Description

Technical Field

[0001] The present invention belongs to the technical field of hanger production equipment, and particularly relates to a cold bending forming device for garage door hangers. Background Art

[0002] A cold bending forming device for garage door hangers is a mechanical equipment specifically used for producing garage door hangers and other metal components. The garage door hanger is a key load-bearing component in the garage door system, usually made of metal materials such as steel. Its main function is to support and bear the weight of the garage door, ensuring the normal opening and closing of the garage door. Therefore, the strength, dimensional accuracy, and stability of the hanger are crucial for the long-term use safety of the garage door. During the production process, precise cold bending forming technology is required to process metal sheets. Cold bending forming is a process of applying external force to metal sheets at room temperature to cause plastic deformation, usually used for manufacturing metal components with high precision and surface quality. Compared with traditional hot forming processes, cold bending forming has the advantages of low energy consumption, high production efficiency, and small material waste.

[0003] There is currently disclosed a cold bending forming device with the publication number of CN221434650U, which includes a workbench. A chute is opened on the right side of the top of the workbench. The lower side of the bottom end of a limiting clamp block is fixedly connected to the rear side of the top of the chute. A right semi-circular groove is opened at the center of the front end of the limiting clamp block. The rear side of the moving clamp block is sleeved on the front end of the limiting clamp block. A left semi-circular groove is opened at the center of the rear side of the moving clamp block; the right semi-circular groove and the left semi-circular groove are fitted at the center to place the right side of the bending roller. The bottom end of the support frame in the lifting mechanism is fixedly connected to the right side of the top of the workbench. Auxiliary rods are fixedly arranged on both inner walls of the support frame. Cross bars are arranged on both sides of the bottom end of the auxiliary rods, which can quickly disassemble damaged components of the cold bending machine to further improve efficiency, and can quickly replace them to save maintenance time, improve work efficiency, reduce the work burden of operators, and further improve the replacement and maintenance efficiency.

[0004] In actual operation, for hangers with different widths and process requirements, when operators place the hanger to be processed on the feeding rack, they must ensure the precise docking of the strip steel with the feeding device. This step is crucial for the quality of cold bending forming. However, it is difficult for the above device to maintain the position of the hanger during the transmission process and difficult to meet the requirements of hangers with different widths and process needs. Due to the diversity of finished products and the complexity of process requirements, there may be significant differences in the widths of hangers. Some narrower hangers may slide or shift in the fixing device, while wider hangers may be restricted by the fixing device, resulting in incomplete fitting or incorrect positioning. In addition, according to different process requirements, the strip steel may need to be adjusted or offset to different degrees during the transmission process. Therefore, it needs to be improved and optimized. Summary of the Invention

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] As Figures 1 to 8 shown, the present invention provides a cold bending forming device for a garage door hanger, including:

[0033] The mounting frame 1, the mounting frame 1 is designed with two layers, and the support columns of the mounting frame 1 are fixedly installed with cross bars to maintain stability;

[0034] The cold bending roller frame 2 is fixedly installed on the top of the mounting frame 1 by bolts. There are several groups of cold bending roller frames 2, which are designed to be linearly arranged and are used for cold bending forming operations on the hanging frame. Each cold bending roller frame 2 is composed of two cold bending rollers, and the two cold bending rollers are installed corresponding to each other up and down. The cold bending roller located below is fixedly connected to the cold bending roller frame 2, and the cold bending roller located above is set to be threadedly installed with adjustable height to adapt to hanging frames of different sizes.

[0035] A guiding mechanism is provided on the top of the mounting frame 1. The guiding mechanism includes a driving component and a transmission component. The driving component is used to provide the power for adjustment to the transmission component, and the transmission component is used to limit and guide the hanging frame to prevent it from sliding or shifting during the cold bending operation. The driving mechanism includes a hydraulic cylinder 5 fixedly installed at the bottom of the mounting frame 1. A rack 501 is fixedly installed on the output of the hydraulic cylinder 5. By driving the output shaft of the hydraulic cylinder 5, the rack 501 is driven to move. The rack 501 is designed in an L shape. Its short side is fixedly connected to the output shaft of the hydraulic cylinder 5, and its tooth grooves are opened on the outer wall of the long side of the rack 501. A limiting slide bar 102 is fixedly installed at the bottom of the mounting frame 1. The limiting slide bar 102 penetrates through the rack 501 and is slidably connected to the rack 501 to limit the rack 501 during movement.

