Description

Technical Field

[0001] This utility model relates to the field of rebar cutting technology, and more specifically, to a mobile rebar cutting device. Background Technology

[0002] A rebar cutting device is a widely used rebar processing equipment in construction sites, bridge construction, tunnel construction, and rebar processing centers. It is mainly used for cutting rebar to a fixed length in civil engineering projects and is an indispensable piece of equipment in the rebar processing stage. The working principle of the rebar cutting device is mainly based on the motor driving the eccentric shaft to rotate. The eccentric surface of the eccentric shaft pushes the plunger to reciprocate, causing the plunger pump to generate high-pressure oil which is forced into the oil cylinder, pushing the piston inside the oil cylinder and driving the moving blade forward. This blade then intersects with the fixed blade fixed on the support, thus cutting the rebar.

[0003] The document CN219746179U discloses a rebar cutting device for civil engineering. In this device, a cylinder pushes a cutting blade downward to cut the rebar. However, the angle of the cutting blade is fixed and cannot be adjusted. When the operator places the rebar on a metal filter screen for cutting, the rebar always tilts, resulting in a tilted cut. The tilted rebar has a sharp cut, which can easily cause safety accidents during subsequent handling. Therefore, we propose a mobile rebar cutting device. Utility Model Content

A handle 15 is fixedly connected to the end of the connecting plate 14. A first mounting plate 16 is fixedly connected to the inner wall of the connecting plate 14. The output end of the motor 13 is rotatably connected to the first mounting plate 16. A connecting shaft 18 is rotatably connected through the inner wall of the first mounting plate 16. Synchronous pulleys 17 are fixedly connected to the outer circumference of both the output end of the motor 13 and the connecting shaft 18. The connection is made via a synchronous belt drive. A cutting wheel 21 is fixedly connected to the outer circumference of the connecting shaft 18. The motor 13 drives the connecting shaft 18 to rotate via the synchronous pulley 17, which in turn drives the cutting wheel 21 to rotate. The cutting wheel 21 can cut the steel bars. By placing the steel bars on top of the barrier net 8, the hydraulic rod 9 pushes the cutting wheel 21 downward. The operator can adjust the angle of the steel bar cutting by holding the handle 15 and rotating the mounting sleeve 11 according to the inclined section of the steel bar, so as to make the cut of the steel bar smoother and reduce the safety risks during the transportation of the steel bars.

[0025] A connecting sleeve 22 is rotatably connected to the outer circumference of the connecting shaft 18. The end of the connecting sleeve 22 is fixedly connected to the second mounting plate 20. A protective cover 23 is fitted on the outer circumference of the connecting shaft 18. The end of the connecting sleeve 22 is fixedly connected to the protective cover 23. During the cutting process, the protective cover 23 can block the metal fragments generated when the steel bar is cut, thereby protecting the operator.

[0026] The bottom of the mounting frame 1 is fixedly connected to a support plate 2, and the bottom of the mounting frame 1 is fixedly connected to an inclined support plate 3.

[0030] The motor 13 drives the connecting shaft 18 to rotate via the synchronous pulley 17, which in turn drives the cutting wheel 21 to rotate, enabling the cutting wheel 21 to cut the steel bars.

[0031] During the cutting process, the protective cover 23 can block the metal debris generated when the steel bar is cut, thereby protecting the operator;

[0032] Metal shavings generated during cutting can splash onto the blocking net 8, which can intercept the metal shavings and prevent them from flying around. Meanwhile, the metal shavings that fall onto the blocking net 8 will fall into the collection tank 4. By pulling the connecting rod 7 along the inner wall of the collection tank 4, the metal shavings inside the collection tank 4 can be discharged through the chip discharge hole 5.
