Description

Technical Field

[0001] This invention relates to the field of rebar cutting technology, and in particular to a rebar processing assembly line system. Background Technology

[0002] Reinforcing bars refer to steel used in reinforced concrete and prestressed reinforced concrete. They are circular in cross-section, and sometimes square with rounded corners. They are generally used in the construction industry, and may be cut to length for use.

[0003] Chinese patent document CN207086795U discloses a rebar cutting device, belonging to the field of construction tools, which solves the technical problem of low rebar cutting efficiency in the prior art. The rebar cutting device provided by this utility model includes a base, a cutting machine, and a locator. The cutting machine includes a motor, and a cutting disc is mounted on the motor's shaft. The motor and the base are movably connected. A fixed cylinder is installed in the base, and positioning holes are spaced apart on the base. The fixed cylinder has connecting holes corresponding to the positioning holes, and the locator connects to the positioning holes and the connecting holes. However, although this device can cut rebar in large quantities, it has the following drawbacks:

[0004] (1) The ends of multiple steel bars are inserted into different fixed cylinders and abut against the positioner in the connection hole. The operation of inserting the ends of the steel bars into the fixed cylinder is complicated, increases the placement time of the steel bars, and makes the overall cutting efficiency of the steel bars slow.

[0005] (2) Positioning is achieved by inserting screws into positioning holes. Each fixed cylinder has a corresponding screw on top. It is very troublesome to place the screws during cutting, which affects the construction efficiency.

[0006] (3) Since the end of the steel bar is inserted into the fixed cylinder, the inner diameter of the fixed cylinder is slightly larger than the outer diameter of the steel bar. When the cutting disc cuts the steel bar, it may cause the steel bar to shake, resulting in an uneven cutting surface and poor cutting quality. It may even cause the cutting disc to break during cutting, which is quite dangerous. Moreover, the efficiency of cutting a large number of steel bars by the cutting disc is low. However, the cutting efficiency can be improved by using a vertical cutting blade, but there may still be a connection at the cut of the steel bar, which will affect the cutting effect.

[0007] (4) After the steel bars are cut, they need to be pulled out one by one from the corresponding fixed cylinder, which is slow; moreover, the temperature of the cut steel bars is high, and the operator may be burned when they are pulled out; and it takes a long time for the cut steel bars to cool down.

[0008] (5) The cut steel bars are not easy to transport, resulting in relatively low work efficiency. Summary of the Invention

[0009] The purpose of this invention is to overcome the shortcomings of existing technologies, such as the low efficiency of cutting steel bars by a cutting disc, the inefficiency of cutting steel bars by a vertical cutting blade, the potential for connection at the cut point of the steel bar affecting the cutting effect, the inconvenience of transporting the cut steel bars, and the relatively low work efficiency. The invention provides a steel bar processing assembly line system.

[0010] In a first aspect, the present invention provides a steel bar processing assembly line system, comprising:

[0011] A first steel bar conveying line is provided along the length of the steel bar processing assembly line.

[0012] A second rebar conveyor line is provided, with its length direction aligned with the rebar processing assembly line. One end of the second rebar conveyor line is adjacent to one end of the first rebar conveyor line. A cutting gap is provided between the second and the first rebar conveyor line. Both the first and second rebar conveyor lines have placement spaces along their length direction for rebars to be cut. The placement spaces on the first and second rebar conveyor lines correspond to each other. The first and second rebar conveyor lines can control the movement of the rebars within the placement spaces along the rebar processing assembly line.

[0013] A cutting device, comprising a lifting bracket and a cutting assembly, the cutting assembly comprising a rebar fixing mechanism and a cutting blade, the lifting bracket holding the cutting blade across the cutting gap with the blade facing downwards, the cutting blade being able to be inserted into the cutting gap, the lifting bracket being able to adjust the height of the cutting blade vertically, and the rebar fixing mechanism being used to fix the rebar to be cut within the placement space.

[0014] This invention provides a rebar processing assembly line system, in which rebar conveyor line one and rebar conveyor line two are arranged adjacent to each other along the rebar processing assembly line, with a cutting gap between them; and rebar conveyor line one and rebar conveyor line two have corresponding placement spaces for rebars to be cut along their length direction, allowing the rebars to be placed in the corresponding placement spaces on rebar conveyor line one and rebar conveyor line two, so that the rebars to be cut cross the cutting gap; and a cutting device is provided at the cutting gap, the cutting components of the cutting device including a rebar fixing mechanism and a cutting blade, the rebar fixing mechanism being able to fix the placement space The cutting device uses a lifting bracket to position the cutting blade across the cutting gap within the space to be cut, with the blade facing downwards. The lifting bracket can adjust the height of the cutting blade up and down, allowing it to insert into the cutting gap and completely sever the steel bar that crosses it. This prevents any connection at the cut, improving cutting quality and efficiency. After cutting, the steel bar can be controlled by steel bar conveyor lines one and two to move along the steel bar processing assembly line, enabling the next cutting. The cut steel bar can be directly transported away, facilitating convenient transport and high processing efficiency.

