As we all know, sheet metal processing is connected through various processes and processes of cast iron parts. In the process of Dongguan sheet metal chassis processing, the selection of the connection method is a very important issue, which is mainly divided into welded links and bolted connections. Each of these two types of links has its own advantages.
1. Welding connection:
Welding is a technology that connects two or more metal parts through molten metal. In the processing of sheet metal chassis, spot welding, argon arc welding or laser welding are usually used for connection. Welded connections have the following characteristics:
High strength: Welded connections can provide high connection strength, making the chassis better resistant to deformation and durability under vibration and impact loads.
Good sealing: Welded connections can achieve seamless connections, avoiding water or air leakage problems that may be caused by gaps in the connections.
High reliability: The welded connection can provide a longer-lasting connection effect and is not easy to loosen or break. It is suitable for chassis under long-term use and heavy load conditions.
2. Bolt connection:
Bolt connection is a way of fastening metal parts together using threaded holes and nuts. Common bolting methods in sheet metal chassis include bolts and nuts, threaded pins, etc. Bolted connections have the following characteristics:
Easy to disassemble: Unlike welding, bolted connections can be easily disassembled and reassembled, which is suitable for situations where frequent maintenance or replacement of parts is required.
High mobility: Bolt connections can adjust the connection tightening force, allowing the chassis to be fine-tuned and aligned during installation to ensure the accuracy and stability of the overall structure.
Strong adaptability: Bolt connections can adapt to metal parts of different thicknesses and shapes, and different types and specifications of bolts and nuts can be selected as needed.
Among the two connection methods for sheet metal chassis processing, welded connections are usually suitable for situations that require higher strength and sealing, while bolted connections are more suitable for situations that require detachability. In actual processing, a mixed method of welding and bolting may also be used to take into account different needs.
Scratches on the device’s sheet metal casing may be caused by friction, wear, or other external forces. In order to prevent scratches on the sheet metal shell of Dongguan equipment, the following measures can be taken:
1. Use protective measures: During the use of the equipment, protective measures can be used to prevent scratches, such as installing protective covers, protective sleeves, etc. These protection measures can prevent direct collision and scratches on the equipment’s sheet metal casing by external forces.
2. Regular cleaning and maintenance: Regular cleaning and maintenance of the equipment’s sheet metal casing are important steps to prevent scratches. Use a soft cleaning cloth or sponge with an appropriate detergent. Avoid cleaning with harsh chemicals or sharp objects that may cause scratches. In addition, pay attention to tapping or rubbing lightly during the cleaning process, and do not use excessive force.
3. Add a protective layer: You can add a protective layer on the surface of the device’s sheet metal shell to prevent scratches. For example, use a transparent protective film or apply a protective coating. These layers can prevent direct contact with the sheet metal shell by external objects and reduce the risk of scratches.
4. Improve user awareness: Strengthen user training and awareness, educate them on the correct use of equipment, and avoid engraving, graffiti or intentional scratches on the casing. At the same time, strengthen safety reminder signs around the equipment to remind users to pay attention to protecting the equipment shell and not to collide or rub it at will.
5. Improve design and material selection: In the design and material selection of equipment, you can consider using more scratch-resistant materials, such as ceramic coatings, wear-resistant coatings, etc. In addition, well-designed details such as chamfers and grooves can reduce the possibility of bumps and scratches on the casing.
In actual operation, the above measures should be comprehensively considered according to the specific conditions and use environment of the equipment to formulate a targeted anti-scratch plan. More importantly, it is necessary to strengthen the awareness and maintenance of equipment, conduct regular inspections and carry out necessary repairs and replacements to ensure the integrity and beauty of the equipment shell.
