Description

Technical Field

[0001] This utility model belongs to the field of angle steel production technology, specifically an angle steel pre-straightening device for an angle steel production line. Background Technology

[0002] Angle steel, commonly known as angle iron in the industry, is a long strip of steel with two sides perpendicular to each other, forming an angle. It is usually made of ordinary carbon structural steel and low alloy steel. Angle steel production lines are automated equipment used to produce angle steel, and are used for processing such as punching or shearing.

[0003] Angle steel raw materials may deform or bend due to pressure generated during stacking or transportation. In such cases, pre-straightening is required before processing to straighten the raw materials for subsequent processing. During long-term use and observation, it was found that angle steel straightening machines are used to straighten angle steel by pressing it with extrusion rollers. However, metal shavings, rust, and other impurities on the angle steel can adhere to the surface of the extrusion rollers, causing scratches on the angle steel and affecting the quality of the finished angle steel product.

[0004] Therefore, this utility model provides an angle steel pre-straightening device for an angle steel production line. Utility Model Content

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 3As shown in the embodiment of this utility model, an angle steel pre-straightening device for an angle steel production line includes a side plate 1; a motor 11 is fixedly connected to the side wall of the side plate 1; multiple drive rollers 12 are rotatably connected to the inner side wall of the side plate 1; the drive rollers 12 and the motor 11 are driven by a chain; multiple fixed shafts 13 are fixedly connected to the inner side wall of the side plate 1; a driven roller 14 is rotatably connected to the middle of the fixed shaft 13; the driven roller 14 is correspondingly arranged with the drive roller 12; a connecting assembly is provided in the middle of the fixed shaft 13; an adjusting assembly is installed on the connecting assembly; a scraper 15 is installed in the adjusting assembly; a fixed plate 16 is fixedly connected to the inner side wall of the side plate 1; multiple wire brushes 17 are fixedly connected to the side wall of the fixed plate 16; during operation, the motor 11 is started to drive the multiple drive rollers 12 to rotate through the chain, and then the angle steel is transferred from the drive rollers 12 to the side wall. The angle steel passes between the drive roller 12 and the fixed shaft 13. At this time, the angle steel is conveyed to the production line under the friction and extrusion of the drive roller 12 and the fixed shaft 13. At the same time, the drive roller 12 and the fixed shaft 13 can straighten the angle steel under the extrusion. When the drive roller 12 rotates, the wire brush 17 will continuously brush its surface. When the fixed shaft 13 rotates with the movement of the angle steel, the scraper 15 will scrape the surface of the fixed shaft 13, thereby scraping off the metal debris and rust and other impurities adhering to the surface of the drive roller 12 and the fixed shaft 13. Through the above structure, the fixed plate 16, the wire brush 17 and the scraper 15 are set to facilitate the cleaning of the surface of the drive roller 12 and the fixed shaft 13, thereby reducing the adhesion of debris and rust and other impurities on the surface of the angle steel, which would cause the surface of the angle steel to be scratched during the conveying process and affect the quality of the finished angle steel.

[0025] like Figure 1 and Figure 2 As shown, the adjusting assembly includes a fixed frame 2; the fixed frame 2 is fixedly connected to the end of the connecting assembly; two sets of spring telescopic rods 21 are fixedly connected to the side wall of the fixed frame 2; a baffle 22 is fixedly connected to the end of each set of spring telescopic rods 21; a scraper 15 is slidably installed inside the fixed frame 2; during operation, the scraper 15 is inserted into the fixed frame 2, and then the end of the scraper 15 contacts the surface of the fixed shaft 13. At this time, the spring telescopic rods 21 will be in a stretched state. In the continuous friction between the scraper 15 and the fixed shaft 13, the scraper 15 will generate wear. When wear and tear causes the scraper to shorten, the spring telescopic rod 21 will retract and rebound, causing the baffle 22 to press the scraper 15 against the surface of the fixed shaft 13, thus making the scraper 15 fit tightly against the fixed shaft 13. With the above structure, by setting the fixed frame 2, the spring telescopic rod 21 and the baffle 22, the spring telescopic rod 21 can drive the baffle 22 to press the scraper 15 against the surface of the fixed shaft 13, thereby reducing the situation where the scraper 15 becomes shorter due to wear and tear during long-term use and does not contact the fixed shaft 13, thus losing the scraping effect on the surface of the fixed shaft 13.

[0026] like Figure 3As shown, a hopper 3 is fixedly connected to the inner wall of the side plate 1; the hopper 3 has an inclined structure; a discharge port 31 is opened on the side wall of the side plate 1; a collection trough 32 is fixedly connected to the side wall of the side plate 1; during operation, when impurities on the surface of the angle steel and impurities scraped off from the surfaces of the drive roller 12 and the fixed shaft 13 fall downwards, the hopper 3 will catch the falling impurities and guide them to the discharge port 31. When the impurities slide out from the discharge port 31, they will enter the collection trough 32 for collection. Through the above structure, the hopper 3, the discharge port 31 and the collection trough 32 are set to facilitate the catching and collection of falling impurities, thereby reducing the pollution of the workshop environment caused by the scattering of impurities, and the situation where impurities fall below the side plate 1 and are inconvenient to clean and collect.

