Description

Technical Field

[0001] This invention belongs to the field of grinding equipment technology, specifically a batch grinding equipment for stainless steel bars. Background Technology

[0002] With the rapid development of modern industry, modern machinery has largely replaced manual operation. Machinery makes processing more efficient and also provides better safety for people. Grinding equipment is one such example. Compared with manual grinding, mechanical grinding takes less time. Stainless steel bars are workpieces with a certain length of round rod shape. In the production process of bars, stainless steel bars need to be cut. After cutting, their ends need to be ground. The current grinding method is generally to grind one bar at a time, which is time-consuming, labor-intensive, and has low grinding efficiency.

[0003] A patent application with publication number CN216151885U discloses a stainless steel bar grinding device. By setting a wastewater tank, a second support rod, a tray, a fixing plate, a water storage tank, a water outlet pipe, and a brush on the worktable, it can clean and cool the ground stainless steel bars, making them easier to handle and use later. By setting a stainless steel bar connecting groove, a threaded hole, an external threaded rod, an internal threaded rod, a grinding block, a limiting rod, and a rotating plate, it is easy to adjust the front and rear distance of the grinding block, so that the stainless steel bars can be easily contacted and ground with stainless steel bars of different sizes.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1: As Figure 1 - Figure 7 As shown in the figure, a batch polishing device for stainless steel bars according to an embodiment of the present invention includes a workbench 1. Polishing components are respectively arranged on both sides of the upper end of the workbench 1. The polishing components include polishing wheels 11 rotatably arranged on both sides of the upper end of the workbench 1. A transport component is arranged on one side of the polishing wheel 11. The transport component includes a belt 12 rotatably arranged on one side of the polishing wheel 11. The belt 12 is used to press down on several stainless steel bars and transport them. A first baffle 13 is arranged on the side of the polishing wheel 11 away from the belt 12. The first baffle 13 is used to abut against the ends of several stainless steel bars to make the ends of several stainless steel bars flush.

[0023] Specifically, when grinding stainless steel bars, they are usually ground one by one. This requires placing each bar into the grinding machine sequentially, making it impossible to grind multiple bars simultaneously in batches, resulting in low grinding efficiency. In this grinding device, several stainless steel bars are neatly arranged on the upper part of the worktable 1. The grinding wheel 11 is then driven downwards, simultaneously moving the belt 12 and the first baffle 13 downwards. The first baffle 13 is positioned on both sides of the ends of the stainless steel bars, limiting their movement. The belt 12 presses against the upper ends of the bars, and the grinding wheel 11 is positioned on both sides of the bars. The stainless steel rods are polished by rotating the polishing wheel 11. Then, the driving belt 12 rotates, causing several stainless steel rods at the lower end to rotate. While the stainless steel rods are rotating, the polishing wheel 11 polishes the ends of the stainless steel rods around their perimeter until the ends of the stainless steel rods are polished. During the polishing process, the first baffle 13 limits the stainless steel rods to keep their ends neat. The driving belt 12 can drive several stainless steel rods to rotate simultaneously, and the polishing wheel 11 can polish the ends of multiple stainless steel rods at the same time, greatly improving polishing efficiency.

[0024] like Figure 3 As shown, an L-shaped strip 111 is provided on one side of the grinding wheel 11, and the grinding wheel 11 is installed in the middle of the L-shaped strip 111. An mounting plate 121 is provided on the upper end of the belt 12, and the belt 12 is installed in the middle of the mounting plate 121. A first L-shaped plate 14 is fixedly connected to the upper end of the L-shaped strip 111. The mounting plate 121 is fixedly connected to one side of the first L-shaped plate 14 through a first L-shaped block 122. A second L-shaped block 131 is fixedly connected to one side of the first baffle 13, and the second L-shaped block 131 is provided on one side of the first L-shaped plate 14 through a first rectangular strip 132.

[0025] like Figure 4 - Figure 5 As shown, a base plate 4 is fixedly connected to the lower end of the workbench 1, and a second L-shaped plate 15 is fixedly connected to the upper end of the first L-shaped plate 14. A rectangular tube 153 is provided on the upper end of the second L-shaped plate 15, and the second L-shaped plate 15 is slidably disposed inside the rectangular tube 153.

[0026] like Figure 5 As shown, an electric slide table 154 is fixedly connected to the upper end of the rectangular tube 153, and an electric slide rail 1541 is provided on the upper end of the electric slide table 154. The lower sides of both ends of the electric slide rail 1541 are fixedly connected to the upper end of the base plate 4 through rectangular plates 155.

[0027] like Figure 5As shown, the second L-shaped plate 15 has a first rectangular hole 151 in the middle of its upper end, and the rectangular tube 153 has a rectangular groove 1531 in the middle. The second rectangular strip 152 slides through the middle of the first rectangular hole 151 and is located inside the rectangular groove 1531.

