Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a wheel rim punching, trimming and punching mold. Background Art

[0002] The structural parts of automobiles are generally made of steel plates through processes such as blanking, bending, trimming, and punching of mounting holes. The complexity of the process results in a large number of process equipment and molds required in the production process of automobile structural parts. The amount of molds used reflects the production capacity and level of the manufacturer on the one hand, and also reflects the cost and quality of production.

[0003] Existing wheel rim punching, trimming and punching dies generally only complete core processes such as punching, trimming and punching, and do not cover the process of shaping the wheel rim into a cone. After completing the above basic processing, manufacturers still need to transfer the workpiece to the shaping process to achieve the final tapered design requirements of the product, which increases production time. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a wheel rim punching, trimming and breaking die to solve the technical problem that the existing die does not cover the process of shaping the wheel rim into a cone.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wheel rim punching, trimming and cutting die, comprising a base, to which a conical die is fixedly connected, a first hydraulic rod is arranged inside the conical die, a lifting platform is fixedly connected to the top of the first hydraulic rod, and a punching hole is opened on the lifting platform.

[0006] By adopting the above technical solution, a stable shaping foundation is provided for the shaping of the rim through the conical mold fixedly connected to the base. The design of the conical mold enables the rim to be accurately shaped into the required conical structure, meeting the requirements of product design.

[0007] Furthermore, connecting plates are fixedly connected on both sides of the base, and a cross bar is slidably connected to the top of the connecting plate. There are multiple cross bars, and one end of each of the cross bars is fixedly connected to a force-bearing plate. A second hydraulic rod is fixedly connected to one side of the connecting plate, and one end of the second hydraulic rod is fixedly connected to the force-bearing plate.

[0008] By adopting the above technical solution, the connecting plates fixedly connected on both sides of the base and the cross bars slidably connected thereto provide additional stability and support for the mold, so that the mold can remain stable when subjected to greater pressure, thereby ensuring the reliability of processing accuracy and product quality.

[0009] Furthermore, one end of the crossbar is fixedly connected to a semi-circular platform, and the top of the semi-circular platform is fixedly connected to a supporting surface via a vertical rod.

[0010] By adopting the above technical solution, the semi-circular platform fixedly connected to one end of the cross bar provides a stable platform for the placement and processing of the wheel rim. As a base, the semi-circular platform can provide a stable installation platform for subsequent components.

[0011] Furthermore, a trimming knife is slidably connected inside the supporting surface, and a third hydraulic rod is arranged between the trimming knife and the semi-circular platform.

[0012] By adopting the above technical solution, the trimming knife slidably connected inside the supporting surface can conveniently perform trimming operations on the wheel rim. The trimming knife can slide flexibly inside the supporting surface to ensure the accuracy and flatness of trimming, thereby improving the product quality and aesthetics.

[0013] Furthermore, an internal pressure column is arranged above the lifting platform, and a blanking knife is fixedly connected to the bottom of the internal pressure column.

[0014] By adopting the above technical solution, the internal pressure column arranged above the lifting platform provides a stable pressure source for the blanking operation. The internal pressure column can apply uniform and powerful pressure downward to ensure the stability and accuracy during the blanking process.

[0015] Furthermore, an external pressure ring is sleeved outside the internal pressure column, and a trimming groove is formed at the bottom of the external pressure ring.

[0016] By adopting the above technical solution, the external pressure ring sleeved outside the internal pressure column plays an auxiliary shaping and stabilizing role during the blanking process. The external pressure ring can ensure that the material is subjected to uniform pressure during blanking, preventing the material from shifting or deforming during the blanking process, thereby improving the accuracy and quality of the product.

[0017] Furthermore, there are two sets of the connecting plate, the semi-circular platform and the supporting surface, and the two sets of the connecting plate, the semi-circular platform and the supporting surface are arranged in a mirror image structure.

[0018] By adopting the above technical solution, the mirror image structure enables sliding to both sides when subsequent operations are required, achieving the function of making way for the conical mold at the bottom while also providing sufficient support.

[0019] Furthermore, an ear platform is fixedly connected to one side of the supporting surface, and a positioning column is fixedly connected to the top of the ear platform.

