Description

Technical Field

[0001] This invention belongs to the field of idler roller processing technology, specifically relating to a machine tool for turning idler rollers in a rolling mill mechanism. Background Technology

[0002] A roll lathe is a lathe specifically designed for machining rolls, which are typically large, thick, and heavy cylindrical rolls used on rolling mills. Therefore, during machining, a support roller device is needed to support the rolls. However, existing support roller devices can cause the rolls to vibrate during rotation when supporting rolls with uneven surfaces or those with hard, adhering particles, affecting the lathe's machining accuracy. Furthermore, during machining, it's impossible to directly observe and detect uneven areas on the supported roll surface, hindering subsequent turning of the outer diameter. Additionally, the support roller device lacks protective devices on the outside during rotation, and the rotating roll lacks restraints, making it prone to rolling off the support roller device and causing safety accidents.

[0003] To address the aforementioned problems, this application proposes a machine tool for turning idler rollers in a rolling mill mechanism. Summary of the Invention

[0004] To address the problems mentioned in the background section, this invention provides a machine tool turning device for roller mechanisms. This device allows hard protrusions to be effectively avoided by an elastically designed avoidance arc plate, reducing roller sway during rotation. It also facilitates the adjustment of the exposed length of the marking cotton as the size of the protruding particles on the outer side of the roller changes, allowing operators to visually observe uneven areas and facilitating subsequent processing. Furthermore, it allows for the limitation of rotating rollers, preventing them from rolling off and causing safety accidents. During roller rotation, a scraper removes hard particles adhering to the outer side of the roller, while a cleaning brush cleans impurities adhering to the surface of the support roller and the avoidance arc plate, ensuring stable roller rotation and improving processing quality.

[0014] As a preferred embodiment of the machine tool turning idler roller device for the rolling mechanism of the present invention, the surface of the L-shaped push plate is slidably connected with a guide rod, the guide rod is installed in a strip groove opened on the surface of the support base plate, and a spring is sleeved on the outer surface of the guide rod.

[0017] As a preferred embodiment of the machine tool turning roller device for a rolling mechanism of the present invention, a cleaning brush is installed on the bottom surface of the U-shaped support column, the length of the cleaning brush is greater than the length of the support roller, and a collection box is provided on the surface of the load-bearing plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use.

[0019] 1. By incorporating an obstacle avoidance marking assembly, and through the coordinated use of supporting rollers, avoidance arc plates, L-shaped slide bars, abutment arc plates, wedge-shaped push blocks, and marking cotton, the roller, under its own weight, rolls between the two supporting rollers during use, achieving a self-centering effect. Simultaneously, during rotation, the roller's own weight ensures that the compressed avoidance arc plate is on the same horizontal plane as the supporting rollers. If the outer surface of the roller contains hard protrusions that contact the avoidance arc plate, the arc plate is compressed, and its height will be lower than that of the supporting rollers. This allows the hard protrusions to be effectively avoided by the elastically designed avoidance arc plate, reducing roller sway during rotation. This design improves processing accuracy and allows the abutting arc plate at one end of the L-shaped slide bar to contact the wedge-shaped push block, pushing the wedge-shaped push block to slide to one side on the surface of the L-shaped fixed plate. This compresses the return spring, and the wedge-shaped push block drives the sliding sleeve connected by the connecting plate to slide to one side, opening the fixed shell. The marking cotton inside the fixed shell can be pushed out from the fixed shell under the elasticity of the leaf spring, marking the surface of the roller. As the size of the raised particles changes, the distance the wedge-shaped push block slides increases as the L-shaped slide bar drives the abutting arc plate, and the longer the marking cotton is exposed, resulting in larger marks on the surface of the roller. This allows processing personnel to visually observe uneven areas, facilitating subsequent processing.

[0020] 2. By incorporating an anti-derailment component, and through the coordinated use of wedge blocks, toothed plates, half-gears, and L-shaped stop bars, the load-bearing plate moves downwards under the weight of the rollers during use. Guided by the telescopic rod and spring three, the load-bearing plate moves smoothly downwards, allowing the wedge blocks at the bottom of the load-bearing plate to push the L-shaped push plate outwards. Guided by the guide rod, the L-shaped push plate slides smoothly outwards, causing the toothed plates on the outside of the L-shaped push plate to drive the half-gear to rotate. The rotation of the half-gear causes the L-shaped stop bar to rotate around the shaft pin, deflecting the L-shaped stop bar to the outside of the rollers to limit their movement and prevent the rolling rollers from rolling off and causing a safety accident.

