Description

Technical Field

[0001] This application relates to the technical field of steel structure component processing equipment, and more particularly to a steel structure connector bending processing equipment. Background Technology

[0002] In modern architecture, bridges, towers and masts and other large-scale engineering projects, steel structures have become the preferred solution for core load-bearing systems due to their high strength, high stability and ease of assembly. As key components for achieving precise docking and force transmission between components, the processing quality of steel structure connectors directly determines the structural safety and service life of the overall project. These connectors are usually made of high-strength steel plates and need to be formed through multiple processes such as cutting and bending. Among them, bending is the core process that gives the connectors specific angles and complex geometric structures.

[0003] In related technologies, when bending high-strength steel or thick plate connectors, the steel plate undergoes plastic deformation under the pressure of the die. The bending area tightly wraps around the surface of the upper die (press die) and forms a tight fit with the inner wall of the lower die (die groove), resulting in a large adsorption force and friction. This adhesion phenomenon is more prominent when processing connectors with complex curved surfaces or small radius fillets. Existing solutions mostly rely on manual operation, such as knocking the die or using a pry bar to pry the workpiece to achieve demolding. This method is not only inefficient and prolongs the production cycle, but also easily causes scratches on the workpiece surface and deformation of the edges and corners, which damages the dimensional accuracy and appearance quality of the connector. Summary of the Invention

[0005] Therefore, one objective of this application is to provide a steel structure connector bending processing equipment that can quickly separate the product from the mold after bending the steel structure connector, thereby effectively protecting the workpiece surface, improving demolding efficiency and product qualification rate.

The second pressing mold is slidably connected between the two first pressing molds. The lower end of the adjusting rod is connected to the top of the first pressing mold. The upper end of the adjusting rod passes through the connecting frame and the mounting plate in sequence. A fixing ring is fixedly connected to the surface of the adjusting rod. A first spring is fixedly connected to the top of the fixing ring. The upper end of the first spring is fixedly connected to the bottom of the mounting plate. The lower end of the first spring is fixedly connected to the inner side of the connecting frame.

[0007] The steel structure connector bending processing equipment of this application embodiment can achieve rapid separation of the product and the mold after bending the steel structure connector, thereby effectively protecting the workpiece surface, improving demolding efficiency and product qualification rate.

[0008] In addition, the steel structure connector bending processing equipment proposed above in this application may also have the following additional technical features: In one embodiment of this application, the support structure includes a support block, an air injection pipe, and an electric heating pipe. The support block is fixedly connected to the top of the base plate, and a mold groove is formed on the top of the support block. A connecting cavity is formed inside the support block, and the electric heating pipe is fixedly connected to the inside of the connecting cavity. The air injection pipe is disposed on one side of the support block and communicates with the connecting cavity. The inner wall of the mold groove has evenly distributed mounting cavities, and the inner wall of the mounting cavity has connecting holes that communicate with the connecting cavity.

[0009] In one embodiment of this application, the support structure further includes a mounting ring, an adjusting plate, and a connecting rod. The mounting ring is fixedly connected to the inner wall of the connecting hole, and one end face of the mounting ring is flush with the inner wall of the mold groove. The adjusting plate is slidably connected to the inner wall of the connecting hole, and the surface of the adjusting plate is provided with evenly distributed ventilation holes. The connecting rod is fixedly connected to one end of the adjusting plate, and the other end of the connecting rod passes through the mounting ring.

[0010] In one embodiment of this application, a second spring is fixedly connected to the surface of the adjusting plate, and the other end of the second spring is fixedly connected to the surface of the mounting ring.

[0011] In one embodiment of this application, a through groove is formed on the surface of the connecting rod.

[0012] In one embodiment of this application, the auxiliary structure includes a lead screw, a guide rod, a slider, a first motor, and a cutting wheel. One end of the lead screw is rotatably connected to the inner side of the support frame, and the other end of the lead screw passes through the support frame and is equipped with a second motor.

[0014] In one embodiment of this application, a check valve is provided on the inner wall of both the connecting pipe and the gas injection pipe.

[0015] Compared with the prior art, the beneficial effects of this application are as follows: 1. Through the cooperation of the bending structure and the support structure, after processing, the second mold is separated first by the spring reset, breaking the binding and adsorption between the workpiece and the upper mold. On the support structure, the workpiece is smoothly ejected from the lower mold by the dual action of air pressure difference and spring push rod. This dual demolding design avoids the manual knocking and prying required in the traditional process, which not only protects the workpiece surface from damage, but also improves demolding efficiency, eliminates operational safety hazards, and realizes automated and non-destructive separation.