[0028] like Figure 5 As shown, the upper middle part of the rectangular plate 155 is provided with a second rectangular hole 1551, and the two ends of the second rectangular strip 152 are respectively slidably disposed inside the second rectangular hole 1551. The lower sides of the two ends of the second rectangular strip 152 are fixedly connected to the output end of the electric telescopic rod 1552, and the electric telescopic rod 1552 is fixedly connected to one side of the rectangular plate 155.

[0029] like Figure 4 As shown, the first rectangular strip 132 is slidably disposed on one side of the first L-shaped plate 14. Cylindrical rods 1322 are fixedly connected to both sides of the upper end of the first rectangular strip 132. The cylindrical rods 1322 slide through the upper end of the first L-shaped plate 14. A lead screw 1321 is threadedly connected to the middle of the first rectangular strip 132. The upper end of the lead screw 1321 is rotatably disposed in the middle of the first L-shaped plate 14.

[0030] Specifically, when grinding several stainless steel bars, after placing the bars on the upper part of the workbench 1, the electric telescopic rod 1552 is driven to extend and retract. The electric telescopic rod 1552 drives the second rectangular bar 152 to move downward. The second rectangular bar 152 drives the second L-shaped plate 15 to slide inside the rectangular tube 153. The second rectangular bar 152, through the second L-shaped plate 15, drives the first L-shaped plate 14 to move downward. The first L-shaped plate 14, through the second L-shaped block 131, drives the first baffle 13 to move downward, so that the first L-shaped plate 14 moves downward. A baffle 13 is tightly attached to the upper end of the workbench 1. The first L-shaped plate 14 drives the grinding wheel 11 and belt 12 to move downward through the first L-shaped block 122 and L-shaped strip 111, so that the grinding wheel 11 and belt 12 are located on the upper end of several stainless steel bars. When it is necessary to grind stainless steel bars of different diameters, the lead screw 1321 is rotated. The rotation of the lead screw 1321 simultaneously drives the first rectangular strip 132 to slide on one side of the first L-shaped plate 14. The first rectangular strip 132 drives the cylindrical rod 1322 on the first L-shaped plate 14. The upper middle section slides, and the first rectangular bar 132 drives the first baffle 13 to move through the second L-shaped block 131. The distance between the first baffle 13 and the grinding wheel 11 and the belt 12 can be adjusted, which can be used to grind stainless steel bars of different diameters. After adjusting the distance between the grinding wheel 11 and the belt 12, the electric slide tables 154 on both sides are then driven to slide on the electric slide rail 1541. The electric slide tables 154 drive the second L-shaped plate 15 to slide outside the second rectangular bar 152 through the rectangular cylinder 153. When the second L-shaped plate 15 moves, it drives the grinding wheel 11 and the belt 12 at the lower end to move, and at the same time, it can drive the first baffle 13 to move. The second L-shaped plates 15 on both sides move at the same time, and at the same time drive the first baffle 13 at the lower end to move, so that the first baffle 13 on both sides moves to a certain position. At both ends of the stainless steel bars, the first baffle 13 limits the movement of several stainless steel bars to keep their ends neat. Then, the grinding wheel 11 is driven to rotate, which can grind the ends of several stainless steel bars at the same time. At the same time, the belt 12 is driven to rotate, which can drive several stainless steel bars to rotate at the same time. When several stainless steel bars rotate at the same time, the grinding wheel 11 can grind all four sides of several stainless steel bars, which greatly improves the grinding efficiency. At the same time, the distance between the second L-shaped plates 15 on both sides can be adjusted, as can the distance between the first baffles 13 on both sides, the distance between the grinding wheels 11 on both sides, and the distance between the belts 12, which can be adjusted to accommodate stainless steel bars of different lengths. By adjusting the distance between the first baffle 13, the grinding wheel 11, and the belt 12, it can be adapted to stainless steel bars of different diameters.

[0031] Example 2: Figure 6 As shown in the first embodiment, another embodiment of the present invention is as follows: a first inclined plate 2 is provided on one side of the workbench 1, the first inclined plate 2 is located at the lower end of the workbench 1, and a collection box 21 is provided at the lower end of the first inclined plate 2.

[0032] Specifically, the stainless steel rod at the top of the workbench 1 is rotated and polished by the drive belt 12. After polishing, the stainless steel rod continues to rotate until it reaches the side of the first inclined plate 2. Then it slides along the first inclined plate 2 into the collection box 21 for unified collection.

[0033] like Figure 6 As shown, a second baffle 22 is slidably disposed on both sides of the upper end of the first inclined plate 2, and the second baffle 22 is connected to the first baffle 13 through the first connecting frame 23.

[0034] Specifically, when the polished stainless steel rod slides downwards from the upper end of the first inclined plate 2, the second baffle 22 is fixed to the side of the first baffle 13 near the first inclined plate 2 via the first connecting frame 23, so that the second baffle 22 always moves with the position of the first baffle 13. When the polished stainless steel rod slides downwards along the first inclined plate 2, the second baffle 22 can limit the stainless steel rod sliding at the upper end of the first inclined plate 2. A collection box 21 of the same size as the polished stainless steel rod can be placed at the lower end of the first inclined plate 2, so that the stainless steel rod can fall neatly into the collection box 21, reducing the subsequent steps of sorting the stainless steel rod.

