According to the metal pipe grinding device, a metal pipe is driven to move obliquely downwards through a transfer assembly, then a moving quartz roller A drives a gear to be meshed with teeth, the quartz roller A drives the metal pipe to rotate, a moving extrusion plate extrudes one end of a plate C, the plate C drives a connecting rod and a sliding plate to move together, grinding liquid in a liquid cavity is sprayed to the surface of the metal pipe, and the metal pipe is ground. As the metal pipe rotates during movement, the surface of the metal pipe can be filled with grinding liquid, when an extrusion plate is separated from one end of a plate C, the plate C resets to extrude gas in a gas cavity, so that the gas is blown to the metal pipe, and grinding particles on the surface of the metal pipe are further uniformly distributed on the surface of the metal pipe; therefore, the polishing effect of the metal pipe is improved.

[0004] In the above patent, the metal tube is directly polished during grinding. Since the impurity layer on the outer surface of the metal tube varies in size, when the metal tube is ground, the area with more impurities can be ground by the grinding tool, but due to the lack of conditions to promote full contact between the grinding tool and the surface of the metal tube, the grinding speed is slow; while in the area with fewer impurities, it is difficult for the grinding tool to fully exert its grinding effect and these areas cannot be effectively polished, resulting in reduced effect of metal tube polishing.

[0040] A bottom groove 221 is provided on the upper surface of the inclined plate 22, and side grooves 222 are provided on both sides of the inner wall of the bottom groove 221.

The horizontal plate 234 is provided with two groups, and a wide hole 236 is opened on one side of the two groups of horizontal plates 234. A horizontal rod 2361 is arranged inside the wide hole 236, and a gear 2362 is sleeved on the outer surface of the horizontal rod 2361.

The threaded rod A227 is used to convey the connecting plate 231 to move the metal tube. Then, when the connecting plate 231 moves, the quartz roller A2363 will rotate with the metal tube because of the meshing of the gear 2362 and the teeth 224. Combined with the grinding liquid sprayed by the spray assembly 25, the surface of the metal tube can be filled with the grinding liquid, thereby improving the subsequent polishing effect of the metal tube.

[0042] A circular groove 235 is also provided on one side of the horizontal plate 234, and fine holes 237 are opened on the inner wall of the circular groove 235. A vertical plate 238 is fixedly installed on the upper surface of the horizontal plate 234, and an extrusion plate 239 is fixedly installed on the upper surface of the vertical plate 238. A scraper 232 is fixedly installed on the lower surface of the connecting plate 231. When the connecting plate 231 descends, the grinding liquid inside the spray assembly 25 can be squeezed through the extrusion plate 239, thereby spraying the grinding liquid. Subsequently, the grinding liquid on the surface of the bottom groove 221 can be scraped into the collection box 228 through the scraper 232 to collect the grinding liquid.

[0043] The baffle 24 is located between the two groups of horizontal plates 234. A slot 241 is provided on one side of the baffle 24. A quartz roller B243 is movably provided on the inner wall of the slot 241. A motor B242 is provided at one end of the baffle 24. A rotating rod is provided at the output end of the motor B242. One end of the rotating rod is fixedly connected to one end of the baffle 24. The motor B242 is fixedly connected to the circular slot 235. The rotating rod is movably connected to the fine hole 237. The baffle 24 can prevent the metal tube from falling off the surface of the quartz roller A2363 when the metal tube is transported. The motor B242 can rotate the baffle 24 to allow the metal tube to detach from the surface of the quartz roller A2363.

[0044] The spray assembly 25 includes a top plate 251 fixedly mounted on one side of the conveyor 1, an air cavity 252 and a liquid cavity 254 opened inside the top plate 251, an air port 2521 opened at the bottom of the air cavity 252, and an air inlet pipe 253 fixedly mounted on the top of the air cavity 252 and the liquid cavity 254, an air inlet check valve is arranged inside the air inlet pipe 253 at the top of the air cavity 252, an air outlet check valve is arranged inside the air inlet pipe 253 at the top of the liquid cavity 254, a tension spring A256 is fixedly mounted on the inner wall of the air cavity 252, a C plate 255 is fixedly mounted on one end of the tension spring A256, and a connecting rod 257 is fixedly mounted on the inner wall of the C plate 255 A slide plate 258 is fixedly installed at one end of the connecting rod 257. The connecting rod 257 and the slide plate 258 are located inside the liquid chamber 254. The movement of the connecting plate 231 can allow the extrusion plate 239 to move to one end with the C plate 255, so that the slide plate 258 squeezes the liquid inside the liquid chamber 254, so that the liquid inside the liquid chamber 254 is sprayed onto the surface of the metal tube, and then the C plate 255 can be reset by the tension spring A256. Subsequently, when the tension spring A256 is reset, the gas inside the air chamber 252 can be squeezed out through the C plate 255, so that the gas is sprayed toward the metal tube, so that the abrasive particles on the surface of the metal tube are evenly distributed.

