Abstract
Description
Technical Field
[0001] This utility model relates to the field of rebar cutting devices, specifically a rebar cutting device for construction engineering. Background Technology
[0002] The required length of steel bars varies in different parts of a building structure. For example, the length of steel bars in beams, columns, slabs and other components needs to be precisely determined according to the design drawings. By cutting the steel bars, they can be adapted to the specific component dimensions to ensure the accuracy and stability of the structure.
[0003] In existing technologies, due to the high hardness of steel bars, they are generally cut by shearing. The shearing force generated by compression is used to cut the steel bars. However, when using handheld shearing devices, since the overall length of the steel bars is relatively long, when only a short length needs to be cut, the worker needs to manually hold the steel bar in place, which is inconvenient.

[0014] 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.
[0015] Please see Figures 1-3In this embodiment of the present invention, a steel bar cutting device for construction engineering includes a hydraulic push cylinder 1. A movable shear head 4 is fixedly installed at the output end of the piston rod of the hydraulic push cylinder 1. A connecting plate 5 is bolted to the front end plate of the sleeve of the hydraulic push cylinder 1. A circular hole for the piston rod to move is opened at the center of the connecting plate 5. A hollow sleeve 6 protruding outward is welded to one end of the connecting plate 5 around the circular hole. The hollow sleeve 6 has a hollow structure. A connecting seat 8 is installed on the outer periphery of the hollow sleeve 6 through a connecting mechanism. A limit mechanism is installed on one side of the top of the bottom plate of the connecting seat 8. A steel bar groove 9 is opened on the side vertical plate of the connecting seat 8. The top of the steel bar groove 9 has an open structure. A static shear head 10 is installed on the end vertical plate of the connecting seat 8. A pressing handle 3 is installed on the top of the outer shell of the hydraulic push cylinder 1. A stabilizing seat 2 is fixedly installed on the outer wall of the outer shell of the hydraulic push cylinder 1.
[0016] In this embodiment: First, the stable seat 2 of the device is placed on the working platform. Then, the steel bar to be cut is inserted into the steel bar groove 9. At this time, the steel bar groove 9 limits the bottom end of the steel bar. Then, the limiting mechanism is adjusted to limit the top end of the steel bar. Since the lowest point and the highest point are limited and the limiting points are in a misaligned state, the steel bar is in a relatively stable state and the workers do not need to work hard to maintain the stability of the steel bar. Then, by activating the hydraulic push cylinder 1, the piston rod of the hydraulic push cylinder 1 drives the moving shear head 4 to move axially. At this time, the moving shear head 4 squeezes the steel bar. The squeezing force acts on the steel bar and, together with the static shear head 10, forms a shearing force, which can cut the steel bar. This achieves accurate cutting of the steel bar, reduces the generation of waste material, makes full use of the steel bar material, and improves the material utilization rate.
[0017] Please refer to this carefully. Figure 1 and Figure 2 The connecting mechanism includes a fixed flange 7 welded to the outer periphery of the hollow sleeve 6, and the fixed flange 7 is fixedly connected to the flange connection part of the connecting seat 8 by bolts.
[0018] In this embodiment: when installing the connecting seat 8, the flange connection part of the connecting seat 8 is connected to the fixed flange 7 using bolts and nuts, and the connecting seat 8 can be fixed.
[0019] Please refer to this carefully. Figure 2 and Figure 3 The limiting mechanism includes two sleeves 11 fixedly installed on the top of the bottom plate of the connecting seat 8. The inner wall of the sleeve 11 is slidably connected with a lifting rod 12 that extends through to the top of the sleeve 11. The top of the two lifting rods 12 is integrally formed with a limiting rod 15. The limiting mechanism also includes a screw 13 rotatably installed on the top of the bottom plate of the connecting seat 8. The top of the screw 13 is fixedly installed with a rotating handle 14. One end of the limiting rod 15 is integrally formed with an outwardly protruding connecting sleeve 16, which is threadedly connected to the screw 13.
[0020] In this embodiment: after the reinforcing bar is inserted into the reinforcing bar groove 9, the handle 14 is rotated, which drives the screw 13 to rotate. The rotating screw 13 drives the connecting sleeve 16 to move up and down. The moving connecting sleeve 16 drives the limiting rod 15 to move up and down. The limiting rod 15 drives the lifting rod 12 to slide up and down on the inner wall of the sleeve 11. After the adjustment is completed, the limiting rod 15 limits the upper part of the outer wall of the reinforcing bar. The limited reinforcing bar is in a relatively straight state. At this time, the reinforcing bar is located between the moving shear head 4 and the stationary shear head 10.
[0021] Please refer to this carefully. Figure 2 and Figure 3 The bottom end of the lifting rod 12 is integrally formed with a slider. The non-open part of the inner cavity of the sleeve 11 is used for the slider to slide up and down. The open end of the inner cavity of the sleeve 11 matches the outer wall of the lifting rod 12.
[0022] In this embodiment, the cross-sectional area of the slider is larger than that of the lifting rod 12, which can prevent the lifting rod 12 from detaching from the sleeve 11. The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the protection scope of this utility model.
