AI Technical Summary
The existing single-layer rubber-coated structure of the rolling mill ironing rolls has a fixed hardness, which makes it easy to deform and increase friction when the rubber layer is too soft, resulting in decreased wear resistance. When it is too hard, it causes impact vibration, resulting in difficulties in plate shape control and short service life.
It adopts a double-layer adhesive structure from the inside out, consisting of a buffer adhesive layer and a rigid adhesive layer. The hardness of the buffer adhesive layer is less than that of the rigid adhesive layer. The buffer rigid adhesive layer is in rigid contact with the metal plate. The rigid adhesive layer is used to press and roll the metal plate, while the buffer adhesive layer is used to buffer impact. The fiber reinforcement layer disperses stress, forming a fully encapsulated structure to protect the buffer adhesive layer.
It effectively buffers rigid contact impacts, reduces friction, extends service life, improves wear resistance and rolling capacity, and ensures the stability of plate shape control and finished product quality.

Abstract
Description
Technical Field
[0001] This application relates to the field of rubber roller technology, and in particular to a rubber layer structure for a rolling mill ironing roller. Background Technology
[0002] As a key process roll in the rolling production of sheet metal, the performance of mill screed rolls directly determines the surface quality and rolling stability of the sheet metal. Currently, most mill screed rolls in the industry use a single-layer rubber-coated structure. The single-layer rubber-coated structure has poor adaptability due to its fixed hardness. When the rubber layer is too soft, the roll surface is prone to deformation, leading to increased friction, decreased wear resistance, difficulty in sheet shape control, and a short service life. Conversely, when the rubber layer is too hard, rigid contact can cause impact vibration, resulting in uneven sheet metal thickness and defects such as edge waviness.
[0003] Therefore, the applicant intends to propose a rubber layer structure for a rolling mill ironing roll to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a rubber layer structure for a rolling mill ironing roll. This rubber layer structure is softer from the inside out, which can buffer the rigid contact between the rigid rubber layer and the metal plate to be rolled, and also reduce the friction with the metal plate, thereby extending the service life.
[0005] To achieve the above objectives, the solution of this utility model is: a rubber layer structure for a rolling mill ironing roll, comprising an ironing roll shaft, an ironing roll shaft journal, a buffer rubber layer, and a rigid rubber layer;
[0006] The ironing roller shaft has protruding ironing roller shaft necks at both ends, which are used to be installed in conjunction with the ironing mill.
[0007] The buffer adhesive layer is sleeved on the roller surface of the ironing roller shaft, and the rigid adhesive layer is sleeved on the buffer adhesive layer. The hardness of the buffer adhesive layer is less than that of the rigid adhesive layer. The rigid adhesive layer is used to press and roll the metal plate, and the buffer adhesive layer is used to buffer the impact generated when the rigid adhesive layer and the metal plate are in rigid contact.
[0008] Preferably, the rigid adhesive layer extends to both ends to wrap around the non-contact area between the buffer adhesive layer and the ironing roller shaft, forming a fully enclosed structure.
[0009] Preferably, one end of the rigid adhesive layer extends in a direction close to the axis to form an inner flange, which is used for mounting and positioning the rigid adhesive layer on the buffer adhesive layer.
[0010] Preferably, the buffer layer is PU foam particles, and the rigid layer is nitrile rubber.
[0011] Furthermore, the rigid adhesive layer has a first snap-fit portion at both ends and a snap-fit ring. The snap-fit ring covers the same end face of the buffer adhesive layer and the rigid adhesive layer. The contact surface between the snap-fit ring and the rigid adhesive layer has a second snap-fit portion. The second snap-fit portion of the snap-fit ring engages with the first snap-fit portion of the rigid adhesive layer. The snap-fit ring is used to protect the end faces of the buffer adhesive layer and the rigid adhesive layer.
[0012] Furthermore, the thickness of the buffer adhesive layer is greater than or equal to the thickness of the rigid adhesive layer.
[0013] Furthermore, a fiber reinforcement layer is provided between the buffer adhesive layer and the rigid adhesive layer, and the fiber reinforcement layer is used to disperse the stress of the buffer adhesive layer.
[0014] Furthermore, the length of the buffer adhesive layer is greater than the width of the metal plate to be rolled.
[0015] After adopting the above solution, the gain effect of this utility model is as follows:
[0016] 1. Buffering the rigid contact of the metal sheet to be rolled. The buffer rubber layer is located between the ironing roller and the rigid rubber layer. When the ironing roller drives the rigid rubber layer to contact the metal sheet, the buffer rubber layer buffers the impact generated by the rigid contact between the rigid rubber layer and the metal sheet, so that the rigid rubber layer will not make hard contact with the metal sheet, causing the metal sheet to deform.
[0017] 2. Reduced friction and thus extended service life. Due to its high hardness, the rigid adhesive layer has less friction with the metal plate, good wear resistance, and thus extended device service life. At the same time, the high hardness of the rigid adhesive layer also provides better rolling ability, making it easier to control the shape of the rolled metal plate and resulting in good finished product quality.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0031] It should be noted that the terms "first," "second," "third," "fourth," and "fifth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0032] like Figure 1 As shown, a rubber layer structure for a rolling mill ironing roll includes an ironing roll shaft 1, an ironing roll shaft journal 2, a buffer rubber layer 3, and a rigid rubber layer 4; the ironing roll shaft 1 has ironing roll shaft journals 2 protruding from both ends, and the ironing roll shaft journals 2 are used to cooperate with the ironing rolling mill for installation.
