Description

Technical Field

[0001] This utility model belongs to the field of cutting equipment technology, specifically relating to a steel bar cutting device for construction engineering. Background Art

[0002] Reinforcing bars refer to steel used in reinforced concrete and prestressed reinforced concrete. Their cross-section is circular, and sometimes square with rounded corners. They include plain round bars, ribbed bars, and twisted bars. Some reinforcing bars need to be cut with a cutting device before use.

[0003] Chinese patent application number 202120369261.6 discloses a rebar cutting device for construction engineering, including a base. A support plate is fixedly connected to the upper surface of the base. A toothed plate is connected to the left side of the support plate through an upper connecting plate and a lower connecting plate. A drive motor is fixedly installed on the left side of the support plate through a sliding groove and a slider. Two fixing plates are fixedly connected to the upper surface of the base. Each of the two fixing plates has two first through holes. A groove is formed inside the fixing plate. A rotating rod is inserted through a bearing on the outer surface of the groove. Multiple telescopic rods are fixedly connected to the inner wall of the first through holes. An arc-shaped extrusion plate is fixedly connected to the end of the telescopic rod away from the first through hole. Through a series of structural settings, this device has the advantages of good rebar fixing effect, preventing the rebar from slipping easily during the cutting process, automatic cutting, and high cutting efficiency.

[0004] Although the aforementioned patent enables the cutting of steel bars in construction projects, its steel bar fixing device has a relatively poor fixing effect on the steel bars and is not very convenient to adjust; the lifting structure of its cutting sand disc is raised and lowered by adjusting the gear plate, which has poor overall stability and relatively high manufacturing cost.

The clamping seat 38 is mounted on the lower end of the T-shaped sliders 37. The transmission assembly 35 is located on the outer side of the mounting frame 2 on the surface of the double-acting lead screw 36.

[0023] By adopting the above technical solution, the reinforcing bar is passed through the interior of mounting bracket 1 2 and mounting bracket 2 4. The motor 1 32 is turned on. The motor 1 32 drives the drive gear 34 to rotate through the output end. The drive gear 34 rotates and drives the driven gear 33 to rotate.

[0034] In this embodiment, when in use, motor 3 910 is turned on, and motor 3 910 drives the rotating shaft 908 to rotate through its output end. The rotating shaft 908 drives the cutting disc 909 to rotate. Then, motor 2 903 is turned on, and motor 2 903 drives the threaded rod 904 to rotate through its output end. The rotation of the threaded rod 904 drives the nut block 905 to move downward. The downward movement of the nut block 905 drives the connecting rod 906 to move downward. The downward movement of the connecting rod 906 drives the U-shaped plate 907 to move downward, thereby driving the cutting disc 909 to cut the steel bar. The sliding of the nut block 905 drives the T-shaped slider 2 901 to slide inside the T-shaped groove 902, thereby improving the stability of the sliding process of the nut block 905.

The bidirectional lead screw 1 (36) rotates, causing two sets of T-shaped sliders 1 (37) to move closer together. The two sets of T-shaped sliders 1 (37) slide, causing the clamping seat 38 to fix the reinforcing bar. The T-shaped sliders 1 (37) slide inside the sliding groove 31, thereby improving the stability of the clamping seat 38 during sliding. The bidirectional lead screw 1 (36) rotates, driving pulley 1 (351) to rotate. The pulley 1 (351) rotates, driving the transmission belt 352 to rotate. The transmission belt 352 rotates, driving pulley 2 (354) to rotate.
