Description

Technical Field

[0001] This utility model relates to the field of cold-rolled steel strip technology, specifically to an automatic tension adjustment device for cold-rolled steel strip. Background Technology

[0002] Cold-rolled steel strip is made from hot-rolled strip and sheet as raw materials, rolled into strip and sheet by a cold rolling mill at room temperature. It plays an important role in industrial manufacturing. However, during the processing of cold-rolled steel strip, uneven unfolding and excessive or insufficient tension often occur after the coiled strip is unrolled. Therefore, tension adjustment is necessary to ensure the quality of subsequent strip processing. Existing strip tension control devices can only adjust the tension of the steel strip in one direction, which limits the adjustment direction and cannot meet the current tension adjustment requirements of steel strip.

[0003] For example, CN203917404U discloses a strip tension control device between stands in a cold continuous rolling mill, which consists of a front tension detection device, a tension adjustment device, and a rear tension detection device. The front tension detection device includes a front tension roller and two tension sensors, which are located below the bearing seats at both ends of the front tension roller and are used to detect the tension of the strip at the front tension roller. During operation, the tension of the strip can only be adjusted in one direction, which limits the adjustment direction and cannot meet the tension adjustment requirements of existing strips. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an automatic tension adjustment device for cold-rolled steel strip, which has the advantages of good adjustment effect.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an automatic tension adjustment device for cold-rolled steel strip, comprising a base, characterized in that a fixed frame is provided at the upper right end of the base, a clamping hydraulic push rod is provided on the upper side of the fixed frame, the output end of the clamping hydraulic push rod passes through the fixed frame and is connected to a clamping piece, a bearing seat corresponding to the clamping piece is provided on the base below the fixed frame, and an assembly seat is provided in the middle of the upper side of the base;

[0006] The upper side of the assembly base is provided with a pair of first frames, a pair of second frames, and a pair of third frames. The first, second, and third frames are symmetrically distributed on the assembly base. A traction component is provided on the upper left side of the base. An adjusting hydraulic push rod is provided between each pair of first, second, and third frames. The output end of the adjusting hydraulic push rod is connected to a lifting frame. An adjusting roller group is provided on the lifting frame.

[0007] In the above scheme, the traction assembly includes an assembly frame disposed on the upper side of the base, a pair of traction rollers disposed on the inner side of the assembly frame, a gear disposed at one end of the pair of traction rollers, and a drive component connected to the other end of one of the traction rollers.

[0008] In the above scheme, the middle part of the bearing seat is provided with a groove, and a fixing plate is provided on the upper side of the groove.

[0009] In the above scheme, the inner walls of the first frame, the second frame and the third frame are all provided with strip grooves, and guide rods are provided inside the strip grooves. The two sides of the lifting frame are slidably connected to the guide rods.

[0010] The automatic tension adjustment device for cold-rolled steel strip provided by this utility model has the following beneficial effects: 1. By adding a pair of first frames, a pair of second frames and a pair of third frames on the upper side of the base, and cooperating with adjusting hydraulic push rods, lifting frames and adjusting rollers, the cold-rolled steel strip can be stretched in multiple directions. With the traction component, the tension adjustment effect can be increased to meet the actual tension adjustment needs.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Example 1

[0018] Please see Figure 1-3An automatic tension adjustment device for cold-rolled steel strip includes a base 1, a fixed frame 2 at the upper right end of the base 1, and a portal frame 3. A clamping hydraulic push rod 3 is mounted on the upper side of the fixed frame 2, with its output end penetrating the top plate of the fixed frame 2 and connected to a clamping plate 4. A bearing seat 5 corresponding to the clamping plate 4 is mounted on the base 1 below the fixed frame 2. A groove is provided in the middle of the bearing seat 5, and a fixing plate 17 is mounted on the upper side of the groove. A guide slope is formed on the upper side of the inner wall of the groove of the bearing seat 5.

[0019] An assembly seat 6 is located on the upper center of the base 1. From right to left, a pair of first frames 7, a pair of second frames 8, and a pair of third frames 9 are arranged on the upper side of the assembly seat 6. A traction assembly is located at the upper left end of the base 1. The pair of first frames 7, second frames 8, and third frames 9 are respectively supported front and rear on the assembly seat 6. That is, the two first frames of the pair of first frames 7 are respectively located on the front and rear sides of the assembly seat 6, and so on. Adjustable hydraulic push rods 10 are provided between the pair of first frames 7, the pair of second frames 8, and the pair of third frames 9. The output end of the adjustable hydraulic push rods 10 is connected to a lifting frame 11, and the lifting frame 11 is equipped with an adjusting roller group 12. Specifically, the lifting frame 11 is a U-shaped frame, located between the front and rear first frames, second frames, and third frames. Two adjusting rollers 12 are provided between the two vertical legs of each lifting frame 11, and the two adjusting rollers 12 are arranged vertically. The inner walls of the first frame 7, the second frame 8, and the third frame 9 are all provided with strip grooves, and guide rods 18 are installed inside the strip grooves. The two sides of the lifting frame 11 are slidably connected to the guide rods 18 to increase the stability of the lifting frame 11 during the lifting process.

[0020] The traction assembly includes an assembly frame 13, on the inner side of which a pair of vertically distributed traction rollers 14 are arranged. The assembly frame 13 is composed of front and rear vertical supports, and the pair of traction rollers 14 are arranged between the vertical supports. Each pair of traction rollers 14 has a gear 15 at one end, and the other end of one of the traction rollers 14 is connected to a drive unit 16. The drive unit 16 is a motor plus a reducer, which is a conventional design.

[0021] During the processing of cold-rolled steel strip, uneven unfolding, excessive or insufficient tension often occurs after the coiled strip is unwound. Therefore, tension adjustment is necessary to ensure the quality of subsequent strip processing. At this time, the operator can pass one side of the cold-rolled steel strip through the adjusting roller group 12 inside the fixed frame 2, a pair of first frames 7, a pair of second frames 8, and a pair of third frames 9 respectively, and then insert one side of the cold-rolled steel strip between a pair of traction rollers 14.

[0022] Then, the clamping hydraulic push rod 3 is controlled to move, driving the clamping plate 4 to descend. Together with the bearing seat 5 and the fixing plate 17, the other side of the cold-rolled strip can be clamped and fixed. Subsequently, the adjusting hydraulic push rod 10 located between a pair of first frames 7, a pair of second frames 8 and a pair of third frames 9 is operated. Together with the lifting frame 11 and the adjusting roller group 12, the cold-rolled strip can be stretched in multiple directions, thereby enabling automatic tension adjustment.

[0023] After the tension adjustment is completed, the drive component 16 operates, the clamping hydraulic push rod 3 is reset, and the drive component 16, together with the gear 15 and the traction roller 14, can drive the cold-rolled strip steel after the tension adjustment is completed to move. At the same time, it can roll the surface of the cold-rolled strip steel to prevent unevenness on the surface of the cold-rolled strip steel after the tension adjustment is completed, which facilitates the subsequent processing of the cold-rolled strip steel.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
