Description

Technical Field

[0001] The invention relates to the field of angle steel processing accessories, and in particular to an angle steel bending device. Background Art

[0002] Angle steel is an important component for manufacturing iron towers. Since the current iron towers are roughly conical, some of the angle steels used in the current iron towers need to be bent. In order to be able to bend the angle steels, the patent announcement document CN219541409U discloses a device that can bend angle steels. This device that can bend angle steels mainly has two cylinders (respectively a clamping cylinder and a bending cylinder, and the figure marking serial numbers in the document are 6 and 10 respectively) to bend the angle steel. Since two cylinders are needed in this bending process, the use of two cylinders will not only reduce the reliability of the entire equipment during bending, but also increase the error between the angle steel parts after bending. Summary of the invention

[0003] In view of the above-mentioned problems, the present invention proposes an angle steel bending device, in which a lifting head is only used for installing the press plate. When the lifting head is running, the press plate moves closer to or away from the bottom plate. Only one lifting head is required to complete the extrusion bending process during the entire bending process. The entire extrusion bending process is reliable, and the error between the angle steel parts after extrusion bending is relatively smaller.

[0004] The technical solution adopted by the present invention is as follows:

[0005] An angle steel bending device includes a base, a lifting head, a bottom template and a pressing template, the lifting head is arranged on the base, the bottom template is arranged on the base, the pressing template is arranged on the lifting head, the bottom template is provided with a first supporting groove and a second supporting groove, so the first supporting groove and the second supporting groove are not on the same plane, the pressing template is provided with a first extrusion protrusion and a second extrusion protrusion, and the first extrusion protrusion and the second extrusion protrusion are not on a straight line.

[0006] The working process of the angle steel bending device is as follows: first, the angle steel to be bent is placed on the bottom template, and then the lifting head drives the pressing template to move toward the bottom template, and the angle steel is bent under the extrusion of the bottom template and the pressing template, thereby completing the bending process of the angle steel. After the angle steel is bent, the first supporting groove, the second supporting groove, the first extrusion protrusion and the second extrusion protrusion are close to the angle steel.

[0007] Specifically in this bending device, the lifting head can be a hydraulic lifting head or an electric lifting head.

[0008] In summary, in this angle steel bending device, only the lifting head is installed on the press plate. When the lifting head is running, the press plate moves closer to or away from the bottom plate. Only one lifting head is required to complete the extrusion bending process during the entire bending process. The entire extrusion bending process is reliable, and the error between the angle steel parts is relatively smaller after extrusion bending.

[0009] Optionally, it also includes an electric heating sleeve, which is arranged on one side of the base.

[0010] The electric heating sleeve adopts industrial frequency alternating current. After the electric heating sleeve heats the angle steel, the angle steel is placed on the bottom template. The angle steel is then squeezed and bent by the bottom template and the pressure template, and the entire bending process is finally completed.

[0011] Specifically, this type of electric heating sleeve is a right-angle electric heating sleeve, and the angle steel can pass between the electric heating sleeves before being bent.

[0012] Optionally, it also includes a conveying frame and a pushing frame. The conveying frame is arranged on one side of the electric heating sleeve. A guide rail is arranged on one side of the conveying frame. A rack is arranged on one side of the guide rail. The rack and the guide rail are in a parallel state. The pushing frame and the guide rail are slidably matched together. The pushing frame is provided with a pushing motor. The shaft of the pushing motor is matched with the rack through a gear.

[0013] The specific function of the conveying frame is to guide and clamp the angle steel. When the angle steel is subjected to external force, the angle steel can move on the conveying frame. When pushed by external force, the angle steel can enter the electric heating sleeve for heating. After the heating is completed, it can also be moved out of the conveying frame through the conveying frame under the action of external force. At the same time, in this bending device, a guide rail is set on one side of the conveying frame, and a rack parallel to the guide rail is set on one side of the guide rail. The pushing frame is slidably installed on the guide rail, and a pushing motor is set on the pushing frame. The shaft of the pushing motor is meshed with the rack through the gear. When the pushing motor is running, the pushing frame slides along the guide rail. When the pushing frame slides, it can push the angle steel on the conveying frame to move on the conveying frame. When the angle steel slides on the sliding frame, it can slide into the electric heating sleeve or slide out of the electric heating sleeve.

