Description

Technical Field

[0001] This application relates to the field of automobile manufacturing, and more particularly to a trimming and shaping mechanism. Background Technology

[0002] Some vehicle charging ports require switching during processing, and the drawn charging port profile cannot be stepped to improve trimming conditions. Furthermore, there are angle requirements between the stamping direction and the trimming line surface during trimming; if the trimming angle is too large, it will generate a large amount of metal chips and cause rapid wear of the cutting edge. When the trimming surface exceeds the angle requirement, front trimming cannot be performed; only side trimming or shaping before trimming is possible. This necessitates two processes to achieve good workpiece processing, making the process cumbersome. Simultaneously, one side of the workpiece will be unprotected during processing, causing it to warp during the pressing process, affecting production quality. Utility Model Content

[0003] To address the problem of difficult processing of vehicle side charging ports, this application provides a trimming and shaping mechanism that facilitates the processing of vehicle side charging ports.

[0004] This application provides a trimming and shaping mechanism for trimming and shaping a workpiece. The trimming and shaping mechanism includes a first mold, a shaping component, and a trimming element. The first mold has an inclined surface and a horizontal surface, which are arranged at an angle. At least a portion of the workpiece is pressed against the inclined surface. The shaping component is configured to move along a first direction to bend the portion of the workpiece pressed against the inclined surface to abut against the horizontal surface. The trimming element is configured to trim the bent portion of the workpiece.

[0005] Understandably, by setting up a first mold with an inclined plane and a horizontal plane, when the trimming angle of the workpiece is too large, the forming component can bend the workpiece to abut against the horizontal plane to reduce the trimming angle, facilitating subsequent trimming. Furthermore, the workpiece is at least partially pressed against the inclined plane, preventing the remaining part of the workpiece from warping up and affecting the workpiece's processing quality when the forming component presses down to shape it. The trimming component can trim the bent area of ​​the shaped workpiece, allowing shaping and trimming to be completed in one process. During trimming, the forming component can continue to hold the workpiece down to act as a pressure point, ensuring the reliability of the trimming process.

[0006] In one embodiment, along a second direction, the trimming member is disposed on one side of the shaping component, the second direction intersects with the first direction, the bent portion of the workpiece is designated as the bent portion, along the second direction, one end of the bent portion extends beyond the horizontal plane, and the trimming member is configured to trim the end of the bent portion that extends beyond the horizontal plane.

[0007] In one embodiment, the trimming member is movable along the first direction to press down one end of the bent portion that extends beyond the horizontal plane.

[0024] like Figures 1 to 3As shown, this application embodiment provides a trimming and shaping mechanism 100 for trimming and shaping a workpiece 200. The trimming and shaping mechanism 100 includes a first mold 1, a shaping component 2, and a trimming part 3. The first mold 1 has an inclined surface 11 and a horizontal surface 12, which are arranged at an angle θ. The workpiece 200 is at least partially pressed against the inclined surface 11.

[0025] For ease of reading, this application introduces the terms first direction Z, second direction X, and third direction Y to describe the embodiments of this application. The first direction Z, second direction X, and third direction Y can be three non-parallel straight lines in space; further, the first direction Z, second direction X, and third direction Y can be three mutually perpendicular directions in a three-dimensional coordinate system (a three-dimensional Cartesian coordinate system). In subsequent embodiments, the first direction Z is described as the Z-axis direction of the three-dimensional coordinate system, the second direction X as the X-axis direction of the three-dimensional coordinate system, and the third direction Y as the Y-axis direction of the three-dimensional coordinate system.

[0026] The shaping component 2 is configured to move along a first direction Z to bend a portion of the workpiece 200 pressed against the inclined surface 11 to abut against the horizontal surface 12. The trimming component 3 is configured to trim the bent portion of the workpiece 200.

[0027] In this embodiment, the workpiece 200 is a vehicle accessory, and after processing, it can be used for subsequent assembly. The first mold 1 is a lower mold, which can be set to correspond to the workpiece 200 so that the workpiece 200 can be placed along the inclined plane 11. The horizontal plane 12 of the first mold 1 is parallel to the plane containing the second direction X and the third direction Y, and the horizontal plane 12 is connected to the end of the inclined plane 11 away from the ground. The inclined plane 11 is a plane that is set at a certain angle θ with the horizontal plane 12. This angle θ is an obtuse angle, and its specific angle can be 165° or other angles that are convenient for processing. When not being processed, most of the workpiece 200 is located on the inclined plane 11 and is pressed down, while a small part is suspended and does not contact the first mold 1 due to the setting of the horizontal plane 12 of the first mold 1. This part of the workpiece 200 can be bent by the shaping component 2 to abut against the horizontal plane 12.

