Description

Technical Field

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

[0002] Construction refers to the production activities during the implementation phase of an engineering project. It encompasses the construction process of various buildings and structures, covering a series of operational steps from the completion of the project's planning and design to the final delivery of the completed building. In the construction process, steel bars are an essential component, and steel bar cutting devices are required to ensure the required length of the steel bars.

[0003] The existing technology has the following drawbacks: When cutting steel bars at angles, the method of manually rotating the steel bars and relying on hand pressure for positioning is often used. However, this manual operation method has many disadvantages. On the one hand, it is difficult to accurately control the cutting angle by simply rotating the steel bars by hand, and the operation is not flexible enough, making it difficult to accurately adjust the steel bars to the required specific angle. On the other hand, relying on hand pressure to position the steel bars has poor stability, and the steel bars are prone to displacement during the cutting process, resulting in deviations in the cutting angle. Once the cutting angle is inaccurate, it will have an adverse effect on the quality of subsequent construction. Therefore, a steel bar cutting device for building construction with good cutting effect is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a steel bar cutting device for building construction with good cutting effect, which aims to improve the problem that deviations are easy to occur when manually pressing the steel bar and controlling its specific angle in the prior art.

[0030] 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.

[0031] Reference Figures 1-3This utility model provides an embodiment of a steel bar cutting device for construction with good cutting effect, including a cutting table 1. A support frame 2 is fixedly connected to the top of the cutting table 1. The support frame 2 mainly supports and connects the cutting blade 3. The cutting blade 3 is provided on the support frame 2. A hydraulic rod is provided at the cutting blade 3. The cutting blade 3 can be driven by the hydraulic rod to complete the cutting process. This is the existing conventional technology and will not be described in detail. The top of the cutting table 1 contacts a fixed platform 4. A fixed frame 5 is fixedly connected to the outer wall of the fixed platform 4. The fixed frame 5 mainly supports and connects the entire positioning plate 6. The positioning plate 6 is provided in the middle of the fixed frame 5. An electric telescopic rod is provided on the positioning plate 6 to move the positioning plate 6 vertically. The positioning plate 6 is used to fix the steel bar. A round tube 7 is fixedly connected to the bottom of the fixed platform 4. A limit mechanism is provided on the inner wall of the round tube 7. A slot 11 is opened on the inner wall of the cutting table 1. A positioning component is provided on the side wall of the cutting table 1.

[0032] The limiting mechanism includes a pressing block 8, which is slidably connected to the inner wall of the round tube 7. The end of the pressing block 8 is fixedly connected to an insert block 9, which is protruding. The protrusion can cooperate with the slot 11 to limit the entire fixed platform 4. The outer wall of the insert block 9 is elastically connected to the round tube 7 through a return spring 10.

[0033] Reference Figures 3-4 The positioning assembly includes a motor 13, which is fixedly connected to the side wall of the cutting table 1. The motor 13 can rotate in both directions to control the rotation direction of the threaded rod 14. This is a conventional mechanical technique and will not be described in detail here. The output end of the motor 13 passes through the cutting table 1 and is fixedly connected to the threaded rod 14. A slider 15 is provided on the outer wall of the threaded rod 14. The inner wall of the slider 15 has a pattern that matches the threaded rod 14, which allows the slider 15 to move laterally along the outer wall of the threaded rod 14. A positioning ring 16 is fixedly connected to the top of the slider 15. The extension angle of the arc surface of the positioning ring 16 is designed according to the rotation point of the circular tube 7. This allows the reinforcing bar to move closely against the inner wall of the positioning ring 16 during rotation and continuously position it. The positioning ring 16 has a central hole, allowing the reinforcing bar to contact the inner wall of the positioning ring 16 to position its cutting length. A pointer 17 is fixedly connected to the outer wall of the positioning ring 16, which allows the operator to easily observe the position of the pointer 17 on the scale line 12. The top of the cutting table 1 is provided with the scale line 12. The threaded rod 14 is rotatably connected to the inner wall of the cutting table 1. The cutting table 1 has a slot to accommodate the rotation of the threaded rod 14 and the sliding of the slider 15. The slider 15 is slidably connected to the inner wall of the cutting table 1.

[0034] Reference Figures 1-3The outer wall of the insert 9 is fixedly connected to one end of the return spring 10. When the insert 9 moves forward, it will compress the return spring 10. When resetting, the elastic force of the return spring 10 will carry the insert 9 back to its original position. The other end of the return spring 10 is fixedly connected to the inner wall of the front end of the round tube 7. The insert 9 passes through and is slidably connected to the inner wall of the round tube 7. The round tube 7 is provided with corresponding slots for the pressing block 8 and the insert 9, which can satisfy the pressing block 8 and the insert 9 to slide along the slots. The insert 9 is inserted into the inner wall of the slot 11. The pressing block 8 passes through and is slidably connected to the inner wall of the fixed platform 4. The round tube 7 is rotatably connected to the inner wall of the cutting platform 1. The middle part of the fixed platform 4 has a V-shaped opening. The surface of the V-shaped opening is made of rubber material. The rubber material can increase the friction with the steel bar and prevent the steel bar from moving during the cutting process.

[0035] Working principle: Firstly, when positioning and fixing the reinforcing bar, the motor 13 can be started to rotate the threaded rod 14 in both directions, causing the slider 15 to move left and right on the cutting table 1. The pointer 17 and the scale line 12 are used to observe the position of the positioning ring 16, determining the length between the cutting point of the reinforcing bar and the positioning ring 16. When fixing the reinforcing bar, simply place it horizontally at the V-shaped opening of the fixing table 4, with the right end of the reinforcing bar as shown... Figure 1 As shown, the positioning plate 6 is pressed against the opening of the positioning ring 16, and then the electric telescopic rod is activated to move the positioning plate 6 downwards to fix the steel bar.

[0036] When the cutting angle of the rebar needs to be adjusted, simply press the pressing block 8 to move the insert block 9 and compress the return spring 10, so that the insert block 9 and the slot of the slot 11 are separated. At this time, the fixed platform 4 can change the cutting angle of the rebar. When the limit is needed, release the pressing block 8 by hand and use the reverse elastic force of the return spring 10 to move the pressing block 8 and the insert block 9 back to the starting position, so that the insert block 9 is inserted into the slot of the slot 11. During the rotation, the rebar will stick to the inner wall of the positioning ring 16, and the rebar can still be positioned when the angle changes.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
