Description
Technical field
The present invention relates to a kind of seamless steel pipe production, particularly a kind of leading truck of large-size horizontal piercing mill of seamless steel tube.
Background technology
At present, on seamless steel tube production chain, punch is one of capital equipment, the horizontal perforated machine mainly comprises frame, roll, roll adjusting device, guide plate, guide plate frame and taper push rod, the roll left-right symmetry is provided with two, roll is installed on the roll adjusting device, and roll adjusting device is arranged on the frame; Guide plate comprises symmetrically arranged upper guide plate and bottom guide, upper guide plate and bottom guide are installed in respectively on the guide plate frame, the guide plate frame is fixed on the frame, the taper push rod is arranged on upper guide plate, bottom guide and two symmetrical centre of pricking roller, in the time of in the space that guide plate, lower guide plate and two rolls surround on solid cylindrical material base is clamped in, the taper push rod is conflicted just at the material base center, when roll rotation, drive the material base rotation and promote material base and advance, the taper push rod then portals at the material base centre drill, make material base become seamless tubulose, and finally form seamless steel pipe; In this process, upper guide plate and bottom guide rise material base and help and guide effect.The punch of the heavy caliber seamless steel pipe of development production in recent years, be mainly used in the above seamless steel pipe of production diameter of phi 340mm, can produce steel pipe from Φ 340mm to Φ 920mm even bigger specification, produce the seamless steel pipe of different size, the position of its guide plate and spigot surface shape are all inequality, for making piercing mill of seamless steel tube can satisfy the production group apart from changing the demand big, complete in specifications, that production efficiency is high, this just requires the guide plate of punch and guide plate frame to change fast.Existing design is not change the guide plate frame, but satisfies the requirement of changing the different size guide plate by increasing transition frame between guide plate and the guide plate frame.The shortcoming of this design is: 1. locking is inconvenient, unreliable; 2. it is dumb to change guide plate; 3. pipe that can not flexible adaptation different size diameter; 4. particularly because the production group increases apart from changing, what this design brought is that roll distance and guide plate distance are conflicting, can not adapt to increasing group apart from production requirement; 5. device fabrication cost height in the time of the steel pipe of producing from Φ 340mm to Φ 920mm even bigger specification, has to design several units, as Φ 340 units, Φ 508 units, Φ 720 units, many units such as Φ 920 units, thereby the device fabrication cost is higher relatively.
Summary of the invention
The objective of the invention is to design a kind of quick replacement device of guide plate rack on large caliber perforating machine, solve the problems referred to above, it is convenient to make upper guide plate change, and can adapt to the pipe of various different size diameters, simultaneously, can reduce manufacturing cost.
For achieving the above object, quick replacement device of guide plate rack on large caliber perforating machine provided by the invention, comprise frame, upper guide plate and upper guide plate frame, upper guide plate is fixed on upper guide plate frame lower end, frame is provided with the leading truck of enclosing rectangular enclosure, the cooperation of upper guide plate frame is installed in the described rectangular enclosure, is provided with slide block around the upper guide plate frame and between the leading truck, and the leading truck side is provided with the side direction locking device; Side also uprightly is provided with balancing cylinder respectively before and after the upper guide plate frame, and the cylinder body of balancing cylinder is bearing on the frame, and the piston rod upper end of balancing cylinder is arranged on the lower end of upper guide plate frame both sides; Be positioned at upper guide plate frame both sides level on the frame and be provided with two gathering sills that are parallel to each other, be provided with the slide-and-lock frame between two gathering sills and above being positioned at the upper guide plate frame, the translateral slide plate cooperation of slide-and-lock frame is installed in the gathering sill, and slide-and-lock frame rear side is provided with and can orders about the sliding drive mechanism that the slide-and-lock frame slides along gathering sill; Uprightly be provided with screw rod in the slide-and-lock frame, conflict in upper guide plate frame upper end in the screw rod lower end, described screw rod external toothing is provided with nut, this nut is axially fixed on the slide-and-lock frame, nut circumferentially can rotate, nut is fixed with worm gear outward, and the engagement of worm gear side is equipped with the worm screw that is horizontally set on the slide-and-lock frame, and described worm screw and locking motor are in transmission connection.
Described sliding drive mechanism can be following structure: in slide-and-lock frame bilateral symmetry two rhizoid bars are set, the axis of two rhizoid bars is parallel with the length direction of gathering sill, two rhizoid bars all are in transmission connection with lazy-tongs by driven by motor, and described lazy-tongs and frame fix.Lazy-tongs can spur two rhizoid bars and be synchronized with the movement, and make the slide-and-lock frame along the length direction translation of gathering sill, abdicate upper guide plate frame upper space.
Described side direction locking device can be following structure: this side direction locking device comprises locking cylinder, and the piston rod end of locking cylinder is equipped with sphenocephaly, is provided with the wedge suitable with sphenocephaly between leading truck and the upper guide plate frame.
Be the protection screw rod, the end outside described screw rod stretches out the slide-and-lock frame is set with protective sleeve.
When the present invention works, cooperation by sphenocephaly and wedge, when the piston rod of locking cylinder stretches out, the side direction locking device can be locked in upper guide plate frame side direction in the leading truck, because screw rod is conflicted on upper guide plate frame top, make the upper guide plate frame position that can not move up, during punch work, upper guide plate can obtain good location, and self can not move; When needs replace with guide plate and upper guide plate frame, can make screw rod break away from upper guide plate frame upper end by worm gear, worm-drive, remove the slide-and-lock frame by the sliding drive mechanism side direction again, abdicate upper guide plate frame upper space; At this moment, can order about sphenocephaly and wedge disengaging, can upwards eject the upper guide plate frame by balancing cylinder again, can upwards take out the upper guide plate frame and change by locking cylinder.After replacing finishes,, upper guide plate frame and the corresponding upper guide plate changed can be installed the location once more by above-mentioned rightabout operation; Compared with prior art, the present invention has the following advantages: 1. locking is convenient, and is reliable; 2. it is flexible to replace with guide plate; 3. can flexible adaptation the pipe of different size diameter; 4. particularly can adapt to increasing group apart from production requirement; 5. device fabrication is with low cost.Adopt the present invention, producing only needs an equipment to finish from Φ 340mm to Φ 920mm.
