[0003] Most existing steel bending devices use punches and dies to bend and plastically shape various types of steel.

However, ... Figure 9 As shown, since the internal corner guard 200 requires the side of the half I-beam 100 to be bent in an inward concave manner, simply bending the half I-beam 100 with the punch and die can easily cause the upper and lower sides of the half I-beam 100 to be bent and deformed.

[0014] As a further aspect of the present invention: the heating assembly includes a heating base, heating grooves are symmetrically arranged on both sides of the top of the heating base, and heating plates are arranged in the heating grooves.

[0015] As a further embodiment of the present invention: the side flattening component includes a flattening frame in the middle of the top surface of the bending machine, an extrusion chamber is provided in the middle of the flattening frame, and flattening cylinders are symmetrically arranged on the upper and lower sides of the flattening frame. The telescopic rod of the flattening cylinder passes through the flattening frame and is connected to the flattening plate.

[0016] As a further aspect of the present invention: a bending method for edge-protecting steel for internal corner glass, using the above-mentioned bending device, includes the following steps:

[0017] Step 1: The semi-I-beams conveyed on the production line are held in place by a robotic arm and placed into the heating base. The heating plate is then energized to heat the semi-I-beams.

[0018] Step 2: After heating is complete, the robotic arm removes the heated half-I-beam and simultaneously starts the rotary motor, which drives the turntable to rotate. The turntable drives the clamping base to rotate 180 degrees. The robotic arm clamps the heated half-I-beam onto the clamping base. The rotary motor is started again to reset the clamping base.

[0019] Step 3: Start the hydraulic cylinder to push the pressure base to move. The pressure base and the clamping base cooperate to extrude and bend the heated half-I-beam. Then, the pressure is held. After the pressure holding is completed, the hydraulic cylinder drives the pressure base to retract and move out of the extrusion chamber.

[0020] Step 4: Activate the leveling cylinders on both sides to move the leveling plate inward and apply pressure to level the upper and lower sides of the bent half-I-beam.

[0021] Step 5: After the extrusion is completed, start the material release telescopic rod to move the pusher arc plate and push the bent half-I-beam that is stuck on the clamping base to release the material. At the same time, the moving connecting shaft moves the sliding plate, the sliding plate moves the connecting rod, and the connecting rod moves the piston forward to extrude the material. Gas is blown outward to accelerate the release of the bent half-I-beam from the clamping base. After release, it is grabbed by the robot arm for the next step of cooling to obtain the internal corner guard.

[0022] The beneficial effects of this invention are:

[0023] 1. The present invention provides a heating component on the connecting substrate to heat the semi-I-beam, thereby preventing the cold steel from bending and breaking, and further increasing the toughness and plasticity of the semi-I-beam, which facilitates subsequent bending and forming. In conjunction with the side flattening component, the upper and lower flattening plates apply pressure to the semi-I-beam while it is at high temperature, flattening the slight deformation and bending caused by the concave bending of the upper and lower sides.

[0024] 2. The rotating clamping and bending assembly of this invention is rotatable, enabling the transfer of the semi-I-beam from the heating assembly to the bending and forming area. The rotating clamping and bending assembly combines heating and bending, allowing bending to occur during the heating process, saving overall processing time and improving processing efficiency. Furthermore, the rotating motor drives the turntable to rotate, and the turntable drives the clamping base to switch between the left and right workstations. In conjunction with the robotic arm, continuous processing is achieved.

[0025] 3. This invention activates the material release telescopic rod, which drives the pusher arc plate to move, pushing the bent half-I-beam clamped on the clamping base to release the material. At the same time, the moving connecting shaft drives the sliding plate to move, the sliding plate drives the connecting rod to move, and the connecting rod drives the piston to squeeze forward, blowing gas outward, which accelerates the release of the bent half-I-beam from the clamping base. The first and second air grooves enable the piston to move smoothly, so that while the pusher arc plate pushes the material, the gas in the high-pressure sealing groove is squeezed out and released, which accelerates the material release.

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Since the internal corner guard 200 requires the side of the half I-beam 100 to be bent in an inward concave manner, it is easy to cause the upper and lower sides of the half I-beam 100 to be bent by only the punch and die.

[0039] In view of this, such as Figures 1-7 As shown, a bending device for the edge protection steel of the inside corner glass is designed to produce the inside corner protection steel 200. The device processes the half I-beam 100 by adding a side flattening component 3 to form the inside corner protection steel 200, and avoids side protrusion and bending deformation.

[0040] like Figure 1As shown, the bending device includes a bending machine 1 fixed on the production line. A movable pressure bending component 2 is provided on one side of the top of the bending machine 1, and a rotary clamping bending component 4 is provided on the other side, with the two positions corresponding to each other. Furthermore, a side flattening component 3 is provided in the working area where the movable pressure bending component 2 and the rotary clamping bending component 4 work together. The side flattening component 3 is fixed in the middle of the top of the bending machine 1. A connecting base plate 5 is connected to the outside of the bending machine 1 near the rotary clamping bending component 4. A heating component 6 is provided on the connecting base plate 5. The heating component 6 heats the semi-I-beam 100 to prevent the cold steel from breaking during bending, further increasing the toughness and plasticity of the semi-I-beam 100, facilitating subsequent bending and forming, and cooperating with the side flattening component 3 to prevent side protrusion bending.

