Description

Technical Field

[0001] The invention belongs to the field of steel pipe processing, and particularly relates to an intelligent grinding device for steel pipe processing. Background Art

[0002] Steel pipes are widely used in people's daily life. They can be seen in houses, cars and ships. However, due to the oxidation and rust of the surface of steel pipes during long-term storage, they need to be polished. When using the flap wheel for polishing, the flap wheel, as a consumable, will gradually wear out during use. When the wear reaches a certain degree, its original polishing performance will decrease, which is manifested as reduced polishing efficiency and substandard surface treatment quality. Because its structure is composed of many densely arranged sand blades, it is difficult to restore to its original state after wear. However, for slight local wear, the edge of the emery cloth can be simply repaired to extend the service life.

[0003] Based on the prior art, it is found that after long-term use, grinding debris is easily mixed in the flap wheel of the existing steel pipe grinding equipment, and it is easy to be mixed in the deep gap of the sandpaper in the flap wheel. When the steel pipe grinding equipment is used in an outdoor environment, impurities such as external wind and sand are also easily mixed in the sandpaper of the flap wheel. If the grinding debris and wind and sand are not removed in time, the sandpaper of the flap wheel is easily damaged during long-term working friction of the flap wheel, and gaps are easily formed in the sandpaper of the flap wheel, thereby reducing the grinding effect of the flap wheel on the steel pipe;

[0004] Also, after the flap wheel has been used for a long time, the abrasive cloth in the flap wheel is prone to folding and dispersion. If it is not repaired in time, the deformation of the abrasive cloth will be easily aggravated, which will seriously reduce the service life of the flap wheel and increase production costs.

[0017] (1) The abrasive cloth of the flap wheel is moved by the toggle plate, so that the gap between each adjacent two abrasive cloths in the flap wheel is increased, and air is sucked through the exhaust pipe at the same time, so that the debris and wind sand mixed between the abrasive cloths of the flap wheel are sucked out, and the gap between each adjacent two abrasive cloths in the flap wheel is increased by the toggle plate, so that some debris and wind sand can fall down under the influence of their own gravity, thereby improving the cleaning effect of the flap wheel, thereby improving the grinding effect of the flap wheel on the steel pipe;

[0018] (2) The circular ring, the circular disc and the cover shell are used to block the debris and sand from splashing around, and the circular ring, the circular disc and the cover shell are used to cover the outer side of the flap wheel, so that the pressure at the flap wheel is quickly reduced, thereby improving the cleaning efficiency of the flap wheel;

[0019] (3) The abrasive cloth of the flap wheel is squeezed and contacted with the abrasive cloth of the flap wheel by the toggle plate, so that the abrasive cloth of the flap wheel moves along the surface of the toggle plate, and then the abrasive cloth of the flap wheel is toggled by the toggle plate to repair the abrasive cloth of the flap wheel, thereby reducing the problem of abrasive cloth deformation. The flap wheel rotates on the inner side of the ring and contacts with the inner side of the ring, and is squeezed by the inner side of the ring at the same time, so that the abrasive cloth of the flap wheel is squeezed by the inner side of the ring during the rotation process, thereby making the abrasive cloth of the flap wheel more compact, and the limiting effect of the inner side of the ring makes the abrasive cloth of the flap wheel more neat and uniform, thereby avoiding the phenomenon of folding and dispersion of the abrasive cloth in the flap wheel, thereby prolonging the service life of the flap wheel and reducing the production cost of the enterprise;

[0020] (4) The disc moves so that the ring is no longer closed, thereby increasing the contact between the flap wheel and the air, and the fan is controlled to start operating to take away the heat generated by the flap wheel and the inner side of the ring, thereby cooling the flap wheel, and exhausting air through the exhaust pipe to absorb the heat generated at the flap wheel, further cooling the flap wheel, and the cold water circulation in the two conduits I takes away the heat generated on the ring, thereby cooling the flap wheel and the ring, thereby avoiding the problem of excessive temperature inside the ring causing the material performance of the flap wheel to deteriorate during the repair of the flap wheel;

[0021] (5) Hot air is transported into the annular groove on the disc through the joint, and flows along the annular groove on the disc to the conduit II, and finally blown to the emery cloth in the flap wheel, so that the hot air dries the emery cloth in the flap wheel, so that the water in the flap wheel evaporates, so that the relatively moist rust becomes relatively dry, so that the rust can be separated from the flap wheel, and the emery cloth in the flap wheel is moved by the toggle plate, and then the air is exhausted through the exhaust pipe to absorb the dried rust, thereby achieving deep cleaning of the flap wheel and improving the grinding effect and efficiency of the flap wheel on the steel pipe.

