Description

Technical Field

[0001] This utility model relates to the field of cold rolling mill technology, specifically to a cold rolling mill lower support roll mounting device. Background Technology

[0002] In the modern steel and non-ferrous metal processing industry, cold rolling mills play a crucial role. From early simple rolling equipment to today's highly automated, high-precision, and complex mechanical systems, cold rolling mills have undergone a long process of technological innovation. They can further process hot-rolled metal sheets, significantly improving the surface quality, dimensional accuracy, and mechanical properties of the sheets through cold rolling. Widely used in industries such as automobile manufacturing, home appliance production, and building decoration, they play a key supporting role in promoting the development of these industries.

[0003] According to a public disclosure of a cold rolling mill lower support roll installation device (publication number: CN221869734U), it includes: a base plate, a fixing plate one fixedly connected to the top of the outer surface of the base plate, a round rod fixedly connected to the outer surface of the fixing plate one near its top, a fixing semicircular plate fixedly connected to the end of the round rod away from the fixing plate one, a fixing plate two fixedly connected to the top of the outer surface of the base plate near the fixing plate one, and a threaded rod movably embedded in the interior of the fixing plate two near its top, one end of the threaded rod being rotatably connected to a movable semicircular plate via a bearing.

[0004] The aforementioned application involves cumbersome, time-consuming, and labor-intensive installation of the support rolls, which needs improvement. Therefore, we propose a support roll installation device for a cold rolling mill. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a cold rolling mill lower support roll installation device, which solves the technical problem of cumbersome operation, time and labor cost in the process of installing support rolls.

[0006] According to one aspect, at least one embodiment of the present invention provides a cold rolling mill lower support roller mounting device, comprising: a mounting plate, a support roller disposed on the top of the mounting plate, an installation facilitation mechanism disposed on the top of the mounting plate, the installation facilitation mechanism comprising a hollow plate, the hollow plate being fixedly connected to the top of the mounting plate, a rotating shaft passing through the side of the hollow plate, a threaded rod being fixedly connected to the end of the output shaft of the rotating shaft, a threaded block being threadedly connected to the circumferential surface of the threaded rod, a fixing block being fixedly connected to the top of the threaded block, a fixing disc being fixedly connected to the side of the fixing block, a hollow tube being fixedly connected to the inner wall of the fixing disc, a return spring being fixedly connected to the bottom of the inner wall of the hollow tube, a fixing rod being fixedly connected to the end of the return spring away from the hollow tube, and a limit rod being fixedly connected to the inner wall of the hollow plate.

[0007] For example, in at least one embodiment of the present invention, a cold rolling mill lower support roll installation device is provided, which further includes: a contact head fixedly connected to the end of the fixed rod away from the return spring, and a handle fixedly connected to the circumferential surface of the rotating shaft. The design of the handle facilitates the rotation of the threaded rod by the operator.

[0008] The fixing rod is slidably connected to the inner wall of the hollow tube, and the initial state of the return spring is set to a relaxed state. The design of the return spring is conducive to effective clamping according to the diameter of the support roller.

[0009] The threaded block is slidably connected to the circumferential surface of the limiting rod. The installation mechanism is set in two sets, and the design of the limiting rod facilitates the linear movement of the two threaded blocks.

[0010] The support roller contacts the contact head, and the side cross-section of the contact head is set to be elliptical. The design of the contact head is conducive to the fixed rod sliding inside the hollow tube when squeezed by the support roller.

[0011] According to another aspect, at least one embodiment of the present invention also provides a cold rolling mill lower support roll installation device, comprising: an adjustable support mechanism, the adjustable support mechanism including a groove, the groove being formed on the side of a fixed block, a telescopic rod being fixedly connected to the top of the threaded block, a support plate being fixedly connected to the end of the telescopic rod away from the threaded block, and a contact plate being fixedly connected to the top of the support plate. The purpose of this design is to facilitate effective support of the support roll and prevent swaying.

