Description
Technical Field
[0001] This utility model relates to the technical field of bending equipment, and specifically to a heating element bending mechanism. Background Technology
[0002] Mechanical bending or hot bending processes are widely used in metal heating elements such as stainless steel, aluminum, and nickel-chromium alloys. Among them, cold bending is suitable for rapid forming of thin plates, while hot bending achieves precise shaping of thick plates or high-strength metals through controlled heating. High-frequency induction heating-assisted bending technology further improves the bending accuracy and efficiency of ductile materials such as copper through uniform heating. Ceramic heating elements such as silicon carbide rods and PTC ceramics rely on high-temperature plastic deformation and achieve stable forming with high temperature resistance and corrosion resistance in environments above 1450℃ combined with special molds. The three-point / four-point bending test method provides standardized data support for mechanical performance evaluation. Carbon fiber heating elements retain the characteristics of lightweight and high energy efficiency through braiding, winding, and heat treatment, and achieve stable construction of complex shapes through voltage control of the shaping machine.
[0003] In the bending process of hardware parts, operators often need more time to complete preparation work due to a lack of equipment operation experience. During the bending process, they are prone to angular deviations or dimensional errors due to unfamiliarity with the movements. For example, they may repeatedly adjust the pressure parameters due to misjudging the material's springback characteristics, or even produce scrap due to operational errors, directly reducing the output of qualified products per unit time. At the same time, although experienced employees have certain experience, if they have not received standardized training, they may develop inefficient personal operating habits, such as adjusting the equipment by feel instead of following process standards, or retaining unnecessary auxiliary actions (such as repeatedly checking calibrated molds). These hidden wastes are difficult to eliminate naturally through experience accumulation. Instead, the solidification of personal habits limits the space for efficiency improvement. Even equipment downtime caused by novice operation errors or the hidden time loss accumulated by inefficient steps of experienced employees ultimately result in the overall production capacity not being fully released and the delivery cycle being extended. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a heating element bending mechanism. The workpiece can be quickly positioned via the positioning groove of the first bending module. The bending protrusion of the second bending module and the bending die groove are mechanically engaged, replacing the step of repeatedly checking the mold manually. The operator only needs to activate the drive assembly to complete the bending action, eliminating the need to rely on personal experience to adjust auxiliary actions, thus eliminating hidden time losses, releasing overall production capacity, and shortening the delivery cycle. A pressure sensor provides real-time feedback on the pressure data when the movable and fixed modules are engaged. The drive assembly parameters can be adjusted according to the pressure value to avoid workpiece deformation due to excessive pressure or incomplete bending due to insufficient pressure, replacing the traditional method of manual adjustment by feel and reducing the scrap rate. Two sets of guide rails are installed parallel on the base, with guide rail grooves and slider limit blocks slidably connected. The movable module slides smoothly along the preset direction of the guide rails via the slider, eliminating lateral offset that may occur during manual operation and ensuring that the bending protrusion of the second bending module and the bending die groove of the first bending module are strictly aligned, avoiding workpiece size errors caused by displacement deviation.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A heating element bending mechanism includes a base, a driving assembly on the base for providing bending driving force, a linkage assembly at the output end of the driving assembly for converting the power transmission of the driving assembly, and a bending module at one end of the linkage assembly for bending a workpiece. The bending module includes a fixed module on the base and a movable module that cooperates with the fixed module. A sliding assembly is provided below the movable module for guiding the movable module. The linkage assembly includes a gearbox at the output end of the driving assembly, a transmission gear inside the gearbox, and at least one driving rack meshing with the transmission gear. One end of the driving rack is fixedly connected to one side of the movable module.
[0006] The drive assembly includes a mounting base on the base, a rotary motor on one side of the mounting base, a rotary shaft at the output end of the rotary motor, and a bearing housing on the rotary shaft. One end of the rotary shaft passes through the bearing housing and is fixedly connected to the transmission gear via the gearbox. The mounting base is used to fix the rotary motor on the base. The rotary motor is used to provide rotational driving force. The rotary shaft is used to output the rotational driving force to the transmission gear. The bearing housing is used to limit the rotational shaft to the gearbox.
[0007] One side of the gearbox is fixedly connected to the mounting base, and the gearbox has at least one rack hole that penetrates the other side, with the drive rack passing through the rack hole.
[0008] One side of the drive rack is provided with a straight rack, which meshes with the transmission gear.
[0009] The fixing module includes a support base on the base, a support plate on the support base, a support rib on one side of the support plate, and a first bending module on the other side of the support plate. The support base is used to fix the support plate to the base, the support plate is used to fix the first bending module, and the support rib is used to strengthen the stability of the support plate.
