[0055] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0056] As Figures 1-5 shown, the present utility model provides a steel bar processing device, which includes a steel bar bending arc device 1. The steel bar bending arc device 1 includes a bending arc frame 11, a traction wheel 12, a traction driver, a bending arc driver 13, a moving support 14, a bending arc pressing wheel 15, and a limiting mechanism 16. Among them, two traction wheels 12 are provided, and the two traction wheels 12 are arranged at intervals along the first direction on the bending arc frame 11. The traction driver is arranged on the bending arc frame 11 and can drive at least one traction wheel 12 to rotate around its own axis. The bending arc driver 13 is installed on the bending arc frame 11. The moving support 14 is installed at the output end of the bending arc driver 13. The bending arc pressing wheel 15 is rotatably installed on the moving support 14. The limiting mechanism 16 is installed on the moving support 14. The bending arc driver 13 can drive the bending arc pressing wheel 15 to move along the second direction on the symmetry plane of the two traction wheels 12 through the moving support 14. The rotation axes of the traction wheel 12 and the bending arc pressing wheel 15 are both parallel to the third direction. When a plurality of steel bars 100 are clamped between the traction wheel 12 and the bending arc pressing wheel 15, they are arranged side by side along the third direction and are located between the bending arc frame 11 and the limiting mechanism 16. The first direction, the second direction, and the third direction are perpendicular to each other in pairs.

[0057] In the present utility model, when a plurality of steel bars 100 are clamped between the traction wheel 12 and the bending arc pressing wheel 15, they are located between the bending arc frame 11 and the limiting mechanism 16. The limiting mechanism 16 blocks the steel bars 100 at the gap opening between the traction wheel 12 and the bending arc pressing wheel 15, avoiding the steel bars 100 from protruding and warping out of the traction wheel 12 and the bending arc pressing wheel 15, and ensuring that the arcs of multiple steel bars 100 processed synchronously are consistent.

[0058] In this embodiment, the traction driver includes a motor. The output end of the motor can be directly connected to the traction wheel 12, or the motor can drive one traction wheel 12 or two traction wheels 12 to rotate around their own axes through a conventional gear transmission mechanism or belt transmission mechanism. The bending arc driver 13 is a driving mechanism such as a hydraulic cylinder or an electric cylinder.

[0059] Specifically, the limiting mechanism 16 includes a limiting bracket 161 and a limiting pressure wheel 162. Among them, the limiting bracket 161 is arranged on the moving support 14, and the limiting pressure wheel 162 is rotatably arranged on the limiting bracket 161, and the rotation axis is parallel to the second direction. When a plurality of steel bars 100 are clamped between the traction wheel 12 and the arc-bending pressure wheel 15, they are located between the arc-bending frame 11 and the limiting pressure wheel 162. The above setting makes the friction between the steel bar 100 and the limiting pressure wheel 162 a rolling friction, which facilitates the more smooth conveying of the steel bar 100.

[0060] More specifically, the limiting bracket 161 is arranged on the moving support 14 with adjustable position along the third direction, so that the size specifications and quantities of the steel bars 100 clamped between the traction wheel 12 and the arc-bending pressure wheel 15 are more flexible and variable.

[0061] In this embodiment, the limiting mechanism 16 further includes a support screw 163 and two limiting nuts 164. Among them, the support screw 163 is fixed on the moving support 14, and the axis is parallel to the third direction. The two limiting nuts 164 are respectively screwed on the support screw 163, and the limiting bracket 161 is clamped between the two limiting nuts 164. The above setting makes the position adjustment of the limiting bracket 161 relative to the moving support 14 simpler and more accurate.

[0062] In other embodiments, the limiting mechanism 16 further includes a linear driving mechanism such as a hydraulic cylinder and an electric cylinder, and the linear driving mechanism directly drives the limiting bracket 161 to move along the third direction.

[0063] Specifically, two limiting pressure wheels 162 are provided, and the two limiting pressure wheels 162 are arranged on the limiting bracket 161 at intervals along the first direction. The two limiting pressure wheels 162 cooperate with each other to more reliably limit the steel bar 100.

