding surface are removed. There is a bevel on the end face edge of the metal pipe. The first grinding wheel roller and the second grinding wheel roller are deflected inwardly by a certain angle, and the detection roller is close to the bevel on the end face edge of the metal pipe, so as to grind the bevel on the end face edge of the metal pipe.

[0029] 2. Make the detection roller contact the end face of the metal tube first, and then the detection rollers on both sides will bend according to whether the edge of the end face of the metal tube is beveled. If there is no bevel, the operation panel will move forward to make the detection rollers on both sides rotate inwards by a certain angle, driving the connecting plate and the pulling plate to rotate. The connecting plate drives the connecting seat to move forward, and the connecting seats on both sides respectively drive the second grinding wheel rod and the first grinding wheel rod to rotate inwards by a certain angle, so as to achieve the effect of grinding edge burrs.

[0030] 3. By rotating the threaded rod, the slider is driven to slide forward, so that the equipment is close to one end of the metal pipe, and the operating panels on both sides slide forward respectively. According to the different bevel angles of the inner edge and outer side of the end face of the metal pipe, the rotating plate rotates to different angles to adapt to the bevel angles of the inner edge and outer side of the end face of the different metal pipes.

[0031] 4. A release handle is designed, and the release handle can be turned to separate the release handle and the rotating support frame, so that the rotating support frame rotates, so that the metal pipe slides off the rotating support frame, and the reset spring rebounds to return the rotating support frame to its original position. The rotating support frame is supported by the blocking block, and the release handle is turned to clamp the rotating support frame, so that the position of the rotating support frame is fixed, which achieves the effect of fast material change.

[0054] A grinding mechanism is installed at the other end of the second grinding wheel rod 35, and the grinding mechanism is used to grind the pipeline.

[0055] In this embodiment, the operating panel 22 moves forward, and the detection roller 31 first contacts the end face of the metal tube 9. The detection rollers 31 on both sides are adjusted according to whether the edge of the end face of the metal tube 9 is beveled. If there is no bevel, the operating panel 22 moves forward, so that the detection rollers 31 on both sides are deflected inwardly by a certain angle, driving the connecting plate 27 and the pulling plate 28 to rotate, and the connecting plate 27 drives the connecting seat 37 to move forward. The connecting seats 37 on both sides respectively drive the second grinding wheel rod 35 and the first grinding wheel rod 32 to deflect inwardly by a certain angle, thereby achieving the effect of grinding edge burrs.

[0056] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, the driving mechanism includes a mounting plate 26 fixedly connected to one side of the intermediate seat 36, one end of the second grinding wheel rod 35 is fixedly connected to a driven pulley 24, one side of the mounting plate 26 is fixedly connected to a grinding motor 16, one end of the output shaft of the grinding motor 16 is fixedly connected to a driving wheel 23, and a belt 25 is arranged between the driving wheel 23 and the driven pulley 24.

[0057] In this embodiment, the grinding motor 16 rotates to drive the belt 25, so that the driven pulley 24 drives the second grinding wheel rod 35 to rotate, so that the second grinding wheel rod 35 and the first grinding wheel rod 32 can also transmit power when they deflect inward.

[0058] Reference Figure 1 , Figure 6 , Figure 7 and Figure 8 In a preferred embodiment, the grinding mechanism includes a first grinding wheel roller 33 fixedly connected to one end of the first grinding wheel rod 32, and one end of the second grinding wheel rod 35 is fixedly connected to the second grinding wheel roller 34.

One end of the first grinding wheel rod 32 is respectively fixedly connected to two first connecting pieces 44, and one end of the second grinding wheel rod 35 is respectively fixedly connected to two second connecting pieces 46. One end of the second grinding wheel rod 35 is plugged with a guide pipe 47, and one side of the first connecting piece 44 is rotatably connected to a cross rod 45. The first grinding wheel roller 33 and the second grinding wheel roller 34 are fixedly connected to a plurality of grinding sheets 43 at the edges of the opposite ends.

[0059] A cooling mechanism is installed on the upper surface of the boss, and the cooling mechanism is used for cooling the surface of the pipeline.

[0060] In this embodiment, if the edge of the end face of the metal tube 9 is beveled, since the surfaces of the first grinding wheel roller 33 and the second grinding wheel roller 34 are inlaid with grindstone particles, the end face of the metal tube 9 is continuously polished, and the deflection of the second grinding wheel rod 35 and the first grinding wheel rod 32 causes the first grinding wheel roller 33 and the second grinding wheel roller 34 to also deflect inward by a certain angle, so that the burrs on the edge are removed cleanly, thereby achieving the effect of removing burrs on the grinding surface. There is a bevel on the edge of the end face of the metal tube 9, and the first grinding wheel roller 33 and the second grinding wheel roller 34 are deflected inward by a certain angle, and the detection roller 31 is close to the bevel on the end face edge of the metal tube 9, so as to achieve the effect of polishing the bevel on the end face edge of the metal tube 9.

[0061] Furthermore, due to the design of the first connecting piece 44, the cross rod 45 and the second connecting piece 46, the first grinding wheel rod 32 and the second grinding wheel rod 35 are coupled so that the first grinding wheel rod 32 rotates along with the second grinding wheel rod 35, achieving the effect of deflecting a certain angle while still being able to transmit power.

[0062] It is also necessary to explain that, since the grinding sheet 43 is a flexible material containing abrasive particles, the grinding sheet 43 also has a grinding function. When the first grinding wheel roller 33 and the second grinding wheel roller 34 deflect inward, the multiple grinding sheets 43 do not interfere with each other. Due to the bevel design of the grinding sheet 43, the surface between the first grinding wheel roller 33 and the second grinding wheel roller 34 can also be polished.