[0010] The first bending module has a bending mold groove on one side, and pressure sensors are provided on both sides of the bending mold groove. The pressure sensors are used to provide feedback on the clamping pressure when the fixed module and the movable module perform the bending action.
[0011] The active module includes a connecting plate on the sliding component, a mounting block on the connecting plate, a reinforcing rib on one side of the mounting block, and a second bending module on the other side of the mounting block. The connecting plate is used to fix the mounting block, the mounting block is used to fix the first bending module, and the reinforcing rib is used to enhance the stability of the mounting block.
[0012] The second bending module has a bending protrusion on one side, which is used to cooperate with the bending die groove to perform the bending process of the workpiece.
[0013] The sliding component includes at least one guide rail disposed between the driving component and the bending module, and at least one slider disposed on the guide rail. The slider is used to cooperate with the guide rail to slide and guide the movable module of the bending module.
[0014] The mounting base includes a fixing block disposed on the base and a connecting block disposed on the fixing block. The connecting block has an opening and a support strip is provided in the middle of the opening.
[0015] The beneficial effects of this utility model are as follows: 1. The positioning groove of the first bending module can quickly position the workpiece. The bending protrusion of the second bending module and the bending die groove are mechanically engaged. The bending action can be completed by starting the drive component. There is no need to rely on personal experience to adjust auxiliary actions (such as repeated die calibration), which eliminates hidden time loss, releases overall production capacity, and shortens the delivery cycle. 2. Pressure sensor provides real-time feedback on the pressure data when the moving module and the fixed module are engaged. The parameters of the drive component can be adjusted according to the pressure value to avoid workpiece deformation due to excessive pressure or incomplete bending due to insufficient pressure.

Detailed Implementation
[0024] The present invention will be further described below with reference to the accompanying drawings: like Figure 1-7As shown, this utility model relates to a heating element bending mechanism, including a base 1, on which a driving component 2 is provided to provide bending driving force. A linkage component 3 is provided at the output end of the driving component 2 to convert the power transmission of the driving component 2. A bending module 4 is provided at one end of the linkage component 3 to bend the workpiece. The bending module 4 includes a fixed module 40 disposed on the base 1 and a movable module 41 cooperating with the fixed module 40. A sliding component 5 is provided below the movable module 41. The sliding component 5 is used to slide and guide the movable module 41; the linkage component 3 includes a gearbox 30 located at the output end of the drive component 2, a transmission gear 31 located in the gearbox 30, and at least one drive rack 32 meshing with the transmission gear 31, one end of the drive rack 32 being fixedly connected to one side of the movable module 41; the sliding component 5 includes at least one guide rail 50 located between the drive component 2 and the bending module 4, and at least one slider 51 located on the guide rail 50, the slider 51 being used to cooperate with the guide rail 50 to slide and guide the movable module 41 of the bending module 4.
[0025] like Figure 1 , 7 As shown, in some embodiments, two sets of guide rails 50 are installed in parallel on the base 1. The guide rails 50 are provided with slide grooves 500. Two sets of sliders 51 are slidably connected to one set of guide rails 50. The sliders 51 are provided with limiting blocks 510, and the limiting blocks 510 are slidably connected to the slide grooves 500.
[0026] like Figure 1-3 As shown, the drive assembly 2 includes a mounting base 20 on the base 1, a rotary motor 21 on one side of the mounting base 20, a rotary shaft 22 at the output end of the rotary motor 21, and a bearing seat 23 on the rotary shaft 22. One end of the rotary shaft 22 passes through the bearing seat 23 and is fixedly connected to the transmission gear 31 via the gearbox 30. The mounting base 20 is used to fix the rotary motor 21 on the base 1. The rotary motor 21 is used to provide rotational driving force. The rotary shaft 22 is used to output the rotational driving force to the transmission gear 31. The bearing seat 23 is used to limit the rotational shaft 22 to the gearbox 30. The mounting base 20 includes a fixing block 200 on the base 1 and a connecting block 201 on the fixing block 200. The connecting block 201 has an opening, and a support strip is provided in the middle of the opening.
[0027] like Figure 4 As shown, one side of the gearbox 30 is fixedly connected to the mounting base 20. The gearbox 30 has at least one rack hole 300 that passes through the other side, and the drive rack 32 passes through the rack hole 300. One side of the drive rack 32 has a straight rack 320, which meshes with the transmission gear 31.
