[0012] In one embodiment of the present application, the first transmission mechanism includes a first transmission wheel, a first transmission belt, a second transmission wheel, a first meshing gear and a fixed shaft, wherein the first transmission wheel is arranged on the rotating shaft; one end of the first transmission belt is sleeved on the first transmission wheel, and the other end of the first transmission belt is sleeved on the second transmission wheel; the second transmission wheel and the first meshing gear are respectively arranged on the fixed shaft; and the fixed shaft is rotatably arranged on the supporting box body.

[0013] In one embodiment of the present application, the second transmission mechanism includes a second meshing gear, a connecting shaft, a third transmission wheel, a second transmission belt and a fourth transmission wheel, wherein the second meshing gear is meshed with the first meshing gear, and the second meshing gear is arranged inside the supporting box; the connecting shaft is rotatably arranged on the supporting box, one end of the connecting shaft is connected to the second meshing gear, and the other end of the connecting shaft is connected to the third transmission wheel; the third transmission wheel is arranged outside the supporting box; one end of the second transmission belt is sleeved on the third transmission wheel, and the other end of the second transmission belt is sleeved on the fourth transmission wheel; the fourth transmission wheel is connected to the blanking assembly.

[0014] In one embodiment of the present application, a material unloading assembly includes a material unloading box, a partition plate and a rotating material unloading roller, wherein the material unloading box is arranged on a supporting box, a material unloading port is provided at the bottom of the material unloading box, and the material unloading port is located above a receiving plate and a one-way rotating clamping member; the partition plates are respectively arranged in the material unloading box, and a steel pipe passage is provided between the partition plates; the rotating material unloading roller is provided with a transmission shaft, the transmission shaft is rotatably connected to the material unloading box, and one end of the transmission shaft is connected to the material unloading linkage control mechanism; the rotating material unloading roller is provided with a steel pipe placement groove, and the steel pipe placement groove is rotatably connected to the steel pipe passage and the material unloading port, respectively.

[0016] The beneficial effects of this application are as follows:

[0017] Through the two partition plates arranged in the unloading box, the steel pipe passage formed between the two partition plates can only pass a single steel pipe. When the steel pipe placing groove on the rotating unloading roller is connected with the steel pipe passage, the single steel pipe enters the steel pipe placing groove, and when the unloading roller is rotated to rotate the steel pipe placing groove to the unloading port, the single steel pipe is unloaded onto the receiving plate, thereby realizing the loading of steel pipes one by one, ensuring the continuous loading of steel pipes, and improving the bending efficiency of steel pipes.

By controlling the up and down movement of the elastic rod, the unidirectional rotating clamping member on the elastic rod is driven to move up and down, and cooperates with the first clamping member to clamp or loosen the steel pipe. By controlling the long-distance parallel movement of the feeding rod, the clamped steel pipe can be driven to move in the direction of the angle control mechanism, thereby realizing continuous feeding of the steel pipe.

[0033] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0034] The steel pipe bending device according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0035] like Figure 1-Figure 10 As shown, the steel pipe bending device of the embodiment of the present application may include a supporting box 1, a material unloading component 2, a material receiving plate 3, a motor 4, a material unloading linkage control mechanism 5, a clamping and feeding mechanism 6, an angle control mechanism 7 and a bending mechanism 8.

[0036] A support plate 13 is slidably disposed on the support box 1 , and a first through hole 10 and a second through hole 11 are opened on the support box 1 .

[0037] It should be noted that the support box 1 described in this embodiment is provided with a first electrically controlled slide rail 15 , and the support plate 13 is slidably connected to the first electrically controlled slide rail 15 , thereby realizing a slidable connection between the support plate 13 and the support box 1 .

[0038] The blanking assembly 2 is arranged on one side of the supporting box 1 .

[0039] In the embodiment of the present application, the blanking assembly 2 is used to blank the steel pipes one by one in sequence, thereby ensuring the continuity of the steel pipe blanking and improving the steel pipe bending efficiency.

[0040] The receiving plate 3 is rotatably disposed on the supporting box 1 and is located at the bottom of the blanking assembly 2 , and the third through hole 30 formed on the receiving plate 3 is disposed correspondingly to the second through hole 11 up and down.

[0041] In the embodiment of the present application, the receiving plate 3 limits the position of the steel pipe discharged from the discharge assembly 2, thereby facilitating the feeding of the clamping feeding mechanism 6.

