Description

Technical Field

[0001] This utility model relates to the technical field of processing equipment for new energy vehicle parts, specifically a punching device for processing new energy vehicle parts. Background Technology

[0002] New energy vehicle components are all the detachable parts and assemblies that make up a complete new energy vehicle, and they work together to ensure the normal operation of the vehicle. Among new energy vehicle components, the oil seal base is a component used to install and fix the oil seal, providing support and positioning for the oil seal, ensuring that the oil seal maintains a stable position and shape during operation, thereby achieving its sealing function.

[0003] Oil seal seats are mainly manufactured through stamping, generally involving three processes: blanking, punching, and flanging. During the punching process, the oil seal base is typically placed within a positioning groove for fixation, preventing horizontal displacement of the oil seal seat during punching. However, this traditional fixing method has the following drawbacks: First, it is difficult to remove after punching: the stress generated during punching may cause slight elastic deformation of the oil seal seat or the positioning groove. After punching, this deformation cannot be fully recovered, creating an interference fit between the oil seal seat and the positioning groove, making it difficult to remove the oil seal seat smoothly from the groove. Second, there is a safety hazard: if the clamping force between the oil seal seat and the positioning groove is too great, the operator's hand may be trapped between the oil seal seat and the positioning groove when attempting to remove the oil seal seat, posing a risk of injury.

[0004] Therefore, this application provides a punching device for processing new energy vehicle parts to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a punching equipment for processing new energy vehicle parts, which solves the problems in the prior art such as the difficulty in removing the oil seal seat ring after punching and the risk of operators' hands being pinched.

[0006] To solve the above-mentioned technical problems, this utility model provides a punching device for processing new energy vehicle parts, including an upper die base and a lower die base. A punch is fixed at the center of the bottom surface of the upper die base, and four vertically downward driving blocks are evenly distributed on the outer periphery of the punch. A square frame is provided on the top surface of the lower die base, and a lower clamping plate is fitted and nested inside the square frame. A punching hole coaxial with the punch is opened in the center of the lower clamping plate. Trapezoidal grooves are opened on the four side walls of the lower clamping plate body, and clamping components are slidably fitted in the trapezoidal grooves. The clamping components are connected to a reset component, which penetrates through the side wall of the square frame. The reset component is used to provide the reset force of the clamping component, so that the clamping component can automatically release the oil seal seat ring after punching is completed.

[0007] A further improvement of the present invention is that: an upper clamping plate is provided on the bottom surface of the upper mold base, a punch is provided at the center of the upper clamping plate, and four vertically downward driving blocks are evenly distributed on the upper clamping plate on the outer periphery of the punch.

[0008] A further improvement of the present invention is that the drive block is a cuboid with its top surface fixed to the upper clamping plate and an inclined surface A set on its bottom surface near a corner of the punch. The inclined surface A has an inclination angle of 42° to 48°.

[0009] A further improvement of this utility model is that: a placement platform is provided at the center of the top surface of the lower clamping plate, and the punch holes on the lower clamping plate penetrate upward through the placement platform. The placement platform holds the oil seal base, and a horizontal trapezoidal groove is provided in the center of the perimeter of the lower clamping plate body. A trapezoidal block is adapted to be placed in the trapezoidal groove.

[0010] A further improvement of the present invention is that the clamping assembly includes a trapezoidal block, a slider is provided on the top surface of the trapezoidal block, the length and width of the top surface of the trapezoidal block are equal to the length and width of the slider, an inclined surface B is provided on the corner of the top surface of the slider away from the punch, the inclined surface B is parallel to the inclined surface A, and the vertical height of the slider is greater than the vertical height of the inclined surface A.

[0011] A further improvement of this utility model is that a protrusion is provided in the middle of the side of the slider near the punch, and a replaceable fixing plate is provided on the end face of the protrusion. The fixing plate can be any one of arc shape, V shape, or square shape.

[0012] A further improvement of this utility model is that a baffle is provided on the upper part of the arc surface of the fixing plate away from the protrusion, and a horizontally penetrating settlement hole is provided in the middle of the fixing plate. A bolt is provided in the settlement hole, and the bolt is threadedly connected to the protrusion.

[0013] A further improvement of the present invention is that the reset assembly includes a column that horizontally penetrates the side wall of a square frame, one end of the column is connected to a trapezoidal block, a spring is fitted on the part of the column located outside the square frame, and an integrally formed threaded head is provided at its end. The diameter of the threaded head is smaller than the diameter of the column, a limiting ring is fitted on the threaded head and a nut is screwed to the end.

