Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, and in particular to a steel bar bending device for construction engineering. Background Art

[0002] Engineering construction refers to the construction, expansion and reconstruction of construction projects, such as construction projects, line pipeline and equipment installation projects, and building decoration and renovation projects. A large amount of building materials will be used in the process of engineering construction. Steel bars are very important building materials. In the process of construction, bent steel bars are widely used in stirrups, positioning bars, ear bars, etc. According to construction needs, it is often necessary to bend a fixed point of the steel bar at a certain angle. Therefore, bending equipment is needed in the processing of steel bars. However, it is not easy to adjust the bending according to the volume of the steel bar when bending the steel bar, which affects the force of the equipment during bending, resulting in incomplete bending of the steel bar by the equipment, thereby increasing the difficulty of bending the steel bar and reducing the efficiency of bending the steel bar. It is not easy to control the bending force of the steel bar as needed during the bending process, resulting in easy jamming during the bending process of the steel bar. In addition, the steel bar is prone to deformation during the bending process, which can cause damage to the staff, affecting the staff's feeding of the steel bar.

[0003] In summary, it is not easy to adjust the bending according to the volume of the steel bars when bending, which affects the force applied to the equipment during bending, resulting in incomplete bending of the steel bars by the equipment, reducing the efficiency of the steel bar bending. It is not easy to control the strength of the steel bar bending as needed during the bending process. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention solves the technical problems by adopting the following technical solutions: a steel bar bending device for construction engineering construction according to the present invention comprises a base, a bending cylinder is fixedly connected to the bottom of the inner cavity of the base, and further comprises:

[0005] A connecting plate, which is slidably connected to the inner surface of the base and extends to the outside of the base through the top of the connecting plate. A moving block is fixedly connected to the outer surface of the connecting plate and extends to the inside of the base through the bottom of the moving block. A side of the moving block away from the connecting plate is fixedly connected to a mounting frame and extends to the inside of the base through the bottom of the mounting frame. A bending block is fixedly connected to the inner surface of the mounting frame;

[0006] A fixing component, which is fixedly connected to the top of the base, and is used to fix the steel bars to be bent. Two fixing components are arranged on the base. A protective component is fixedly connected to the position of the base away from the fixing component, and a feeding component is fixedly connected to the position of the base close to the protective component, and the feeding component is between the protective component and the fixing component;

[0007] The fixing assembly includes a fixing seat, which is fixedly connected to the top of the base, a pressing shell is fixedly connected to the top of the fixing seat, and a booster plate is fixedly connected to the outer surface of the pressing shell, and the booster plate is fixedly connected to the fixing seat at a position close to the pressing shell;

[0008] A rotating column, which is fixedly connected to the inner surface of the fixed seat, and is used to adjust the fixation of the steel bars. An extrusion frame is fixedly connected to the outer surface of the rotating column, and the extrusion frame extends to the outside of the fixed seat through a position away from the rotating column. A reinforcement plate is fixedly connected to the bottom of the extrusion frame, and is slidably connected to the fixed seat through the bottom of the reinforcement plate. A movable block is fixedly connected to the side of the reinforcement plate away from the extrusion frame.

[0009] The rotating column and the movable block are fixed by the fixed seat. As the pressing shell contracts under the pressure, the lifting column is pushed down, and the reset plate contracts under the pressure of the pressing shell. The reset plate stops moving when it contracts to contact the limiting frame. The lifting column descends and drives the fixed column to move, so that the fixed column drives the external plate to squeeze the reinforcement plate. The reinforcement plate is under pressure to drive the movable block to rotate inside the fixed seat. The reinforcement plate applies thrust to the extrusion frame as the movable block rotates, so that the extrusion frame drives the rotating column to rotate with a booster plate. The booster plate cooperates with the reinforcement plate on the fixed seat to press the extrusion frame to bend and clamp the steel bar. Then the bending cylinder contracts and drives the connecting plate to move on the base in the direction close to the steel bar. When the connecting plate moves, the installing frame is driven to move via the moving block, so that the bending block inside the installing frame moves to contact the steel bar for bending. The bending cylinder extends after the steel bar is bent, so that the bending cylinder drives the moving block away from the steel bar through the connecting plate, and the installing frame drives the bending block to move with the moving block. After the steel bar is bent, the pressing shell is released, so that the reset plate is reset and pushes the pressing shell to rise. The pressing shell rises and drives the fixed column to move via the lifting column, so that the external plate moves with the fixed column and separates from the reinforcement plate. When the reinforcement plate loses the pressure of the external plate, the movable block rotates and resets to stretch the reinforcement plate, so that the extrusion frame loses the thrust of the reinforcement plate and releases the steel bar, thereby taking out the bent steel bar.

