Technical Field
[0001] This utility model relates to the field of steel cutting technology, specifically a steel cutting device with a pushing structure. Background Technology
[0002] Steel pipe cutting devices are key equipment used for cutting steel pipes in industrial production and construction.
[0003] Chinese patent disclosure (CN106001734A) discloses a steel pipe cutting machine with automatic feeding function. The machine includes a base plate, on the upper surface of which a feeding device and a cutting device are fixedly connected. The cutting device is located to one side of the feeding device. The feeding device includes a first supporting plate with a first connecting rod fixedly connected to its front side. The upper surface of the first connecting rod is fixedly connected to the surface of a dual-axis motor via a second connecting rod. This steel pipe cutting machine with automatic feeding function, by setting up the feeding device, causes the two output shafts of the dual-axis motor to drive the first feeding wheel and the drive wheel to rotate forward, respectively. The drive wheel drives the driven wheel to rotate via a conveyor belt, causing the second feeding wheel to rotate forward. This moves the steel pipe placed between the first, second, and third feeding wheels towards the cutting device, eliminating the need for manual feeding of the steel pipe and saving manpower, thus making the steel pipe cutting machine more convenient to use.
[0004] However, it still has the following drawbacks: the device uses the elastic force of a spring to clamp the steel pipe with a feeding wheel for clamping and feeding, but the device does not clamp the cut steel pipe. During cutting, the steel pipe bends, which may cause the cut end of the steel pipe to be uneven, affecting the cutting quality. To address this issue, we propose a steel cutting device with a pushing structure. Utility Model Content
[0005] The purpose of this invention is to provide a steel cutting device with a pushing structure to solve the problems mentioned in the background art.

The outer surface of the second lead screw rotates through the outer surface of the mounting base via the first bearing and extends into the interior of the mounting base. The outer surface of the second lead screw extends into the interior of the slide rod and is threadedly connected to the inner wall of the slide rod. By setting the second lead screw, the slide rod, and the positioning block, rotating the second lead screw causes the positioning block to clamp the steel pipe, thereby improving the stability of steel pipe cutting.

The bevel gear is fixedly sleeved on the outer surface of the second lead screw, and the bevel gear ring is fixedly sleeved on the outer surface of the rotating shell. The thread on the outer surface of the left end of the positioning bolt passes through the right end face of the mounting base and presses against the right end face of the rotating shell. By rotating the rotating shell, positioning bolt, bevel gear, and bevel gear ring, the rotating shell is rotated, driving multiple second lead screws to rotate simultaneously, driving multiple positioning blocks to clamp and position the end of the steel pipe. During cutting, the steel pipe is positioned to prevent it from tilting and affecting the quality of the cut surface.
[0014] A further improvement is that the positioning roller is rotatably sleeved on the outer surface of the mounting shaft via a second bearing. The outer surface of the mounting shaft is fixedly connected to the inner wall of the mounting base.
