Description

Technical Field

[0001] The present invention relates to the technical field of mechanical equipment, and more specifically, to a working roll bearing seat assembly, and also to a tension straightening machine including the working roll bearing seat assembly. Background Art

[0002] The air cushion furnace is one of the important equipment of the finishing line, and the stretching and bending straightening is the most important equipment of the machine series. Due to the complex product structure and the lack of cutting head during production, the roll surface of the working roll is easily damaged and needs to be replaced regularly, and the bearings are often replaced as well. The design of the bearing seat deviates from the actual bearing, and the groove on the end face of the bearing seat is smaller than the outer diameter of the thrust bearing of the combined bearing; the bearing oiling hole is not offset from the bearing oiling groove, resulting in a loose fit between the bearings, and the bearings are often stuck in the bearing seat due to the offset of the bearing position during the working process, which increases the roll changing time and affects the production progress.

[0003] In summary, how to effectively solve the problem that the working roll bearing is difficult to separate from the bearing seat is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0004] In view of this, the first object of the present invention is to provide a working roll bearing seat assembly, which can effectively solve the problem that the working roll bearing is difficult to separate from the bearing seat.

[0021] The embodiment of the present invention discloses a working roll bearing seat assembly, which can effectively solve the problem that the working roll bearing is difficult to separate from the bearing seat.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1 , Figure 1 A schematic diagram of the partial cross-sectional structure of a working roll bearing seat assembly after installation provided in an embodiment of the present invention.

[0024] In a specific embodiment, this embodiment provides a working roll bearing seat assembly. Specifically, the working roll bearing assembly includes a seat body 1 and a top piece 2.

[0025] The seat body 1 is provided with a bearing hole 11, so that the corresponding end of the working roll 3 with the support bearing 4 can be inserted into the bearing hole 11 to be supported by the bearing hole 11, wherein the radial support portion of the support bearing 4 is located in the bearing hole 11 and supported by the hole wall of the bearing hole 11. The bearing hole 11 is generally a cylindrical hole, which can be composed of cylindrical holes of different diameters or a cylindrical hole of a single diameter.

[0026] For the convenience of description in the context, the side toward which the opening of the bearing hole 11 is facing can be referred to as the positive direction, and correspondingly, the direction opposite to the positive direction can be referred to as the reverse direction. That is, the bearing hole 11 is provided on the seat body 1, which can be described as the bearing hole 11 is provided on the positive side of the seat body 1, and the bearing hole 11 is provided on the positive side, which means that the opening of the bearing hole 11 is located on the positive side of the seat body 1 and faces the positive side.

[0027] Among them, the back side of the seat body 1 is provided with a mounting through hole 12 that penetrates into the bearing hole 11, and the top piece 2 is inserted into the mounting through hole 12 and can move axially along the bearing hole 11, so as to be able to axially push the working roller 3 installed in the bearing hole 11. Of course, correspondingly, the outer end of the top piece 2 should be exposed from the seat body 1, so that the staff can apply an impact force to the top piece 2 from the back side of the seat body 1 to the positive direction, so that the top piece 2 can transmit the impact force to the working roller 3. The structural shape of the mounting through hole 12 is not limited, so long as the top piece 2 can be inserted into the mounting through hole 12, and it is convenient for the top piece 2 to move axially along the bearing hole 11 in the mounting through hole 12.

[0028] In the working roll bearing seat assembly, when in use, the corresponding end of the working roll 3 with the support bearing 4 can be inserted into the bearing hole 11 to be supported by the bearing hole 11, wherein the radial support portion of the support bearing 4 is located in the bearing hole 11 and supported by the hole wall of the bearing hole 11. When the working roll 3 needs to be removed, it is only necessary to apply an impact force to the top piece 2 from the back side of the seat body 1, that is, to knock the top piece 2 so that the top piece 2 hits the working roll 3, and the working roll 3 is subjected to a large impact force and can be easily withdrawn from the bearing hole 11. In the working roll bearing seat assembly, a mounting through hole 12 is opened on the back side of the seat body 1, so that the top piece 2 can pass through the mounting through hole 12, and then the impact force can be transmitted to the working roll 3 by hitting the top piece 12 to push out the working roll 3, so the overall operation is simple and convenient. In summary, the working roll bearing seat assembly can effectively solve the problem that the working roll bearing is difficult to detach from the bearing seat.

