Description

Technical Field

[0001] This utility model relates to the field of steel bar processing technology, and more specifically, to a cutting device for steel bar processing. Background Technology

[0002] Steel bars are a key type of steel used in reinforced concrete and prestressed reinforced concrete structures. They possess high strength, ductility, and good mechanical properties, and are widely used in construction, bridges, roads, and other engineering projects. Their main function is to enhance the tensile strength, seismic resistance, and load-bearing capacity of concrete. Due to their high strength, ductility, and durability, steel bars have become an indispensable material in modern construction and engineering. Their diverse types and wide range of applications enable them to play an important role in improving structural performance and ensuring building safety. During the processing of steel bars, cutting equipment is often used to cut them into the required lengths.

[0003] For example, Chinese Patent Publication No. CN201821065448.1 discloses a rebar cutting device, which includes a base, a drive motor, a cutter shaft, and a shearing blade. The base is also equipped with an anti-deviation fixing device, which includes a housing and a high-pressure gas tank fixed above the housing. The housing has a horizontal guide cavity, and a piston is slidably connected to the guide cavity. The piston has a return spring and a sliding fixing plate at both ends, and the right end of the return spring is fixedly connected to the piston. This device, by setting the anti-deviation fixing device, can effectively fix the rebar during cutting. The operation is simple and quick, preventing the rebar from coming out of the fixing groove under force, reducing the rolling of the rebar, improving the cutting efficiency, and avoiding the safety hazards caused by the rebar popping out under force after cutting. Unlike conventional clamp-type fixing, it can greatly improve processing efficiency.

[0004] However, in the above-mentioned technical solutions, traditional steel bar cutting equipment usually uses hydraulic shearing or high-speed sawing to complete the cutting operation. However, due to the high hardness and high plasticity of steel bars, metal burrs and residual debris are easily generated at the cut during the cutting process. These burrs and debris not only affect the flatness of the steel bar cut, but also increase the risk of workers being scratched or cut during subsequent handling, binding or welding. Especially in batch processing scenarios, manual secondary grinding is both time-consuming and increases labor intensity. Utility Model Content

[0005] The main purpose of this utility model is to provide a cutting device for steel bar processing, which can effectively solve the problem that traditional steel bar cutting devices in the background technology usually use hydraulic shearing or high-speed sawing to complete the cutting operation. However, due to the high hardness and high plasticity of steel bars, metal burrs and residual debris are easily generated at the cut end during the cutting process. These burrs and debris not only affect the flatness of the steel bar cut end, but also increase the risk of workers being scratched or cut during subsequent handling, binding or welding. Especially in batch processing scenarios, manual secondary grinding is both time-consuming and increases labor intensity.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a cutting device for steel bar processing, comprising a base, a first groove provided on the base, a first hydraulic rod and two placement platforms provided in the first groove, a tool holder provided on the first hydraulic rod, a cutting blade provided on the tool holder, second grooves provided on both sides of the cutting blade, an adjustment component and a connecting block respectively provided on both sides of the tool holder, a motor fixedly mounted on the connecting block, a first rotating roller provided on the motor, a grinding belt provided on the first rotating roller, a first baffle provided on the side of the connecting block near the placement platform, and the first baffle and the connecting block being fixedly connected by bolts.

[0007] Preferably, there is a certain gap between the two placement platforms, the cutter is located between the adjustment component and the connecting block, the first rotating roller is rotatably connected to the connecting block, and the polishing belt passes through the second groove.

[0008] Preferably, the adjustment component includes a component base, on which a second hydraulic rod is fixedly mounted, and a push block is fixedly disposed on the second hydraulic rod. A T-shaped groove is provided on one side of the push block, and a T-shaped slider is slidably disposed in the T-shaped groove.

[0009] Preferably, a second rotating roller is rotatably mounted on the component base, and a second baffle is provided on the side of the push block away from the T-shaped groove.

[0010] Preferably, the component base and the T-shaped slider are fixedly mounted on the tool holder.

[0011] Preferably, the second rotating roller is connected to the first rotating roller by a grinding belt, and the second baffle is fixedly connected to the push block by bolts.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) When using this utility model, the steel bar is first placed on the placement platform, and then the first rotating roller is rotated by the motor. The first rotating roller drives the grinding belt, and then the first hydraulic rod moves the tool holder downward. The tool holder drives the cutter to move and cut the steel bar. After cutting, the tool holder continues to move downward and the grinding belt is used to grind the cut end of the steel bar to remove the metal burrs and residual metal debris generated during cutting, reduce the probability of work-related injuries during handling and binding, eliminate the step of manual grinding, shorten the process flow, and improve the production efficiency when cutting in batches.

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

[0019] like Figure 1 and Figure 2As shown, a rebar cutting device includes a base 1, on which a first groove 2 is provided.

[0021] A second rotating roller 806 is rotatably mounted on the component base 801, and a second baffle 807 is provided on the side of the push block 803 away from the T-shaped slide groove 804.

[0022] When it is necessary to tension the grinding belt 12, the push block 803 is moved away from the connecting block 9 by the second hydraulic rod 802, and the second rotating roller 806 moves with the push block 803, thereby tensioning the grinding belt 12.

[0023] The working principle of this steel bar cutting device:

[0024] In use, the steel bar is first placed on the placement platform 4. Then, the first rotating roller 11 is rotated by the motor 10. The first rotating roller 11 drives the grinding belt 12.

This reduces the probability of work-related injuries during handling and binding, eliminates the need for manual grinding, shortens the process flow, and improves production efficiency when cutting in batches.
