[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0028] like Figures 1-5 As shown in the figure, the high-performance stainless steel bar mechanical polishing device includes a support and rotation unit 1 and a grinding and polishing unit 2 arranged in parallel. The support and rotation unit 1 is used to support and drive the stainless steel bar to rotate, and the grinding and polishing unit 2 is used to polish the bar and has blowing and dust suction functions.
[0029] The rotating support unit 1 is equipped with two rows of parallel support rollers 1a, one row being the driving roller and the other the driven roller, with the spacing between the two rows of support rollers 1a being variable. By adjusting the spacing between the two rows of support rollers 1a, it can adapt to the support requirements of stainless steel bars of different diameters. When the driving roller rotates, it drives the bar to rotate, and the driven roller rotates passively with the rotation of the bar, ensuring the stable rotation of the bar.
[0030] The polishing unit 2 includes a reciprocating slide 2a, on which a tilting frame 2b is mounted. The tilting frame 2b is connected to a polishing roller assembly 2c, a blowing air nozzle assembly 2d, and a dust suction nozzle assembly 2e. The tilting frame 2b changes the distance between the polishing roller assembly 2c and the supporting rotating unit 1. The reciprocating slide 2a can drive the tilting frame 2b and its connected components to move back and forth in a certain direction, thereby polishing different positions of the rod. The tilting frame 2b can adjust the distance between the polishing roller assembly 2c and the rod to adapt to different polishing requirements and rod diameters.
[0031] Specifically, a sliding sleeve is fixedly connected to the bottom of the reciprocating slide table 2a, and a reciprocating lead screw 2f is movably sleeved inside the sliding sleeve. One end of the reciprocating lead screw 2f is connected to the first drive motor 2g. The first drive motor 2g drives the reciprocating lead screw 2f to rotate. Under the cooperation of the sliding sleeve and the reciprocating lead screw 2f, the reciprocating slide table 2a is driven to reciprocate along the axial direction of the reciprocating lead screw 2f, thereby realizing the adjustment of the polishing position.
[0032] The tilting frame 2b includes a first cylinder, a lower rotating arm 2b-1 hinged to the upper rotating arm 2b-2. The lower rotating arm 2b-1 is hinged to the reciprocating slide table 2a via a first rotating shaft 2b-3. The lower rotating arm 2b-1 and the upper rotating arm 2b-2 are connected by a second rotating shaft 2b-4. The second rotating shaft 2b-4 is hinged to the top of the first cylinder, and the bottom of the first cylinder is hinged to the reciprocating slide table 2a via a third rotating shaft 2b-5. When the first cylinder extends or retracts, it pushes the lower rotating arm 2b-1 to rotate around the first rotating shaft 2b-3, thereby realizing the tilting action of the tilting frame 2b, and thus adjusting the distance between the polishing roller group 2c and the rod on the supporting rotating unit 1.
[0033] The polishing roller group 2c includes four parallel rotating rollers, one of which is a movable tension roller 2c-1, and the other three are fixed rollers 2c-2. The tension roller 2c-1 is connected to the upper rotating arm 2b-2 through a second cylinder 2c-3. The movable end of the second cylinder 2c-3 is connected to the tension roller 2c-1 through a bearing seat and presses the tension roller 2c-1 away from the upper rotating arm 2b-2. The fixed rollers 2c-2 are connected to the upper rotating arm 2b-2 through a bearing seat. One end of one of the fixed rollers 2c-2 is connected to a second drive motor 2c-4. A wide flexible polishing belt 2c-5 is sleeved around the four rotating rollers. The second drive motor 2c-4 drives the fixed roller 2c-2 to rotate. Under the tensioning action of the tensioning roller 2c-1, the wide flexible polishing belt 2c-5 moves with the rotation of the roller, achieving polishing of the bar. The second cylinder 2c-3 can adjust the position of the tensioning roller 2c-1, thereby adjusting the tension of the wide flexible polishing belt 2c-5 to ensure the polishing effect. Due to the friction between the outer surface of the wide flexible polishing belt 2c-5 and the surface to be polished, the surface of the stainless steel bar can be polished. The wide flexible polishing belt 2c-5 can fully contact the surface of the large-diameter bar, improving polishing efficiency and uniformity.
