Description

Technical Field

[0001] The utility model relates to the technical field of automobile trunk covers, in particular to a multi-punching mechanism for a trunk cover. Background Art

[0002] The trunk lid is one of the most important parts in the automobile manufacturing process, and its design and manufacturing quality directly affect the appearance and performance of the car. In order to ensure the strength and installation accuracy of the trunk lid, multiple punching operations need to be performed on its surface for subsequent installation and fixation. Traditional punching equipment usually uses a single-specification punch, which is cumbersome and inefficient to operate, and cannot meet the needs of modern automobile manufacturing for efficient and high-precision processing. Therefore, developing a punching mechanism that can adapt to multiple punching requirements is of great significance to improving automobile manufacturing efficiency and product quality.

[0003] The existing trunk lid punching equipment has some obvious shortcomings in actual use. First, traditional punching equipment can usually only perform punching operations of a single specification and cannot meet the needs of multiple punchings, resulting in the need to frequently replace punches and molds during the production process, increasing the complexity of the operation and time cost. Secondly, during the punching process of the existing equipment, the pressure plate and the mold core are not tightly matched, which can easily lead to low punching accuracy and affect the assembly quality of the trunk lid. In addition, during the operation of traditional punching equipment, there is a lack of effective safety protection measures, which is prone to safety accidents such as the pressure plate falling off, threatening the safety of the staff. The existing design is also not convenient enough in terms of punch fixing and disassembly, which increases the difficulty of maintenance and work intensity. Therefore, we provide a variety of punching mechanisms for trunk lids. Utility Model Content

[0027] Example 2

[0028] like Figure 1-4 As shown, a bottom plate 12 is provided at one end of the lower die 8 away from the punching die core 7, an expansion plate 13 is provided on the outer surface of the bottom plate 12, a screw 14 is provided on the expansion plate 13, a second spring 15 is provided on the outer surface of the screw 14, a gasket 16 is provided at one end of the second spring 15, a connector 18 is provided on the bottom plate 12, an adjustment frame 17 is provided on the outer surface of the connector 18, one end of the adjustment frame 17 is fixedly connected to the outer surface of the lower die 8, the outer surface of the connector 18 is limited in the adjustment frame 17 for rotation adjustment, one end of the connector 18 is fixedly connected to the bottom plate 12, one end of the expansion plate 13 is fixedly connected to the outer surface of the bottom plate 12, the screw 14 is fixed by threaded rotation through the expansion plate 13, both ends of the second spring 15 are respectively fixedly connected to the gasket 16 and the screw 14, and the end of the gasket 16 away from the second spring 15 is in contact with the expansion plate 13.

[0029] In this embodiment, in order to facilitate the installation of the lower mold 8, an adjustment frame 17 is provided on the outer surface of the lower mold 8, and a connector 18 is provided in the adjustment frame 17. The staff can fix it on the base plate 12 by the connector 18, and an expansion plate 13 is provided on the outer surface of the base plate 12. The staff can fix the screw 14 through the expansion plate 13 by threaded rotation, and the screw 14 is provided with a second spring 15 and a gasket 16 to protect the screw 14, thereby further improving its practicality in actual use.

[0030] Working principle:

[0031] like Figure 1-4As shown, when the staff uses the punching mechanism of the trunk lid to punch holes, they can lock the upper die base 1 to the slider of the hydraulic press, hang the pressure plate 5 on the upper die base 1 through the travel bolt 3, and fix the punches 4 on the upper die base 1 and hide them in the pressure plate 5. When the slider of the hydraulic press slides down, the pressure plate 5 first contacts the mold core, and the mold core is locked to the lower die base. When the pressure plate 5 is subjected to pressure, the first spring 2 is compressed, and then the punches 4 emerge from the pressure plate 5 and cut into the mold core to complete the punching action. The safety side pin 6 ensures that the pressure plate 5 will not fall off.

[0032] The various punches 4 are composed of a punch cutting edge 9, a punch splitting seat 10, and a punch fixing seat 11. The punch cutting edge 9 has two pin holes and a countersunk hole, corresponding to the two pin holes and a threaded hole on the punch splitting seat 10. The pin holes are used for positioning, and the threaded holes are used to fix the punch cutting edge 9. The various punches 4 are fastened to the punch fixing seat 11 by side locking screws and fixed to the upper die seat 1 by screws. This design is convenient for the staff to perform punching operations.

[0033] In order to facilitate installation and adjustment, an adjustment frame 17 is provided on the outer surface of the lower mold 8, and a connector 18 is provided in the adjustment frame 17, and the staff can fix the connector 18 on the bottom plate 12. An expansion plate 13 is provided on the outer surface of the bottom plate 12, and the staff can fix the screw 14 by rotating it to pass through the expansion plate 13. The screw 14 is provided with a second spring 15 and a gasket 16 for protecting the screw 14.

[0034] This design not only improves the working efficiency of the punching mechanism, but also improves the convenience of installation and adjustment. The travel bolt 3 and the safety side pin 6 ensure the stability and safety of the equipment during operation. The detachable design of multiple punches 4 makes replacement and maintenance more convenient, effectively extending the service life of the equipment.

[0035] In the specific operation, the staff installs the upper die base 1 on the slider of the hydraulic press, and hangs the pressure plate 5 on the upper die base 1. The hydraulic press is started, and when the slider slides down, the pressure plate 5 first contacts the die core, compresses the first spring 2, and then multiple punches 4 emerge from the pressure plate 5 to complete the punching. During this process, the safety side pin 6 prevents the pressure plate 5 from falling off, ensuring safe operation. The setting of the adjustment frame 17 and the connector 18 makes the installation and adjustment of the lower die 8 easier.

[0036] In summary, the various punching mechanisms of the trunk cover not only improve the punching efficiency but also enhance the stability and safety of the equipment through reasonable design and operation. Whether in industrial production or other application scenarios, the equipment can provide efficient and stable punching solutions to meet the needs of different users.