[0010] Preferably, the outer surface of the movable block is rotatably connected to the fixed seat, and the top of the extrusion frame is fixedly connected to the boosting plate.

[0011] Preferably, a side of the connecting plate close to the moving block is fixedly connected to the bending cylinder, and an outer surface of the moving block is fixedly connected to the base.

[0015] Preferably, the bottom end of the lifting column passes through the pressing shell, and the bottom of the external plate is slidably connected to the reinforcement plate.

[0016] Preferably, the protection assembly includes a placement seat, which is fixedly connected to the top of the base, and the placement seat is used to place the steel bars. The outer surface of the placement seat is slidably connected to an adjustment rod, and two adjustment rods are arranged on the placement seat, and one end of the adjustment rod close to the placement seat is fixedly connected to a limiting plate;

[0017] A guide seat is fixedly connected to the top of the base, and is used to guide the movement of the steel bars. The top of the guide seat is fixedly connected to a support plate, the top of the support plate is fixedly connected to a lifting cylinder, and the bottom of the lifting cylinder is fixedly connected to a knocking block.

[0018] Preferably, the side of the guide seat close to the limiting plate is fixedly connected to the placement seat, and the point of the lifting cylinder passes through the support plate.

[0019] Preferably, the inner surface of the guide seat is fixedly connected to a protective ring, the outer surface of the protective ring is fixedly connected to an inner support plate, which is distributed in a circle on the protective ring through the inner support plate, the protective ring is fixedly connected to a buffer frame at a position away from the inner support plate, the inner surface of the protective ring is rotatably connected to a movable ball, multiple movable balls are arranged on the protective ring, and the protective ring is fixedly connected to an internal plate at a position away from the movable ball.

[0020] Preferably, the side of the inner support plate away from the protective ring is fixedly connected to the guide seat, and the side of the buffer frame away from the protective ring is fixedly connected to the guide seat.

[0021] Preferably, the feeding assembly includes an assembly plate, which is fixedly connected to the top of the base, and is located between the guide seat and the fixed seat through the assembly plate. The inner surface of the assembly plate is rotatably connected to a screw rod, and one end of the screw rod is fixedly connected to a motor. The position of the motor near the screw rod is fixedly connected to the assembly plate, and the outer surface of the screw rod is rotatably connected to a displacement block.

[0022] A connecting frame is fixedly connected to the bottom of the displacement block, the top of the inner cavity of the connecting frame is rotatably connected to a feed roller frame, and a telescopic rod is fixedly connected to the side of the connecting frame close to the assembly plate. Two telescopic rods are arranged on the assembly plate, and the outer surface of the telescopic rod is fixedly connected to the assembly plate.

[0023] The steel bar passes through the guide seat and the assembly plate, and the motor drives the screw on the assembly plate to rotate clockwise, so that the screw drives the two displacement blocks to approach each other, and the displacement blocks drive the connecting frame to move. When the feeding roller frame on the connecting frame contacts the steel bar, it stops, and the feeding roller frame moves to transport the steel bar. When the connecting frame moves, the telescopic rod is extended, and the screw rotates counterclockwise to drive the two displacement blocks away from each other, so that the connecting frame drives the feeding roller frame away from the steel bar, and at the same time, the connecting frame pushes the telescopic rod to shrink.

[0024] The present invention provides a steel bar bending device for construction engineering. It has the following beneficial effects:

[0025] 1. The steel bar bending device for construction engineering is provided with an installation frame, a bending block, a bending cylinder and a fixed component. The installation frame drives the bending block to move when the moving block moves, so that the bending block performs bending work when it contacts the steel bar, and the installation frame can protect the bending block when it moves along the base to prevent the bending block from loosening on the installation frame. Two fixed components are arranged on the base, so that the fixed component can fix the steel bar, and the bending block can tighten the steel bar after the steel bar is clamped on the fixed component to ensure the bending force of the steel bar on the fixed component and prevent the steel bar from being incompletely bent. The protective component can pre-process the feeding of the steel bar on the base to ensure the stability of the steel bar when it is fixed.

