Description

Technical Field

[0001] This invention relates to a bending device, specifically a fence bending machine, belonging to the technical field of fence processing equipment. Background Technology

[0002] Guardrails, also known as fences, are industrial "protective fences." They are mainly used in residential areas, highways, commercial areas, and public places to protect personal safety and equipment. Guardrails are ubiquitous in our lives, and their shape and height vary in different areas. Nowadays, guardrails are sometimes made of mesh metal, which is used to create protective fences. When using them, the mesh needs to be bent so that the upper part of the mesh is tilted at a certain angle to achieve a better protective effect. A bending machine is used to bend the mesh.

[0003] For example, CN102672078B discloses a fence bending machine, which includes a base, a frame, a rotating shaft, a pressure plate, a rotating shaft position detection mechanism, a rotating shaft power unit, and at least two limiting mechanisms for limiting the fence to be bent. The frame is mounted on the base, the rotating shaft is mounted on the frame, the pressure plate is fixedly connected to the rotating shaft, and the limiting mechanisms are fixed to the frame. The rotating shaft power unit includes at least one rocker arm, a connecting piece, and a hydraulic cylinder connected to a hydraulic source. One end of the rocker arm is fixedly connected to the rotating shaft, the other end of the rocker arm is hinged to one end of the connecting piece, the other end of the connecting piece is fixedly connected to the free end of the piston rod of the hydraulic cylinder, and the other end of the hydraulic cylinder is hinged to the base. This fence bending machine can reduce the labor intensity of workers and improve bending efficiency.

[0004] For example, publication number CN210305231 U describes a fence panel bending machine, comprising a bending machine body and a fence panel support frame. The fence panel support frame is located behind the bending machine body. An operating box is fixedly installed on one outer surface of the bending machine body. Slide rails are bolted to both ends of the inner surface of the bending machine body, and sliding plates are movably installed on the slide rails. Several sets of hydraulic lifting columns are provided at the top of the inner part of the bending machine body, and the lower ends of the hydraulic lifting columns are fixedly connected to the upper end of the sliding plates. This fence panel bending machine, as described in this utility model, firstly, can limit the position of the sliding plates, preventing tilting due to collisions during long-term use; secondly, it can drive the fence panels to move, reducing the workload of operators, eliminating the need for multiple operators, and significantly reducing labor costs; and finally, it facilitates the replacement of different bending dies, leading to better application prospects.

[0005] For example, publication number CN214391746U discloses a fence mesh bending machine, including a bending frame. The upper surface of the bending frame is provided with a scale. The bending frame has a U-shaped opening structure, and a connecting rod is installed on the inner side of the opening end. A slide table is slidably installed inside the bending frame. A screw rod is threadedly installed on the side wall of the slide table. Both ends of the screw rod protrude from the slide table. The screw rod is rotatably connected to the connecting rod and the bending frame. The beneficial effects are: the reciprocating rotation of the bending rod and the bending rod allows for reciprocating bending of the fence mesh, making operation more convenient, greatly reducing the workload of the operator, and improving bending efficiency; moreover, the screw rod can press the fence mesh tightly onto the slide table, and by rotating the screw rod, the slide table can be moved. With the scale reference, the fence mesh can be accurately moved to the bending position, improving bending accuracy.

[0006] When in use, it greatly saves labor and has the advantage of high efficiency and speed in bending the fence. However, as modern fences have increasingly higher requirements for bending, some fences now bend at the top and sides to improve the protective effect, forming a Y-shaped structure. However, when using existing bending machines, it becomes impossible to operate and inconvenient to use. Moreover, since the fence is made of metal, there is a large stress during bending, which causes springback after bending, affecting the bending effect.

[0007] In view of this, the present invention is proposed. When in use, it can not only bend one side of the fence, but also easily bend the fence into a Y-shaped structure in one go. It is convenient to use and easy to operate, which can meet the current needs of fence bending, and helps to eliminate stress and improve the bending effect. Summary of the Invention

[0008] The purpose of this invention is to provide a fence bending machine to solve the above problems. When in use, it facilitates bending of the fence to both sides to form a Y-shaped structure, and facilitates the elimination of stress at the bending position, reduces the springback effect, and thus improves the bending effect.