[0029] Furthermore, considering that the bearing hole 11 generally needs to be filled with lubricating oil, in order to avoid the lubricating oil from overflowing, the inside of the top piece 2 can be sealed and connected with the bearing hole 11, but the diameter of the bearing hole 11 is relatively large, and sealing is difficult. Based on this, it is preferred that the top piece 2 and the mounting through hole 12 are sealed and matched. Specifically, an annular sealing ring 7 is provided between the top piece 2 and the hole wall of the mounting through hole 12, and an annular receiving groove for accommodating the annular sealing ring 7 can be provided on the hole wall of the mounting through hole 12, or an annular receiving groove for accommodating the annular sealing ring 7 can be provided on the top piece 2.

[0030] Furthermore, in order to better push the working roll 3 and avoid damage to the end face of the working roll 3, it is preferred that the top member 2 here includes a column 21 matched with the mounting through hole 12 and a top plate 22 mounted on the inner end of the column 21, and the outer diameter of the top plate 22 is larger than the outer diameter of the column 21. Of course, the column 21 can be a cylindrical part or a prism part, such as a square column part or a triangular prism part. The diameter of the top plate 22 is larger than the diameter of the column 21, so that it has a larger contact surface with the working roll 3. Preferably, the outer radius of the top plate 22 can be equal to the inner radius of the bearing hole 11, such as a clearance fit between them. At this time, an annular sealing ring can be set between the top plate 22 and the bearing hole 11, or an annular sealing ring 7 can be set between the column 21 and the mounting through hole 12.

[0031] Furthermore, in order to better protect the working roll 3, it is preferred that an elastic component 5 is also included here, which is located in the bearing hole 11 and abuts against the bottom of the bearing hole 11 to perform elastic deformation in the axial direction. It should be noted that the elastic component 5 abuts against the bottom of the bearing hole 11, which can be directly or indirectly abutted, subject to the support being obtained from the bottom of the bearing hole 11, and can be directly or indirectly abutted against the end face of the working roll 3. For example, it can be arranged between the top plate 22 and the end face of the working roll 3; it is preferred that the elastic component 5 is sleeved on the column 21 of the top member 2, and the two sides are respectively abutted against the bottom of the bearing hole 11 and the top plate 22 of the top member 2, wherein the top plate 22 of the top member 2 is as described above, that is, used to abut against the end face of the working roll 3. The elastic component 5 is such as a columnar spring or a tubular elastomer. In order to ensure the resistance, it is preferred that the elastic component 5 is a disc spring, that is, the disc spring is sleeved on the column 21 of the top member 2.

[0032] Further, it is preferred that the bearing hole 11 is a cylindrical hole, and the diameter is equal from the positive side of the seat body 1 to the inner end surface of the top member 2, so that the radial support portion of the support bearing 4 is located in the bearing hole 11, and the axial support portion cannot enter the bearing hole 11 and is located on the positive side of the seat body 1. Specifically, the diameter of the bearing hole 11 can be equal from the hole mouth to the hole bottom.

[0033] Based on the working roll bearing seat assembly provided in the above embodiments, the present invention further provides a straightening device, which includes any one of the working roll bearing seat assemblies in the above embodiments, and also includes a working roll 3 and a support bearing 4 sleeved on the end of the working roll 3, wherein the radial support portion of the support bearing 4 is located in the bearing hole 11 of the working roll bearing seat assembly and supported by the hole wall of the bearing hole 11, and the top piece 2 of the working roll bearing seat assembly can abut against the end surface of the working roll 3 to push the working roll 3 outward. Since the straightening device adopts the working roll bearing seat assembly in the above embodiments, please refer to the above embodiments for the beneficial effects of the straightening device.

[0034] Further, it is preferred that the axial support portion of the support bearing 4 is located outside the bearing hole 11, and the two sides are respectively against the front of the seat body 1 of the working roll bearing seat assembly and against the shoulder of the working roll 3 through the elastic device 6. The elastic device 6 can also be a butterfly spring. By locating the axial support portion outside the bearing hole, it is possible to better prevent the axial support portion from being stuck in the orifice of the bearing hole 11.

[0035] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
