Description

Technical Field

[0001] This invention relates to the field of steel bar manufacturing technology, and in particular to a steel bar cutting machine. Background Technology

[0002] Steel bars are a widely used metallic material in construction engineering. They are mainly made of carbon steel and alloy steel and have high strength and toughness. They are the "skeleton" of concrete structures, used to enhance the tensile and shear properties of concrete and improve the stability and load-bearing capacity of building structures.

[0003] A search revealed Chinese patent publication number CN222036649U, which discloses a rebar cutting machine. The machine includes a worktable with support legs fixedly installed at the four corners of its lower end face. A storage box is located on the front side of the worktable, and a cutting machine is mounted on the upper side. A connecting piece rotatably connects the cutting machine to the worktable. A handle is fixedly installed on the front end face of the cutting machine. A groove is formed on the upper end face of the worktable, and a rebar body is placed inside the groove. A fixing mechanism is located on the lower side of the worktable. This invention utilizes the fixing mechanism to drive a threaded rod to rotate using a motor, causing a threaded sleeve connected to the two ends of the threaded rod's outer surface to rotate. For displacement, two sets of threaded sleeves each carry a set of clamps through a support rod. The two sets of clamps move synchronously towards the main body of the reinforcing bar and fix the main body of the reinforcing bar. Then the cutting machine can be started, and the reinforcing bar can be cut by pressing down with the handle. However, due to aging and improper assembly of the hydraulic pump, oil cylinder, and oil pipe joint seals, oil leakage is likely to occur. High-pressure resistant fluororubber sealing rings are now used to replace traditional rubber seals to improve sealing performance and aging resistance. The joint adopts a conical seal and O-ring + retaining ring combination structure, but it lacks a precise positioning baffle. The reinforcing bar is prone to skew when it is fed in, and manual adjustment is required repeatedly. This not only reduces efficiency, but also increases safety risks due to the hands being close to the cutting area. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a rebar cutting machine, which aims to improve the existing technology by addressing the lack of a precise positioning baffle, the tendency of rebars to be skewed when fed in, the need for repeated manual adjustments, which not only reduces efficiency but also increases safety risks due to the proximity of the hands to the cutting area.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rebar cutting machine, comprising a machine body, a fixing plate fixedly connected to the left side of the inner wall of the machine body, a support frame fixedly connected to the left side of the top wall of the machine body, a clamping mechanism installed on the left side of the top wall of the fixing plate, the clamping mechanism being used to fix the rebar, and a fixing mechanism installed on the inner side of the support frame, the fixing mechanism being used to fix the cutting tool; the clamping mechanism includes a housing, the housing being fixedly connected to the left side of the top wall of the fixing plate, and a hydraulic rod fixedly connected to the middle of the inner bottom wall of the housing.

[0006] With the above technical solution: once the hydraulic rod is activated, it pushes the fixed block to move up and down.

[0007] As a further description of the above technical solution: Multiple clamping blocks are equidistantly slidably connected to the upper part of the inner wall of the outer shell. A locking block is fixedly connected to the bottom of the clamping block, and a groove is provided on the inner side of the locking block.

[0008] The above technical solution uses clamps to fix the reinforcing bars, preventing them from tilting when being fed in. It eliminates the need for repeated manual adjustments and can also fix and clamp reinforcing bars of different sizes, thus expanding its application range.

[0009] As a further description of the above technical solution: A fixing block is fixedly connected to the top of the hydraulic rod, and protrusions are fixedly connected to the front and rear sides of the outer wall of the fixing block. The protrusions are slidably connected to the inner wall of the groove.

[0010] With the above technical solution: when the fixed block moves, the protrusion slides in the groove of the locking block. When the fixed block pushes out, it compresses the locking block, causing the locking block to move to both sides. When the fixed block descends, it pulls the locking block to bring it together in the middle, thus allowing the locking block to open and close.

[0011] As a further description of the above technical solution: The fixing mechanism includes a fixing frame, which is fixedly connected to the middle of the inner top wall of the support frame. A hydraulic rod is fixedly connected to the inner top wall of the fixing frame, and sliding columns are fixedly connected to the front and rear sides of the inner wall of the fixing frame.