[0014] The specific conveying frame includes a base plate and a plurality of supporting rollers. The base plate is an isosceles trapezoidal base plate. Supporting rollers are rotatably installed at both ends of the base plate. The supporting rollers are in a rotatable state relative to the base plate. The supporting rollers are used to contact the outer wall surface of the angle steel. The rotation of the supporting rollers can allow the angle steel to slide relative to the base plate.

[0015] Specifically in this device, in order to be able to stably push the angle steel to move on the conveying frame, two tensioning hooks and a clamping cylinder are further arranged on the pushing frame. The two tensioning hooks are rotatably installed on the pushing frame, and the other ends of the two tensioning hooks are matched with the clamping cylinder. When the cylinder rod of the clamping cylinder contracts, the two tensioning hooks move closer to each other, and the two tensioning hooks can clamp the angle steel when they move closer. When the cylinder rod of the clamping cylinder extends, the two tensioning hooks extend, and the two tensioning hooks no longer clamp the angle steel.

[0016] When the two tensioning hooks clamp the angle steel, the pushing frame can move back and forth stably on the conveying frame with the angle steel.

[0017] Specifically, this type of device also includes a plurality of lifting cylinders, which are fixedly installed on a frame. The frame is set on one side of the base, and the guide rails and racks are also installed on the frame. There are multiple conveyor racks in this device, some of which are fixedly installed on the frame, and the other conveyor racks are installed on the cylinder rods of the lifting cylinders. When the cylinder rods of the lifting cylinders are extended or retracted, the conveyor racks are lifted or lowered relative to the frames. When the cylinder rods of the lifting cylinders are extended, all the conveyor racks are arranged together to form a complete conveyor belt, which can continuously and stably convey the angle steel. When the cylinder rods of the lifting cylinders are retracted, all the conveyor racks no longer form a complete conveyor belt, and an avoidance gap is formed on the conveyor belt. The existence of the avoidance gap facilitates the clamping operation of the angle steel by the gripper on the robot arm, ensuring that the gripper has good clamping efficiency for the angle steel.

[0018] Optionally, it also includes a mechanical arm and a clamping claw, wherein the clamping claw is arranged on the mechanical arm, and the mechanical arm is arranged on one side of the base.

[0019] The specific clamping claw is installed on the mechanical arm, and the clamping claw is used to clamp the angle steel, while the function of the mechanical arm is to transport the angle steel after clamping the angle steel.

[0020] The specific clamping claw includes a clamping seat, an electromagnetic adsorption claw and a suspension clamp. The electromagnetic adsorption claw is installed on the clamping seat. The electromagnetic adsorption claw directly uses magnetic attraction to adsorb and clamp the angle steel. Before the angle steel is heated by the electric heating sleeve, the angle steel can be clamped by the electromagnetic adsorption claw. A slide rail is also installed in the specific clamping seat. There are two suspension clamps. The two suspension clamps are slidably installed on the slide rails respectively. An adjusting screw is rotatably installed in the clamping seat. The adjusting screw and the slide rail are in a parallel and non-contact state. The two ends of the adjusting screw are respectively matched with the two suspension clamps by threaded matching. The clamping seat is installed with an adjusting motor. The shaft of the adjusting motor is matched with the adjusting screw by a coupling. The two suspension clamps are located on both sides of the coupling. When the adjusting motor rotates, the two suspension clamps move closer to each other or away from each other, thereby realizing the adjustable distance installation of the suspension clamp, ensuring that the suspension clamp can stably clamp the suspension angle steel.

[0021] Optionally, a lifting garage is also included, and the lifting garage is arranged on one side of the base platform.

[0022] The function of the lifting warehouse is to act as a warehouse. The lifting warehouse can be used to store angle steels before and after bending.

