Description

Technical Field

[0001] This invention relates to the field of steel bar processing technology, specifically to an automated steel bar cutting device. Background Technology

[0002] Steel reinforcement is an indispensable building material in many fields, including construction engineering. During construction, steel reinforcement needs to be cut to specific lengths according to design requirements, and the quantity processed must be precisely controlled. Traditional steel reinforcement cutting mainly relies on manual operation, with workers using simple tools such as manual steel reinforcement cutters. This method has many drawbacks: firstly, manual operation is extremely inefficient, making it difficult to meet the quantity requirements of large-scale construction projects, seriously affecting project progress; secondly, manually measuring and cutting steel reinforcement lengths is difficult to guarantee consistent accuracy, easily leading to length deviations, resulting in inaccurate installation of steel reinforcement in subsequent construction, affecting the stability and quality of the building structure. With the rapid development of the construction industry and the ever-increasing demands for project quality and efficiency, there is an urgent need for equipment that can automatically cut steel reinforcement and precisely control the quantity and length dimensions processed to replace traditional manual operation methods, improve the efficiency and quality of steel reinforcement processing, and ensure the smooth progress of construction projects.

[0064] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0065] To achieve the above objectives, the present invention provides the following technical solutions, such as... Figure 1-3 As shown, an automated rebar cutting device includes:

[0066] The system includes a feeding device 1, a distributing device 2, a conveying structure 3, a measuring device 4, and a cutting device 5; wherein the feeding device 1 and the conveying structure 3 are mounted on the main support 6; the distributing device 2 is mounted on the feeding device 1; the measuring device 4 is located at the output end of the conveying structure 3; and the cutting device 5 is located in the middle of the conveying structure 3.

[0067] Bundles of steel bars are placed on the feeding device 1. The feeding device 1 then breaks up the bundles of steel bars and lays them flat on the feeding device 1. The sorting device 2 separates a portion of the steel bars from the feeding device 1 according to the required processing quantity and sends it to the conveying structure 3. The conveying structure 3 transports the steel bars to the measuring device 4 and the cutting device 5. The measuring device 4 measures the length of the steel bars, and the cutting device 5 cuts the steel bars of the appropriate length. The cutting steel bars are then transported outward by the conveying structure 3.

[0068] Furthermore, such as Figure 4-8 As shown, the feeding device 1 is installed at the feeding end of the automated rebar cutting equipment; the feeding device 1 is rotatably installed on the top of the main support 6; the feeding device 1 includes a feeding frame 101, a vibration motor 102, a linkage baffle structure 103, and an angle adjustment cylinder 104.

[0069] The feeding rack 101 is a rectangular frame structure, wherein the setting height of the feeding rack 101 is higher than the setting height of the conveying structure 3, so as to facilitate the rebar to slide from the feeding rack 101 onto the conveying structure 3; the feeding rack 101 includes a frame at both ends and several welded crossbeams with intervals inside the frame; further, a sliding column 105 is provided on the upper surface of the crossbeam along the direction of the extension of the crossbeam, the sliding column 105 is a cylindrical rebar with a smooth outer surface, the rebar to be cut is placed on the sliding column 105, the sliding column 105 is used to reduce the contact area between the rebar to be cut and the feeding rack 101, reduce the friction, and make it easier for the rebar to be cut to slide along the sliding column 105 on the feeding rack 101;

[0070] The lower end of the angle adjusting cylinder 104 is hinged to the main support 6, and the upper end of the angle adjusting cylinder 104 is hinged to the feeding rack 101. Since the feeding rack 101 is installed on the top of the main support 6, and the middle part of the feeding rack 101 is hinged to the top of the main support 6, the angle adjusting cylinder 104 can drive the feeding rack 101 to rotate, thereby adjusting the tilt angle of the feeding rack 101, so that the steel bars can converge towards the linkage retaining structure 103 under the action of vibration and gravity.

[0071] The linkage blocking structure 103 is set at the discharge end of the feeding frame 101 to block the reinforcing bars.

[0072] Vibration motor 102 is fixed to the lower surface of the crossbeam, and several can be installed. Initially, the loading rack 101 is in a horizontal position. Bundles of steel bars to be cut are placed on the loading rack 101 by a crane. Since the steel bars are piled up together and cannot be sorted in the next step, the vibration motor 102 needs to generate vibration to disperse the steel bars piled up on the loading rack 101 and spread them flat on the loading rack 101. Then, the vibration continues, and at the same time, the angle adjustment cylinder 104 drives the loading rack 101 to tilt slightly downward in the direction of the conveying structure 3. At this time, the steel bars on the loading rack 101 will gradually converge in the downward slope direction along the downward tilting loading rack 101 during the vibration. Finally, the steel bars are neatly arranged on the loading rack 101 and blocked by the linkage baffle plate 1031, which facilitates the next step of sorting.

