Description

Technical Field

[0001] This utility model belongs to the technical field of automotive parts processing equipment, specifically relating to an automotive parts punching and trimming die. Background Technology

[0002] Automotive parts processing comprises various units and products that serve the overall automotive parts processing industry. As the foundation of the automotive industry, automotive parts are a necessary factor supporting its continued healthy development. During the production of automotive parts, punching and trimming are required. Existing automotive parts trimming dies generally require workers to manually place the cut automotive parts into the positioning slot of the lower die base and then fix them. Grinding equipment is then used to trim the workpiece. Firstly, manually placing the workpiece inside the equipment can be dangerous. Secondly, after each trimming, the workpiece needs to be removed and replaced with a new one, resulting in long downtime and reduced work efficiency.

[0003] To address this, a stamping and trimming die for automotive parts, with announcement number "CN221755548U", includes a base and a frame welded and fixed to the rear side of the base. Two sets of sliding strips are fixed to the bottom of the base, and a collection groove is inserted into the base behind the sliding strips. Both sides of the two sets of sliding strips are slidably connected to a base plate. A housing is fixed to the upper part of the base plate, and a rotary motor is fixed inside the housing. The upper output shaft of the rotary motor passes through the housing and is fixed to a sleeve. A telescopic column is connected inside the sleeve via a spring. The upper part of the telescopic column extends to the upper side of the sleeve and is fixed to a fixing plate. Four sets of suction cups are fixed to the fixing plate. An electric push rod is fixed to the rear side of the frame. The front telescopic end of the electric push rod passes through the frame and is fixed to a bracket. A grinding motor is fixed inside the bracket. This design reduces downtime, improves work efficiency, and allows for the collection of generated debris.

[0004] However, for the aforementioned automotive parts punching and trimming die, although the workpiece is placed on two sets of fixed plates and pressed down to be initially adsorbed and positioned by the suction cup 13, and then the workpiece is rotated by one of the conveyor motors driven by the controller, the following obvious defects still exist in the use of the die: the above-mentioned die uses upper and lower clamps to fix the workpiece and uses the suction cup to adsorb and fix it to achieve positioning and rotation. During the rotation, the high-speed rotation of the workpiece will cause the vibration to cause the suction cup to adsorb the workpiece at the edge, resulting in air leakage. This will cause the suction cup to detach from the workpiece adsorption surface, resulting in the workpiece becoming loose and being thrown out. Utility Model Content

[0025] 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.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a stamping and trimming die for automotive parts, comprising:

[0027] Trimming groove 1, with a rotating trimming disc 3 for adjusting trimming of workpieces of different diameters via a fixed shaft 2 on the inner side of trimming groove 1. Trimming groove 1 is the basic structure of the entire mold, providing installation space and working area for other components. The rotating trimming disc 3 installed on its inner side, as well as the related adjustment and trimming components, all rely on the trimming groove 1. The fixed shaft 2 is fixed to the top of the support column 6, which not only provides the rotating trimming disc 3 with a central axis of rotation, but also allows the rotating trimming disc 3 to rotate smoothly through the bearing 10 sleeved on its outside. The rotating trimming disc 3 is evenly slidably provided with trimming rollers 4 that are adjusted according to the diameter of the workpiece. The upper end of the fixed shaft 2 is provided with a workpiece placement plate 5 for horizontally placing the workpiece. In addition, it also supports the workpiece placement plate 5 above, ensuring the stability of the workpiece when it is horizontally placed, and providing a stable foundation for subsequent trimming operations. The strip grooves 13 evenly opened at the end of the rotating trimming disc 3 cooperate with the adjusting cylinder 20 and the limiting slider 14 to flexibly adjust the position of the trimming rollers 4 according to the diameter of the workpiece to adapt to the trimming requirements of different workpieces.

[0028] The workpiece placement tray 5 is located at the upper end of the fixed shaft 2, providing a horizontal platform for the workpiece. It ensures the accurate initial position of the workpiece before trimming, allowing the workpiece to be stably placed on the mold, facilitating subsequent pressing and fixing via the positioning plate 9 and the smooth progress of trimming operations.