[0028] like Figure 4 As shown, in some embodiments, the gearbox 30 further includes an upper housing 301 and a lower housing 302. The gearbox 30 has two sets of rack holes 300 on one side, and the drive rack 32 also has two sets. When the two sets of drive racks 32 are respectively inserted into the two rack holes 300, the side with the straight rack 320 is arranged opposite to each other so that the straight rack 320 meshes with the transmission gear 31 in the gearbox 30.
[0029] In some embodiments, under low-speed conditions, the transmission gear 31 has a Z ≥ 17. When a transmission gear 31 with Z = 20 is used, its pitch circle diameter d = m × Z = 50 mm can effectively distribute the load. When the rotational motor 21 rotates at n = 300 rpm, the transmission ratio i can be set to 15:1. At this time, the linear velocity of the spur rack 320 is v = π × m × Z × n / 60 ≈ π × 2.5 × 20 × 300 / 60 ≈ 785 mm / s, which meets the requirements for high torque operation. Slow bending process; under medium speed conditions, the number of gear teeth can be adjusted to Z=18, the pitch circle diameter d=36mm, and the rack linear speed is increased by reducing the diameter. When the motor n=800rpm, the transmission ratio is adjusted to 8:1, and the rack linear speed vv=π×m×Z×n / 60≈π×2×18×800 / 60≈1508mm / s, ensuring efficiency and control accuracy. The transmission gear 31 and the spur rack 320 are made of 20CrMnTi alloy steel.
[0030] like Figure 1-6 As shown, the fixing module 40 includes a support base 400 disposed on the base 1, a support plate 401 disposed on the support base 400, a support rib 402 disposed on one side of the support plate 401, and a first bending module 403 disposed on the other side of the support plate 401. The support base 400 is used to fix the support plate 401 to the base 1, the support plate 401 is used to fix the first bending module 403, and the support rib 402 is used to strengthen the stability of the support plate 401. One side of the first bending module 403 is provided with a bending die groove 4030, and pressure sensors 404 are provided on both sides of the bending die groove 4030. The pressure sensors 404 are used to provide feedback on the engagement of the fixing module 40. The fastening pressure of the moving module 41 when performing the bending action; the moving module 41 includes a connecting plate 410 on the sliding component 5, a mounting block 411 on the connecting plate 410, a reinforcing rib 412 on one side of the mounting block 411, and a second bending module 413 on the other side of the mounting block 411. The connecting plate 410 is used to fix the mounting block 411, the mounting block 411 is used to fix the first bending module 403, and the reinforcing rib 412 is used to strengthen the stability of the mounting block 411; one side of the second bending module 413 is provided with a bending protrusion 4130, which is used to cooperate with the bending die groove 4030 to perform the bending process of the workpiece.
[0031] In some embodiments, the first bending module 403 is provided with a positioning groove 4031 located on one side of the bending die groove 4030 to facilitate rapid positioning when bending the workpiece.
[0032] Working principle: The drive component 2 provides rotational power, which is converted into linear motion by the linkage component 3. The sliding component 5 then precisely guides the movable module 41. The bending of the workpiece is completed through the cooperation of the fixed module 40 and the movable module 41. In specific use, the rotary motor 21 is fixed on the mounting base 20 of the base 1 as a power source. Its output shaft 22 passes through the bearing seat 23 and is fixedly connected to the transmission gear 31 in the gearbox 30. When the rotary motor 21 starts, the rotating shaft 22 drives the transmission gear 31 to rotate synchronously. At this time, the drive rack 32 (which passes through the rack hole 300 of the gearbox 30) meshes with the transmission gear 31 and generates linear displacement under the action of gear meshing. Since one end of the drive rack 32 is fixedly connected to the connecting plate 410 of the movable module 41, Therefore, the linear motion of the drive rack 32 is directly transmitted to the movable module 41. The movable module 41 is slidably connected to the guide rail 50 on the base 1 through the slider 51 below it. The groove 500 of the guide rail 50 and the limiting block 510 of the slider 51 cooperate to ensure that the movable module 41 slides smoothly only in the preset direction and avoids displacement. As the movable module 41 moves, the bending protrusion 4130 of its second bending module 413 gradually approaches the bending mold groove 4030 of the first bending module 403 of the fixed module 40. When the two are fully engaged, the pressure sensors 404 located on both sides of the bending mold groove 4030 provide real-time feedback of the engagement pressure to ensure the accuracy and stability of the bending action. Finally, the workpiece to be processed is clamped between the bending protrusion 4130 and the bending mold groove 4030, and the bending process is completed under the cooperation of the two.
[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. Therefore, without departing from the design spirit of the present utility model, any equivalent changes or modifications made by those skilled in the art to the structure, features and principles of the present utility model should fall within the protection scope of the patent application of the present utility model.