[0036] Adopting the above scheme: By designing the mounting frame 1 as a two-layer structure and fixedly installing a cross bar on the support column, which mainly plays a role in providing overall stability, not only enhances the structural strength of the device, but also can effectively share the load generated during equipment operation. Since relatively large mechanical stress may occur during the cold bending forming process, the combination of the support column and the cross bar of the mounting frame 1 keeps the device stable during operation, preventing the equipment from vibrating or shifting during operation. The cold bending roller frame 2 is composed of several linearly arranged cold bending roller groups. Each roller group is composed of two cold bending rollers. Among them, the lower cold bending roller is fixedly connected to the cold bending roller frame 2, and the upper cold bending roller is threadedly installed with adjustable height. Through this design, the cold bending roller frame 2 can adapt to hanging frames of different sizes, ensuring high precision and flexibility in the cold bending forming operation of the hanging frame. The adjustable upper cold bending roller enables the operator to make precise adjustments according to actual needs, thus meeting the forming requirements of hanging frames of different specifications.

[0037] Through the guiding mechanism provided at the top of the mounting frame 1, which includes a driving component and a transmission component, it is responsible for the precise guiding of the hanging frame during the cold bending operation. The driving component is composed of a hydraulic cylinder 5 fixedly installed at the bottom of the mounting frame 1. The hydraulic cylinder 5 provides powerful power to drive the movement of the rack 501. The L-shaped design of the rack 501 enables it to move more stably during the operation. The design of the tooth grooves ensures the smooth sliding connection between the rack 501 and the first limiting slide bar 102, preventing the rack 501 from shifting during work. As the driving component, the hydraulic cylinder 5 drives the movement of the rack 501 through the output shaft and can provide precise power adjustment. The output of the hydraulic cylinder 5 is fixedly connected to the short side of the rack 501, and the tooth grooves of the rack 501 play a guiding role in the connection with the first limiting slide bar 102. The application of the hydraulic system enables the entire system to still operate smoothly when bearing a large load, avoiding the unstable operation of the equipment caused by external forces. In addition, the power output of the hydraulic cylinder 5 can achieve very fine adjustment, ensuring the efficient execution of the limiting and guiding functions for the hanging frame.

[0038] As Figures 4 to 6 shown, the transmission component includes two limiting bars 101 fixedly installed at the top of the mounting frame 1. A rotating rod 6 is arranged above the mounting frame 1. The rotating rod 6 penetrates through the mounting frame 1 and is rotatably connected to the mounting frame 1. A gear 601 and a mounting block 602 are fixedly sleeved on the outer wall of the rotating rod 6. The gear 601 is located below the mounting block 602, and the gear 601 and the mounting block 602 are distributed at the top and bottom of it. The gear 601 meshes with the rack 501. By moving the rack 501, the gear 601 can be driven to drive the rotating rod 6 to rotate. Two connecting rods 603 are hingedly installed on the inner walls of both ends of the mounting block 602. Two moving blocks 3 are respectively hingedly installed on the outer walls of the two connecting rods 603. Both moving blocks 3 are slidably connected to the two limiting bars 101. The sliding connection between the limiting bars 101 and the moving blocks 3 limits the moving path of the moving blocks 3.

[0039] Adopting the above scheme: Through the sliding connection between the limiting bars 101 and the moving blocks 3, it is ensured that the moving blocks 3 always remain within the predetermined moving path during the transmission process. By restricting the moving blocks 3, the moving path is not interfered by external factors, avoiding misoperation or deviation caused by external forces, thus ensuring the high precision and stability of the equipment during operation; The combination of the rotating rod 6 and the gear 601 provides a power transmission mechanism; The rotating rod 6 realizes power transmission through the meshing of the gear 601 and the rack 501, and drives the gear 601 to rotate through the sliding of the rack 501, thereby driving the rotating rod 6 to rotate; The function of the rack 501 is to convert linear motion into rotational motion, enabling the rotating rod 6 to perform precise rotational motion;

[0040] The mounting block 602 is connected to two connecting rods 603 in a hinged manner. The other ends of the connecting rods 603 are connected to two moving blocks 3 through hinges. The hinged design ensures that when the rotating rod 6 rotates, the mounting block 602 can drive the connecting rods 603 and the moving blocks 3 smoothly. The setting of the hinge points effectively avoids excessive wear and enhances the stability and flexibility of the movement. When the rotating rod 6 drives the gear 601 to rotate, the movement of the mounting block 602 is not only smooth, but also can effectively transmit the rotational power to the moving block 3, ensuring the precise movement of the moving block 3 during the working process.