[0009] This invention achieves the above-mentioned objective through the following technical solution: a fence bending machine includes a frame assembly, with a pressing component fixedly installed at one end of the frame assembly, and an auxiliary bending component fixedly installed on the other side of the pressing component. Pull-bending components are fixedly installed on both sides of one end of the pressing component on the frame assembly, with one end of the pull-bending component extending to one side of the auxiliary bending component. The middle position of the pull-bending component is located above the pressing component. The auxiliary bending component includes an upper pressing-bending component and a lower pressing-bending component, with the output ends of the upper pressing-bending component and the lower pressing-bending component staggered. The pressing component includes a fixed plate, with pressing cylinders fixedly installed above both ends of the fixed plate. An upper pressing plate is fixedly installed at one end of the pressing cylinder, and a fixing strip is fixedly installed on one side of both the fixing plate and the upper pressing plate. A heating wire is fixedly installed inside the fixing strip. The output end of the pressing cylinder is fixedly connected to the fixing plate, and the pressing cylinder is fixedly installed on the upper pressing plate. The auxiliary bending assembly is fixedly installed on the fixing plate. Notches are opened at both ends of one side of the upper pressing plate, and one side of the auxiliary bending assembly is slidably engaged with the notches on the upper pressing plate. In use, first adjust the staggered position between the output ends of the upper bending assembly and the lower bending assembly to meet the bending requirements of the fence, and then place the fence to be bent on the frame. In the body assembly, during processing, an opening is first cut at the end of the fence mesh that needs to be bent. The fence mesh is then conveyed through the frame assembly, allowing one end to pass through the pressing assembly. The pressing assembly then presses the fence mesh down. During pressing, the upper pressing plate is lowered by the pressing cylinder, pressing the fence mesh between the upper pressing plate and the fixing plate, thus pressing the fixing strip tightly against the fence mesh. The heating wire is then activated to heat the fixing strip and the fence mesh. Bending then occurs from the heated position, which not only improves the ease of bending but also eliminates stress after bending, preventing springback after processing. After heating, the auxiliary bending assembly is activated, causing the output ends of the upper and lower bending assemblies to alternately bend one end of the guardrail mesh to both sides. After bending, the auxiliary bending assembly is deactivated, and the height of the pull bending assembly is adjusted so that one end of the pull bending assembly is positioned between the two bent ends of the guardrail mesh. The pull bending assembly further bends the guardrail mesh, forming a Y-shaped structure. After bending, the output end of the pull bending assembly is adjusted to one side and to a higher position. The holding cylinder is activated, causing the upper holding plate to rise. The guardrail mesh continues to be output through the frame assembly, thus completing the bending process of the guardrail mesh.

[0010] Furthermore, the upper bending assembly includes a snap-fit ​​strip, which is fixedly installed on the upper surface of the fixed plate. The snap-fit ​​strip snaps into the inside of the notch. An upper sliding strip is fixedly installed on one side of the snap-fit ​​strip. Upper sliding blocks are evenly snapped onto the upper sliding strip. A first auxiliary cylinder is fixedly installed on one side of the upper sliding block. A first lifting seat is fixedly installed at the output end of the first auxiliary cylinder. A first bending shaft is rotatably installed inside the first lifting seat. The lower bending assembly includes a lower sliding strip, on which lower sliding blocks are evenly slidably snapped. The vertical positions of the upper and lower sliding blocks are staggered. A second auxiliary cylinder is fixedly installed on one side of the lower sliding block. A second lifting seat is fixedly installed at the output end of the second auxiliary cylinder. A second bending shaft is rotatably installed inside the second lifting seat. The upper sliding strip, the upper sliding block, and the upper sliding block are all fixedly installed. Both the lower sliding bar and the lower sliding block have threaded holes, and screws are threaded into the internal threads of the threaded holes. The upper sliding block is fixedly mounted on the upper sliding bar by the screws, and the lower sliding block is fixedly mounted on the lower sliding bar by the screws. During assisted bending, the positions of the upper sliding block and the lower sliding block on the upper sliding bar are adjusted to be staggered. During assisted bending, the first auxiliary cylinder and the second auxiliary cylinder are activated, so that the first bending shaft and the second bending shaft press the protective net and bend it on both sides to facilitate pre-bending. This causes one end of the protective net to form an angle due to bending on both sides, which facilitates further bending by the bending assembly, improves the bending effect, and facilitates the formation of a Y-shaped structure.

