[0023] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0024] Example 1 Please refer to Figure 1-Figure 8 As shown, a steel structure processing bending machine and a bending method thereof, include a workbench 1, a buffer mechanism 2 is arranged inside the workbench 1, and the characteristics are as follows: a mounting plate 3 is installed on the top of the buffer mechanism 2, a material ejecting mechanism 4 is arranged in the middle of the upper end of the mounting plate 3, a bending die 5 is arranged on the top of the material ejecting mechanism 4, a fixing mechanism 6 is arranged on the front and rear sides of the upper end of the mounting plate 3, vertical poles 7 are symmetrically fixedly installed on the four corners of the upper end of the workbench 1, a movable plate 8 is slidably installed on the surface of the vertical pole 7, a disassembly mechanism 9 is arranged at the lower end of the movable plate 8, a top plate 10 is fixedly installed on the top of the vertical pole 7, hydraulic cylinders 11 are symmetrically fixedly installed on both sides of the top plate 10, and through openings 51 are symmetrically penetrated on both sides of the bending groove.

[0025] The four corners of the lower end of the mounting plate 3 are fixedly connected to the top of the support 28 , and the lower end of the output rod of the hydraulic cylinder 11 is fixedly mounted to the upper end of the moving plate 8 .

[0026] S1. The steel structure plate can be placed through the bending die 5, and then the rotating bidirectional screw 62 can drive the movable seat 64 connected by threads on both sides to gradually approach, so that its limit clamping plate 67 moves synchronously, so that the two sides of the steel structure plate on the bending die 5 can be limited and clamped, so that it is not easy to deviate during bending, thereby improving the bending quality; S2, the output rod of the hydraulic cylinder 11 can push the movable plate 8 to move downward, so that the bending cutter head 94 at the lower end of the movable plate 8 can be used to bend the steel structure plate on the bending die 5, and after the bending is completed, the movable plate 8 and the bending cutter head 94 are reset upward; S3, the screw rods 43 on both sides are driven to rotate by the double-axis motor 42, so that the threaded seats on the screw rods 43 are gradually brought closer, so that the ejector column 48 can be pushed upwards by the hinged action of the hinged seat 1 45, the connecting plate 46 and the hinged seat 2 47, so that the bent steel structure can be quickly ejected from the bending die 5, which is convenient for the operator to remove, and at the same time, the threaded seats 44 on both sides are gradually moved away, so that the ejector column 48 can be reset; S4. When the bending die 5 is used to bend the steel structure, it will move downward under the bending impact force of the bending cutter head 94, thereby driving the support 28 to move downward synchronously through the mounting plate 3, so that the fixing plate 23 will squeeze the spring 1 24 and the spring 2 26. Through the elastic effect of the spring 1 24 and the spring 2 26, the bending machine can effectively buffer the bending die 5 during long-term use to prevent the die from being damaged due to excessive bending impact force, thereby extending its service life and meeting the user's use needs. S5. By removing the bending cutter head 94 from the movable plate 8, the bending cutter head 94 that is worn and deformed due to long-term use can be replaced, which greatly reduces the downtime of the equipment, improves the maintenance efficiency of the equipment, and ensures the continuity of production.

[0027] In this solution, the use height of the movable plate 8 and the bending tool head 94 can be adjusted by the hydraulic cylinder 11, so as to facilitate the bending process of the steel structure plate. The movable plate 8 can slide on the vertical rod 7 to improve the stability of the movement of the movable plate 8.

[0028] Example 2 Please refer to Figure 5 As shown, the buffer mechanism 2 includes a slide bar 21, both ends of which are symmetrically fixedly connected to the inner sides of the workbench 1, an ear seat 22 is slidably installed on the outside of the slide bar 21, a fixing plate 23 is fixedly installed between the ear seats 22, the upper and lower outer parts of the slide bar 21 are sleeved with a spring 1 24, the bottom of the inner cavity of the workbench 1 is symmetrically fixedly connected with a telescopic rod 25, the outer part of the telescopic rod 25 is sleeved with a spring 26, the upper end surface of the workbench 1 is symmetrically penetrated with a through hole 27, and the upper four corners of the fixing plate 23 are symmetrically fixedly installed with pillars 28.

[0029] One end of spring 1 24 is fixedly connected to the upper and lower inner walls of the workbench 1, and the other end is fixedly connected to the two sides of the ear seat 22. Both ends of spring 26 are fixedly connected to the lower side of the fixed plate 23 and the opposite surface of the bottom of the inner cavity of the workbench 1. The support 28 extends out of the interior of the workbench 1 through the through-port 27.