[0015] Preferably, the lifting bracket includes a first lifting mechanism disposed on both sides of the width direction of the rebar processing production line corresponding to the cutting gap. The upper ends of the first lifting mechanisms on both sides are jointly fixed to the cutting blade, and the first lifting mechanisms on both sides can lift the cutting blade.

[0016] The first lifting mechanism is set on both sides of the width direction of the steel bar processing production line to fix the cutting blade. It is easy to install and reduces the space occupied on the first and second steel bar conveying lines, so that there is more space for the steel bars to be cut, and more steel bars can be cut at the same time, thus improving the cutting efficiency.

[0017] Preferably, the first lifting mechanism includes a mounting bracket, a rotating tube, a drive motor, and a screw.

[0018] The mounting bracket is provided with a corresponding cut gap, and the mounting bracket is fixed to the corresponding side of the rebar conveying line one and / or the rebar conveying line two.

[0019] The first rotating tube is vertically arranged in the axial direction, and the first rotating tube is horizontally rotatably connected to the first mounting bracket.

[0020] The drive motor is used to drive the rotating tube to rotate horizontally.

[0021] The screw and the rotating tube are coaxially arranged, and the lower end of the screw is rotatably connected to the upper end of the rotating tube.

[0022] The upper end of the screw of the first lifting mechanism on both sides is used to fix the cutting blade.

[0023] The upper ends of the screws of the first lifting mechanisms on both sides are used to fix the cutting blade, preventing the screws from rotating. The drive motor drives the rotating tube to rotate horizontally relative to the mounting bracket, causing the rotating tube to rotate relative to the screw. This changes the height of the screw, allowing the cutting blade to be raised or lowered, thus cutting the reinforcing steel in the gaps. Compared to hydraulic lifting, the combination of the drive motor, rotating tube, and screw allows for better transmission and torque control, resulting in more effective steel cutting.

[0024] Preferably, both the first and second rebar conveying lines include a second mounting bracket and a conveying plate fixed on the second mounting bracket. The upper end of the conveying plate has the placement space, which includes multiple semi-circular grooves. The semi-circular grooves are adapted to the rebars to be cut. The multiple semi-circular grooves are spaced apart along the width direction of the rebar processing assembly line, and the length direction of the semi-circular grooves is set along the direction of the rebar processing assembly line.

[0025] The semi-circular grooves of the first and second steel bar conveying lines are respectively set.

[0026] Mounting bracket 2 ensures the stability of the fixed conveyor plate above. Multiple semi-circular grooves are spaced at intervals along the width of the rebar processing line at the upper end of the conveyor plate to form a space for placing the rebars to be cut. Each rebar to be cut is fitted into a semi-circular groove, which can prevent adjacent rebars to be cut from colliding when being cut. Moreover, each rebar to be cut is more stable when placed in a fitted semi-circular groove, which improves the cutting quality and reduces the cutting risk.

[0027] Preferably, a plurality of ball bearings are movably arranged on the inner surface of the semi-circular groove, which facilitates the control of the steel bars in the placement space by the steel bar conveying line one and the steel bar conveying line two to move along the direction of the steel bar processing production line.

[0028] Preferably, the rebar fixing mechanism includes a support plate, a spring telescopic rod, and a clamping plate;

[0029] The support plate is fixedly installed on the front and rear sides of the cutting blade;

[0030] The clamping plate is provided below the support plate;

[0031] The spring telescopic rod is vertically arranged, with its fixed end fixed to the upper side of the support plate. The output end of the spring telescopic rod passes through the support plate and fixes the clamping plate. The output end of the spring telescopic rod can extend and retract vertically relative to its fixed end. The lower side of the clamping plate has a semi-circular groove two that matches the first semi-circular groove. The circular hole formed by the first and second semi-circular grooves is adapted to the steel bar to be cut. When the output end of the spring telescopic rod is in its natural state, the horizontal plane of the highest point of the second semi-circular groove is below the horizontal plane of the lowest point of the cutting blade.