[0014] A further improvement of the present invention is that the lower mold base includes a top plate, a lower clamping plate is fixed to the top surface of the top plate, the bottom edge of the top plate is fixed to the base plate by two parallel support plates, and a punch penetrates the top plate.

[0015] A further improvement of this utility model is that the upper ends of the spring columns are fixed at the four corners of the bottom surface of the upper mold base, and the lower ends of the spring columns are fixed at the four corners of the top surface of the top plate. The spring columns adopt a nitrogen spring structure to connect the upper mold base and the top plate to achieve buffering.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] 1. This utility model provides a punching device for processing new energy vehicle parts. By setting up a clamping component and a resetting component, after punching, the resetting component can provide a resetting force to the clamping component, causing it to automatically release the oil seal seat ring. This effectively solves the problem of the oil seal seat ring being difficult to remove after punching in traditional punching equipment. Specifically, after the punching process is completed, the upper die seat drives the punch and the drive block to retract upwards. At this time, the drive block and the inclined surface of the slider disengage. The spring in the resetting component, which was originally in a compressed state, acts on the column after the continuous pushing force of the drive block is removed. This causes the column to move the trapezoidal block outwards, and the trapezoidal block in turn drives the slider and the entire clamping component to slide outwards synchronously, thereby automatically releasing the punched oil seal seat ring. This allows it to be easily and quickly removed from the lower clamping plate without the need for manual labor to peel the oil seal seat ring from the positioning groove. This effectively avoids the difficulty in removing the oil seal seat ring after punching in traditional equipment and the risk of pinching injury.

[0018] 2. The punching equipment for processing new energy vehicle parts provided by this utility model has an upper clamping plate on the bottom surface of the upper die base. The driving blocks evenly distributed on its outer periphery cooperate with the trapezoidal groove and clamping components of the lower clamping plate to stably clamp the oil seal seat ring during the punching process, prevent the oil seal seat ring from shifting in the horizontal direction, ensure punching accuracy, and improve the processing quality of the oil seal seat ring.

[0019] 3. The punching equipment for processing new energy vehicle parts provided by this utility model can be flexibly replaced according to the different shapes and sizes of oil seal seats through the design of replaceable fixing plates, which improves the versatility and adaptability of the equipment. The fixing plates of different shapes such as arc, V, and square can better fit the surface of various oil seal seats and enhance the clamping effect. The fixing plates can be easily installed and disassembled through the threaded connection between the bolts and the protrusions, making it easy to replace fixing plates of different shapes or wear as needed, thus reducing the maintenance cost of the equipment.

[0036] The present invention will be further explained below with reference to specific embodiments.

[0037] like Figures 1-11 As shown in the figure, this embodiment provides a punching device for processing new energy vehicle parts, including an upper die base 1 and a lower die base 2. A punch 11 is fixed at the center of the bottom surface of the upper die base 1. Four vertically downward driving blocks 12 are evenly distributed on the outer periphery of the punch 11. A square frame 22 is provided on the top surface of the lower die base 2. A lower clamping plate 23 is fitted and nested inside the square frame 22. A punching hole 21 coaxial with the punch 11 is opened at the center of the lower clamping plate 23. Trapezoidal grooves 24 are opened on the four side walls of the lower clamping plate 23. A clamping assembly 3 is slidably fitted inside the trapezoidal grooves 24. The clamping assembly 3 is connected to a reset assembly 220. The reset assembly 220 penetrates the side wall of the square frame 22. The reset assembly 220 is used to provide a reset force for the clamping assembly 3 so that the clamping assembly 3 can automatically release the oil seal seat ring 29 after punching is completed. Four vertically downward driving blocks 12 are evenly distributed around the outer periphery of the punch 11. During the punching process, as the upper die seat 1 moves downward, the driving blocks 12 cooperate with the corresponding components in the clamping assembly 3 to drive the clamping assembly 3 to move, enabling the clamping assembly 3 to stably clamp the oil seal seat ring 29 during punching. By setting the clamping assembly 3 and the reset assembly 220, after punching, the reset assembly 220 can provide a reset force to the clamping assembly 3, causing it to automatically release the oil seal seat ring 29. This effectively solves the problem that the oil seal seat ring is not easy to remove after punching in traditional punching equipment. There is no need to manually peel the oil seal seat ring 29 from the positioning groove, effectively avoiding the difficulty in removing the oil seal seat ring 29 after punching in traditional equipment and the risk of pinching injury.

