[0002] As is known, stainless steel pipe is a hollow long round steel, which is widely used in industrial pipelines and mechanical structural parts such as petroleum, chemical, medical, food, light industry, mechanical instruments, etc. In addition, when the bending and torsional strengths are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used as furniture and kitchen utensils. In the production and manufacturing of stainless steel pipes, polishing is a very important process in the surface treatment of stainless steel pipes, which is related to the quality of subsequent finished products.

[0003] For example, the patent application with announcement number CN217617617U and publication date October 21, 2022, and named "A casting forming device for the production of stainless steel pipe fittings", the utility model provides a casting forming device for the production of stainless steel pipe fittings, including a base: a mounting seat is provided at the top of the base, and a mold base is fixedly installed at the top of the mounting seat. By arranging an electromagnet, a guide rod, a first spring and an inner ring, during the forming process of the stainless steel pipe fitting, the fan on the upper shelf can be started, and the heat dissipation of the mold base can be accelerated by the fan, thereby improving the forming efficiency of the stainless steel pipe fitting. After the stainless steel pipe fitting is formed inside the mold base, the upper shelf is pushed upward by the hydraulic cylinder to open the top of the mold base, and then the electromagnet at the top of the guide rod is started. The inner ring is attracted by the magnetic force of the electromagnet, which will drive the inner ring to slide upward along the guide rod. The inner ring will be inserted from the bottom of the mold base, and the formed stainless steel pipe fitting will be pushed out of the mold base, so that the stainless steel pipe fitting can be taken out by a clamp, and then the raw materials can be continued to be introduced for production, which greatly increases the production efficiency of stainless steel pipe fittings.

[0004] In the prior art, when common stainless steel pipes are polished, workers generally use sandpaper or polishing equipment to polish the stainless steel pipes. When workers use sandpaper to polish, their arms need to swing back and forth, which requires more manpower, and the workers' hands are prone to soreness during long-term polishing.

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] like Figures 1 to 6 As shown, a stainless steel pipe polishing device provided by an embodiment of the utility model includes: a base plate 1, a plurality of polishing units are evenly arranged on the base plate 1 along its linear direction, the polishing units include support rods 2 and grinding stones 3, a plurality of support rods 2 are evenly arranged on the base plate 1 along its linear direction, a grinding stone 3 is obliquely arranged on the top end of each support rod 2, a supporting inclined plate 4 is arranged on the base plate 1, and the supporting inclined plate 4 and each of the grinding stones 3 are perpendicularly arranged to each other.

[0028] Specifically, the bottom plate 1 is a flat plate for installing the supporting inclined plate 4 and the supporting rod 2. The grinding stone 3 is a grinding stone for polishing the outer wall of the stainless steel pipe, which is used for polishing the stainless steel pipe. The stainless steel pipe is a square stainless steel pipe body, which is convenient for the grinding stone 3 to polish the outer wall of the stainless steel pipe. A plurality of supporting rods 5 are evenly arranged at the bottom end of the supporting inclined plate 4. The supporting rods 5 are evenly arranged along the inclination direction of the supporting inclined plate 4. The bottom end of each supporting rod 5 is connected to the bottom plate 1, so that the bottom plate 1 and the supporting rod 5 support the supporting inclined plate 4. Each supporting inclined plate 4 is close to the grinding stone 3. One side is inclined downward from the end away from the grinding stone 3 to the end close to the grinding stone 3, and the end of the supporting inclined plate 4 away from the grinding stone 3 is a flat plate. When the stainless steel pipe needs to be polished, the staff transports the stainless steel pipe to the supporting inclined plate 4 through the conveying equipment. When the stainless steel pipe slides from the flat plate on the supporting inclined plate 4 to its inclined surface, the stainless steel pipe slides from the inclined surface on the supporting inclined plate 4 to the end close to the grinding stone 3 until the stainless steel pipe slides to the lowest end of the inclined surface of the supporting inclined plate 4. Since the supporting inclined plate 4 and each of the grinding stones 3 are arranged perpendicular to each other, the stainless steel pipe is pressed against the grinding stone on the supporting inclined plate 4 at this time. On the outer wall of the sandstone 3, the staff uses a propulsion device to push the stainless steel pipes pressed against the grinding stone 3 to move synchronously, so that the grinding stone 3 can grind and polish the stainless steel pipes pressed against it synchronously, and can grind and polish multiple stainless steel pipes synchronously, thereby improving the efficiency of the grinding and polishing of the stainless steel pipes. In the prior art, when common stainless steel pipes are polished, the staff generally uses sandpaper or grinding equipment to polish the stainless steel pipes. When the staff uses sandpaper for polishing, the arm needs to swing back and forth, which requires more manpower, and the staff will waste a lot of manpower when polishing for a long time. The hands of the workers are prone to soreness; when the workers hold the grinding equipment for a long time to polish the stainless steel pipe, the polishing effect is poor due to the unstable holding of the grinding equipment by the workers; in this embodiment, when the stainless steel pipe needs to be polished, the workers place the stainless steel pipe on the supporting inclined plate 4, so that the outer wall of the stainless steel pipe on the supporting inclined plate 4 is pressed against the grinding stone 3, and the stainless steel pipe on the supporting inclined plate 4 is pushed to slide along the supporting inclined plate 4, so that the grinding stone 3 polishes the outer wall of the stainless steel pipe, realizes the automatic polishing of the stainless steel pipe by the grinding stone 3, and thus reduces the labor intensity of the workers.