[0011] Furthermore, the frame assembly includes a conveyor frame, and the fixing plate is fixedly installed on one side of the conveyor frame. Through holes are provided on both sides of the middle position of the conveyor frame, and vertical plates are fixedly installed on both sides of the through holes on the lower surface of the conveyor frame. A rotating shaft is rotatably installed in the middle of the vertical plates. Conveyor wheels are fixedly installed at both ends of the rotating shaft, and levers are fixedly installed in a uniform circumferential array on the outer side of the conveyor wheels. One end of each lever passes through the through hole and extends to the upper end of the through hole. A drive motor is fixedly installed in the middle position of one side of the lower end of the conveyor frame, and a moving pulley is fixedly installed at the output end of the drive motor. A driven pulley is fixedly installed in the middle position of the rotating shaft. A belt is adjusted between the moving pulley and the driven pulley, and the drive motor drives the rotating shaft through the belt. The upper part of the conveyor frame... A groove is fixedly installed on one side of the through hole, and a bidirectional lead screw is rotatably installed inside the groove. Both ends of the bidirectional lead screw are threaded with positioning plates, and the positioning plates are L-shaped. The lower end of the positioning plate is engaged inside the groove. One end of the bidirectional lead screw extends to the outside of the conveyor frame, and a handwheel is fixedly installed on one end of the bidirectional lead screw. During conveying, the handwheel is turned first to adjust the distance between the positioning plates, thereby facilitating the limiting of both sides of the protective net and preventing the protective net from shifting during conveying. During conveying, the drive motor is turned on, and the rotating shaft rotates through the belt, thereby causing the conveyor wheel to drive the lever to rotate. The lever is inserted into the gap in the protective net, thereby facilitating the movement of the protective net on the conveyor frame for convenient conveying.

[0012] Furthermore, the bending assembly includes a fixing member, which is fixedly installed on both sides of the frame assembly. A lifting block is slidably engaged between the fixing members, and a bending cylinder is fixedly installed at one end of the lifting block. The output end of the bending cylinder passes through the lifting block and extends to the other side of the lifting block. A tensioning plate is fixedly installed at the output end of the bending cylinder, and a bending shaft is rotatably installed between the tensioning plates. The bending shaft is located on one side of the auxiliary bending assembly. A vertical groove is vertically formed in the middle of the fixing member, and the lifting block is slidably engaged inside the groove. A lifting plate is fixedly installed in the middle of the lifting block, and one side of the lifting plate is located directly above the upper pressure plate. Guide posts are fixedly installed on both sides of the upper surface of the upper pressure plate, and the lifting plate is sleeved on the guide posts. A connecting plate is fixedly installed at the upper end of the guide posts, and a servo is fixedly installed at the middle position of the upper surface of the connecting plate. The servo motor has a threaded rod fixedly installed at its output end, and the other end of the threaded rod is rotatably connected to the upper surface of the upper pressure plate. The threaded rod is threadedly connected to the lifting plate, which has a U-shaped structure and guide holes on both sides. The lifting plate is sleeved on the guide post through the guide holes, and a threaded tube is fixedly installed at the middle position of the upper surface of the lifting plate. The threaded rod is threadedly connected to the threaded tube. During bending, the servo motor drives the threaded rod to rotate, thereby causing the lifting plate to rise and fall along the threaded rod. This allows the lifting block to rise and fall within the sliding groove inside the fixed component, facilitating the adjustment of the bending shaft height. During bending, the bending cylinder is activated, causing the bending shaft to move in the direction of the frame assembly, facilitating further bending of the protective netting and making it convenient to use.

