Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, and more specifically, to a stamping device for straightening metal sheets. Background Technology

[0002] In the production of electric motors, brush plates are used for electrical connection to transmit electrical energy to the motor rotor. Currently, during the manufacturing process of brush plates, metal sheets are installed on them for energy transmission. During the installation of these metal sheets, workers often use their hands to press them onto the brush plate's structure. However, when manually pressing the metal sheets, workers cannot apply even force, which can cause the sheets to shift due to uneven force. This reduces the stability of the metal sheets' connection within the brush plate, potentially leading to poor circuit contact during energy transmission. Therefore, we propose a stamping device for correcting the metal sheets. Utility Model Content

[0003] The purpose of this invention is to provide a stamping device for straightening metal sheets, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, one of the objectives of this utility model is to provide a stamping device for straightening metal sheets, including an assembly table. A manual press is fixedly mounted on the upper surface of the assembly table. An assembly mechanism is located directly below the press rod of the manual press. A linkage mechanism is provided on the outer side of the assembly mechanism and the press rod of the manual press. The assembly mechanism includes a lower mold fixed on the upper surface of the assembly table. A positioning groove is opened on the top of the lower mold. A movable groove is symmetrically opened on the bottom surface of the positioning groove. A flap is hinged to the outer end of the bottom surface of each of the two movable grooves. An assembly rod is fixedly mounted on the lower end of the press rod of the manual press. A V-groove is opened at the bottom of the assembly rod. When the press rod of the manual press moves vertically upward, the press rod drives the inner ends of the two flaps to flip upward synchronously through the linkage mechanism.

[0005] As a further improvement to this technical solution, the assembly mechanism also includes a housing that is slidably connected to the inner wall of the positioning groove. A metal conductive sheet is snapped into the inside of the housing, and the upper surfaces of the two flip plates abut against the lower surface of the housing.

[0006] As a further improvement to this technical solution, the linkage mechanism includes two upright frames fixed on the upper surface of the assembly table. Two sliders are slidably connected to the inner wall of the upright frames. An extension plate is fixed to the side wall of each slider. A rotating shaft is rotatably connected to the side wall of the upright frames. A gear is fixed to one end of the rotating shaft inside the upright frame, and a reset component is provided at the other end of the rotating shaft. Racks are meshed at the front and rear of the gear, and the outer ends of the two racks are fixed to the two sliders respectively. Two external plates are fixed to the outer wall of the manual press rod.

[0007] As a further improvement to this technical solution, the two lower extension plates abut against the upper surfaces of the two flip plates respectively, and the inner ends of the two upper extension plates are located directly above the two outer plates respectively. During the process of the manual press rod driving the two outer plates to move vertically upward, the two outer plates drive the two upper extension plates to move vertically upward respectively, and the two lower extension plates press the two flip plates respectively, causing the inner ends of the two flip plates to flip upward.

[0008] As a further improvement to this technical solution, the reset assembly includes a positioning ring fixed to the outer wall of the frame, and a coil spring is fixed between the outer circumferential wall of the rotating shaft and the inner circumferential wall of the positioning ring.

[0009] As a further improvement to this technical solution, two guide grooves are provided on the side wall of the upright frame, the slider is an I-shaped block, and the slider is slidably connected to the inner wall of the guide groove, the inner wall of the upright frame, and the outer wall.

[0010] As a further improvement to this technical solution, a snap-fit ​​component is fixedly provided on the bottom surface of the housing. The metal conductive sheet is snap-fitted and fixed on the top of the snap-fit ​​component. The assembly rod is located directly above the snap-fit ​​component. During the process of the manual press rod driving the assembly rod to move vertically downward, after the V-groove abuts against the metal conductive sheet, the inner wall of the V-groove finely adjusts the position of the metal conductive sheet to correct and correct its deviation, so that the metal conductive sheet is accurately snap-fitted and fixed with the snap-fit ​​component.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The stamping device for correcting metal sheets involves placing the metal conductive sheet on top of the snap-fit ​​component inside the housing, placing the housing inside the positioning groove, and then using a manual press rod to move the assembly rod vertically downwards. After the V-groove abuts against the metal conductive sheet, the inner wall of the V-groove fine-tunes the position of the metal conductive sheet, correcting and straightening it. The metal conductive sheet is then pressed to ensure accurate snap-fit ​​and fixation with the snap-fit ​​component, preventing poor circuit contact when the metal conductive sheet transmits electrical energy.