[0012] For example, in at least one embodiment of the present invention, a cold rolling mill lower support roll installation device is provided, which further includes: a connecting spring fixedly connected to the inner side wall of the groove, and a limit block fixedly connected to the end of the connecting spring away from the groove. The design of the limit block is beneficial to effectively support the support plate.

[0013] The side section of the support plate is L-shaped, and the contact plate is in contact with the support roller. The design of the contact plate helps to prevent the support roller from moving downward due to gravity.

[0014] The side section of the limiting block is set to an arc shape, and the limiting block is in contact with the support plate. The design of the limiting block and the support plate facilitates easy operation by the staff.

[0015] The number of the limiting blocks is set to two sets, and they are arranged linearly on the inner sidewall of the groove. The support plate is located inside the groove. The above design is beneficial for better support of the support roller.

[0016] The beneficial effects of the embodiments of this utility model are as follows:

[0017] In this invention, the rotational force of the rotating shaft drives the threaded rod, threaded block, fixed block, fixed disc, hollow tube, return spring, fixed rod, contact head and other components to work together, thereby rotating the handle fixed on the circumference of the rotating shaft, which in turn drives the rotating shaft to rotate. The rotation of the rotating shaft drives the threaded rod fixed on the circumference of the end away from the handle to rotate. When the threaded rod rotates, it drives the two threaded blocks threaded to the circumference to slide closer to each other on the circumference of the limiting rod. The operation process is simple and convenient during the installation of the support roller, and it is highly practical.

[0018] In this invention, the downward movement of the support plate drives the components such as the groove, telescopic rod, contact plate, connecting spring, and limiting block to work together to press or pull the support plate, thereby causing the support plate to press against the limiting block fixed at the other end of the connecting spring. At this time, the support plate presses against the arc surface of the limiting block, and at the same time, the connecting spring fixed to the inner wall of the groove is compressed and contracts. After the support roller is installed, it supports the support roller to prevent movement. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0027] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0028] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-5 As shown, this invention illustrates a cold rolling mill lower support roller mounting device according to an embodiment of the present invention, comprising: a mounting plate 1, a support roller 2 disposed on the top of the mounting plate 1, an installation facilitating mechanism 3 disposed on the top of the mounting plate 1, the installation facilitating mechanism 3 comprising a hollow plate 31, the hollow plate 31 being fixedly connected to the top of the mounting plate 1, a rotating shaft 312 passing through the side of the hollow plate 31, a threaded rod 33 being fixedly connected to the end of the output shaft of the rotating shaft 312, a threaded block 34 being threadedly connected to the circumferential surface of the threaded rod 33, a fixing block 35 being fixedly connected to the top of the threaded block 34, a fixing disk 36 being fixedly connected to the side of the fixing block 35, a hollow tube 37 being fixedly connected to the inner wall of the fixing disk 36, a return spring 38 being fixedly connected to the bottom of the inner wall of the hollow tube 37, a fixing rod 39 being fixedly connected to the end of the return spring 38 away from the hollow tube 37, and a limit rod 311 being fixedly connected to the inner wall of the hollow plate 31.

[0033] In some examples, a contact head 310 is fixedly connected to the end of the fixed rod 39 away from the return spring 38, and a handle 32 is fixedly connected to the circumferential surface of the rotating shaft 312. The design of the handle 32 facilitates the rotation of the threaded rod 33 by the operator.

[0034] The fixing rod 39 is slidably connected to the inner wall of the hollow tube 37. The initial state of the return spring 38 is set to the relaxed state. The design of the return spring 38 is conducive to effective clamping according to the diameter of the support roller 2.

[0035] The threaded block 34 is slidably connected to the circumferential surface of the limiting rod 311, which facilitates the installation of two sets of the mechanism 3. The design of the limiting rod 311 is conducive to the linear movement of the two threaded blocks 34.

[0036] The support roller 2 contacts the contact head 310. The side cross section of the contact head 310 is set to be elliptical. The design of the contact head 310 is conducive to the fixed rod 39 sliding inside the hollow tube 37 when it is squeezed by the support roller 2.