[0023] Optionally, a temporary storage table is also included. The temporary storage table is arranged on one side of the base platform. A rotating seat is arranged on one side of the temporary storage table. A supporting arm is arranged on the rotating axis of the rotating seat, and an electromagnetic magnet is arranged on the supporting arm.

[0024] The specific temporary storage table is also located on one side of the conveyor frame. The functions of the rotating seat, the supporting arm and the electromagnetic magnet are to adsorb and reverse the angle steel, and the function of the temporary storage table is to place the reversed angle steel. The specific whole process is as follows: first, the angle steel on the conveyor frame is in a state of opening upwards, at this time, the rotating shaft rotates, so that the electromagnetic magnet on the supporting arm attracts the angle steel, and then the rotating shaft rotates in the opposite direction, and the reverse rotation of the rotating shaft drives the supporting arm to rotate in the opposite direction. After the supporting arm rotates in the opposite direction, the angle steel will reach the temporary storage table. When the angle steel contacts the temporary storage table, the electromagnetic magnet no longer attracts the angle steel. After the electromagnetic magnet releases the angle steel, the rotating shaft drives the supporting arm to rotate again.

[0025] Optionally, a supporting platform is also included, and the supporting platform is arranged on the periphery of the base.

[0026] The function of the support platform is to temporarily place the angle steel before bending and the angle steel after bending.

[0027] Optionally, a support plate is provided on the supporting platform.

[0028] The specific function of the pedestal is to place the angle steel. The pedestal is placed directly on the supporting platform, and the pedestal can be transferred between the supporting platform and the lifting warehouse.

[0029] The angle steel on the specific tray can be moved to the temporary storage table by the clamp and the robot arm for temporary storage.

[0030] The beneficial effects of the present invention are as follows: only the lifting head is installed on the press plate, and when the lifting head is running, the press plate moves closer to or away from the bottom plate, and only one lifting head is operated during the entire bending process to complete the extrusion bending process. The entire extrusion bending process is reliable, and the error between the angle steel parts after extrusion bending is relatively smaller. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0043] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0045] As attached Figure 1 ~Attached Fig. 9 As shown, an angle steel bending device includes a base 1, a lifting head 2, a bottom template 3 and a pressing template 4, the lifting head 2 is arranged on the base 1, the bottom template 3 is arranged on the base 1, the pressing template 4 is arranged on the lifting head 2, the bottom template 3 is provided with a first supporting groove 301 and a second supporting groove 302, so the first supporting groove 301 and the second supporting groove 302 are not on the same plane, the pressing template 4 is provided with a first extrusion protrusion 401 and a second extrusion protrusion 402, and the first extrusion protrusion 401 and the second extrusion protrusion 402 are not on a straight line.

[0046] The working process of the angle steel bending device is as follows: first, the angle steel to be bent is placed on the bottom template 3, and then the lifting head 2 drives the pressing template 4 to move toward the bottom template 3, and the angle steel is bent under the extrusion of the bottom template 3 and the pressing template 4, thereby completing the bending process of the angle steel. After the angle steel is bent, the first supporting groove 301, the second supporting groove 302, the first extrusion protrusion 401 and the second extrusion protrusion 402 are close to the angle steel.

[0047] Specifically in the present bending device, the lifting head 2 can be a hydraulic lifting head 2 or an electric lifting head 2.

[0048] In summary, in this angle steel bending device, only the lifting head 2 is installed on the press plate 4. When the lifting head 2 is running, the press plate 4 moves closer to or away from the bottom plate 3. Only one lifting head 2 is operated during the entire bending process to complete the extrusion bending process. The entire extrusion bending process is reliable, and the error between the angle steel parts after extrusion bending is relatively smaller.

[0049] As attached Figure 1 ~Attached Fig. 9 As shown, it also includes an electric heating sleeve 5, which is arranged on one side of the base 1.

[0050] Specifically, the electric heating sleeve 5 uses industrial frequency alternating current. After the electric heating sleeve 5 heats the angle steel, the angle steel is placed on the bottom template 3, and then the angle steel is squeezed and bent by the bottom template 3 and the pressure template 4, and finally the entire bending process is completed.

