Description

Technical Field

[0001] This utility model relates to the field of straightening machine technology, specifically to a self-cleaning device for a straightening machine. Background Technology

[0002] A straightening machine is a device used to straighten metal profiles, bars, tubes, wires, etc. Its working principle is primarily based on the plastic deformation characteristics of metal materials. When the metal material being straightened passes through the rollers of the straightening machine, it undergoes repeated bending deformation. This bending deformation changes the stress distribution within the metal, gradually causing the metal material to become straighter. Specifically, parameters such as the arrangement of the straightening rollers and the amount of pressure applied are adjusted according to the original degree of bending of the metal material and the required straightening accuracy to ensure that the straightened metal material achieves the expected straightness.

[0003] During the use of a straightening machine, metal materials such as bars may have particulate impurities or contaminants such as rust adhering to them. When these contaminated bars are straightened by the concave or convex rollers of the straightening machine, the particulate impurities and rust are transferred to the rollers. The adhesion of these contaminants not only affects the surface finish of the straightening rollers but may also alter the dimensional and shape accuracy of the rollers, thereby further affecting the stability of the straightening process and the straightening accuracy of the final product. Utility Model Content

A support platform one is installed above the concave roller, and a support platform two is installed above the convex roller. A cleaning mechanism one is fixedly connected to the support platform one, and a cleaning mechanism two is fixedly connected to the support platform two. An electric telescopic rod is fixedly connected to both the support platform one and the support platform two. A fixed seat is fixedly connected to the lower end of the electric telescopic rod. A cleaning mechanism is detachably connected to the fixed seat, and a fixing component is threadedly connected to the fixed seat.

[0006] Furthermore, the cleaning mechanism includes a vortex air pump fixedly connected to a support platform. The output end of the vortex air pump is fixedly connected to an air distribution cylinder.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 4 A self-cleaning device for a straightening machine includes a straightening machine body 1, on which a concave roller 2 and a convex roller 3 are mounted. A support platform 4 is mounted above the concave roller 2, and a support platform 5 is mounted above the convex roller 3. A first cleaning mechanism is fixedly connected to the first support platform 4, and a second cleaning mechanism is fixedly connected to the second support platform 5. An electric telescopic rod 6 is fixedly connected to both the first support platform 4 and the second support platform 5. A fixed seat is fixedly connected to the lower end of the electric telescopic rod 6. A cleaning mechanism is detachably connected to the fixed seat, and a fixing component is threadedly connected to the fixed seat.

[0021] like Figures 1 to 4 As shown, in the self-cleaning device of the straightening machine of this utility model, the concave roller 2 and convex roller 3 are rotating during use to straighten bent metal rods. At this time, cleaning mechanisms one and two are activated, using the high-pressure gas generated by cleaning mechanisms one and two to rinse the concave roller 2 and convex roller 3. When encountering impurities that cannot be blown off, the electric telescopic rod 6 is activated. The output end of the electric telescopic rod 6 moves downward, causing the fixed seat and cleaning mechanism to move downward, scraping off the impurities that cannot be blown off the surface of the concave roller 2 and convex roller 3, ensuring that the surface of the concave roller 2 and convex roller 3 of the straightening machine remains clean at all times. This improves the dimensional and shape accuracy of the rollers.

[0022] like Figure 1 As shown, the cleaning mechanism includes a vortex air pump 7 fixedly connected to a support platform 4. The output end of the vortex air pump 7 is fixedly connected to an air distribution cylinder 8. Two air guide pipes 9 are installed at the lower end of the air distribution cylinder 8. A nozzle 10 is fixedly connected to the lower end of each of the two air guide pipes 9.

[0023] Specifically, during the straightening process of metal rods, the vortex air pump 7 delivers high-pressure gas to the inside of the air distribution cylinder 8, and then flows into the two air guide pipes 9. The high-pressure gas is sprayed from the two nozzles 10 onto the surface of the concave roller 2, thereby washing away the rust or impurity particles adhering to the surface of the concave roller 2.

[0024] like Figure 4 As shown, the second cleaning mechanism includes a vortex air pump 11 fixedly connected to the second support platform 5. The output end of the vortex air pump 11 is fixedly connected to an air distribution cylinder 12. An air guide pipe 13 is installed at the lower end of the air distribution cylinder 12. A nozzle 14 is fixedly connected to the lower end of each air guide pipe 13.

[0025] Specifically, the vortex air pump 211 delivers high-pressure gas to the interior of the air distribution cylinder 212, and then flows into the air guide pipe 213. The high-pressure gas is sprayed from the nozzle 214 onto the surface of the cam roller 3, thereby washing away the rust or impurity particles adhering to the surface of the cam roller 3.

[0026] like Figure 4 As shown, the fixing base includes a fixing block 15 fixedly connected to the electric telescopic rod 6. The fixing block 15 has a slot 16 and a threaded hole 17 communicating with the slot 16 on its outer wall.

[0027] Specifically, the slot 16 on the fixing block 15 is used to initially fix the cleaning mechanism, while the threaded hole 17 is used to fix the fixing component.

[0028] like Figure 4 As shown, the cleaning mechanism includes a card block 18 that is adapted to the card slot 16. A scraper 19 is fixedly connected to the lower end of the card block 18. An insertion hole 20 with the same center as the threaded hole 17 is provided on the card block 18.

[0029] Specifically, the clamping block 18 is placed inside the clamping slot 16, with the width of the clamping block 18 being the same as the width of the clamping slot 16. The fixing component is then threaded into the threaded hole 17 to secure the cleaning mechanism. When the surface of the concave roller 2 or convex roller 3 contains rust or impurities that cannot be blown off, the electric telescopic rod 6 is activated, causing the scraper 19 to move downwards and gradually contact the surface of the concave roller 2 or convex roller 3. During the straightening of the metal rod, the concave roller 2 and convex roller 3 rotate, allowing the scraper 19 to clean away the impurities that cannot be blown off, ensuring that the surfaces of the concave roller 2 and convex roller 3 of the straightening machine remain smooth. This improves the dimensional and shape accuracy of the rollers.

[0030] like Figure 4 As shown, the scraper 19 is a high molecular weight polyethylene plate or a polyurethane plate.

[0031] Specifically, high-molecular-weight polyethylene or polyurethane sheets have good corrosion resistance and a certain degree of wear resistance, causing less damage to the roller surface and helping to protect it.

[0032] like Figure 4 As shown, the fixing assembly includes a tightening bolt 21 threaded onto a threaded hole 17, and a plug rod 22 adapted to the insertion hole 20 is fixedly connected to the front end of the tightening bolt 21.

[0033] Specifically, after connecting the cleaning mechanism to the fixed base, the tightening bolt 21 is threaded into the threaded hole 17. The insertion rod 22 at the front end of the tightening bolt 21 will also be inserted into the insertion hole 20, thereby firmly fixing the cleaning mechanism to the fixed base. The cleaning mechanism can be removed and replaced by following the reverse operation.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