[0042] It should be noted that the receiving plate 3 is an arc-shaped plate, which makes it convenient to limit the steel pipes being cut onto the receiving plate 3. In addition, the receiving plate 3 rotates on the supporting box 1 in a small arc, so that after the angle control mechanism 7 clamps the steel pipe and moves to the side of the bending mechanism 8, the steel pipe drives one side of the receiving plate 3 to flip in a small arc, thereby realizing the cutting of the steel pipes onto the receiving plate 3, and the small arc rotation of the receiving plate 3 on the supporting box 1 will not affect the limiting effect of the receiving plate 3 on the steel pipes.

[0043] The motor 4 is arranged in the supporting box 1 , and a rotating shaft 40 is arranged on the output shaft of the motor 4 . One end of the material unloading joint control mechanism 5 is connected to the rotating shaft 40 , and the other end of the material unloading joint control mechanism 5 is connected to the material unloading component 2 .

[0044] In the embodiment of the present application, the unloading joint control mechanism 5 is used to connect the motor 4 and the unloading component 2. The rotation of the motor 4 can drive the unloading joint control mechanism 5 to rotate, thereby driving the unloading component 2 to unload the steel pipes one by one, thereby reducing the use of components such as the motor 4 and sensors, and reducing the use cost of the device.

[0045] The clamping and feeding mechanism 6 may include a fixing rod 60 , a feeding rod 61 , a rotation control member 62 , an elastic rod 63 and a one-way rotating clamping member 64 .

[0046] In the embodiment of the present application, the clamping and feeding mechanism 6 is used to limit the clamping of the steel pipe and move the steel pipe to the angle control mechanism 7 so that the angle control mechanism 7 limits the clamping of the steel pipe.

[0047] The fixing rod 60 is fixedly arranged in the supporting box 1 .

[0048] It should be noted that two limit blocks 600 can be set on the fixed rod 60 described in this embodiment, and the distance between the two limit blocks 600 corresponds to the distance the steel pipe needs to be transported, thereby ensuring that the steel pipe is effectively transported to the angle control mechanism 7 and enabling the angle control mechanism 7 to clamp the steel pipe.

[0049] One end of the feeding rod 61 is slidably connected to the fixing rod 60 . A first clamping block 610 is provided on the feeding rod 61 . The first clamping block 610 passes through the second through hole 11 and is slidably connected to the third through hole 30 .

[0050] It should be noted that the first clamping block 610 described in this embodiment protrudes from the outside of the third through hole 30, that is, the first clamping block 610 protrudes from the top surface of the receiving plate 3, thereby facilitating the one-way rotating clamping member 64 and the first clamping block 610 to clamp the steel pipe and ensure the clamping and feeding effect of the steel pipe.

[0051] One end of the rotation control member 62 is fixedly connected to the rotation shaft 40 , and the other end of the rotation control member 62 is slidably connected to the feeding rod 61 .

[0052] In the embodiment of the present application, the rotation control member 62 is used to convert the circular rotation of the rotating shaft 40 into a rectangular rotation (that is, the motor 4 rotates, the output shaft of the motor 4 rotates in a circle, driving the rotating shaft 40 to rotate in a circle, and the rotating shaft 40 drives the connecting block 620 provided at one end of the rotation control member 62 to rotate in a circle, and the sliding control block 624 provided at the other end of the rotation control member 62 is slidably connected to the feeding rod 61, and the sliding control block 624 performs a linear motion in the up and down directions on the feeding rod 61 under the sliding limit of the feeding rod 61, thereby forming a wide side of the rectangular rotation, the motor 4 continues to rotate, and after the sliding control block 624 slides to the bottom of the feeding rod 61, the sliding control block 624 drives the feeding rod 61 to move linearly in the left and right directions on the fixed rod 60 Linear motion, thereby forming a long side of the rectangular rotation, and under the continued rotation of the motor 4, repeat the above operation to form the other wide side and the other long side of the rectangular rotation, so that the rotation control member 62 converts the circular rotation of the rotating shaft 40 into a rectangular rotation), so as to facilitate the long-distance parallel movement control of the feeding rod 61 and the up and down movement control of the elastic rod 63. By controlling the up and down movement of the elastic rod 63, the one-way rotating clamping member 64 on the elastic rod 63 is driven to move up and down, and cooperate with the first clamping block 610 to clamp or loosen the steel pipe. By controlling the long-distance parallel movement of the feeding rod 61, the clamped steel pipe can be driven to move in the direction of the angle control mechanism 7, thereby realizing continuous feeding of the steel pipe.

