Description
Technical field
The invention mainly relates to a kind of die cutting devices for overlap in drill pipe friction, are mainly used for drill pipe friction
The removal of interior friction welding (FW) circle is processed in processing technology.
Background technique
Friction welding (FW) processing technology is also commonly used for a variety of industries, leads in geological prospecting, mine engineering and oil drilling
It is used in the drilling tool processing in domain as commonly used equipment, is indispensable important manufacturing process, friction welding apparatus in processing technology
Process principle be to dock high speed rotations using two workpiece, the process of hot fusion is generated by spin friction, welding is completed
Welding overlap can be remained in welding surface afterwards, workpiece is that the surfaces externally and internally in welding of hollow pipe fitting can remain overlap.
Mine drill stem drilling tool product is the metal material workpiece of two end connectors and body of rod unlike material, passes through the quenched place of vacuum
Two end connectors are carried out cure process by reason, and two end connectors and the body of rod are then carried out friction welding using friction welding apparatus, by
It is that hollow structure can generate inside and outside friction welding overlap in the welding process in the body of rod, is all to utilize machine tool under normal circumstances
Flash structure except going, but while nearly this year, mining industry was grown rapidly, new drilling tool successive generations of products, wherein greatly
Latus rectum hollow structure inside drilling rod product is internal big orifice design structure, it is therefore an objective to penetrate gas screen casing by the body of rod
In drilling, drilling operation efficiency is improved.Add man-hour requirement to having carried out friction welding (FW) carrying out big orifice hollow structure inside drilling rod
Drilling rod after connecing carries out cutting burrs, and outer overlap can carry out processing excision or included using friction welding apparatus on universal machine tools
Overlap removal function be removed, but the removal of interior overlap is never well solved method.
Summary of the invention
The content of present invention is to provide a kind of die cutting device for overlap in drill pipe friction, by hydraulic control system,
Operation with closed ring is carried out to integral device, using oil cylinder propulsion mode, oil cylinder front end and interior weldering circle cutting head are attached, in machine
Two reciprocity oil cylinders and interior weldering circle cutting head are respectively set in bed bed body both ends, and the cutting head center of interior weldering circle is high consistent,
Machine tool body longitudinal direction two sides are provided with body of rod clamping mechanism, carry out horizontal clamping to the body of rod by body of rod clamping mechanism, then by
Both ends oil cylinder drives interior weldering circle cutting head to be moved toward one another, and cutting head enters two end connector hollow parts, and reaches interior overlap
Place, internal overlap carry out axial punching, to guarantee that diameter of bore meets lower screen casing requirement, it is automatic to reach oil cylinder after removal requires
It retracts, to complete a closed loop processing process.
According to a kind of die cutting device for overlap in drill pipe friction, cutting head is enclosed using oil cylinder and interior weldering
As major impetus applying mechanism, oil cylinder and interior weldering circle cutting head are as punching mechanism, and transverse ends use on machine tool body
Relative mode is arranged, i.e., two punching mechanisms are respectively set in machine tool body both ends, to guarantee to fly in two ends of drill
Side carries out while removing.
According to a kind of die cutting device for overlap in drill pipe friction, by utilizing body of rod clamping structure to bar
Body carries out clamping, and body of rod clamping mechanism is the design of opposite opened fixture, using two split fixture clamping body of rod outer round surface, passes through
Clamping can be carried out to round bar structure, multiple edge body bar structure, special-shaped bar structure by processing fixture of different shapes, split
Fixture provides power by two oil cylinders and is moved.
According to a kind of die cutting device for overlap in drill pipe friction, using Closed Loop Control Unit, Mei Geyun
Dynamic beat carries out overall control by control platform, by control platform and each distribution oil cylinder and hydraulic power unit connector,
By hydraulic power unit output hydraulic pressure power, the fortune to control different oil cylinders is adjusted in the master control that control platform carries out hydraulic power
It is dynamic, to realize that a kind of body of rod for the die cutting device of overlap in drill pipe friction steps up and interior overlap Punching Technology.
Detailed description of the invention:
Fig. 1 is a kind of schematic diagram for the die cutting device of overlap in drill pipe friction
Fig. 2 is not remove inner flash in drill stem schematic diagram
Fig. 3 is removal inner flash in drill stem schematic diagram
Wherein, 1-hydraulic power unit, 2-machine tool bodies, 3-control platforms, 4-promote oil circuit, and 5-rollback oil circuits, 6-always return
Cutting head, 11-outer connections are enclosed in oil circuit, the total road of 7-oil pumps, 8-punching propelling cylinders, 9-body of rod clamping oil cylinders, 10-interior welderings
Head, 12-interior connectors, the 13-bodies of rod, 14-interior overlaps.
Referring to the figure covered in attached drawing and specific practical it is described as follows:
Output bit and oil according to as shown in the figure, in a kind of hydraulic power unit 1 for the die cutting device of overlap in drill pipe friction
The road Beng Zong 7 connects, by the total 7 output services power of road of oil pump to control platform 3, the oil return position in hydraulic power unit 1 and the oil that retracts
Road 6 is attached and is attached by rollback oil circuit 6 with control platform 4, and the operation power exported through the total road 7 of oil pump passes through control
Platform 3 processed carries out conversion by promoting oil circuit 4 to be delivered to punching propelling cylinder 8 and body of rod clamping oil cylinder 9 respectively, and punching promotes oil
Cylinder 8 is that symmetrical structure is fixed on machine tool body 2, and is attached at one end with interior weldering circle cutting head 10, is promoted by punching
Oil cylinder 8 promotes interior weldering circle cutting head 10 to be moved, and body of rod clamping oil cylinder 9 is all that symmetrical structure is fixed on machine tool body 2 and leads to
Cross body of rod fixture of different shapes and carry out the clamping body of rod, be punched propelling cylinder 8 and body of rod clamping oil cylinder 9 on be provided with rollback oil
Road 5 guarantees the rollback of movement.
According to the body of rod 13, both ends carry out friction welding (FW) welding with outer connector 11 and interior connector 12 respectively, lead to
It crosses friction welding (FW) welding and generates interior overlap 14, by soldered 13 clamping of the body of rod on the clamping mechanism on body of rod clamping oil cylinder 9,
Then it drives interior weldering circle cutting head 10 to be punched out interior overlap 14 to center movement using punching propelling cylinder 8, completes this
It retracts after one circulation, fetches the body of rod 13, entire motion process passes through control platform 3 and controlled.
Anyone should learn the structure change made under the inspiration of the present invention, it is all with it is of the invention have it is same or similar
Technical solution, fall within the scope of protection of the present invention.
Technology not described in detail in the present invention, shape, construction portion are well-known technique.
