Description

Technical Field

[0001] This application relates to the field of laser cutting technology, and more particularly to a cutting device. Background Technology

[0002] A related technology (announcement number: CN221984174U) discloses a cutting device for sheet metal processing, including a processing table, a through hole, a storage box, a control panel, a positioning plate, a variable frequency motor, a two-way lead screw, a slider, a support plate, a sleeve, a cylinder, a clamping plate, an anti-slip pad, a guide plate, a housing, a first linear motor, a second linear motor, an electric telescopic rod, and a laser cutting device body.

[0003] In the process of implementing the technical solution disclosed herein, at least the following problems were found in the related technologies:

[0004] The sheet metal cutting device, driven by a variable frequency motor, changes the distance between the two clamping plates and the two clamping sleeves. Then, driven by the two cylinders, the clamping plates clamp the sheet metal part placed in the clamping sleeves, allowing for surface cutting. However, once the sheet metal part is clamped and fixed, the angle cannot be adjusted. Therefore, when cutting different surfaces of the sheet metal part, it must be re-clamped, resulting in wasted time and effort and reduced cutting efficiency.