[0026] 2. The steel bar bending device for construction engineering is fixed on the base through a fixed seat, which is convenient for the connection between the fixed seat and the base to maintain the force of the steel bar during bending and ensure the accuracy of the steel bar bending. The movable block is driven by the reinforcement plate to rotate inside the fixed seat to ensure that the reinforcement plate can be fully stressed to move. The movable block is reset when the reinforcement plate loses pressure, so that the reinforcement plate stops pushing the extrusion frame, thereby loosening the fixation of the extrusion frame.

[0027] 3. The steel bar bending device for construction engineering pushes the extrusion frame to move through the pressure exerted by the descending pressing shell on the reinforcement plate, so that the reinforcement plate supports the extrusion frame to increase the clamping force, prevents the steel bars from falling off during bending and affecting the bending of the steel bars. When the extrusion frame is subjected to thrust, it drives the rotating column to rotate on the fixed seat, so that the rotation of the rotating column transfers the pressure on the extrusion frame to the booster plate, avoiding the problem of improper placement of the steel bars when they are connected and fixed.

[0028] 4. The steel bar bending device for construction engineering uses pressure on the pressing shell on the fixed seat to squeeze the reset plate and the lifting column, so that the pressing shell contracts to push the lifting column down, thereby using the contraction of the pressing shell to apply pressure, and the limiting frame is inside the reset plate, so that the limiting frame can limit the contraction range of the reset plate. When the top of the limiting frame contacts the reset plate, the limiting frame presses the pressing shell through the reset plate, thereby increasing the bearing capacity of the pressing shell itself and limiting the contraction range of the pressing shell.

[0029] 5. The steel bar bending device used in construction engineering drives the fixed column to move by lifting the lifting column, so that the lifting column can locate the installation position of the pressing shell, prevent the displacement of the pressing shell from affecting the movement of the lifting column, and thus ensure the vertical lifting movement of the lifting column and the fixed column. The external plate is distributed in a circular shape on the fixed column, which is convenient for the external plate to descend to contact the reinforcement plate, preventing the movement of the reinforcement plate inside the pressing shell from being affected, thereby ensuring the stability of the reinforcement plate when pushing the extrusion frame to move.

[0030] 6. The steel bar bending device used in construction engineering projects places steel bars on the base through a placing seat, which facilitates the loading movement of the steel bars along the placing seat, thereby improving the firmness of the steel bars. The placing seat and the guide seat cooperate to protect the steel bars. The adjusting rod moves on the placing seat under the thrust, so that the adjusting rod pushes the limiting plates to contact the steel bars, making it easier for the limiting plates to limit the position of the steel bars, thereby avoiding the movement of the steel bars during transportation.

[0031] 7. The steel bar bending device used in the construction project fixes the lifting cylinder on the guide seat through the support plate, which is convenient for the support plate to protect the lifting cylinder and prevent the lifting cylinder from loosening or falling off on the support plate. The knocking block is driven by the lifting cylinder to move up and down, so that the knocking block repeatedly knocks on the steel bar, which is convenient for correcting the bending position of the steel bar by knocking, avoiding the situation where the steel bar is bent and caused to jam during transportation.

[0032] 8. The steel bar bending device used in construction projects guides the steel bars after being hammered through a guide seat, so that the guide seat and the protective ring cooperate to protect the transportation, avoiding the steel bars from moving around and causing bending during transportation. The inner support plates are distributed in a circle on the protective ring, so that the inner support plates are connected to the guide seat to fix the protective ring, thereby reinforcing the installation position of the protective ring, avoiding the protective ring from loosening inside the guide seat to affect the movement of the steel bars, and facilitating sharing of pressure.

[0033] 9. The steel bar bending device used in construction projects contacts the guide seat on the protective ring through the buffer frame, so that the buffer frame protects the protective ring and guides the placement of the steel bars at the same time, avoiding excessive wear and tear of the steel bars when moving inside the guide seat, and the movable ball and the buffer frame cooperate with each other to guide the placement of the steel bars, avoiding the steel bars moving around and colliding inside the guide seat, making it difficult for the movable ball to separate from the protective ring during movement, ensuring the convenience of the movable ball movement, thereby ensuring the movable space for the steel bars inside the protective ring.

[0034] 10. The steel bar bending device used in construction engineering projects corresponds to the guide seat through the assembly plate, so that the assembly plate can limit the movement of the steel bar, thereby utilizing the installation position of the assembly plate to limit the position of the steel bar leaving the guide seat. The connecting frame is driven by the displacement block to move, so that the connecting frame drives the feeding roller frame to contact the steel bar, making it easier for the feeding roller frame to limit the steel bar, and as the feeding roller frame rotates, the contacted pipe rack is transported, thereby utilizing the rotation of the feeding roller frame to achieve the effect of automatic loading.

