Description
Technical field
The invention belongs to machinery Transporting equipment field, be specifically related to transition roller-way after a kind of novel PQF tandem mill.
Background technology
PQF is as MPM tube rolling mill, before hollow forging shuts out from tandem mill, do not completely disengages from tandem mill, hollow forging
Have to enter into winding arbor extraction press and realize de-rod, complete the process that plug is drawn out of from hollow forging, the hollow forging between tandem mill and winding arbor extraction press
Conveyor roller and bracket are commonly called transition roller-way.Hollow forging afterbody all comprises a tail triangle, its dimensional profile commonly greater than
Hollow forging diameter, during hollow forging transports, tail triangular portions usually comes in contact with bracket bottom surface, is risen by hollow forging, and deviation is rolled
Line processed, makes hollow forging bounce, and causes hollow forging to collide with transport roller, hits recessed in waste tube-surface formation, reduces waste tube-surface
Quality, causes hollow forging to scrap time serious, the most also can will cause do not completely disengage from plug deviation roll line, easily make plug with
Roller surface collides, and causes the damage of plug；And for the hollow forging of different shaped jet holes, need transition roller-way carries out height
Adjust, relatively complicated, greatly reduce production efficiency.
Therefore, develop for problem above a kind of for different shaped jet holes hollow forging, hollow forging tail triangle collision can either be avoided
Cause damage, also be able to ensure that the transition roller-way of stable transport is those skilled in the art institute urgent need to solve the problem simultaneously.
Summary of the invention
For solving the problems referred to above, the invention discloses transition roller-way after a kind of novel PQF tandem mill.

Connecting, this design makes the telescopic end of hydraulic jack when stretching out with retraction, it is possible to drives conveying roller to decline and rises, according to tool
Body situation avoids waste the triangle, transports hollow forging simultaneously.
Specifically, when the telescopic end of hydraulic jack stretches out, conveying roller is driven to decline by oscillating arm mechanisms, high less than bracket
Degree, further such that waste the triangle avoids conveying roller roll surface completely；When the telescopic end of hydraulic jack is retracted, by swing arm machine
Structure drives conveying roller to rise, and coordinates the bracket risen so that conveying roller, when carrying the hollow forging of different shaped jet holes, all can ensure that famine
The centrage of pipe coincides with roll line.
As preferably, bracket includes hollow forging supporting plate, tail triangle supporting plate and guides side plate；The two ends of tail triangle supporting plate are higher than tail
In the middle part of triangle supporting plate；The quantity of hollow forging supporting plate is two, is connected to the both sides, top of tail triangle supporting plate；Guide the number of side plate
Amount is also two, symmetrically and be connected to the upper end of two hollow forging supporting plates.
Bracket in the present invention is by hollow forging supporting plate, tail triangle supporting plate and guides side plate and forms, wherein tail triangle supporting plate
High-end designs is the middle part of tail triangle supporting plate, is connected in two hollow forging supporting plates of both sides, tail triangle supporting plate top, bracket plate
An Intermediate Gray reeded spill is integrally formed；Guiding side plate in the present invention is also configured as two, tilts to be connected to respectively
Two hollow forging supporting plate upper ends, when playing guide effect, also have certain position-limiting action.
As preferably, the two ends of tail triangle supporting plate are contour, and symmetrical about its place, center vertical section；Guide side plate
It it is 5～10 ° with the angle of perpendicular.
In the present invention, tail triangle two ends of bearing plate is contour, and symmetrical about place, center vertical section, and guide side plate with
The angle of perpendicular is designed as 5～10 °, this angle enable to guide side plate while there is guide effect, also have
Buffer limit effect so that hollow forging is always positioned at two and guides between side plate.
As preferably, hydraulic jack is horizontally disposed with；Conveying roller supports the side of seat and is provided with conveying roller adjustment ring；Oscillating arm mechanisms
Two ends outfan with conveying roller adjustment ring and hydraulic jack respectively be rotationally connected.
In the present invention, hydraulic jack is designed as level, and conveying roller supports seat side and is provided with the conveying pipe adjustment being easy to connect
Ring, the two ends of the oscillating arm mechanisms in the present invention are rotationally connected with the outfan of conveying roller adjustment ring and hydraulic jack respectively, should
Structure make the present invention pass through hydraulic jack regulation conveying roller height the most flexible.
As preferably, the bottom of bracket is the most vertically-mounted cushion block.
The present invention is also vertically-mounted in the bottom of bracket a cushion block, and the quantity of cushion block or the most optional, it is simple to
Drive bracket can be supported by cushion block after carrying out altitude mixture control at bracket hoist cylinder.
As preferably, hollow forging supporting plate, tail triangle supporting plate pass through to be weldingly connected with guiding side plate.
In the present invention, hollow forging supporting plate, tail triangle supporting plate and guiding side plate are optional by being weldingly connected, it is possible to ensure this
The stability of bracket in invention, and if need the present invention while keeping stablizing, additionally it is possible to convenient dismounting, in the present invention
Hollow forging supporting plate, tail triangle supporting plate and guiding side plate be may select and be connected by grafting.
The present invention is compared with existing design, while ensureing that hollow forging stably transports, it is to avoid waste the triangle is because connecing
Touching is hit and is bounced, and causes waste tube-surface to occur hitting concave defect；It is favorably improved hollow forging quality and produces lumber recovery, reducing core
Rod damage, reduces steel pipe manufacturing cost；Simple in construction, equipment investment are few, and maintenance cost is low；Reliable, it is possible to realize precisely
Adjust, stopped production equipment and the generation of personal safety accident.