[0064] More specifically, in the first direction, the axes of the two limiting pressure wheels 162 are located between the axes of the two traction wheels 12, further ensuring the reliability of the steel bar 100 limiting.

[0065] In this embodiment, when a plurality of steel bars 100 are clamped between the traction wheel 12 and the arc-bending pressure wheel 15, the limiting pressure wheel 162 is spaced from the outermost steel bar 100, ensuring that when the arc-bending driver 13 drives the arc-bending pressure wheel 15 to approach the traction wheel 12 through the moving support 14, the limiting pressure wheel 162 will not interfere with the steel bar 100.

[0066] Specifically, the steel bar processing equipment further includes a first steel bar bending device 2. The first steel bar bending device 2 and the steel bar arc bending device 1 are arranged side by side in the first direction. The steel bar arc bending device 1 can convey a plurality of steel bars 100 towards the first steel bar bending device 2, and the first steel bar bending device 2 can bend a plurality of steel bars 100 synchronously. The steel bar arc bending device 1 and the first steel bar bending device 2 cooperate to bend the steel bar 100 on the basis of arc bending.

[0067] More specifically, the first steel bar bending device 2 includes a first displacement driver 21 and a first bending main body 22. Among them, the first bending main body 22 is installed at the conveying end of the first displacement driver 21. The first displacement driver 21 can drive the first bending main body 22 to move between a first working position and a first avoidance position. When in the first working position, the first steel bar bending device 2 can bend the steel bar 100 conveyed by the steel bar arc bending device 1. When in the first avoidance position, the first steel bar bending device 2 can avoid the steel bar 100 conveyed by the steel bar arc bending device 1 to ensure the smooth arc bending of the steel bar 100.

[0068] More specifically, the first steel bar bending device 2 includes a first positioning mechanism 23. When the steel bar 100 conveyed by the steel bar arc bending device 1 abuts against the first positioning mechanism 23, the steel bar 100 is conveyed to the first bending position, and the first steel bar bending device 2 is configured to bend the steel bar 100 at the first bending position. By setting the first positioning mechanism 23, the first steel bar bending device 2 can accurately bend the steel bar 100 with a set length.

[0069] In this embodiment, the first displacement driver 21 is a conventional linear drive mechanism such as a hydraulic cylinder or an electric cylinder in the art, and the first bending main body 22 is a conventional bending main body in the art, which is provided with a positioning part and a rotating part. When in the first working position, the steel bar 100 can be conveyed between the positioning part and the rotating part, and then the rotating part is driven by a driver such as a motor to rotate around the positioning part as an axis, and finally the bending of the steel bar 100 is realized. The first positioning mechanism 23 includes a positioning support, a movable table and a pressure sensor. The positioning support is installed on the first bending main body 22, the movable table is movably connected to the positioning support in the first direction, the pressure sensor is clamped between the positioning support and the movable table, the steel bar 100 can trigger the pressure sensor when abutting against the movable table, and the pressure sensor sends a signal to the controller when triggered. After receiving the signal, the controller controls the traction driver to stop operating.

[0070] Specifically, the steel bar processing equipment further includes a second steel bar bending device 3, which is located on the side of the steel bar arc bending device 1 away from the first steel bar bending device 2. The steel bar arc bending device 1 can convey a plurality of steel bars 100 towards the second steel bar bending device 3, and the second steel bar bending device 3 can bend a plurality of steel bars 100 synchronously. Based on the steel bar arc bending device 1, the first steel bar bending device 2 and the second steel bar bending device 3 cooperate to bend the two ends of the steel bar 100 on the basis of arc bending.

[0071] More specifically, the second steel bar bending device 3 includes a second displacement driver 31 and a second bending main body 32. The second bending main body 32 is installed at the conveying end of the second displacement driver 31. The second displacement driver 31 can drive the second bending main body 32 to move between a second working position and a second avoidance position. When in the second working position, the second steel bar bending device 3 can bend the steel bar 100 conveyed by the steel bar arc bending device 1. When in the second avoidance position, the second steel bar bending device 3 can avoid the steel bar 100 conveyed by the steel bar arc bending device 1 to ensure the smooth arc bending of the steel bar 100.