[0053] It should be noted that the length of the feeding rod 61 described in this embodiment is greater than the sliding stroke of the rotating control member 62 on the feeding rod 61 , thereby preventing the rotating control member 62 from sliding out of the feeding rod 61 .

[0054] One end of the elastic rod 63 is connected to the rotation control member 62 , and the other end of the elastic rod 63 passes through the first through hole 10 and is connected to the one-way rotation clamping member 64 . The one-way rotation clamping member 64 is arranged above the first clamping block 610 .

[0055] In the embodiment of the present application, the one-way rotating clamping part 64 refers to the part that only performs elastic rotation in one direction, that is, the one-way rotating clamping part 64 can be elastically bent (and restore to the initial unbent state after bending) when the steel pipe is loaded and unloaded from the one-way rotating clamping part 64, so that the steel pipe is unloaded from the one-way rotating clamping part 64 to the receiving plate 3. When the one-way rotating clamping part 64 is pressed down to clamp the steel pipe, the one-way rotating clamping part 64 will not bend, thereby cooperating with the first clamping block 610 to limit the clamping of the steel pipe.

[0056] It should be noted that the one-way rotating clamping member 64 described in this embodiment is smaller in size and has a relatively smaller elastic deformation recovery force than the steel pipe, so it has less impact on the unloading of the steel pipe. That is, when the steel pipe is unloaded to the one-way rotating clamping member 64, the steel pipe will still be unloaded to the receiving plate 3 after being blocked by the one-way clamping member, thereby ensuring the unloading effect of the steel pipe.

[0057] It is understandable that the elastic rod 63 is a common elastic telescopic rod on the market. The provision of the elastic rod 63 facilitates adjustment of the length of the steel pipe by the one-way rotating clamping member 64 to press down and clamp it.

[0058] It can be understood that the motor 4 drives the rotating shaft 40 to rotate, and drives the rotating control member 62 to rotate, and the rotating control member 62 is slidably connected with the feeding rod 61, so that when the rotating control member 62 rotates in a rectangular shape, it first slides from top to bottom on the feeding rod 61, and the rotating control member 62 slides downward to drive the elastic rod 63 to move downward, so that the one-way rotating clamping member 64 and the first clamping block 610 are clamped together to clamp the steel pipe. The motor 4 continues to drive the rotating shaft 40 to rotate in a circle, and drives one end of the rotating control member 62 to slide to the bottom of the feeding rod 61 and then continue to rotate, so as to control the translation of the bottom of the feeding rod 61, so that the top of the feeding rod 61 slides parallel to the fixed rod 60, and drives the first clamping block 610 on the feeding rod 61 and the one-way rotating clamping member 64 on the elastic rod 63 to move parallel, so as to transport the steel pipe to the angle control mechanism 7, so that the angle control mechanism 7 clamps the steel pipe.

[0059] The angle control mechanism 7 is slidably disposed on the support plate 13 .

[0060] It should be noted that the support plate 13 described in this embodiment is provided with a second electrically controlled slide rail 130 , and the angle control mechanism 7 is slidably connected to the second electrically controlled slide rail 130 , thereby realizing a slidable connection between the angle control mechanism 7 and the support plate 13 .

[0061] It can be understood that the controller (not shown in the figure) controls the first electrically-controlled slide rail 15 to make the support plate 13 slide on the support box 1, thereby driving the steel pipe clamped on the angle control mechanism 7 to move from the receiving plate 3 to the side of the bending mechanism 8. The controller controls the second electrically-controlled slide rail 130 to make the angle control mechanism 7 slide on the support plate 13, and can drive the steel pipe clamped on the angle control mechanism 7 to feed to the bending mechanism 8, so that the bending mechanism 8 bends the steel pipe, ensuring the continuous feeding of the steel pipe and improving the bending efficiency of the steel pipe.

[0062] It should be noted that the angle control mechanism 7 described in this embodiment is a common component in steel pipe bending devices on the market, which can clamp and feed steel pipes and rotate the steel pipes at different angles, so that the steel pipes can be bent at different angles.