[0032] The support plate, spring telescopic rod, and clamping plate are all mounted on the cutting blade, forming an integral unit. The lifting bracket allows for simultaneous raising and lowering of both the cutting blade and the rebar fixing mechanism, enabling seamless integration of fixing and cutting. This reduces equipment investment and improves the efficiency of fixing and cutting. Furthermore, the support plate, spring telescopic rod, and clamping plate are located on both the front and rear sides of the cutting blade, allowing for better fixing of the rebar crossing the cutting gap from both sides. The lower side of the clamping plate has a second semi-circular groove that matches the first semi-circular groove. The circular hole formed by the first and second semi-circular grooves fits the rebar to be cut, further enhancing the fixing effect.

[0033] When the output end of the spring telescopic rod is in its natural state, the horizontal plane of the highest point of the semi-circular groove two is below the horizontal plane of the lowest point of the cutting blade. This allows the semi-circular groove two to contact the rebar to be cut earlier than the cutting blade. By utilizing the elasticity of the spring telescopic rod to clamp the rebar to be cut before the cutting blade cuts it, it can prevent the sudden application of a large force to clamp the rebar, thereby preventing the rebar from shifting. This improves the accuracy and stability of the rebar fixing, making the cutting process more stable and safer. It also allows for cutting at higher power speeds, improving cutting efficiency.

[0034] Preferably, the lower end of the second rebar conveying line is provided with multiple limiting components. The limiting components are used to restrict the end of the rebar to be cut in the placement space, which can realize the position positioning of the rebar to be cut and facilitate the determination of whether the cutting position of the rebar to be cut is accurate.

[0035] Preferably, the second steel bar conveying line is provided with a plurality of through slots spaced apart along its length, the through slots being vertically through and arranged along the width direction of the second steel bar conveying line;

[0036] The limiting assembly includes a mounting bracket three, a second lifting mechanism, a drive mechanism, and a baffle.

[0037] The mounting brackets three are fixedly provided on both sides of the width direction of the second steel bar conveying line, and the length direction of the mounting brackets three is set along the length direction of the second steel bar conveying line;

[0038] Each of the mounting brackets on each side is provided with the second lifting mechanism at intervals along the length direction corresponding to the through slot;

[0039] A vertical baffle is fixed to the top of the second lifting mechanism on both sides corresponding to the through slot;

[0040] The drive mechanism can drive the second lifting mechanism to control the lifting and lowering of the baffle;

[0041] The baffle can be adapted to be inserted into the through slot.

[0042] The second lifting mechanism is driven by the drive mechanism to control the baffle to rise and pass through the through slot to achieve the positioning of the limiting component. After the baffle is lowered and passes through the through slot by the drive mechanism, it is prevented from blocking the cut steel bars, so that the second steel bar conveyor line can control the steel bars in the placement space to move along the steel bar processing production line and realize transportation.

[0043] Preferably, the second lifting mechanism includes a rotating tube and a screw rod installed internally in the rotating tube. Both the rotating tube and the screw rod are vertically arranged. The rotating tube is rotatably connected to the mounting bracket on the corresponding side. The tops of the screw rods on both sides of the through groove are jointly fixed to the corresponding baffle.

[0044] Preferably, the driving mechanism includes a ratchet corresponding to each of the rotating tubes two. The ratchet is rotatably mounted on the mounting bracket three on the corresponding side. The ratchet includes an outer wheel and an inner wheel, which can be locked together. The outer wheel of the ratchet mounted on the mounting bracket three on the same side is connected by a toothed belt, which is driven by a drive motor two. The inner wheel of the ratchet is connected to the rotating tube two by a conical friction wheel.

[0045] The second drive motor drives the toothed belt, which in turn drives the outer wheels of all the ratchet wheels on the mounting bracket three on the same side to rotate. By controlling the locking between the outer and inner wheels of the corresponding ratchet, the second lifting mechanism corresponding to the ratchet can be controlled to drive the corresponding baffle to rise and fall, thereby controlling the positioning length of the rebar and cutting rebars of different lengths. This control method requires less equipment and has a low cost.