The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0049] Example 1, please refer to Figure 1-Figure 12 The present invention provides a technical solution: a steel bar bending device for construction engineering, comprising a base 1, a bending cylinder 9 is fixedly connected to the bottom of the inner cavity of the base 1, and the bending cylinder 9 is extended and retracted on the base 1 to drive the moving block 2 to reciprocate in the horizontal direction through the connecting plate 8, so that the moving block 2 moves to adjust the bending position, and as the connecting plate 8 and the moving block 2 move along the base 1, it is not easy to deviate during movement, resulting in insufficient force on the steel bar, ensuring the accuracy of subsequent steel bar bending, and the extension and retraction of the bending cylinder 9 controls the movement of the moving block 2, and also includes:

[0050] A connecting plate 8 is slidably connected to the inner surface of the base 1, and a moving block 2 is fixedly connected to the outer surface of the connecting plate 8. A mounting frame 3 is fixedly connected to the side of the moving block 2 away from the connecting plate 8. The mounting frame 3 drives the bending block 7 to move when the moving block 2 moves, so that the bending block 7 performs bending work when it contacts the steel bar, and the mounting frame 3 can protect the bending block 7 when it moves along the base 1 to prevent the bending block 7 from loosening on the mounting frame 3, and the mounting frame 3 and the moving block 2 support each other, so that the connection position is not easy to separate and affect the fixation, so that the bending block 7 reinforces the mounting frame 3, thereby increasing the bearing capacity of the mounting frame 3 itself, and the inner surface of the mounting frame 3 is fixedly connected with the bending block 7;

[0051] A fixing component 4 is fixedly connected to the top of the base 1. The fixing component 4 is used to fix the steel bar to be bent. Two fixing components 4 are set on the base 1, so that the fixing component 4 can fix the steel bar. After the steel bar is clamped on the fixing component 4, the bending block 7 tightens the steel bar to ensure the bending strength of the steel bar on the fixing component 4 and prevent the steel bar from being incompletely bent during bending. The two fixing components 4 are arranged horizontally, so that the steel bar fixed by the fixing component 4 is not easy to tilt, which is convenient for the steel bar to fully contact the bending block 7 on the fixing component 4 for bending work. The base 1 is fixedly connected with a protective component 5 at a position away from the fixing component 4. The protective component 5 can be used to pre-process the loading of the steel bar on the base 1, so that the steel bar is not easy to get stuck when moving inside the protective component 5, ensuring the transportation of the steel bar The protection component 5 and the feeding component 6 can cooperate with each other to make the steel bar move in a straight line when it moves. The protection component 5, the feeding component 6 and the fixing component 4 can be adjusted according to the volume of the steel bar, so that the strength of fixing the steel bar can be adjusted according to the needs to ensure the stability of the steel bar when it is fixed. The base 1 is fixedly connected with the feeding component 6 near the protection component 5. The feeding component 6 is between the protection component 5 and the fixing component 4, so that the feeding component 6 can automatically load the steel bar, and the feeding component 6 can play an auxiliary fixing effect when transporting the steel bar, thereby improving the stability of the steel bar during transportation, ensuring that the steel bar slips during transportation and causes the bending position of the steel bar to change. The feeding component 6 can transport the steel bar guided by the protection component 5, so that the steel bar is not prone to jamming during transportation;

[0052] The fixing assembly 4 includes a fixing seat 41, which is fixedly connected to the top of the base 1 and fixed to the base 1 by the fixing seat 41, so that the fixing seat 41 is not easily displaced by the thrust when the steel bar is bent, which is convenient for the connection between the fixing seat 41 and the base 1 to maintain the force of the steel bar when it is bent, and the installation position of the fixing seat 41 corresponds to the bending block 7, so that the bending block 7 moves toward the fixing seat 41 to adjust the force of the steel bar bending, thereby ensuring the accuracy of the steel bar bending, and the top of the fixing seat 41 is fixedly connected with a pressing shell 45, and the outer surface of the pressing shell 45 is fixedly connected with a booster plate 44;

