Technical Field

[0001] This utility model relates to the field of tension straightening machine technology, and in particular to a pre-straightening system. Background Technology

[0002] In the metal processing industry, tension bending straightening machines are widely used. These machines are straightening devices developed to meet the high straightness requirements of strip materials. They achieve straightness by causing the strip to plastically elongate under the combined action of tension rollers and continuous, alternating bending of bending rollers.

[0003] Because the degree and direction of bending of materials are different, the straightening effect will be inconsistent when the material is straightened by the tension leveler, which will affect the straightening effect. Utility Model Content

[0023] Example

[0024] Please see Figures 1 to 4This application provides a pre-straightening system. The pre-straightening system includes a lower base plate 1, an upper top cover 2, an opening / closing drive device 3, and several pre-straightening modules 4. The lower end of the opening / closing drive device 3 is fixedly connected to the lower base plate 1, and the upper top cover 2 is located above the lower base plate 1, with one end connected to the output end of the opening / closing drive device 3. Each pre-straightening module 4 includes a first straightening roller group 41 and a second straightening roller group 42, which are respectively positioned opposite each other on the lower base plate 1 and below the upper top cover 2. When the upper top cover 2 is pressed down, a straightening gap is formed between the first straightening roller group 41 and the second straightening roller group 42. During operation, the material passes through the straightening gap sequentially, and the opening / closing drive device 3 drives the upper top cover 2 to press down, compressing the material into a uniform bending shape, thus completing the pre-straightening.

[0025] In some embodiments, the pre-straightening system of this application includes three pre-straightening modules 4 that are rotated at intervals.

[0026] The first straightening roller group 41 includes a first roller group support 411, at least three first pressure rollers 412 and at least two first working rollers 413; the first roller group support 411 is fixed to the side of the upper top cover 2 facing the lower bottom plate 1, the first pressure rollers 412 are arranged parallel to each other on the first roller group support 411, and the first working rollers 413 are arranged parallel to the first pressure rollers 412 on the outside of the first roller group support 411 opposite to the first pressure rollers 412, and each first working roller 413 abuts against the two adjacent first pressure rollers 412. The second straightening roller group 42 includes a second roller group support 421, at least two second pressure rollers 422, and at least one second working roller 423. The second roller group support 421 is fixed to the side of the lower base plate 1 facing the upper top cover 2. The second pressure rollers 422 are arranged parallel to each other on the second roller group support 421. The second working rollers 423 are arranged parallel to the second pressure rollers 422 on the outer side of the second roller group support 421, opposite to the second pressure rollers 422. Each second working roller 423 abuts against two adjacent second pressure rollers 422. Further, when the upper top cover 2 rotates to a position parallel to the lower base plate 1, the first working roller 413 of the first straightening roller group 41 and the second working roller 423 of the second straightening roller group 42 are staggered and facing each other. When the pre-straightening system is working, pressure is indirectly provided to the working rollers through the pressure rollers, which makes the rotation of the working rollers smoother; and the staggered and facing working rollers can improve the compression efficiency of the material.

[0027] In some embodiments, the first straightening roller group 41 includes three first pressure rollers 412 and two first work rollers 413, and the second straightening roller group 42 includes two second pressure rollers 422 and one second work roller 423.

[0028] Furthermore, the pre-straightening system in this embodiment of the application also includes several fine-tuning modules 5. The fine-tuning modules 5 are located above the lower base plate 1 or below the upper top cover 2. The first straightening roller group 41 or the second straightening roller group 42 is connected to the lower base plate 1 or the upper top cover 2 through the fine-tuning modules 5. The fine-tuning modules 5 are used to fine-tune the distance between the first straightening roller group 41 and the second straightening roller group 42.

[0029] Furthermore, the fine-tuning module 5 includes a first wedge block 51, a second wedge block 52, and an adjusting handwheel 53. Both the first wedge block 51 and the second wedge block 52 have an inclined slope. A receiving groove is provided on the lower base plate 1 or the upper top cover 2. A first sliding engagement member is provided at the bottom of the receiving groove. The first wedge block 51 is engaged with the first sliding engagement member, allowing the first wedge block 51 to slide along the receiving groove. The slope of the first wedge block 51 faces outward from the receiving groove. The second wedge block 52 can be slidably inserted into the receiving groove, with its slope abutting against the slope of the first wedge block 51. The adjusting handwheel 53 is connected to the first wedge block 51; rotating the adjusting handwheel 53 causes the first wedge block 51 to slide within the receiving groove. The first straightening roller group 41 or the second straightening roller group 42 is connected to the second wedge block 52. When the first wedge block 51 slides in the receiving groove, the slope of the second wedge block 52 abuts against the slope of the first wedge block 51, and the first wedge block 51 can provide an upward thrust to the second wedge block 52, causing the second wedge block 52 to slide up and down, driving the first straightening roller group 41 or the second straightening roller group 42 to move up and down, thereby finely adjusting the distance between the first straightening roller group 41 and the second straightening roller group 42.

[0030] In this embodiment, the fine-tuning module 5 is disposed on the lower base plate 1, and the first straightening roller group 41 or the second straightening roller group 42 is connected to the lower base plate 1 through the fine-tuning module 5.

[0031] The pre-straightening system of this application embodiment can compress materials with different degrees of curvature or different curvature directions into a uniform curvature form, reducing the working pressure of the straightening module and improving the straightening efficiency. Furthermore, the pre-straightening system of this application embodiment can also fine-tune the straightening gap of each pre-straightening module 4, thereby adapting to different types of materials.

[0032] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