[0038] like Figure 1 , Figure 3 As shown, in this embodiment, an upper clamping plate 13 is provided on the bottom surface of the upper mold base 1, and a punch 11 is provided at the center of the upper clamping plate 13. Four vertically downward driving blocks 12 are evenly distributed on the upper clamping plate 13 around the outer periphery of the punch 11. The four driving blocks 12 are symmetrically distributed to achieve radially balanced pressure, eliminate the offset of the oil seal seat ring 29 caused by unilateral clamping, force the center of the oil seal seat ring 29 to coincide with the axis of the punch, and ensure the consistency of the hole position. The driving block 12 is a cuboid in shape, with its top surface fixed to the upper clamping plate 13. An inclined surface A14 is provided on its bottom surface near a corner of the punch 11, and the inclination angle of the inclined surface A14 is 42°~48°. When the punch 11 applies downward punching force to the oil seal seat ring 29, the inclined surface A14 on the bottom surface of the driving block 12 comes into contact with and acts on the inclined surface B33 in the clamping assembly. According to the principle of mechanics, the punching force can be decomposed into a normal force perpendicular to the inclined surface and a tangential force parallel to the inclined surface. The inclination angle of the inclined plane A14 is 42°~48°, which allows for a good balance between the tangential and normal forces. The tangential force can effectively push the clamping assembly to move along the trapezoidal groove 24 towards the punch 21, thereby clamping the oil seal seat ring 29; at the same time, the normal force is not too large, avoiding excessive compression and friction between the clamping assembly and the trapezoidal groove, thus ensuring that the clamping assembly can move smoothly and achieve precise clamping position control.

[0039] like Figure 2 , Figure 4 , Figures 7-9As shown, in this embodiment, a placement platform 28 is provided at the center of the top surface of the lower clamping plate 23, and the punch 21 on the lower clamping plate 23 penetrates upward through the placement platform 28. The placement platform 28 holds the oil seal base 29. A horizontal trapezoidal groove 24 is provided in the middle of the perimeter of the lower clamping plate 23, and a trapezoidal block 31 is adapted to be placed in the trapezoidal groove 24. The trapezoidal groove 24 provides a precise sliding track for the trapezoidal block 31, ensuring stable horizontal movement of the clamping assembly 3, reducing wobbling or offset during sliding, and enhancing the stability and rigidity of the entire clamping system. This enables clamping and releasing of the oil seal seat 29. The clamping assembly 3 includes the trapezoidal block 31, with a slider 32 on its top surface. The length and width of the top surface of the trapezoidal block 31 are equal to the length and width of the slider 32. An inclined surface B33 is provided on the corner of the top surface of the slider 32 away from the punch 11. The inclined surface B33 is parallel to the inclined surface A14, and the vertical height of the slider 32 is greater than the vertical height of the inclined surface A14. After the drive block 12 pushes the clamping assembly 3 to the clamping position, there is still sufficient stroke for the drive block 12 to continue moving downward along the outer side of the slider 32. This ensures that the punch 11 can maintain a downward punching stroke after clamping the oil seal seat 29, allowing the punch 11 to smoothly reach the predetermined punching position of the oil seal seat 29. A protrusion 34 is provided on the middle side of the slider 32 near the punch 11. A replaceable fixing plate 35 is provided on the end face of the protrusion 34. The fixing plate 35 can be any shape, such as arc, V-shape, or square. A baffle 353 is provided on the upper part of the arc surface of the fixing plate 35 away from the protrusion 34. After the punching process is completed, the upper die holder 1 drives the punch 11 to move upward. At this time, the drive block 12 moves upward along the outer side of the slider 32, and the baffle 353 abuts against the top edge of the oil seal bottom ring 29. Through this action, the baffle 353 applies a downward pushing force to the oil seal bottom ring 29, thereby enabling the oil seal bottom ring 29 to smoothly disengage from the punch 11 and complete the stripping process after punching.

[0040] A horizontally penetrating settlement hole 351 is provided in the center of the fixing plate 35, and a bolt 352 is installed in the settlement hole 351, which is threadedly connected to the protrusion 34. The replaceable fixing plate 35 is designed to be arc-shaped, V-shaped, or square, and can be selected and replaced according to the shape of the oil seal seat 29, so as to effectively clamp oil seal seat 29 of different shapes and improve the versatility and flexibility of the equipment. The fixing plate 35 is threadedly connected to the protrusion 34 by the bolt 352, which is convenient for installation and disassembly, and facilitates the replacement of fixing plates of different shapes or wear as needed, ensuring the reliability of the clamping effect.

