Abstract
The invention discloses a hold-down balancing mechanism of a rotary frame overall replacing three-roll pipe mill, which solves the technical problem that the quick-opening cylinder outer wall and the fixed torii cavity of a traditional rotary frame overall replacing three-roll pipe mill are easy to be rusted. The mechanism comprises a balancing cylinder (13), a balancing cylinder connecting rod (3), and a worm and worm gear seat (14) and a hold-down screw (15) which are arranged on a fixed torii; a circular rubber seal ring (5) is arranged between the balancing cylinder connecting rod (3) and a quick-opening hydraulic cylinder spherical pad (4); a fixed key (8) is arranged between a quick-opening hydraulic cylinder (6) and a quick-opening hydraulic cylinder bushing (7); the window (11) of a quick-opening hydraulic cylinder oil pipe is arranged on the fixed torii (10) on the outer side; and the window (11) of the quick-opening hydraulic cylinder oil pipe is provided with a window dust-proofing cover (12). The hold-down balancing mechanism of the rotary frame overall replacing three-roll pipe mill improves the working conditions of a quick-opening cylinder, prevents various faults, ensures normal rolling, and facilitates adjustment and maintenance.
Description
Technical field
The present invention relates to a kind of seamless steel pipe hot-rolling equipment, particularly a kind of roll hold-down balancing mechanism of seamless steel pipe three-roll milling train.
Background technology
The roll of the rotary frame overall replacing three-roll pipe mill of prior art leaves the cylinder oil-in soon and all is positioned at fixedly memorial archway inboard.When pipe mill is worked, the iron scale that this zone can produce a large amount of water, water vapour and splash, these impurity can connect the window that oil pipe holds and enter in the inner chamber of holding cylinder soon for holding the cylinder oil-in soon from fixing memorial archway is inboard, cause opening soon the cylinder outer wall and fixedly the memorial archway inner chamber get rusty, make equipment produce fault, the ordinary production of influence.
Summary of the invention
The hold-down balancing mechanism of a kind of rotary frame overall replacing three-roll pipe mill provided by the invention has solved and has opened cylinder outer wall and the fixing technical problem that gets rusty easily of memorial archway inner chamber soon.
The present invention overcomes the above problems by following scheme:
A kind of hold-down balancing mechanism of rotary frame overall replacing three-roll pipe mill, comprise, compensating cylinder, compensating cylinder connecting rod, be arranged on the worm and gear seat on the fixing memorial archway and depress leading screw, at described compensating cylinder connecting rod and open soon and be provided with the ring-shaped rubber sealing ring between the hydraulic cylinder ball ring, be provided with retainingf key opening hydraulic cylinder soon and open soon between the hydraulic cylinder lining, the window of opening the hydraulic cylinder oil pipe soon is arranged on the outside fixedly on the memorial archway, is provided with the window dust cover in the window of opening the hydraulic cylinder oil pipe soon.
Be provided with at the middle part of described window dust cover and open the hydraulic cylinder oil pipe soon, and the window dust cover fixedly is bonded together outward with the tube wall of opening the hydraulic cylinder oil pipe soon.
The invention has the beneficial effects as follows and prevent that effectively sealing, water vapour and iron scale enter the memorial archway inner chamber that cylinder is opened in installation soon, improve the condition of work of opening cylinder soon, avoid the generation of various faults, guarantee normally carrying out of rolling work, and convenient the adjustment and maintenance.