[0053] The rotating column 42 is fixedly connected to the inner surface of the fixing seat 41. The rotating column 42 is used to adjust the fixation of the steel bar. The outer surface of the rotating column 42 is fixedly connected to the extrusion frame 43. When the extrusion frame 43 is subjected to thrust, the rotating column 42 is driven to rotate on the fixing seat 41, so that the pressure exerted on the extrusion frame 43 is transmitted to the boosting plate 44 by the rotation of the rotating column 42, so that the boosting plate 44 can press the extrusion frame 43 tightly, so that the boosting plate 44 and the reinforcing plate 47 cooperate with each other to press the extrusion frame 43 tightly, and prevent the extrusion frame 43 from being subjected to excessive pressure and affecting its use. The rotating column 42 can fix the extrusion frame 43 inside the fixing seat 41, so that the extrusion frame 43 and the feeding assembly 6 can receive the steel bar, and the problem of improper placement when the steel bar is received and fixed is avoided. The bottom of the extrusion frame 43 is fixedly connected to the reinforcing plate 47, and the pressure exerted by the pressing shell 45 on the reinforcing plate 47 is pushed to The movable block 46 is engaged with the support plate 47 and the support plate 47 is engaged with the support plate 47.

The reset plate 49 and the lifting column 48 are squeezed by the pressure on the pressing shell 45 on the fixing seat 41, so that the reset plate 49 contracts to adjust the activity space inside the pressing shell 45, so that the pressing shell 45 contracts and pushes the lifting column 48 down, so that the contraction of the pressing shell 45 is used to apply pressure, and the reset plate 49 and the pressing shell 45 are in contact to play a supporting role, so as to increase the bearing force of the pressing shell 45. When the pressing shell 45 loses pressure, the reset plate 49 resets and pushes the pressing shell 45 back to the initial position, so that the pressing shell 45 resets and drives the lifting column 48 up The reinforcing plate 47 is lifted and stopped from being squeezed. A limiting frame 410 is fixedly connected to the bottom of the inner cavity of the reset plate 49. The limiting frame 410 is inside the reset plate 49 so that the limiting frame 410 can limit the contraction range of the reset plate 49. When the top of the limiting frame 410 contacts the reset plate 49, the limiting frame 410 presses the pressing shell 45 through the reset plate 49, thereby increasing the bearing capacity of the pressing shell 45 itself, and can limit the contraction range of the pressing shell 45, so that the pressing shell 45 has a movable space inside when being pressed, which is convenient for the limiting frame 410 to protect the reset plate 49. The outer surface of the limiting frame 410 extends to the outside of the reset plate 49.

[0058] The lifting column 48 is fixedly connected to the top of the inner cavity of the pressing shell 45. The lifting column 48 drives the fixed column 411 to move through the lifting and lowering of the lifting column 48, so that the fixed column 411 and the lifting column 48 can cooperate to extend the contact range. The lifting column 48 penetrates the pressing shell 45 and the fixed seat 41, so that the lifting column 48 can locate the installation position of the pressing shell 45 to prevent the displacement of the pressing shell 45 from affecting the movement of the lifting column 48, so that the lifting and lowering of the lifting column 48 is restricted by the pressing shell 45 and the fixed seat 41, thereby ensuring the lifting and lowering movement of the lifting column 48 and the fixed column 411 in the vertical direction. The outer surface of the lifting column 48 is slidably connected to the fixed seat 41, and the bottom end of the lifting column 48 is fixedly connected with the fixed column 411, the outer surface of the fixed column 411 is fixedly connected with an external plate 412, and the external plate 412 is distributed in a circular shape on the fixed column 411, so that the external plate 412 can be raised and lowered along with the fixed column 411, so that when the external plate 412 descends to contact the reinforcing plate 47, the external plate 412 applies pressure to the reinforcing plate 47 to push the reinforcing plate 47 to move, so that the pressure of the external plate 412 and the reinforcing plate 47 is adjusted to prevent the movement of the reinforcing plate 47 inside the pressing shell 45 from being affected, and when the external plate 412 contacts the reinforcing plate 47 and is not released, the reinforcing plate 47 can be pressed to prevent the reinforcing plate 47 from sliding, thereby ensuring the stability of the reinforcing plate 47 when pushing the extrusion frame 43 to move.

[0059] The bottom end of the lifting column 48 passes through the pressing shell 45 , and the bottom of the external plate 412 is slidably connected to the reinforcing plate 47 .