[0028] The shaping assembly 2 may include components such as a pressure plate and a cutting tool for shaping. The shaping assembly 2 can move along the first direction Z to press the workpiece 200 located above the horizontal plane 12 down to abut against the horizontal plane 12, thereby completing the shaping of the workpiece 200. The trimming component 3 may be a cutting tool or other components capable of trimming, without much restriction. After the shaping assembly 2 has completed the shaping, the trimming component 3 continues to move along the first direction Z to trim the bent area of ​​the workpiece 200. At this time, the shaping assembly 2 continues to press on the workpiece 200, thereby playing a pressing role and keeping part of the workpiece 200 abutting against the horizontal plane 12, ensuring the stability of the workpiece 200 during the trimming process.

[0029] Understandably, by setting up a first mold 1 with an inclined surface 11 and a horizontal surface 12, when the trimming angle of the workpiece 200 is too large, the forming component 2 can bend the workpiece 200 to abut against the horizontal surface 12 to reduce the trimming angle of the workpiece 200, facilitating subsequent trimming. Furthermore, at least part of the workpiece 200 is pressed against the inclined surface 11, preventing the remaining part of the workpiece 200 from warping up and affecting the processing quality of the workpiece 200 when the forming component 2 presses down to shape it. The trimming component 3 can trim the bent portion of the shaped workpiece 200, allowing shaping and trimming to be completed in one process. During trimming by the trimming component 3, the forming component 2 can continue to press down on the workpiece 200 to act as a pressure point, ensuring the reliability of the trimming process.

[0030] In one embodiment, along the second direction X, the trimming member 3 is disposed on one side of the shaping component 2, the bent portion of the workpiece 200 is designated as the bent portion 201, one end of the bent portion 201 extends beyond the horizontal plane 12 along the second direction X, and the trimming member 3 is configured to trim the end of the bent portion 201 that extends beyond the horizontal plane 12.

[0031] In this embodiment, the portion located above the horizontal plane 12 is the bent portion 201. During the shaping process of the workpiece 200, this portion is bent and held against the horizontal plane 12. Since the workpiece 200 was originally placed at an angle to the horizontal plane 12, during the process of bending the workpiece 200 portion to the horizontal plane 12, one end of the bent portion 201 will extend beyond the horizontal plane 12 along the second direction X. Along the second direction X, a trimming member 3 provided on one side of the shaping assembly 2 can trim the portion of the bent portion 201 that extends beyond the horizontal plane 12.

[0032] It is understandable that the trimming part 3 is set on one side of the forming assembly 2 along the second direction X so that it can trim the workpiece 200 after forming, so that forming and trimming can be completed in one process, which facilitates the processing of the workpiece 200.

[0033] In one embodiment, the trimming member 3 can move along a first direction Z to press down one end of the bent portion 201 that extends beyond the horizontal plane 12.

[0034] Understandably, the trimming part 3 can be driven to move along the first direction Z, thereby pressing down and trimming the end of the bent portion 201 that extends beyond the horizontal plane 12.

[0035] In one embodiment, the trimming and shaping mechanism 100 further includes a drive component 4 configured to drive the shaping component 2 and the trimming element 3 to move along a first direction Z.

[0036] In this embodiment, the trimming and shaping mechanism 100 further includes a second mold 9, which is an upper mold. The driving component 4 is connected to the second mold 9, and the shaping component 2 and the trimming part 3 are connected to the driving component 4 and driven by the driving component 4 to move along the first direction Z. The driving component 4 drives the shaping component 2 and the trimming part 3 to move along the first direction Z with the same stroke.

[0037] It is understandable that by setting the drive component 4, the shaping component 2 and the trimming component 3 can move along the first direction Z, thereby enabling shaping and trimming processes.

[0038] Further integration Figure 4 and Figure 5 As shown, in one embodiment, the trimming and shaping mechanism 100 further includes a first elastic member 5. Along the first direction Z, the first elastic member 5 is disposed between the driving component 4 and the shaping component 2. One end of the first elastic member 5 is connected to the driving component 4, and the other end is elastically connected to the shaping component 2.

[0039] In this embodiment, the first elastic element 5 can be a nitrogen spring. When the workpiece 200 is not being shaped, the drive assembly 4 drives the shaping assembly 2 to move along the first direction Z. At this time, the first elastic element 5 mainly serves a connecting function and does not apply additional force to the shaping assembly 2. When the shaping assembly 2 bends part of the workpiece 200 to abut against the horizontal surface 12, the drive assembly 4 continues to move along the first direction Z so that the trimming element 3 connected to the drive assembly 4 can be trimmed. At this time, since the shaping assembly 2 abuts against the workpiece 200 and the workpiece 200 abuts against the horizontal surface 12, the first elastic element 5 is compressed when the drive assembly 4 continues to move along the first direction Z, and an elastic force is applied to the shaping assembly 2 so that the shaping assembly 2 presses the workpiece 200 more tightly.

