[0056] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0057] like Figures 1-4 As shown, the present invention provides a steel bar bending processing equipment, including a bending device 1 and a limiting device 2. The bending device 1 includes a bending mechanism 11 and two bending mechanisms 12. In the first direction, the bending mechanism 11 is located between the two bending mechanisms 12. When the bending mechanism 11 clamps and bends multiple steel bars 100 in the second direction, the multiple steel bars 100 are arranged side by side along the third direction. The first direction, the second direction and the third direction are perpendicular to each other. One bending mechanism 12 can synchronously bend the first end of the multiple steel bars 100 to form a first hook structure, and the other bending mechanism 12 can synchronously bend the second end of the multiple steel bars 100 to form a second hook structure. The limiting device 2 includes a limiting platform 21, a limiting drive module 22 and two limiting blocks 23. The limit platform 21 is located on the side of a bending mechanism 12 away from the bending mechanism 11, the limit drive module 22 is arranged on the limit platform 21, and two limit blocks 23 are arranged at the output end of the limit drive module 22. A hook head 24 is provided on the limit block 23. When the bending mechanism 12 synchronously bends the second ends of multiple steel bars 100, the limit drive module 22 can drive the two limit blocks 23 to limit multiple first hook structures along the clamping direction. When the two limit blocks 23 limit multiple first hook structures along the clamping direction, the multiple first hook structures are arranged side by side along the third direction and are limited between the limit platform 21 and the hook head 24, and the clamping direction is perpendicular to the third direction.

[0058] In the present invention, when the bending mechanism 11 clamps and bends multiple steel bars 100 along the second direction, the multiple steel bars 100 are arranged side by side along the third direction, thereby realizing the synchronous bending processing of the multiple steel bars 100 and improving the processing efficiency. On this basis, by setting the limiting device 2, when the bending mechanism 12 synchronously bends the second ends of the multiple steel bars 100, the limiting driving module 22 can drive the two limiting blocks 23 to limit the multiple first hook structures along the clamping direction, so that the multiple first hook structures are arranged side by side along the third direction and limited between the limiting platform 21 and the hook head 24, which can ensure that the hook structures at both ends of the multiple steel bars 100 processed synchronously are on the same plane, and the two limiting blocks 23 can cooperate to limit and clamp steel bars 100 of various sizes. The bending device 1 and the limiting device 2 cooperate to avoid twisting of the two ends of the steel bars 100 on the basis of improving the processing efficiency, thereby ensuring the processing quality.

[0059] Specifically, the bending mechanism 11 includes a bending frame 111, a traction wheel 112, a traction drive, a bending drive 113, a movable support 114, and a bending pressure wheel 115. Two traction wheels 112 are provided, and the two traction wheels 112 are spaced apart along a first direction on the bending frame 111. The traction drive is provided on the bending frame 111 and can drive at least one traction wheel 112 to rotate about its own axis. The bending drive 113 is installed on the bending frame 111, and the movable support 114 is installed at the output end of the bending drive 113. The bending pressure wheel 115 is rotatably installed on the movable support 114. The bending drive 113 can drive the bending pressure wheel 115 to move along a second direction on a symmetrical plane of the two traction wheels 112 through the movable support 114. The rotation axes of the traction wheels 112 and the bending pressure wheel 115 are parallel to the third direction. When multiple steel bars 100 are sandwiched between the traction wheels 112 and the bending pressure wheel 115, they are arranged side by side along the third direction.

[0060] In this embodiment, the traction drive includes a motor, and the output end of the motor can be directly connected to the traction wheel 112, or the motor can drive one traction wheel 112 or two traction wheels 112 to rotate around their own axes through a conventional gear transmission mechanism or a belt transmission mechanism. The arc driver 113 is a driving mechanism such as a hydraulic cylinder or an electric cylinder.

[0061] Specifically, the bending mechanism 12 includes a shift driver 121 and a bending main unit 122. The bending main unit 122 is mounted on the conveying end of the shift driver 121. The shift driver 121 can drive the bending main unit 122 to move between a working position and a non-working position. When in the working position, the bending main unit 122 can synchronously bend the multiple steel bars 100 conveyed by the bending mechanism 11. When in the non-working position, the bending main unit 122 can avoid the multiple steel bars 100 conveyed by the bending mechanism 11. The bending mechanism 11 and the bending main unit 122 cooperate to bend the steel bars 100 based on the arc. The shift driver 121 drives the bending main unit 122 to bend the steel bars 100 in the working position and can also drive the bending main unit 122 to avoid the conveyed steel bars 100 in the non-working position. This adapts to the processing flow of the steel bars 100 and ensures smooth bending and curving of the steel bars 100.

