Description

Technical Field

[0001] This utility model relates to the field of rebar cutting technology, specifically a rebar cutting device for building construction with a positioning mechanism. Background Technology

[0002] Construction steel bars refer to various types of steel bars used in reinforced concrete. They are an indispensable building material in construction. Construction steel bars come in a variety of types, classified by steel type as non-alloy steel bars, low-alloy steel bars, and alloy steel bars; and by production process as hot-rolled steel bars, heat-treated steel bars, residual heat-treated steel bars, cold-rolled steel bars, cold-drawn steel bars, etc.

[0003] As disclosed in the patent announcement CN214866900U, a steel bar cutting device for building construction includes a support leg. A base plate is fixedly installed on both sides of the bottom of the support leg, and a vertical plate is fixedly installed on both sides of the top of the support leg. Through holes are opened on opposite sides of the two vertical plates. A horizontal plate is fixedly installed on the top of the two vertical plates, and a hydraulic telescopic rod is fixedly installed on one side of the bottom of the horizontal plate. The beneficial effects of this utility model are as follows: through the coordinated use of the vertical plate, slide groove, cutting disc, electric slider, mounting block, hydraulic telescopic rod, first motor, vertical rod, spring, clamping plate, fixing plate, support plate, first sliding hole, stop block, and movable plate, as the cutting disc moves downwards to cut the steel bar, the clamping force of the clamping plate on the steel bar increases, ensuring the stability of the steel bar during the cutting process.

[0004] Although the aforementioned patent uses a spring clamping mechanism to fix the reinforcing bars, in the actual cutting process, the elastic deformation of the spring may cause fluctuations in clamping force due to the impact and vibration of the cutting disc on the reinforcing bars, affecting the stability of the reinforcing bars, or even causing the reinforcing bars to bounce, affecting the cutting accuracy and potentially causing safety hazards.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] like Figure 1-4 As shown, this utility model provides a technical solution:

[0026] A rebar cutting device for building construction with a positioning mechanism includes a workbench 1, with a frame A2 fixedly connected to its top center. A cutting mechanism is provided between the frame A2 and the workbench 1. The cutting mechanism includes a hydraulic rod 6 fixedly connected to the top center of the frame A2. A horizontal lifting frame 7 is fixedly connected to the output shaft end of the hydraulic rod 6. A vertical cutting blade 8 is fixedly connected to the center of the front of the lifting frame 7. The cutting mechanism also includes a cutting platform 9 fixedly connected to the upper surface of the middle center of the workbench 1, and an L-shaped bracket 10 fixedly connected to the center of the back of the lifting frame 7. A clamp 11 is fixedly connected to the bottom end of the L-shaped bracket 10. V-grooves 12 are provided on the opposite side of the clamp 11 and the cutting platform 9. A frame B5 is fixedly connected to the workbench 15. The frame B5 is connected to the middle of the top right side of the workbench 1. The frame B5 is equipped with a positioning mechanism, which includes two clamping rollers 18. The clamping rollers 18 are movably installed at the top and bottom of the frame B5. Guide grooves 19 are opened on both sides of the frame B5. A vertical guide rod 20 is fixedly connected inside the left guide groove 19. A vertical double-acting screw 21 is rotatably connected inside the right guide groove 19 through a bearing. A motor B22 is fixedly installed at the top right side of the frame B5. The output shaft of the motor B22 is coaxially connected to the double-acting screw 21. Movable blocks 23 are movably connected to both ends of the clamping rollers 18 through a rotating shaft. The left movable block 23 is movably sleeved with the guide rod 20. The right movable block 23 is threadedly connected to the double-acting screw 21.

[0027] In this embodiment, a double clamping mechanism is formed by setting up a positioning mechanism of upper and lower clamping rods 18 in conjunction with a bidirectional lead screw 21, and a clamping structure of V-groove 12 driven by L-shaped bracket 10. This effectively overcomes the defect of unstable clamping force of traditional spring clamping mechanism under cutting vibration, and significantly improves the positioning accuracy and stability of steel bars during the cutting process.

[0028] like Figure 2 As shown, a placement trough 3 is located at the top center of the left side of the workbench 1. A collection box 4 is movably installed inside the placement trough 3. A vibration mechanism is provided in the middle of the placement trough 3. The vibration mechanism includes a movable trough 13 located in the middle of the placement trough 3. An eccentric wheel 14 is rotatably connected to the placement trough 3 through a bearing. A motor A15 is fixedly installed inside the right side of the movable trough 13. The output shaft of the motor A15 is coaxially connected to the eccentric wheel 14. Electric push rods 16 are fixedly connected to both ends of the left side of the workbench 1. Positioning holes 17 are provided at both ends of the left side of the collection box 4.

[0029] In this embodiment, the electric push rod 16 and the positioning hole 17 are used to fix the collection box 4, and the eccentric wheel 14 vibration mechanism is set up to realize the automatic collection and orderly arrangement of the steel bars after cutting. This solves the problem of chaotic steel bar accumulation in traditional equipment and improves the safety of operation and collection efficiency.

[0030] Working principle: After the rebar enters the frame B5 from the right, the motor B22 starts and drives the bidirectional lead screw 21 to rotate, so that the upper and lower clamping rollers 18 move synchronously towards each other along the guide rod 20 and the bidirectional lead screw 21 through the movable block 23, clamping and positioning the rebar; then the hydraulic rod 6 pushes the lifting frame 7 to move down, driving the cutting blade 8 to cut the rebar located on the cutting table 9. At the same time, the L-shaped bracket 10 drives the clamping seat 11 to press down, forming a double clamping through the V-shaped groove 12 and the cutting table 9; the cut rebar segments fall into the collection box 4 in the left placement groove 3. At this time, the electric push rod 16 extends and inserts into the positioning hole 17 of the collection box 4 to fix it. At the same time, the motor A15 drives the eccentric wheel 14 to vibrate and make the rebar evenly distributed.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
