Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0022] An embodiment provided by the present invention is as follows: As Figure 1 shown, a steel bar cutting device for building construction, as Figure 1 shown, includes a machine tool 1, a cutting plane 2, a cutting mechanism 3, a hydraulic device 4, and a steel bar positioning assembly 5.

[0023] As Figure 1 shown, a cutting plane 2 is provided at the center of the machine tool 1, and a groove with a downward arc is provided on the surface of the cutting plane 2. A cutting mechanism 3 is fixed above the cutting plane 2. The multiple steel bars on the cutting plane 2 are toggled and respectively positioned in the groove, saving the operation of manual placement. The placement position is accurate, and the placement angle is completely perpendicular to the cutting direction, improving the efficiency of steel bar cutting.

[0024] As Figure 1 shown, the steel bar positioning assembly 5 is slidably connected to the machine tool 1, and two groups of steel bar positioning assemblies 5 are provided, respectively located on both sides of the cutting mechanism 3. The functions of the two groups of steel bar positioning assemblies 5 are different. First, the two groups of steel bar positioning assemblies 5 behind the cutting mechanism 3 are moved to positions corresponding to the length of the steel bar to be cut from the cutting blade 3322 to limit the head of the steel bar; the two groups of steel bar positioning assemblies 5 in front of the cutting mechanism 3 are used to push the steel bars placed on the cutting plane 2 forward to the positions of the two groups of steel bar positioning assemblies 5 behind the cutting mechanism 3. The heads of all the steel bars abut against the two groups of steel bar positioning assemblies 5 behind the cutting mechanism 3. At this time, the part between the head of the steel bar and the cutting mechanism 3 is the length to be cut.

[0025] As Figure 1 、 Figure 2 and Figure 3As shown in the figure, the cutting mechanism 3 includes a support frame 31 and connecting blocks 35. The connecting blocks 35 are located on both sides of the support frame 31. The connecting blocks 35 are connected to the steel bar positioning assembly 5 through hydraulic devices 4. The steel bar positioning assembly 5 includes a positioning member 51, a steel bar pushing member 52, and a sliding member 53. The positioning member 51 is fixedly connected to both ends of the steel bar pushing member 52. A sliding member 53 is arranged at the bottom of the positioning member 51. The sliding member 53 is slidably connected to the track 6. The body of the hydraulic device 4 is fixed on the connecting block 35 of the cutting mechanism 3. The output end of the hydraulic device 4 is fixed on the positioning member 51 of the steel bar positioning assembly 5. When the steel bar positioning assembly 5 slides, the hydraulic device 4 drives the sliding member 53 of the steel bar positioning assembly 5 to move on the track 6, so as to achieve the effect of pushing or limiting one end of the steel bar by the steel bar pushing member 52.

[0026] As Figure 3 shown, multiple groups of arc-shaped convex members are arranged at the bottom of the steel bar pushing member 52, which are matched with the grooves with a downward arc on the cutting plane 2. The arc-shaped convex members can be perpendicular to and cover the side surface of one end of the steel bar in the groove, and stably push or limit the steel bar when the steel bar pushing member 52 is working.

[0027] As Figure 2 shown, the cutting mechanism 3 further includes a lifting member 32, a lifting cutting assembly 33, and a lifting limiting assembly 34. Two groups of lifting members 32 are arranged above the support frame 31. The lifting members 32 are respectively connected to both ends of the lifting cutting assembly 33 and the lifting limiting assembly 34. The lifting cutting assembly 33 is vertically slidably connected to the support frame 31 through the lifting member 32. The lifting limiting assembly 34 is vertically slidably connected to the support frame 31 through the lifting member 32. The lifting limiting assembly 34 moves vertically downward, and then the lifting cutting assembly 33 moves vertically downward, so that the cutting mechanism 3 first squeezes and fixes the steel bars on the bottom cutting plane 2, and then performs the cutting operation.

[0028] As Figure 4 shown, the lifting limiting assembly 34 includes a lifting plate 341 and a gasket 342. The gasket 342 is fixed to the bottom of the lifting plate 341. When squeezing and fixing the steel bars, the lifting plate 341 squeezes the steel bars downward. The gasket 342 with an upward arc groove and the cutting plane 2 with a downward groove are combined to independently limit each steel bar, which is not easy to slip off. Moreover, the gasket 342 has elasticity, increasing the contact area with the top of the steel bar, ensuring that the steel bars are stably fixed during the cutting state, and improving the quality of steel bar processing.

[0029] As Figure 5As shown in the figure, the lifting and cutting assembly 33 includes a lifting table 331 and a single-group cutting member 332. A plurality of single-group cutting members 332 are connected to the bottom of the lifting table 331. The single-group cutting member 332 includes a rotation control member 3321 and a cutting blade 3322. The single-group cutting member 332 is rotatably connected to the rotation control member 3321. There is a knife groove 21 on the cutting plane 2 directly below the cutting blade 3322. A motor is arranged inside the machine tool 1, and the output end of the motor drives the internal gear of the lifting table 331 to rotate. Thus, the rotation control member 3321 drives the cutting blade 3322 to rotate. During the downward movement of the lifting table 331, the cutting blade 3322 operates at high speed to cut the firmly fixed steel bars.

[0030] There are multiple groups of grooves on the cutting plane 2, and the positions of the single-group cutting member 332 and the gasket 342 correspond to the positions of the grooves. When the device is in processing, each steel bar is correspondingly placed in a group of grooves and the gasket 342, and is cut by the single-group cutting member 332 above it. Multiple groups of steel bars can be processed simultaneously, improving the processing efficiency.

[0031] The above are only the embodiments of the present invention. Common knowledge such as the specific structures and characteristics in the solutions is not described in detail here. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.
