Description

Technical Field

[0001] This utility model relates to the field of engineering construction, specifically a steel bar cutting device for engineering construction. Background Technology

[0002] Engineering construction refers to the process of transforming design intentions into physical projects by organizing resources such as manpower, materials, and machinery, based on design drawings, technical specifications, and contract requirements. It includes multiple stages such as civil engineering, installation, and decoration, and involves collaborative work from multiple professional fields. Reinforcing steel is the main material in engineering construction. It forms the skeleton of concrete structures, enhancing the strength and performance of the materials. Due to the limited geometric dimensions of structural components, standard-length reinforcing steel must be cut to precise lengths according to drawings to meet anchorage, lap splicing, and structural requirements.

[0003] Traditional devices are mostly handheld cutting machines or simple stands, lacking effective clamping and length-fixing mechanisms. The reinforcing bars are prone to shifting and lifting, and the cut surface is skewed. Manual measurement is inefficient and has large errors. Therefore, a reinforcing bar cutting device for engineering construction is proposed to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a steel bar cutting device for engineering construction, which has the advantages of stable clamping, accurate length setting, fast repeatability, and no electrical control. It solves the problems of traditional devices, which are mostly handheld cutting machines or simple stands, lacking effective clamping and length setting mechanisms, making the steel bars prone to deviation and lifting, resulting in skewed cutting surfaces, and low efficiency and large errors in manual measurement.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A steel bar cutting device for engineering construction includes a base, the base having a placement groove inside, a support frame fixedly connected to the top of the base, an electric push rod fixedly connected inside the support frame, a cutting machine fixedly connected to the bottom of the electric push rod, a cutting groove located below the cutting machine inside the base, a fixing frame located on the left side of the support frame fixedly connected to the top of the base, a limit device being provided inside the fixing frame, and two sliding plates fixedly connected to the top of the base by fasteners, the tops of the two sliding plates being fixedly connected to a baffle.

[0008] The beneficial effects of this utility model are:

[0009] The steel bar cutting device used in this project has the advantages of stable clamping, accurate length setting, fast repeatability, and no electrical control required.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the limiting device includes a first bolt knob that is internally threaded to the fixing frame, a limiting block that is rotatably connected to the outside of the first bolt knob, and a limiting rod that passes through and extends to the outside of the fixing frame that is fixedly connected to the outside of the limiting block.

[0012] The beneficial effect of adopting the above-mentioned further scheme is that by using a spiral feeding method to clamp the reinforcing bar laterally, the reinforcing bar is confined to the center of the fixed frame before cutting, eliminating axial movement and radial sway, and providing a stable reference for subsequent cutting.

[0013] Furthermore, the interior of the limiting block is arc-shaped, and a buffer pad is provided on the outer side of the limiting block. A threaded sleeve is threadedly connected to the outer side of the first bolt knob.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the arc-shaped inner cavity and the buffer pad work together to transform rigid clamping into flexible wrapping, which not only increases the contact area and reduces indentation, but also absorbs the vibration at the moment of cutting and protects the surface quality of the steel bar.

[0015] Furthermore, the base has two grooves inside, which are slidably connected to the two slide plates respectively, and the interior of each of the two slide plates is threaded with a second bolt knob that passes through and extends into the interior of the two grooves respectively.

[0016] The beneficial effect of adopting the above-mentioned further solution is that by using the cooperation between the slide and the second bolt knob, the baffle can be locked at any position in the longitudinal direction, realizing the rapid switching of different fixed-length cutting and ensuring repeatability positioning accuracy.

[0017] Furthermore, corrugated grooves are provided inside the two sliding grooves and on the top of the two sliding plates, and the corrugated grooves are all arranged longitudinally.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the longitudinal meshing of the corrugated grooves forms a micro-tooth lock, which resists the reverse impact force generated during cutting, prevents the slide from loosening on its own during vibration, and ensures that the fixed length accuracy does not drift.

[0019] Furthermore, the baffle has a limiting hole inside, and the top surface of the base has scale lines.

[0020] The advantages of adopting the above-mentioned further solutions are that the limiting holes provide downward support for the reinforcing bars, reducing their bending due to their own weight; the scale lines directly map the cutting length, eliminating the need for additional measuring tools and improving on-site work efficiency.

[0026] 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.

