Description

Technical Field

[0001] This utility model is a rebar cutting machine, belonging to the field of rebar. Background Technology

[0002] Reinforcing bars refer to steel used in reinforced concrete and prestressed reinforced concrete. During construction, it is necessary to cut reinforcing bars on-site to meet construction requirements. A reinforcing bar cutting machine with patent number CN202420671957.8 describes a machine that uses multiple fixed frames, cutting blades, clamps and support rods to cooperate with each other, which facilitates the cutting of the reinforcing bar into equal length segments, avoids the need for disassembly and fixing during the cutting process, and improves adjustment efficiency.

[0003] Therefore, according to the aforementioned patent, it is known that equal-segment cutting of steel bars can be achieved. However, before cutting, the steel bars may be bent. The patent does not describe any straightening or correcting components before cutting, so it is impossible to straighten the bent steel bars. When cutting bent steel bars, it is impossible to accurately obtain equal-segment cut steel bars, thus failing to guarantee the straightness of the steel bars. Consequently, the length and straightness of the cut steel bars do not meet the actual production requirements. Therefore, this utility model proposes a correctable steel bar cutting machine. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rebar cutting machine.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A rebar cutting machine includes a base, on which two U-shaped sliding rods are fixedly mounted. A setting seat is slidably mounted on each U-shaped sliding rod in conjunction with a sliding sleeve. A cutting component is connected to the setting seat via a lifting assembly. The cutting component has a cutting blade disc. A stop plate is fixedly mounted on the base. Scale lines are engraved on the U-shaped sliding rods. An adjustment knob is threadedly connected to the sliding sleeve. A lower U-shaped seat is slidably mounted on the base in conjunction with rollers. An upper U-shaped seat is mounted on the lower U-shaped seat. A straightening wheel is rotatably mounted on the inner side of both the lower and upper U-shaped seats in conjunction with bearings. A drive assembly for driving the straightening wheel is mounted on the outer side of both the lower and upper U-shaped seats. An adjustment assembly for adjusting the upper U-shaped seat is also mounted on the lower U-shaped seat.

[0007] Furthermore, the lifting assembly is an electric telescopic rod fixed on the mounting base, and the output bottom end of the electric telescopic rod is fixedly provided with a mounting base. The cutting assembly is a cutting motor set inside the mounting base, and the output end of the cutting motor is connected to the cutting disc.

[0008] Furthermore, two hydraulic cylinders are mounted on the sliding sleeve in conjunction with the bracket. Each hydraulic cylinder is equipped with a clamping plate. There are two brackets, which are arranged symmetrically to each other.

[0009] Furthermore, a collection frame is provided on the bracket, and multiple smooth telescopic components are provided between the mounting base and the setting base. The smooth telescopic components include a lower sleeve and an upper insertion rod. The upper insertion rod is slidably inserted into the lower sleeve, and multiple vertical grooves are provided on the lower sleeve. The bottom of the upper insertion rod slides within the vertical grooves in a limited manner.

[0010] Furthermore, the drive assembly includes meshing gears connected to one side of the straightening wheel via round rods. The meshing gears are rotatably mounted on the outer wall of one side of the lower U-shaped seat and the upper U-shaped seat. A transmission chain connects the meshing gears. A drive motor is provided on the other side of both the lower U-shaped seat and the upper U-shaped seat. The output rod of the drive motor passes into the lower U-shaped seat and the upper U-shaped seat and is connected to one of the meshing gears.

[0011] Furthermore, the outer surfaces of the lower U-shaped seat and the upper U-shaped seat are also equipped with a secondary meshing gear that is rotatably connected to the secondary bearing. The secondary meshing gear also meshes with the transmission chain. The adjustment component includes a fixed frame fixed on the lower U-shaped seat, and a secondary electric telescopic rod connected to the upper U-shaped seat is provided on the fixed frame.

[0012] Furthermore, a connecting plate is fixed between the collection frame and the lower U-shaped seat, and a water tank is also fixed on the connecting plate. The water tank is a transparent box with a built-in water filling pipe and a drain pipe with a blockage block. Multiple auxiliary rollers are set at the bottom of the water tank, and a high-pressure pump is set at the top of the water tank. The suction pipe of the high-pressure pump is located in the water tank, and the high-pressure pump has a water outlet pipe.