[0041] As Figures 6 to 8 shown, adjusting components are respectively arranged on the outer walls of the two moving blocks 3. The adjusting component includes a guide plate 301 fixedly installed on the outer wall of the moving block 3. The moving block 3 is designed in an inverted T shape. A lead screw 302 is rotatably installed at the top of the short side of the moving block 3. The lead screw 302 passes through the guide plate 301 and is rotatably connected to the guide plate 301. An adjusting block 4 is threadedly sleeved on the outer wall of the lead screw 302. Two sets of guide wheel groups 401 are arranged at the bottom of the adjusting block 4, which are used to contact the hanging bracket during feeding to reduce friction. A limiting slide rod two 303 is fixedly installed on the outer wall of the moving block 3. The limiting slide rod two 303 passes through the adjusting block 4 and is slidably connected to the adjusting block 4, which is used to limit the movement of the adjusting block 4.

[0042] Adopting the above solution: The moving block 3 adopts an inverted T-shaped design, making its structure more stable; during the adjustment process, the horizontal width of the inverted T-shaped design can provide a larger support surface for the installation guide plate 301, ensuring smoother rotation of the lead screw 302 and avoiding inaccurate work caused by space limitations; the lead screw 302 passes through the guide plate 301 and is rotatably connected to the guide plate 301, which can effectively ensure the smooth movement of the adjustment block 4 along the lead screw 302; by rotating the lead screw 302, the up and down position of the adjustment block 4 can be accurately controlled to adapt to the hanger materials of different widths or processing requirements, thereby improving the flexibility and adaptability of production; the two groups of guide wheel sets 401 provided at the bottom of the adjustment block 4 can contact the hanger materials, reducing the friction force on the hanger during the feeding process; the guide wheel sets 401 enable the hanger to slide smoothly during the feeding process, avoiding the resistance generated by friction, reducing material wear and damage; in addition, the guide wheel sets 401 can also help keep the hanger on the correct track, thus ensuring the accuracy and continuity of the feeding process; the limiting slide rod two 303 is slidably connected to the adjustment block 4 and plays an important limiting role when the adjustment block 4 moves; the presence of the limiting slide rod two 303 effectively prevents the adjustment block 4 from exceeding the predetermined working range, thereby avoiding equipment damage or material position deviation caused by excessive adjustment; through the cooperation of the limiting slide rod, the safety of the adjustment process is ensured, and the failures or errors caused by improper operation are reduced; due to the design of the moving block 3 and the adjustment block 4, the position of the hanger can be adjusted according to the different widths of the hanger materials; this flexible adjustment mechanism and the working cooperation with the cold bending roller rack 2 can enable the materials to be accurately pressed when the hanger passes through the cold bending roller rack 2, achieving an ideal cold bending effect; the feeding system needs to ensure that the hanger materials can pass through smoothly, and the guide wheel sets 401 on the moving block 3 play a crucial role during the feeding process; the guide wheel sets 401 effectively reduce the friction between the materials and other mechanical components, making the feeding smoother; this design significantly reduces the damage of mechanical friction to the materials, improves the working efficiency at the same time, and reduces the equipment failures or downtime caused by friction.

[0043] The working principle and usage process of the present invention:

[0044] First, adjust the device according to the process requirements and the shape of the hanger. The staff first adjusts the cold bending roller at the upper part of the cold bending roller rack 2 to make it have a suitable distance from the cold bending roller at the lower part so that the hanging parts can pass through the cold bending roller rack 2 for cold bending operations normally;

[0045] After adjusting the cold bending roll stand 2, it is also necessary to adjust the two moving blocks 3. First, determine the distance between the two moving blocks 3 according to the width of the hanger material. By starting the hydraulic cylinder 5, the output shaft of the hydraulic cylinder 5 expands and contracts to drive the rack 501 to move in the X-axis direction along the axis of the limiting slide bar 102. Through the meshing of the rack 501 and the gear 601, the rotating rod 6 and the rotating rod 6 are driven to rotate. Through the articulated connection between the two connecting rods 603 and the mounting block 602, the corresponding moving blocks 3 are driven by the two connecting rods 603 to perform a linear motion of approaching or separating from each other on the outer wall of the limiting strip 101, so that the guide wheel sets 401 on the two moving blocks 3 can contact the hanger material and reduce the friction on the hanger during the feeding process through the roller design of the guide wheel sets 401. Since the cold bending roll at the upper part in the cold bending roll stand 2 has changed the vertical height, in order to make the hanger located in the middle of the adjusting block 4 and the guide plate 301, it is also necessary to adjust the adjusting block 4 and the guide wheel sets 401 in the vertical direction. The staff can rotate the lead screw 302. Through the threaded connection between the adjusting block 4 and the lead screw 302, the rotation of the lead screw 302 is converted into the vertical movement of the adjusting block 4 along the axis of the lead screw 302, so that the hanger can be located in the middle of the adjusting block 4 and the lead screw 302.