[0063] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 In a preferred embodiment, the cooling mechanism includes a mounting frame 15 fixedly connected to the upper surface of the boss, the top of the mounting frame 15 is fixedly connected to a water tank 8, the bottom of the water tank 8 is plugged with a water pipe 38, the pre-tightening rod 18 slides in the slide groove 19, the threaded rod 17 is threadedly connected to the slider 12, the pulling plate 28 is rotatably connected to one end of the return rod 39, and the grinding sheets 43 are spaced a certain distance apart.

[0064] In this embodiment, during the grinding process, water is injected into the water tank 8, and the water enters the interior of the first grinding wheel rod 32 through the water guide pipe 38 and the connecting seat 37, passes through the conical cavity in the first grinding wheel roller 33, and enters the conical cavity in the second grinding wheel roller 34 through the guide pipe 47 and the water guide hole 50. During the continuous rotation of the first grinding wheel roller 33 and the second grinding wheel roller 34, due to the action of centrifugal force, the conical cavity causes water to gather at the bottom of the conical cavity, most of the water flows out through the first drainage hole 48, and a small amount of water flows out through the second drainage hole 49. The outflowing water can cool the end face of the metal tube 9, thereby protecting the metal tube 9.

[0065] Working principle: When in use, the metal pipe 9 is placed on the fixed support frame 10 and the rotating support frame 11 through the lifting equipment. After the grinding is completed, the release handle 5 can be turned to separate the release handle 5 and the rotating support frame 11, so that the rotating support frame 11 can be rotated, so that the metal pipe 9 slides off the rotating support frame 11, and the reset spring 4 rebounds to make the rotating support frame 11 return to its original position. The rotating support frame 11 is resisted by the stop block 6, and the release handle 5 is turned to clamp the rotating support frame 11 to fix the position of the rotating support frame 11, and the second metal pipe 9 is placed again to perform the end face grinding operation. When performing the end face grinding operation, the transmission motor 7 is started to rotate the threaded rod 17, driving the slider 12 to slide forward, so that the equipment is close to one end of the metal pipe 9, and the operations on both sides are performed. The plates 22 slide forward respectively. According to the different bevel angles of the inner edge and the outer side of the end face of the metal tube 9, the rotating plate 13 rotates to different angles to adapt to the bevel angles of the inner edge and the outer side of the end face of the metal tube 9. The operating plate 22 moves forward and squeezes the preload spring 21, so that the operating plates 22 on both sides have preload force to prevent the rotating plate 13 from rotating at will. The function of the slide groove 19 is to give the connecting block 20 horizontal freedom. The operating plate 22 moves forward, and the detection roller 31 contacts the end face of the metal tube 9 first. The detection rollers 31 on both sides are based on whether the edge of the end face of the metal tube 9 is beveled. If there is no bevel, burrs will appear on the edge of the end face of the metal tube 9 after being polished by the first grinding wheel roller 33 and the second grinding wheel roller 34. The operating plate 22 moves forward so that the detection rollers on both sides The connecting plate 27 drives the connecting seat 37 to move forward, and the connecting seats 37 on both sides drive the second grinding wheel rod 35 and the first grinding wheel rod 32 to deflect inwardly by a certain angle. Since the surfaces of the first grinding wheel roller 33 and the second grinding wheel roller 34 are inlaid with grindstone particles, the end surface of the metal pipe 9 is continuously polished. The deflection of the second grinding wheel rod 35 and the first grinding wheel rod 32 causes the first grinding wheel roller 33 and the second grinding wheel roller 34 to deflect inwardly by a certain angle, and the burrs on the edge are removed cleanly, which has the effect of removing the burrs on the grinding surface. There is a bevel on the end surface edge of the metal pipe 9. The first grinding wheel roller 33 and the second grinding wheel roller 34 are deflected inwardly by a certain angle, and the detection roller 31 is close to the metal pipe 9. The bevel on the edge of the end face has the effect of grinding the bevel on the edge of the end face of the metal tube 9. The power of the first grinding wheel roller 33 and the second grinding wheel roller 34 is provided by the grinding motor 16. The grinding motor 16 rotates to drive the belt 25, so that the driven pulley 24 drives the second grinding wheel rod 35 to rotate. Due to the design of the first connecting piece 44, the cross rod 45 and the second connecting piece 46, the first grinding wheel rod 32 and the second grinding wheel rod 35 are coupled to make the first grinding wheel rod 32 rotate with the second grinding wheel rod 35, which has the effect of deflecting a certain angle and still transmitting power. Since the grinding sheet 43 is a flexible material containing grinding particles, the grinding sheet 43 also has a grinding function. When the first grinding wheel roller 33 and the second grinding wheel roller 34 deflect inward, the multiple grinding sheets 43 do not interfere with each other.Due to the bevel design of the grinding sheet 43, the surface between the first grinding wheel roller 33 and the second grinding wheel roller 34 can also be polished. During the grinding process, water is injected into the water tank 8, and the water enters the interior of the first grinding wheel rod 32 through the water guide pipe 38 and the connecting seat 37, passes through the conical cavity in the first grinding wheel roller 33, and enters the conical cavity in the second grinding wheel roller 34 through the guide pipe 47 and the water guide hole 50. During the continuous rotation of the first grinding wheel roller 33 and the second grinding wheel roller 34, due to the centrifugal force, the conical cavity causes the water to gather at the bottom of the conical cavity, and most of the water flows out through the first drainage hole 48, and a small amount of water flows out through the second drainage hole 49. The outflowing water can cool the end surface of the metal pipe 9, thereby protecting the metal pipe 9.