[0051] Specifically, the electric heating sleeve 5 of this type is a right-angled electric heating sleeve 5 , and the angle steel can pass between the electric heating sleeves 5 before being bent.

[0052] As attached Figure 1 ~Attached Fig. 9 As shown, it also includes a conveying frame 6 and a pushing frame 7. The conveying frame 6 is arranged on one side of the electric heating sleeve 5. A guide rail 8 is arranged on one side of the conveying frame 6. A rack 9 is arranged on one side of the guide rail 8. The rack 9 and the guide rail 8 are in a parallel state. The pushing frame 7 and the guide rail 8 are slidably matched together. The pushing frame 7 is provided with a pushing motor 10. The shaft of the pushing motor 10 is matched with the rack 9 through a gear.

[0053] The specific function of the conveying frame 6 is to guide and clamp the angle steel. When the angle steel is subjected to external force, the angle steel can move on the conveying frame 6. When the angle steel is pushed by external force, it can enter the electric heating sleeve 5 for heating. After the heating is completed, it can also be moved out of the conveying frame 6 through the conveying frame 6 under the action of external force. At the same time, in this bending device, a guide rail 8 is set on one side of the conveying frame 6, and a rack 9 parallel to the guide rail 8 is set on one side of the guide rail 8. The pushing frame 7 is slidably installed on the guide rail 8. The pushing motor 10 is set on the pushing frame 7. The shaft of the pushing motor 10 is meshed with the rack 9 through a gear. When the pushing motor 10 is running, the pushing frame 7 slides along the guide rail 8. When the pushing frame 7 slides, it can push the angle steel on the conveying frame 6 to move on the conveying frame 6. When the angle steel slides on the sliding frame, it can slide into the electric heating sleeve 5 or slide out of the electric heating sleeve 5.

[0054] The specific conveying frame includes a base plate 601 and a plurality of supporting rollers 602. The base plate 601 is an isosceles trapezoidal base plate 601. Supporting rollers 602 are rotatably installed at both ends of the base plate 601. The supporting rollers 602 are in a rotatable state relative to the base plate 601. The supporting rollers 602 are used to contact the outer wall surface of the angle steel. The rotation of the supporting rollers 602 can allow the angle steel to slide relative to the base plate 601.

[0055] Specifically in this device, in order to be able to stably push the angle steel to move on the conveying frame 6, two tensioning hooks 11 and a clamping cylinder 12 are further arranged on the pushing frame. The two tensioning hooks 11 are rotatably installed on the pushing frame, and the other ends of the two tensioning hooks 11 are matched with the clamping cylinder 12. When the cylinder rod of the clamping cylinder 12 contracts, the two tensioning hooks 11 move closer to each other. When the two tensioning hooks 11 move closer, they can clamp the angle steel. When the cylinder rod of the clamping cylinder 12 extends, the two tensioning hooks 11 stretch out, and the two tensioning hooks 11 no longer clamp the angle steel.

[0056] When the two tensioning hooks 11 clamp the angle steel, the pushing frame can move back and forth stably on the conveying frame 6 with the angle steel.

[0057] Specifically, this device also includes a plurality of lifting cylinders 13. The lifting cylinders 13 are fixedly installed on a frame 14. The frame 14 is arranged on one side of the base 1. The guide rails 8 and the racks 9 are also installed on the frame 14. There are multiple conveying racks 6 in this device. Some of the conveying racks 6 are fixedly installed on the frame 14, and the other conveying racks 6 are installed on the cylinder rods of the lifting cylinders 13 through their own bottom plates. When the cylinder rods of the lifting cylinders 13 are extended or retracted, the conveying racks 6 are raised or lowered relative to the frame 14. When the cylinder rods of the lifting cylinders 13 are extended or retracted, the conveying racks 6 are raised or lowered relative to the frame 14. When the cylinder rods of the lifting cylinders 13 are extended, all the conveying racks 6 are arranged together to form a complete conveyor belt, which can continuously and stably transport angle steels. When the cylinder rods of the lifting cylinders 13 are retracted, all the conveying racks 6 no longer form a complete conveyor belt, and an avoidance gap is formed on the conveyor belt (see the attached figure). Fig. 9 As shown in the figure, both ends of the conveying frame 6 are in a suspended state), the existence of the avoidance gap makes it easier for the clamping claws on the robot arm 15 to clamp the angle steel, ensuring that the clamping claws have good clamping efficiency for the angle steel.