[0062] More specifically, the bending mechanism 12 further includes a positioning mechanism 123. When the steel bar 100 conveyed by the bending mechanism 11 abuts against the positioning mechanism 123, the steel bar 100 is conveyed to the bending position, and the bending mechanism 12 is configured to bend the steel bar 100 at the bending position. The positioning mechanism 123 enables the bending mechanism 12 to accurately bend the steel bar 100 of a set length.

[0063] Specifically, the positioning mechanism 123 includes a positioning support, a movable platform and a pressure sensor. The positioning support is installed on the bending main unit 122. The movable platform is movably connected to the positioning support along a first direction. The pressure sensor is clamped between the positioning support and the movable platform. When the steel bar 100 abuts against the movable platform, it can trigger the pressure sensor. When the pressure sensor is triggered, it sends a signal to the controller. After receiving the signal, the controller controls the traction drive to stop moving.

[0064] More specifically, the positioning mechanism 123 also includes a driver, which can be a driving component such as a cylinder, installed on the bending main unit 122 or independently set relative to the bending main unit 122, and can drive the positioning support to move between the positioning position and the avoidance position. At the positioning position, the positioning mechanism 123 can position the delivered steel bar 100 at the bending position. At the avoidance position, it does not affect the delivery of the steel bar 100.

[0065] In this embodiment, the shift driver 121 is a conventional linear drive mechanism such as a hydraulic cylinder, electric cylinder, etc. in this field, and the bending main unit 122 is a conventional bending main unit in this field, which is provided with a positioning part and a rotating part. When in the working position, the steel bar 100 can be transported between the positioning part and the rotating part, and then the rotating part is driven by a driver such as a motor to rotate with the positioning part as the axis, thereby finally realizing the bending of the steel bar 100.

[0066] Specifically, the two opposite sides of the bending mechanism 11 are the first side and the second side, respectively. One bending mechanism 12 is located on the first side of the bending mechanism 11, and the other bending mechanism 12 is located on the second side of the bending mechanism 11. The two bending mechanisms 12 on both sides of the bending mechanism 11 have the same structure and are symmetrically arranged. Therefore, in the two bending mechanisms 12, the working position and non-working position of the two bending main machines 122 are symmetrically arranged relative to the bending mechanism 11. In the two bending mechanisms 12, the bending positions of the two positioning mechanisms 123 that limit the steel bars 100 are symmetrically arranged relative to the bending mechanism 11.

[0067] More specifically, the steel bar bending processing equipment further includes a base frame 13 , on which the bending mechanism 11 and the two bending mechanisms 12 are mounted, and the bending mechanism 11 and the two bending mechanisms 12 are located on the same side of the base frame 13 .

[0068] In this embodiment, the bending main unit 122 is connected to the base frame 13 in a sliding manner along the second direction, and the shift driver 121 is installed on the base frame 13 to drive the bending main unit 122 .

[0069] In other embodiments, the bending main unit 122 may be slidably connected to the base frame 13 along the third direction, and the shift driver 121 drives the bending main unit 122 to move in the third direction.

[0070] In the steel bar bending processing equipment of this embodiment, the controller can coordinately control the bending mechanism 11 and the two bending mechanisms 12. The specific circuit connection relationship and control principle are existing technologies and will not be repeated here.

[0071] Specifically, the limiting platform 21 is provided with a limiting platform 211. When the bending mechanism 12 simultaneously bends the second ends of the plurality of steel bars 100, the plurality of first hook structures are supported by the limiting platform 211 and are limited in the third direction between the limiting platform 211 and the hook head 24. The limiting platform 211 can stably support the plurality of first hook structures.

[0072] More specifically, the limiting table 211 is provided with a protruding hole 212, and the limiting driving module 22 is capable of driving the two limiting blocks 23 to move between an extended position and a retracted position. In the extended position, the two limiting blocks 23 extend out of the limiting table 211 through the protruding hole 212, and in the retracted position, the two limiting blocks 23 are retracted from the outside of the limiting table 211. By providing the protruding hole 212, the two limiting blocks 23 are retracted from the outside of the limiting table 211, thereby avoiding interference with the conveying process of the steel bars 100.