[0034] In this embodiment, two parallel rows of support rollers 1a are arranged at the same height. One row of support rollers 1a is driven through the middle by a drive shaft 1b, which is connected to a third drive motor 1c. The output shafts of the drive shaft 1b and the third drive motor 1c are each connected to a pulley, and the two pulleys are connected by a transmission belt. The third drive motor 1c drives the drive shaft 1b to rotate through the pulleys and the transmission belt, which in turn drives one row of support rollers 1a (driving rollers) to rotate. The friction between the driving rollers and the bar causes the bar to rotate.
[0035] A translation platform 1d is connected below the other row of support rollers 1a. A slide rail 1e is movably connected below the translation platform 1d, and the slide rail 1e is set perpendicular to the drive shaft 1b. The translation platform 1d can move along the slide rail 1e, thereby driving one row of support rollers 1a (driven rollers) to move, realizing the adjustment of the distance between the two rows of support rollers 1a to accommodate the support of bars of different diameters.
[0036] In a further optimized design, the blowing nozzle assembly 2d and the suction nozzle assembly 2e are arranged opposite each other, and are directly or via a bracket fixed to the upper rotating arm 2b-2. An open-type suction hood 2h is fitted around the suction nozzle assembly 2e. A polishing working area is formed on the outer side of the wide flexible polishing belt 2c-5 between the two fixed rollers 2c-2. This polishing working area is located between the opposing areas of the blowing nozzle assembly 2d and the suction nozzle assembly 2e, and is oriented towards the supporting rotating unit 1 with a variable distance between them. The blowing nozzle assembly 2d can blow away residual dust and metal particles from the polished bar surface; the suction nozzle assembly 2e, in conjunction with the suction hood 2h, can promptly remove dust and metal particles generated during the polishing process, reducing environmental pollution and protecting the health of operators.
[0037] The working process of this device is as follows: According to the diameter of the stainless steel bar to be polished, the passive wheel is moved along the slide rail 1e by the translation stage 1d to the row of support rollers 1a, and the distance between the two rows of support rollers 1a is adjusted to place the bar on the two rows of support rollers 1a. The third drive motor 1c is started, which drives the drive shaft 1b to rotate through the pulley and transmission belt, thereby driving the drive wheel to rotate, and the drive wheel drives the bar to rotate.
[0038] The first cylinder adjusts the tilting frame 2b, bringing the wide flexible polishing belt 2c-5 of the polishing roller assembly 2c into contact with the surface of the bar. The second cylinder 2c-3 adjusts the tensioning roller 2c-1 to achieve the appropriate tension for the wide flexible polishing belt 2c-5. The second drive motor 2c-4 is then activated, causing the fixed roller 2c-2 to rotate. The wide flexible polishing belt 2c-5 rotates with the rotating roller, polishing the bar.
[0039] Start the first drive motor 2g, which drives the reciprocating screw 2f to rotate, causing the reciprocating slide 2a to move back and forth along the reciprocating screw 2f, thereby driving the polishing roller group 2c to move along the axial direction of the bar, realizing polishing of the entire length of the bar. Compared with sanding disc, the wide flexible polishing belt 2c-5 can increase the polishing contact area and improve the polishing efficiency of the bar.
[0040] During the polishing process, the blowing nozzle assembly 2d blows the surface of the polished rod, while the dust suction nozzle assembly 2e, in conjunction with the dust suction hood 2h, sucks away the dust and metal particles generated during polishing.
[0041] The high-performance stainless steel bar mechanical polishing device of the present invention achieves stable support and rotation of large-diameter bars through the support and rotation unit 1, and the reciprocating slide 2a and the flipping frame 2b of the grinding and polishing unit 2 enable flexible adjustment of the polishing position and distance. The wide flexible polishing belt 2c-5 ensures polishing efficiency and quality, and the blowing and dust suction functions reduce environmental pollution. The overall device has a low degree of human intervention, good polishing quality, high efficiency and environmental protection, and is suitable for polishing large-diameter stainless steel bars.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. It should be noted that for those skilled in the art, any changes, modifications or additions made without departing from the concept of the present utility model should fall within the protection scope of the present utility model.
