Description
Technical field
The present invention relates to rectifying for the specific products substantially without machining or processing for metal plate or pipe, stick or profile
Straight or complex field, specially a kind of Pipe End Throat Machine.
Background technique
The line pipe of normal usage is required to pipe end ovality, wall thickness deviation and the control of outside diameter tolerance value before factory
Within the scope of certain, in the above pipe end dimensional tolerance, wall thickness deviation and outside diameter tolerance value are relatively easy to control, but pipe end
Ovality is extremely difficult in rolled, after Overheating Treatment, is further deteriorated, is unable to satisfy Customer Standard requirement.For pipe end
The more stringent marine line pipes of quality requirement, will also guarantee while requiring pipe end ovality, wall thickness deviation to meet the requirements
Ovality and inner diameter deviation value are met the requirements simultaneously.According to current seamless steel pipe processing process, tube end maching precision reaches
Less than defined requirement.
Due under hot-rolled state it is difficult to ensure that pipe end ovality further deteriorates after Overheating Treatment, in subsequent pipe
Processing cart wire process, since pipe end ovality is bad, when thread, easily substandard products such as generation black skin buckle cause vehicle
Fiber tube rejection rate is higher.
The above problem causes subsequent tube end maching that defined is not achieved because pipe end related performance indicators are unable to control
It is required that generate waste product, cause serious economic loss.
And current most of manufacturing enterprise, the enterprise of high appearance quality requirement or high added value steel product is especially produced,
It generally is equipped with pipe end necking machine.To meet the relevant performance indicator of pipe end.Existing almost all of pipe end contracting
Its clamping of mouth machine is divided into two sets of independent mechanical mechanisms with die forging, is mainly made of host, electrical system, hydraulic system etc.,
Wherein host is by rack, device for clamping mould and clamping die, punch holder and its guiding device, formed punch and closing in/sizing die, position
Set the composition such as detection device.The necking machine of this form is widely used in steel pipe's production enterprise, including the big seamless, Baosteel in Tianjin without
Steel tube factory, Chengdu Gapless Rail Factory etc. are stitched, but structure is relative complex, equipment failure rate is higher in production, especially the later period
Maintenance cost is higher, while equipment investment is larger.
There is a kind of novel Pipe End Throat Machine at present, uses clamping and die forging integrated technique, but do not have always
Thus bring human assistance release problems are resolved, it is de- that there is still a need for human assistances in the steel pipe of processing department divider lattice at present
Mould.
Summary of the invention
In order to overcome the drawbacks of the prior art, provide that a kind of structure is simple, easy to use, demoulding is easy, pipe workpiece quality is high
Hot rolling ancillary equipment, the invention discloses a kind of Pipe End Throat Machines.
The present invention reaches goal of the invention by following technical solution:
A kind of Pipe End Throat Machine, including mold, it is characterized in that: further including featured hydraulic cylinder, connecting rod, movable push-plate, activity pressure
Block and fixing seat,
The cylinder body of featured hydraulic cylinder is fixed by the connecting rod in fixing seat, promotes mainly the piston rod connection activity push-plate of hydraulic cylinder,
It is provided at least three pilot hole around central point on movable push-plate, connecting rod is through in the pilot hole of movable push-plate, encloses in fixing seat
It is provided at least three locating slot around central point, each movable holddown passes through the projection at top in locating slot, movable holddown edge
Locating slot is free to slide, and the top of movable holddown also passes through projection and is embedded in the sliding slot of movable push-plate inner sidewall, movable holddown
Bottom fixing mould, the mobile side of axis (i.e. the glide direction of movable holddown along the chute) and featured hydraulic cylinder piston rod of sliding slot
The oblique between.
The Pipe End Throat Machine, it is characterized in that: the cross section of sliding slot is T shape.
The Pipe End Throat Machine, it is characterized in that: between the axis of sliding slot and the moving direction of featured hydraulic cylinder piston rod
Angle be 1 °~30 °.
The Pipe End Throat Machine, it is characterized in that: the quantity of movable holddown is 3 pieces to 12 pieces, each movable holddown is surrounded
The central axis of movable push-plate is evenly distributed；The bottom of each mold be all the circular arc of indent and successively split be a circumference.
The present invention is in use, steel pipe is through in the through-hole that each mold bottom is formed, the piston rod of featured hydraulic cylinder (1)
It moves forward, drive activity push-plate travels forward, embedding due to being formed between movable push-plate and movable holddown by projection and sliding slot
Slot structure, and oblique between the axis of the caulking groove structure and the moving direction of featured hydraulic cylinder piston rod, push away in activity in this way
When disk travels forward, several movable holddowns and mold is driven to move toward centerline direction, mold squeezes steel pipe thus will
Pipe end full circle necking.
The present invention solves the problems, such as existing Pipe End Throat Machine, and structure is complicated, high equipment cost, also overcomes steel pipe throat
The not defect of easy mold release afterwards has many advantages, such as that structure is simple, easy to use, demoulding is easy, equipment failure rate is low, investment is less.