[0060] Among them, the protection component 5 includes a placement seat 51, which is fixedly connected to the top of the base 1. The placement seat 51 is used to place steel bars. The steel bars are placed on the base 1 through the placement seat 51, so that the placement seat 51 guides the steel bars to enter the guide seat 57, which is convenient for the steel bars to be loaded along the placement seat 51, so that the steel bars are not easy to contact the base 1 during loading, so that the placement seat 51 is used to protect the steel bars, thereby improving the firmness of the placement of the steel bars, and the placement seat 51 corresponds to the guide seat 57, so that the steel bars on the placement seat 51 are not easy to deviate when entering the guide seat 57, thereby ensuring the convenience of the steel bars moving inside the guide seat 57, so that the placement seat 51 and the guide seat 57 cooperate to protect the steel bars The outer surface of the placement seat 51 is slidably connected with an adjusting rod 56, and the adjusting rod 56 is moved on the placement seat 51 by the thrust, so that the adjusting rod 56 pushes the limiting plate 52 to contact the steel bar, so that the limiting plate 52 can limit the position of the steel bar and avoid the movement of the steel bar during transportation. The adjusting rod 56 cooperates with the limiting plate 52 to pre-clamp the steel bar. The adjusting rod 56 is pulled to drive the limiting plate 52 away from the steel bar, so that the movement of the adjusting rod 56 on the placement seat 51 adjusts the restricted space of the steel bar, which is convenient for adjusting the position of the limiting plate 52 according to the volume of the steel bar, so as to avoid the limiting plate 52 affecting the movement of the steel bar. The limiting plate 52 is fixedly connected to one end of the adjusting rod 56 close to the placement seat 51;

[0061] The guide seat 57 is fixedly connected to the top of the base 1. The guide seat 57 is used to guide the movement of the steel bar. The top of the guide seat 57 is fixedly connected with a support plate 55. The lifting cylinder 54 is fixed on the guide seat 57 through the support plate 55, so that the lifting cylinder 54 can be extended and retracted on the support plate 55 to approach the steel bar, so that the support plate 55 can protect the lifting cylinder 54 and prevent the lifting cylinder 54 from loosening or falling off on the support plate 55. The installation position of the support plate 55 and the support plate 55 is not easy to affect the movement of the steel bar, ensuring that the lifting cylinder 54 can perform vertical lifting movement, and the support plate 55 can play a reinforcing role on the guide seat 57. In order to avoid bending of the guide seat 57 when it enters the position of the steel bar, a lifting cylinder 54 is fixedly connected to the top of the support plate 55, and a knocking block 53 is fixedly connected to the bottom of the lifting cylinder 54. The knocking block 53 is lifted and lowered by the lifting cylinder 54, so that the knocking block 53 repeatedly knocks on the steel bar, which is convenient for the knocking block 53 to correct the bending position of the steel bar, avoiding the situation where the steel bar is bent and caused to get stuck during transportation, and the movement of the knocking block 53 is controlled by the lifting cylinder 54, which is convenient for the lifting cylinder 54 to move the knocking block 53 according to the degree of bending of the steel bar, preventing the knocking block 53 from bending the steel bar when knocking it, thereby affecting the subsequent processing of the steel bar.

[0062] Among them, the side of the guide seat 57 close to the limiting plate 52 is fixedly connected to the placement seat 51, and the point of the lifting cylinder 54 passes through the support plate 55.