[0046] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0047] 1. This invention provides a rebar processing assembly line system, in which rebar conveyor line one and rebar conveyor line two are arranged adjacent to each other along the rebar processing assembly line, with a cutting gap between them; and rebar conveyor line one and rebar conveyor line two have corresponding placement spaces for rebars to be cut along their length direction, allowing the rebars to be placed in the corresponding placement spaces on rebar conveyor line one and rebar conveyor line two, so that the rebars to be cut cross the cutting gap; and a cutting device is provided at the cutting gap, the cutting components of the cutting device including a rebar fixing mechanism and a cutting blade, the rebar fixing mechanism being able to fix the placed rebars... The cutting device's lifting bracket positions the cutting blade across the cutting gap within the space containing the reinforcing steel. The blade faces downwards. The lifting bracket can adjust the height of the cutting blade to allow it to penetrate the gap and completely sever the reinforcing steel that crosses it. This prevents any connection at the cut, improving cutting quality and efficiency. After cutting, the steel can be controlled by steel conveyor lines one and two to move along the steel processing assembly line, enabling the next cutting. The cut steel can be directly transported, facilitating convenient transport and high processing efficiency.

[0048] 2. This invention provides a steel bar processing production line system. Compared with the hydraulic lifting method, it uses a drive motor, a rotating tube and a screw to cooperate, which can perform transmission and torque control, and can cut steel bars better.

[0049] 3. This invention provides a rebar processing assembly line system. A support plate, spring telescopic rod, and clamping plate are all mounted on the cutting blade, forming an integral unit. A lifting bracket allows for simultaneous raising and lowering of both the cutting blade and the rebar fixing mechanism, enabling seamless integration of fixing and cutting. This reduces equipment investment and improves the efficiency of fixing and cutting. Furthermore, the support plate, spring telescopic rod, and clamping plate are positioned on both the front and rear sides of the cutting blade, allowing for better fixing of the rebar crossing the cutting gap from both sides. A second semi-circular groove, matching the first semi-circular groove, is provided on the lower side of the clamping plate. The circular hole formed by the first and second semi-circular grooves accommodates the rebar to be cut, further enhancing the fixing effect. When cutting reinforcing bars, the semi-circular groove 2 contacts the reinforcing bar earlier than the cutting blade. The elasticity of the spring telescopic rod clamps the reinforcing bar before the cutting blade cuts it, which can prevent the reinforcing bar from being displaced by suddenly applying a large force to clamp it. This improves the accuracy and stability of the reinforcing bar fixing, making the cutting process more stable and safer. It also allows for cutting at higher power speeds, thus improving cutting efficiency.

[0050] 4. This invention provides a steel bar processing production line system. A second drive motor drives a toothed belt, which drives the outer wheels of all ratchets on the same side of the mounting bracket three to rotate. By controlling the locking between the outer and inner wheels of the corresponding ratchet, the second lifting mechanism corresponding to the ratchet can be controlled to drive the corresponding baffle to rise and fall, thereby controlling the positioning length of the steel bar and cutting steel bars of different lengths. Moreover, this control method requires less equipment and has low cost. Attached Figure Description

[0057] The present invention will now be described in further detail with reference to specific embodiments. However, this should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0058] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of the present invention is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the product / equipment / device is typically placed during use.

[0062] Furthermore, in the description of the technical solution of this invention, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0063] Example 1

[0064] like Figure 1 As shown, a steel bar processing assembly line system includes: a steel bar conveying line 1, a steel bar conveying line 2, and a cutting device.

[0065] In this embodiment, the length direction of the rebar conveying line 1 is arranged along the rebar processing assembly line; the rebar processing assembly line direction can be referenced. Figure 1 From the lower left corner to the upper right corner. The length direction of the second rebar conveyor line 2 is set along the direction of the rebar processing assembly line. One end of the second rebar conveyor line 2 is adjacent to one end of the first rebar conveyor line 1. A cutting gap is provided between the second rebar conveyor line 2 and the first rebar conveyor line 1. The first rebar conveyor line 1 and the second rebar conveyor line 2 are provided with a placement space for the rebar to be cut along the length direction. The placement spaces on the first rebar conveyor line 1 and the second rebar conveyor line 2 correspond to each other. The first rebar conveyor line 1 and the second rebar conveyor line 2 can control the movement of the rebar in the placement space along the direction of the rebar processing assembly line.

