Description

Technical Field

[0001] This utility model relates to the field of punching die technology, and in particular to a punching die for an automotive airbag bracket. Background Technology

[0002] With the rapid development of modern transportation and the increasing demands for vehicle safety, automobiles have become an indispensable means of transportation in people's lives. The automotive industry has also experienced rapid growth. As a key component of the vehicle's passive safety system, the importance of airbags is self-evident. Airbag brackets are crucial components that support and secure airbags, directly affecting whether the airbags can deploy properly and provide protection in the event of an accident. The production process of airbag brackets often requires punching various molds of different specifications and sizes to meet the production needs of different vehicle models and design requirements. Traditional punching molds typically use fixed, single-specification mold fixing methods, such as simple bolt tightening or slot limiting, requiring operators to spend a significant amount of time adjusting or replacing them. The corresponding fixing accessories may even require readjusting the entire punching die device, making the operation cumbersome and complex. This results in a long time required for die replacement and fixing, seriously affecting production preparation efficiency. Traditional fixing methods make it difficult to ensure that the die maintains a stable position during punching, easily leading to shaking and displacement, resulting in quality problems such as inaccurate punching position and hole diameter deviation. Traditional punching dies lack effective design for debris cleaning, often requiring manual cleaning with tools, which is time-consuming, labor-intensive, and inefficient, failing to ensure a clean and orderly production environment. Even if some traditional punching dies are equipped with debris collection devices, their structures are often complex and unreasonable, making the complicated disassembly process time-consuming. Therefore, we propose a punching die for automotive airbag brackets to solve this problem. Utility Model Content