[0063] The inner surface of the guide seat 57 is fixedly connected with a protective ring 58, and the guide seat 57 is used to guide the steel bar after being knocked, so that the steel bar passes through the protective ring 58 inside the guide seat 57, so that the guide seat 57 and the protective ring 58 cooperate to protect the transportation, and avoid the situation that the steel bar moves around and causes bending during transportation. The guide seat 57 is close to the feeding assembly 6, so that the steel bar leaves the guide seat 57 and enters the feeding assembly 6 for transportation, which is convenient for the steel bar to be positioned inside the guide seat 57, thereby improving the accuracy of steel bar transportation, so that the guide seat 57 plays a role in positioning while guiding the steel bar. The outer surface of the protective ring 58 is fixedly connected with an inner support plate 59, through which the steel bar is fixedly supported. The inner support plate 59 is distributed in a circle on the protective ring 58, so that the inner support plate 59 is connected to the guide seat 57 to fix the protective ring 58, thereby reinforcing the installation position of the protective ring 58, avoiding the protective ring 58 from loosening inside the guide seat 57 and affecting the movement of the steel bar, so that the inner support plate 59 and the protective ring 58 cooperate with each other to contact different positions of the guide seat 57, which is convenient for sharing the pressure when it is subjected to pressure, and the position of the protective ring 58 away from the inner support plate 59 is fixedly connected with a buffer frame 510, and the buffer frame 510 contacts the guide seat 57 on the protective ring 58, so that the buffer frame 510 is subjected to the pressure of the steel bar and shrinks, so that the buffer frame 510 protects the protective ring 58 while guiding The placement of the steel bars avoids excessive wear and tear that affects the use of the steel bars when they move inside the guide seat 57. The installation positions of the buffer frame 510 and the inner support plate 59 cooperate with each other, so that the buffer frame 510 presses the inner support plate 59 tightly to ensure the stability of the connection position of the buffer frame 510. The inner surface of the protective ring 58 is rotatably connected with an active ball 511. The active ball 511 is driven by the steel bars to roll, so that the active ball 511 moves on the protective ring 58, which can reduce the friction when the steel bars move, and facilitate the movement of the steel bars. The active ball 511 and the buffer frame 510 cooperate with each other to guide the placement of the steel bars, avoiding the steel bars from moving around inside the guide seat 57 and colliding. The shaking of the movable ball 511 is restricted by the protective ring 58, so that the movable ball 511 is not easy to separate from the protective ring 58 when moving, thereby ensuring the convenience of the movable ball 511 movement. The protective ring 58 is fixedly connected with an inner plate 512 at a position away from the movable ball 511. The inner plate 512 can protect the position away from the movable ball 511 on the protective ring 58, so that the inner plate 512 can guide the movement of the steel bar when it contacts the steel bar, thereby reducing the contact between the steel bar and the protective ring 58, and the inner plate 512 can be reinforced on the protective ring 58, so that the inner plate 512 can play a buffering effect on the protective ring 58, thereby ensuring the movable space of the steel bar inside the protective ring 58.

[0064] The inner support plate 59 is fixedly connected to the guide seat 57 at one side away from the protective ring 58 , and the buffer frame 510 is fixedly connected to the guide seat 57 at one side away from the protective ring 58 .

[0065] The feeding assembly 6 includes an assembly plate 61, which is fixedly connected to the top of the base 1. The assembly plate 61 corresponds to the guide seat 57 through the assembly plate 61, so that the steel bar passes through the assembly plate 61 and moves, so that the assembly plate 61 can limit the movement of the steel bar. At the same time, the assembly plate 61 is located between the guide seat 57 and the fixed seat 41, so that the assembly plate 61 can play a role of separation, so as to limit the position of the steel bar leaving the guide seat 57 by utilizing the installation position of the assembly plate 61. The inner surface of the assembly plate 61 is rotatably connected with a screw rod 62, and the screw rod 62 is driven by the motor to rotate clockwise, so that the screw rod 62 drives the two displacement blocks 63 to approach each other, and the screw rod 62 rotates counterclockwise to drive the displacement blocks 63 away from each other, so that the rotation of the screw rod 62 adjusts the position of the displacement block 63. When the screw 62 drives the displacement block 63 to move, it is restricted by the assembly plate 61, so that the assembly plate 61 and the screw 62 cooperate to guide the movement of the displacement block 63 to prevent the displacement block 63 from jamming when moving. The outer surface of the screw 62 is rotatably connected with the displacement block 63;

[0066] The connecting frame 65 is fixedly connected to the bottom of the displacement block 63. The connecting frame 65 is driven by the displacement block 63 to move, so that the connecting frame 65 drives the feeding roller frame 66 to contact the steel bar, which is convenient for the feeding roller frame 66 to limit the steel bar. As the feeding roller frame 66 rotates, the contacted pipe rack is transported, so that the rotation of the feeding roller frame 66 is used to achieve the effect of automatic feeding, and the movement of the connecting frame 65 can be adjusted according to the volume of the steel bar, so that the connecting frame 65 is not easily affected during the movement, ensuring that the feeding roller frame 66 fully contacts the steel bar for transportation. The top of the inner cavity of the connecting frame 65 is rotatably connected to The feeding roller frame 66 and the connecting frame 65 are fixedly connected with a telescopic rod 64 on one side close to the assembly plate 61. The telescopic rod 64 is contracted by the movement of the connecting frame 65, so that the telescopic rod 64 can support the connecting frame 65 on the assembly plate 61, which is convenient for the telescopic rod 64 to vibrate the connecting frame 65 itself to ensure its stability and prevent the connecting frame 65 from tilting when moving and affecting the transportation of steel bars. The telescopic rod 64 and the displacement block 63 can be used to fix the connecting frame 65 from different positions, thereby improving the stability of the connecting frame 65 when moving. The outer surface of the telescopic rod 64 is fixedly connected to the assembly plate 61.