[0016] 2. By using an auxiliary structure to pre-cut grooves in the steel plate before bending, a deformation space is provided for bending, which fundamentally reduces the risk of microcracks or fractures caused by high stress concentration. The electric heating tubes in the support structure can heat the steel plate and the injected gas, which enhances the plasticity of the steel plate and makes bending smoother. This further eliminates residual stress inside the material, thereby significantly improving the quality of bending and the first-pass yield of the product.

[0020] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0021] The steel structure connector bending processing equipment of this application embodiment will be described below with reference to the accompanying drawings.

[0022] like Figure 1-6 As shown, the steel structure connector bending processing equipment of this application embodiment may include a base plate 1, a support frame 101, a bending structure 2, a support structure 3, and an auxiliary structure 4.

[0023] The support frame 101 is fixedly connected to the top of the base plate 1, the support structure 3 is fixedly connected to the top of the base plate 1, the bending structure 2 is fixedly connected to the top of the support frame 101, and the auxiliary structure 4 is located on the inner side of the support frame 101.

[0024] The bending structure 2 may include a hydraulic push rod, a mounting plate 201, an adjusting rod 202, two first pressing molds 204 and a second pressing mold 205.

[0025] The hydraulic push rod is fixedly connected to the top of the support frame 101. The mounting plate 201 is located inside the support frame 101. The output shaft of the hydraulic push rod passes through the support frame 101 and is fixedly connected to the top of the mounting plate 201. A connecting frame is fixedly connected to the bottom of the mounting plate 201. Two first molds 204 are fixedly connected to the bottom of the connecting frame and are symmetrically distributed. A second mold 205 is slidably connected between the two first molds 204. The lower end of the adjusting rod 202 is connected to the top of the first mold 204. The upper end of the adjusting rod 202 passes through the connecting frame and the mounting plate 201 in sequence. A fixing ring is fixedly connected to the surface of the adjusting rod 202. A first spring 203 is fixedly connected to the top of the fixing ring. The upper end of the first spring 203 is fixedly connected to the bottom of the mounting plate 201. The lower end of the first spring 203 is fixedly connected to the inner side of the connecting frame.

[0026] Specifically, the hydraulic push rod can push the mounting plate 201 downward, thereby synchronously driving the connecting frame, the first pressure mold 204, and the second pressure mold 205 to move downward simultaneously. During this process, the second pressure mold 205 first contacts the surface of the steel plate, thereby sliding upward between the two first pressure molds 204. At the same time, it can drive the adjusting rod 202 upward to move the fixing ring upward synchronously, thereby squeezing the first spring 203. After the bending process is completed, during the process of the mounting plate 201 being driven upward by the hydraulic push rod, the second pressure mold 205 is driven to separate from the first pressure mold 204 under the action of the first spring 203, thereby forming a segmented separation effect, avoiding the situation where the steel plate after squeezing and bending is tightly attached to the surface of the pressure mold, which is not conducive to separation.

[0027] In one embodiment of this application, such as Figure 3 As shown, the support structure 3 may include a support block 301, an air injection pipe 308, and an electric heating pipe 306.

[0028] The support block 301 is fixedly connected to the top of the base plate 1, and a mold groove 302 is provided on the top of the support block 301. A connecting cavity 305 is provided inside the support block 301. An electric heating tube 306 is fixedly connected to the inside of the connecting cavity 305. An air injection pipe 308 is provided on one side of the support block 301 and communicates with the connecting cavity 305. The inner wall of the mold groove 302 is provided with evenly distributed mounting cavities 303. The inner wall of the mounting cavity 303 is provided with a connecting hole 304 that communicates with the connecting cavity 305.

[0029] Specifically, the steel plate to be bent is placed on top of the support block 301 to block the mold groove 302. The air injection pipe 308 is used to inject clean air. The introduced clean air can be heated by the electric heating tube 306 and then discharged through the connection hole 304 and the mounting cavity 303 to heat the bottom of the placed steel plate. At the same time, due to the blocking of the steel plate, the injected gas can stay inside the mold groove 302, making its internal air pressure greater than the external air pressure. Therefore, after bending, the product can be separated under the action of air pressure difference.

