Description

Technical Field

[0001] The utility model belongs to the field of steel bar cutting, and in particular relates to a steel bar cutting device. Background Art

[0002] Rebar cutting refers to the process of accurately measuring and shearing rebar materials according to the requirements of design drawings in construction projects.

[0003] The specific operation method is as follows:

[0004] Measurement: First calculate the required length of the steel bars based on the construction drawings, and use tools such as a steel tape measure or infrared rangefinder to measure accurately.

[0005] Cutting preparation: Fix the whole bundle of steel bars and select appropriate cutting tools, such as steel bar cutting machine, grinding wheel cutting machine, manual hydraulic shears, etc.

[0006] Cutting operation: Cut the steel bars according to the measured size. Keep the cutting machine stable when using it, and do not shake it at will to ensure that the cutting surface is straight and free of burrs.

[0007] Inspection and sorting: After cutting, check again whether the length and quantity of the steel bars meet the design requirements, and classify and stack them neatly for subsequent construction use.

[0008] In the prior art, when short steel bars need to be cut, a single steel bar needs to be cut.

[0009] In order to facilitate the transportation of steel bars, they are usually bundled together. When cutting one of the steel bars in a bundle, one end of the steel bar to be cut needs to be lifted because the steel bar is in the bundle. At this time, the lifted steel bar is in an inclined state, and it is difficult to ensure that the incision is perpendicular to the steel bar during cutting, which affects the cutting quality.

[0010] Therefore, we propose a steel bar cutting device to solve the above problems. Utility Model Content

At this time, the lifted steel bar is in an inclined state, and it is difficult to ensure that the incision is perpendicular to the steel bar during cutting, which affects the cutting quality. The utility model provides a steel bar cutting device.

[0014] The driving mechanism is mounted on the mounting tube and is capable of driving the N-rod guide rods to approach each other;

[0015] The steel bar cutting mechanism includes a guide rail and a lower pressing frame, and the lower end of the guide rail is fixedly mounted on the outer side of the mounting tube;

[0016] The lower pressing frame is arranged on the guide rail and can slide up and down along the guide rail. A cutting motor is installed on the lower pressing frame, and a cutting blade is installed on the output shaft of the cutting motor.

[0017] Preferably, N groups of movable grooves are circumferentially formed on the mounting tube, and the movable grooves are arranged corresponding to the clamping blocks.

[0027] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0028] See also Figure 1-2 The utility model provides a technical solution for a steel bar cutting device:

[0029] Embodiment 1:

[0030] according to Figure 1 and Figure 2 As shown, it includes a mounting tube 1, a steel bar cutting mechanism, a driving mechanism and N groups of steel bar positioning units. The interior of the mounting tube 1 is hollow, and its two ends are open. One end of the mounting tube 1 is surrounded by N groups of guide holes. The number of the guide holes is at least two. In this embodiment, the number of the guide holes is four.

[0031] In this embodiment, there are four groups of steel bar positioning units, which correspond to four groups of guide holes respectively. The steel bar positioning units include a guide rod 41 and a clamping block 42 arranged in the inner cavity of the mounting tube 1. The guide rod 41 is slidably arranged in the guide hole, and its inner end is fixedly connected to the clamping block 42. Under the limiting action of the guide rod 41, the clamping block 42 can move vertically.

[0032] Four groups of movable grooves are arranged around the mounting tube 1, and the movable grooves are arranged corresponding to the clamping blocks 42. The driving mechanism includes four levers 3, and the levers 3 are hingedly installed in the movable grooves through pin shafts so that the levers 3 can rotate in the movable grooves. The lower ends of the levers 3 are in contact with the clamping blocks 42. The external threads arranged on the outer surface of the mounting tube 1 are threadedly connected with the internal threaded tube 2, and one end of the internal threaded tube 2 is in contact with the upper ends of the four levers 3. By rotating the internal threaded tube 2 forward, the internal threaded tube 2 drives the levers 3 to rotate during the rotation and movement process, so that the multiple clamping blocks 42 are close to each other to clamp the steel bars.

[0033] The steel bar cutting mechanism comprises a guide rail 51 and a lower pressing frame 52 . The lower end of the guide rail 51 is fixedly mounted on the outer side surface of the mounting pipe 1 .

[0034] The lower pressure frame 52 is arranged on the guide rail 51 and can slide up and down along the guide rail 51. A cutting motor 53 is installed on the lower pressure frame 52, and a cutting blade 54 is installed on the output shaft of the cutting motor 53. By driving the lower pressure frame 52 and the cutting motor 53 to move downward, the cutting blade 54 cuts the steel bar during the rotation process. Since the steel bar and the mounting pipe 1 are concentric, the cutting blade 54 can ensure verticality with the steel bar during cutting, thereby playing the role of smoothing the incision.

[0035] During specific use, the utility model is a steel bar cutting device. First, one end of the steel bar to be cut is lifted, and then the mounting tube 1 is put on the steel bar to be cut and moved to the cutting position. By rotating the internal threaded tube 2 in the forward direction, the internal threaded tube 2 drives the lever 3 to rotate during the rotation and movement, so that multiple clamping blocks 42 are close to each other to clamp the steel bar, and then the cutting motor 53 is started. The cutting motor 53 drives the cutting blade 54 to rotate, and drives the lower pressure frame 52 and the cutting motor 53 to move downward. The cutting blade 54 cuts the steel bar during the rotation process. Finally, after the steel bar is cut, the internal threaded tube 2 is rotated in the reverse direction to remove the device from the steel bar.

[0036] Embodiment 2:

[0037] On the basis of the first embodiment, Figure 1 and Figure 2 As shown, a spring 55 is sleeved on the guide rail 51, and the two ends of the spring 55 are respectively connected to the lower pressure frame 52 and the mounting pipe 1. After the cutting blade 54 completes cutting of the steel bar, the cutting motor 53 moves upward and resets by relying on the elastic force of the spring 55.

[0038] Embodiment three:

[0039] On the basis of the first embodiment, Figure 2 As shown, the mounting tube 1 is an iron pipe fitting, and a mounting hole is provided on one side of the clamping block 42 close to the inner wall of the mounting tube 1, and a magnet 43 is installed in the mounting hole. When the lower end of the lever 3 no longer squeezes the clamping block 42, the clamping block 42 is automatically adsorbed on the inner wall of the mounting tube 1 under the adsorption effect of the magnet 43.