[0012] The above technical solution involves a hydraulic rod that pushes a slider to move up and down along a sliding column, with a blade installed on the left side of the slider.

[0013] As a further description of the above technical solution: The bottom end of the hydraulic rod 2 is fixedly connected to a slider, which is slidably connected to the outer wall of the slide column. A blade is installed on the left side of the outer wall of the slider.

[0014] The above technical solution allows the slider to slide on the slide bar, preventing the blade from shifting due to uneven heights on both sides.

[0015] As a further description of the above technical solution: The outer wall of the blade is connected to a plurality of bolts 1 at equal intervals on the upper left side. The ends of the bolts 1 are threaded to the inner wall of the blade. The top wall of the slider is connected to a plurality of bolts 2 at equal intervals. The lower outer wall of the bolts 2 is threaded to the inner wall of the blade.

[0016] The above technical solution involves two bolts at the top of the slider. Bolt 2 passes through the top of the slider and is screwed into the inner wall of the blade. Bolt 1 is also screwed into the side of the blade and fixed to the inner wall of the slider. Bolt 1 and Bolt 2 can fix the blade to the slider.

[0017] As a further description of the above technical solution: A transmission groove is installed on the right side of the top wall of the machine body, and a controller is installed on the right side of the front end of the outer wall of the machine body.

[0018] Through the above technical solution: the transmission groove guides the steel bar into the cutting area in a straight line to prevent skewing; the controller can receive signals transmitted from sensors in various parts of the equipment and analyze and process these signals according to the preset program logic to realize the automated operation of the steel bar cutting process.

[0019] As a further description of the above technical solution: A display screen is fixedly connected to the right side of the top wall of the controller, and a power supply cabinet is installed on the right side of the outer wall of the controller.

It can clamp the steel bars placed on the top wall of the machine body, fix the steel bars, and prevent the steel bars from being easily skewed when they are fed in. There is no need for repeated manual adjustment. It can also fix and clamp steel bars of different types, thus improving the scope of use.

[0022] 2. In this utility model, the hydraulic rod 2 pushes the slider to move up and down along the slide column. The left side of the slider is equipped with a blade.

[0029] Working principle: When the hydraulic rod 405 starts working, it pushes the fixed block 404 connected to it to move upward. During the upward movement of the fixed block 404, the protrusion 406 on its side will slide smoothly along the groove 407 inside the locking block 403. As the fixed block 404 continues to rise, its top will gradually press against the inside of the locking block 403, forcing the locking block 403 to open to both sides. Conversely, when the hydraulic rod 405 retracts, the fixed block 404 will move downward. At this time, the protrusion 406 will drive the locking block 403 to move closer to the center. Through this reciprocating motion, the locking block 403 can achieve regular opening and closing actions. This design can firmly clamp the steel bar placed on the top of the machine body 1, effectively preventing the steel bar from tilting during the conveying process, saving the trouble of frequent manual adjustment. At the same time, due to the adjustment of the opening and closing range of the locking block 403, it can adapt to steel bars of different diameters and specifications, greatly improving the applicability and practicality of the equipment. When the hydraulic rod 501 is working, it drives the slider 504 to move up and down along the vertically installed slide column 503. The blade 505 is installed on the left side of the slider 504. The guiding effect of the slide column 503 ensures that the blade 505 remains horizontal during the cutting process, avoiding the cutting offset problem caused by the uneven height on both sides. Two bolts 507 are provided on the top of the slider 504. These bolts pass through the upper surface of the slider 504 and are screwed into the threaded hole at the top of the blade 505. At the same time, a bolt 506 is provided on the side of the blade 505. This bolt passes through the side wall of the blade 505 and is fastened in the internal threaded hole of the slider 504. This double fixing method not only makes the connection between the blade 505 and the slider 504 more secure and reliable, but also facilitates the installation, disassembly and replacement of the blade 505 by the operator, greatly improving maintenance efficiency and operation convenience.