[0043] The disk 216 is provided with a plurality of through slots for heat dissipation.

[0044] When grinding a cylindrical steel pipe: pre-connect the external pump for air delivery to the exhaust pipe 211, then place the cylindrical steel pipe on the steel pipe grinder 1 manually or with an external feeding device, and start the steel pipe grinder 1 to grind and polish the steel pipe. The following will discuss a flap wheel 13. After a long period of use, the flap wheel 13 is easily mixed with grinding debris, that is, the emery cloth of the flap wheel 13 is easily mixed with debris, and when the steel pipe grinder 1 is used in an outdoor environment, external wind and sand are also easily mixed in the emery cloth of the flap wheel 13. If the grinding debris and wind and sand are not removed in time, the emery cloth of the flap wheel 13 is easily damaged after a long period of use, and the flap wheel 13 is easily damaged. Gaps appear in the abrasive cloth, thereby reducing the grinding effect of the flap wheel 13 on the steel pipe. To solve the above problem, the electric slider I 202 is controlled to move along the electric slide rail I 201. The movement of the electric slider I 202 drives the fixed plate 203 to move. The movement of the fixed plate 203 drives the electric slide rail II 204 to move, thereby driving all the connected components to move, so that the ring 210 is close to the flap wheel 13. At the same time, the electric slider II 205 is controlled to move along the electric slide rail II 204, thereby driving the electric actuator 206 and the connecting frame 207 to move, and the electric actuator 206 is controlled to start and drive the connecting frame 207 to move. The movement of the connecting frame 207 drives the arc plate 208 to move, thereby driving all the connected components to move, so that the ring 210 moves to the outside of the flap wheel 13, as shown in FIG. Figure 1 As shown, at the same time, the electric slider III 213 is controlled to start moving along the electric slide rail III 212, the movement of the electric slider III 213 drives the connecting rod 214 to move, the movement of the connecting rod 214 drives the fixing ring 215 to move, the movement of the fixing ring 215 drives the disc 216 to move, the movement of the disc 216 drives the toggle plate 217 to move, and then the toggle plate 217 moves to the inner side of the ring 210 and contacts the sandpaper of the flap wheel 13. At this time, the steel pipe grinder 1 is controlled to operate to rotate the flap wheel 13, as shown in FIG. Figure 3 As shown, the flap wheel 13 rotates counterclockwise from the front to the back, and the steel pipe grinder 1 is in a low-speed rotation state, so that the flap wheel 13 rotates counterclockwise at a low speed, so that the sandpaper of the flap wheel 13 touches the toggle plate 217 when rotating at a low speed, and is squeezed by the toggle plate 217, and then the sandpaper of the flap wheel 13 is toggled by the toggle plate 217, so that the gap between each adjacent two sandpapers in the flap wheel 13 is increased, and at the same time, the external pump is controlled to start to exhaust air through the exhaust pipe 211, so that the debris and wind sand mixed between the sandpapers of the flap wheel 13 are sucked out, and the gap between each adjacent two sandpapers in the flap wheel 13 is increased by the toggle plate 217, so that part of the debris and wind sand can fall down under the influence of their own gravity, thereby improving the cleaning effect of the flap wheel 13, thereby improving the grinding effect of the flap wheel 13 on the steel pipe;

[0045] And through the setting of the ring 210 and the disk 216, the ring 210 and the disk 216 cooperate with the cover shell 12 to cover the outside of the flap wheel 13, and then when the exhaust pipe 211 is sucking air to absorb debris, the shielding of the ring 210, the disk 216 and the cover shell 12 reduces the debris and sand from splashing everywhere, and the ring 210 and the disk 216 cooperate with the cover shell 12 to cover the outside of the flap wheel 13, so that the pressure at the flap wheel 13 is quickly reduced, thereby improving the cleaning efficiency of the flap wheel 13.

