Introduction to the Principle and Advantages of Rivetless Riveting Machine for White Goods发表时间:2022-06-06 17:04 The principle of rivetless riveting machine: The rivetless riveting machine uses a gas-hydraulic cylinder or hydraulic cylinder and a special mold to cold-extrude two or more layers of metal sheet metal, and interlock to form a riveting device with a certain compressive strength and tensile strength. . The rivetless riveting machine is suitable for joining steel plates, hot-dip galvanized plates, aluminum plates, copper plates and their non-metallic material interlayers. It is widely used in automobile manufacturing industry, central air conditioner, refrigerator and other sheet metal parts connection, ventilation duct connection, etc. Advantages of rivetless riveting: 1. The connection points are strong and reliable; 2. There are no special requirements for the product connection surface; 3. No need for bolts, reasonable cost control; 4. Configure prestressed tensioning equipment to eliminate undesirable deformation; 5. The riveting time, riveting working pressure and riveting speed are infinitely adjustable; 6. The riveting force is small, the mold shell has a long service life and a high safety factor; 7. Can produce small round dots or square dot connections; 8. There is no internal stress in the connecting area; 9. It is not easy to damage the surface coating of the product; 10. The demand for product raw materials is not high, and copper coins, aluminum plates, etc. can be used; 11. The riveting surface is bright and beautiful; 12. The whole process of riveting is vibration-free, low energy consumption and low noise; 13. Double-layer or interlayer connection can be achieved; 14. The electronic control system has built-in counting function; 15. The electronic control system is easy to use and can be switched between manual, fully automatic and automatic functions at will; 16. A properly designed mold can rivet products with different wall thicknesses; 17. Energy saving and environmental protection, zero environmental pollution discharge; 18. The machine and equipment have long service life, easy maintenance, and low maintenance cost. |