[0041] Furthermore, the rotary clamping bending component 4 is rotatable, enabling the transfer of the semi-I-beam 100 from the heating component 6 to the bending forming area. A robotic arm (not shown in the figure) is installed between the rotary clamping bending component 4 and the heating component 6 to clamp the semi-I-beam 100. The rotary clamping bending component 4 combines heating and bending, allowing bending to be performed during the heating process, saving overall processing time and improving processing efficiency.

[0042] Further, such as Figure 2 and Figure 3 As shown, the aforementioned movable pressure bending assembly 2 includes a fixed base 21 fixed on the table surface of the bending machine 1, and the fixed base 21 is reinforced with ribs on its outer side. Guide posts 24 are symmetrically arranged at the four corners of the inner side of the fixed base 21, and a pad 23 is fitted on the guide post 24. The pad 23 is fixedly connected to the fixed base 21. A movable base plate 25 is also fitted on the guide post 24. The movable base plate 25 is connected to a pressure base 26 on the side near the rotary clamping bending assembly 4. A hydraulic cylinder 22 is fixedly connected to the center of the outer side of the fixed base 21. The telescopic rod of the hydraulic cylinder 22 passes through the fixed base 21 and the pad 23 and is connected to the movable base plate 25. The extension and retraction of the pressure base 26 is realized by the hydraulic cylinder 22, which cooperates with the rotary clamping bending assembly 4 to perform bending processing.

[0043] Further, such as Figure 1 , Figure 2 and Figure 3As shown, the aforementioned rotary clamping bending assembly 4 includes a turntable 45 rotatably mounted on the bending machine 1. A fixed base 41 is fixedly connected to the top of the turntable 45. A pad 42 is connected to the side of the fixed base 41 near the movable pressure bending assembly 2. A clamping base 43 is connected to the pad 42. The outer side of the clamping base 43 is a convex arc surface, which cooperates with the outer side of the pressure base 26, which is a concave arc surface. The two arc surfaces cooperate to achieve the bending processing of the half I-beam 100. Furthermore, the bending machine 1 has an installation cavity 11 inside. A rotary motor 46 is installed in the installation cavity 11. The output shaft of the rotary motor 46 passes through the top plate of the bending machine 1 and is connected to the turntable 45, so that the rotary motor 46 drives the turntable 45 to rotate. The turntable 45 drives the clamping base 43 to switch between the left and right work positions. With the help of the robot, the processing continuity is achieved.

[0044] To facilitate unloading after processing, a feature is provided inside the clamping base 43. Figure 4 The stripping assembly 47 shown has a stripping telescopic rod 44 installed inside the fixed base 41. The front end of the stripping telescopic rod 44 is connected to the stripping assembly 47 to realize the telescopic pushing action. When the half-I-beam 100 is stuck in the clamping base 43, and then squeezed and bent by the pressure base 26, it will be stuck on the clamping base 43 and difficult to strip. By the telescopic pushing of the stripping assembly 47, the formed internal corner guard 200 is pushed out of the clamping base 43 and is clamped by the production line robot for subsequent processing.

[0045] Further, such as Figure 7 As shown, in order to heat the semi-I-beam 100 and enhance its plasticity, a heating assembly 6 is provided. The heating assembly 6 includes a heating base 61 fixed on the connecting base plate 5. Heating grooves are symmetrically arranged on both sides of the top of the heating base 61, and heating plates 62 are symmetrically arranged on both sides of the heating grooves. A heating plate 62 is also provided on the top surface in the middle to heat the inner cavity surface of the semi-I-beam 100. By heating the semi-I-beam 100 with multiple heating plates 62, the plasticity and toughness of the steel are increased, which facilitates subsequent bending operations.

[0046] Furthermore, to ensure the flatness of the side after bending, a heating component 6 is first installed for heating, and then... Figure 6As shown, a side flattening component 3 is provided. The side flattening component 3 includes a flattening frame 31 in the middle of the top surface of the bending machine 1. The flattening frame 31 is welded to the bending machine 1. An extrusion chamber 32 is opened in the middle of the flattening frame 31. The length of the extrusion chamber 32 is greater than the distance from the center of the turntable 45 to the top surface of the clamping base 43, so that the clamping base 43 can rotate in with the half I-beam 100. Furthermore, flattening cylinders 34 are symmetrically arranged on the upper and lower sides of the flattening frame 31. The telescopic rod of the flattening cylinder 34 passes through the flattening frame 31 and is connected to the flattening plate 35. Moving grooves 33 are opened in the middle of the upper and lower sides of the extrusion chamber 32. The upper and lower flattening plates 35 slide in the moving grooves 33 in the corresponding positions. The upper and lower flattening plates 35 pressurize the half I-beam 100 when it is at high temperature, flattening the small deformations and bends caused by the concave bending of the upper and lower sides.