[0072] More specifically, the second steel bar bending device 3 includes a second positioning mechanism 33. When the steel bar 100 conveyed by the steel bar arc bending device 1 abuts against the second positioning mechanism 33, the steel bar 100 is conveyed to the second bending position, and the second steel bar bending device 3 is configured to bend the steel bar 100 at the second bending position. By setting the second positioning mechanism 33, the second steel bar bending device 3 can accurately bend the steel bar 100 with a set length.

[0073] In this embodiment, the second displacement driver 31 is a conventional linear drive mechanism such as a hydraulic cylinder or an electric cylinder in the art, and the second bending main body 32 is a conventional bending main body in the art, which is provided with a positioning part and a rotating part. When in the second working position, the steel bar 100 can be conveyed between the positioning part and the rotating part, and then the rotating part is driven by a driver such as a motor to rotate around the positioning part as an axis, and finally the bending of the steel bar 100 is realized. The second positioning mechanism 33 includes a positioning support, a movable table and a pressure sensor. The positioning support is installed on the second bending main body 32, the movable table is movably connected to the positioning support along the second direction, and the pressure sensor is clamped between the positioning support and the movable table. When the steel bar 100 abuts against the movable table, the pressure sensor can be triggered, and when the pressure sensor is triggered, it sends a signal to the controller, and after receiving the signal, the controller controls the traction driver to stop acting.

[0074] Specifically, the steel bar processing equipment further includes a chassis 4. The steel bar bending arc device 1, the first steel bar bending device 2, and the second steel bar bending device 3 are all installed on the chassis 4. The steel bar bending arc device 1 is located between the first steel bar bending device 2 and the second steel bar bending device 3, and the first steel bar bending device 2 and the second steel bar bending device 3 are symmetrically arranged with respect to the steel bar bending arc device 1.

[0075] In this embodiment, the first bending main body 22 and the second bending main body 32 are respectively slidably connected to the chassis 4 along the second direction. The first displacement driver 21 and the second displacement driver 31 are both installed on the chassis 4 and drive the first bending main body 22 and the second bending main body 32 respectively.

[0076] In other embodiments, it may also be that the first bending main body 22 and the second bending main body 32 are respectively slidably connected to the chassis 4 along the third direction, and the first displacement driver 21 and the second displacement driver 31 respectively drive the first bending main body 22 and the second bending main body 32 to move along the third direction.

[0077] In the steel bar processing equipment of this embodiment, the controller can control the steel bar bending arc device 1, the first steel bar bending device 2, and the second steel bar bending device 3 cooperatively. The specific circuit connection relationship and control principle are prior art and will not be elaborated here. As Figure 4 shown, the steel bar bending arc device 1, the first steel bar bending device 2, and the second steel bar bending device 3 cooperate to be able to process the bottom bars in the shield segment steel bar cage.

[0078] For the top bars in the shield segment steel bar cage, in one embodiment, the steel bar bending arc device 1 works alone for processing; in another embodiment, the steel bar bending arc device 1 is the first steel bar bending arc device, and on the basis of the first steel bar bending arc device, a second steel bar bending arc device with the same structure as the first steel bar bending arc device is additionally provided. As Figure 5 shown, the second steel bar bending arc device processes the top bars.

[0079] The present utility model also provides a steel bar processing method, using the above-mentioned steel bar processing equipment, including the following steps:

[0080] Step 1: Convey a set number of steel bars 100 from the feeding side to one side of the two traction wheels 12 facing the bending arc pressing wheel 15.

[0081] Step 2: The bending arc driver 13 drives the bending arc pressing wheel 15 to approach the traction wheel 12 through the moving support 14, so that a set number of steel bars 100 are clamped between the traction wheel 12 and the bending arc pressing wheel 15 and are located between the bending arc frame 11 and the limiting mechanism 16.

[0082] Step 3: The arc bending driver 13 drives the arc bending pressure wheel 15 to continue to approach the traction wheel 12 through the mobile support 14, until the arc bending pressure wheel 15 and the two traction wheels 12 cooperate to synchronously bend a set number of steel bars 100 to a set arc.