[0073] In this embodiment, the first direction and the second direction both extend in the horizontal direction, and the third direction extends in the vertical direction. The limiting table 211 is a horizontal plane, and a guide surface 213 is provided on one side of the limiting table 211. The guide surface 213 gradually extends downward in the direction approaching the arc bending device 1, thereby being able to smoothly guide the arc bending mechanism 11 to the limiting table 211.

[0074] Specifically, the limit drive module 22 includes a first limit drive 221 and a second limit drive 222. The first limit drive 221 is mounted on the limit platform 21, and the second limit drive 222 is mounted at the output end of the first limit drive 221. The first limit drive 221 is capable of driving the second limit drive 222 to move in the third direction. Two limit blocks 23 are disposed at the output end of the second limit drive 222, and the second limit drive 222 is capable of driving the two limit blocks 23 to move toward or away from each other along the clamping direction. This arrangement enables the limit drive module 22 to flexibly drive the two limit blocks 23 to move upward, downward, and in a clamping manner.

[0075] More specifically, the limit drive module 22 includes a first bearing block 223 and a second bearing block 224. The first limit drive 221 is connected to the limit platform 21 via the first bearing block 223, and the second limit drive 222 is connected to the first limit drive 221 via the second bearing block 224. This arrangement makes the assembly of the first limit drive 221 and the second limit drive 222 more stable and reliable.

[0076] In this embodiment, the first limit actuator 221 is a driving mechanism such as a hydraulic cylinder or an electric cylinder, and the second limit actuator 222 is a pneumatic finger or a structure in which two cylinders cooperate.

[0077] Specifically, when the two limit blocks 23 limit the plurality of first hook structures along the clamping direction, the hook heads 24 on the two limit blocks 23 are arranged side by side in the third direction. The above arrangement allows the two hook heads 24 to successively limit the openings of the two limit blocks 23, which is safer and more reliable.

[0078] More specifically, the two limiting blocks 23 are each provided with a first limiting surface 231 on one side thereof facing each other. The two first limiting surfaces 231 are parallel to each other and spaced apart. The multiple first hook structures can be limited in the clamping direction between the two first limiting surfaces 231. The multiple first hook structures are clamped by the two first limiting surfaces 231, which is safer and more reliable.

[0079] More specifically, the hook head 24 is provided with a second limiting surface 241. When the plurality of first curved hook structures are limited between the limiting platform 21 and the second limiting surface 241 along the third direction, the second limiting surface 241 of the hook head 24 gradually moves away from the limiting platform 21 in a direction away from the connected limiting block 23. This arrangement enables the second limiting surface 241 to gradually press down the first curved hook structure between the two first limiting surfaces 231 when the two first limiting surfaces 231 approach each other, thereby enhancing safety and reliability and achieving a better limiting effect.

[0080] In this embodiment, the limiting block 23 and the hook head 24 are integrally formed, the first limiting surface 231 and the second limiting surface 241 are smoothly transitioned, and the hook head 24 on one limiting block 23 is higher than the hook head 24 on the other limiting block 23 .

[0081] The present invention also provides a steel bar processing method, which uses the above-mentioned steel bar bending processing equipment, including the following steps:

[0082] Step 1: The bending mechanism 11 clamps a plurality of steel bars 100 and conveys a first set length to a first side.

[0083] Step 2: The bending mechanism 12 on the first side bends the first ends of the plurality of steel bars 100 to form a first hook structure.

[0084] Step 3: The bending mechanism 11 clamps the plurality of steel bars 100 and continues to convey the steel bars 100 to the first side by a second set length.

[0085] Step 4: The bending mechanism 11 clamps the plurality of steel bars 100 and conveys the steel bars 100 to the second side by a third set length.

[0086] Step 5: The limiting drive module 22 drives the two limiting blocks 23 to limit the multiple first hook structures along the clamping direction, so that the multiple first hook structures are arranged side by side along the third direction and limited between the limiting platform 21 and the hook head 24.

[0087] Step 6: The bending mechanism 12 on the second side bends the second ends of the plurality of steel bars 100 to form a second hook structure.