[0041] like Figure 2 , Figure 6 , Figure 10As shown, in this embodiment, the reset component 220 includes a column 221 that horizontally penetrates the side wall of the square frame 22. The inner end of the column 221 is connected to a trapezoidal block 31. The portion of the column 221 located outside the square frame 22 is fitted with a spring 222, and its outer end is provided with an integrally formed threaded head 223. The diameter of the threaded head 223 is smaller than the diameter of the column 221. The threaded head 223 is fitted with a limiting ring 224 and a nut 225 is screwed to its end. The spring 222 fitted on the column 221 can pull the clamping component 3 back to its initial position by the elastic force of the spring 22 after the clamping component 3 completes the clamping action, achieving rapid reset. This ensures that the clamping component 3 can reliably and automatically reset after punching, achieving rapid release of the oil seal seat 29. This effectively solves the problem that the oil seal seat 29 is not easy to remove after punching in traditional punching equipment. There is no need to manually peel the oil seal seat 29 from the positioning groove, effectively avoiding the difficulty in removing the oil seal seat 29 after punching in traditional equipment and the risk of possible pinching.

[0042] like Figure 5 As shown, in this embodiment, the lower die holder 2 includes a top plate 25, with a lower clamping plate 23 fixed to the top surface of the top plate 25. The bottom edge of the top plate 25 is fixed to the bottom plate 27 via two parallel support plates 26, and a punch 21 penetrates the top plate 25. This structure creates a waste channel in the hollow area between the support plates 26, allowing waste generated during punching to be discharged through the punch 21. The waste falls directly to the area of ​​the bottom plate 27, preventing waste accumulation. This ensures the accuracy and normal operation of the next stamping operation, guaranteeing the continuity and stability of the stamping process.

[0043] like Figure 1 As shown, the upper ends of spring pillars 4 are fixed at the four corners of the bottom surface of the upper mold base 1, and the lower ends of spring pillars 4 are fixed at the four corners of the top surface of the top plate 25. The spring pillars 4 adopt a nitrogen spring structure to connect the upper mold base 1 and the top plate 25 to achieve buffering.

[0044] The working principle of a punching device for processing new energy vehicle parts provided in this embodiment is as follows: When the punching is started, the upper die base 1 moves downward with the punch press, and the punch 11, which is fixed at the center of its bottom surface, moves closer to the oil seal seat ring 29. At this time, the inclined surface A14 of the bottom surface of the driving block 12 on the outer periphery of the punch 11 contacts the inclined surface B33 of the clamping assembly 3. As the upper die base 1 continues to move downward, the driving block 12 pushes the clamping assembly to slide along the trapezoidal groove 24 towards the punching hole 21, so that the fixing plate 35 clamps the oil seal seat ring 29. After the oil seal seat ring 29 is firmly clamped, the driving block 12 continues to move downward along the outer side of the slider 32, and the punch 11 continues to move downward, accurately acting on the predetermined position of the oil seal seat ring 29 to complete the punching. The punching waste is discharged through the punching hole 21 of the lower die base 2. After the punching process is completed, the upper die base 1 drives the punch 11 to move upward. At this time, the drive block 12 moves upward along the outer side of the slider 32, and the baffle 353 abuts against the top edge of the oil seal bottom ring 29. Through this action, the baffle 353 applies a downward pushing force to the oil seal bottom ring 29, thereby enabling the oil seal bottom ring 29 to smoothly disengage from the punch 11. When the drive block 12 moves upward to contact the inclined plane A14 and inclined plane B33 and continues to move upward, the spring column 4 rebounds, driving the upper die seat 1 to move upward and reset. At the same time, the spring 222 on the column 221 pulls back the clamping assembly 3 to the initial position. The operator removes the punched oil seal seat ring 29 from the placement table 28 for subsequent processing. This punching equipment clamps the oil seal seat ring 29 firmly and effectively solves the problem that the oil seal seat ring is not easy to remove after punching in traditional punching equipment. It eliminates the need for manual labor to peel the oil seal seat ring 29 from the positioning groove, avoiding the difficulty in removing the oil seal seat ring 29 after punching in traditional equipment and the risk of pinching.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