[0013] The technical effects and advantages of this invention are as follows: During use, the bending position is heated by the fixing strip and heating wire, thereby improving the bending effect and helping to eliminate stress at the bending position and prevent springback. Furthermore, by using auxiliary bending components, the fence mesh is bent at both sides in an alternating manner. Then, by using the bending assembly, the bending position of the fence mesh forms a Y-shaped structure, thereby meeting the current bending requirements of fence mesh and facilitating its use.

[0032] Please see Figure 1-9As shown, a fence bending machine includes a frame assembly 1, with a pressing assembly 2 fixedly installed at one end of the frame assembly 1, and an auxiliary bending assembly 3 fixedly installed on the other side of the pressing assembly 2. Bending assemblies 4 are fixedly installed on both sides of one end of the pressing assembly 2 on the frame assembly 1, with one end of the bending assembly 4 extending to one side of the auxiliary bending assembly 3. The middle position of the bending assembly 4 is located above the pressing assembly 2. The auxiliary bending assembly 3 includes an upper bending assembly 301 and a lower bending assembly 302, with the output ends of the upper bending assembly 301 and the lower bending assembly 302 staggered.

Notches 206 are provided at both ends of one side of the upper pressure plate 203, and one side of the auxiliary bending assembly 3 is slidably engaged with the notches 206 on the upper pressure plate 203. During use, the staggered position between the output ends of the upper bending assembly 301 and the lower bending assembly 302 is first adjusted to meet the bending requirements of the fence. The fence to be bent is then... The fence is placed on the frame assembly 1. During processing, an opening is first cut at the end of the fence that needs to be bent. The fence is then conveyed through the frame assembly 1, allowing one end to pass through the pressing assembly 2. The pressing assembly 2 then presses the fence down. During pressing, the upper pressing plate 203 is lowered by the pressing cylinder 202, pressing the fence between the upper pressing plate 203 and the fixing plate 201, and pressing the fixing strip 204 tightly against the fence. The heating wire 205 is then activated, heating the fixing strip 204 and the fence. Bending occurs from the heated position, which not only improves the bending efficiency but also eliminates stress after bending, preventing problems after processing. After the spring is generated and heated, the auxiliary bending component 3 is activated, so that the output ends of the upper bending component 301 and the lower bending component 302 alternately bend one end of the guardrail mesh to both sides. After bending, the auxiliary bending component 3 is closed, and the height of the pull bending component 4 is adjusted so that one end of the pull bending component 4 is located between the guardrail meshes that are bent to both sides. The guardrail mesh is further bent through the pull bending component 4, so that the guardrail mesh forms a Y-shaped structure. After bending, the output end of the pull bending component 4 is adjusted to one side and to a higher position. The pressure holding cylinder 202 is activated, so that the upper pressure holding plate 203 rises and continues to output the guardrail mesh through the frame component 1, thus completing the bending process of the guardrail mesh.

The upper sliding block 30103 is fixedly mounted on the upper sliding bar 30102 by the screws 6, and the lower sliding block 30202 is fixedly mounted on the lower sliding bar 30201 by the screws 6. During auxiliary bending, the position of the upper sliding block 30103 on the upper sliding bar 30102 is first adjusted, and the lower sliding block 30202 on the lower sliding bar 30201 is adjusted. The position on strip 30201 is such that the positions between the upper sliding block 30103 and the lower sliding block 30202 are staggered. When performing auxiliary bending, the first auxiliary cylinder 30104 and the second auxiliary cylinder 30203 are activated, so that the first bending shaft 30106 and the second bending shaft 30205 press the protective net and bend it on both sides, which facilitates pre-bending. Because one end of the protective net is bent on both sides, it forms an angle, which facilitates further bending by the bending assembly 4, improves the bending effect, and facilitates the formation of a Y-shaped structure.