[0030] In this scheme, the elastic effect of spring 1 24 and spring 2 26 is particularly important. When the bending machine is used frequently for a long time, the impact force generated by each bending operation will be transmitted to the spring in this way. The spring uses its own elastic deformation to convert the impact force into elastic potential energy, thereby effectively absorbing and buffering these impact forces. This buffering effect can greatly reduce the intensity of the bending impact force directly acting on the bending die 5, and prevent the die from being damaged by cracks, deformation, etc. due to excessive impact force.

[0031] In this solution, through the collaborative work of various components in the buffer structure and the effective buffering of the first spring 24 and the second spring 26, the bending die 5 of the bending machine can be well protected, and its service life is significantly extended. This enables the bending machine to maintain stable working performance during long-term use, reduces the need for frequent replacement and maintenance due to die damage, and lowers the equipment maintenance cost and downtime.

[0032] Embodiment 3 Please refer to Figure 6 As shown, the ejector mechanism 4 includes a bracket 41. The lower end of the bracket 41 is fixedly installed on both sides of the middle upper end of the mounting plate 3. A dual-axis motor 42 is fixedly installed in the middle of the bracket 41. The output ends of both ends of the dual-axis motor 42 are drivingly installed with lead screws 43. A threaded seat 44 is threadedly installed on the outside of the lead screw 43. The upper end of the threaded seat 44 is fixedly connected with a first hinge seat 45. A connecting plate 46 is rotatably installed inside the first hinge seat 45. The top of the connecting plate 46 is rotatably installed with a second hinge seat 47. The bottom end of the second hinge seat 47 is fixedly installed with an ejector post 48.

[0033] The bracket 41 is in a "C" shape. The top end of the lead screw 43 is rotatably installed on the opposite surfaces of the bracket 41. The ejector post 48 is fitted into and slidably installed inside the first through hole 51.

[0034] In this solution, through the gradual approach of the threaded seat 44, through the hinge action of the first hinge seat 45, the connecting plate 46 and the second hinge seat 47, a motion transmission system similar to a linkage structure is formed. When the threaded seat 44 moves closer, the first hinge seat 45 moves together with the threaded seat 44, driving the second hinge seat 47 to displace through the connecting plate 46. Due to the flexibility and transmissibility of this hinge connection method, the ejector post 48 can be pushed upward during this motion process, facilitating the ejection of the bent steel structure plate.

[0035] In this solution, when the threaded seat 44 gradually moves away, similarly through the action of the first hinge seat 45, the connecting plate 46 and the second hinge seat 47, the ejector post 48 will descend accordingly to realize the reset of the ejector post 48. Such a design enables the ejector structure to have good controllability and repeatability during the working process, can accurately complete the ejecting and resetting actions, provides strong support for the continuous operation of the bending machine, and further improves the efficiency and smoothness of the entire steel structure processing and production.

[0036] Embodiment 4 Please refer to Figure 7As shown, the fixing mechanism 6 includes a side plate 61, the lower end of the side plate 61 is symmetrically fixedly connected to the four corners of the upper end of the fixing plate 23, a bidirectional screw 62 is rotatably installed between the side plates 61, one end of the front end side plate 61 is fixedly connected to a motor 1 63, both sides of the bidirectional screw 62 are threadedly installed with a moving seat 64, the upper part of the bidirectional screw 62 is fixedly connected to a limiting rod 65, the outer part of the limiting rod 65 is slidably installed with a limiting block 66, the upper end of the limiting block 66 is fixedly connected to a limiting clamping plate 67, and the left end of the side plate 61 is conveniently rotatably installed with a sprocket 1 68 and a sprocket 2 69, and the outer parts of the sprocket 1 68 and the sprocket 2 69 are connected with meshing chains 610.

[0037] The output end of motor 1 63 is rotatably mounted on the top of the front bidirectional screw 62, the upper end of the movable seat 64 is fixedly connected to the lower end of the limit block 66, the bottom ends of the two sets of bidirectional screws 62 are conveniently installed with the front end transmission of sprocket 1 68 and sprocket 2 69, and a rubber pad is glued to one side of the top of the limit clamp 67.

[0038] In this solution, when the limit block 66 is driven to move synchronously by the movable seat 64, the limit block 66 will slide on the limit rod 65, thereby limiting the movable seat 64 to prevent the movable seat 64 from rotating. The rubber pad glued to the limit clamp 67 can further improve the clamping effect of the steel structure plate.

