Description

Technical Field

[0001] This utility model relates to the field of automotive leather punching technology, and more specifically, to a structure for punching holes in the leather of a car driver's side airbag door cover. Background Technology

[0002] In existing technology, a car driver's side airbag consists of components such as a door hood assembly, airbag, leather flap, generator, and sound button. The door hood assembly consists of a door hood shell, leather flap, and emblem.

[0003] In existing technology, the manufacturing method of the door cover assembly involves manually applying adhesive to a leather sheet, attaching it to the door cover surface, and allowing it to dry completely. Since the door cover shell has pre-drilled holes for the logo during injection molding, the mounting holes for the logo need to be manually cut out with a blade before the next step of logo installation can proceed.

[0004] In existing technologies, the logo mounting holes on leather patches require manual cutting with a blade. This process is not only inconvenient but also lacks automation, requiring employees to invest significant time and effort. Furthermore, the instability of factors such as operating force and blade angle during manual cutting leads to poor cutting results and may even damage the product. This undoubtedly increases the uncertainty of product quality, impacting both production efficiency and product quality.

[0005] Therefore, this application proposes a structure for punching holes in the leather panel of the driver's side airbag door cover of an automobile to solve the aforementioned problems. Utility Model Content

[0006] To address the aforementioned issues, this application provides a structure for punching holes in the leather panel of the driver's side airbag door cover of an automobile.

[0007] This application provides a technical solution for a perforated structure for a driver's side airbag door cover panel of an automobile:

[0008] A structure for punching holes in the leather panel of a car driver's side airbag door cover includes:

[0009] A base plate, on which fixed guide posts are arranged in a quadrilateral pattern, a cylinder fixing plate is provided on the top of the fixed guide posts, a servo cylinder is provided on the cylinder fixing plate, and the piston of the servo cylinder passes through the cylinder fixing plate.

[0010] The base plate is also symmetrically provided with sliding columns, and an upper mold fixing plate is slidably connected to the sliding columns. The piston of the electric cylinder is connected to the top flange of the upper mold fixing plate. An upper mold body is provided at the bottom of the upper mold fixing plate, and the upper mold body has a hollow structure inside.

[0011] The base plate is also provided with a lower mold fixing plate. A floating plate is movably connected to the lower mold fixing plate by a limiting bolt. A spring is sleeved on the limiting bolt. The top and bottom of the spring are respectively attached to the bottom of the floating plate and the top of the lower mold fixing plate.

[0012] The floating plate is provided with a lower mold body, and a punch is movably disposed in the lower mold body. The upper mold body is provided with a punch hole corresponding to the punch. When working, the punch is inserted into the interior of the upper mold body through the punch hole. A pad is provided at the bottom of the punch on the lower mold fixing plate.

[0013] Furthermore, a vacuum generator is connected to the hollow portion of the upper mold body.

[0014] Through the above technical solution, the vacuum generator can adsorb the blanking waste carried by the punch into the upper die body, so as to avoid the waste from clogging the punch and affecting the operation of the equipment.

[0015] Furthermore, the upper mold fixing plate and the lower mold fixing plate are provided with corresponding limiting posts.

[0016] Through the above technical solutions, the design of the limiting post ensures rapid alignment and precise installation during mold changes, greatly reducing equipment adjustment time and improving production efficiency; it also improves the consistency of mold alignment, ensuring the punching quality of each batch of products and guaranteeing the stability of production quality.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] (1) The entire punching process is driven by a servo cylinder, which simplifies the operation process and reduces the complexity of operation; the design of fixed punch and floating plate ensures that the product skin can be accurately cut into the predetermined shape.

[0026] Example:

[0027] The following is in conjunction with the appendix Figure 1 -3 provides further detailed description of this application.

[0028] This application discloses a structure for punching holes in the leather panel of a car driver's side airbag door cover, including:

[0029] The base plate 1 has fixed guide posts 2 arranged in a quadrilateral pattern on the base plate 1. A cylinder fixing plate 3 is set on the top of the fixed guide posts 2. A servo cylinder 4 is set on the cylinder fixing plate 3. The piston of the servo cylinder 4 passes through the cylinder fixing plate 3.

[0030] The base plate 1 is also symmetrically provided with sliding columns 5, and the upper mold fixing plate 6 is slidably connected to the sliding columns 5. The piston of the electric cylinder is connected to the top flange of the upper mold fixing plate 6. The bottom of the upper mold fixing plate 6 is provided with the upper mold body 7, and the upper mold body 7 has a hollow structure inside.

[0031] A lower mold fixing plate 8 is also provided on the base plate 1. A floating plate 9 is movably connected to the lower mold fixing plate 8 through a limit bolt. A spring 10 is sleeved on the limit bolt. The top and bottom of the spring 10 are respectively attached to the bottom of the floating plate 9 and the top of the lower mold fixing plate 8.

[0032] A lower mold body 11 is provided on the floating plate 9. A punch 12 is movably provided inside the lower mold body 11. The upper mold body 7 is provided with a punch hole corresponding to the punch 12. When working, the punch 12 is inserted into the interior of the upper mold body 7 through the punch hole. A pad block 13 is provided on the bottom of the punch 12 on the lower mold fixing plate 8.

[0033] See Figure 1 and Figure 2 The hollow part of the upper die body 7 is connected to a vacuum generator; the vacuum generator can absorb the punching waste carried by the punch 12 into the upper die body 7, so as to avoid the waste from clogging the punch and affecting the operation of the equipment.

[0034] See Figure 1 and Figure 2 The upper mold fixing plate 6 and the lower mold fixing plate 8 are equipped with corresponding limiting posts 14. The design of the limiting posts 14 ensures quick alignment and accurate installation when changing molds, greatly reducing equipment adjustment time and improving production efficiency. It also improves the consistency of mold alignment, ensures the punching quality of each batch of products, and guarantees the stability of production quality.

[0035] The implementation principle of the perforated structure of the door cover panel for the driver's side airbag in this application is as follows:

[0036] The mechanism uses a servo cylinder 4 as its power source and is connected to the upper mold fixing plate 6 via a flange. The workpiece is placed on the lower mold body 11, and the servo motor operates to cause the upper mold body 7 to press the product downward. When the product is pressed down to the contact of the upper and lower limit posts 14, the springs 10 inside the upper mold body 7 and the lower mold body 11 are compressed, the punch 12 remains stationary, and the floating plate 9 moves the product downward. During this process, because the punch 12 is held in place by the pad 13, the punch 12 moves upward relative to the lower mold body 11, cutting the product skin into the shape of the punch 12 (the shape of the punch 12 depends on the shape of the product's logo mounting hole). The cut skin scraps enter the hollow part inside the upper mold body 7, at which point the vacuum generator is activated to suck in and collect the scraps.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
