Figure 1 , Figure 2 , Figure 3 and Figure 4The illustrated embodiment shows a trimming and punching die for processing automobile sunroofs, comprising a lower die body 1, an upper die body 2 and a pressing core 3. The upper die body 2 is arranged above the lower die body 1, and a lower die insert 105 is installed on the lower die body 1, and an upper die insert 210 is installed on the upper die body 2. The position of the upper die insert 210 corresponds to the position of the lower die insert 105, forming a precise processing contour to ensure the accuracy of trimming and punching.

[0041] The pressing core 3 in the present invention is installed between the lower die body 1 and the upper die body 2, and is used to apply pressure to the workpiece during the stamping process to ensure that the workpiece remains stable during processing and prevents deformation; the left and right sides of the lower die insert 105 are respectively provided with a die sleeve 104, and the die sleeve 104 and the lower die body 1 are fixedly connected to each other. The die sleeve 104 is used to guide and support the skylight frame to ensure the position accuracy during the processing process.

[0042] In the present invention, a non-standard punch 2031, a round punch 2061, an oblong punch 2081 and a plurality of springs 202 are fixedly connected to the upper die body 2. The non-standard punch 2031, the oblong punch 2081 and the round punch 2061 are used for forward punching. An oblique wedge 204 is respectively provided on the left and right sides of the upper die insert 210. The oblique wedge 204 and the upper die body 2 are slidably connected to each other. A square punch 2051 is fixedly connected to the oblique wedge 204. The square punch 2051 is used for side punching of the workpiece. The direction of movement is converted by the inclined plane principle, so that the square punch 2051 can perform side punching operations. The square punch 2051 realizes side punching with the help of the oblique wedge 204, thereby meeting the processing requirements of different parts of the skylight frame.

[0043] In the present invention, a plurality of guide columns 101 are fixedly connected to the lower die body 1, and a plurality of guide sleeves 201 are provided on the upper die body 2. The positions of the guide columns 101 and the guide sleeves 201 correspond to each other, which can ensure that the upper and lower die bodies 1 are accurately aligned during stamping and reduce die wear.

[0047] The utility model has lifting rods A107 fixedly connected to the left and right sides of the lower mold body 1, and lifting rods B209 fixedly connected to the left and right sides of the upper mold body 2. The setting of lifting rods A107 and lifting rods B209 makes the mold more convenient during loading and unloading, and reduces the risk of manual handling.

[0048] The present invention has a guide frame 106 fixedly connected to the lower mold body 1, which ensures the correct position of the skylight frame during the processing and reduces the debugging time. The present invention has a plurality of side pins 207 fixedly connected to the upper mold body 2. The addition of the side pins 207 further enhances the stability of the upper mold body 2 and facilitates the daily maintenance and adjustment of the upper mold body 2.

[0049] The above components work together to achieve a high degree of integration, efficiency and stability of the automobile sunroof trimming and punching die, significantly improving processing quality and production efficiency.

[0050] Working principle process:

[0051] 1. Place the skylight frame to be processed on the lower die body 1 and use the die sleeve 104 for preliminary positioning. The shape of the die sleeve 104 matches the edge of the skylight frame, providing basic positioning support to ensure the position accuracy of the workpiece before stamping.

[0052] 2. When the upper die body 2 begins to descend, the pressing core 3 also descends, and the guide pin 202 of the spring further accurately positions the outer frame of the skylight. At the same time, the pressing core 3 applies pressure to the workpiece to ensure that the workpiece remains stable during the entire processing process to prevent any possible deformation or deviation.

[0053] 3. The upper die body 2 continues to descend, with the non-standard punch 2031, oblong punch 2081, and round punch 2061 aligned with predetermined positions on the workpiece to perform forward punching and trimming operations. As the upper die body 2 descends, the inclined wedge 204 is squeezed and slides along a predetermined track, driving the attached square punch 2051 to move laterally, punching different parts of the skylight frame. The inclined surface of the inclined wedge 204 converts vertical motion into horizontal motion, enabling lateral punching.

[0054] Throughout the stamping process, guide posts 101 and guide sleeves 201 ensure precise alignment between the upper and lower die bodies 2 and 1, reducing unnecessary friction and wear between the dies. Furthermore, polyurethane shock-absorbing posts 102 effectively absorb impact forces during the stamping process, protecting the die from vibration damage and extending its life.

[0055] After stamping is complete, waste material automatically slides down via waste slides A103 and B108, facilitating collection and removal. This simplifies the subsequent cleanup process and improves production efficiency. After the stamping process is complete, the upper die body 2 returns to its initial position under the rebound force of spring 202, and the press core 3 rises accordingly, releasing the workpiece. At this point, the finished skylight frame can be removed from the lower die body 1, ready for the next step.

[0056] After completing the processing of one workpiece, repeat the above steps to process the next workpiece until the predetermined production quantity is completed.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
