Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, in particular to a steel pipe polishing and cleaning device. Background Art

[0002] The steel pipe polishing and cleaning device can improve the surface quality, dimensional accuracy, corrosion resistance and service life of the steel pipe by polishing and cleaning the surface of the steel pipe, and at the same time ensure that the steel pipe meets the industry standards and customer requirements.

[0003] Although the current technology has many advantages, the disadvantage of the current technology is that when polishing the steel pipe, because the polishing wheel rotates very fast, the impurities polished off will be thrown out under the action of centrifugal force, and this situation usually brings sparks. When the sparks fall on flammable items, it may trigger a fire, endangering the physical health of the staff and the normal operation of the equipment. At the same time, during the polishing process, the polishing wheel rubs against the surface of the steel pipe to generate static electricity, which will accumulate on the polishing wheel to form a charged state. The charged polishing wheel will attract small metal particles or other impurities, which will affect the flatness of the surface of the polishing wheel, make scratches on the product surface, and reduce the polishing quality.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figures 1-4 The utility model provides a technical solution: a steel pipe polishing and cleaning device, comprising: a base 1, characterized in that: a support frame 2 is fixedly connected to the top of the base 1, two support plates 3 are fixedly connected to the outer surface of the support frame 2, a motor 4 and a motor 2 5 are fixedly connected to the top of the two support plates 3, the motor 4 is provided with a rotating shaft 6 through an output shaft, two pulleys 7 are fixedly installed on the outer surface of the rotating shaft 6, a rotating shaft 2 13 is provided on the outer surface of the motor 2 5 through the output shaft, two cams 14 are fixedly connected to the outer surface of the rotating shaft 2 13, and the two cams 14 are fixedly connected to the side away from the rotating shaft 2 13 There is a fixed rod 15, and a rotating sleeve 16 is provided on the outer surface of the fixed rod 15. A polishing wheel 18 and two pulleys 17 are fixedly installed on the outer surface of the rotating sleeve 16. The outer surfaces of the two pulleys 17 are provided with a transmission belt 12. The outer surfaces of the two pulleys 17 and the pulley 2 17 are provided with a tension control mechanism. The outer surface of the fixed rod 15 is provided with a magnetic mechanism, which ensures the flatness of the surface of the polishing wheel 18, ensures the polishing quality to a certain extent, protects the working environment, reduces the probability of fire to a certain extent, ensures the health of the staff, and creates conditions for the normal operation of the equipment.

[0019] like Figure 4 As shown, the magnetic mechanism includes an electromagnet 19, which is fixedly connected to the outer surface of the fixed rod 15. A connecting wire 20 is provided on the outer surface of the electromagnet 19. A shielding block 21 is fixedly connected to the side of the fixed rod 15 close to the electromagnet 19. The connecting wire 20 is movably embedded in the inner surface of the fixed rod 15. The shielding block 21 is made of metal, which can effectively guide the magnetic field, thereby shielding the attraction of the electromagnet 19 to impurities and making the impurities separate from the polishing wheel 18.

[0020] As Figure 3 shown, the tension control mechanism includes a plurality of notches 8 which are opened on the outer surfaces of two pulley 1s 7 and pulley 2s 17. The inner surfaces of the plurality of notches 8 are fixedly connected with springs 10. The inner surfaces of the plurality of springs 10 are movably embedded with telescopic rods 9. The outer surfaces of the plurality of telescopic rods 9 are connected with rubber pads 11. The plurality of telescopic rods 9 are movably embedded in the inner surfaces of two pulley 1s 7 and pulley 2s 17. The springs 10 can provide power for the reverse movement of the rubber pads 11, so that the rubber pads 11 are always in contact with the transmission belt 12.

[0021] As Figure 2 shown, two transmission belts 12 are arranged on the outer surfaces of two pulley 2s 17. The rotating shaft 1 6 and the rotating shaft 2 13 are movably embedded in the inner surface of the support frame 2. The rotating shaft 1 6 can transmit the power of the motor 1 4 to the pulley 1 7, so that the pulley 1 7 rotates.

[0022] Working principle: This device is a steel pipe polishing and cleaning device. When in use, connect the connecting wire 20 to supply power to the electromagnet 19, so that the electromagnet 19 generates a magnetic field. Place the steel pipe to be polished on the base 1, start the auxiliary electrical components of the base 1 to make the steel pipe move slowly on the base 1, and then start the second motor 5. The second motor 5 is attached with a stepper. The second motor 5 drives the second rotating shaft 13 to rotate through the output shaft. The second rotating shaft 13 drives the fixed rod 15 to make an arc motion with the second rotating shaft 13 as the center, thereby indirectly making the polishing wheel 18 closely fit the steel pipe to be polished. Then start the first motor 4. The first motor 4 drives the first rotating shaft 6 to rotate through the output shaft. The first rotating shaft 6 indirectly drives the transmission belt 12 to rotate through the first pulley 7. The transmission belt 12 indirectly drives the rotating sleeve 16 to make a circular motion with the fixed rod 15 as the center through the second pulley 17. The rotating sleeve 16 drives the polishing wheel 18 to rotate to polish the steel pipe. Because the electromagnet 19 is close to the steel pipe to be polished, when polishing the steel pipe, most of the impurities polished off are metal components. Therefore, the impurities carry charges and will be attracted by the electromagnet 19, causing the impurities to stay on the surface of the polishing wheel 18 and rotate with the polishing wheel 18. When the impurities move upward with the polishing wheel 18, at this time, due to the effect of the shielding block 21, there is no longer a magnetic field here, so the impurities will no longer be attracted by the magnetic force. At this time, the high-speed rotation of the polishing wheel 18 will cause the impurities to be thrown out by the centrifugal force, so that the impurities are separated from the polishing wheel 18. At this time, the impurities will also be blocked by the protective cover and will not splash around, but will fall vertically into the collection tank. The protective cover and the collection tank are prior arts and will not be elaborated too much. Because the second pulley 17 will move, the transmission belt 12 will undergo slight deformation, so the force of the transmission belt 12 on the rubber pad 11 will also change. The spring 10 in the groove 8 can stretch or contract with the change of the force of the transmission belt 12, so that the rubber pad 11 on the telescopic rod 9 fits the transmission belt 12, and the situation that the transmission belt 12 falls off due to the movement of the second pulley 17 will not occur. The cooperation of the support frame 2 and the support plate 3 can support the main structure of the device.

[0023] The above are only the preferred embodiments of the present invention, and do not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