[0063] The bending mechanism 8 is arranged on one side of the supporting box 1 .

[0064] It should be noted that the bending mechanism 8 described in this embodiment is a common component in steel pipe bending devices on the market, and its main function is to effectively bend the steel pipe, which will not be described in detail here.

[0065] Specifically, in the actual operation process, the relevant staff puts multiple steel pipes into the unloading component 2 respectively, and starts the device. The controller controls the motor 4 to rotate, drives the rotating shaft 40 to rotate, and drives one end of the unloading linkage control mechanism 5 to rotate. The other end of the unloading linkage drives the unloading component 2 to do work, thereby unloading the steel pipes in the unloading component 2 one by one. The steel pipe is unloaded from the unloading component 2 to the one-way rotating clamping piece 64. Due to the gravity of the steel pipe, the one-way rotating clamping piece 64 is bent, so that the steel pipe is unloaded through the one-way rotating clamping piece 64 to the receiving plate 3 and abuts against the first clamping block 610.

[0066] In addition, when the rotating shaft 40 rotates, it can drive the rotating control member 62 to rotate. One end of the rotating control member 62 slides on the top of the feeding rod 61, and drives the feeding rod 61 to slide from the middle of the fixed rod 60 to the limit block 600 on one side of the fixed rod 60. At this time, the steel pipe is unloaded from the unloading assembly 2 to the receiving plate 3 under the control of the unloading linkage control mechanism 5, and abuts against the first clamping block 610. The motor 4 continues to rotate, driving the rotating control member 62 to continue to rotate. One end of the rotating control member 62 slides from the top of the feeding rod 61 to the bottom of the feeding rod 61. In the process of sliding from the top of the feeding rod 61 to the bottom of the feeding rod 61, one end of the rotating control member 62 drives the elastic rod 63 to move downward. The elastic rod 63 drives the unidirectional rotating clamping member 64 to move downward, and cooperates with the first clamping block 610 to clamp the steel pipe.

[0067] The rotating control member 62 continues to rotate, and one end of the rotating control member 62 slides at the bottom of the feeding rod 61, and drives the feeding rod 61 to slide toward the limit block 600 on the other side of the fixed rod 60, and during the movement, the unidirectional rotating clamping member 64 and the first clamping block 610 continue to clamp the steel pipe, so that the steel pipe slides on the receiving plate 3 toward the angle control mechanism 7 and is clamped by the clamping component of the angle control mechanism 7 (not shown in the figure). The rotating control member 62 continues to rotate, so that one end of the rotating control member 62 moves from the bottom of the feeding rod 61 to the top of the feeding rod 61, and in the process of sliding from the bottom of the feeding rod 61 to the top of the feeding rod 61, the elastic rod 63 and the one-way rotating clamping member 64 are driven to move upward, thereby releasing the clamping of the steel pipe. As the rotating control component continues to rotate, one end of the rotating control component controls the feeding rod 61 to slide on the fixed rod 60 to the initial position, and the controller controls the motor 4 to stop rotating. After the steel pipe is bent, when the angle control mechanism 7 returns to the initial position, the above operation is repeated.

[0068] After the steel pipe is released from clamping, the controller controls the support plate 13 to slide on the first electric-controlled slide rail 15, and slides to one side of the bending mechanism 8, and continues to control the angle control mechanism 7 to slide on the second electric slide rail, and feeds the clamped steel pipe to the bending mechanism 8 for bending, and according to the shape of the steel pipe, the angle control mechanism 7 rotates the steel pipe so that the bending mechanism 8 bends the steel pipe into a corresponding shape, thereby completing the bending of the steel pipe and improving the bending efficiency of the steel pipe.

[0069] In one embodiment of the present application, Figure 6 , Figure 8 and Fig. 9 As shown, the rotation control member 62 may include a connecting block 620 , a rotation rod 621 , a first spring 622 , a rotation control block 623 and a sliding control block 624 .

[0070] Among them, the connecting block 620 is fixedly connected to the rotating shaft 40, the rotating rod 621 is slidably connected to the connecting block 620, and one end of the rotating rod 621 is fixedly connected to the rotating control block 623, and the other end of the rotating rod 621 extends to the outside of the connecting block 620, the first spring 622 is sleeved on the rotating rod 621, one end of the first spring 622 is connected to the rotating control block 623, and the other end of the first spring 622 is connected to the connecting block 620, one end of the sliding control block 624 is rotatably connected to the rotating control block 623, the other end of the sliding control block 624 is fixedly connected to the elastic rod 63, and the sliding control block 624 is slidably connected to the feeding rod 61.

