Bellows-type protective cover: Impact-resistant and wear-resistant, putting on a tough "armor" for the equipment

1. Selection of advanced materials

The impact resistance of the accordion-type protective cover is first of all due to the advanced materials it uses. Common materials include high-strength nylon, polycarbonate, and special alloys. High-strength nylon has excellent toughness and impact resistance. When it is impacted by external forces, it can absorb energy through the slippage and deformation of the molecular chain, thereby reducing the impact of the impact on the equipment. For example, on some small and medium-sized machine tools, the accordion-type protective cover made of high-strength nylon can effectively resist the impact of metal chips splashed during processing and protect the key components of the equipment.

Polycarbonate is known for its high transparency and high impact resistance. It not only allows operators to clearly observe the operating status of the equipment, but also maintains the integrity of the structure when it is impacted. In some occasions where real-time monitoring of equipment operation is required and the working environment is relatively harsh, such as packaging equipment protection on food processing production lines, polycarbonate accordion-type protective covers can not only meet observation needs, but also provide reliable impact protection. Special alloy materials have higher strength and hardness, and are suitable for some heavy equipment with extremely high protection requirements.

2. Unique structural design

In addition to the choice of materials, the unique structural design of the accordion-type protective cover also adds a lot to its impact resistance. It adopts an accordion-type folding structure, which enables the protective cover to deform elastically like a spring when it is impacted, thereby buffering the impact force. When the impact force disappears, the protective cover can quickly return to its original state and continue to play a protective role. At the same time, the edges and connection parts of the protective cover are usually reinforced to increase the overall strength and stability. For example, high-strength bolt connections or welding processes are used to ensure that there will be no loosening or falling off when impacted. In addition, some accordion-type protective covers will also have reinforcing ribs inside to further improve their impact resistance.

3. Guarantee of wear resistance

The wear resistance of the accordion-type protective cover is mainly due to its advanced surface treatment technology. Common surface treatment methods include spraying wear-resistant coatings, electroplating hard chrome, etc. Spraying wear-resistant coatings can form a hard, wear-resistant protective film on the surface of the protective cover, which effectively resists friction and wear. For example, the use of polytetrafluoroethylene (PTFE) coating not only has excellent wear resistance, but also has good self-lubricating properties, which can reduce the friction between the protective cover and the equipment or other objects, and extend the service life of the protective cover. Electroplating hard chrome is to plate a layer of hard chrome on the surface of the protective cover. Hard chrome has extremely high hardness and wear resistance, which can significantly improve the wear resistance of the protective cover. In some occasions with extremely high requirements for wear resistance, such as the protection of mold processing equipment, the accordion-type protective cover plated with hard chrome can withstand frequent friction without obvious wear.