[0066] In optional implementations, such as Figure 2 and Figure 3 As shown, both the first rebar conveying line 1 and the second rebar conveying line 2 include a second mounting bracket 11 and a conveying plate 12 fixed on the second mounting bracket 11. The second mounting bracket 11 can ensure the stability of the conveying plate 12 fixed above it. Figure 2 and Figure 3 As shown, the mounting bracket 2 11 adopts a table-type structure, placed on a flat surface, which also ensures the stability of the conveyor plate 12 fixed above. The upper end of the conveyor plate 12 has a placement space, which includes multiple semi-circular grooves 13. Each semi-circular groove 13 is adapted to the rebar to be cut, so that each rebar to be cut is fitted into one semi-circular groove 13. This avoids collisions between adjacent rebars to be cut within the placement space during cutting, and each rebar to be cut is more stable when placed in its fitted semi-circular groove 13, improving cutting quality and reducing cutting risks. The multiple semi-circular grooves 13 are arranged at intervals along the width direction of the rebar processing production line, and the length direction of the semi-circular grooves 13 is set along the direction of the rebar processing production line. The semi-circular grooves 13 of rebar conveyor line 1 and rebar conveyor line 2 are correspondingly arranged, allowing multiple rebars to be cut to be placed in the width direction of rebar conveyor line 1 and rebar conveyor line 2, enabling batch cutting operations.

[0067] The reinforcing bars are placed in the semi-circular groove 13, which is more efficient than the prior art where the ends of the reinforcing bars are inserted into the fixed cylinder. After the reinforcing bars are placed in the semi-circular groove 13, the reinforcing bar conveying line 1 and the reinforcing bar conveying line 2 transport the reinforcing bars. Existing transmission components are used for transporting the reinforcing bars, and it is only necessary to ensure stable transmission. This embodiment will not be described in detail.

[0068] Furthermore, multiple ball bearings 14 are movably disposed on the inner surface of the semi-circular groove 13. These ball bearings 14 are existing technology and can reduce friction between the semi-circular groove 13 and the reinforcing bar, facilitating the movement of the reinforcing bar within the placement space along the reinforcing bar processing assembly line by the reinforcing bar conveyor line 1 and the reinforcing bar conveyor line 2, making the reinforcing bar transport smoother. The ball bearings are rotatably connected within the placement space, i.e., rotatably connected within the semi-circular groove 13, with their pivot position remaining stationary. This assists in the movement of the reinforcing bar along the reinforcing bar processing assembly line while preventing the ball bearings 14 from slipping off the end of the semi-circular groove 13.

[0069] In this embodiment, the cutting device includes a lifting bracket and a cutting assembly 6. The cutting assembly 6 includes a rebar fixing mechanism and a cutting blade 62. The lifting bracket holds the cutting blade 62 above the cutting gap. The cutting blade 62 has its blade facing downwards and can be inserted into the cutting gap. The lifting bracket can adjust the height of the cutting blade 62 up and down. The rebar fixing mechanism is used to fix the rebar to be cut in the placement space.

[0070] In an optional embodiment, the lifting bracket includes a first lifting mechanism disposed on both sides of the width direction of the rebar processing assembly line corresponding to the cutting gap. The upper ends of the first lifting mechanisms on both sides are jointly fixed to the cutting blade 62. The first lifting mechanisms on both sides can lift the cutting blade 62. The first lifting mechanism disposed on both sides of the width direction of the rebar processing assembly line to jointly fix the cutting blade 62 is easy to install and reduces the space occupied on the rebar conveying line 1 and the rebar conveying line 2, so that there is more space for placing the rebar to be cut, and more rebar can be cut at the same time, thereby improving the cutting efficiency.

[0071] In optional implementations, such as Figure 2 As shown, the first lifting mechanism includes a mounting bracket 3, a rotating tube 4, a drive motor 5, and a screw 61;

[0072] The mounting bracket 3 is configured to correspond to the cut gap, and the mounting bracket 3 is fixed to the corresponding side of the rebar conveying line 1 and / or the rebar conveying line 2; in a preferred embodiment, the mounting bracket 3 is fixed to the corresponding side of the rebar conveying line 1 and the rebar conveying line 2, such as... Figure 2 In the process, two mounting brackets 1 and 3 are set up, located on both sides of the width direction of the steel bar processing production line. The mounting bracket 1 and 3 on the left side are fixed to the left side of the steel bar conveying line 1 and the steel bar conveying line 2, and the mounting bracket 1 and 3 on the right side are fixed to the right side of the steel bar conveying line 1 and the steel bar conveying line 2.