[0021] 3. By incorporating a cleaning component, the U-shaped support, scraper, tension spring, and cleaning brush work together to ensure that the inclined scraper, under the action of the tension spring, always elastically abuts against the outside of the roll during rotation. Simultaneously, as the roll rotates, the scraper removes hard particles adhering to the outside of the roll, and its inclined design guides the scraped impurities into a collection box for centralized collection. Furthermore, removing some impurities from the outside of the roll further ensures the stability of the roll during the rotation process over the support roller. The cleaning brush also cleans impurities adhering to the support roller and the surface of the avoidance arc plate, ensuring the smooth rotation of the roll and improving processing quality.

The cleaning component 4 includes a U-shaped support 41, a scraper 42, a tension spring 43, a cleaning brush 44, and a collection box 45. The U-shaped support 41 and the tension spring 43 are fixedly installed on one side of the U-shaped support 41, and the scraper 42 is used to clean hard particles on the surface of the roll.

[0051] The surface of the U-shaped support column 41 is inclined and slidably connected to a scraper 42. One end of the tension spring 43 is connected to the scraper 42. The side of the scraper 42 that abuts against the roller is tapered.

[0052] A cleaning brush 44 is installed on the bottom surface of the U-shaped support column 41. The length of the cleaning brush 44 is greater than the length of the support roller 23, and a collection box 45 is provided on the surface of the support plate 21.

[0053] The working principle and usage process of this invention are as follows: In use, the roll is first lifted using a hoisting auxiliary tool and placed between two symmetrically arranged support rolls 23. The roll rolls under its own weight and rolls between the two support rolls 23, achieving a self-centering effect. Simultaneously, during the rotational processing, the roll's own weight ensures that the compressed relief arc plate 24 is on the same horizontal plane as the support rolls 23. If the outer surface of the roll contains hard protrusions that contact the relief arc plate 24, the relief arc plate 24 is compressed, and its height will be lower than the support rolls 23. This allows the hard protrusions to be effectively avoided by the elastically arranged relief arc plate 24, reducing the roll's sway during rotation and improving processing accuracy. At this time, the L-shaped sliding rod 26 installed on one side of the relief arc plate 24 can slide within the fixed sleeve 25 following the relief arc plate 24. The spring 27 can be compressed, causing the abutting arc plate 28 at one end of the L-shaped slide bar 26 to contact the wedge-shaped push block 201, and pushing the wedge-shaped push block 201 to slide to one side on the surface of the L-shaped fixed plate 29, causing the return spring 203 to be compressed. The wedge-shaped push block 201 will drive the sliding sleeve 206 connected by the connecting plate 204 to slide to one side to open the fixed shell 205. The marking cotton 207 (which can be filled with liquid pigment) inside the fixed shell 205 can be pushed out from the fixed shell 205 under the elasticity of the leaf spring 208 to mark the surface of the roller. As the size of the raised particles increases, the distance that the wedge-shaped push block 201 slides is greater as the L-shaped slide bar 26 drives the abutting arc plate 28, and the longer the length of the marking cotton 207 exposed is, the larger the mark on the surface of the roller is, making it easier for the processing personnel to visually observe the uneven parts and facilitate subsequent processing.

[0054] Meanwhile, when the roll is placed between the two sets of support rolls 23, the load-bearing plate 21 will move downward under the weight of the roll. Under the limiting guidance of the telescopic rod 39 and the spring 301, the load-bearing plate 21 moves smoothly downward, so that the wedge block 32 installed at the bottom of the load-bearing plate 21 can push the L-shaped push plate 33 to slide outward. Under the guidance of the guide rod 35, the L-shaped push plate 33 can slide out smoothly, so that the toothed plate 34 installed on the outside of the L-shaped push plate 33 drives the half gear 37 to rotate. The rotation of the half gear 37 drives the L-shaped stop rod 38 to rotate around the shaft pin, so that the L-shaped stop rod 38 deflects to the outside of the roll to limit the roll and prevent the rolling roll from rolling down and causing a safety accident.

[0055] When the roll rotates for processing, the inclined scraper 42, under the action of the tension spring 43, can always elastically abut against the outside of the roll. At the same time, when the roll rotates, the scraper 42 can scrape off the hard particles adhering to the outside of the roll, and through its own inclined setting, guide the scraped impurities into the collection box 45 for centralized collection. After scraping off some impurities on the outside of the roll, it can further ensure the stability of the roll during the rotation process of the support roll 23. The cleaning brush 44 can also clean the impurities adhering to the surface of the support roll 23 and the avoidance arc plate 24, ensuring the stability of the roll during rotation and improving the processing quality.

[0056] It should be noted that there is a rotating shaft pin inside the half gear 37, which is fixed to the surface of the support base plate 31. This shaft pin is used to limit the rotation of the half gear 37.

[0057] It should be noted that the telescopic rod 39 is composed of two rods with different diameters, with the smaller diameter rod slidingly connected inside the larger diameter rod.

[0058] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. 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.
