[0002] Steel structures are structures made primarily of steel and are one of the main types of building structures. Steel structures are mainly composed of steel beams, steel columns, steel trusses and other components made of steel profiles and steel plates. These components or parts are usually connected by welds, bolts or rivets. After the steel structure components are manufactured in the factory, they are assembled on the construction site to achieve the overall construction of the building structure.

During the manual ejection process, operators may face safety risks such as mechanical injury and being struck by objects. This utility model proposes a bending device for steel structure production.

[0008] Preferably, the transmission mechanism includes a motor, one side of which is fixedly mounted on one side of the base plate, and a rotating wheel is fixedly connected to the output end of the motor.

[0014] The advantages of this utility model are:

[0015] This invention utilizes the U-shaped frame and connecting plate in the ejector assembly for primary support and connection. During the bending process, the steel structure pushes the ejector rod downwards along the U-shaped frame and stretches the first spring. The position of the ejector rod is reinforced by the limiting plate, improving the stability of the ejector rod displacement. When the ejector rod descends to a certain position, the resistance pad engages with the slot, creating friction between the ejector rod and the U-shaped frame. After the steel structure is bent, the extrusion assembly first resets. Due to the engagement of the resistance pad and the slot, the first spring rebounds slowly, pulling the ejector rod back to its original position. When the resistance pad disengages from the slot, the ejector rod quickly pops out and resets, ejecting the bent steel structure. Thus, this device has a simple and compact structure, effectively achieving automatic ejection of the steel structure. It solves the problem that most traditional bending devices used in steel structure production are not convenient for automatically ejecting the formed steel. When the bent part cannot be automatically ejected, manual removal is required, which increases operating time and reduces overall production efficiency. During manual ejection, operators may face safety risks such as mechanical injury and being struck by objects. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0026] This application discloses a bending device for steel structure production. (Refer to...) Figures 1 to 3 A bending device for steel structure production includes a base plate 1, a transmission mechanism 2 is provided on one side of the base plate 1, an extrusion assembly 3 is provided on one side of the transmission mechanism 2, a forming assembly 4 is provided on one side of the extrusion assembly 3, and an ejection assembly 5 is provided on one side of the forming assembly 4.

[0027] The ejector assembly 5 includes a U-shaped frame 501. A connecting plate 502 is fixedly connected to one side of the U-shaped frame 501, and one side of the connecting plate 502 is fixedly connected to one side of the base plate 1. A push rod 503 is slidably connected to the inner cavity of the U-shaped frame 501. A limiting plate 504 is fixedly connected to the surface of the push rod 503, and the surface of the limiting plate 504 is slidably connected to the inner cavity of the U-shaped frame 501. A slot 505 is provided on one side of the U-shaped frame 501, and a resistance-increasing pad 506 is fixedly connected to the surface of the limiting plate 504. The surface of 506 is fitted to the inner wall of the slot 505. One end of the push rod 503 is fixedly connected to the positioning plate 507. A first spring 508 is sleeved on the surface of the push rod 503. One end of the first spring 508 is fixedly connected to one side of the U-shaped frame 501 and the other end of the positioning plate 507. The base plate 1 of the bending device for steel structure production plays a major supporting and mounting role. The transmission mechanism 2 on one side of the base plate 1 can be regarded as the main power source. The steel structure is placed on one side of the forming component 4. The transmission mechanism 2 pushes the extrusion component 3 to extrude and bend the steel structure. The U-shaped frame 501 and the connecting plate 502 in the ejector component 5 play a major supporting and connecting role. During the bending process, the steel structure pushes the push rod 503 down along the U-shaped frame 501 and stretches the first spring 508. The position of the push rod 503 is reinforced by the limiting plate 504 to improve the stability of the displacement of the push rod 503. When the push rod 503 descends to a certain position, the resistance pad... The fit between the 506 pad and the slot 505 creates a certain friction between the push rod 503 and the U-shaped frame 501. After the steel structure is bent and formed, the extrusion assembly 3 first resets. Due to the fit between the friction pad 506 and the slot 505, the first spring 508 rebounds and slowly pulls the push rod 503 back to its original position. When the friction pad 506 and the slot 505 are no longer in contact, the push rod 503 quickly pops out and resets, pushing out the bent steel structure. Thus, the device has a simple and compact structure and can effectively achieve the effect of automatic ejection of the steel structure.

[0028] Reference Figure 3 One end of the push rod 503 is fixedly connected to a contact element 6, and a protective pad 7 is fixedly connected to one side of the contact element 6. The contact element 6 is larger than the diameter of the push rod 503, which increases the contact area between the contact element 6 and the steel structure, ensuring that the steel structure is not damaged when it is pushed out. The protective pad 7 made of rubber can further improve the protection of the steel structure when it is pushed out.