[0040] Understandably, the first elastic element 5 is provided to provide uniform elastic force, ensuring that the workpiece 200 is subjected to consistent force during processing, avoiding deformation or displacement, and protecting the equipment and mold, thus extending their service life. The first elastic element 5 also allows the trimming part 3 to continue moving along the first direction Z during trimming after forming. Simultaneously, the first elastic element 5 is compressed to generate elastic force acting on the workpiece 200, allowing the forming assembly 2 to better press the workpiece 200 onto the first mold 1, thus enabling the forming assembly 2 to function as a material clamping device.

[0041] In one embodiment, the trimming and shaping mechanism 100 further includes a pressing member 6, which can press the workpiece 200 onto the inclined surface 11.

[0042] Understandably, the pressure piece 6 presses the workpiece 200 onto the inclined surface 11 to ensure that the workpiece 200 will not lift up during subsequent shaping and trimming processes, thus ensuring that the workpiece 200 is well processed.

[0043] In one embodiment, the trimming and shaping mechanism 100 further includes a second elastic member 7. Along the first direction Z, the second elastic member 7 is disposed between the shaping component 2 and the pressing component 6. One end of the second elastic member 7 is elastically connected to the pressing component 6, and the other end is elastically connected to the shaping component 2.

[0044] In this embodiment, the second elastic element 7 can be a nitrogen spring. The second elastic element 7 is provided to make the return stroke of the shaping assembly 2 more stable and reliable after processing.

[0045] In one embodiment, the trimming and shaping mechanism 100 further includes a first guide member 8, which is disposed between the shaping component 2 and the pressing component 6 along the second direction X, and guides the movement of the shaping component 2 along the first direction Z.

[0046] In this embodiment, the first guide member 8 may be a guide plate, which can be connected to the shaping component 2. During operation, the first guide member 8 can be located between the shaping component 2 and the pressing component 6 along the second direction X. The first guide member 8 can extend along the first direction Z to guide the movement of the shaping component 2 along the first direction Z.

[0047] It is understandable that by setting the first guide member 8, the shaping component 2 can be guided by the first guide member 8 during the process of being driven to move along the first direction Z, so as to ensure that the shaping process of the shaping component 2 is more reliable and the processing quality is higher.

[0048] Further integration Figure 6 As shown, in one embodiment, the drive assembly 4 includes a base 41, a drive member 42, and a mounting member 43. The drive member 42 and the mounting member 43 are connected to the base 41. The drive member 42 is configured to drive the mounting member 43 to move along a first direction Z. The trimming member 3 and the shaping assembly 2 are connected to the mounting member 43.

[0049] In this embodiment, the driving component 42 can be a cylinder, and the mounting component 43 can be a mounting base that allows the trimming component 3 and the shaping component 2 to be connected to the mounting component 43; no further restrictions are imposed here. The driving component 42 can drive the mounting component 43 to move relative to the base 41 along the first direction Z, that is, the mounting component 43 can extend and retract relative to the base 41 along the first direction Z, thereby driving the trimming component 3 and the shaping component 2 connected to the mounting component 43 to move along the first direction Z.

[0050] Understandably, the setting of the drive component 4 allows the working state of the trimming and shaping mechanism 100 to be switched. When the workpiece 200 needs to be trimmed and shaped, the drive component 42 drives the mounting component 43 to move along the first direction Z. When the workpiece 200 does not need to be processed, the drive component 42 can be turned off and the mounting component 43 is not driven.

[0051] In one embodiment, the drive assembly 4 further includes a guide assembly 44 connected to the mounting member 43, the guide assembly 44 guiding the movement of the mounting member 43 along the first direction Z.

[0052] In this embodiment, the guide assembly 44 includes a second guide member 441 and a third guide member 442. The second guide member 441 may be a guide plate, and the third guide member 442 may be a guide post. The guide assembly 44 can guide the movement of the mounting member 43 along the first direction Z.

[0053] Understandably, the guidance of the guide component 44 makes the movement of the mounting part 43 in the first direction Z more accurate and reliable, thereby making the machining process more precise and the machining quality better.

[0054] The specific embodiments of this application have been described above with reference to the accompanying drawings. However, those skilled in the art will understand that various changes and substitutions can be made to the specific embodiments of this application without departing from the spirit and scope of this application. All such changes and substitutions fall within the scope defined by this application.