[0030] In one embodiment of this application, such as Figure 4 As shown, the support structure 3 may also include a mounting ring 309, an adjusting plate 313, and a connecting rod 307.

[0031] The mounting ring 309 is fixedly connected to the inner wall of the connecting hole 304. One end face of the mounting ring 309 is flush with the inner wall of the mold groove 302. The adjusting plate 313 is slidably connected to the inner wall of the connecting hole 304. The surface of the adjusting plate 313 is provided with evenly distributed vent holes 312. The connecting rod 307 is fixedly connected to one end of the adjusting plate 313, and the other end of the connecting rod 307 passes through the mounting ring 309. A second spring 311 is fixedly connected to the surface of the adjusting plate 313. The other end of the second spring 311 is fixedly connected to the surface of the mounting ring 309. The surface of the connecting rod 307 is provided with a through groove 310.

[0032] Specifically, the second spring 311, in conjunction with the adjusting plate 313, allows the connecting rod 307 to pass through the mounting ring 309 under normal conditions, facilitating gas injection into the mold groove 302. During bending, the steel plate, when pressed against the inner wall of the mold groove 302, can compress the connecting rod 307 and retract it into the mounting cavity 303. After processing, the second spring 311 can drive the connecting rod 307 to reset, and with the air pressure in the mounting cavity 303 being greater than the external air pressure, the product is quickly lifted, making it easy for workers to remove.

[0033] In one embodiment of this application, such as Figure 6 As shown, the auxiliary structure 4 may include a lead screw 401, a guide rod 403, a slider 402, a first motor 404, and a cutting wheel 406.

[0034] One end of the lead screw 401 is rotatably connected to the inner side of the support frame 101, and the other end of the lead screw 401 passes through the support frame 101 and is equipped with a second motor. The output shaft of the second motor is fixedly connected to the end of the lead screw 401. The slider 402 is threadedly connected to the surface of the lead screw 401. One end of the guide rod 403 is fixedly connected to the inner wall of the support frame 101, and the other end of the guide rod 403 passes through the slider 402 and is fixedly connected to the inner wall of the support frame 101. The first motor 404 is fixedly connected to one side of the slider 402, and the output shaft of the first motor 404 is fixedly connected to a rotating shaft. The cutting wheel 406 is fixedly connected to the other end of the rotating shaft. The surface of the slider 402 is fixedly connected to an exhaust pipe 405, and the surface of the exhaust pipe 405 is connected to a connecting pipe 407. The other end of the connecting pipe 407 is connected to the connecting cavity 305. Check valves are provided on the inner walls of both the connecting pipe 407 and the air injection pipe 308.

[0035] Specifically, by starting the second motor, the lead screw 401 can be rotated, thereby causing the slider 402 to move. Before bending, the first motor 404 and the second motor can be started to drive the cutting wheel 406 to cut the surface of the placed steel plate, forming a groove. Thus, the bending of the steel plate is achieved through the cooperation of the bending structure 2 and the support structure 3. Furthermore, the groove reduces the stress during the processing and provides deformation space to prevent breakage.

[0036] The connecting pipe 407 allows heated air to be discharged through the exhaust pipe 405 during the cutting process, which can blow the debris generated during cutting away from the surface of the steel plate and heat the surface of the steel plate. The heated steel plate can be bent better, reducing the stress caused by direct bending.

[0037] Specifically, the working principle of this application is as follows: Bending principle: The auxiliary structure 4 pre-treats the surface of the steel plate to form a groove, which reduces stress concentration during the bending process, provides deformation space for the steel plate to bend, and prevents breakage during bending. Then, the bending structure 2 and the support structure 3 work together to bend the placed steel plate.

[0038] Separation principle: After the bending process is completed, under the action of the bending structure 2, the second mold 205 can actively separate from the first mold 204, reducing the adhesion force and facilitating product demolding. At the same time, the second spring 311 is released, pushing the adjusting plate 313 and the connecting rod 307 to reset. The connecting rod 307 extends from the mounting ring 309 and directly lifts the product, making the product quickly separate from the mold groove 302. Furthermore, since the internal air pressure of the mounting cavity 303 is greater than the external air pressure, an outward thrust is formed, which further improves the separation efficiency of the product and makes it easier for the staff to remove it.

[0039] In summary, the steel structure connector bending processing equipment of this application embodiment can achieve rapid separation of the product and the mold after bending the steel structure connector, thereby effectively protecting the workpiece surface, improving demolding efficiency and product qualification rate.