[0073] Furthermore, such as Figure 4 , 5 As shown in Figure 8, the linkage baffle structure 103 includes several linkage baffle plates 1031, a linkage rod 1032, and a telescopic cylinder 1033.

[0074] Several linkage baffles 1031 are sequentially installed on the side frame of the feeding rack 101 near the conveying structure 3. The middle part of the linkage baffle 1031 is hinged to the side frame of the feeding rack 101, and the lower part of the linkage baffle 1031 is hinged to the connecting rod 1032. One end of the connecting rod 1032 is connected to the telescopic cylinder 1033. In the initial state, the top of the linkage baffle 1031 exceeds the height of the steel bars of the feeding rack 101, which is used to block the steel bars and control them on the feeding rack 101. During operation, the telescopic cylinder 1033 drives the connecting rod 1032, and the connecting rod 1032 drives all the linkage baffles 1031 to rotate downward. Finally, the linkage baffles 1031 rotate to a position lower than the upper surface of the feeding rack 101. At this time, the steel bars are no longer blocked and can move towards the conveying structure 3.

[0075] Furthermore, such as Figure 4-7 As shown, the material distribution device 2 includes multiple synchronously moving material distribution structures, which are hinged at intervals below the loading frame 101.

[0076] A single material distribution structure includes a cylinder support 201, a lifting cylinder 202, a pushing cylinder 203, a positioning cylinder 204, a material distribution fork 205, and a positioning fork 206; both the material distribution fork 205 and the positioning fork 206 are L-shaped structures.

[0077] One end of the cylinder bracket 201 is hinged to the side frame of the feeding rack 101 away from the conveying device, and the other end is hinged to the telescopic end of the lifting cylinder 202; the bottom of the lifting cylinder 202 is hinged to the lower end of the main support 6; the lifting cylinder 202 drives one end of the cylinder bracket 201 to rise or fall.

[0078] The pushing cylinder 203 and the positioning cylinder 204 are mounted side by side on the cylinder bracket 201; a separating fork 205 is fixed on the telescopic end of the pushing cylinder 203; a positioning fork 206 is fixed on the telescopic end of the positioning cylinder 204.

[0079] In the initial state, the cylinder support 201 is in the lowered position. At this time, the height of the material distribution structure does not exceed the upper surface of the feeding frame 101, and will not affect the feeding device 1 to vibrate and sort the steel bars on the feeding frame 101.

[0080] When the material distribution structure is needed for material distribution, the pushing cylinder 203 and the positioning cylinder 204 synchronously extend and retract to adjust their positions according to the required quantity of material to be distributed. Then, the lifting cylinder 202 drives the cylinder support 201 to rise. As the cylinder support 201 rises, the distributing fork 205 and the positioning fork 206 gradually extend upward from below the loading rack 101. Finally, the tops of the distributing fork 205 and the positioning fork 206 exceed the height of the reinforcing bars on the loading rack 101. At this time, the distributing fork 205 and the positioning fork 206 are on the same working surface, dividing the reinforcing bars on the loading rack 101 into two parts. One part is located between the linkage baffle plate 1031 and the distributing fork 205 and the positioning fork 206. This part contains the reinforcing bars that need to be processed; the other reinforcing bars are located above the separating fork 205 and the positioning fork 206, and this part is separated for the next processing. Since the outer diameter of the reinforcing bars in the same batch is the same, the extension and retraction of the pushing cylinder 203 and the positioning cylinder 204 are adjusted accordingly to determine the number of reinforcing bars to be separated. By adjusting the extension and retraction of the pushing cylinder 203 and the positioning cylinder 204, the extension and retraction is made equal to the number of reinforcing bars to be separated multiplied by the diameter of the reinforcing bars. In this way, the distance between the linkage baffle 1031 and the separating fork 205 and the positioning fork 206 can be controlled. This distance can be used to separate the required number of reinforcing bars, thereby obtaining the required number of reinforcing bars.

