The utility model content
The purpose of this utility model is exactly the deficiency that exists at existing steel tube expansion, provides a kind of rational in infrastructure simple, manufactures and is easy to the three roll pipe expanding machine.
The purpose of this utility model is to realize like this, the three roll pipe expanding machine comprises memorial archway 2, pull bar 8, master cylinder 3, roll device 1, transmission device 14, poking device 4 and water spray cooling body 10, it is characterized in that adopting pull bar 8 that two memorial archways 2 are connected to become a rigid unitary, roll device 1 is installed in the integral body that two memorial archways 2 connect into, the roll 7 that hydraulic pump 15 in the transmission device 14 connects in the roll device 1 by hydraulic valve bank 16, hydraulic motor 5, water spray cooling body 10 is arranged on the top of roll device 1.Described roll device 1 comprises roll 7, backing roll 6, combination bearing case 11 and locking cylinder 12, and the two ends of roll 7 and backing roll 6 are installed in the combination bearing case 11, and are locked together by locking cylinder 12.The chute end that roll 7 and backing roll 6 are installed on the described combination bearing case 11 is equipped with the master cylinder 3 that drives roll device 1 stepless speed regulation campaign.
Constitute poking device by material toggling oil cylinder, Kick-out hook and connecting rod, constitute the water spray cooling body by high-pressure hydraulic pump, supply channel and cooling spray.The two ends of roll and backing roll are installed in the combination bearing case, and are locked together by locking cylinder, and the roll device that assembles is packed into by the chute on the combination bearing case in the memorial archway, and two memorial archways are linked as a rigid unitary with pull bar.A master cylinder is equipped with in the end of each chute, is used to spur roll device and seesaws.Hydraulic pump in the transmission device provides pressure oil, and the control driving hydraulic motor rotation by hydraulic valve bank produces rolling motion thereby drive the roll rotation.Material toggling oil cylinder in the poking device drives Kick-out hook by pull bar and is used for a hollow billet of putting on plug dialled in and is rolled in the body and rolling good hollow forging dial-out body.High-pressure hydraulic pump in the water spray cooling body provides water under high pressure, is transported to cooling spray by supply channel, sprays to the roller surface breaker roll by shower nozzle and cools off.
The utility model is rational in infrastructure simple, manufactures easily, uses easy to operately, has low speed, continuously feeding and subtract the advantage of wall hole enlargement on a small quantity.Adopt the HYDRAULIC CONTROL SYSTEM mill speed and the amount of feeding, can stepless speed regulation, thus reduce requirement to rolling temperature, improve rolling efficiency and pipe expanding and handle quality.Good economic benefits is arranged and improve using value.
