Description

Technical Field

[0001] This utility model relates to the field of steel strip production technology, specifically to a burr removal device for steel strip production. Background Technology

[0002] Steel strip is a strip material made from carbon steel. As an important basic material in industry, its diverse classifications and properties make it suitable for special fields such as shipbuilding, bridges and packaging. Steel strip can be divided into hot-rolled steel strip and cold-rolled steel strip according to the processing method. In the production and processing of cold-rolled steel strip, burrs will appear on the edge of the steel strip due to cutting and other operations. In order to avoid affecting the quality and appearance of the steel strip, workers will use grinding machines and other devices to remove the burrs on the edge of the steel strip.

[0003] In existing deburring devices for steel strip production, the grinding discs used for deburring gradually wear down during long-term operation. To ensure that the deburring efficiency and effect are not affected, workers replace the severely worn grinding discs. However, since most of the grinding discs are located inside the machine housing, workers need to disassemble the machine housing before they can remove the grinding discs. This replacement method is cumbersome and affects the efficiency of steel strip deburring to some extent, which is not conducive to the continuous deburring of steel strips. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-9 As shown, a burr removal device for steel strip production includes a base plate 1. A processing box 2 is fixedly connected to the center of the top surface of the base plate 1. Inspection ports 11 are provided on both sides of the inner wall of the processing box 2. Each inspection port 11 has an inspection plate 12 inside. A U-shaped frame 17 is fixedly connected to the side of the two inspection plates 12 that are close to each other. Two drive shafts 18 are symmetrically arranged at both ends of the U-shaped frame 17. A grinding component 19 for removing burrs from the edges of the steel strip is provided at the end of each drive shaft 18 that is close to each other. By setting the grinding component 19, the burrs on both sides of the steel strip can be removed. A drive component 20 for providing rotational force to the drive shafts 18 is provided on the side of the inspection plate 12 away from the U-shaped frame 17. Component 20 can drive the drive shaft 18 and the grinding component 19 to perform the removal of burrs from the steel strip. It should be noted that the drive shaft 18 can be mounted on the U-shaped frame 17 via rotating parts such as bearings. Two support seats 14 are symmetrically installed at both ends of the inspection plate 12. A rotating shaft 15 is vertically installed on the side of the two support seats 14 that is far apart from each other. Limiting plates 13 are vertically installed at the top and bottom of the inspection port 11. One end of the rotating shaft 15 is rotatably connected to the limiting plate 13. The bottom of the lower limiting plate 13 is provided with a transmission component 16 for rotating the inspection plate 12. By setting the transmission component 16, when the grinding component 19 is severely worn and needs to be replaced, the entire inspection plate 12 can be rotated to the outside of the processing box 2, which facilitates the disassembly and maintenance of the grinding component 19.

[0030] Both sides of the processing box 2 have openings 3, and strip plates 4 are fixedly connected to the bottom of both sides of the openings 3. Multiple support rollers 5 are symmetrically arranged between adjacent strip plates 4, and the support rollers 5 are rotatably connected to the strip plates 4 at both ends. At least two supports 7 are provided at the bottom of the strip plates 4, and the supports 7 are respectively connected to the strip plates 4 and the base plate 1. Figure 1 , Figure 2 As shown, the openings 3 on both sides of the processing box 2 facilitate the entry and exit of the steel strip to be ground, and the support rollers 5 arranged at equal intervals between the strip plates 4 can support the steel strip from the bottom, which is conducive to the removal of burrs from the steel strip.

[0031] A strip-shaped seat 8 is fixedly connected to the top of the opening 3. Multiple L-shaped rods 9 are symmetrically installed on one side of the strip-shaped seat 8. Each L-shaped rod 9 has a limit roller 10 rotatably connected to its bottom end. Figure 1 As shown, the limiting roller 10 at the bottom of the L-shaped rod 9 can position the steel strip that enters the processing box 2, thus keeping the steel strip in a horizontal state, which is beneficial to improving the burr removal effect of the steel strip.