[0081] Subsequently, the positioning fork 206 stops in its original position, the linkage baffle 1031 opens, and the separating fork 205 is pushed downward under the drive of the pushing cylinder 203, pushing the steel bars between the linkage baffle 1031 and the separating fork 205 towards the conveying structure 3, thereby completing the steel bar separation work; after the separation work is completed, the linkage baffle 1031 closes, the lifting cylinder 202 drives the cylinder bracket 201 to descend, so that the tops of the separating fork 205 and the positioning fork 206 are lowered below the loading rack 101. At this time, the remaining steel bars can repeat the work of the loading device 1. The vibration motor 102 vibrates to make the remaining steel bars spread flat and arranged in sequence on the loading rack 101, and then the next separation work of the separating device 2 can continue.

[0082] Furthermore, such as Figure 4 and 6As shown, on the side of the loading rack 101 near the conveying structure 3, there is an inclined surface extending towards the conveying structure 3. The steel bars slide down the inclined surface onto the conveying structure 3 under the push of the splitting fork 205.

[0083] Furthermore, such as Figure 9-12 As shown, the material conveying structure 3 includes a transverse displacement structure 301 and a longitudinal displacement structure 302;

[0084] The lateral displacement structure 301 includes a motor 3011, a main drive shaft 3012, a conveying chain 3013, a drive sprocket 3014, and a driven sprocket 3015;

[0085] The main drive shaft 3012 is rotatably mounted on the main support 6 via a bearing seat. The main drive shaft 3012 is connected to the motor 3011. The motor 3011 is located at the lower part of the main support 6, and the motor 3011 drives the main drive shaft 3012 to rotate.

[0086] Several drive sprockets 3014 are fixed to the main drive shaft 3012 at intervals; the number of driven sprockets 3015 matches that of drive sprockets 3014, and the driven sprockets 3015 are rotatably mounted on the main support 6 on the side away from the drive sprockets 3014; the conveying chain 3013 is fitted onto the drive sprockets 3014 and the driven sprockets 3015; the outer diameter of the drive sprocket 3014 is larger than that of the driven sprockets 3015, and the upper end of the conveying chain 3013 exhibits a motion trajectory that continuously descends in the direction of the longitudinal displacement structure 302;

[0087] The steel bars roll off the feeding rack 101 onto the conveying chain 3013 of the transverse displacement structure 301. Driven by the conveying chain 3013, the steel bars move toward the longitudinal displacement structure 302 and eventually roll onto the longitudinal displacement structure 302.

[0088] The longitudinal displacement structure 302 is a roller conveyor belt; the roller conveyor belt is composed of rollers, bearings and a frame. The rollers are connected to the transmission structure and drive the rollers to rotate, thereby driving the steel bars on the roller conveyor belt to move forward. The specific structure of the roller conveyor belt is prior art and will not be described in detail in this application.

[0089] Furthermore, such as Figure 9-12 As shown, several second guide frames 304 are also provided between the transverse displacement structure 301 and the longitudinal displacement structure 302. The second guide frames 304 are wedge-shaped structures, and the several second guide frames 304 are arranged along the length direction of the main support 6 and fixed above the main support 6; the second guide frames 304 are located between the transverse displacement structure 301 and the longitudinal displacement structure 302. Their function is to guide the reinforcing bars from the transverse displacement structure 301, along the second guide frames 304, onto the longitudinal displacement structure 302;

[0090] Furthermore, a blocking slider 3016 is also provided on the second guide frame 304. Correspondingly, a slide rail 401 is opened on the second guide frame 304 along the vertical direction. The blocking slider 3016 is set in the slide rail 401 and is slidably connected to the inner wall of the slide rail 401. The lower end of the blocking slider 3016 is connected to the slider connecting rod 3017. The slider connecting rod 3017 is connected to the cylinder. The cylinder drives the slider connecting rod 3017 and the blocking slider 3016 to move up and down. The blocking slider 3016 can control the stopping or conveying of the steel bar on the transverse displacement structure 301. When it is necessary to feed material to the longitudinal displacement structure 302, the blocking slider 3016 slides down, and its top end is lower than the upper surface of the second guide frame 304. At this time, the steel bar can move to the longitudinal displacement structure 302 under the drive of the transverse displacement structure 301.

[0091] Furthermore, such as Figure 9-11 As shown, a first guide frame 303 is also provided between the feeding device 1 and the conveying structure 3; the first guide frame 303 is fixed above the main support 6, and the side frame of the feeding frame 101 near the conveying structure 3 will press against the top of the first guide frame 303 when it tilts downward; a number of wedge blocks are also provided on the side wall of the first guide frame 303 near the transverse displacement structure 301, and the number of wedge blocks are at the same height. The steel bars separated from the material distribution device 2 slide along the inclined surface of the wedge blocks onto the transverse displacement structure 301.