[0013] Furthermore, several nozzles are connected to the water outlet pipe via flexible hoses, and the water outlet pipe and nozzles are connected by connecting rods. A filter frame is fixed inside the collection frame with screws, and a filter screen is installed inside the filter frame.

[0014] The beneficial effects of this utility model are:

[0015] By setting up the lower and upper U-shaped seats, the steel bars to be cut are passed through the upper and lower straightening wheels and rolled in conjunction with the straightening wheels to transport the steel bars. During the transportation process, the bent and crooked steel bars are effectively straightened, because only straight steel bars can be cut to the required length.

[0016] The required cutting length can be intuitively determined by manually moving the sliding sleeve on the U-shaped sliding rod and using the scale lines. The cutting point of the cutting blade corresponds to the facing surface of the setting seat. In other words, the end face of the setting seat facing the cutting blade is on the same vertical and horizontal plane as the cutting blade. Therefore, the distance moved can be intuitively determined, which is the length of the steel bar to be cut. This utility model is simple to set up and is mainly designed to correct the steel bar in advance before cutting, so that the required length of the steel bar to be cut can be accurately determined.

[0025] 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.

[0026] Please see Figure 1-4This utility model provides a rebar cutting machine, including a base 1, on which two U-shaped sliding rods 2 are fixedly mounted. A setting seat 4 is slidably mounted on the U-shaped sliding rods 2 in conjunction with a sliding sleeve 3. A cutting component is connected to the setting seat 4 via a lifting assembly. The cutting component has a cutting blade disc 5. A mating plate 6 is fixedly mounted on the base 1. Scale lines are engraved on the U-shaped sliding rods 2. An adjustment knob 7 is threadedly connected to the sliding sleeve 3. A lower U-shaped seat 8 is slidably mounted on the base 1 in conjunction with rollers. An upper U-shaped seat 9 is mounted on the lower U-shaped seat 8. A straightening wheel 10 is rotatably mounted on the inner side of both the lower U-shaped seat 8 and the upper U-shaped seat 9 in conjunction with bearings. A drive assembly for driving the straightening wheel 10 is mounted on the outer side of both the lower U-shaped seat 8 and the upper U-shaped seat 9. An adjustment assembly for adjusting the upper U-shaped seat 9 is also mounted on the lower U-shaped seat 8.

[0027] See Figure 1 and Figure 3 The lifting assembly is an electric telescopic rod 11 fixed on the mounting base 4. The output bottom end of the electric telescopic rod 11 is fixedly provided with a mounting base 12. The cutting assembly is a cutting motor 13 located inside the mounting base 12. The output end of the cutting motor 13 is connected to the cutting disc 5. The electric telescopic rod 11 drives the cutting motor 13 to descend, thus driving the cutting disc 5 to descend, so that normal cutting work can be achieved.

[0028] See Figure 4 Two hydraulic cylinders 15 are installed on the sliding sleeve 3 in conjunction with the bracket 14. The hydraulic cylinders 15 are equipped with clamping plates 16. There are two brackets 14, which are symmetrically arranged. The hydraulic cylinders 15 work with the clamping plates 16 to clamp the steel bars and ensure the cutting stability.

[0029] See Figure 3 and Figure 5 The bracket 14 is equipped with a collection frame 17. Multiple smooth telescopic components are provided between the mounting base 12 and the setting base 4. The smooth telescopic components include a lower sleeve 20 and an upper insertion rod 21. The upper insertion rod 21 is slidably inserted into the lower sleeve 20, and multiple vertical grooves 22 are opened on the lower sleeve 20. The bottom of the upper insertion rod 21 slides within the vertical grooves 22 in a limited manner. When the cutting disc 5 descends to cut, the lower sleeve 20 and the upper insertion rod 21 move in an interlocking manner to ensure a more stable descent and smooth cutting.

