Description

Technical Field

[0001] This utility model relates to the field of steel bar cutting technology in construction, and in particular to a steel bar cutting device for construction. Background Technology

[0002] In the field of building construction, steel bars are core load-bearing components, and their processing precision directly affects the stability and safety of building structures.

[0003] Rebar cutting is a crucial step in the rebar processing procedure. Rebar cutting equipment is used to cut rebar into specific lengths and specifications according to construction requirements.

[0004] While existing rebar cutting devices can cut rebar, most have fixed feeding structures, making it difficult to flexibly adapt to rebars of different diameters. This can easily lead to feeding deviations and subsequent dimensional errors in the cut. Furthermore, the cutting process often employs a unidirectional cutting method, which can cause uneven stress on the rebar, resulting in cross-sectional tilting and failing to meet high-precision construction requirements. Some devices also lack effective protective structures, allowing debris to fly during cutting and pose safety hazards to operators. Accumulated debris can also pollute the working environment. In terms of clamping and rotation, traditional devices have poor clamping mechanism adjustability, making it difficult to stably clamp rebars of different diameters. The lack of rotation functionality also hinders multi-angle cutting, resulting in low processing efficiency. Therefore, a rebar cutting device for construction is proposed to address these problems.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3This utility model provides an embodiment of a steel bar cutting device for building construction, including a frame 1. A feeding assembly 2 is provided on one side of the upper surface of the frame 1 to achieve stable feeding of steel bars and ensure that the steel bars maintain a straight feed during processing. The feeding assembly 2 includes a mounting frame 21, the bottom end of which is fixedly connected to the top of the frame 1, so that the feeding assembly 2 and the frame 1 form a stable connection and ensure the stability of the overall structure. A bidirectional threaded rod 22 is rotatably connected to the inner side of the mounting frame 21. The rotation of the bidirectional threaded rod 22 can simultaneously drive two adjusting slides 24 to move in opposite directions. An adjusting handwheel 23 is fixedly connected to the top of the bidirectional threaded rod 22 through the upper surface of the mounting frame 21, which is convenient for the operator to manually rotate the bidirectional threaded rod. The threaded rod 22 adjusts the spacing of the feeding guide rollers 25. Two adjusting slides 24 are threadedly connected to the outer side of the threaded rod 22, respectively engaging with the positive and negative thread sections of the threaded rod 22 for simultaneous spacing adjustment. The two adjusting slides 24 are mirror-image positioned along the central axis of the rotating slot 32, ensuring uniform clamping and conveying force on the reinforcing bars and preventing bar misalignment. The two sides of the adjusting slides 24 are slidably connected to the inner wall of the mounting frame 21, restricting their movement direction and ensuring they can only slide up and down along the inner wall of the mounting frame 21, guaranteeing adjustment accuracy. Feeding guide rollers 25 are fixedly connected to the outer surfaces of the two adjusting slides 24, and the rotation of the feeding guide rollers 25 facilitates the conveying of the reinforcing bars, reducing... To minimize friction between the steel bars and the equipment, a cutting assembly 4 is installed on the other side of the upper surface of the frame 1 for precise cutting of the steel bars. The cutting assembly 4 includes a protective box 41, the bottom of which is fixedly connected to the upper surface of the frame 1 for safety protection, preventing debris from flying and injuring people during the cutting process. An observation window 42 is fixedly connected to the outer surface of the protective box 41, allowing operators to observe the internal cutting process and keep track of the progress. A laser meter 43 is fixedly connected to the top of the inner wall of the protective box 41 to accurately measure the feed length of the steel bars and ensure the accuracy of the cutting dimensions. A limiting slide 44 is fixedly connected to the inner wall of the protective box 41 to provide guidance and support for the movement of the adjusting slide 45. The inner side of the limiting slide 44 is slidably connected to... An adjustable slide 45 is provided, which can slide up and down along the limiting slide 44 to drive the electric cutting tool 47 to adjust the cutting position. An electric lifting rod 46 is fixedly connected to the top of the protective box 41 to provide power for the lifting and lowering of the adjustable slide 45. The telescopic end of the electric lifting rod 46 is fixedly connected to the upper surface of the adjustable slide 45. The telescopic movement of the electric lifting rod 46 drives the adjustable slide 45 and the electric cutting tool 47 to move up and down to realize the cutting action. The electric cutting tool 47 is fixedly connected to the inner surface of the adjustable slide 45 as the execution component of the cutting operation. It can rotate at high speed to cut the steel bars. A chip discharge guide groove 5 is provided on the side of the top of the frame 1 near the cutting component 4 to collect and discharge the chips generated during the cutting process and keep the equipment and working environment clean.