[0092] Furthermore, such as Figure 12-15 As shown, the measuring device 4 includes a slide rail 401, a sliding platform 402, and a baffle 403; the slide rail 401 is disposed on the side of the conveying structure 3; the slide rail 401 is disposed along the length of the conveying structure 3.

[0093] The sliding platform 402 is snapped onto the slide rail 401 and is slidably connected to the slide rail 401;

[0094] The baffle 403 is hinged to the sliding platform 402. The middle part of the baffle 403 is hinged to the sliding platform 402. The side of the baffle 403 away from the material conveying structure 3 is connected to the cylinder. The cylinder drives the baffle 403 to rotate up and down.

[0095] Initially, the baffle 403 is tilted upwards and suspended above the conveying structure 3, without affecting the conveying of the reinforcing bars. When a certain length of reinforcing bar needs to be cut, the position of the sliding platform 402 is adjusted so that the sliding platform 402 is closer to or farther from the cutting device 5. The distance from the cutting device 5 to the baffle 403 is the length of the reinforcing bar to be cut. The cylinder drives the baffle 403 to rotate downwards and block the path of the reinforcing bar conveying. As the conveying structure 3 conveys the reinforcing bar, it moves from the cutting device 5 to the baffle 403 and is eventually intercepted by the baffle 403. At this time, the distance between the cutting device 5 and the baffle 403 is the length of the reinforcing bar to be cut. Moreover, the baffle 403 also plays a role in aligning the reinforcing bars. The reinforcing bars transported on the conveying structure 3 may be positioned too far forward or too far back and not in the same position. At this time, the baffle 403 can block the reinforcing bars, so that the reinforcing bars that are too far forward or too far back are neatly placed against the side of the baffle 403, aligning the reinforcing bars and facilitating the next cutting work. In this way, the length of the cut reinforcing bars is consistent.

[0096] Multiple measuring devices 4 can be arranged along the slide rail 401. The positions of multiple measuring devices 4 can be preset to correspond to different cut lengths.

[0097] Furthermore, such as Figure 13-15 As shown, the slide 401 has a T-shaped cross-section; the sliding platform 402 includes a movable slider 4021, a fixed slider 4022, an adjusting handwheel 4023, and a support bracket 4024;

[0098] Both the movable slider 4021 and the fixed slider 4022 have H-shaped cross-sections, and the movable slider 4021 and the fixed slider 4022 are respectively snapped onto the upper and lower sides of the slide rail 401;

[0099] The fixed slider 4022 is fixedly installed on the support bracket 4024 and located directly below the movable slider 4021; the fixed slider 4022 is snapped into the lower side of the slide rail 401;

[0100] The support bracket 4024 is provided with a guide groove; the rear part of the movable slider 4021 is slidably connected to the guide groove; the front part of the movable slider 4021 is engaged with the upper side of the slide rail 401; the top of the movable slider 4021 is connected to the adjusting handwheel 4023.

[0101] The adjusting handwheel 4023 is located on the top of the support bracket 4024. The lower end of the adjusting handwheel 4023 is provided with a threaded rod, which is threadedly connected to the support bracket 4024. The threaded rod penetrates the top of the support bracket 4024 and is connected to the top of the movable slider 4021. By rotating the adjusting handwheel 4023, the movable slider 4021 is driven to move up and down.

[0102] When it is necessary to move the measuring device 4, rotate the adjusting handwheel 4023 upward to move the movable slider 4021 upward. At this time, the movable slider 4021 and the fixed slider 4022 will not clamp the slide rail 401, and the measuring device 4 can be moved. When the measuring device 4 is moved to the required position, rotate the adjusting handwheel 4023 downward to move the movable slider 4021 downward. The movable slider 4021 and the fixed slider 4022 will continuously approach each other and eventually clamp the slide rail 401, completing the clamping and positioning work.

[0103] Furthermore, a reinforcing bracket is also provided on the side of the supporting bracket 4024. The reinforcing bracket is used to install the baffle 403 and to provide auxiliary reinforcement and support for the baffle 403.

[0104] The reinforcing bracket includes a first fixing plate 4025, a second fixing plate 4026, and a hinge shaft 4027;

[0105] The first fixing plate 4025 and the second fixing plate 4026 are fixed to the side of the support bracket 4024 with a gap; the distance between the first fixing plate 4025 and the second fixing plate 4026 is equal to the thickness of the baffle 403; the space between the first fixing plate 4025 and the second fixing plate 4026 serves as the installation space for the baffle 403; the setting direction of the first fixing plate 4025 and the second fixing plate 4026 is perpendicular to the transmission direction of the material conveying structure 3, ensuring that the setting direction of the baffle 403 is also perpendicular to the transmission direction of the material conveying structure 3;

[0106] Both the first fixing plate 4025 and the second fixing plate 4026 have through holes for installing the hinge shaft 4027. The hinge shaft 4027 passes through the first fixing plate 4025, the baffle 403 and the second fixing plate 4026 in sequence, and hinges the baffle 403 and the first fixing plate 4025, the baffle 403 and the second fixing plate 4026 together.

