Technical Field

[0001] The utility model relates to the technical field of steel strip production, in particular to a guiding device of a fixed-length steel strip shearing machine. Background Art

It can be processed by cold rolling or hot rolling and has the advantages of high dimensional accuracy, good surface quality, easy processing, and material saving. During the production process of steel strip, it is necessary to cut the steel strip according to the customer's specific length requirements. The existing cutting equipment cannot guide the steel strip according to the size of the steel strip during use, and it is easy to cause the steel strip to deviate during the shearing process, thereby affecting the quality of the shear surface, and it is unable to guide the steel strip near the shearing position, affecting the shearing efficiency.

[0003] According to the description of a steel strip shearing machine with a guiding and positioning device published on the patent website (authorization announcement number: CN205869578U), the steel strip shearing machine with a guiding and positioning device includes "a frame, a hydraulic cylinder, an upper cutting knife device", etc. to perform guiding work.

[0004] In view of the above description, the applicant believes that there are the following problems:

It cannot limit the front and rear sides of the steel strip, which will cause the steel strip to deviate, affecting the stability of shearing, and cannot guide the steel strip near the shearing position, affecting the use effect. Therefore, the shearing machine needs to be improved. Utility Model Content