[0013] 2. The stamping device for straightening the metal sheet, after clamping and fixing the metal conductive sheet inside the housing, moves the manual press rod vertically upward. The manual press rod drives the inner ends of the two flip plates to flip upward synchronously through the linkage mechanism, so that the two flip plates push out of the positioning groove inside the housing. This avoids the electronic components on the surface of the housing from scratching the lower mold during the process of the worker taking the housing out of the positioning groove, which would cause damage to the brush plate.

[0023] 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 protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figures 1-4As shown, this embodiment provides a stamping device for straightening metal sheets, including an assembly table. A manual press 3 is fixedly mounted on the upper surface of the assembly table. An assembly mechanism 1 is located directly below the pressure bar of the manual press 3. A linkage mechanism 2 is provided on the outer side of the assembly mechanism 1 and the pressure bar of the manual press 3. The assembly mechanism 1 includes a lower mold 11 fixedly mounted on the upper surface of the assembly table. A positioning groove 12 is opened on the top of the lower mold 11. A movable groove 13 is symmetrically opened on the bottom surface of the positioning groove 12. A flap 14 is hinged to the outer end of the bottom surface of the two movable grooves 13. A housing 15 is slidably connected to the inner wall of the positioning groove 12. A metal conductive sheet 16 is provided inside the housing 15. The upper surfaces of the two flaps 14 abut against the lower surface of the housing 15. A snap-fit ​​component is fixedly mounted on the bottom surface of the housing 15. The metal conductive sheet 16 is snap-fitted and fixed to the top of the snap-fit ​​component. An assembly rod 17 is fixedly mounted on the lower end of the pressure bar of the manual press 3. A V-shaped groove 18 is opened at the bottom of the assembly rod 17. The assembly rod 17 is located directly above the snap-fit ​​component.

[0026] During the process of the worker pulling the lever of the manual press machine 3, the pressure rod of the manual press machine 3 moves the assembly rod 17 vertically downward. After the V-groove 18 abuts against the metal conductive sheet 16, the inner wall of the V-groove 18 finely adjusts the position of the metal conductive sheet 16, corrects and corrects the deviation of the metal conductive sheet 16, and makes the metal conductive sheet 16 accurately snap-fit ​​and fix it with the snap-fit ​​part. After the metal conductive sheet 16 is snap-fit ​​and fixed inside the housing 15, the pressure rod of the manual press machine 3 moves vertically upward. The pressure rod of the manual press machine 3 drives the inner ends of the two flip plates 14 to flip upward synchronously through the linkage mechanism 2, so that the two flip plates 14 push out the positioning groove 12 inside the housing 15, making it easy to remove the housing 15 from the lower mold 11.

[0027] In order to automatically drive the two flaps 14 to flip synchronously after the pressure bar of the manual press 3 moves vertically upward to a certain height, and to push the housing 15 with the metal conductive sheet 16 out of the positioning groove 12 as soon as possible, so as to achieve rapid unloading of the housing 15, the structure of the linkage mechanism 2 is refined. The linkage mechanism 2 includes two upright frames 21 fixed on the upper surface of the assembly table. Two sliders 22 are slidably connected to the inner wall of the upright frame 21. Extension plates 23 are fixed to the side walls of the two sliders 22. A rotating shaft 24 is rotatably connected to the side wall of the upright frame 21. A gear 25 is fixed to one end of the rotating shaft 24 located inside the upright frame 21. Furthermore, the other end of the rotating shaft 24 is provided with a reset component 29. When the outer plate 28 is not in contact with the upper extension plate 23, the reset component 29 restricts the rotation of the rotating shaft 24 and the gear 25 to prevent the lower extension plate 23 from applying pressure to the end of the flip plate 14 located outside the lower mold 11 under the action of gravity, causing the end of the flip plate 14 located directly above the lower mold 11 to tilt upwards, which would cause inconvenience to the placement of the housing 15. The gear 25 is meshed with racks 26 at the front and rear, and the outer ends of the two racks 26 are respectively fixed to the two sliders 22. The outer wall of the manual press 3 pressure rod is fixed with two outer plates 28.