[0020] By adopting the above technical solution, the ear platform fixedly connected to one side of the supporting surface provides a convenient platform for positioning operations. The design of the ear platform enables the positioning column to be stably installed thereon, thereby ensuring the accuracy of positioning.

[0021] In summary, the present utility model mainly has the following beneficial effects:

[0022] 1. The utility model realizes the integrated operation of multiple process steps such as punching, trimming, and shaping by setting a conical mold and an internal pressure column. By setting components such as the conical mold and the internal pressure column, the production process is simplified, the production efficiency is improved, and the production cost is reduced. The synergistic effect of each component ensures the accuracy and consistency of processing. By performing multiple processes in the same step, the position accuracy is improved, and thus the production tolerance is reduced.

[0032] The following will describe the embodiments according to the overall structure of the present utility model.

[0033] Embodiment 1:

[0034] A wheel rim punching, trimming and blanking die, as Figures 1-4 shown, includes a base 1, a conical die 2 is fixedly connected to the base 1, a first hydraulic rod 3 is arranged inside the conical die 2, the top of the first hydraulic rod 3 is fixedly connected to a lifting table 4, a punching through-hole 5 is provided on the lifting table 4. The conical die 2 fixedly connected to the base 1 provides a stable shaping basis for the shaping of the wheel rim. The design of the conical die 2 enables the wheel rim to be accurately shaped into the required conical structure, meeting the requirements of product design. At the same time, the coordinated use of the first hydraulic rod 3 and the lifting table 4 enables the die to perform efficient lifting movements, and the punching through-hole 5 provided on the lifting table 4 facilitates the timely discharge of waste during the punching process, ensuring the smooth progress of the punching process.

[0035] Refer to Figure 1 、 Figure 2 and Figure 3, connecting plates 6 are fixedly connected to both sides of the base 1, and a cross bar 7 is slidably connected to the top of the connecting plate 6. There are multiple cross bars 7, and one end of the multiple cross bars 7 is fixedly connected to a force-bearing plate 8. A second hydraulic rod 9 is fixedly connected to one side of the connecting plate 6, and one end of the second hydraulic rod 9 is fixedly connected to the force-bearing plate 8. The connecting plates 6 fixedly connected on both sides of the base 1 and the cross bars 7 slidably connected thereto provide additional stability and supporting force for the mold, so that the mold can remain stable when subjected to greater pressure, thereby ensuring the reliability of processing accuracy and product quality. At the same time, the force-bearing plates 8 fixed at one end of the multiple cross bars 7 are connected to the second hydraulic rod 9. Through the telescopic function of the second hydraulic rod 9, the movement of the force-bearing plate 8 and the cross bar 7 can be flexibly controlled, which facilitates the use of the mold and enables the mold to be quickly deformed according to different links during use.

[0036] See also Figure 1 , Figure 2 and Figure 3 One end of the cross bar 7 is fixedly connected to a semi-annular platform 10, and the top of the semi-annular platform 10 is fixedly connected to a supporting surface 12 through a vertical rod 11. The semi-annular platform 10 fixedly connected to one end of the cross bar 7 provides a stable platform for the placement and processing of the wheel rim. The semi-annular platform 10 serves as a base and can provide a stable installation platform for subsequent components. At the same time, the supporting surface 12 can evenly support the wheel rim to prevent it from deformation or damage during the processing process, thereby ensuring product quality and reducing production losses.

[0037] See also Figure 1 and Figure 3 A trimming knife 13 is slidably connected inside the support surface 12, and a third hydraulic rod 20 is arranged between the trimming knife 13 and the semi-annular platform 10. The trimming knife 13 slidably connected inside the support surface 12 can conveniently perform trimming operations on the rim. The trimming knife 13 can flexibly slide inside the support surface 12 to ensure the accuracy and flatness of the trimming, thereby improving the product quality and aesthetics. At the same time, the third hydraulic rod 20 arranged between the trimming knife 13 and the semi-annular platform 10 provides power for the trimming operation. By controlling the extension and retraction of the third hydraulic rod 20, the position and trimming depth of the trimming knife 13 can be accurately controlled, making the trimming process more automated and accurate, thereby improving production efficiency and product qualification rate.