[0088] In the present invention, when the bending mechanism 11 clamps and bends multiple steel bars 100 along the second direction, the multiple steel bars 100 are arranged side by side along the third direction, thereby realizing the synchronous bending processing of the multiple steel bars 100 and improving the processing efficiency. On this basis, by setting the limiting device 2, when the bending mechanism 12 synchronously bends the second ends of the multiple steel bars 100, the limiting driving module 22 can drive the two limiting blocks 23 to limit the multiple first hook structures along the clamping direction, so that the multiple first hook structures are arranged side by side along the third direction and limited between the limiting platform 21 and the hook head 24, which can ensure that the hook structures at both ends of the multiple steel bars 100 processed synchronously are on the same plane, and the two limiting blocks 23 can cooperate to limit and clamp steel bars 100 of various sizes. The bending device 1 and the limiting device 2 cooperate to avoid twisting of the two ends of the steel bars 100 on the basis of improving the processing efficiency, thereby ensuring the processing quality.

[0089] Based on the specific structure of the above-mentioned steel bar bending processing equipment, the specific steps of the steel bar processing method are described below:

[0090] S1. The shift driver 121 of the bending mechanism 12 on the first side drives the bending main unit 122 to the working position, and the shift driver 121 of the bending mechanism 12 on the second side drives the bending main unit 122 to the non-working position.

[0091] In this step, by adjusting the positions of the two bending main machines 122, the bending main machine 122 on the first side can receive the steel bars 100 delivered by the bending mechanism 11, and the bending main machine 122 on the second side avoids the delivery path of the steel bars 100. In addition, the driver of the positioning mechanism 123 on the first side drives the positioning support to move to the positioning position, and the driver of the positioning mechanism 123 on the second side drives the positioning support to move to the avoidance position, preparing for the bending operation of the bending main machine 122 on the first side.

[0092] S2. Transport a set number of steel bars 100 from the feed side to one side of the two traction wheels 112 facing the bending and pressing wheels 115.

[0093] The first side of the bending mechanism 11 is the discharging side, and the second side is the feeding side. In this step, a set number of steel bars 100 are passed from the feeding side over the bending mechanism 12 and gradually extended between the traction wheel 112 and the bending pressure wheel 115. Then the traction drive can drive the traction wheel 112 to rotate, so that the steel bars 100 can be input more efficiently.

[0094] S3. The bending driver 113 drives the bending pressure wheel 115 to approach the traction wheel 112 through the mobile support 114, so that a set number of steel bars 100 are sandwiched between the traction wheel 112 and the bending pressure wheel 115.

[0095] In this step, the arc bending pressure wheel 115 is close to the traction wheel 112 and clamps a set number of steel bars 100, so that the multiple steel bars 100 are arranged side by side along the third direction.

[0096] S4. The arc bending driver 113 drives the arc bending pressure wheel 115 to continue to approach the traction wheel 112 through the mobile support 114 until the arc bending pressure wheel 115 and the two traction wheels 112 cooperate to synchronously bend a set number of steel bars 100 to a set arc.

[0097] In this step, the bending driver 113 drives the bending pressure wheel 115 to move through the mobile support 114, and simultaneously performs bending operations on multiple steel bars 100.

[0098] S5. The traction driver drives the traction wheel 112 to rotate, and transports the steel bar 100 while bending the steel bar 100.

[0099] In this step, the traction wheel 112 rotates in one direction to bend a set number of steel bars 100 while conveying them toward the bending main machine 122 on the first side.

[0100] S6. The bending mechanism 11 clamps the plurality of steel bars 100 and conveys the steel bars 100 to the first side by a first set length.

[0101] The steel bar 100 passes between the positioning part and the rotating part of the bending main unit 122 until it abuts against the positioning mechanism 123 on the first side. At this time, the steel bar 100 is transported to the first side to a first set length and moves to the bending position. The traction wheel 112 stops rotating, and the length of the steel bar 100 passing through the bending main unit 122 reaches the preset length.

[0102] S7. The bending mechanism 12 on the first side bends the first ends of the plurality of steel bars 100 to form a first hook structure.

[0103] In this step, the bending main unit 122 on the first side simultaneously bends a set number of steel bars 100, and the rotating part of the bending main unit 122 rotates around the positioning part as the axis, and finally the steel bars 100 of the preset length are bent. During the bending operation, the bending main unit 122 bends multiple steel bars 100 synchronously, which is time-saving, efficient and consistent.

[0104] S8. The shift driver 121 on the first side drives the bending main unit 122 to the non-working position.

[0105] In this step, the bending main unit 122 on the first side is driven by the shift driver 121 to move along the extension direction of the first hook structure of the steel bar 100, so that the first hook structure is disengaged from the bending main unit 122, and the driver of the positioning mechanism 123 on the first side drives the positioning support to move to the avoidance position.