[0029] The support column 6, located at the center of the bottom inner side of the trimming groove 1, is a crucial support structure for the entire mold. It not only stably supports the upper fixed shaft 2, rotating trimming disc 3, and workpiece placement disc 5, ensuring their stability during operation, but also provides a mounting position for the drive motor 11 and drive gear 7. This allows the drive motor 11 to drive the rotating trimming disc 3 via the drive gear 7, achieving trimming of the workpiece. One side of the support column 6 has drive gear 7 that drives the rotating trimming disc 3 to rotate and trim the workpiece using the trimming roller 4. The drive gear 7 is mounted on the shaft of the drive motor 11 and meshes with the internal teeth of the drive ring 12 at the lower end of the rotating trimming disc 3, transmitting power. It transmits the rotational power output from the drive motor 11 to the rotating trimming disc 3, enabling it to rotate at a set speed, thereby driving the trimming roller 4 to trim the workpiece.

[0030] The support column 6 is located at the center of the bottom of the inner side of the trimming groove 1, and the end of the trimming groove 1 is pneumatically telescopically provided with a positioning pressure plate 9 for pressing down and fixing the placed workpiece through the fixed bracket 8.

[0031] The fixed shaft 2 is fixed to the top of the support column 6, and the fixed shaft 2 is sleeved with a bearing 10 that rotates through the rotating trimming disc 3. The rotating trimming disc 3 can rotate smoothly through the bearing 10 sleeved on its outside.

[0032] A drive motor 11 is located on one side of the supporting column 6, and drive gears 7 are mounted on the rotating shaft of the drive motor 11. The drive motor 11 is the power source for the entire mold trimming operation. It provides power for the rotation of the rotating trimming disc 3, and drives the rotating trimming disc 3 to rotate through the meshing of the drive gears 7 on the rotating shaft with the drive ring 12. The drive motor 11 has good speed regulation performance, and the operator can precisely adjust its speed according to the material, shape and trimming requirements of different workpieces to meet different trimming process requirements and ensure trimming quality and efficiency.

[0033] The lower end of the rotating trimming disc 3 is provided with a drive ring 12 with internal teeth, and the internal teeth of the drive ring 12 mesh with the drive teeth 7 on the drive motor 11. The drive ring 12 is located at the lower end of the rotating trimming disc 3, and its internal teeth are tightly meshed with the drive teeth 7 on the drive motor 11. It serves as a power transmission medium between the rotating trimming disc 3 and the drive teeth 7, effectively transmitting the power of the drive motor 11 to the rotating trimming disc 3, enabling the rotating trimming disc 3 to rotate stably.

[0034] The rotating trimming disc 3 has evenly spaced slots 13 at its ends, providing a track for the installation and sliding of the adjusting cylinders 20 and the limiting sliders 14. This design limits the movement direction of the limiting sliders 14, ensuring they can only slide within the slots 13 in a specific direction, thus guaranteeing the accuracy and stability of the trimming roller 4's position adjustment. This design allows for precise adjustment of the trimming roller 4's position according to the workpiece diameter, enabling trimming operations on workpieces of different sizes. Adjusting cylinders 20 are installed within each slot 13, controlling the sliding of the limiting sliders 14 within the slots through extension and retraction, thereby achieving rapid and precise adjustment of the trimming roller 4's position. The operator can control the extension and retraction of the adjusting cylinders 20 according to the workpiece's diameter using the control system.

[0035] Furthermore, a limiting slider 14, which slides within the strip groove 13, is fixed to one end of the adjusting cylinder 20. One end is fixed to the adjusting cylinder 20, and the other end engages with the positioning post 16 at the bottom of the outer fixed plate 15 of the trimming roller 4 via a positioning groove 17. Driven by the adjusting cylinder 20, it moves along the strip groove 13, thereby adjusting the position of the trimming roller 4. The sliding of the limiting slider 14 within the strip groove 13 provides excellent guidance, ensuring the stability and accuracy of the trimming roller 4 during movement and preventing trimming quality problems caused by positional deviations of the trimming roller 4.