[0107] The first fixing plate 4025 and the second fixing plate 4026 have a certain thickness to ensure strength. The first fixing plate 4025 and the second fixing plate 4026 are rectangular plate structures to maximize the contact area with the baffle 403, give the baffle 403 more support and reinforcement, prevent the baffle 403 from deforming or displacing due to the impact of the steel bar when it comes into contact with the steel bar, and ensure the alignment accuracy of the steel bar.

[0108] Furthermore, such as Figure 12 and 16 As shown, the cutting device 5 is a hydraulic cutting machine; the hydraulic cutting machine includes a clamping part and a cutting part; the part of the hydraulic cutting machine near the feed end is the clamping part, and the other part is the cutting part;

[0109] The clamping section and the cutting section have similar structures and are both hydraulic cutting devices. The difference is that the clamping section is equipped with two clamping plates, one above the other, which are driven by a hydraulic cylinder to clamp and fix the steel bar before cutting to prevent it from moving during the cutting process. The cutting section is equipped with two cutting blades, one above the other, which are driven by a hydraulic cylinder to cut the fixed steel bar. The specific principle of the hydraulic cutting device is existing technology and will not be elaborated in this application.

[0110] Furthermore, a positioning switch is also provided. The positioning switch is fixed on the main support 6 and located below the end of the feeding rack 101 near the conveying structure 3. When the angle adjusting cylinder 104 drives the feeding rack 101 to rotate and tilt towards the conveying structure 3, the lower end of the feeding rack 101 presses against the positioning switch, thereby closing the angle adjusting cylinder 104 and allowing the feeding rack 101 to reach the predetermined tilt angle. This tilt angle ensures that the steel bars can slide down the tilt angle without causing the laid-out steel bars to roll and pile up. This will not affect the next step of material distribution.

[0111] Working principle:

[0112] Bundles of steel bars are placed on the feeding rack 101 of the feeding device 1. The vibration motor 102 is started to generate vibration, causing the steel bars to spread out and lay flat. At the same time, the angle adjustment cylinder 104 adjusts the tilt angle of the feeding rack 101. Under the action of vibration and gravity, the steel bars converge and arrange themselves towards the linkage baffle structure 103. The lifting cylinder 202 of the distributing device 2 lifts the cylinder 202 bracket 201 as needed, causing the pushing cylinder 203 and the positioning cylinder 204 to drive the distributing fork 205 and the positioning fork 206 to extend out of the feeding rack 101. The extension and retraction of the pushing cylinder 203 and the positioning cylinder 204 are adjusted according to the required number of steel bars to determine the distributing position, dividing the steel bars into two parts. Then the positioning fork 206 is fixed, the linkage baffle plate 1031 is opened, and the distributing fork 205 pushes the steel bars to be processed through the guide frame and slides down to the conveying structure 3.

[0113] The motor 3011 of the conveying structure 3 drives the main drive shaft 3012 to rotate, which in turn drives the drive sprocket 3014 to rotate, thereby causing the conveying chain 3013 to operate. The reinforcing bars move from the conveying chain 3013 of the transverse displacement structure 301 to the longitudinal displacement structure 302 along its specific trajectory. Upon passing the second guide frame 304, they smoothly transition to the longitudinal displacement structure 302 (roller conveyor belt) under its guidance, achieving continuous and stable material conveying. During this process, the blocking slider 3016 controls the dwell time and conveying of the reinforcing bars on the transverse displacement structure 301, ensuring the conveying rhythm and coordinated operation of all devices.

[0114] The measuring device 4 sets the cutting length by adjusting the position of the sliding platform 402 on the slide rail 401. Before the steel bar is conveyed to the cutting device 5, the cylinder drives the baffle 403 to swing down to the conveying path to intercept the steel bar. At this time, the distance from the cutting device 5 to the baffle 403 is the required steel bar length, and the baffle 403 aligns the steel bar. The hydraulic system of the cutting device 5 drives the clamping plate of the pressing part to clamp the steel bar, and then the cutting part cutter cuts the steel bar to complete the processing. The cut steel bar continues to be conveyed outward by the conveying structure 3.