[0039] In this solution, a fixing mechanism 6 is utilized, and through a tight clamping action, the steel structure plate is not easily disturbed by external factors and deviated during the bending process, so that when the bending tool head 94 applies the bending force, the steel structure plate can always remain in the correct position, thereby ensuring the accuracy and quality of the bending.

[0040] Example 5 Please refer to Figure 8 As shown, the disassembly and assembly mechanism 9 includes a slot 91, which is opened at the lower end of the movable plate 8. An insert block 92 is slidably engaged inside the slot 91. A connecting plate 93 is fixedly installed at the lower end of the insert block 92. A bending cutter head 94 is fixedly connected to the middle part of the lower end of the connecting plate 93. Through holes 95 are symmetrically opened at the four corners of the connecting plate 93. Bolts 96 are movably inserted inside the through holes 95. Screw holes 97 are symmetrically opened on the surfaces of the four corners of the lower end of the movable plate 8.

[0041] The slot 91 and the insert block 92 are both in a “T” shape, the bolt 96 is threadedly connected to the screw hole 97 , and the bending cutter head 94 is engaged with the bending die 5 .

[0042] In this solution, the bending cutter head 94 can be installed by inserting the insert block 92 into the slot 91, and then the bolt 96 is inserted into the screw hole 97 and tightened to limit and fix the connecting plate 93 and the bending cutter head 94 so that they are not easily separated.

[0043] In this solution, the maintenance efficiency of the device can be quickly improved through the disassembly and assembly structure, so that maintenance personnel can quickly replace the worn and deformed bending cutter head 94. After the new bending cutter head 94 is installed, the equipment can quickly resume normal operation, ensuring the continuity of production.

[0044] The working principle and use process of this device are as follows: when in use, first, during processing, the steel structure plate can be placed on the bending die 5, and then the motor 63 can be started, and the motor 63 drives the front bidirectional screw 62 to rotate, and the front bidirectional screw 62 drives the sprocket 68 to rotate synchronously, and the sprocket 68 drives the sprocket to move synchronously through the meshing chain 610, so that the rear bidirectional screw 62 rotates synchronously, and the two sets of bidirectional screws 62 can drive the threaded seats 44 on both sides to gradually approach each other, so that the threaded seats 44 drive the limiting clamp 67 to move synchronously through the limiting block 66, so that the two ends of the steel structure plate can be controlled by the limiting clamp 67. The side is limited and clamped to avoid deviation when the steel structure plate is bent, so as to improve the bending quality; by starting the hydraulic cylinder 11, the output rod of the hydraulic cylinder 11 pushes the movable plate 8 downward, so that the movable plate 8 drives the connecting plate 93 and the bending cutter head 94 to move synchronously, so that the bending cutter head 94 contacts with the steel structure plate, and cooperates with the bending die 5 to perform a bending operation on the steel structure; after the bending is completed, the movable plate 8 drives the bending cutter head 94 to reset, and at this time, by starting the double-axis motor 42, the double-axis motor 42 drives the screw rods 43 on both sides to rotate, so that the screw rods 43 drive the threaded seats 44 on both sides to gradually approach, so that the threaded seats 44 drive the articulated seats 45 to move synchronously, By utilizing the articulated cooperation of the articulated seat 1 45, the connecting plate 46 and the articulated seat 2 47, the ejector column 48 can be pushed to move upward, so that the steel structure that has been bent in the bending die 5 can be ejected, so that it is convenient for the operator to take the steel structure plate, and at the same time, the threaded seat 44 is gradually moved away, so that the ejector column 48 can be reset; when the steel structure plate is bent by the bending die 5, it will move downward under the downward bending impact, so that the mounting plate 3 will drive the pillar 28 to move downward synchronously, so that the fixing plate 23 drives the ear seat 22 to move downward synchronously on the slide bar 21, so that the fixing plate 23 will press the spring 1 24, the telescopic rod 25 and the spring 2 6 is squeezed, and through the elastic effect of spring 1 24 and spring 2 26, the bending machine can effectively buffer the bending die 5 when used for a long time, so as to prevent the bending impact force from being too large and causing damage to the die, thereby extending its service life and meeting the use needs of users; when the bending cutter head 94 is used for a long time, it is easy to wear and deform. At this time, the bolt 96 can be loosened from the screw hole 97 and removed, so that the bending cutter head 94 can be pushed to the right, so that the insert block 92 can be separated from the slot 91, so as to facilitate the removal of the bending cutter head 94, so that it can be maintained or replaced, which greatly improves the use effect of the bending machine.