[0027] In the embodiments, by Figure 1-4 The present invention discloses a rebar cutting device for engineering construction. The present invention includes a base 1, the base 1 having a placement groove inside, a support frame 2 fixedly connected to the top of the base 1, an electric push rod 3 fixedly connected inside the support frame 2, a cutting machine 4 fixedly connected to the bottom of the electric push rod 3, a cutting groove located below the cutting machine 4 inside the base 1, a fixing frame 5 located to the left of the support frame 2 fixedly connected to the top of the base 1, a limit device 6 provided inside the fixing frame 5, and two sliding plates 7 fixedly connected to the top of the base 1 by fasteners, the tops of the two sliding plates 7 being fixedly connected to a baffle 8.

[0028] The limiting device 6 includes a first bolt knob 61 that is internally threaded to the fixing frame 5. A limiting block 62 is rotatably connected to the outside of the first bolt knob 61. A limiting rod 63 that passes through and extends to the outside of the fixing frame 5 is fixedly connected to the outside of the limiting block 62.

[0029] In this embodiment, during actual use, the first bolt knob 61 is rotated, and the first bolt knob 61 moves forward in the threaded hole of the fixing frame 5 and pushes the limiting block 62. The limiting block 62 moves along the guide of the limiting rod 63 until the arc-shaped inner cavity hugs the steel bar. After the buffer pad is compressed, it forms an elastic support. The threaded sleeve 10 then locks the first bolt knob 61 to prevent it from loosening, thus completing the clamping.

[0030] The limiting block 62 has an arc-shaped interior and a buffer pad on its outer side. The first bolt knob 61 is threadedly connected to a threaded sleeve 10 on its outer side.

[0031] In this embodiment, during actual use, the arc-shaped inner cavity of the limiting block 62 matches the outer circle of the reinforcing bar. After the buffer pad is deformed by pressure, it fills the micro gap. The threaded sleeve 10 continues to tighten the first bolt knob 61, so that the limiting block 62 maintains a constant clamping force and avoids the reinforcing bar from slipping slightly under the action of cutting force.

[0032] The base 1 has two grooves inside that are slidably connected to two slide plates 7. The interior of each slide plate 7 is threaded with a second bolt knob 9 that passes through and extends into the two grooves.

[0033] In this embodiment, during actual use, after the slide plate 7 slides along the groove to the length indicated by the scale line, the second bolt knob 9 is tightened. The front end of the second bolt knob 9 presses against the bottom surface of the groove, and the corrugated grooves interlock. The slide plate 7 and the base 1 are immediately rigidly connected, and the position of the baffle 8 is fixed, becoming the reference for the end of the reinforcing bar.

[0034] Corrugated grooves are provided inside the two slides and on the top of the two slide plates 7, and the corrugated grooves are arranged longitudinally.

[0035] In this embodiment, during actual use, the longitudinal corrugated grooves on the top surface of the slide plate 7 and the bottom surface of the slide groove interlock under the pressure of the second bolt knob 9, forming multiple transverse blocking teeth. Even if the cutting machine 4 applies a downward impact, the slide plate 7 still maintains zero displacement.

[0036] The baffle 8 has a limit hole inside, and the top surface of the base 1 has scale lines.

[0037] In this embodiment, during actual use, the front end of the reinforcing bar is inserted into the limiting hole of the baffle 8, and the end face of the reinforcing bar is in contact with the inner side of the baffle 8. The operator can directly read and record the length through the scale line on the top surface of the base 1 without secondary measurement, thus shortening the material preparation time.

[0038] Working principle:

[0039] Place the reinforcing bar in the placement groove on the top surface of the base 1, so that one end passes through the fixing frame 5 and is inserted into the limiting hole of the baffle 8. Push and pull the sliding plate 7 to the target length according to the scale line of the base 1, and then tighten the second bolt knob 9. The sliding plate 7 engages and locks with the corrugated groove of the slide. Turn the first bolt knob 61 to push the limiting block 62 to clamp the reinforcing bar. The buffer pad absorbs the excess gap. The threaded sleeve 10 locks the first bolt knob 61. Start the electric push rod 3 to drive the cutting machine 4 to move down to complete the cutting. Throughout the process, the reinforcing bar must be kept concentric with the limiting hole and parallel to the scale line. During the cutting, it is forbidden to touch the limiting block 62 and the baffle 8 to avoid damaging the positioning.
