Technical Field

[0001] This utility model relates to the field of threaded steel cutting technology, specifically to a threaded steel cutting device. Background Technology

[0002] Rebar cutting equipment is a type of rebar cutting machine specifically designed for processing ribbed rebar. Its main function is to cut rebar into specific lengths according to engineering requirements. It is widely used in construction sites, bridge and tunnel construction, rebar processing centers, and waste recycling. The utility model CN222536209U discloses a threaded steel cutting device, including an installation frame. A support base is fixedly installed on the bottom inner wall of the installation frame. Connecting seats are fixedly installed on the left and right sides of the support base. A first motor is fixedly installed on the left inner wall of the connecting seat. A first lead screw is fixedly installed at the output end of the first motor. The device is equipped with a clamping assembly. The above technical solution involves a first motor driving a first lead screw to rotate, which in turn drives a sliding block and a fixed frame to move in opposite directions, placing the threaded steel bar above the support base. A second motor is then controlled to drive a second lead screw to rotate, which in turn drives a slider and a clamping block to move in opposite directions, allowing the clamping block to clamp and fix the threaded steel bar. This makes clamping the threaded steel bar more convenient and allows for cutting threaded steel bars of different lengths. However, the cutting device cannot simultaneously cut multiple threaded steel bars. When cutting threaded steel bars of different lengths, a measuring tape is required for length measurement and adjustment. Rewinding the measuring tape is time-consuming and time-consuming, preventing rapid length adjustment for continuous cutting. Utility Model Content