[0047] After the bent half-I-beam 100 (i.e., the internal corner guard 200) is flattened under pressure, the upper and lower sides of the internal corner guard 200 are tightly engaged with the clamping base 43. It cannot be removed simply by pulling it out from the opposite side using a robotic arm. Therefore, if... Figure 4 and Figure 5 As shown, a material release assembly 47 is provided in the clamping base 43 for effective material release. The material release assembly 47 includes a connecting shaft 471 connected to the material release telescopic rod 44. The connecting shaft 471 passes through the clamping base 43 and is connected to a pushing arc plate 475. The pushing arc plate 475 is disposed in a mating groove 434 opened on the arc surface of the clamping base 43. The clamping base 43 further includes a base body 431. A first motion groove 432 is opened at the tail of the base body 431 and is symmetrical inside the base body 431. Multiple high-pressure sealing grooves 433 are provided. A mating groove 434 is provided on the arc surface of the base body 431 for mating with the pusher arc plate 475. Sliding plates 472 are symmetrically connected to both ends of the connecting shaft 471. These sliding plates 472 are slidably disposed in the first motion groove 432. Multiple connecting rods 473 are symmetrically arranged on the inner surfaces of the two sliding plates 472. The other ends of each connecting rod 473 pass through the corresponding high-pressure sealing groove 433 and are connected to a piston 474. To achieve the movement of the piston 474, as follows... Figure 5 As shown, a first air groove 435 is symmetrically provided at both the upper and lower ends of the high-pressure sealing groove 433 near the arc surface of the clamping base 43, and the outer end of the first air groove 435 is located in the inner cavity of the half-I-beam 100. A second air groove 436 is provided at the top of the high-pressure sealing groove 433 near the sliding plate 472. The piston 474 moves smoothly through the first air groove 435 and the second air groove 436, so that while the pushing arc plate 475 pushes the material, the gas in the high-pressure sealing groove 433 is squeezed out and released, which speeds up the unloading.

[0048] A further bending method for the corner glass using edge-protecting steel, employing the aforementioned bending device, includes the following steps:

[0049] Step 1: The semi-I-beam 100 conveyed on the production line is held by a robotic arm and placed into the heating base 61. The heating plate 62 is energized to heat the semi-I-beam 100.

[0050] Step 2: After heating is completed, the robotic arm takes out the heated half-I-beam 100 and starts the rotary motor 46 simultaneously, which drives the turntable 45 to rotate. The turntable 45 drives the clamping base 43 to rotate 180 degrees. The robotic arm clamps the heated half-I-beam 100 onto the clamping base 43. The rotary motor 46 is started again to drive the clamping base 43 to reset.

[0051] Step 3: Start the hydraulic cylinder 22 to push the pressure base 26 to move. The pressure base 26 cooperates with the clamping base 43 to extrude and bend the heated half-I-beam 100. Then, pressure is maintained. After the pressure is maintained, the hydraulic cylinder 22 drives the pressure base 26 to retract and move out of the extrusion chamber 32.

[0052] Step 4: Activate the leveling cylinders 34 on both sides to move the leveling plate 35 inward and apply pressure to level the upper and lower sides of the bent half-I-beam 100.

[0053] Step 5: After the extrusion is completed, the material release telescopic rod 44 is activated, which drives the pusher arc plate 475 to move and push the bent half-I-beam 100, which is clamped on the clamping base 43, to release the material. At the same time, the moving connecting shaft 471 drives the sliding plate 472 to move. The sliding plate 472 drives the connecting rod 473 to move. The connecting rod 473 drives the piston 474 to press forward and blow out the gas, which accelerates the release of the bent half-I-beam 100 from the clamping base 43. After release, it is grabbed by the robot arm for the next step of cooling to obtain the internal corner guard 200.

[0054] In this invention, the pressure holding time in step three is set manually, and the number of pressure leveling cycles in step four is also set manually.

[0055] In step five of this invention, during the early stage of piston 474 movement, the first air groove 435 is blocked by the side of the bent half-I-beam 100, and the air pressure increases during the movement until it is blown out from the outer port of the first air groove 435, so that there is gas between the side of the bent half-I-beam 100 and the clamping base 43, which facilitates material removal.

[0056] In the description of this invention, it should be understood that the terms "upper," "lower," "left," and "right," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on the invention.

[0057] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," etc., should be interpreted broadly.

All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.

Step 5: After the extrusion is completed, start the material release telescopic rod (44) to move the pusher arc plate (475) to push the bent half-I-beam (100) that is clamped on the clamping base (43) to release the material. At the same time, the moving connecting shaft (471) moves the sliding plate (472), the sliding plate (472) moves the connecting rod (473), the connecting rod (473) moves the piston (474) forward to squeeze, and the gas blows out to accelerate the bending half-I-beam (100) to get off the clamping base (43). After getting off, it is grabbed by the robot arm for the next step of cooling to obtain the internal corner guard (200).