[0071] It should be noted that the rotating rod 621 described in this embodiment will not slide away from the connecting block 620 , thereby ensuring the control effect of the rotating control member 62 .

[0072] It can be understood that, by setting the first spring 622, the rotating rod 621 can slide and retract on the connecting block 620 according to the elastic deformation of the spring, so that the sliding distance of the rotating rod 621 on the feeding rod 61 can be extended and compensated (for example, in the process of the rotating rod 621 rotating to the top or bottom of the feeding rod 61, the first spring 622 restores the elastic deformation, pushes the rotating control block 623 to extend, and drives the rotating rod 621 to extend, thereby performing extension compensation), thereby converting the circular rotation of the rotating shaft 40 into the rectangular rotation of the rotating control block 623 (the rectangular rotation is as shown in FIG. Fig.10 As shown, the rectangular motion trajectory of the rotation control block 623 represented by multiple arrows ensures the continuous clamping of the steel pipe by the unidirectional rotating clamping member 64 and the long-distance transportation of the steel pipe by the feeding rod 61.

[0073] In one embodiment of the present application, Figure 6 , Figure 8 and Fig. 9 As shown, the one-way rotating clamping member 64 may include a connecting seat 640 , a second spring 641 and a second clamping block 642 .

[0074] Among them, one end of the connecting seat 640 is connected to the elastic rod 63, the other end of the connecting seat 640 is rotatably connected to the bottom of the second clamping block 642, one end of the second spring 641 is connected to the connecting seat 640, and the other end of the second spring 641 is connected to the second clamping block 642.

[0075] It can be understood that by rotatably connecting the connecting seat 640 with the bottom of the second clamping block 642, when the second clamping block 642 clamps the steel pipe, the top of the second clamping block 642 abuts against the corresponding top of the connecting seat 640, thereby realizing the unidirectional rotation of the unidirectional rotating clamping member 64, realizing the passage of the steel pipe and the clamping of the steel pipe feeding.

[0076] It can be understood that, through the setting of the second spring 641, after the steel pipe passes through the bent second clamping block 642, the second clamping block 642 returns to its initial position under the recovery of the elastic deformation of the second spring 641, thereby facilitating the second clamping block 642 to clamp the steel pipe.

[0077] In one embodiment of the present application, Figure 5-Figure 7 As shown, the material unloading linkage control mechanism 5 may include a first transmission mechanism 50 and a second transmission mechanism 51 .

[0078] One end of the first transmission mechanism 50 is connected to the rotating shaft 40 , one end of the second transmission mechanism 51 is connected to the first transmission mechanism 50 , and the other end of the second transmission mechanism 51 is connected to the blanking assembly 2 .

[0079] It can be understood that, by setting the second transmission mechanism 51 , the transmission direction of the first transmission mechanism 50 can be changed, thereby ensuring the linkage control of the motor 4 on the blanking component 2 .

[0080] In one embodiment of the present application, Figure 1 and Figure 5-Figure 7 As shown, the first transmission mechanism 50 may include a first transmission wheel 500 , a first transmission belt 501 , a second transmission wheel 502 , a first meshing gear 503 and a fixed shaft 504 .

[0081] Among them, the first transmission wheel 500 is set on the rotating shaft 40, one end of the first transmission belt 501 is sleeved on the first transmission wheel 500, and the other end of the first transmission belt 501 is sleeved on the second transmission wheel 502, the second transmission wheel 502 and the first meshing gear 503 are respectively set on the fixed shaft 504, and the fixed shaft 504 is rotatably set on the supporting box 1.

[0082] It can be understood that the first transmission mechanism 50 is arranged in the supporting box 1, and through the connection between the first transmission wheel 500 and the rotating shaft 40, the motor 4 drives the rotating shaft 40 and the first transmission mechanism 50, thereby reducing the use of the motor 4 and reducing the use cost of the device.

[0083] In one embodiment of the present application, Figure 1 and Figure 5-Figure 7 As shown, the second transmission mechanism 51 may include a second meshing gear 510 , a connecting shaft 511 , a third transmission wheel 512 , a second transmission belt 513 and a fourth transmission wheel 514 .

