Description

Technical Field

[0001] The utility model relates to the field of strip steel production and processing, in particular to a stretching and straightening device for cold-rolled strip steel production. Background Art

[0002] Stretch straightening is an important process step in the production of cold-rolled strip steel, which aims to improve the surface quality of the strip steel, reduce the plate shape deviation and improve the mechanical properties of the product. After the cold-rolled strip steel is processed in the previous process, it enters the stretch straightening device through the conveying system. Relying on a set of rollers or drums, tensile forces in different directions are applied to make the strip steel plastically deformed and adjust its shape and size. During this process, the rollers or drums will produce huge friction with the surface of the strip steel, causing the surface of the strip steel to become more fragile. During the subsequent process operations, the continued huge friction force can easily cause the strip steel to be significantly damaged, increasing the risk of strip steel damage.

[0003] Therefore, a tensile straightening device for cold-rolled strip production is now developed in response to the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of existing devices that generate huge friction with the surface of the strip during processing, causing the surface of the strip to become more fragile, and the continued huge friction in subsequent operations can easily cause obvious breakage of the strip, increasing the risk of strip damage, the utility model provides a stretching and straightening device for cold-rolled strip production.

[0005] The technical implementation scheme of the present utility model is: a tensile straightening device for cold-rolled strip production, comprising a mounting frame, an upper portion of the mounting frame being rotatably and slidingly connected to a straightening roller, a lower portion of the mounting frame being also rotatably connected to the straightening roller, the upper sides of both the front and rear portions of the mounting frame being connected to a lifting assembly by bolts, the lifting assembly being rotatably connected to the straightening roller on the upper side, and a lubrication mechanism being provided on the mounting frame for lubricating the strip to avoid damage caused by excessive friction.

[0006] Furthermore, the lubrication mechanism includes a fixed frame, the fixed frame is connected between the front and rear sides of the right part of the installation frame by bolts, two rotating rollers are rotatably connected to the fixed frame, and the rotating rollers are each provided with an adsorption part, the front side of the fixed frame is connected to a liquid inlet pipe, the right side of the fixed frame is connected to a spray assembly, and the spray assembly is connected to two liquid pumps.

[0007] Furthermore, an adaptation mechanism is also included, which includes a connecting frame, and the front and rear sides of the left part of the installation frame are connected to the connecting frame by bolts. A rotating plate is rotatably provided on the connecting frame, and a support roller is rotatably connected between the left parts of the rotating plates. A torsion spring is connected between the rotating plate and the adjacent connecting frame.

[0008] Furthermore, the lower end of the lifting assembly is connected to the installation frame in a through-type manner.

[0009] Furthermore, the liquid inlet pipe is provided with a clamping ring.

[0010] Furthermore, the spray assembly includes a connecting pipe, a supporting pipe and a nozzle. The supporting pipe is connected to the upper part of the fixed frame. Two connecting pipes are connected between the right side of the supporting pipe and the fixed frame. Four nozzles are connected to the supporting pipe.

[0011] By adopting the above technical solution, the utility model has the following advantages:

[0012] 1. The utility model processes the strip steel by a contact friction straightening method, which will cause the surface of the strip steel to be worn. Therefore, the lubricating oil is absorbed by the adsorption part to lubricate the strip steel after the stretching straightening, making the strip steel surface smoother, reducing the friction force on the strip steel in subsequent operations, and preventing the strip steel from being damaged due to excessive friction.

[0013] 2. The utility model relies on support rollers to support the bottom of the strip at the feeding position, so that the strip can be in a horizontal state before feeding, reducing bending damage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0019] Example 1

[0020] A tensile straightening device for cold rolled strip production, such as Figure 1 As shown, it includes a mounting frame 1, the upper part of the mounting frame 1 is rotatably and slidingly connected to the straightening roller 2, the lower part of the mounting frame 1 is also rotatably connected to the straightening roller 2, the upper sides of the front and rear parts of the mounting frame 1 are connected to the lifting components 3 by bolts, the lower end of the lifting component 3 is connected to the mounting frame 1 through-type, the lifting component 3 is rotatably connected to the straightening roller 2 on the upper side, and the mounting frame 1 is provided with a lubrication mechanism 4 for lubricating the strip to avoid damage caused by excessive friction.

[0021] like Figure 1 and Figure 2 As shown, the lubrication mechanism 4 includes a fixed frame 41, and the fixed frame 41 is connected between the front and rear sides of the right side of the installation frame 1 by bolts. Two rotating rollers 42 are rotatably connected to the fixed frame 41, and the rotating rollers 42 are each provided with an adsorption member 43. The front side of the fixed frame 41 is connected to a liquid inlet pipe 44, and the liquid inlet pipe 44 is provided with a clamping ring. The right side of the fixed frame 41 is connected to a spray assembly 45, and the spray assembly 45 is connected to two liquid pumps 46. The spray assembly 45 includes a connecting pipe, a support pipe and a nozzle. The upper part of the fixed frame 41 is connected to the support pipe, and two connecting pipes are connected between the right side of the support pipe and the fixed frame 41, and four nozzles are connected to the support pipe.

[0022] It should be noted that the strip needs to be stretched and straightened after production is completed. At this time, this device can be used for operation. First, the lifting component 3 is controlled to drive the upper straightening roller 2 to slide upward to provide sufficient space for the strip to pass through. After the strip passes between the straightening rollers 2, the strip is continued to be pushed to move so that the strip passes between the rotating rollers 42 again. Then the lifting component 3 is controlled to drive the upper straightening roller 2 to reset. After the reset is completed, the straightening roller 2 is connected to the drive device, and then the drive device is started. After the drive device is started, it will drive the straightening roller 2 to rotate in the opposite direction, thereby The strip is stretched and straightened. During this process, the operator can simultaneously start the liquid pump 46. The liquid pump 46 draws out the lubricating oil in the fixed frame 41, so that the lubricating oil is sprayed on the upper adsorption part 43 through the spray assembly 45. Since the rotating roller 42 on the lower side is in the fixed frame 41, the bottom position of the lower adsorption part 43 will directly contact the lubricating oil, so that the lubricating oil is attached. Finally, the lubricating oil is applied to the strip by relying on the adsorption part 43, so that the friction force received by the strip after the stretching and straightening is completed is reduced, thereby preventing the strip from being damaged due to excessive friction and causing losses.

[0023] Example 2

[0024] On the basis of Example 1, Figure 1 and Figure 3As shown, an adaption mechanism 5 is also included, and the adaption mechanism 5 includes a connecting frame 51. The front and rear sides of the left part of the installation frame 1 are connected to the connecting frame 51 by bolts. A rotating plate 52 is rotatably provided on the connecting frame 51, and a support roller 53 is rotatably connected between the left parts of the rotating plate 52. A torsion spring 54 is connected between the rotating plate 52 and the adjacent connecting frame 51.

[0025] It should be noted that during the strip feeding process, there is a lack of effective support points at the strip feeding position, which will cause the strip to fall before feeding. At this time, the support roller 53 and the rotating plate 52 are used to support the bottom of the strip at the feeding position, so that the strip can be in a horizontal state before feeding, reducing bending damage.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