[0073] Each mounting bracket 3 corresponds to a rotating tube 4, a screw 61, and a drive motor 5. The rotating tube 4 is vertically oriented and horizontally rotatably connected to the mounting bracket 3. The drive motor 5 is fixed to the mounting bracket 3, and its output shaft is fixedly connected to the rotating tube 4, allowing the drive motor 5 to drive the rotating tube 4 to rotate horizontally when it is working. The screw 61 is coaxially arranged with the rotating tube 4, and its lower end is rotatably connected to the upper end of the rotating tube 4. The upper ends of the screws 61 of the first lifting mechanisms on both sides are used to fix the cutting blade 62, preventing the screw 61 from rotating. The drive motor 5 drives the rotating tube 4 to rotate horizontally relative to the mounting bracket 3, causing the rotating tube 4 to rotate relative to the screw 61, thereby changing the height of the screw 61 and allowing the cutting blade 62 to be raised and lowered to cut the reinforcing steel in the cutting gap. Compared to hydraulic lifting, the combination of drive motor 5, rotating tube 4 and screw 61 enables transmission and torque control, resulting in better cutting of steel bars.

[0074] Specifically, there are two screws 61, which are threadedly connected to two rotating tubes 4 respectively. A cutting blade 62 is fixed to the upper end of both screws 61. Since the cutting blade 62 is fixedly connected to the screws 61 and the two screws 61 are threadedly installed in the rotating tubes 4 respectively, the cutting blade 62 moves up and down when the rotating tubes 4 rotate. The cutting blade 62 is located in the cutting gap between the rebar conveying line 1 and the rebar conveying line 2. When the cutting blade 62 moves downward, it can cut the rebar to be cut, and the cutting blade 62 will be inserted into the cutting gap so that the rebar processing assembly line system can complete the cutting of the rebar and prevent the rebar from still having a connection at the cut, which would affect the cutting effect.

[0075] In optional implementations, such as Figure 2 As shown, the rebar fixing mechanism includes a support plate 63, a spring telescopic rod 64, and a clamping plate 65; the number of clamping plates 65 is the same as the number of support plates 63 and they are correspondingly arranged.

[0076] The support plate 63 is fixedly mounted on both the front and rear sides of the cutting blade 62; the clamping plate 65 is disposed below the support plate 63; the spring telescopic rod 64 is vertically arranged, with its fixed end fixed to the upper side of the support plate 63 and its output end passing through the support plate 63 to fix the clamping plate 65. The support plate 63, spring telescopic rod 64, and clamping plate 65 are all mounted on the cutting blade 62, forming an integral unit with it. The lifting bracket allows for simultaneous lifting and lowering of both the cutting blade 62 and the rebar fixing mechanism, enabling seamless integration of fixing and cutting, reducing equipment investment, and improving the efficiency of fixing and cutting. Furthermore, the fact that the support plate 63, spring telescopic rod 64, and clamping plate 65 are all mounted on both the front and rear sides of the cutting blade 62 allows for better fixing of the rebar crossing the cutting gap from both sides of the gap.

[0077] The output end of the spring telescopic rod 64 can extend and retract vertically relative to the fixed end of the spring telescopic rod 64. The lower side of the clamping plate 65 is provided with a semi-circular groove 66 that matches the semi-circular groove 13. The circular hole formed by the semi-circular groove 13 and the semi-circular groove 66 is adapted to the steel bar to be cut, so that the fixing effect of the steel bar to be cut is better.

[0078] Using the above-mentioned rebar fixing mechanism, when the first lifting mechanism drives the cutting blade 62 to descend, the output end of the spring telescopic rod 64 is in its natural state. Since the horizontal plane of the highest point of the semi-circular groove 66 is below the horizontal plane of the lowest point of the cutting blade 62, the semi-circular groove 66 contacts the rebar to be cut earlier than the cutting blade 62. Due to the design of the spring telescopic rod 64, when the semi-circular groove 66 contacts the rebar and the cutting blade 62 continues to move downward, the output end of the spring telescopic rod 64 will contract due to its elastic design. The spring telescopic rod 64 uses its own elastic force to clamp the rebar with the semi-circular groove 66. At this time, the cutting blade 62 will cut the rebar. After the spring telescopic rod 64 is compressed to its shortest state, the downward pressure of the cutting blade 62 makes the semi-circular groove 66 cooperate with the semi-circular groove 13 to clamp the rebar again. This also prevents the rebar processing production line system from suddenly applying a large force to clamp the rebar, thereby causing the rebar to shift, making the device more stable.