[0084] Among them, the second meshing gear 510 is meshed with the first meshing gear 503, the second meshing gear 510 is arranged inside the supporting box body 1, the connecting shaft 511 is rotatably arranged on the supporting box body 1, one end of the connecting shaft 511 is connected to the second meshing gear 510, and the other end of the connecting shaft 511 is connected to the third transmission wheel 512, the third transmission wheel 512 is arranged outside the supporting box body 1, one end of the second transmission belt 513 is sleeved on the third transmission wheel 512, and the other end of the second transmission belt 513 is sleeved on the fourth transmission wheel 514, and the fourth transmission wheel 514 is connected to the unloading component 2.

[0085] It should be noted that the connecting shaft 511 described in this embodiment is rotatably connected to the supporting box body 1, one end of the connecting shaft 511 is located inside the supporting box body 1, and is connected to the second meshing gear 510, the other end of the connecting shaft 511 is located outside the supporting box body 1, and is connected to the third transmission wheel 512, and the fourth transmission wheel 514 is connected to the rotating unloading roller 22 through the transmission shaft 221 on the unloading assembly 2, so that the motor 4 is linked to control the rotating unloading roller 22, thereby reducing the use cost of the device.

[0086] In one embodiment of the present application, Figure 1 , Figure 2 and Figure 4 As shown, the unloading assembly 2 may include an unloading box 20 , a partition plate 21 and a rotating unloading roller 22 .

[0087] Among them, the unloading box 20 is arranged on the supporting box 1, and a unloading port 200 is opened at the bottom of the unloading box 20, and the unloading port 200 is located above the receiving plate 3 and the one-way rotating clamping member 64. The partition plates 21 are respectively arranged in the unloading box 20, and a steel pipe inlet is arranged between the partition plates 21. The rotating unloading roller 22 is provided with a transmission shaft 221, and the transmission shaft 221 is rotatably connected to the unloading box 20, and one end of the transmission shaft 221 is connected to the unloading linkage control mechanism 5. The rotating unloading roller 22 is opened with a steel pipe placing groove 220, and the steel pipe placing groove 220 is respectively rotatably connected with the steel pipe inlet and the unloading port 200.

[0088] It should be noted that the steel pipes in the unloading box 20 described in this embodiment are arranged neatly, and the ports at both ends of the steel pipes are parallel to the ports at both ends of the receiving plate 3, so as to facilitate the loading of the steel pipes.

[0089] It can be understood that the steel pipe inlet can only pass a single steel pipe. When the steel pipe placing groove 220 on the rotating unloading roller 22 is connected to the steel pipe inlet, the single steel pipe enters the steel pipe placing groove 220, and when the rotating unloading roller 22 rotates the steel pipe placing groove 220 to the unloading port 200, the single steel pipe is unloaded onto the receiving plate 3, thereby realizing the one-by-one loading of the steel pipes, ensuring the continuous loading of the steel pipes, and improving the bending efficiency of the steel pipes.

[0090] In one embodiment of the present application, Figure 3 and Fig. 9 As shown, a first material baffle plate 14 is provided on the supporting box body 1 , and the first material baffle plate 14 is provided on a side of the receiving plate 3 away from the elastic rod 63 , and a second material baffle plate 31 is provided on a side of the receiving plate 3 close to the elastic rod 63 .

[0091] It can be understood that, by setting the first baffle plate and the second baffle plate, it is further ensured that the steel pipe is stably fed to the receiving plate 3 during the process of being blocked by the second clamping block 642 for feeding.

[0092] Specifically, in the actual operation process, the relevant staff debugs the device, puts a plurality of steel pipes into the unloading box 20 respectively, and starts the device. The controller controls the motor 4 to rotate, drives the rotating shaft 40 to rotate, and drives the first transmission wheel 500 to rotate. The first transmission wheel 500 drives the second transmission wheel 502 to rotate through the first transmission belt 501, and drives the fixed shaft 504 to rotate on the supporting box 1, thereby driving the first meshing gear 503 to rotate. The first meshing gear 503 drives the second meshing gear 510 and the connecting shaft 511 to rotate, and drives the third The transmission wheel 512 rotates, and the third transmission wheel 512 drives the fourth transmission wheel 514 to rotate through the second transmission belt 513. The fourth transmission wheel 514 drives the rotating unloading roller 22 to rotate through the transmission shaft 221, so that a single steel pipe is unloaded from the steel pipe inlet hole to the steel pipe placement groove 220, and is rotated to the unloading port 200 by rotating the unloading roller 22. The steel pipe is bent by the gravity of the steel pipe through the second clamping block 642, so that the steel pipe is unloaded to the receiving plate 3 and abuts against the first clamping block 610, thereby realizing the unloading of the steel pipes in the unloading component 2 one by one, ensuring the continuity of steel pipe loading.

