Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a steel bar cutting device for construction engineering. Background Art

[0002] Film is a thin, soft, transparent sheet made of plastic, adhesive, rubber or other materials. The scientific explanation of film is: a two-dimensional material formed by atoms, molecules or ions deposited on the surface of a substrate. In the production process of refrigerators, in order to prevent dust from adhering to the surface of the refrigerator, a layer of film is generally chosen to be pasted on the surface of the refrigerator. However, the sizes of refrigerators are different, so the film needs to be cut before use.

[0003] According to the search, Chinese patent literature, announcement number: CN213256843U, discloses a steel bar cutting device for construction engineering, including a pressure plate device corresponding to the second fixed plate, which increases the clamping force on the upper side, and also provides a slide groove corresponding to the slider, which can better fix the steel bar and make the steel bar cutting effect better. However, the device still has defects during use. After the steel bar is cut, manual unloading is required, which reduces work efficiency and cannot automatically adjust the cutting length. Due to the heavy weight of the steel bar, it is more difficult for personnel to push the steel bar to adjust the cutting length. The cutting blade will generate a lot of heat when cutting the steel bar, and the cutting blade will crack if it is overheated, thereby reducing the service life of the cutting blade.
