Description

Technical Field

[0001] This utility model relates to the field of flat steel processing technology, specifically to a grinding and rust removal device for bright flat steel production. Background Technology

[0002] Bright flat steel is a rectangular flat steel product with a bright and smooth appearance, which has undergone special surface treatment. It is processed by cold rolling or cold drawing and then polished and wire-drawn to give the flat steel a bright and smooth surface.

[0003] According to Chinese Patent Publication No. CN216228669U, "A Grinding and Rust Removal Device for Bright Flat Steel Production," the main feature described is the use of a dust removal mechanism. This mechanism blows up debris and dust from the flat steel and collects it. The dust removal mechanism filters the dust-laden gas, cools it, and then blows the cooled gas onto the grinding and rust removal mechanism to further cool it. This achieves both dust reduction and temperature reduction of the grinding and rust removal mechanism, improving the device's effectiveness. Furthermore, by incorporating a pump, water can be sprayed onto the flat steel being processed, removing dust that was not collected by the dust removal mechanism and simultaneously cooling the grinding and rust removal mechanism, further enhancing the device's performance.

[0004] Flat steel can rust and produce oxides when exposed to rain or humid environments during production, which reduces the internal structural strength of the flat steel and makes it more prone to deformation or breakage under external forces. As can be seen in the aforementioned patent, a grinding roller is used to grind and remove rust from the flat steel. The grinding process requires grinding all four sides of the flat steel. After grinding one side of the flat steel, it needs to be turned over and put back into the grinding mechanism. The grinding process requires manual intervention and has low efficiency.

[0005] Therefore, a grinding and rust removal device for bright flat steel production is proposed to solve the problem of low grinding efficiency caused by the need for manual face changing of flat steel during grinding. Utility Model Content

[0006] The technical problem to be solved by this utility model is that the flat steel needs to be manually changed during grinding, resulting in low grinding efficiency. Therefore, a grinding and rust removal device for bright flat steel production is proposed.

[0007] The technical solution adopted by this utility model to solve the technical problem is as follows: a grinding and rust removal device for bright flat steel production, including a processing box and a feed inlet. Limiting grooves are provided on both sides of the processing box. A first motor is fixedly connected to the upper side of the limiting groove of the processing box. A first bidirectional lead screw is fixedly connected to the output end of the first motor. A first moving frame is threadedly connected to both sides of the first bidirectional lead screw, which are far apart from each other. A drive wheel is rotatably connected to one side of the first moving frame, and a rubber sleeve is fitted onto the drive wheel. Two connecting plates are fixedly connected inside the processing box. An electric push rod is fixedly connected to the two connecting plates. A second moving frame is fixedly connected to one end of the electric push rod. A grinding roller is rotatably connected inside the second moving frame. Two support plates are fixedly connected to the feed inlet of the processing box. A second motor is fixedly connected to the two support plates. A second bidirectional lead screw is fixedly connected to the output end of the second motor. Limiting frames are threadedly connected to both sides of the second bidirectional lead screw, which are far apart from each other. Limiting wheels are rotatably connected inside the limiting frames.

[0008] As a preferred technical solution of this utility model, a receiving frame is inserted into one side of the processing box, and a circular groove is opened on one side of the receiving frame. A bracket is fixedly connected in the circular groove, and a fan is rotatably connected to the bracket. By setting the fan, the abrasive debris in the processing box can be guided.

[0009] As a preferred technical solution of this utility model, a dustproof net is fixedly connected to the bracket. The dustproof net is located inside the receiving frame. By setting the dustproof net to block debris, the collection effect of grinding debris can be improved.

[0010] As a preferred technical solution of this utility model, the bottom four sides of the receiving frame are rotatably embedded with sliding balls, which are in contact with the bottom side of the processing box. The upper end of the receiving frame is open. By setting the sliding balls, the friction of the receiving frame movement can be reduced.

[0011] As a preferred technical solution of this utility model, a water pump is fixedly connected to the upper end of the processing box, a pipe is fixedly connected to the output end of the water pump, a square frame is fixedly connected to the bottom end of the pipe, and nozzles are uniformly fixedly connected inside the square frame. The water pump draws external polishing liquid and then sprays it out through the nozzles, which can improve polishing efficiency.