[0032] The grinding assembly 19 includes a grinding disc 191 disposed at one end of a drive shaft 18. A mating protrusion 192 is vertically mounted on the side of the grinding disc 191 closest to the drive shaft 18. A mating groove 193 corresponding to the mating protrusion 192 is formed inside the drive shaft 18. The mating protrusion 192 is located inside the mating groove 193. Countersunk holes 194 are formed on both sides of the mating groove 193. Fastening bolts 196 are installed inside the countersunk holes 194. Internal threaded grooves 195 corresponding to the fastening bolts 196 are formed on both sides of the mating protrusion 192. One end of the fastening bolt 196 passes through the countersunk hole 194 and is spirally connected to the internal threaded groove 195. Figure 5 , Figure 6 and Figure 9 As shown, when replacing the grinding disc 191, the fastening bolt 196 located inside the countersunk hole 194 can be unscrewed using an Allen wrench. At this time, the grinding disc 191 is no longer restricted, and the mating protrusion 192 can be pulled out from inside the mating groove 193. Then, the worker can install the new grinding disc 191 on the drive shaft 18 according to the above steps.

[0033] The drive assembly 20 includes a dual-axis motor 201 fixed to one side of the inspection plate 12. A drive sprocket 203 is fixedly connected to the output end of the dual-axis motor 201. One end of the drive shaft 18 extends through the outside of the U-shaped frame 17 and is fixedly connected to a driven sprocket 202. The drive sprocket 203 and the driven sprocket 202 are connected by a drive chain. Figure 4 , Figure 8 As shown, the dual-axis motor 201 can drive the drive sprockets 203 on the outer side of its two output ends to rotate synchronously. Then, the drive sprockets 203 drive the grinding assembly 19 located at the bottom of the transmission shaft 18 to rotate through the driven sprocket 202, thus performing the burr removal work on the steel strip.

[0034] A protective cover 21 is provided on the outside of the driven sprocket 202. The protective cover 21 is connected to the U-shaped frame 17 by bolts. Figure 5 , Figure 6 As shown, by setting the protective cover 21, some of the removed burrs can be prevented from entering between the driven sprocket 202 and the transmission chain. This avoids the burrs affecting the fit between the driven sprocket 202 and the transmission chain, which helps to improve the working stability of the drive assembly 20.

[0035] The transmission assembly 16 includes a fixed base 162 fixed to the bottom of the limiting plate 13. A worm gear 163 is rotatably connected inside the fixed base 162. A rotating block 164 is fixedly connected to one end of the worm gear 163. A rotating shaft 15 located below extends through to the outside of the limiting plate 13 and is fixedly connected to a worm wheel 161. One side of the worm wheel 161 meshes with the worm gear 163. Figure 6 , Figure 7 As shown, when the grinding assembly 19 is severely worn and needs replacement, the rotating block 164 and worm gear 163 can drive the worm wheel 161 to rotate. The worm wheel 161 then drives the inspection plate 12 to flip over to the outside of the processing box 2 via the rotating shaft 15. This simplifies the replacement process of the grinding assembly 19, reduces the difficulty of replacing the grinding assembly 19, and facilitates the disassembly and maintenance of the grinding assembly 19. It should also be noted that, as Figure 4 As shown, in order to ensure the smooth flipping of the inspection plate 12, a certain flipping gap should be left between the two sides of the inspection plate 12 and the inspection port 11.

[0036] Waste guide plates 22 are fixedly connected to both sides of the inner wall of the processing box 2. A pull-out box 6 is slidably connected to the bottom of the inner cavity of the processing box 2. The pull-out box 6 is located below the waste guide plates 22, and one side of the pull-out box 6 extends to the outside of the processing box 2. Figure 2 , Figure 3 As shown, the burrs removed from the edge of the steel strip will fall into the interior of the pull-out box 6 along the inclined surface of the waste guide plate 22. After the pull-out box 6 is full of burrs, it can be pulled out from the processing box 2 and moved to a designated location for dumping.

[0037] Working principle: First, the operator can introduce the steel strip to be processed into the processing box 2 through the through-hole 3. Then, the driving component 20 and the grinding component 19 can grind the two edges of the steel strip respectively, thus removing the burrs on both edges of the steel strip. Then, the waste guide plate 22 and the pull-out box 6 can collect and collect the burrs generated during the grinding process. When the grinding component 19 is severely worn and needs to be replaced, the transmission component 16 can drive the inspection plate 12 to flip to the outside of the processing box 2. This simplifies the replacement process of the grinding component 19, reduces the difficulty of replacing the grinding component 19, and facilitates the disassembly, assembly and maintenance of the grinding component 19.