[0046] Embodiment 2

[0047] Based on the first embodiment, Figure 8 As shown, a repair system is also included; the repair system is connected to the outside of the ring 210; the repair system includes a water bag 301 and a catheter I 302; two water bags 301 are fixedly connected to the outside of the ring 210, and all the water bags 301 are connected; each water bag 301 is fixedly connected and connected to a catheter I 302; all catheters I 302 pass through the arc plate 208 and the connecting frame 207.

[0048] The disk 216 also includes a fan 303 ; the fan 303 is fixedly connected to the middle of the disk 216 .

[0049] When repairing the flap wheel 13: pre-connect the external pump for water delivery to the conduit Ⅰ302, and allow cold water to circulate in the two conduits Ⅰ302. After the flap wheel 13 has been used for a long time, the abrasive cloth in the flap wheel 13 is prone to folding and dispersion. If it is not repaired in time, the deformation of the abrasive cloth will be easily aggravated, thereby seriously reducing the service life of the flap wheel 13, increasing the production cost, and reducing the grinding effect of the flap wheel 13 on the steel pipe. When the abrasive cloth of the flap wheel 13 touches the toggle plate 217 during low-speed rotation, the toggle plate 217 squeezes the abrasive cloth of the flap wheel 13 and contacts the abrasive cloth of the flap wheel 13, thereby moving the abrasive cloth of the flap wheel 13 along the surface of the toggle plate 217, and then toggling the abrasive cloth of the flap wheel 13 through the toggle plate 217. When the abrasive cloth of the flap wheel 13 is Figure 4In the state shown, since the arrangement of the abrasive cloth of the flap wheel 13 is relatively close, if the abrasive cloth of the flap wheel 13 is slightly bent and squeezed by the abrasive cloth of the adjacent flap wheel 13, it will not be able to return to the flat state normally. Therefore, the bent part of the abrasive cloth of the flap wheel 13 is pushed outward by the toggle plate 217 to repair the abrasive cloth of the flap wheel 13 and reduce the deformation problem of the abrasive cloth. Then the electric slider III 213 is controlled to start moving and resetting along the electric slide rail III 212, thereby driving all the connected parts to move and reset, so that the toggle plate 217 is separated from the flap wheel 13 and no longer contacts the flap wheel 13. Then the external pump is controlled to start operating to transport water into the two water bags 301 through the two conduits I 302. At this time, the water will be retained in the two water bags 301. When the water becomes more and more, the water will squeeze the two water bags 301, causing the volume of the two water bags 301 to expand, and the outer annular surfaces of the two water bags 301 will The two expanded water bags 301 press against the inner side of the cover shell 12, so that the ring 210 shrinks toward the center of the flap wheel 13. The shrinkage of the ring 210 stretches all the springs 209, so that the inner side of the ring 210 contacts the sandpaper of the flap wheel 13. At this time, the steel pipe grinder 1 is controlled to operate so that the flap wheel 13 rotates, so that the flap wheel 13 rotates on the inner side of the ring 210 and contacts the inner side of the ring 210, and is squeezed by the inner side of the ring 210, so that the sandpaper of the flap wheel 13 is squeezed by the inner side of the ring 210 during the rotation process, so that the sandpaper of the flap wheel 13 becomes more compact, and the sandpaper of the flap wheel 13 becomes more neat and uniform through the limiting effect of the inner side of the ring 210, so as to avoid the sandpaper in the flap wheel 13 from folding and dispersion, thereby improving the service life of the flap wheel 13 and reducing the production cost of the enterprise;

[0050] In addition, during the repair process of the flap wheel 13, the flap wheel 13 will contact the inner side of the ring 210 when rotating, causing the temperature of the inner side of the ring 210 to rise rapidly, which may easily lead to the degradation of the material properties of the flap wheel 13, change the physical and chemical properties of the material of the flap wheel 13, and cause the hardness, strength or toughness to decrease, thereby affecting the grinding effect and service life of the flap wheel 13. In order to solve the above problem, in the process of the toggle plate 217 moving away from the flap wheel 13, the disc 216 is synchronously moved away from the ring 210, so that the disc 216 moves and no longer closes the ring 210, thereby increasing the contact between the flap wheel 13 and the air, and controlling the fan 303 to start the operation. The heat generated by the flap wheel 13 and the inner side of the ring 210 is taken away, thereby cooling the flap wheel 13. At the same time, the external pump is controlled to start to exhaust air through the exhaust pipe 211, thereby absorbing the heat generated at the flap wheel 13, further cooling the flap wheel 13, and controlling another external pump to start and operate so that the cold water in the two conduits Ⅰ302 circulates, thereby taking away the heat generated on the ring 210 through the two conduits Ⅰ302, thereby cooling the flap wheel 13 and the ring 210, thereby avoiding the problem of excessively high temperature on the inner side of the ring 210 causing the material properties of the flap wheel 13 to deteriorate during the repair of the flap wheel 13.