[0033] The buffer adhesive layer 3 is sleeved on the roller surface of the ironing roller 1, and the rigid adhesive layer 4 is sleeved on the buffer adhesive layer 3. The hardness of the buffer adhesive layer 3 is less than that of the rigid adhesive layer 4. The rigid adhesive layer 4 is used to press and roll the metal plate, and the buffer adhesive layer 3 is used to buffer the impact generated when the rigid adhesive layer 4 comes into rigid contact with the metal plate.
[0034] The high hardness of the rigid adhesive layer 4 significantly reduces the coefficient of friction with the metal sheet, thereby improving wear resistance and directly extending the service life of the equipment. Simultaneously, the high hardness of the rigid adhesive layer 4 also ensures good rolling performance, guaranteeing the stability of the metal sheet forming process, making the sheet shape easier to control precisely, and ultimately obtaining higher quality finished products.
[0035] The buffer layer 3 of this application is located between the ironing roller 1 and the rigid adhesive layer 4. This double-layer adhesive layer design plays a dual buffering role in the rolling process of the metal sheet: when the ironing roller 1 drives the rigid adhesive layer 4 to contact the metal sheet, the buffer layer 3 absorbs the pressure given by the ironing roller 1 through elastic deformation, avoiding direct collision between the rigid adhesive layer 4 and the metal sheet, which would cause deformation of the metal sheet; during the rolling process, the buffer layer 3 can also effectively dissipate the support force transmitted in the reverse direction by the metal sheet, ensuring that the pressure applied to the metal sheet is transmitted evenly and controllably, and guaranteeing the sheet shape quality of the metal sheet.
[0036] The shapes of the cushioning adhesive layer 3 and the rigid adhesive layer 4 can be varied, such as... Figure 2 In one embodiment shown, the rigid adhesive layer 4 extends to both ends to wrap around the non-contact area between the cushioning adhesive layer 3 and the ironing roller shaft 1, forming a fully enclosed structure. Since the cushioning adhesive layer 3 is easily scratched by hard external objects, the outer rigid adhesive layer 4 provides physical protection for the fragile cushioning adhesive layer 3, preventing it from being damaged by external collisions or friction.
[0037] like Figure 3 In one embodiment shown, one end of the rigid adhesive layer 4 extends in a direction close to the axis to form an inner flange 41. During installation, the end of the rigid adhesive layer 4 without the inner flange 41 is first fitted into the buffer adhesive layer 3, and then pushed in axially until the inner flange 41 abuts against the end face of the buffer adhesive layer 3 to complete the assembly. The inner flange 41 can both protect the buffer adhesive layer 3 and serve as an installation reference surface.
[0038] The buffer layer 3 is preferably PU foam particles. PU foam particles have a wide density range; the lower the density, the better the flexibility, and the higher the density, the stronger the compressive strength and durability. In practical applications, PU foam particles of different densities can be selected according to the material of the metal sheet being rolled. In addition, PU foam particles are low in cost and suitable for mass industrial production. The rigid layer 4 is preferably nitrile rubber. Nitrile rubber has good oil resistance and wear resistance, making it suitable for metal sheet rolling applications.
[0039] like Figure 4 In one embodiment shown, the rigid adhesive layer 4 has first snap-fit portions 42 at both ends and a snap-fit ring 6. The snap-fit ring 6 covers the same side end face of the buffer adhesive layer 3 and the rigid adhesive layer 4. The contact surface between the snap-fit ring 6 and the rigid adhesive layer 4 has a second snap-fit portion 61. The second snap-fit portion 61 of the snap-fit ring 6 engages with the first snap-fit portion 42 of the rigid adhesive layer 4. The snap-fit ring 6 is used to protect the end faces of the buffer adhesive layer 3 and the rigid adhesive layer 4.
[0040] As a preferred embodiment, the thickness of the buffer layer 3 is greater than or equal to the thickness of the rigid layer 4. The buffer layer 3 is used to buffer impacts. To save costs, inexpensive buffering materials such as PU foam particles are generally selected. To ensure the buffering effect, it is preferable to increase the thickness of the buffer layer 3. For example, in the case of rolled aluminum plate, the buffer layer 3 is made of 12mm PU foam particles, and the rigid layer 4 is made of 8mm nitrile rubber. At this time, the rolling performance is the best.
[0041] like Figure 5 In one embodiment shown, a fiber reinforcement layer 5 is provided between the buffer adhesive layer 3 and the rigid adhesive layer 4. The fiber reinforcement layer 5 is used to disperse the stress of the buffer adhesive layer 3, prevent the buffer adhesive layer 3 from collapsing, and extend its service life. The fiber reinforcement layer 5 can be made of aramid fiber mesh.
[0042] The length of the buffer adhesive layer 3 is greater than the width of the metal plate to be rolled, so that the rigid adhesive layer 4 that is in direct contact with the metal plate has a buffer adhesive layer 3 to buffer it, the metal plate is subjected to uniform stress and the plate shape quality is good.
[0043] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