[0083] Step 4: The traction driver drives the traction wheel 12 to rotate, and transports the steel bar 100 while bending the steel bar 100.

[0084] In the steel bar processing method of the utility model, when multiple steel bars 100 are clamped between the traction wheel 12 and the arc bending pressure wheel 15, they are located between the arc bending frame 11 and the limiting mechanism 16. The limiting mechanism 16 blocks the steel bars 100 at the gap opening between the traction wheel 12 and the arc bending pressure wheel 15, thereby preventing the steel bars 100 from bulging outward from the traction wheel 12 and the arc bending pressure wheel 15, and ensuring that the curvature of multiple steel bars 100 processed synchronously is consistent.

[0085] Based on the specific structure of the above-mentioned steel bar processing equipment, the specific steps of the steel bar processing method are described below:

[0086] S1. According to the diameter of the steel bar 100 and the number of steel bars to be processed at one time, the position of the limiting pressing wheel 162 in the third direction is adjusted.

[0087] In this step, by adjusting the positions of the two limit nuts 164 on the support screw 163, the position adjustment of the limit bracket 161 is achieved, and finally the position adjustment of the limit pressure wheel 162 is achieved, so that the limit pressure wheel 162 can limit the multiple steel bars 100 between the traction wheel 12 and the bending pressure wheel 15.

[0088] S2. The first shift driver 21 drives the first bending main machine 22 to the first working position, and the second shift driver 31 drives the second bending main machine 32 to the second avoidance position.

[0089] In this step, by adjusting the positions of the first bending main machine 22 and the second bending main machine 32, the first bending main machine 22 can receive the steel bars 100 delivered by the steel bar bending device 1, and the second bending main machine 32 avoids the delivery path of the steel bars 100, preparing for the bending operation of the first bending main machine 22.

[0090] S3, conveying a set number of steel bars 100 from the feed side to the side of the two traction wheels 12 facing the bending and pressing wheels 15.

[0091] In this step, the feeding side is the side of the second steel bar bending device 3 away from the steel bar bending device 1, that is, Figure 4 As a reference, the steel bar 100 is transported from right to left, gradually extending between the traction wheel 12 and the bending and pressing wheel 15, and then the traction drive can drive the traction wheel 12 to rotate, so that the steel bar 100 can be input more efficiently.

[0092] S4. The arc bending driver 13 drives the arc bending pressure wheel 15 to approach the traction wheel 12 through the moving support 14, so that a set number of steel bars 100 are clamped between the traction wheel 12 and the arc bending pressure wheel 15 and are located between the arc bending frame 11 and the limiting mechanism 16.

[0093] In this step, when the clamping is completed, a set number of steel bars 100 are arranged side by side in the third direction, and the limiting pressure wheel 162 on the limiting mechanism 16 is spaced from the outermost steel bar 100, ensuring that when the arc bending driver 13 drives the arc bending pressure wheel 15 to approach the traction wheel 12 through the moving support 14, the limiting pressure wheel 162 will not interfere with the steel bars 100.

[0094] S5. The arc bending driver 13 drives the arc bending pressure wheel 15 to continue approaching the traction wheel 12 through the moving support 14 until the arc bending pressure wheel 15 and the two traction wheels 12 cooperate to synchronously bend a set number of steel bars 100 to a set radian.

[0095] In this step, during arc bending, the limiting pressure wheel 162 limits the steel bars 100 throughout the process, preventing the steel bars 100 from protruding and warping outside between the arc bending pressure wheel 15 and the two traction wheels 12, and ensuring that the arc bending angles of multiple steel bars 100 are consistent.

[0096] S6. The traction driver drives the traction wheel 12 to rotate and convey the steel bars 100 while arc bending.

[0097] In this step, the traction wheel 12 rotates in one direction and conveys the steel bars 100 that are arc bent towards the first bending main machine 22.

[0098] S7. When the steel bars 100 abut against the first positioning mechanism 23, the traction wheel 12 stops rotating.