[0029] Furthermore, an auxiliary inclined plate 6 is provided at the top of each support rod 2, and a slide groove 7 is provided on each auxiliary inclined plate 6. A sliding plate 8 is slidably installed in each slide groove 7, and a connecting rod 9 is installed on each sliding plate 8, and a grinding stone 3 is installed on each connecting rod 9; a lead screw 10 is rotatably installed in each slide groove 7, and each lead screw 10 passes through the corresponding sliding plate 8 and is threadedly connected to it; one end of each lead screw 10 away from the grinding stone 3 passes through the auxiliary inclined plate 6 and is connected to a first driving member 11.

[0030] Specifically, when the stainless steel tube slides from the inclined surface on the supporting inclined plate 4 to the lowest end, the stainless steel tube on the supporting inclined plate 4 is not pressed against the outer wall of the grinding stone 3 (that is, the gap between the grinding stone 3 and the outer wall of the stainless steel tube is large) or the grinding stone 3 blocks the stainless steel tube from sliding toward the lowest end of the supporting inclined plate 4 (that is, the gap between the grinding stone 3 and the supporting inclined plate 4 is small, thereby blocking the stainless steel tube from sliding toward the lowest end of the supporting inclined plate 4), the first driving member 11 is started (the first driving member 11 is a device for forward and reverse rotation of the driving end, preferably a motor, or a manual A rotating crank or other rotating element) drives the lead screw 10 to rotate, and the lead screw 10 drives the sliding plate 8 to slide in the slide groove 7 through threaded cooperation, the sliding plate 8 drives the connecting rod 9 to move, and the connecting rod 9 drives the grinding stone 3 to move until the grinding stone 3 and the outer wall of the stainless steel pipe are pressed against each other, so that the grinding stone 3 can grind and polish the outer wall of the stainless steel pipe. By changing the position of the sliding plate 8 in the slide groove 7, the distance between the grinding stone 3 and the outer wall of the stainless steel pipe and the pressing force can be adjusted, thereby improving the grinding and polishing effect of the grinding stone 3 on the stainless steel pipe.

[0031] In another embodiment provided by the utility model, each of the sliding plates 8 is respectively installed with a limit unit, and the limit unit includes a limit circular plate 12, each of the sliding plates 8 is rotatably installed with a positioning round rod 13, and each end of the positioning round rod 13 is connected to a connecting rod 9, each of the positioning round rods 13 is respectively installed with a limit circular plate 12, and each of the limit circular plates 12 is evenly provided with a plurality of limit holes 14 along its circumferential direction; each of the sliding plates 8 is respectively installed with a positioning plate 15, and each of the positioning plates 15 is respectively slidably installed with a limit circular rod 16, and each of the limit circular rods 16 and its corresponding limit hole 14 are mutually plugged and matched, and each of the limit circular rods 16 is respectively installed with a return plate 17 at one end away from the limit circular plate 12, and each of the sliding plates 8 is installed with a reset plate 18, and each of the return plates 17 and its corresponding reset plate 18 are connected by an elastic member 19.