[0106] S9, the bending mechanism 11 clamps the plurality of steel bars 100 and continues to convey the steel bars 100 to the first side to a second set length.

[0107] In this step, the traction drive drives the traction wheel 112 to continue rotating until the bending mechanism 11 completes the bending of a set number of steel bars 100. During this process, since the bending main unit 122 is in the non-working position, the steel bars 100 can be smoothly bent by the bending mechanism 11 until they are bent to the specified position.

[0108] S10 , the shift driver 121 on the second side drives the bending main unit 122 to the working position.

[0109] In this step, by adjusting the position of the bending main machine 122 on the second side, the bending main machine 122 on the second side can receive the steel bars 100 transported in reverse by the bending mechanism 11, and the driver of the positioning mechanism 123 on the second side drives the positioning support to move to the positioning position, preparing for the bending operation of the bending main machine 122 on the second side.

[0110] S11 , the bending mechanism 11 clamps the plurality of steel bars 100 and conveys the steel bars 100 to the second side by a third set length.

[0111] In this step, the traction drive drives the traction wheel 112 to rotate in the opposite direction to transport the steel bars 100 in the opposite direction. Corresponding to S5, the traction wheel 112 rotates in the other direction to transport a set number of steel bars 100 toward the bending main unit 122 on the second side. At this time, the bending main unit 122 on the first side is in a non-working position and does not interfere with the transportation of the steel bars 100.

[0112] S12: When the steel bar 100 abuts against the positioning mechanism 123 on the second side, the traction wheel 112 stops rotating.

[0113] In this step, the steel bar 100 passes between the positioning portion and the rotating portion of the bending main unit 122 on the second side until it abuts against the positioning mechanism 123 on the second side. At this time, the steel bar 100 moves to the bending position, and the length of the steel bar 100 passing through the bending main unit 122 on the second side reaches the preset length. At this time, the first hook structure is located above the exploration hole 212.

[0114] S13 , the limiting drive module 22 drives the two limiting blocks 23 to limit the multiple first hook structures along the clamping direction, so that the multiple first hook structures are arranged side by side along the third direction and are limited between the limiting platform 21 and the hook head 24 .

[0115] In this step, the first limit driver 221 drives the two limit blocks 23 to extend from the probe hole 212 to the limit table 211 through the second limit driver 222, so that the first hook structure extends between the two limit blocks 23, and then the second limit driver 222 drives the two limit blocks 23 to move toward each other along the clamping direction, so that multiple first hook structures are arranged side by side along the third direction and limited between the limit platform 21 and the hook head 24. The limit drive module 22 limits the multiple first hook structures to prevent the first hook structure from twisting when the bending main unit 122 on the second side processes the steel bar 100.

[0116] S14. The bending mechanism 12 on the second side bends the second ends of the plurality of steel bars 100 to form a second hook structure.

[0117] In this step, the rotating part of the bending main unit 122 on the second side rotates with the positioning part as the axis, and finally realizes the bending of the preset length of the steel bar 100. During the bending operation, the bending main unit 122 on the second side bends multiple steel bars 100 synchronously to form a second hook structure, which is time-saving, efficient and consistent. At this point, after the steel bar 100 is bent, both ends are bent to obtain the bottom bar of the required structural size.

[0118] S15 , the shift driver 121 on the second side drives the bending main unit 122 to the non-working position.

[0119] In this step, the bending main unit 122 is driven by the shift driver 121 to move along the extending direction of the bent section of the steel bar 100 , so that the second hook structure of the bent steel bar 100 is disengaged from the bending main unit 122 on the second side.

[0120] S16 , the limiting driving module 22 drives the two limiting blocks 23 to release the multiple first hook structures.

[0121] In this step, the second limiting driver 222 drives the two limiting blocks 23 to move in opposite directions along the clamping direction, releasing the multiple first hook structures, and then the first limiting driver 221 drives the two limiting blocks 23 to retract from the outside of the limiting table 211 through the second limiting driver 222.

[0122] S17, removing the steel bar 100 from the bending mechanism 11.

[0123] In this step, the processed steel bars 100 are removed from the bending mechanism 11 manually or by a robot and placed in a storage area.

[0124] S18. Prepare the next batch of steel bars 100.

[0125] Thereafter, steps S1 to S17 are repeated to process the reinforcing bar 100 .