[0099] In this step, the steel bars 100 pass through between the positioning part and the rotating part of the first bending main machine 22 until they abut against the first positioning mechanism 23. At this time, the steel bars 100 move to the first bending position, and the length of the steel bars 100 passing through the first bending main machine 22 reaches the set length.

[0100] S8. The first bending main machine 22 synchronously bends a set number of steel bars 100.

[0101] In this step, the rotating part of the first bending main machine 22 rotates around the positioning part as the axis, and finally realizes the bending of the steel bars 100 with the set length. During the bending operation, the first bending main machine 22 bends multiple steel bars 100 synchronously, which is time-saving, efficient and has good consistency.

[0102] S9. The first displacement driver 21 drives the first bending main machine 22 to the first avoidance position.

[0103] In this step, the first bending main machine 22 is driven by the first displacement driver 21 to move along the extending direction of the bent section of the steel bar 100 , so that the bent portion of the steel bar 100 is released from the first bending main machine 22 .

[0104] S10, the traction driver drives the traction wheel 12 to continue rotating until the steel bar bending device 1 completes bending of a set number of steel bars 100.

[0105] In this step, since the first bending main unit 22 is located at the first avoidance position, the steel bar 100 can be smoothly bent by the steel bar bending device 1 until it is bent to a designated position, and the bending process is completed.

[0106] S11 , the second shift driver 31 drives the second bending main unit 32 to a second working position.

[0107] In this step, the position of the second bending main machine 32 is adjusted so that the second bending main machine 32 can receive the steel bars 100 reversely transported by the steel bar bending device 1 , thereby preparing for the second bending main machine 32 to perform a bending operation.

[0108] S12, the traction driver drives the traction wheel 12 to rotate in the reverse direction to transport the steel bars 100 in the reverse direction.

[0109] In this step, the traction wheel 12 rotates in another direction to convey a set number of steel bars 100 toward the second bending main machine 32 . At this time, the first bending main machine 22 is in the first avoidance position and does not interfere with the conveying of the steel bars 100 .

[0110] S13: When the steel bar 100 abuts against the second positioning mechanism 33, the traction wheel 12 stops rotating.

[0111] In this step, the steel bar 100 passes between the positioning portion and the rotating portion of the second bending main unit 32 until it abuts against the second positioning mechanism 33. At this time, the steel bar 100 moves to the second bending position, and the length of the steel bar 100 passing through the second bending main unit 32 reaches the set length.

[0112] S14, the second steel bar bending device 3 simultaneously bends a set number of steel bars 100.

[0113] In this step, if Figure 4 As shown, the rotating part of the second bending main machine 32 rotates with the positioning part as the axis, and finally realizes the bending of the steel bar 100 of a set length. During the bending operation, the second bending main machine 32 bends multiple steel bars 100 synchronously, 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 reinforcement of the required structural size.

[0114] S15. The second shift driver 31 drives the second bending main body 32 to the second avoidance position.

[0115] In this step, driven by the second shift driver 31, the second bending main body 32 moves along the extension direction of the bent section of the steel bar 100, so that the bent part of the steel bar 100 disengages from the second bending main body 32.

[0116] S16. The arc bending driver 13 drives the arc bending pressure wheel 15 away from the traction wheel 12 through the moving support 14.

[0117] In this step, driven by the moving support 14, the arc bending pressure wheel 15 and the limit pressure wheel 162 on the limit mechanism 16 move away from the processed steel bar 100, releasing the limit on the steel bar 100.

[0118] S17. Remove the steel bar 100 from the steel bar arc bending device 1.

[0119] In this step, manually or by a manipulator, remove the processed bottom steel bar 100 from the steel bar arc bending device 1 and place it in the storage area.

[0120] S18. Load the next batch of steel bars 100 from the feeding side and convey them to the side of the two traction wheels 12 facing the arc bending pressure wheel 15.

[0121] In this step, gradually insert the steel bar 100 from the feeding side between the traction wheel 12 and the arc bending pressure wheel 15, and then the traction driver can drive the traction wheel 12 to rotate, so that the steel bar 100 can be input more efficiently.

[0122] After that, repeat S1 - S17 to process the steel bar 100.