[0030] See Figure 2The drive assembly includes meshing gears 23 connected to one side of the straightening wheel 10 via round rods. The meshing gears 23 are rotatably mounted on the outer wall of one side of the lower U-shaped seat 8 and the upper U-shaped seat 9. A transmission chain 24 connects the meshing gears 23. A drive motor is provided on the other side of both the lower U-shaped seat 8 and the upper U-shaped seat 9. The output rod of the drive motor passes through the lower U-shaped seat 8 and the upper U-shaped seat 9 and is connected to one of the meshing gears 23. A secondary meshing gear 25 is also rotatably connected to the outer side of the lower U-shaped seat 8 and the upper U-shaped seat 9 with a secondary bearing. The secondary meshing gear 25 also meshes with the transmission chain 24. The adjustment assembly includes a fixed frame fixed on the lower U-shaped seat 8. The fixed frame is provided with a secondary electric telescopic rod 26 connected to the upper U-shaped seat 9. There are multiple secondary electric telescopic rods 26, which drive the upper U-shaped seat 9 to descend, so that the straightening wheels above and below it can better contact the steel bars and complete the straightening of the steel bars. The meshing gear 23, in conjunction with the transmission chain 24, drives all the straightening wheels to rotate, ensuring the straightening work. The auxiliary meshing gear 25 meshes with the transmission chain 24, and the function of the auxiliary meshing gear 25 is to squeeze the transmission chain 24, so that the transmission chain 24 and the meshing gear in the middle part have a wrap angle of at least 120 degrees.

[0031] See Figure 1 and Figure 6 A connecting plate 18 is fixed between the collecting frame 17 and the lower U-shaped seat 8. A water tank 19 is also fixed on the connecting plate 18. The water tank 19 is a transparent box with its own water inlet pipe and drain pipe with a blockage block. Multiple auxiliary rollers are set at the bottom of the water tank 19, and a high-pressure pump 32 is set at the top of the water tank 19. The suction pipe of the high-pressure pump 32 is located in the water tank 19. The high-pressure pump 32 has a water outlet pipe 27, and several hoses 28 are connected to the nozzles 29 on the water outlet pipe 27. The water outlet pipe 27 and the nozzles 29 are also connected by a connecting rod 30. A filter frame 31 is fixed inside the collecting frame 17 with screws. A filter screen is set inside the filter frame 31. The high-pressure pump 32 draws water, which is sprayed out in conjunction with the water outlet pipe 27, hoses 28 and nozzles 29. Due to high friction, high temperature heat will be generated. The nozzle 29, positioned near the cutting head, sprays water onto the edge of the cutting head to suppress dust generated during cutting. Cutting debris falls onto a filter screen with the water flow, where it is filtered. Clean water flows to the bottom of the collection frame 17. Note that a pipe connector is located at the bottom of the collection frame 17, and a detachable pipe connects this connector to the water supply pipe of the water tank 19. The filtered water is then drained into the water tank 19 for recycling. When there is excessive debris, the filter screen can be disassembled for cleaning. The connecting rod 30 is a retractable, fixed-position bracket. Specifically, the connecting rod 30 is a "lazy bracket" that automatically positions itself after being moved, allowing the nozzle to be adjusted to face the desired water spray position. Note that... Figure 1The front end of the collection frame 17 has a support plate with an arc groove, which can serve to support the steel bars.

[0032] In use, the steel bar to be cut is passed through the upper and lower straightening wheels 10 via the lower U-shaped seat 8 and the upper U-shaped seat 9. The straightening wheels 10 are used to roll and transport the steel bar. During the transport process, the bent or crooked steel bars are effectively straightened, because only straight steel bars can be cut to the required length. The sliding sleeve 3 is manually moved on the U-shaped sliding rod 2, and the required cutting length can be intuitively known with the help of the scale lines. The cutting point of the cutting disc 5 corresponds to the facing surface of the setting seat 4. That is to say, the end face of the setting seat 4 facing the cutting disc 5 is on the same vertical and horizontal plane as the cutting disc 5. Therefore, the distance moved can be intuitively known, which is the length of the steel bar to be cut. This utility model is simple to set up and is mainly for straightening the steel bar in advance before cutting, so that the required length of the steel bar to be cut can be accurately known.

[0033] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