[0079] The output end of the spring telescopic rod 64 retracts vertically, generating a reverse elastic force that acts on the clamping plate 65. This causes the semi-circular grooves 66 at the bottom of the clamping plates 65 on both sides of the cutting blade 62 to continuously clamp the reinforcing bar to be cut with the semi-circular grooves 13 of the reinforcing bar conveying lines 1 and 2, respectively. This ensures the stable fixation of the reinforcing bar during cutting, preventing it from shaking. Meanwhile, the cutting blade 62 continuously descends into the cutting gap, completely severing the reinforcing bar. This method of using the elastic force of the spring telescopic rod to clamp the reinforcing bar before it is cut by the cutting blade prevents the sudden application of a large force to clamp the reinforcing bar, thus preventing displacement. It improves the accuracy and stability of the reinforcing bar fixation, making the cutting process more stable and safer. This allows for higher power cutting speeds, increasing cutting efficiency, and resulting in a smooth cutting surface and high cutting quality.

[0080] In an optional embodiment, the lower end of the rebar conveying line 2 is provided with a plurality of limiting components 7. The limiting components 7 are used to restrict the ends of the rebar to be cut in the placement space, which can realize the position positioning of the rebar to be cut and facilitate the determination of whether the cutting position of the rebar to be cut is accurate.

[0081] The rebar processing assembly line system described in this embodiment is characterized by rebar conveyor line 1 and rebar conveyor line 2 being arranged adjacently along the rebar processing assembly line, with a cutting gap between them. Both rebar conveyor lines 1 and 2 have corresponding placement spaces along their length for the rebars to be cut, allowing the rebars to be placed within these spaces and cross the cutting gap. A cutting device is installed at the cutting gap, and the cutting component 6 of the cutting device includes a rebar fixing mechanism and a cutting blade 62. The rebar fixing mechanism can fix the placement space... The cutting device's lifting bracket positions the cutting blade 62 across the cutting gap within the space to be cut, with the blade facing downwards. The lifting bracket can adjust the height of the cutting blade 62 vertically, allowing it to insert into the gap and completely sever the steel bar crossing it. This prevents any connection at the cut, improving cutting quality and efficiency. After cutting, the steel bar can be controlled to move along the steel bar processing assembly line via steel bar conveyor lines 1 and 2, enabling subsequent cutting. The cut steel bars can be directly transported, facilitating convenient transport and high processing efficiency. The movement of steel bar conveyor lines 1 and 2 along the steel bar processing assembly line can be achieved using conventional conveyor belts or hydraulic pushers. The steel bar fixing mechanism uses the elasticity of a spring-loaded telescopic rod to clamp the steel bar, preventing sudden large forces from causing displacement and ensuring more stable steel bar cutting. The design of the semi-circular groove 13 and the limiting component enables the rebar processing assembly line system to cut rebars of the same length in large batches during use, improving the working efficiency of the device. Furthermore, the rebars can continue to be transported after cutting, further improving the working efficiency of the rebar processing assembly line system.

[0082] The specific implementation of this embodiment is as follows: When using the rebar processing assembly line system, the rebar to be cut is placed in the semi-circular groove 13. Then, the limiting component 7 is adjusted according to the required length of the rebar. The rebar is transported using the rebar transmission components of rebar conveying line 1 and rebar conveying line 2. After the rebar is transported to the position limited by the limiting component 7, the drive motor 5 is started. When the drive motor 5 is working, it will drive the rotating tube 4 to rotate. The rotating tube 4 is connected to the screw 61 by a thread, which allows the screw 61 to move downward, thereby allowing the cutting blade 62 to move downward. Then, the semi-circular groove 66 will first contact the rebar, and then the output end of the spring telescopic rod 64 will retract. During the retraction of the spring telescopic rod 64, the cutting blade 62 cuts the rebar. After the cutting is completed, the drive motor 5 is controlled to rotate in the opposite direction, so that the cutting blade 62 moves back to the initial position.

[0083] Example 2

[0084] This embodiment provides a rebar processing assembly line system. Based on embodiment 1, the structure of the limiting component 7 has been further optimized, enabling the rebar processing assembly line system to cut rebars of different sizes in large quantities during use.

[0085] like Figure 3 As shown, the second steel bar conveying line 2 is provided with a plurality of through slots 75 spaced apart along its length direction. The through slots 75 are vertically through and are arranged along the width direction of the second steel bar conveying line 2.

[0086] The limiting component 7 includes a mounting bracket 3 71, a second lifting mechanism, a driving mechanism, and a baffle 74; the mounting bracket 3 71 is fixedly provided on both sides of the width direction of the rebar conveying line 2, and the length direction of the mounting bracket 3 71 is set along the length direction of the rebar conveying line 2; and the mounting bracket 3 71 on the left and right sides are connected to form a mounting bracket, making the structure more stable.