[0029] Reference Figure 1 , Figure 4 and Figure 5The transmission mechanism 2 includes a motor 201. One side of the motor 201 is fixedly mounted on one side of the base plate 1. The output end of the motor 201 is fixedly connected to a rotating wheel 202. One side of the rotating wheel 202 is attached to one side of the base plate 1. A protruding plate 203 is fixedly connected to the surface of the rotating wheel 202. The motor 201 can drive the rotating wheel 202 to rotate through the rotating wheel 202. The protruding plate 203 is fixedly connected to the rotating wheel 202 by bolts, which makes it easy to replace the protruding plate 203 of different sizes, change the stroke of the extrusion assembly 3, and adapt to the angle of different steel structures for bending.

[0030] Reference Figure 5 A threaded cylinder 8 is fixedly connected to the surface of the rotating wheel 202. A one-way screw 9 is threadedly connected to the inner cavity of the threaded cylinder 8. A support member 10 is fixedly connected to one end of the one-way screw 9. The surface of the support member 10 is in contact with the inner wall of the convex plate 203. Through the support member 10, the threaded cylinder 8 plays the main supporting role. The one-way screw 9 can change the length of the support member 10 so as to support convex plates 203 of different sizes and improve the strength of the convex plate 203.

[0031] Reference Figure 1 The extrusion assembly 3 includes a limiting member 301, one side of which is fixedly connected to one side of the base plate 1. A push block 302 is slidably connected to the inner wall of the limiting member 301. One end of the push block 302 contacts the surface of the protrusion plate 203. A push rod 303 is fixedly connected to one end of the push block 302. An extrusion member 304 is fixedly connected to one end of the push rod 303. A stabilizing plate 11 is fixedly connected to one side of the base plate 1. The surface of the push rod 303 is slidably connected to the inner cavity of the stabilizing plate 11. A second spring 12 is sleeved on the surface of the push rod 303. One end of the second spring 12 is fixedly connected to one end of the push block 302. One end of the spring 12 is fixedly connected to one side of the stabilizing plate 11. Through the provided extrusion assembly 3, the rotating wheel 202 can drive the protruding plate 203 to rotate synchronously. The protruding part of the protruding plate 203 can contact the push block 302 and push the push block 302, the push rod 303 and the extrusion component 304. The extrusion component 304 can bend and form the steel structure by descending. The stability of the push rod 303 is improved by the stabilizing plate 11. The second spring 12 is set between the push block 302 and the stabilizing plate 11. The displacement of the push block 302 can squeeze the second spring 12. The second spring 12 releases elastic potential energy to reset the push rod 303.

[0032] Reference Figure 4 and Figure 6The molding component 4 includes two molding plates 401. T-shaped blocks 402 are fixed to one side of each molding plate 401. The surfaces of the T-shaped blocks 402 are slidably connected to the inner cavity of the base plate 1. A threaded plate 13 is fixedly connected to one side of the molding plate 401. The surface of the threaded plate 13 is slidably connected to the inner cavity of the base plate 1. A bracket 14 is fixedly connected to one side of the base plate 1. A bidirectional screw 15 is rotatably connected to the inner cavity of the bracket 14. The inner wall of the threaded plate 13 is threadedly connected to the surface of the bidirectional screw 15. Through the molding component 4, the molding plate 401 can be regarded as a bending forming mold for steel structure. The molding plate 401 is connected to the base plate 1 through the T-shaped blocks 402. The bidirectional screw 15 is connected to the base plate 1 through the bracket 14. The molding plate 401 is threadedly connected to the bidirectional screw 15 through the threaded plate 13. The rotation of the bidirectional screw 15 can adjust the spacing of the molding plates 401.

[0033] Working principle: The base plate 1 serves as the main support and mounting element. The transmission mechanism 2 on one side of the base plate 1 can be considered the main power source. The steel structure is placed on one side of the forming assembly 4. The transmission mechanism 2 pushes the extrusion assembly 3 to extrude and bend the steel structure. The U-shaped frame 501 and connecting plate 502 in the ejector assembly 5 serve as the main support and connection elements. During the bending process, the steel structure pushes the ejector rod 503 down along the U-shaped frame 501 and stretches the first spring 508. The position of the ejector rod 503 is reinforced by the limiting plate 504, raising the position of the ejector rod 503. Regarding displacement stability, when the top rod 503 descends to a certain position, the resistance pad 506 and the slot 505 come into contact, creating a certain friction between the top rod 503 and the U-shaped frame 501. After the steel structure is bent and formed, the extrusion assembly 3 first resets. Due to the contact between the resistance pad 506 and the slot 505, the first spring 508 rebounds and slowly pulls the top rod 503 back to its original position. When the resistance pad 506 and the slot 505 are no longer in contact, the top rod 503 quickly pops out and resets, pushing out the bent steel structure. Thus, the device has a simple and compact structure and can effectively achieve the effect of automatic ejection of the steel structure.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