[0020] Reference Figure 1 , Figure 2 and Figure 4 A rotating assembly 3 is located on the upper surface of the frame 1 between the feeding assembly 2 and the cutting assembly 4. This assembly rotates the reinforcing bar, allowing for bidirectional rotational cutting by the electric cutting blade 47, eliminating the problem of tilted cross-sections caused by unidirectional cutting. The rotating assembly 3 includes a fixed base 31, the bottom of which is fixedly connected to the top of the frame 1, providing a stable mounting foundation. A support base 33 is fixedly connected to the outer wall of the fixed base 31 for mounting and fixing the drive motor 34. The top of the support base 33 is fixedly connected to the drive motor 34, providing support for the rotation of the rotating ring frame 36. The drive motor 34 provides power, and its output end is fixedly connected to the drive gear 35. The drive motor 34 drives the drive gear 35 to rotate. The upper surface of the fixed base 31 has a mounting groove that extends through the interior of the rotating slot 32. The inner wall size of the mounting groove is larger than the outer diameter of the drive gear 35, providing mounting space for the drive gear 35 and preventing interference between the drive gear 35 and the fixed base 31 when rotating. The inner wall of the fixed base 31 has a rotating slot 32, which provides guidance and limit for the rotation of the rotating ring frame 36. The rotating ring frame 36 is movably connected to the inner side of the rotating slot 32. 6. It can rotate freely within the rotating slot 32, driving the mounting base 38 and the electric telescopic clamp 39 to rotate synchronously. The outer side of the rotating ring frame 36 is provided with a driven tooth groove 37, and the driving gear 35 is meshed with the driven tooth groove 37. Through the meshing transmission of the driving gear 35 and the driven tooth groove 37, the power of the drive motor 34 is transmitted to the rotating ring frame 36, realizing the rotation of the rotating ring frame 36. The inner side of the rotating ring frame 36 is fixedly connected to the mounting base 38 for mounting and fixing the electric telescopic clamp 39. The inner side of the mounting base 38 is fixedly connected to the electric telescopic clamp 39 for clamping. The system holds and fixes the reinforcing bars to ensure they do not loosen or shift during rotation and processing. Four mounting bases 38 and four electric telescopic clamps 39 are provided, allowing for simultaneous clamping of multiple reinforcing bars for processing, thus improving work efficiency. The four mounting bases 38 are evenly distributed in a ring along the inner wall of the rotating ring frame 36, ensuring uniform force distribution on each electric telescopic clamp 39 and facilitating the loading, unloading, and positioning of the reinforcing bars. Furthermore, the four mounting bases 38 and electric telescopic clamps 39 are arranged in a one-to-one correspondence, ensuring that the electric telescopic clamp 39 on each mounting base 38 can work independently, achieving precise clamping of reinforcing bars of different diameters.

[0021] Working principle: During use, the operator rotates the adjusting handwheel 23 to drive the bidirectional threaded rod 22 to rotate according to the diameter of the rebar. This causes the two adjusting slides 24 to slide along the inner wall of the mounting frame 21 and adjust the spacing until the feeding guide roller 25 is in contact with the surface of the rebar. One end of the rebar to be cut is passed through the feeding assembly 2 and conveyed to the rotating assembly 3 by the feeding guide roller 25. The rebar continues to be fed into the cutting assembly 4. The laser meter 43 measures the feed length in real time. Feeding stops when the preset cutting size is reached. At this time, the four electric telescopic clamps 39 move synchronously to clamp and fix the rebar. The electric cutting blade 47 in the protective box 41 starts to rotate at high speed, and at the same time, the electric lifting rod 46... The adjusting slide 45 is pushed down along the limiting slide 44 to realize the cutting action. During the cutting process, the drive motor 34 drives the rotating ring frame 36 to rotate in the rotating slot 32 of the fixed seat 31 through the meshing of the drive gear 35 and the driven gear groove 37. This causes the steel bar held by the electric telescopic clamp 39 to rotate synchronously, forming a bidirectional rotational cutting with the electric cutting tool 47, effectively avoiding the tilting of the cross-section. The chips generated by cutting are collected and discharged through the chip guide 5. The operator can monitor the cutting situation through the observation window 42. After the single steel bar is cut, the electric telescopic clamp 39 is released, and the feeding assembly 2 continues to feed the steel bar for the next cutting, realizing batch operation.