[0058] As attached Figure 1 ~Attached Fig. 9 As shown, it also includes a mechanical arm 15 and a clamping claw, the clamping claw is arranged on the mechanical arm 15, and the mechanical arm 15 is arranged on one side of the base 1.

[0059] Specifically, the clamping claw is installed on the mechanical arm 15, and the clamping claw is used to clamp the angle steel, while the function of the mechanical arm 15 is to transport the angle steel after clamping the angle steel.

[0060] The specific clamping claws include a clamping seat 1601, an electromagnetic adsorption claw 1602 and a suspension clamp 1603. The electromagnetic adsorption claw 1602 is installed on the clamping seat 1601. The electromagnetic adsorption claw 1602 directly uses magnetic attraction to adsorb and clamp the angle steel. Before the angle steel is heated by the electric heating sleeve 5, the angle steel can be clamped by the electromagnetic adsorption claw 1602. Specifically, a slide rail 1604 is also installed in the clamp seat 1601, and there are two suspension clamps 1603. The two suspension clamps 1603 are slidably installed on the slide rails 1604 respectively. An adjusting screw 1605 is rotatably installed in the clamp seat 1601. The adjusting screw 1605 and the slide rail 1604 are in a parallel and non-contact state. The two ends of the adjusting screw 1605 are respectively matched with the two suspension clamps 1603 by threaded matching. The clamp seat 1601 is installed with an adjusting motor 1606. The shaft of the adjusting motor 1606 is matched with the adjusting screw 1605 through a coupling 1607. The two suspension clamps 1603 are located on both sides of the coupling 1607. When the adjusting motor 1606 rotates, the two suspension clamps 1603 move closer to each other or move away from each other, thereby realizing the adjustable distance installation of the suspension clamp 1603, ensuring that the suspension clamp 1603 can stably clamp the hanging angle steel.

[0061] The specific clamping seat 1601 is used for installation and coordination with the robot arm.

[0062] As attached Figure 1 ~Attached Fig. 9 As shown, the lifting garage 17 is also included, and the lifting garage 17 is arranged on one side of the base platform 1.

[0063] The lifting warehouse 17 serves as a warehouse, and can be used to store angle steels before bending and angle steels after bending.

[0064] As attached Figure 1 ~Attached Fig. 9 As shown, it also includes a temporary storage table 18, which is arranged on one side of the base 1. A rotating seat 19 is arranged on one side of the temporary storage table 18.

[0065] The specific temporary storage table 18 is also located on one side of the conveying frame 6. The functions of the rotating seat 19, the supporting arm 20 and the electromagnetic magnet are to adsorb and reverse the angle steel, and the function of the temporary storage table 18 is to place the reversed angle steel. The specific whole process is as follows. First, the angle steel on the conveying frame 6 is in a state of opening upward. At this time, the rotating shaft 1901 rotates, so that the electromagnetic magnet on the supporting arm 20 attracts the angle steel, and then the rotating shaft 1901 rotates in the opposite direction. The reverse rotation of the rotating shaft 1901 drives the supporting arm 20 to rotate in the opposite direction. After the supporting arm 20 rotates in the opposite direction, the angle steel will reach the temporary storage table 18. When the angle steel contacts the temporary storage table 18, the electromagnetic magnet no longer attracts the angle steel. After the electromagnetic magnet releases the angle steel, the rotating shaft 1901 drives the supporting arm 20 to rotate again.

[0066] As attached Figure 1 ~Attached Fig. 9 As shown, it also includes a supporting platform 21, which is arranged on the periphery of the base.

[0067] The supporting platform 21 is used to temporarily place the unbent angle steel 2301 and the bent angle steel 2302 .