[0037] For example, such as Figures 1-5As shown, when the support roller 2 needs to be installed, the worker places the support roller 2 on the top of the support plate 43, which is fixed to the top of the support plate 43. Then, the handle 32 fixed to the circumferential surface of the rotating shaft 312 is rotated, thereby driving the rotating shaft 312 to rotate. The rotation of the rotating shaft 312 drives the threaded rod 33 fixed to the circumferential surface away from the handle 32 to rotate. When the threaded rod 33 rotates, it drives the two threaded blocks 34 threaded to the circumferential surface to slide closer to each other on the circumferential surface of the limiting rod 311. At the same time, it drives the fixing blocks 35 fixed to the top of the threaded blocks 34 to move closer to each other. The movement of the fixing blocks 35 drives the fixing blocks 35 fixed to the side to move closer to each other. The movement of disc 36 simultaneously drives the movement of hollow tube 37 fixed to the inner wall. When hollow tube 37 moves, it drives the movement of fixed rod 39 sliding on the inner wall. The movement of fixed rod 39 drives the movement of contact head 310 fixed at the other end. At this time, support roller 2 squeezes multiple contact heads 310. When multiple contact heads 310 are squeezed, fixed rod 39 slides downward on the inner wall of hollow tube 37, thereby squeezing the return spring 38 fixed at the bottom of the inner wall into a taut state. As threaded rod 33 continues to rotate, contact head 310 contacts the circumferential surface of support roller 2, clamping support roller 2 to complete the installation step.

[0038] like Figures 1-5 As shown, this invention illustrates a cold rolling mill lower support roll mounting device in another embodiment of the present invention, comprising: an adjustable support mechanism 4, the adjustable support mechanism 4 including a groove 41, the groove 41 being formed on the side of a fixed block 35, a telescopic rod 42 being fixedly connected to the top of the threaded block 34, a support plate 43 being fixedly connected to the end of the telescopic rod 42 away from the threaded block 34, and a contact plate 44 being fixedly connected to the top of the support plate 43. The purpose of this design is to effectively support the support roll 2 and prevent it from shaking.

[0039] In some examples, a connecting spring 45 is fixedly connected to the inner wall of the groove 41, and a limiting block 46 is fixedly connected to the end of the connecting spring 45 away from the groove 41. The design of the limiting block 46 is conducive to the effective control of the support plate 43.

[0040] The side section of the support plate 43 is set to L-shape, and the contact plate 44 is in contact with the support roller 2. The design of the contact plate 44 helps to prevent the support roller 2 from moving downward due to gravity.

[0041] The side section of the limiting block 46 is set to arc shape. The limiting block 46 is in contact with the support plate 43. The design of the limiting block 46 and the support plate 43 is conducive to easy operation by the staff.

[0042] The number of limiting blocks 46 is set to two sets, and they are arranged linearly on the inner sidewall of the groove 41. The support plate 43 is located inside the groove 41. The above design is conducive to better support of the support roller 2.

[0043] For example, such as Figures 1-5 As shown, when the diameter of the support roller 2 is too large or too small, and the contact plate 44 cannot effectively support the support roller 2, the operator presses or pulls the support plate 43, causing the support plate 43 to press against the limiting block 46 fixed at the other end of the connecting spring 45. At this time, the support plate 43 presses against the arc surface of the limiting block 46, and at the same time, the connecting spring 45 fixed to the inner wall of the groove 41 is compressed and contracts. When the connecting spring 45 contracts, it drives the limiting block 46 to move and no longer contact the support plate 43, releasing the limitation on the limiting block 46. At the same time, when the support plate 43 moves, it drives the telescopic rod 42 fixed to the top of the threaded block 34 to extend and retract. When the support plate 43 is adjusted so that the contact plate 44 contacts the support roller 2 for effective support, the operator no longer presses or pulls the support plate 43. At this time, the connecting spring 45 is no longer compressed and resets according to its own elasticity, thereby driving the limiting block 46 to reset and limiting the support plate 43 again.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
