Precision parts inside the trigger device: a powerful tool for precision manufacturing of automobile airbag modules
In the field of automobile safety, the airbag module is the last line of defense to protect the safety of passengers at critical moments, and its importance is self-evident. The trigger device is the core component of the airbag module, and its internal precision parts are directly related to whether the airbag can be deployed accurately and reliably in an instant. Today, we will deeply explore the manufacturing process of the precision parts inside the trigger device, and the key role played by large-scale large-taper machine tool wire cutting processing in it.
Have you ever thought about what ensures that the airbag can pop out instantly at the critical moment and provide a safety barrier for the driver and passengers? The answer lies in the precision parts inside the trigger device. The large-scale large-taper machine tool wire cutting machine is the key to achieving this precision manufacturing.
Product analysis and challenges of case customers
Let’s take a leading automotive safety system supplier as an example (hereinafter referred to as “the customer”), whose airbag modules are known for their high reliability, high sensitivity and fast response. During the production process of its products, many key components need to be processed using large-scale large-taper machine tool wire cutting machines, the most representative of which are the precision parts inside the trigger device.
The customer has extremely high requirements for the accuracy, surface quality and consistency of the precision parts inside the trigger device. Specifically, the parts mainly involve the following key components:
Trigger housing: As a protective shell for internal precision parts, the trigger housing needs to have high precision and high strength to ensure that the internal parts can still work stably in extreme environments. The complex shape and fine size of its internal cavity pose extremely high challenges to processing technology.
Firing pin: The firing pin is the core component of the trigger mechanism, responsible for firing quickly after receiving the signal, thereby triggering the deployment of the airbag. The dimensional accuracy and surface finish of the firing pin directly affect its movement speed and reliability. Its slender shape and extremely high dimensional tolerance requirements make it extremely difficult to process.
Slider: The slider plays a role in transmitting force and guiding the movement of the firing pin in the trigger device. The accuracy and surface roughness of its slideway are crucial to the smooth movement of the firing pin. The difficulty in processing the slider lies in its thin-walled structure and complex shape, which is easy to deform during the processing process.
Advantages of Wire Cutting Processing on Large and Large Taper Machine Tools
In view of the above-mentioned processing difficulties, the large-scale large-taper machine tool wire cutting processing technology has shown its unique advantages:
High precision: Zhikai CNC's large-scale large-taper machine tool wire cutting machine adopts advanced CNC system and precise mechanical structure, which can achieve micron-level processing accuracy and perfectly meet the stringent requirements of precision parts inside the trigger device. For example, the diameter tolerance of the firing pin can be controlled within ≤±0.00 3 mm to ensure its movement accuracy.
Complex shape processing capability: Large taper wire cutting technology can process various complex shaped parts, including trigger housings with complex inner cavities and sliders with fine slides. Zhikai CNC's machine tools have a maximum taper of ±30°, which can easily cope with the processing needs of various complex structures.
High surface quality: Wire cutting uses the principle of electro-erosion and does not generate mechanical cutting forces, so it can obtain extremely low surface roughness values (Ra ≤ 0.7-1.4 μm), reduce friction and wear of parts, and improve their service life and reliability.
One-time molding: For some complex parts, such as the trigger housing, large-scale large-taper machine tool wire cutting machines can complete the processing of multiple surfaces in one clamping, avoiding the errors caused by multiple clampings and improving processing efficiency and accuracy.