[0036] The trimming roller 4 has a fixed upright plate 15 on its outer side, and a positioning post 16 at the bottom of the fixed upright plate 15. The end of the limiting slider 14 has a positioning groove 17 for inserting the positioning post 16 into the positioning groove. After the fixed upright plate 15 is positioned, it is fixed to the upper end face of the limiting slider 14 with screws. The trimming roller 4 directly acts on the workpiece to perform trimming operation. It is connected to the limiting slider 14 through the outer fixed upright plate 15. Specifically, the positioning post 16 at the bottom of the fixed upright plate 15 is inserted into the positioning groove 17 at the end of the limiting slider 14 and then fixed with screws. This connection method ensures the accuracy and stability of the installation of the trimming roller 4 and facilitates replacement and maintenance when the trimming roller 4 is worn or damaged.

[0037] A fixed bracket 8 is installed on the upper end of the trimming groove 1, and a telescopic cylinder 18 is provided on the inner top of the fixed bracket 8. The lower end of the telescopic cylinder 18 is fixed to the upper surface of the positioning pressure plate 9. The telescopic movement controls the up and down movement of the positioning pressure plate 9, pressing down and fixing the workpiece placed on the workpiece placement tray 5. The pressure of the telescopic cylinder 18 can be precisely adjusted according to the material and shape of the workpiece, ensuring that the workpiece is firmly fixed without causing damage due to excessive pressure. At the same time, its fast response speed enables the positioning pressure plate 9 to quickly press down and lift.

[0038] The rotating trimming disc 3 is uniformly perforated at its end with a material discharge screen 19 that allows the waste generated during trimming to fall into the trimming trough 1 for collection. The trimming trough 1 also serves to collect the waste generated during the trimming process. Through the material discharge screen 19, the waste can fall into the trimming trough 1, making it easy to clean and process, and maintaining the cleanliness of the working environment.

[0039] Specifically, during use, the workpiece is placed on the workpiece placement tray 5 located at the upper end of the fixed shaft 2. This platform ensures that the workpiece is placed horizontally and accurately. Subsequently, the telescopic cylinder 18 at the top inner side of the fixed bracket 8 at the end of the trimming groove 1 is activated, controlling the positioning pressure plate 9 to press down, applying pressure evenly to the workpiece and firmly fixing it, ensuring that the workpiece does not shift or shake during the trimming process. The drive motor 11 on one side of the support column 6 serves as the power source, and the drive teeth 7 on its rotating shaft are tightly engaged with the drive ring 12 with internal teeth at the lower end of the rotating trimming disc 3. After the drive motor 11 starts, it transmits rotational power to the drive ring 12 through the drive teeth 7, thereby driving the rotating trimming disc 3 to rotate stably. The operator can precisely adjust the speed of the drive motor 11 according to the material, shape, and trimming requirements of different workpieces by utilizing its excellent speed regulation performance.

[0040] Subsequently, an adjusting cylinder 20 is installed in the evenly spaced strip grooves 13 at the end of the rotating trimming disc 3. A limiting slider 14 fixed at one end of the cylinder 20 can slide within the strip grooves 13. Based on the workpiece diameter, the operator controls the extension and retraction of the adjusting cylinder 20 through the control system, causing the limiting slider 14 to move in a specific direction within the strip grooves 13, thereby precisely adjusting the position of the trimming roller 4. The fixed upright plate 15 on the outer side of the trimming roller 4 is inserted into the positioning groove 17 at the end of the limiting slider 14 via a bottom positioning post 16 and fixed with screws, ensuring accurate and stable installation and facilitating replacement and maintenance when the trimming roller 4 is worn or damaged. When the rotating trimming disc 3 rotates, the trimming roller 4 performs trimming operations on the fixed workpiece. Waste chips generated during the trimming process fall into the trimming groove 1 below through the evenly spaced discharge screen 19 at the end of the rotating trimming disc 3. The trimming groove 1 serves to collect waste chips, facilitating centralized cleaning and maintaining a clean working environment.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