[0012] This utility model has the following advantages: by setting a relatively movable drive wheel in the processing box and cooperating with a limiting wheel on one side of the processing box, it can adapt to flat steel of different lengths and widths and facilitate the movement of the flat steel. Then, through the grinding rollers set horizontally and vertically, and driven by the electric push rod and the drive motor, it can provide a four-sided grinding effect and improve the grinding speed.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figure 1-3The device shown is a rust removal and abrasion treatment device for bright flat steel production, including a treatment box 1 and a feed inlet 2. Limiting grooves 3 are provided on both sides of the treatment box 1. A first motor, a second motor, and a third motor can be selected from the market based on actual needs. The motors execute their own programs. The first motor is fixedly connected to the treatment box 1 above the limiting grooves 3. The first motor drives a first bidirectional lead screw 4 to rotate, causing two first moving frames 5 to move relative to each other. The output end of the first motor is fixedly connected to the first bidirectional lead screw 4. The first moving frames 5 are threadedly connected to both sides of the first bidirectional lead screw 4, which are far apart from each other. A drive wheel 6 is rotatably connected to one side of each first moving frame 5, and a rubber sleeve is fitted onto the drive wheel 6. Two connecting plates 7 are fixedly connected inside the treatment box 1, and electric push rods 8 are fixedly connected to the two connecting plates 7. When the electric push rods 8 extend, they can cause two opposing second moving frames 9 to move relative to each other, and... The grinding roller 10 contacts the surface of the flat steel and provides abrasion and rust removal. One end of the electric push rod 8 is fixedly connected to the second moving frame 9. The sides of the first moving frame 5 and the second moving frame 9 are both fixedly connected to the third motor. The two third motors drive the drive wheel 6 and the grinding roller 10 in the first moving frame 5 and the second moving frame 9 to rotate, thereby moving and grinding the flat steel. The grinding roller 10 is rotatably connected in the second moving frame 9. The processing box 1 is fixedly connected to two support plates 11 at the feed inlet 2. The two support plates 11 are fixedly connected to the second motor. The second motor drives the second bidirectional lead screw 12 to rotate, which can cause the limiting wheel 14 to move relative to each other, thereby limiting it to the side of the flat steel. The output end of the second motor is fixedly connected to the second bidirectional lead screw 12. The two sides of the second bidirectional lead screw 12 that are far apart from each other are threadedly connected to the limiting frame 13. The limiting wheel 14 is rotatably connected in the limiting frame 13.

[0019] The processing box 1 has a receiving frame 15 inserted into one side, and a circular groove 16 is opened on one side of the receiving frame 15. A bracket is fixedly connected in the circular groove 16, and a fan 18 is rotatably connected on the bracket. By rotating the fan 18, the grinding debris can be guided, which facilitates the collection of the debris.

[0020] The bracket is fixedly connected to a dustproof net 17, which is located inside the receiving frame 15. By setting the dustproof net 17, debris can be prevented from overflowing.

[0021] Among them, the bottom four sides of the receiving frame 15 are rotatably embedded with sliding balls 19, which are in contact with the bottom side of the processing box 1. The upper end of the receiving frame 15 is open. By setting the sliding balls 19, the friction of the receiving frame 15 during movement can be reduced.

[0022] The upper end of the processing box 1 is fixedly connected to a water pump 20, the output end of the water pump 20 is fixedly connected to a pipe 21, the bottom end of the pipe 21 is fixedly connected to a square frame 22, and nozzles 23 are evenly fixedly connected inside the square frame 22. By setting the water pump 20 to be connected to the polishing fluid, and letting it enter the square frame 22 through the pipe 21, and then spraying it out through the nozzles 23, it can achieve the effects of cooling and lubrication, and can improve the polishing speed.

[0023] Working principle: Flat steel is fed into the processing box 1 through one of the feed ports 2. Then, the first motor drives the first bidirectional lead screw 4 to rotate, which causes the first moving frame 5 to move relative to the flat steel and the two drive wheels 6 to contact the upper and lower sides of the flat steel. Then, the second motor drives the second bidirectional lead screw 12 to rotate, which causes the second moving frame 9 to move relative to the flat steel. At this time, the limiting wheel 14 contacts the side of the flat steel. The electric push rod 8 on the left side of the processing box 1 extends, and the distance between the two grinding rollers 10 is consistent with the distance between the two drive wheels 6. At this time, the third motor on the first moving frame 5 drives the drive wheel 6 to rotate, so that one end of the flat steel moves into the processing box 1. At this time, the water pump 20 draws grinding fluid and sprays it through the square frame 22 and the nozzle 23 to contact the flat steel. Then, the four grinding rollers 10 start to grind the flat steel. At the same time, the fan 18 inside the receiving frame 15 rotates and provides guidance, which can facilitate the discharge of debris when the receiving frame 15 is pulled out.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