[0067] Example 2, please refer to Figure 1-Figure 12, on the basis of Example 1, the present invention provides a technical solution: a method for using a steel bar bending device for construction engineering, step 1: placing the steel bar to be bent on the placement seat 51, the adjusting rod 56 applies thrust to push the limiting plate 52 to stop when it contacts the bar, and the steel bar continues to move through the guide seat 57 and the assembly plate 61, and the motor drives the screw rod 62 on the assembly plate 61 to rotate clockwise, so that the screw rod 62 drives the two displacement blocks 63 to approach each other, and the displacement block 63 drives the connecting frame 65 to move, and as the feeding roller frame 66 on the connecting frame 65 contacts the steel bar, it stops, so that the feeding roller frame 66 moves to transport the steel bar, and when the connecting frame 65 moves, the telescopic rod 64 is pulled to extend, and the screw 62 rotates counterclockwise to drive the two displacement blocks 63 away from each other, so that the connecting frame 65 drives the feeding roller frame 66 away from the steel bar, and at the same time, the connecting frame 65 pushes the telescopic rod 64 to shrink;

[0068] Step 2: When the steel bar bends before entering the guide seat 57, the lifting cylinder 54 extends and retracts on the support plate 55 to push the knocking block 53 up and down, so that the knocking block 53 knocks on the bending position of the steel bar. With the multiple extension and retraction movements of the lifting cylinder 54, the steel bar is knocked multiple times, so that the steel bar continues to enter the guide seat 57 after the knocking is completed. When the steel bar is knocked, the limiting plate 52 limits the position of the steel bar, and the adjusting rod 56 is pulled on the placement seat 51 to drive the limiting plate 52 away from the steel bar;

[0069] Step 3: Use the inner support plate 59 to form a protective ring 58 inside the guide seat 57, so that the steel bar passes through the protective ring 58. When the steel bar passes through the protective ring 58 and contacts the buffer frame 510, the steel bar presses the buffer frame 510 to shrink. When the steel bar contacts the movable ball 511 and moves inside the protective ring 58, the movable ball 511 rolls under the drive of the steel bar. When the inner plate 512 contacts the steel bar inside the protective ring 58, it shrinks under the pressure of the steel bar, so that the inner plate 512 protects the protective ring 58, so that the protective ring 58 and the inner plate 512 guide the movement of the steel bar. The inner plate 512 loses the pressure of the steel bar and is reset on the protective ring 58;

[0070] Step 4: When the steel bars are transported to the extrusion frame 43 by the feeding roller frame 66, the fixed seat 41 fixes the rotating column 42 and the movable block 46. As the pressing shell 45 contracts under pressure, the lifting column 48 is pushed down, and the reset plate 49 contracts under the pressure of the pressing shell 45. The reset plate 49 stops moving when it contracts to the contact limit frame 410. The lifting column 48 moves down and drives the fixed column 411 to move, so that the fixed column 411 drives the external plate 412 to squeeze the reinforcement plate 47. The reinforcement plate 47 is pressed and drives the movable block 46 to rotate inside the fixed seat 41.

[0071] Step 5: Use the reinforcement plate 47 to apply thrust to the extrusion frame 43 as the movable block 46 rotates, so that the extrusion frame 43 drives the rotating column 42 to rotate with the booster plate 44. The booster plate 44 cooperates with the reinforcement plate 47 on the fixed seat 41 to press the extrusion frame 43 to bend and clamp the steel bar. Then the bending cylinder 9 contracts and drives the connecting plate 8 to move on the base 1 in the direction close to the steel bar. When the connecting plate 8 moves, it drives the installation frame 3 to move through the moving block 2, so that the bending block 7 inside the installation frame 3 moves to contact the steel bar for bending. After the steel bar is bent, the bending cylinder 9 extends, so that the bending cylinder 9 drives the moving block 2 away from the steel bar through the connecting plate 8, and the installation frame 3 drives the bending block 7 to move with the moving block 2;

[0072] Step six: After the steel bar is bent, release the pressing shell 45, so that the reset plate 49 is reset and pushes the pressing shell 45 to rise. The pressing shell 45 rises and drives the fixed column 411 to move through the lifting column 48, so that the external plate 412 moves with the fixed column 411 and separates from the reinforcing plate 47. When the reinforcing plate 47 loses the pressure of the external plate 412, the movable block 46 rotates and resets to stretch the reinforcing plate 47, so that the extrusion frame 43 loses the thrust of the reinforcing plate 47 and releases the steel bar, thereby taking out the bent steel bar.