[0051] Embodiment 3

[0052] Based on the second embodiment, according to Figure 9-11 As shown, it also includes a chip removal system; the chip removal system includes a motor 401, a spur gear 402, a gear ring 403, a fixed rod 404, a retaining ring 405, a joint 406 and a conduit II 407; the motor 401 is installed on the connecting rod 214; the output shaft of the motor 401 passes through the connecting rod 214 and is fixedly connected to the spur gear 402; the gear ring 403 is fixedly connected to the disk 216; the gear ring 403 is meshed with the spur gear 402; two fixed rods 404 are fixedly connected to the connecting rod 214; all the fixed rods 404 are fixedly connected to the retaining ring 405, and the disk 216 is provided with an annular groove, and the retaining ring 405 is circumferentially slidably connected to the annular groove; the lower part of the retaining ring 405 is fixedly connected to the joint 406; the lower part of the disk 216 is fixedly connected to the conduit II 407; the conduit II 407 is connected to the annular groove on the disk 216; the conduit II 407 is fixedly connected to the toggle plate 217.

[0053] A filter is provided at each air outlet of the conduit II 407 to prevent debris from falling into the conduit II 407 .

[0054] When deep cleaning the flap wheel 13: pre-connect the other external pump machine connection joint 406. When the flap wheel 13 is grinding and polishing the steel pipe, the steel pipe is placed in a humid environment for a long time, causing the rust on the outer wall of the steel pipe to be relatively moist. As a result, the relatively moist rust will be transferred to the flap wheel 13 during the grinding process, and will be mixed between the sandpaper of the flap wheel 13, thereby weakening the grinding effect of the flap wheel 13 on the steel pipe, resulting in a decrease in grinding efficiency. The same working principle as above is used to move the toggle plate 217 to the inner side of the ring 210 and contact the sandpaper of the flap wheel 13. When the steel pipe grinder 1 stops operating, the flap wheel 13 stops rotating, and then the motor 401 is controlled to start, the output shaft of the motor 401 rotates to drive the spur gear 402 to rotate at a low speed, the spur gear 402 rotates to drive the gear ring 403 to rotate, the gear ring 403 rotates to drive the disc 216 to rotate, the disc 216 rotates to drive the toggle plate 217 to rotate, and then all the sandpapers in the flap wheel 13 are sequentially toggled by the toggle plate 217 rotating at a low speed, and at the same time, another external pump is controlled to transport hot air into the annular groove opened on the disc 216 through the joint 406, and the hot air flows along the annular groove opened on the disc 216 to the conduit Ⅱ407, and finally blows to the abrasive cloth in the flap wheel 13. When the flap wheel 13 is repaired, the flap wheel 13 will rub against the inner side of the ring 210 when it rotates to generate high temperature. When the flap wheel 13 rubs against the inner side of the ring 210, most of the outer edges of the abrasive cloth in the flap wheel 13 rub against the inner side of the ring 210, so that there is still moisture in the middle area of ​​the abrasive cloth in the flap wheel 13. Therefore, it is necessary to use the conduit Ⅱ407 to transport hot air to dry the abrasive cloth in the flap wheel 13, so that the hot air is used to dry the abrasive cloth in the flap wheel 13. The moisture in the flap wheel 13 evaporates, so that the relatively moist rust becomes relatively dry, so that the rust can be separated from the flap wheel 13. Then, the toggle plate 217 is rotated and reset, and the motor 401 is controlled to stop operating. At this time, the toggle plate 217 will stop in place and remain motionless. Then, the flap wheel 13 is rotated according to the same working principle as above, and the sandpaper in the flap wheel 13 is toggled by the toggle plate 217, and then the air is exhausted through the exhaust pipe 211 to absorb the dried rust, thereby achieving deep cleaning of the flap wheel 13 and improving the grinding effect and grinding efficiency of the flap wheel 13 on the steel pipe.

[0055] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