[0027] like Figure 4 As shown, a cylinder 4 is fixedly connected to the side wall of the side plate 1; a push plate 41 is fixedly connected to the end of the cylinder 4; during operation, starting the cylinder 4 to extend can drive the push plate 41 to move along the direction of the hopper 3. At this time, the push plate 41 can push out the impurities remaining in the hopper 3 from the outlet 31 and then collect them in the collection tank 32. Then, the cylinder 4 is retracted to drive the push plate 41 to reset. Through the above structure, the cylinder 4 and the push plate 41 are set to facilitate the discharge of some impurities remaining in the hopper 3, so as to reduce the accumulation and blockage caused by impurities remaining in the hopper 3.

[0028] like Figure 4 As shown, the side wall of the collection tank 32 is provided with a sliding groove 5; a drawer box 51 is placed inside the collection tank 32; during operation, the drawer box 51 is inserted into the collection tank 32 through the sliding groove 5. When impurities slide out from the discharge port 31, they will enter the drawer box 51 and be collected. When it is necessary to clean the collected impurities, the drawer box 51 can be pulled out and the impurities inside can be poured out. Then the drawer box 51 can be inserted back into the collection tank 32 to reset. Through the above structure, the drawer box 51 and the collection tank 32 are set to slide together, which facilitates the cleaning of collected impurities and improves the convenience of use.

[0029] like Figure 2 As shown, the connecting assembly includes a pair of fixing frames 6; the pair of fixing frames 6 are symmetrical; the fixing frames 6 are fixedly connected to the middle of the fixing shaft 13; a fixing block 61 is fixedly connected to the side wall of the fixing frame 2; the fixing frames 6 and the fixing blocks 61 are connected by bolts; during operation, the fixing blocks 61 are aligned with the openings of the fixing frames 6, and then the fixing blocks 61 are inserted into the fixing frames 6, and then the fixing frames 6 and the fixing blocks 61 are fixed by bolts. At this time, the positions of the fixing frame 2 and the scraper 15 can be fixed, and during the pressing of the fixing blocks 61, the scraper 15 contacts the surface of the fixing shaft 13, and will squeeze the baffle 22 to stretch the spring telescopic rod 21. Through the above structure, the fixing frames 6 and the fixing blocks 61 are set to facilitate the disassembly of the fixing frame 2 and the scraper 15, so as to improve the convenience of maintenance or replacement of the fixing frame 2 and the scraper 15.

[0030] like Figure 4 As shown, the push plate 41 is made of rubber. By setting the push plate 41 to be made of flexible rubber through the above structure, the wear caused by friction between the push plate 41 and the hopper 3 can be reduced, and its service life can be improved.

[0031] Working principle: The starting motor 11 drives multiple drive rollers 12 to rotate via a chain. Angle steel passes between the drive rollers 12 and the fixed shaft 13. During this process, the angle steel is conveyed onto the production line under the friction and pressure of the drive rollers 12 and the fixed shaft 13. Simultaneously, the pressure from the drive rollers 12 and the fixed shaft 13 straightens the angle steel. As the drive rollers 12 rotate, the wire brush 17 continuously brushes their surface. When the fixed shaft 13 rotates with the angle steel, the scraper 15 scrapes its surface, thus removing any adhering material from the drive rollers 12 and the fixed shaft 13. Metal shavings and rust on the surface of the fixed shaft 13 are scraped off. The scraper 15 is then inserted into the fixed frame 2, and the end of the scraper 15 contacts the surface of the fixed shaft 13. At this time, the spring telescopic rod 21 will be in a stretched state. With the continuous friction between the scraper 15 and the fixed shaft 13, the scraper 15 will wear down and shorten in length. At this time, the spring telescopic rod 21 will retract and rebound, driving the baffle 22 to press the scraper 15 against the surface of the fixed shaft 13, so that the scraper 15 is in close contact with the fixed shaft 13. When impurities on the surface of the angle steel and from the drive roller 12 and the fixed shaft 13 are removed, the scraper 15 is removed. After the impurities scraped off the surface fall down, the hopper 3 catches them and guides them towards the outlet 31. Once the impurities slide out of the outlet 31, they enter the collection trough 32 for collection. Activating the cylinder 4 extends the push plate 41, moving it along the direction of the hopper 3. The push plate 41 then pushes out the remaining impurities from the outlet 31, allowing them to enter the collection trough 32. Then, the cylinder 4 retracts, resetting the push plate 41 and inserting the drawer 51 from the slide 5 into the collection trough 32. When impurities slide out of the outlet 31, they enter the collection trough 32. The impurities are collected in the drawer 51. When it is necessary to clean the collected impurities, the drawer 51 can be pulled out and the impurities inside can be poured out. Then the drawer 51 can be inserted back into the collection slot 32 to reset. The fixing block 61 can be aligned with the opening of the fixing frame 6. Then the fixing block 61 can be inserted into the fixing frame 6. Then the fixing frame 6 and the fixing block 61 can be fixed with bolts. At this time, the position of the fixing frame 2 and the scraper 15 can be fixed. During the pressing of the fixing block 61, the scraper 15 contacts the surface of the fixing shaft 13 and will squeeze the baffle 22 to stretch the spring telescopic rod 21.