[0038] See also Figure 1 , Figure 2 and Figure 3, above the lifting table 4, an internal pressure column 14 is provided. The bottom of the internal pressure column 14 is fixedly connected with a blanking knife 15. The internal pressure column 14 provided above the lifting table 4 provides a stable pressure source for the blanking operation. The internal pressure column 14 can apply a uniform and powerful pressure downward to ensure the stability and accuracy during the blanking process. At the same time, the blanking knife 15 fixedly connected to the bottom of the internal pressure column 14 can accurately perform the blanking operation. The sharpness and hardness of the blanking knife 15 ensure that the material can be quickly and accurately cut during the blanking process, thereby improving production efficiency and product quality.

[0039] Refer to Figure 1 , Figure 2 and Figure 3 , an external pressure ring 16 is sleeved outside the internal pressure column 14. A trimming groove 17 is opened at the bottom of the external pressure ring 16. The external pressure ring 16 sleeved outside the internal pressure column 14 plays an auxiliary shaping and stabilizing role during the blanking process. The external pressure ring 16 can ensure that the material is subjected to uniform pressure during blanking, preventing the material from shifting or deforming during the blanking process, thereby improving the accuracy and quality of the product. At the same time, the trimming groove 17 opened at the bottom of the external pressure ring 16 cooperates with the trimming knife 13, enabling the trimming operation to be carried out simultaneously during blanking, so that the two steps of blanking and trimming can be carried out simultaneously. The trimming groove 17 ensures the accuracy of trimming and further improves the product quality.

[0040] Refer to Figure 1 , Figure 2 and Figure 3 , there are two sets of connecting plates 6, semi-circular platforms 10 and supporting surfaces 12. The two sets of connecting plates 6, semi-circular platforms 10 and supporting surfaces 12 are arranged in a mirror image structure. The arrangement of the mirror image structure enables sliding in both directions when subsequent operations are required, achieving the function of making way for the conical mold 2 at the bottom while being able to provide sufficient support. At the same time, by setting the connecting plates 6, semi-circular platforms 10 and supporting surfaces 12 into two sets and arranging them in a mirror image structure, the stability and balance of the mold are improved. The two sets of structures can be evenly distributed on both sides of the base 1, effectively dispersing the pressure and impact force generated during the processing and preventing the mold from tilting or shaking.

[0041] The implementation principle of the present utility model is as follows: First, when punching and shaping are required, first place the metal plate on the supporting surface 12 and the lifting table 4, and then start the internal pressure column 14 and the external pressure ring 16, so that the metal plate can be preliminarily shaped. At the same time, the blanking knife 15 punches out the round hole, and the punched material falls out from the blanking through-hole 5. After that, the third hydraulic rod 20 is started to push the trimming knife 13 to cooperate with the trimming groove 17 on the external pressure ring 16 to complete the trimming operation;

[0042] After that, the second hydraulic rod 9 is activated. The second hydraulic rod 9 pushes the force-bearing plate 8 to move to one side, and then drives the semi-ring platform 10 to move through the cross bar 7, enabling the support surface 12 to slide to both sides and make way. After that, the first hydraulic rod 3 and the inner pressure column 14 are activated, so that the metal plate can be clamped and pushed downward, enabling it to be shaped by the conical mold 2 to complete the specified cone shape.

[0043] Embodiment 2:

[0044] Refer to Figure 4 , on one side of the support surface 12, there is a fixed connection with an ear platform 18. On the top of the ear platform 18, there is a fixed connection with a positioning column 19. The ear platform 18 fixedly connected to one side of the support surface 12 provides a convenient platform for positioning operations. The design of the ear platform 18 enables the positioning column 19 to be stably installed on it, thus ensuring the accuracy of positioning. At the same time, the positioning column 19 fixedly connected to the top of the ear platform 18 plays the role of positioning the rim. The positioning column 19 can hold against the rim to ensure the accurate position of the rim during the processing, thereby improving the processing accuracy and consistency.

[0045] The implementation principle of the present utility model is as follows: First, when it is necessary to place the metal plate, by using the positioning column 19 on the ear platform 18, it is convenient to position the metal plate and improve the feeding efficiency.