[0032] Specifically, when it is necessary to adjust the angle between the grinding stone 3 and the stainless steel pipe, the staff pushes the return plate 17 to move it toward one end of the reset plate 18, so that the return plate 17 squeezes the elastic member 19 (the elastic member 19 is a component capable of telescopic reset, preferably a spring), so that the elastic member 19 is in a compressed state, and the return plate 17 drives the limiting round rod 16 to slide out of the limiting hole 14 on the limiting circular plate 12, so that the limiting round rod 16 releases the limiting operation on the limiting circular plate 12, and the staff rotates the connecting rod 9 and the grinding stone 3 until the grinding stone 3 and the stainless steel pipe are aligned. After the angle between the outer walls of the stainless steel pipe reaches the optimal grinding and polishing position, the staff releases the pushing force applied to the return plate 17. Under the rebound effect of the elastic member 19, the elastic member 19 pushes the return plate 17 to slide toward one end of the limiting circular plate 12. The return plate 17 drives the limiting round rod 16 to be inserted into the limiting hole 14 on the limiting circular plate 12, so that the limiting round rod 16 performs a rotation limiting operation on the limiting circular plate 12, so that the grinding stone 3 does not rotate when grinding the outer wall of the stainless steel pipe, providing a stable working environment for the grinding stone 3 to grind and polish the stainless steel pipe.

[0033] In another embodiment of the utility model, a portion of the bottom plate 1 between two adjacent polishing units is provided with a conveying unit, and the conveying unit includes a support rod 2, an auxiliary inclined plate 6, a slide groove 7, a sliding plate 8, a lead screw 10 and a first driving member 11. The support rod 2, the auxiliary inclined plate 6, the slide groove 7, the sliding plate 8, the lead screw 10 and the first driving member 11 are installed in the same manner as on the polishing unit. Each sliding plate 8 on the conveying unit is provided with a straight rod 20, and each end of each straight rod 20 is installed with A U-shaped frame 21, a driving shaft 22 is rotatably installed between the inner walls of each U-shaped frame 21, a polishing roller 23 is installed on the part of each driving shaft 22 located between the U-shaped frames 21, and one end of each driving shaft 22 away from the bottom plate 1 passes through the U-shaped frame 21 and is installed with a synchronous wheel 24; each of the synchronous wheels 24 is connected by a synchronous belt 25, a second driving member 26 is installed on one of the U-shaped frames 21, and the output end of the second driving member 26 is connected to the synchronous wheel 24 on the corresponding U-shaped frame 21.

[0034] Specifically, when the grinding stone 3 and the outer wall of the stainless steel tube are not in tight contact with each other, the first driving member 11 drives the lead screw 10 to rotate, and the lead screw 10 drives the sliding plate 8 to slide in the sliding groove 7 through threaded cooperation, and the sliding plate 8 drives the straight rod 20 to move, and the straight rod 20 drives the grinding stone 3 to move until the grinding stone 3 and the outer wall of the stainless steel tube are in tight contact with each other; when the grinding stone 3 and the outer wall of the stainless steel tube are in tight contact with each other, the second driving member 26 is started (the first driving member 11 is a device for forward and reverse rotation at the driving end, preferably a motor) to drive the synchronous wheel 24 to rotate. Since the synchronous wheels 24 are mutually transmitted through the synchronous belt 25, all the synchronous wheels 24 can rotate synchronously in the same direction, so that the synchronous wheel 24 drives the driving shaft 22 to rotate, and the driving shaft 22 drives the polishing roller 23 to rotate, so that the polishing roller 23 transports the stainless steel tube, and at the same time, the polishing roller 23 polishes the outer wall of the stainless steel tube, thereby improving the transportation efficiency and polishing effect of the stainless steel tube.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