[0093] In addition, when the rotating shaft 40 rotates, it can drive the connecting block 620 to rotate, thereby driving the rotating rod 621 and the rotating control block 623 to rotate. The rotating control block 623 rotates to control the sliding block 624 to slide on the top of the feeding rod 61, and drives the feeding rod 61 to slide from the middle of the fixed rod 60 to the limit block 600 on one side of the fixed rod 60. At this time, the steel pipe is unloaded from the unloading box 20 to the receiving plate 3 under the control of the unloading linkage control mechanism 5, and abuts against the first clamping block 610. The motor 4 continues to rotate, driving the rotating control member 62 to continue to rotate, and the sliding block 624 slides from the top of the feeding rod 61 to the bottom of the feeding rod 61. In the process of sliding from the top of the feeding rod 61 to the bottom of the feeding rod 61, the sliding block 624 drives the elastic rod 63 to move downward, and the elastic rod 63 drives the one-way rotating clamping member 64 to move downward, and makes the second clamping block 642 cooperate with the first clamping block 610, thereby clamping the steel pipe.

[0094] The rotating control member 62 continues to rotate, and the sliding control block 624 slides at the bottom of the feeding rod 61, and drives the feeding rod 61 to slide toward the limit block 600 on the other side of the fixed rod 60, and during the movement, the second clamping block 642 and the first clamping block 610 continue to clamp the steel pipe, so that the steel pipe slides toward the angle control mechanism 7 on the receiving plate 3 and is clamped by the clamping component of the angle control mechanism 7 (not shown in the figure). The rotating control member 62 continues to rotate, causing the sliding block 624 to move from the bottom of the feeding rod 61 to the top of the feeding rod 61, and in the process of sliding from the bottom of the feeding rod 61 to the top of the feeding rod 61, the elastic rod 63 and the one-way rotating clamping member 64 are driven to move upward, so that the second clamping block 642 and the first clamping block 610 are separated, thereby releasing the clamping of the steel pipe. With the continued rotation of the rotating control member 62, the sliding block 624 controls the feeding rod 61 to slide on the fixed rod 60 to the initial position, and drives the elastic rod 63 and the one-way rotating clamping member 64 to return to the initial position. At this time, the controller controls the motor 4 to stop rotating. After the steel pipe is bent, when the angle control mechanism 7 returns to the initial position, the above operation is repeated.

[0095] After the steel pipe is released from clamping, the controller controls the support plate 13 to slide on the first electric-controlled slide rail 15, and slides to one side of the bending mechanism 8, and continues to control the angle control mechanism 7 to slide on the second electric slide rail, and feeds the clamped steel pipe to the bending mechanism 8 for bending, and according to the shape of the steel pipe, the angle control mechanism 7 rotates the steel pipe so that the bending mechanism 8 bends a steel pipe of a corresponding shape, thereby completing the bending of the steel pipe. After the steel pipe is unloaded, the controller controls the bending mechanism 8 and the angle control mechanism 7 to return to the initial position, and repeats the above operations, thereby realizing continuous feeding and continuous bending of the steel pipe, thereby improving the bending efficiency of the steel pipe.

[0096] The steel pipe bending device provided in the embodiment of the present application can be applied to fields such as construction engineering and manufacturing. In construction engineering, steel pipe bending is used to make handrails, railings, stairs and structural supports. In the manufacturing industry, the bent steel pipes can be used to produce pipes, frames and mechanical parts. Especially in the electric vehicle industry, it is used to manufacture handlebars, frames and anti-collision frames on electric vehicles. It can continuously feed steel pipes, thereby improving the bending efficiency of steel pipes.

[0097] In summary, the steel pipe bending device of the embodiment of the present application can continuously feed steel pipes, thereby reducing the labor intensity of relevant personnel and improving the bending efficiency of steel pipes.