[0035] like Figure 7 As shown, a second inclined plate 3 is provided on the side of the workbench 1 away from the first inclined plate 2. The second inclined plate 3 is located at the upper end of the workbench 1. A third baffle 31 is slidably provided on both sides of the upper end of the second inclined plate 3. The third baffle 31 is connected to the first baffle 13 through a second connecting frame 32.

[0036] Specifically, when feeding stainless steel bars, several stainless steel bars are placed on the upper end of the second inclined plate 3. Since the first baffle 13 is fixed to the side of the second inclined plate 3 by the second connecting frame 32, the third baffle 31 can move with the first baffle 13. When several stainless steel bars to be polished slide down the upper end of the second inclined plate 3, the third baffle 31 limits the sliding stainless steel bars, so that the stainless steel bars can roll neatly to the upper end of the worktable 1.

[0037] Working principle: When grinding several stainless steel bars at the same time, feeding is required first. Several stainless steel bars are placed on the upper end of the second inclined plate 3. Since the first baffle 13 is fixed to the side of the second inclined plate 3 by the second connecting frame 32, the third baffle 31 can move with the first baffle 13. When several stainless steel bars to be ground slide down the upper end of the second inclined plate 3, the third baffle 31 limits the sliding stainless steel bars, so that the stainless steel bars can roll neatly to the upper end of the worktable 1. Subsequently, the electric telescopic rod 1552 is driven to extend and retract. The electric telescopic rod 1552 drives the second rectangular bar 152 to move downward. The second rectangular bar 152 drives the second L-shaped plate 15 to slide inside the rectangular tube 153. The second rectangular bar 152 drives the first L-shaped plate 14 to move downward through the second L-shaped plate 15. The first L-shaped plate 14 drives the first baffle 13 to move downward through the second L-shaped block 131, so that the first baffle 13 is tightly attached to the upper end of the worktable 1. The first L-shaped plate 14 drives the grinding wheel 11 and belt 12 to move downward through the first L-shaped block 122 and L-shaped bar 111, so that the grinding wheel 11 and belt 12 are located on the upper end of several stainless steel bars. When it is necessary to grind stainless steel bars of different diameters, the lead screw 1321 is driven to rotate. The rotation of the lead screw 1321 simultaneously drives the first rectangular bar 132 to slide on one side of the first L-shaped plate 14. The first rectangular bar 132 drives the cylindrical rod 1322 on the first L-shaped plate 14. The upper middle section slides, and the first rectangular bar 132 drives the first baffle 13 to move through the second L-shaped block 131. The distance between the first baffle 13 and the grinding wheel 11 and the belt 12 can be adjusted, which can be used to grind stainless steel bars of different diameters. After adjusting the distance between the grinding wheel 11 and the belt 12, the electric slide tables 154 on both sides are then driven to slide on the electric slide rail 1541. The electric slide tables 154 drive the second L-shaped plate 15 to slide outside the second rectangular bar 152 through the rectangular cylinder 153. When the second L-shaped plate 15 moves, it drives the grinding wheel 11 and the belt 12 at the lower end to move, and at the same time, it can drive the first baffle 13 to move. The second L-shaped plates 15 on both sides move at the same time, and at the same time drive the first baffle 13 at the lower end to move, so that the first baffle 13 on both sides moves to a certain position. At both ends of the stainless steel bar, the first baffle 13 limits the ends of several stainless steel bars to keep them neat. Then, the grinding wheel 11 is driven to rotate, which can grind the ends of several stainless steel bars at the same time. At the same time, the belt 12 is driven to rotate, which can drive several stainless steel bars to rotate at the same time. When several stainless steel bars rotate at the same time, the grinding wheel 11 can grind all four sides of several stainless steel bars, which greatly improves the grinding efficiency. At the same time, the distance between the second L-shaped plates 15 on both sides can be adjusted, which can also adjust the distance between the first baffles 13 on both sides, as well as the distance between the grinding wheels 11 on both sides and the belt 12. This can be applied to stainless steel bars of different lengths. By adjusting the distance between the first baffle 13, the grinding wheel 11 and the belt 12, it can be applied to stainless steel bars of different diameters. When the polished stainless steel rod slides downwards from the upper end of the first inclined plate 2, the second baffle 22 is fixed to the side of the first baffle 13 near the first inclined plate 2 via the first connecting frame 23, so that the second baffle 22 always moves with the position of the first baffle 13. When the polished stainless steel rod slides downwards along the first inclined plate 2, the second baffle 22 can limit the stainless steel rod sliding at the upper end of the first inclined plate 2. A collection box 21 of the same size as the polished stainless steel rod can be placed at the lower end of the first inclined plate 2, so that the stainless steel rod can fall neatly into the collection box 21, reducing the subsequent steps of sorting the stainless steel rod.
