Sleeve building line is used to produce sleeved type air spring bellows with diameter below 80mm. The building line includes three in one feeding rack, conveyor belt type building machine and four station vulcanizing machine. 1 meter long sleeve bellow can be made at one time with high production efficiency.
Coreless rolling-up machine, used for air spring bellow, is to wrap the steel rings into rubber sheet at the two ends of the bellow after bellow forming. After rolling up process, the bellow can then be holed and vulcanized. Rolling-up is an important process in the production of air spring.
Punching machine, also known as bellow punching machine, is an auxiliary equipment in the production of air spring. It is used to punch the bellow at the joint of the ring and the rubber before vulcanization. These punched holes are opened to the air to ensure the precision fitting of the ring and the rubber when the air spring is vulcanized. This can ensure the quality of the air spring.
Bellows builder is used to make rubber bellows for airspring. The inner layer, the cord fabrics and the outer layer rubber sheets are rolled into the bellows through the building drum.
Then turn up by the flip over device, the steel rings are wrapped into the bellows.
The rack is the supporting equipment of the bellows building machine, which is used for the fixed-length cutting of sealing sheet, endurance cord fabrics and oil-resistant outside rubber sheet. The rack has various forms. Our company’s six station vertical rack can be used for fixed length cutting of up to six kinds of materials.
Airspring lifetime test machine is designed referring to the national stand, GT/T 13061-2017.It is used to test bellows type and combined type airspring.
Sleeved type airspring, also called sleeve type airspring. This machine is designed according to national standard GB/T 13061-2017, and used for testing the longevity of diaphragm airspring.