[0087] Mounting bracket 3 71 is fixed to the lower end of rebar conveying line 2. Each side of mounting bracket 3 71 is provided with a second lifting mechanism at intervals along its length corresponding to the through groove 75. A vertical baffle 74 is fixed to the top of the second lifting mechanisms on both sides corresponding to the through groove 75. The driving mechanism can drive the second lifting mechanism to control the lifting and lowering of the baffle 74. The baffle 74 can be inserted into the through groove 75. The positioning of the limiting component 7 is achieved by driving the second lifting mechanism to raise the baffle 74 through the through groove 75, which can directly position a batch of rebars. Compared with the existing technology of inserting corresponding screws above each fixed cylinder, its positioning efficiency is high. After the baffle 74 is lowered through the through groove 75 by the driving mechanism, it avoids blocking the cut rebars, allowing the rebar conveying line 2 to control the rebars in the placement space to move along the rebar processing production line for transportation.

[0088] In optional implementations, such as Figure 3As shown, the second lifting mechanism includes a second rotating tube 72 and a second screw 73 threadedly installed inside the second rotating tube 72. Both the second rotating tube 72 and the second screw 73 are vertically arranged. The second rotating tube 72 is rotatably connected to the third mounting bracket 71 on the corresponding side. The tops of the second screws 73 on both sides of the through groove 75 are jointly fixed to the corresponding baffle 74. That is, by synchronously rotating the second rotating tubes 72 on the left and right sides, the second rotating tubes 72 on the left and right sides rotate relative to the third mounting bracket 71 on the corresponding side. The tops of the second screws 73 on the left and right sides are jointly fixed to the corresponding baffle 74, so that the second screws 73 cannot rotate. However, the second screws 73 are threadedly installed inside the corresponding second rotating tube 72, so that the second rotating tube 72 and the second screw 73 will rotate relative to each other, thereby changing the length of the second screw 73 inside the second rotating tube 72, realizing the lifting and lowering of the baffle 74.

[0089] Furthermore, such as Figure 4 and Figure 5 As shown, the driving mechanism includes a ratchet 76 corresponding to each of the rotating tubes 72. The ratchet 76 is rotatably mounted on the corresponding mounting bracket 71. Each ratchet 76 includes an outer wheel and an inner wheel, which can be locked together. The outer wheel of the ratchet 76 mounted on the same mounting bracket 71 is connected by a toothed belt 77, which is driven by a drive motor 79. The inner wheel of the ratchet 76 is connected to the rotating tube 72 via a conical friction wheel 78. When the ratchet 76 is locked, the inner wheel rotates simultaneously with the outer wheel. When the ratchet 76 is not locked, the outer wheel does not drive the inner wheel to rotate. The ratchet 76 is existing technology and will not be described in detail in this embodiment.

[0090] The lower end of the rebar conveying line 2 is designed with two drive motors 2 79 for driving the toothed belt 77. The output end of the drive motor 2 79 is fixed with a gear, which meshes with the toothed belt 77. When the gear rotates, it can transmit power to the toothed belt 77, thereby driving the outer wheels of all ratchet 76 on the mounting bracket 3 71 on the same side to rotate. By controlling the locking between the outer wheel and the inner wheel of the corresponding ratchet 76, the second lifting mechanism corresponding to the ratchet 76 can be controlled to drive the corresponding baffle 74 to rise and fall, thereby controlling the positioning length of the rebar to be cut, so that rebar of different lengths can be cut. Moreover, this control method requires less equipment and has low cost.

[0091] The specific implementation of this embodiment is as follows: When using the rebar processing assembly line system, firstly, the ratchet 76 to be used is locked according to the required length of rebar to be cut. Then, the drive motor 79 is controlled to rotate. When the drive motor 79 rotates, the copper tube toothed belt 77 causes the corresponding ratchet 76 to rotate. The ratchet 76 drives the rotating tube 72 to rotate through the conical friction wheel 78. The rotating tube 72 causes the baffle 74 to move upward through the threaded connection between it and the screw 73. The baffle 74 can block the transmission of rebar, thereby playing a limiting role. After the rebar is cut, the drive motor 79 is controlled to reverse, thereby causing the baffle 74 to move downward. When the rebar is being transmitted, the cut rebar can be pushed down. There is no need for manual picking up of the rebar or pulling the rebar out of the corresponding fixed cylinder one by one. The operation speed is fast and the work efficiency is improved.

[0092] It should be noted that the specific installation methods, circuit connection methods, and control methods of the rebar conveying line 1, rebar conveying line 2, drive motor, etc. in this invention are all conventional designs, and will not be described in detail in this invention.

[0093] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