[0028] The two lower extension plates 23 abut against the upper surfaces of the two flip plates 14, while the inner ends of the two upper extension plates 23 are directly above the two outer plates 28. As the manual press 3 moves the two outer plates 28 vertically upward, the two outer plates 28 lift the two upper extension plates 23 upward. The upper extension plates 23 move the upper slider 22 and one of the racks 26 vertically upward simultaneously. The rack 26 moves the other rack 26 vertically downward through the gear 25. The lower slider 22 and the lower extension plates 23 move vertically downward simultaneously, causing the two lower extension plates 23 to move closer to the flip plates 14. As the extension plates 23 move downward, they press the flip plates 14, causing the inner ends of the two flip plates 14 to flip upward.

[0029] To ensure the stability of both the upper and lower extension plates 23 when the outer plate 28 is not in contact with the upper extension plate 23, and to prevent the lower extension plate 23 from shifting downwards under gravity and prying the flap 14, thus disrupting its horizontal state, the structure of the reset assembly 29 is refined. The reset assembly 29 includes a positioning ring 291 fixed to the outer wall of the frame 21. A coil spring 292 is fixed between the outer circumference of the rotating shaft 24 and the inner circumference of the positioning ring 291. The coil spring 292 restricts the rotation of the rotating shaft 24 and the gear 25, thereby limiting the rotation of the gear. The positions of the strip 26, slider 22, and extension plate 23 are determined as follows: when the outer plate 28 lifts the upper extension plate 23 upward, the upper extension plate 23 drives the upper rack 26 to move synchronously, and the rotating shaft 24 drives the gear 25 to rotate, causing the coil spring 292 to elastically coil up. As the outer plate 28 moves downward until it disengages from the upper extension plate 23, the coil spring 292 rebounds. After the coil spring 292 returns to a stable state, it stabilizes the lower surface of the lower extension plate 23 at the same height as the upper surface of the flip plate 14, so that the flip plate 14 returns to a horizontal state.

[0030] The side wall of the upright frame 21 has two guide grooves 27. The slider 22 is an I-shaped block, and the slider 22 is slidably connected to the inner wall of the guide groove 27, the inner wall of the upright frame 21 and the outer wall. This allows the slider 22 to drive the extension plate 23 and the rack 26 to move vertically, ensuring stable meshing between the rack 26 and the gear 25.

[0031] In summary, the working principle of this solution is as follows: The metal conductive sheet 16 is placed on top of the snap-fit ​​component inside the housing 15. The housing 15 is then placed inside the positioning groove 12, restricting its horizontal movement on the lower mold 11. A worker pulls the lever of the manual press 3, causing the pressure rod of the manual press 3 to move the assembly rod 17 vertically downwards. During this downward movement, the V-groove 18 abuts against the metal conductive sheet 16. The inner wall of the V-groove 18 then fine-tunes the position of the metal conductive sheet 16, correcting and adjusting its alignment. Finally, the metal conductive sheet 16 is pressed down to ensure its accurate alignment. After the metal conductive sheet 16 is snapped into place inside the housing 15, the pressure rod of the manual press 3 is moved vertically upward. The pressure rod of the manual press 3 drives the inner ends of the two flaps 14 to flip upward synchronously through the linkage mechanism 2, so that the two flaps 14 push out of the positioning groove 12 inside the housing 15, making it easy to remove the housing 15 from the lower mold 11. The manual press 3 is a mature product that can be easily purchased on the market. A manual press of model YLJ-15T can be selected, but it is not limited to this. The worker only needs to pull the pull rod of the manual press 3 to control the vertical movement of the pressure rod.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