[0045] A reciprocating screw rod 2541 is fixedly installed on the inner wall of the liquid chamber 254, and a liquid inlet pipe 2542 is also arranged on the top of the liquid chamber 254. A liquid port 2543 is opened at the bottom of the reciprocating screw rod 2541, and a plate groove 2544 and a receiving groove 2545 are opened on the inner wall of the liquid port 2543. An L plate 2546 is movably arranged inside the plate groove 2544, and a magnet B2547 is fixedly installed on one side of the L plate 2546, and a fine plate 2548 is fixedly installed on the other side of the L plate 2546. The fine plate 2548 is slidably connected to the receiving groove 2545, and a tension spring B2549 is fixedly installed on one side of the fine plate 2548, and one end of the tension spring B2549 is fixedly connected to the inner wall of the receiving groove 2545. The grinding liquid inside the liquid chamber 254 can be sprayed through the liquid port 2543, and the liquid inside the liquid chamber 254 can be indirectly sprayed through the L plate 2546.

[0046] A collar 2581 is movably provided on the inner wall of the slide plate 258, a blade 2582 is sleeved on the outer surface of the collar 2581, a slide bar 2583 is provided on the inner wall of the collar 2581, a push plate 2584 is fixedly installed on one side of the slide plate 258, a through groove 2585 is provided on the upper surface of the push plate 2584, a magnet A2586 is fixedly installed on one end of the push plate 2584, the magnet A2586 and the magnet B2547 are magnetically attracted to each other, the inner wall of the collar 2581 is adapted to the reciprocating screw rod 2541, the slide bar 2583 is slidably connected with the thread on the outer surface of the reciprocating screw rod 2541, and the movement of the slide plate 258 allows the magnet A2586 and the magnet B2547 to be attracted to each other, and then the L plate 2546 is moved to the storage groove 2545 At this time, the first group of liquid ports 2543 inside are opened, allowing the grinding liquid inside the liquid chamber 254 to be sprayed from the liquid ports 2543. At this time, the metal tube is also located at the first group of liquid ports 2543, until the magnet A2586 moves away from the first group of liquid ports 2543. At this time, the tension spring B2549 will reset the first group of L plates 2546. As the through groove 2585 continues to move, the same is true for the following two groups of liquid ports 2543. Finally, through the connection between the slide bar 2583 and the reciprocating screw 2541, the slide plate 258 can drive the ring 2581 to rotate and stir the grinding liquid inside the liquid chamber 254 when it moves, thereby preventing the particles inside the grinding liquid from sinking to the bottom and accumulating, thereby accurately spraying the grinding liquid onto the surface of the metal tube.

[0047] Specifically, when the metal tube moves from the tube groove 12 to the surface of the quartz roller A2363 and the quartz roller B243, the motor A226 is started to allow the threaded rod A227 to move diagonally downward with the connecting plate 231. When the connecting plate 231 starts to move, the gear 2362 will mesh with the teeth 224, thereby driving the quartz roller A2363 to rotate, and the rotation of the quartz roller A2363 will drive the metal tube and the quartz roller B243 to rotate together. When the extrusion plate 239 moves diagonally downward, it will contact one end of the C plate 255, thereby driving the C plate 255 to move to the right end, allowing the C plate 255 to move together with the connecting rod 257 and the slide plate 258. The push plate 2584 moves, and the magnet A2586 is attracted to the magnet B2547, so that the push plate 2584 also moves to the right with the L plate 2546. With the movement of the L plate 2546, the first liquid port 2543 is opened, and the sliding plate 258 in the moving state squeezes out the grinding liquid, allowing the grinding liquid to spray onto the surface of the metal tube. The rotating metal tube can increase the adhesion rate of the grinding liquid. With the continuous movement of the sliding plate 258, the magnet A2586 is separated from the surface of the L plate 2546. At this time, the tension spring B2549 brings the L plate 2546 back to the original position. The threaded sliding connection, when the slide plate 258 moves, the ring 2581 will rotate with the blade 2582 to stir the grinding liquid inside the liquid chamber 254 to prevent the grinding particles inside the grinding liquid from sinking to the bottom and accumulating. As the slide plate 258 continues to move, the metal tube will be sprayed with grinding liquid three times. When the transfer component 23 brings the metal tube to the center point of the bottom tank 221, the extrusion plate 239 will separate from one end of the C plate 255. At this time, the C plate 255 will be reset by the reset force of the tension spring A256. As the C plate 255 moves to the left, the C plate 255 will squeeze the gas inside the air cavity 252, allowing the liquid inside the air cavity 252 to spray out. The abrasive particles attached to the surface of the metal tube are dispersed, thereby improving the uniformity of the attachment of the abrasive particles. Since the discharge of the liquid is caused by the reset of the tension spring A256 and the squeezing of the C plate 255, the force of the gas ejected at this time is not very strong and will not blow away the abrasive particles. When the connecting plate 231 moves to the last group of air ports 2521, the motor B242 will flip over to let the metal tube roll into the polishing equipment 3. At this point, the grinding liquid is sprayed onto the surface of the metal tube through the squeezing of the slide plate 258, and then the gas is sprayed onto the surface of the metal tube through the C plate 255, so that the abrasive particles are evenly hung on the surface of the metal tube, thereby improving the polishing effect of the metal tube.
